I-W-Beam kanye ne-Thrie-Beam Highway Guardrails: Ukuhlaziywa Kwemakethe Yomhlaba Wonke

Imigwaqo emikhulu - ikakhulukazi yonke indawo I-W-beam (umzila wensimbi kathayela onamagagasi amabili) kanye I-Thrie-beam (i-three-wave rail) imiklamo - ingamathuluzi abalulekile okuphepha emgwaqeni. Lo mbiko uhlaziya imakethe yalezi zindlela zokuqapha ezifundeni ezinkulu (eNyakatho Melika, eYurophu, eMpumalanga Ephakathi, eNingizimu Melika, e-Asia Pacific), okuhlanganisa namagama okusesha asendaweni, abashayeli bezidingo, kanye nezimbangi ezibalulekile esifundeni ngasinye.

Imigomo Yokusesha Yasendaweni

Abasebenzisi baseNyakatho Melika basesha kakhulu ngesiNgisi besebenzisa amagama afana nala "unogada" or "i-highway guardrail." Kwezinye izingxenye ze-US (isb. eNyakatho-mpumalanga), "umzila wesitimela" iphinde isetshenziselwe ukushintshana ngezithiyo eziseceleni komgwaqo (Udidekile: Ingabe i-Gaurdrail noma i-Guiderail: r/civilengineering - Reddit). Ukucaciswa kwemboni kuvame ukusebenzisa amagama abanzi njengokuthi “Isithiyo sokuphepha emgwaqeni” or "umgoqo wethrafikhi", kodwa ngokukhuluma "unogada" ihlala isezingeni. Imigomo yomkhiqizo othize efana "I-W-beam guardrail" futhi "I-Thrie-beam guardrail" zivamile uma usesha lezi zinhlobo ezithile. E-Canada, igama lesiNgisi liyafana, kuyilapho izifunda ezikhuluma isiFulentshi (isb. i-Québec) zisebenzisa "glissière de sécurité" (ngokwezwi nezwi “isilayidi sokuphepha”) kuma- guardrails womgwaqo omkhulu. EMexico (ingxenye yeNyakatho Melika), amagama eSpanishi anjengokuthi "barrera de contención" (umgoqo wokuqukethwe) noma "Guardraíl" zisetshenziselwa ukuvikela (I-Guardarrail – Wikipedia, i-encyclopedia yamahhala). Abasebenzisi bangaphinda baseshe ngokwejwayelekile noma ngokucaciswa (isb. "AASHTO M180 guardrail" okuyizinga lase-US le-W-beam guardrails).

Isidingo Semakethe namathrendi

INyakatho Melika inomuntu ovuthiwe kodwa isidingo esiqinile zokuqapha umgwaqo omkhulu eziqhutshwa ukugcinwa komgwaqo okuqhubekayo, ukuthuthukiswa kokuphepha, kanye nokutshalwa kwezimali kwengqalasizinda entsha. I-US ikakhulukazi ibambe a isabelo semakethe esibalulekile ngo-2023 futhi kulindeleke ukuthi qhubeka nokubusa kwayo emakethe ye-Guardrail ngenxa yenethiwekhi yomgwaqo omkhulu esungulwe kahle kanye nemithetho eqinile yezokuphepha (Ucwaningo lweMakethe ye-Highway Guard Rails: Ucwaningo Olujulile lwango-2032). Umgqugquzeli omkhulu kwaba uMthetho Wokutshalwa Kwengqalasizinda Nemisebenzi ka-2021, owaba U-$110 billion wemigwaqo namabhuloho kanye nokunye U-$11 billion wokuphepha kwezokuthutha izinhlelo (Umthetho Wokutshalwa Kwengqalasizinda Nemisebenzi - Wikipedia). Lokhu kukhuphuka kwezimali, kanye nezinhlelo zomgwaqo onguthelawayeka ezisezingeni likahulumeni, kubhebhezela ama-oda amakhulu okushintsha nokufakwa kwe- guardrail. Ukwakhiwa kwemigwaqo nokunwetshwa kwemiklamo kuyanda (kuhlanganise nemigwaqo emisha kanye nemisebenzi yamabhuloho), okugcina isidingo siqinile. E-Canada, izinhlelo zikahulumeni nezesifundazwe zokuthuthukiswa kwemigwaqo zifaka isandla ekuthengeni i-Guardrail, ikakhulukazi ku-Trans-Canada Highway kanye nemigwaqo emikhulu yasemadolobheni. Ukuthuthukiswa komgwaqo onguthelawayeka waseMexico kanye nokwandiswa kwemvume yemigwaqo ekhokhelwayo nakho kuqhuba isidingo semigwaqo emisha yokuqapha emigwaqweni esanda kwakhiwa noma ethuthukisiwe. Idatha yokugeleza kwezohwebo ikhombisa ukuthi iNyakatho Melika yanelisa iningi lesidingo sayo sokuqapha ukukhiqizwa kwasekhaya, nakuba i-Mexico ne-US zihlanganyela ekuphakeleni kwemingcele kanye nokunye okushibhile kwamanye amazwe (isb. okuvela e-Asia) ngezicelo ezingabalulekile. Sekukonke, imakethe ye-Guardrail yaseNyakatho Melika zizinzile futhi zikhulu, ngokukhula okuhambisana nokusetshenziswa kwengqalasizinda kanye neziyalezo zokuphepha.

Europe

Imigomo Yokusesha Yasendaweni

Imakethe yaseYurophu enezilimi eziningi isebenzisa amagama ahlukahlukene emigwaqweni eqapha umgwaqo. E-UK nase-Ireland, amagama ajwayelekile "umgoqo wokuphahlazeka", “umgoqo wokuphepha”, noma ngokwethukela "Isithiyo se-Armco." (Igama elithi “Armco” seliyinkomba evamile kuma-guardrails e-W-beam, asuka enkampanini yensimbi ye-Armco.) I-Continental Europe isebenzisa amagama olimi lwendawo: isibonelo, French kungcono "glissière de sécurité" (isitimela samaslayidi sokuphepha), ku German "Leitplanke" or "Schutzplanke" (ipulangwe eliqondisayo/ipulangwe lokuvikela), ku Spanish "barrera de seguridad" or "Guardraíl." I-Colloquially eSpain, ama- guardrails nawo abizwa "quitamiedos" (“abasusa ukwesaba”) (I-Guardarrail – Wikipedia, i-encyclopedia yamahhala). Ngaphakathi Italian, amagama ajwayelekile ahlanganisa "ujantshi wonogada" (okuvame ukubhalwa njengamagama amabili) kanye "bionda" (ebhekisela kuphrofayela yegagasi eliphindwe kabili) (I-Guardarrail – Wikipedia, i-encyclopedia yamahhala). Ezinye izibonelo: IsiPolish sisebenzisa okuthi “bariera drogowa”, isi-Swedish “vägräcke”, njll., kodwa amagama esiNgisi afana nala "unogada" or "umgoqo wokuphahlazeka" aziwa kabanzi kulo lonke elaseYurophu ezimeni zobuchwepheshe. Ukwengeza, isikhathi esisemthethweni se-EU sithi "Isistimu yokuvimbela imoto (VRS)", ehlanganisa izinsimbi zokuqapha ngaphansi kwezinga le-EN 1317. Abathengi nabacacisi baseYurophu bavame ukucinga ngokwejwayelekile (isb. “EN 1317 isithiyo sokuphepha i-N2 W2”) noma ngegama/umkhiqizo womkhiqizo ngenxa yezigaba zokusebenza ezisezingeni e-EU.

Isidingo Semakethe namathrendi

IYurophu ine a inethiwekhi yemigwaqo ethuthuke kahle nezidingo eziqhubekayo zokulungisa i-Guardrail, ukushintshwa, kanye nokuthuthukiswa. Imakethe iqhutshwa ukugxila kwesifunda kwezokuphepha emgwaqeni (izinhlelo ze-Vision Zero, iziqondiso zezokuphepha emgwaqeni ze-EU) kanye nokulungiswa kwengqalasizinda endala. Amazwe aseNtshonalanga Yurophu (njengeJalimane, iFrance, i-UK) abonisa kakhulu ukufunwa esikhundleni - ukushintsha izindonga zokuqapha ezindala noma ezilimele ukuze kuhlangatshezwane namazinga amasha (isb., ukuthuthukela kumasistimu athobelana ne-EN 1317 kanye nokwengeza ukuvikelwa kwezithuthuthu ngaphansi komzila). I-Eastern and Southern Europe iyanikela isidingo sokukhula njengoba benweba futhi benza imigwaqo emikhulu nemigwaqo ibe yesimanjemanje ngezithiyo ezintsha zokuphepha, ezivame ukuxhaswa izinhlelo zengqalasizinda ze-EU. I-Europe iyisifunda esivelele sokuqapha, esisekelwa imithetho eqinile yokuphepha kanye nesiko lokuthuthuka okuqhubekayo (Ucwaningo lweMakethe ye-Highway Guard Rails: Ucwaningo Olujulile lwango-2032).

Ukutshalwa kwengqalasizinda emigwaqeni kusalokhu kuqinile: Ikhomishana YaseYurophu kanye nohulumeni kazwelonke babela isabelomali esibalulekile sokulungiswa komgwaqo omkhulu nokwandiswa unyaka ngamunye. Isibonelo, i-EU's Connecting Europe Facility kanye nezinhlelo zikazwelonke ezihlukahlukene ziqinisekisa ukufakwa okuqhubekayo kwe- guardrail kumaphrojekthi amasha (isb., izandiso ze-Trans-European Transport Network). Ngaphezu kwalokho, izinhlelo zokunciphisa ukushona kwabantu emgwaqeni ziholele ekutheni ama-guardrails asebenza kahle kakhulu (enamazinga aphezulu okubamba kanye nokuchezuka okuphansi) ukufakwa ezingxenyeni zomgwaqo eziyingozi, okuqhubezela phambili isidingo sezivimbio ezikhethekile ze-thrie-beam kumabhuloho naphakathi. Amandla okungenisa/ukuthumela e-Europe abandakanya uhwebo oluwela imingcele - isb, abakhiqizi bezwe elilodwa le-EU abahlinzeka ngamaphrojekthi kwelinye - kodwa jikelele, imakethe ihlinzekwa ngabakwa-EU. ukukhiqizwa kwesifunda. I-Europe inabakhiqizi abaningi basekhaya abahlangabezana nezidingo zokumaka ze-EN 1317 CE, futhi amanani entengo ensimbi aqinisekisa ukuthi ukunikezwa kwendawo kuhlala kuncintisana. Kafushane, isidingo saseYurophu se-W-beam kanye ne-thrie-beam guardrails siwukuthi engaguquki, ngokukhula ezifundeni ezisathuthuka kanye nemijikelezo yokushintsha/yokuthuthukisa ezifundeni ezithuthukile ezigcina imakethe enempilo.

Izimbangi ezinkulu

Imakethe ye-Guardrail yase-Europe ihlukaniseke ngandlela thize kuwo wonke amazwe, kodwa inani labadlali abakhulu lisebenza kwamanye amazwe:

Izithiyo ze-Tata Steel zenzelwe ukumunca amandla aphezulu (Izithiyo zomgwaqo omkhulu | Tata Steel UK). I-Tata inikeze lezi ikakhulukazi e-UK nase-Netherlands. Nakuba i-Tata Steel yaziwa kakhulu ngensimbi engaphekiwe, uphiko lwayo oluvimbela umgwaqo omkhulu lubamba indawo lapho kufakwa khona izicelo ezikhethekile (okuhlanganisa nezinsimbi zonogada ezisebenza ngaphandle komgwaqo (Isitimela sonogada bensimbi - OFF ROAD - TATA STEEL - ArchiExpo)). Uhlobo alukho yonke indawo njenge-Hill & Smith noma i-Saferoad kuma- guardrails, kodwa luqhudelana naye oluphawulekayo ikakhulukazi kumaphrojekthi adinga ukuklanywa okuhlanganisiwe nokuhlinzekwa (angasebenzisa ukukhiqizwa kwawo kwensimbi ukuze kuzuze izindleko).

Ezinye izimbangi eYurophu zihlanganisa I-MDS Barriers (Spain), I-Industrie Metallurgiche SpA (Italy), I-SEG Metal (Eastern Europe), kanye namafemu amaningi aqondene nezwe elithile. Ngokwesibonelo, France inemisebenzi ye-ArcelorMittal yesiFulentshi futhi UTertu (okwenza izinsika zensimbi+ zokhuni zemigwaqo ebukekayo). igalikuni, evame ukuhlanganiswa ngokwengxenye ne-Europe, abakhiqizi abangabasingathi bathanda Makstil, Otoyol ekhiqiza i-EN 1317 imigqa yokugada futhi ithumele e-EU naseMpumalanga Ephakathi; Izinkampani zaseTurkey seziphenduke abahlinzeki abancintisana nezindleko zamaphrojekthi aseMpumalanga Yurophu. Imakethe yaseYurophu ngokuvamile idinga amasistimu anemakwe e-CE ahlolwe nge-EN 1317 ngayinye, ngakho-ke ukuncintisana kuzungeza ekusebenzeni okuqinisekisiwe. Kukhona futhi umkhuba we yesifundvo, ngamaqembu amakhulu afana ne-Saferoad edonsa abakhi bendawo abancane, nabadlali bamazwe ngamazwe (isb., u-Hill & Smith, Tata) abanweba ukufinyelela ngobudlelwano.

Emaphakathi Mpumalanga

Imigomo Yokusesha Yasendaweni

Imboni yemigwaqo emikhulu yaseMpumalanga Ephakathi ivame ukusebenza kuzo zombili IsiNgisi nesi-Arabhu, ngakho-ke amagama okusesha ayahlukahluka kuye ngokuthi umsebenzisi. Emazweni aseGulf, amagama ajwayelekile esiNgisi ahlanganisa "unogada", "umgoqo wokuphahlazeka", Futhi "umgoqo wokuphepha emgwaqeni." Ngesi-Arabhu, imishwana efana “حاجز سلامة الطرق” (hajiz salaamat al-turuq, okusho “umgoqo wokuphepha emgwaqeni”) noma “Hاجز طريق” (umgoqo womgwaqo) zisetshenziselwa ukubhekisa kuma- guardrail. Isibonelo, isikhulumi sesi-Arabhu singasesha “حاجز معدني للطرق” (umgoqo womgwaqo wensimbi). Empeleni, imibhalo eminingi yokuthengwa kwempahla yesifunda ingesiNgisi, ngakho-ke amagama anjengokuthi "I-W-beam guardrail" futhi "isithiyo sokuphahlazeka kwensimbi" ziyahlonishwa embonini. Amazwe afana ne-UAE, Qatar, kanye ne-Saudi Arabia anemiphakathi emikhulu yobunjiniyela abavela kwamanye amazwe, ngakho ukusesha kwesiNgisi “njengabahlinzeki be-highway guardrail UAE” noma “umgoqo wokuphahlazeka i-Saudi Arabia” kuvame kakhulu. ETurkey (okuvame ukufakwa kuhlaziyo lwaseMpumalanga Ephakathi), igama lendawo lithi "i-otomatik bariyer" or “ukwenza kahle kakhulu” (i-steel highway guardrail) ngesi-Turkish, nakuba izinkampani zaseTurkey nazo zisebenzisa ukumaketha kwesiNgisi. Sekukonke, amagama esiNgisi nawendabuko asetshenziswa: unjiniyela wezokwakha eMpumalanga Ephakathi angase asebenzise amagama obuchwepheshe esiNgisi, kuyilapho imibuzo evamile ingase isebenzise isi-Arabhu. Isifinyezo "W-beam" ngokwalo angeke lihunyushwe; Izincwajana zesi-Arabhu ngezinye izikhathi zivele zithi “W شعاع حاجز” (ngokwezwi nezwi elithi “W beam barrier”). Ngakho-ke, i-SEO yesifunda kanye nokusesha kuhlanganisa ingxube: i-guardrail, isithiyo sokuphahlazeka, umgoqo womgwaqo onguthelawayeka kanye nezinguqulo zesi-Arabhu ze-barrier and guardrail.

Isidingo Semakethe namathrendi

I-Middle East ibhekene nakho ukukhula okuqhubekayo kwesidingo oqaphe imigwaqo emikhulu, eqhutshwa izinhlelo ezibanzi zokuthuthukiswa kwemigwaqo kanye nokugcizelela ukuphepha emigwaqeni emazweni asathuthuka (Ucwaningo lweMakethe ye-Highway Guard Rails: Ucwaningo Olujulile lwango-2032). Amazwe amaningi kulesi sifunda atshala imali eningi kungqalasizinda njengengxenye yezinhlelo zentuthuko zesikhathi eside (isb., iSaudi Vision 2030, Qatar National Vision 2030, ukunwetshwa kwemigwaqo okuqhubekayo kwe-UAE). Imigwaqo emisha ewuthelawayeka, imigwaqo esheshayo, kanye nemigwaqo yasemadolobheni iyakhiwa kuwo wonke amazwe e-Gulf Cooperation Council (GCC), edinga izinkulungwane zamakhilomitha zezinsimbi ezintsha zokuqapha. Isibonelo, iSaudi Arabia inoxhaxha lwemigwaqo emikhulu kakhulu esifundeni (ngaphezu kuka-73,000 km wemigwaqo (Isu Lomkhakha Wezomgwaqo kanye Nohlelo Oluyinhloko - Saudi Arabia - ALG: Global)) futhi iqhubeka ngokungeza imizila esheshayo futhi ithuthukisa ekhona kakade, okuholela ekufakweni okubalulekile kwe- guardrail ezindaweni ezisanda kwakhiwa kanye namaphasishi athuthukisiwe. Ukulungiselela imicimbi esezingeni eliphezulu (njengeNdebe Yomhlaba ka-2022 e-Qatar) kanye namaphrojekthi amakhulu (i-Neom e-Saudi, amadolobha amasha, nezindawo zezimboni) nakho kunomthelela ekufuneni izithiyo zokuphepha zesimanje.

Ngaphandle kokwakhiwa okusha, ukugcinwa nokushintshwa izidingo ziyakhula. Izimo zezulu eziqinile zasogwadule (ukushisa okudlulele, izikhukhula ngezikhathi ezithile, nokuchayeka kwe-UV) kungaguga kuma-galvanized steel guardrails, futhi umonakalo wokushayisana ovamile ezindaweni ezinethrafikhi kudinga ukushintshwa kwezingxenye. Ohulumeni nabo baphakamisa izindinganiso zokuphepha - isibonelo, ukufaka I-Thrie-beam enezinhlangothi ezimbili ama-guardrails kuma-medians ukuvimbela izingozi eziphambanayo emigwaqweni enesivinini esikhulu, noma ukwengeza ukuvikelwa kwabashayeli emigomeni ekhona. Amanye amazwe aseMpumalanga Ephakathi aseqalile ukwamukela izindinganiso zamazwe ngamazwe (AASHTO M180 noma EN 1317) ngokusemthethweni, okusho ukuthi angase athuthukise imigoqo emidala esezingeni eliphansi ngokufanele.

IMpumalanga Ephakathi ithembele kakhulu imikhiqizo evela ngaphandle noma esungulwe endaweni kwezokugada. Kukhona ukukhiqizwa kwasekhaya okuncane kwamanye amazwe (ngaphandle okuphawulekayo eGulf). Kodwa-ke, izinkampani zasendaweni ezikhiqiza insimbi sezinyukile: e-UAE, e-Saudi Arabia, naseTurkey, abakhiqizi bakhiqiza ama-guardrails ahambisana nezindinganiso zamazwe ngamazwe ukuhlinzeka ngamaphrojekthi wasekhaya kanye namazwe angomakhelwane. Ukugeleza kwezohwebo kubonisa lokho Turkey kanye China bangabathengisi abakhulu be- guardrails esifundeni esibanzi saseMpumalanga Ephakathi, besebenzisa izinzuzo zezindleko. Isibonelo, ama-guardrails enziwe eTurkey asetshenziswe kumaphrojekthi e-Iraq nase-Saudi, futhi abahlinzeki baseShayina bavame ukubhida kumathenda ase-Afrika naseMpumalanga Ephakathi ahlinzeka ngokulethwa kwenqwaba eshibhile. Noma kunjalo, amazwe e-GCC athanda abakhiqizi bendawo noma besifunda be-Gulf ukulethwa okusheshayo nokuhambisana (ikakhulukazi njengoba ukuhambisa imishayo yensimbi emide kungabiza). Ngokwebhalansi, imakethe ye-Guardrail yaseMiddle East i growing, egqugquzelwa ingqalasizinda emisha nokuthuthukiswa kokuphepha, okuxube ukukhiqizwa kwasekhaya kanye nezinto eziphuma kwamanye amazwe ezihlangabezana nesidingo.

Izimbangi ezinkulu

Imikhiqizo emikhulu nabahlinzeki be-W-beam kanye ne-Thrie-beam guardrails e-Middle East bahlanganisa inhlanganisela abakhiqizi bendawo be-GCC, Izinkampani zaseTurkey, Futhi amafemu ngamazwe ngokusebenzisa abasabalalisi:

I-Link Middle East Ltd (LME) - (Iwebhusayithi: linkmiddleeast.com) Isekelwe e-UAE, i-Link Middle East ingumkhiqizi wesifunda ovelele wocingo kanye nezinhlelo zokuthibela imigwaqo. Bayakhiqiza amasistimu onogada onguthelawayeka ahambisana nawo womabili amazinga e-AASHTO M180 kanye ne-EN 1317, kanye nazo zonke izingxenye ezihlobene (okuthunyelwe, amabhulokhi e-spacer, izingxenye zokugcina) (Abahlinzeki Bezitimela Ezigadayo - Xhumanisa IMpumalanga Ephakathi - Osonkontileka Bocingo, Abahlinzeki beGabions, I-Gabions Steel Wire, Uthango Lwepherimitha E-UAE, Gabions, Izintambo, Ikhebula E-UAE). Lokhu kuthobela okukabili kuzivumela ukuthi zinikeze amaphrojekthi alandela ama-specs aseMelika noma aseYurophu - isimo esivamile eMpumalanga Ephakathi. I-LME ihlinzeke ngezinsimbi zokuqapha zemigwaqo emikhulu yase-UAE kanye nokuthunyelwa kwamanye amazwe kwezinye izifundazwe ze-GCC. Bagcizelela ukuthi ama-guardrails abo avivinywa ngokuphelele ngokwezinga lamazwe ngamazwe (Abahlinzeki Bezitimela Ezigadayo - Xhumanisa IMpumalanga Ephakathi - Osonkontileka Bocingo, Abahlinzeki beGabions, I-Gabions Steel Wire, Uthango Lwepherimitha E-UAE, Gabions, Izintambo, Ikhebula E-UAE). Xhumanisa isizinda sokukhiqiza sase-Middle East e-Dubai sisho izikhathi zokuhola ezimfushane e-Gulf. Amanani ayaqhudelana nesifunda; isibonelo, banganikela ~$600–$800 ngethani ye-Guardrail (imisebenzi yakudala) kuye ngezintengo zensimbi, ezihumusha cishe ku-$10–$20 imitha ngayinye ku-W-beam evamile (ngaphandle kwempahla nokufakwa). Banesikhundla esiqinile e-UAE futhi banophawu oluthenjwayo lwekhwalithi kumaphrojekthi endawo.
I-DANA Steel (DANA Group) - (Iwebhusayithi: danagroups.com) Umkhiqizi oqinisekisiwe we-ISO 9001 e-UAE, i-DANA Steel ikhiqiza Amasistimu kathayela we-W-beam (amagagasi amabili). kanye nokuthunyelwa ngaphandle kuyo yonke i-GCC nangale kwalokho (I-GuardRails & CrashBarriers | IQEMBU LE-DANA - Ukwengeza Inani Kuwoyela Nensimbi). Izinsimbi zokuqapha ze-DANA zenziwe ngensimbi ethambile (amabanga afana ne-S275JR) kanye nediphu eshisayo efakwe uthayela ukuze kuvikeleke ukugqwala. Banikeza ubude obujwayelekile obusebenzayo (3.2m, 3.81m, 4m, njll.) obunogqinsi olusukela ku-2.7–3.5 mm, olumesha imigqa yokuqapha ejwayelekile ye-AASHTO Class A/B (I-GuardRails & CrashBarriers | IQEMBU LE-DANA - Ukwengeza Inani Kuwoyela Nensimbi). I-DANA inikeza uhlelo olugcwele oluhlanganisa izigxobo zensimbi (imvamisa i-C-channel 150×75 mm) kanye nehadiwe. Baphakele abaningi amaphrojekthi ahlonishwayo kulo lonke elaseMpumalanga Ephakathi (I-GuardRails & CrashBarriers | IQEMBU LE-DANA - Ukwengeza Inani Kuwoyela Nensimbi), izimboni ezisezingeni eliphezulu e-UAE. Amanani avela ku-DANA ngokuvamile asekelwe ekucaphuneni; njengomhlahlandlela, bakhuluma ngokusebenzisa i-premium galvanized steel evela kubahlinzeki abathembekile futhi ugxile kwikhwalithi ngaphezu kwentengo ephansi (I-Top Metal Beam Crash Barrier Manufacturer kanye Nomphakeli - Utkarsh India). I-DANA isheshe yaba umbangi obalulekile emakethe ye-GCC guardrail ngenxa yekhono layo lokukhiqiza lesifunda kanye nokumaketha okusebenzayo.
I-Arabian Fence & Guardrail (isb, i-Aravali / Okunye) - Izinkampani eziningana, njenge I-Aravali Fence LLC eDubai, sebenza ngokukhethekile ama- guardrails okuphepha anesilinganiso sokuphahlazeka futhi uhlinzekele izidingo zephrojekthi yangokwezifiso (Umhlinzeki we-Safety Guardrails e-Dubai, Abu Dhabi, UAE | I-Aravali Fence). Lezi zinkampani ngokuvamile zingamahlumela noma ozakwethu bezinkampani zamaNdiya (i-Aravali ekuqaleni ingeyeNdiya) futhi zenza ama-W-beam guardrails endaweni. Basebenzisa amagama angukhiye afana nokuthi "umgoqo wokuphahlazeka" futhi basebenzela bobabili osonkontileka bokwakha namakhasimende kahulumeni. Nakuba zingezinkulu njenge-LME noma i-DANA, izinkampani ezinjalo zigcwalisa izimfuno ze-niche nama-oda amancane. Imikhiqizo yabo ihlangabezana nemibandela edingekayo futhi bavame ukuyifaka. Amanani kanye nesabelo semakethe salokhu kuncike kumaphrojekthi; bahlala bencintisana ngokusebenzisa abasebenzi abanezindleko eziphansi noma izinto ezitholakala eNdiya.
Abakhiqizi baseTurkey (isb., Körfez, Günsoy, Makim) - I-Turkey inemboni yensimbi eqinile kanye nabakhiqizi abambalwa be-Guardrail abathumela ngenkuthalo eMpumalanga Ephakathi. Izinkampani ezifana I-Körfez Transport (KÖRFZ), I-Eksen, i-Makim, ne-Otoyol ukukhiqiza ama-guardrails ku-EN 1317 futhi kuvame ukubhida kumaphrojekthi aseMpumalanga Ephakathi (kungaba ngokuqondile noma ngosonkontileka). Ama-guardrails aseTurkey ayaziwa ngokuthi kuqiza kahle futhi ahlangabezane nezindinganiso zamazwe ngamazwe, okuwenza akhange kumaphrojekthi amakhulu aseMpumalanga Ephakathi afuna ibhalansi yekhwalithi nenani. Isibonelo, umphakeli waseTurkey angase anikeze i-thrie-beam guardrail ngezindleko eziphansi kunabakhiqizi bendawo base-Gulf, ngisho nangemva kokuthunyelwa. Ukuba seduze kweTurkey kuvumela ukulethwa okusheshayo ngolwandle emachwebeni asendaweni. Ngenxa yalokhu, ama-brand aseTurkey athole ingxenye ephawulekayo yokuhlinzekwa kwe- guardrail kumaphrojekthi ezindaweni ezifana ne-Iraq, Jordan, kanye neNyakatho Afrika. Angase angabi nakho ukuqashelwa "kwegama lasekhaya" ku-GCC, kodwa aqashelwa embonini ngokuhlinzeka ngezinhlelo zokuvimbela insimbi emigwaqweni eminingi.
Abahlinzeki bamazwe ngamazwe (Global). - Izinkampani zomhlaba wonke ezifana I-Valtir/Trinity futhi Hill & Smith futhi ibe khona ngabasabalalisi baseMpumalanga Ephakathi. Isibonelo, imikhiqizo ye-Trinity Highway (amatheminali, izithiyo zekhebula) iyathengiswa eMpumalanga Ephakathi, futhi ngezinye izikhathi amaphaneli awo okuqapha angeniswa ngamaphrojekthi asekelwa yi-US noma amazinga e-ARAMCO e-Saudi. Ingal (uphawu lwase-Australia ngaphansi kwe-Valmont) luhlinzeke ngezinhlelo zalo zokuvikela zobunikazi nakwamanye amaphrojekthi aseMpumalanga Ephakathi. Lezi zinkampani ngokuvamile zisebenza ngama-ejenti wendawo, zihlinzeka ngemikhiqizo ye-premium (imvamisa yezinhlelo zokusebenza ezikhethekile njengezithiyo zokuqukethwe okuphezulu noma amakhushini okuphahlazeka). Isabelo sabo semakethe sincane uma siqhathaniswa nabakhiqizi bendawo/besifunda ukuze bathole ama- guardrail ajwayelekile, kodwa badlala indima ikakhulukazi uma iphrojekthi icacisa uhlelo oluthile lobunikazi.

Kubalulekile ukuphawula lokho ISaudi Arabia namanye amazwe e-GCC bebelokhu bekhuthaza okuqukethwe kwasendaweni. ESaudi, izinkampani ezinkulu zensimbi (isib. Ipayipi lensimbi laseSaudi or Zamil Steel) banekhono lokukhiqiza i- guardrail uma kudingeka, futhi kunemibiko yokukhiqizwa kwendawo kwamaphrojekthi athile. Kodwa-ke, okuningi kokuhlinzekwa kwe-Guardrail yaseSaudi kusavela ngaphandle noma emabhizinisini ahlanganyelwe. Isibonelo, amanye amaphrojekthi aseSaudi asetshenzisiwe Ama-guardrails enziwe eShayina ngenxa yamanani ancintisanayo (amafemu aseShayina avame ukufuna amanani amakhulu okuthekelisa, ngokukhangisa komkhiqizi oyedwa waseShayina 150,000 MT/umthamo wonyaka kanye nesabelo sokuthekelisa esingu-50% (I-Hot DIP Galvanized Highway Guardrail Thrie Beam Safe Road Barrier for Traffic Protection nge-CE Certificate - Hot-DIP Galvanized Highway Guardrail kanye ne-Beam Safe Highway Guardrail) (I-Hot DIP Galvanized Highway Guardrail Thrie Beam Safe Road Barrier for Traffic Protection nge-CE Certificate - Hot-DIP Galvanized Highway Guardrail kanye ne-Beam Safe Highway Guardrail)). Ngakho-ke imakethe yaseMpumalanga Ephakathi ibona a ingxube yemithombo, kodwa izimbangi eziyinhloko ezibalwe ngenhla ziphakathi kwalezo ezinobukhona besifunda obungaguquki.

i-South America

Imigomo Yokusesha Yasendaweni

ENingizimu Melika, amagama eSpanishi nesiPutukezi asetshenziswa ngokuyinhloko, eduze namagama athile esiNgisi ezobuchwepheshe ezimweni zamazwe ngamazwe. Emazweni akhuluma iSpanishi (iningi laseLatin America), amagama ajwayelekile ahlanganisa "Guardraíl" (ngokuqondile kusuka ujantshi wonogada) futhi "barrera de contención" (umgoqo wokuqukethwe) wemigwaqo egada umgwaqo omkhulu. Amanye amagama eSpanishi "Defensa metálica" (metal guard), noma kalula "Barrera de seguridad vial." I-Colloquial Chilean noma iSpanishi yase-Argentina ingase isebenzise "ujantshi wonogada" futhi, kunikezwe ithonya lesiNgisi, noma ngisho "quitamiedos" (njengaseSpain) enkulumweni engakahleleki. Ku Brazil, okuyisiPutukezi, amagama avamile "Defensa metálica" (efana neSpanishi) noma "unogada wesitimela e-rodovia." IsiPutukezi saseBrazil sivame ukusebenzisa igama lesiNgisi elithi “guard-rail” noma “guardrail” (elipelwa endaweni ngokuthi guardrail ngaphandle kwe-hyphen) ezimweni zobunjiniyela. Isibonelo, i-Brazilian spec ingase ikubize "defensa metálica tipo flexível" (i-flexible metal barrier) kodwa umphakathi jikelele kanye nosonkontileka bathi “guardrail”. Ukusesha ngeSpanishi eNingizimu Melika kuvame ukusetshenziswa "Guardarraíl carretera" or "barrera de contención autopista" ukuthola abahlinzeki. Ekuseshweni kwesiPutukezi, umuntu angabona "barreira de segurança viária" or "unogada wesitimela rodoviário." Sekukonke, igama lesiSpanishi i-guardraíl nesiPutukezi guardrail ziqondwa kabanzi. Abasebenzisi futhi basesha ngezindinganiso zendawo noma iziteketiso; isb, kwamanye amazwe i- guardrail iteketiswa "ibhande" or "i-flex beam" (ikakhulukazi uma kuthonywe uhlobo lwaseMelika olusebenzisa i-“Flexbeam” kwezokumaketha). Kodwa ngokuvamile, Isi-Spanish: “guardarraíl/barrera de contención” futhi IsiPutukezi: “guardrail/barreira de segurança” amagama angukhiye okuya kuwo.

Isidingo Semakethe namathrendi

Isidingo saseNingizimu Melika sezinsimbi zokugada emigwaqweni emikhulu siyehluka ngokwamazwe, sihambisana namazinga okuthuthukiswa kwengqalasizinda kanye nezinhlelo zokuphepha emgwaqeni. Isifunda siyabona ukukhula okumaphakathi ekufuneni i- guardrail njengoba umnotho utshala ingqalasizinda yezokuthutha (Ucwaningo lweMakethe ye-Highway Guard Rails: Ucwaningo Olujulile lwango-2032), nakuba amazinga okukhula asalela emuva kwe-Asia noma eMpumalanga Ephakathi. Izici ezibalulekile zifaka:

Utshalomali Lwengqalasizinda: Iminotho emikhulu njenge Brazil batshala imali emigwaqweni emikhulu ngokusebenzisa ubambiswano oluphakathi komphakathi nezizimele. Uhulumeni waseBrazil, ngokwesibonelo, ubelokhu ethandana 300 billion reais (~$62 billion) ekutshalweni kwezimali komgwaqo ozimele ngo-2026 (I-Brazil inezinkantolo ezingaphezu kwezigidigidi ezingama-60 zamarandi ekutshalweni kwezimali emigwaqweni emikhulu ngo-2026), okubandakanya imigwaqo ekhokhelwayo nokuthuthukiswa - konke okudinga imigoqo yokuphepha. Izivumelwano ezintsha zomgwaqo onguthelawayeka (isb., e-São Paulo, e-Minas Gerais) ngokuvamile zihlanganisa ukufakwa kwamamayela ezinqolobane zasemaphandleni kanye nokulungisa kabusha imigwaqo emidala ukuze ihlangabezane nezindinganiso zesimanje. Amanye amazwe, njengawo EColombia, ePeru naseChile, esekelwa amabhange okuthuthukisa (i-IDB, iBhange Lomhlaba), athuthukisa amaphaseji abalulekile (isb, imigwaqo emikhulu yezintaba, izingxenye ze-Pan-American Highway) futhi anezela imigwaqo yokuqapha lapho ingekho khona noma ithatha indawo emidala, engekho ezingeni (imigwaqo eminingi yasemaphandleni yaseLatin America ngokomlando yayingenazo izinsimbi zokuqapha, ngakho-ke kunesidingo sokulinda njengoba ukuphepha kuba yinto eza kuqala).
Ukuya emadolobheni kanye Nokuphepha Emgwaqeni: Ukukhula kwezimoto eNingizimu Melika ngeshwa kuza nezinga eliphezulu lezingozi zomgwaqo. Ohulumeni baya ngokuya begxila ekuphepheni emgwaqeni, okuhlanganisa ukufaka izinsimbi zokuqapha emajika ayingozi, izindlela zamabhuloho, nezihlukanisi ezimaphakathi. Izinhlelo emazweni afana I-Argentina neColombia ukunciphisa ukufa kwabantu emigwaqeni (Vision Cero kwamanye amadolobha, njll.) ngokuvamile kuvame ukufaka ukuthuthukiswa kokuvikelwa komgwaqo njengento yesenzo. Lokhu kuholela kumaphrojekthi okubuyisela emuva - isb, ukufakwa kwezithiyo ze-thrie-beam kuma-medians emigwaqo yasemadolobheni noma ukungeza ojantshi be-W-beam emigwaqeni emidala.
Isondlo kanye Nesimo Sezulu: Kwezinye izifunda, izinsimbi zokugada kufanele zishintshwe ngenxa yokugqwala (umoya kasawoti wasogwini ezindaweni ezifana nePeru elisogwini noma eChile ungagqwala insimbi) noma umonakalo. Isimo sezulu esinhlobonhlobo saseNingizimu Melika - ukusuka ezindaweni eziphakeme zase-Andean ezine-UV eyingozi kakhulu ukuya emvula enkulu yase-Amazon - sisho ukuthi ukufakwa kukagesi nokunakekelwa kubalulekile. Amazwe anezabelomali zokunakekela ezizinzile (njenge-Chile) anamashejuli avamile okushintsha i- guardrail, egcina isidingo samayunithi amasha minyaka yonke.

Ukunikezwa eNingizimu Melika kuyingxube ye ukukhiqizwa kwasekhaya kanye nokungeniswa kwamanye amazwe. I-Brazil, nemboni yayo ebalulekile yensimbi, inabakhiqizi abambalwa basekhaya abakhiqiza imigqa yokugada ukuze isetshenziswe ngaphakathi (ukuqinisekisa ukutholakala kwenethiwekhi yayo enkulu). Amazwe afana Argentina futhi Colombia babe nokukhiqizwa kwezikali ezincane noma bahlanganise izingxenye ezingenisiwe. Ngokuvamile, impahla evela eChina noma kwenye indawo vala izikhala, ikakhulukazi emazweni amancane noma lapho intengo ibalulekile. Isibonelo, izinkampani zaseShayina zithumele inqwaba yezinsimbi zokugada eNingizimu Melika, zisebenzisa izindleko eziphansi - amathenda amaningi okuthenga aseLatin America abona amabhidi aseShayina ahlinzeka ngemikhiqizo ehlangabezana ne-AASHTO noma izindinganiso zasendaweni ngamanani ahehayo.

Kubalulekile ukuqaphela ukuthi izindinganiso eNingizimu Melika ngokuvamile ziphuma ezinkambisweni zase-US noma zaseYurophu. Amazwe amaningi alandela i I-AASHTO M180 spec for guardrails (ngenxa yethonya lase-US kubunjiniyela baseLatin America). Abanye, ikakhulukazi labo abanethonya laseYurophu noma uxhaso, bangasebenzisa EN 1317 izigaba. Lokhu kukhinyabeza isidingo sokuthi ngezinye izikhathi kufunelwa izinsimbi zokuqapha eziphakeme kakhulu (ezishubile, eziphakeme) kumaphrojekthi athile. Sekukonke, isidingo semakethe eNingizimu Melika sinjalo kumkhuba okhuphukayo kodwa hhayi njengokuqhuma njengasezifundeni ezithola ukwakhiwa kwenethiwekhi entsha sha. Iqhutshwa yingxubevange yamamayela othelawayeka amasha anezelwayo (isibonelo, izandiso zemigwaqo emikhulu yamazwe ngamazwe noma imigwaqo ekhokhelwayo emisha) kanye nokucindezela kokuthuthukisa ukuphepha emigwaqweni ekhona.

Izimbangi ezinkulu

Imakethe ye-Guardrail yaseNingizimu Melika ihlanganisa inhlanganisela ye abakhiqizi bendawo emazweni amakhulu futhi abahlinzeki bamazwe ngamazwe (ngokungenisa impahla noma amagatsha endawo). Amaphuzu avelele esiqhudelana nawo afaka:

I-Segurvia (Brazil) – (Iwebhusayithi: segurvia.com.br) I-Segurvia yinkampani yaseBrazil eyi- umholi emigomeni yezokuphepha emgwaqeni eBrazil (I-Inicio - Segurvia). Bagxila kakhulu kuzithiyo zikakhonkolo (uhlobo lwaseNew Jersey) njengoba kukhonjiswa imigqa yomkhiqizo wabo (I-Inicio - Segurvia), kodwa futhi bahileleke ekuqapheni insimbi (imvamisa ukwenza inkontileka encane noma ukubambisana kwezingxenye zensimbi). Ukuvelela kwe-Segurvia emakethe ye-barrier yase-Brazil kusho ukuthi lapho insimbi yokugada idingeka, ingaxhumanisa ukunikezwa/ukufakwa. Baqhosha ngemininingwane efana namakhulu amakhilomitha ezithiyo ezifakwe emigwaqweni emikhulu eBrazil (I-Inicio - Segurvia). Nakuba i-Segurvia ngokwayo ingase ingakhiqizi isitimela se-W-beam ngensimbi engaphekiwe, iyisifaki esikhulu futhi ngaleyo ndlela iqhudelane namabhidi, ithole izinsimbi zokugada kozakwethu bensimbi. Ukuma kwemakethe: okuhamba phambili emakethe yasekhaya yaseBrazil ngezithiyo zomgwaqo omkhulu, okungenzeka ukuphatha a ingxenye enkulu yokufakwa kwesithiyo somgwaqo omkhulu (noma ngabe insimbi noma ukhonkolo) e-Brazil.
I-Talleres y Aceros SA (TyASA) - Izinze eMexico kodwa ezisebenzela iLatin America, iTyASA (noma izinkampani ezifanayo ezifana nazo Iqembu Collado eMexico) khiqiza I-AASHTO-spec guardrails ezithunyelwa ezifundeni ezingomakhelwane. I-Mexico, nakuba iseNyakatho Melika, ivame ukusebenzela izidingo zaseLatin America ngenxa yobudlelwano bendawo kanye nezohwebo. I-TyASA inomshini omkhulu wensimbi futhi yenza amaphaneli e-W-beam nezigxobo, ihlinzeka ngamaphrojekthi eMelika Ephakathi neseNingizimu. Isibonelo, bahlinzeke ngonogada kumaphrojekthi e-Colombia nasePeru. Intengo evela kubahlinzeki base-Mexico ingaba nenzuzo ngenxa yokugeleza kwensimbi ye-NAFTA/USMCA. Abaqaphi be-TyASA bahlangabezana nezindinganiso zase-US futhi babekwe njengabahlinzeki bekhwalithi. Nakuba bengezona "indawo" eNingizimu Melika, bangabaqhudelani bangaphandle abaphawulekayo abasebenzela imakethe yesiLatini.
Izinkampani Zensimbi Zasendaweni (i-Brazil & Argentina) - Izinkampani ezifana UGerdau or Usiminas eBrazil, futhi mhlawumbe I-Acindar (ArcelorMittal) e-Argentina, khiqiza insimbi engakhiwa ibe yizinsimbi zokuqapha. EBrazil, I-Industrias Metálicas futhi abanye bakha imishayo yokugada ukuze banikeze iminyango yemigwaqo emikhulu kahulumeni. Isibonelo, ngokomlando i-Brazil yayine-“Armco Staco” eyayikhiqiza imikhiqizo kathayela (igama elithi “Armco” lalikhona ngokomlando embonini yase-Brazil). Laba bakhiqizi bendawo bavame ukuhlinzeka ngamaphrojekthi angaphakathi kwezwe ngokukhethayo. Ngakho imakethe yaseBrazil inesici sokuzethemba; umuntu angalinganisela ukuthi abakhiqizi baseBrazil banengxenye enkulu yesabelo sasekhaya. E-Argentina naseChile, ezinye izinto eziqanjiwe zisendaweni kodwa hhayi ngezinga elikhulu; ngakho-ke bathembele kakhulu ekuthengisweni kwamanye amazwe kumaphrojekthi amakhulu.
Abathekelisi baseShayina - Izinkampani eziningi zaseShayina zingenele ngokuthumela ama-guardrails eNingizimu Melika. Ngokuvamile zisebenza ngezinkampani ezihwebayo noma ngamabhidi aqondile kumathenda amazwe ngamazwe. Isibonelo, umuntu angathola okunikezwayo ku-Alibaba noma ngamathenda lapho amafemu aseShayina ecaphuna khona insimbi yokugada ngo-$10–$20 ngonyawo ububanzi (Ibiza Malini I-Highway Guardrail? Umhlahlandlela ophelele), ehlisa izintengo zendawo. Abanye abathekelisi abaziwayo (njengoba bekhangisiwe) bahlanganisa HuaAn Ama-Guardrails, I-Shandong Zhonghua Metal, njll., ehlinzeka ngomhlangano kajantshi we-ASTM A123 wokuvuza kanye ne-AASHTO M180 Ikilasi A/B. Kubikwa ukuthi abahlinzeki baseShayina balethe imiqulu emikhulu yamaphrojekthi wemigwaqo emikhulu emazweni afana I-Ecuador, iBolivia, nePeru, lapho izingqinamba zesabelomali zivuna ukutholakala kwezindleko eziphansi. Isabelo sabo semakethe eNingizimu Melika siyakhula engxenyeni ye-commodity guardrail, nakuba imisebenzi kanye nemisebenzi yokungenisa ezweni ingaba yisici esikhawulelayo.
Imikhiqizo ye-Trinity Highway (Valtir) - I-Trinity (US) ngokomlando yayinendawo yokukhiqiza I-Mexico (Monterrey ne-Tlaxcala) futhi isabalalise imikhiqizo eLatin America. Isibonelo, i-Trinity's ET-Plus nezinye iziphetho zisetshenziswe eMexico naseBrazil. I-Trinity/Valtir ngezinye izikhathi inikeza ngokuqondile ama- guardrail amaphrojekthi axhaswe yi-US noma idayise ngamafemu okwakha endawo. Nakuba i-Trinity ingase ingabi nayo imboni eNingizimu Melika, ukusebenza kwabo eNyakatho Melika (futhi mhlawumbe nokubambisana) kuyabavumela ukuba baqhudelane kumaphrojekthi amakhulu. Uma kubhekwa izinga labo lomhlaba wonke, uZiqu-zintathu uyabonakala futhi wabo “Umgwaqo Omkhulu Kathathu” ama-brand guardrails (noma ama-generic rails plus proprietary terminals) anocezu lwemakethe, ikakhulukazi emazweni asondelene kakhulu nezindinganiso zase-US.

Ngaphezu kwalokho, Abahlinzeki baseYurophu ngezikhathi ezithile iqhaza kumaphrojekthi aseNingizimu Melika, ikakhulukazi lawo axhaswe ngemali yaseYurophu. Ngokwesibonelo, I-Hierros y Aplainados yaseSpain or I-Marcegaglia yase-Italy ingase ikhiphe ama- guardrail emisebenzi ethile. Kodwa-ke, izindleko zokuthumela eziphakeme kanye nezikhathi zokuhola ezinde ngokuvamile zenza imithombo yendawo noma yesifunda ikhange kakhulu.

Kafushane, ayikho inkampani eyodwa ebusa iNingizimu Melika; yinkundla yokuncintisana nge Abakhiqizi baseBrazil nabaseMexico ukubhekelela izidingo zasekhaya nezesifunda, kanye Abahlinzeki baseShayina nabamazwe ngamazwe umncintiswano wokujova. Singaveza iBrazil njengezinto ezizihlinzeka ngokwazo (nezinkampani ezinjengeSegurvia, i-Armco Staco ngokomlando, njll.), i Amazwe ase-Andean kanye nezimakethe ezincane njengokuthembela kokungenisa, nezindawo ezinjengalezi Chile ukuba nebhalansi (i-Chile ivamise ukuthenga ngama-ejenti endawo angase angenise emithonjeni eminingi). Imakethe nayo ayizwani nentengo, yingakho ukuthengwa kwamanye amazwe kubakhiqizi ababiza kancane kunethonya.

(Ukuthengwa kwe-guardrail yaseNingizimu Melika kuvame ukuya kosonkontileka bokwakha. Laba sonkontileka bavela kubahlinzeki abangenhla ngokusekelwe ezindlekweni nokuhambisana nemibandela ethile. Ngakho, isabelo semakethe singahlukaniswa. IBrazil iyodwa ibamba ingxenye enkulu yesidingo sesifunda futhi inenethiwekhi yangaphakathi yokuhlinzeka, kuyilapho amazwe ethanda Colombia, Peru, Chile, Argentina bona ingxube yezinto ezithengwayo kanye nokukhiqizwa kwasendaweni okulinganiselwe. Sekukonke, ukuncintisana kuqhutshwa izindleko, ngekhwalithi eqinisekisiwe njengemfuneko enikeziwe.)

Asia Pacific

Imigomo Yokusesha Yasendaweni

Isifunda sase-Asia Pacific sihlanganisa izilimi nezimakethe eziningi, ngakho-ke amagama okusesha ama-guardrails ahluka kakhulu:

China: NgesiShayina, i-W-beam guardrail ibizwa ngokujwayelekile “波形护栏” (bōxíng hùlán, okusho ukuthi “umzila wokugada omise okwegagasi”) noma “波形梁护栏” (“i-wave-beam guardrail). Onjiniyela baseShayina bayasebenzisa “高速公路护栏” (highway guardrail) ekusesheni. Isibonelo, othile e-China angasesha “波形护栏厂家” (umkhiqizi we-wave guardrail) lapho etholakala. Igama “护栏板” (iphaneli ye-Guardrail) isetshenziselwa izinsimbi zensimbi ngokwazo (高速公路护栏板/波形梁钢护栏 – 型钢). I-Thrie-beam guardrails ingachazwa ngokuthi “三波护栏” (i-wave-wave guardrail) ngesi-Chinese.
India: IsiNgisi sivame kakhulu emikhakheni yezobuchwepheshe, ngakho-ke amagama afana nalokhu "isithiyo sokuphahlazeka kwensimbi" zisezingeni. Eqinisweni, i-Indian Roads Congress kanye ne-Ministry of Road Transport basebenzisa leli gama “I-Metal Beam Crash Barrier (MBCB)” ye-W-beam guardrails ngokucaciswa. Abasebenzisi baseNdiya basesha "abahlinzeki besithiyo sokuphahlazeka", “Isithiyo sokuphahlazeka se-W-beam”, noma kumane "i-Guardrail India." Ngesi-Hindi noma kwezinye izilimi zendawo, alikho igama lendabuko elisetshenziswa kakhulu; IsiNgisi esithi “crash barrier” noma “guardrail” sivame ukuqondwa.
Japan: Izwi "ガードレール" (gādorēru, ukuguqulwa kwamaletha kokuthi guardrail) igama elijwayelekile. I-thrie-beam ingabizwa "3波ガードレール" (3-wave guardrail). Usesho lwama-Japanese lungaba "ガードレールメーカー" (umkhiqizi we-Guardrail).
Korea: Isebenzisa okufanayo "가드레일" (i-gadeureil kusuka ku-guardrail). Ukusesha kungase kuhlanganise “도로 안전 가드레일” (unogada emgwaqeni).
Southeast Asia: Emazweni afana Indonesia futhi Malaysia, amagama endawo akhona (isi-Indonesian: "pagar pengaman jalan raya", isi-Malaysian: "indawo yokugezela"), kodwa ngokuvamile isiNgisi esithi “guardrail” noma “isithiyo somgwaqo” sisetshenziswa embonini. Ku Thailand, igama “ราวกันอันตราย” (isitimela sokuphepha emgwaqeni) sisetshenziswa kuzinkomba zobuchwepheshe, kodwa abahlinzeki abaningi basebenzisa amagama esiNgisi.
I-Australia / New Zealand: Kusetshenziswa isiNgisi; amagama ajwayelekile "unogada", "I-W-beam guardrail", noma kumane “umgoqo wokuphepha.” I-Australia nayo isebenzisa leli gama "unogada" kumazinga (amazinga e-AS/NZS abhekisela ku-W-beam guardrail njengothango lonogada). Igama lomkhiqizo "Armco" isetshenziswa ngokungakahleleki e-Australia kanye nasezindaweni zokugada insimbi. Ngakho-ke umuntu wase-Australia angasesha "Abahlinzeki besitimela be-Armco" or “W-beam guardrail AS1906”.

E-Asia Pacific yonkana, isiNgisi sisebenza njengolimi olusetshenziswa kakhulu kwezobunjiniyela, amagama afana nalawa "I-W-beam guardrail," "umgoqo wokuphahlazeka," futhi “umgoqo wokuphepha” izobonakala emazweni amaningi. Nokho, amagama olimi lwendawo (isiShayina, isiJapane, njll.) abaluleke ngokulinganayo ekusesheni kwasekhaya. Isibonelo, umbuzo we "i-highway guardrail" ngesiShayina nakanjani izosebenzisa izinhlamvu zesiShayina. Kafushane, usesho lwase-Asia Pacific lusukela ukuguqulwa kwamaletha (ガードレール, 가드레일) kuya izinguqulo (波形护栏) ukwenza isiNgisi esilula, kuye ngendawo.

Isidingo Semakethe namathrendi

I-Asia Pacific imele imakethe enkulukazi nekhula ngokushesha konogada bomgwaqo omkhulu emhlabeni (Ucwaningo lweMakethe ye-Highway Guard Rails: Ucwaningo Olujulile lwango-2032). Kunezici ezimbalwa ezinomthelela ekufuneni okukhulu:

Ingqalasizinda Enkulu YaseChina: I-China yakhe inethiwekhi yomzila wesitimela enwetshiwe (>160,000 km futhi ekhulayo), yonke ifakwe ama-W-beam guardrails nhlangothi zombili kanye nama-medians. Noma ngabe ukwakhiwa komgwaqo omkhulu kuhamba kancane, ukugcinwa nokushintshwa izidingo zinkulu uma kubhekwa isikali. Ukwengeza, iShayina iyaqhubeka nokwengeza imigwaqo emikhulu emisha nakuba ihamba ngesivinini esilinganiselwe; ikhilomitha ngalinye elisha ngokuvamile lidinga u-2–4 km we- guardrail (zombili izinhlangothi, ngezinye izikhathi ezikabili emaceleni aphakathi). I-China iphinde ithumele inqwaba yezinsimbi zokugada: Abakhiqizi baseShayina bebonke bakhiqiza amakhulu ezinkulungwane zamathani ngonyaka, hhayi nje ukusetshenziswa ekhaya kodwa nokuthekelisa. Ukuze uthole umbono, ifekthri eyodwa enkulu yase-Chinese guardrail iyakhangisa 150,000 metric tons/umthamo wonyaka (I-Hot DIP Galvanized Highway Guardrail Thrie Beam Safe Road Barrier for Traffic Protection nge-CE Certificate - Hot-DIP Galvanized Highway Guardrail kanye ne-Beam Safe Highway Guardrail), futhi kunenqwaba yezimboni ezinjalo. Izindinganiso zasekhaya zaseShayina (JT/T 281) zihambisana nezinkambiso zamazwe ngamazwe, kanye nezithuthukisi eziqhubekayo zikahulumeni zokuphepha emigwaqweni enguthelawayeka (njengokuthuthukisa imigwaqo yasemaphandleni enezinsimbi ezigadayo ngaphansi kwendlela ye-Safe Systems) kugcina isidingo sendawo siqinile.
Ukwandiswa komgwaqo omkhulu waseNdiya: I-India iphakathi nohlelo olunolaka lokuthuthukisa umgwaqo omkhulu (isb., iphrojekthi ye-Bharatmala), yakha amashumi ezinkulungwane zamakhilomitha emigwaqo emisha nemigwaqo emikhulu. Lokhu kuholele ekwenyukeni kwesidingo sezinto izithiyo zokuphahlazeka kwensimbi yensimbi emigwaqweni emikhulu kazwelonke emisha. Umnyango Wezokuthutha Emgwaqeni & Nothelawayeka ugunyaze ukuthi kube nemigwaqo yokuqapha ezindaweni eziningi ezibucayi, futhi izifundazwe zase-India zilungisa kabusha izindawo eziyingozi ngezinsimbi zokuqapha. Imigwaqo emikhulu yaseNdiya ivame ukusebenzisa i MBCB (W-beam) guardrail njengesithiyo esijwayelekile somgwaqo; ngakho yonke inkontileka yomgwaqo entsha ihlanganisa amakhilomitha okufakwa kwe-guardrail. Ngohlelo lwase-India lokwengeza nokuthuthukisa imigwaqo emikhulu engu-65,000+ km, imakethe ye-Guardrail isemgudwini wokukhula oqinile. Ukwengeza, ukukhiqizwa kwasendaweni eNdiya kuyakhuphuka ukuze kuhlangatshezwane nalesi sidingo (ukunciphisa ukuthembela ekuthengeni kwamanye amazwe).
Iminotho Ekhulayo Yase-ASEAN: Amazwe afana I-Indonesia, iVietnam, iPhilippines, neThailand zandisa uxhaxha lwemigwaqo nemigwaqo. Isibonelo, i-Trans-Java yase-Indonesia kanye nemigwaqo ekhokhelwayo yase-Sumatra idinga ama-guardrails abanzi; Amaphrojekthi we-North-South Expressway yaseVietnam ngokufanayo ahlanganisa ukufakwa kwe-guardrail ukuze kuhlangatshezwane namazinga okuphepha. Lawa mazwe ngokuvamile athola ama- guardrail ngosonkontileka abangenisa kwamanye amazwe besuka kubahlinzeki besifunda (i-China, Malaysia, noma i-India) uma ukukhiqizwa kwendawo kukhawulelwe. Njengoba lezi zizwe zigcizelela ukuphepha emgwaqeni, ngisho nemigwaqo ekhona (njengothelawayeka wasezintabeni e-Vietnam noma imigwaqo emazombezombe e-Indonesia) ithola izivikelo ngaphansi kwezinhlelo zokuphepha.
I-APAC ethuthukisiwe: Ezimakethe ezithuthukile njenge Japan, South Korea, Australia, New Zealand, isidingo sizinzile, siqhutshwa ukugcinwa nokuthuthukiswa ngezikhathi ezithile. I-Japan ne-Korea inamanethiwekhi avuthiwe; bashintsha ama- guardrail amadala bafake imiklamo ethuthukisiwe (isb., ukwengeza ama-rub-rails okuvikela izithuthuthu noma ukusebenzisa imishayo emithathu ewugqinsi ezindaweni eziyingozi). I-Australia kanye ne-NZ babuyekeza ama-guardrails ukuze athobelane namazinga wakamuva wokuphahlazeka (MASH). Lawa mazwe aphinde ahlole ama-coatings (i-Japan isebenzisa ama-guardrails apendwe amhlophe amaningi ukuze enze ubuhle nokuvikela ukugqwala ezindaweni zasemaphandleni) okungaba nomthelela emijikelezweni yokushintshanisa. Isidingo lapha akukhona ukukhula okuphezulu, kodwa ingxenye yeprimiyamu (ama-spec guardrail aphezulu, ama-coatings akhethekile) ibalulekile.

Omunye umkhuba e-Asia Pacific kuyinto thekelisa umumo wezindawo zokukhiqiza. China futhi India akubona abathengi abakhulu kuphela kodwa futhi nabathumela ngaphandle (i-China ngaphezulu). Malaysia futhi Thailand zibe nokukhiqiza okuthile (ngokuvamile ngokusebenzisa izinkampani ezingaphansi kwezinkampani zase-Australia noma zaseJapane) futhi zithekelise ngaphakathi kwe-SE Asia. Australia ngokusebenzisa ukuthunyelwa kwe-Ingal/Valmont ezimakethe eziseduze (isb, ukuhlinzeka ngeziqhingi zase-Pacific noma i-SE Asia kumaphrojekthi lapho kusetshenziswa khona izici zaseNtshonalanga). Lokhu kwenza i-Asia Pacific ibe inetha isifunda sokuthekelisa zokuqapha, ikakhulukazi ukukhonza i-Afrika kanye neMpumalanga Ephakathi.

Ukutshalwa kwengqalasizinda kulo lonke elase-Asia Pacific kuhlala kuphezulu kakhulu, ikakhulukazi emigwaqweni yamazwe asathuthuka. Ukusetshenziswa kwemali kukahulumeni kuhlanganiswe nemalimboleko yebhange lentuthuko kuqinisekisa imiyalo eqhubekayo yokuqapha. Ngokwesibonelo, abaningi I-ADB (Asian Development Bank) or Ibhange Lomhlaba amaphrojekthi wemigwaqo e-Southeast Asia naseNingizimu-mpumalanga ye-Asia afaka phakathi imigqa yesabelomali yama- guardrails. Ngakho-ke, imakethe yase-Asia Pacific guardrail ayigcini nje ngokuba nkulu ngevolumu kodwa futhi ingenye yeziningi kakhulu ashukumisayo, ngokukhiqizwa kwevolumu ephezulu, ukuncintisana kwamanani, kanye nokusungula izinto ezintsha (ezinye izinkampani zaseShayina zethula ama-guardrails ane-polymer-coated, futhi amafemu aseJapane ahlole ama-Guardrails anezinzwa ezihlakaniphile, njll.).

Izimbangi ezinkulu

Imboni yokugada yase-Asia Pacific inkulu, kusukela kubakhi bempahla abancane kuya ezinkampanini ezinkulu zensimbi. Izimbangi ezibalulekile ngendawo engaphansi:

Abakhiqizi baseShayina (abahlukahlukene) – China has abakhiqizi abaningi abakhulu okunikezelwe ku-highway guardrails. Izibonelo zihlanganisa Hebei Huiyuan, Shandong Guanxian Huaan Traffic, Wuhan Dachu. Lezi zinkampani zisebenza ngokukhethekile kuma-W-beam kanye ne-Thrie-beam guardrails, ngokuvamile anezindawo zazo zokugalela ama-galvanizing. Ngokuvamile bahlinzeka ngohlu oluphelele lwemikhiqizo: imishayo yensimbi (kubo bonke ubude obujwayelekile obufana no-4320 mm okuwubude obuvamile obungu-12'6” (I-Hot DIP Galvanized Highway Guardrail Thrie Beam Safe Road Barrier for Traffic Protection nge-CE Certificate - Hot-DIP Galvanized Highway Guardrail kanye ne-Beam Safe Highway Guardrail)), amagalani noma ngezinye izikhathi ambozwe ngempushana, kanye nezigxobo zensimbi (isiteshi esingu-C noma i-I-beam), ama-spacers, amabhawodi, namatheminali okugcina (okujwayelekile, okunye okuphathelene). Izitimela zaseShayina zenziwa ngokwezindinganiso zamazwe ngamazwe - zicaphuna ukuthobela I-AASHTO M180, EN 1317, AS/NZS 3845, njll emibhalweni (I-Hot DIP Galvanized Highway Guardrail Thrie Beam Safe Road Barrier for Traffic Protection nge-CE Certificate - Hot-DIP Galvanized Highway Guardrail kanye ne-Beam Safe Highway Guardrail) (I-Hot DIP Galvanized Highway Guardrail Thrie Beam Safe Road Barrier for Traffic Protection nge-CE Certificate - Hot-DIP Galvanized Highway Guardrail kanye ne-Beam Safe Highway Guardrail). Abaningi banamandla amakhulu okukhiqiza; Ngokwesibonelo, HuaAn Traffic ikhombisa i-150k MT/ngonyaka kanye nesitifiketi esijwayelekile (I-Hot DIP Galvanized Highway Guardrail Thrie Beam Safe Road Barrier for Traffic Protection nge-CE Certificate - Hot-DIP Galvanized Highway Guardrail kanye ne-Beam Safe Highway Guardrail) (I-Hot DIP Galvanized Highway Guardrail Thrie Beam Safe Road Barrier for Traffic Protection nge-CE Certificate - Hot-DIP Galvanized Highway Guardrail kanye ne-Beam Safe Highway Guardrail). Amanani avela e-China anolaka kakhulu, athuthukisa umnotho wesilinganiso kanye nezindleko eziphansi zabasebenzi. Abahlinzeki baseShayina bebonke balawula imakethe yokuthekelisa futhi bafeza nesidingo sangaphakathi saseChina. Ngaphakathi, imakethe ihlukene phakathi phakathi kwabakhiqizi abaningi, kodwa wonke amaphrojekthi wemigwaqo emikhulu ahlinzekwa yileli phuli. Akuvamile lokho ngaphezu kwama-50% okukhiqizwa komkhiqizi waseShayina athunyelwa ngaphandle (美标波形护栏与国标的区别点 – 百度经验), okubonisa indlela abanethonya ngayo emhlabeni wonke. Ayikho inkampani eyodwa yaseShayina engakhonjwa “njengomholi” ngenxa yobuningi bayo, kodwa njengeqembu, abakhiqizi baseShayina umthombo omkhulu emhlabeni ye-W-beam guardrails ngevolumu.
Abakhiqizi BamaNdiya (isb., Utkarsh, Tata Steel Processing) – Ukukhiqizwa kwe-guardrail yaseNdiya sekudlondlobele ngezinhlelo zayo zemigwaqo. Utkarsh India iyisibonelo esiphawulekayo, ezibeka uphawu njengomkhiqizi ohamba phambili wezithiyo zokuphahlazeka kwensimbi eNdiya. I-Utkarsh ikhiqiza I-W-Beam kanye ne-Thrie-Beam yokuqapha, okuhlanganisa ojantshi bakathayela kanye nezingubo ezihlukahlukene, ukunamathela kuzo zombili izindinganiso zaseNdiya (ezibukisa nge-AASHTO M180) kanye nezindinganiso zamazwe ngamazwe (I-Top Metal Beam Crash Barrier Manufacturer kanye Nomphakeli - Utkarsh India). Bagcizelela insimbi yezinga eliphezulu (etholakala kwaTata Steel kanye neSAIL) (Umkhiqizi Nomhlinzeki Ophezulu Wokuphahlazeka Kwensimbi Yensimbi) futhi imikhiqizo yabo isetshenziswa kumaphrojekthi womgwaqo omkhulu kulo lonke elaseNdiya (I-Top Metal Beam Crash Barrier Manufacturer kanye Nomphakeli - Utkarsh India). Tata Steel ibuye ibe khona: Isikhungo se-Tata's Steelp**ark (njengoba kuphawulwe ezihlokweni ze-LinkedIn) sakha imigoqo yokuphepha emgwaqeni onguthelawayeka, futhi uhlelo lukaTata lwe-“Vetex” olusuka e-Europe lungase ludlulisele ulwazi e-India. Abanye abadlali baseNdiya bahlanganisa Rajdeep Metals, Omkareshwar, RR Onjiniyela, njll., ivamise ukuhlangana eduze kwamahabhu ezimoto/ensimbi. Abakhiqizi baseNdiya bahloselwe ikakhulukazi isidingo sasekhaya, kodwa abanye (njenge-Utkarsh) baphinde bathumele emazweni angomakhelwane (Bangladesh, Nepal, njll.). Uma kubhekwa izinga laseNdiya, lezi zinkampani zinomphumela omkhulu. Isikhundla semakethe: Abakhiqizi baseNdiya njengamanje bahlinzeka ngenqwaba yezidingo zaseNdiya (ukuthengwa kwempahla kuncane manje ngenxa yezinqubomgomo ze-Make-in-India), futhi bancintisana emazweni ngamazwe, nakuba bengakadlali njengamaShayina ekuthengisweni kwamanye amazwe. I-Utkarsh India, ngokwesibonelo, iyaziqhenya ngayo imikhiqizo ehlolwe ukuphahlazeka nokubambelela kumazinga omhlaba ukuncintisana ngale kweNdiya (I-Top Metal Beam Crash Barrier Manufacturer kanye Nomphakeli - Utkarsh India).
I-Ingal Civil Products (Valmont) – (Iwebhusayithi: ingalcivil.com.au) Isekelwe e-Australia, i-Ingal (ingxenye ye-Valmont Industries) umkhiqizi ohamba phambili e-Australia/New Zealand kanye nomkhiqizi ovelele e-Asia-Pacific (I-Ingal Civil Products - LinkedIn). I-Ingal ikhiqiza i-Australian public guardrail guardrail (i-w-beam guardrail enephrofayili ethile kanye nephethini yembobo kumazinga e-AS/NZS) kanye namasistimu obunikazi afana ne-Ezy-Guard (uhlelo lokuqapha olulungisiwe olunamaposi ambalwa). Baphinde basabalalise amakhushini ahlukene okuphahlazeka kanye nezithiyo zezintambo zezintambo. I-Ingal Civil ithi "Ochwepheshe bezivimbelo zokuphepha emigwaqweni emikhulu e-Asia Pacific." ( Ikhaya ). Banokukhiqiza e-Australia kanye nezinkampani ezingaphansi noma abanamalayisense eMalaysia (Ingal Malaysia) (Ingal Ezy-Guard) nezinye izindawo. Isabelo semakethe sika-Ingal e-Australia/NZ siphezulu kakhulu (sihlinzeka ngamaphrojekthi amaningi weziphathimandla zemigwaqo yesifundazwe). Emazweni ngamazwe, njengengxenye ye-Valmont, ngezinye izikhathi bawina amaphrojekthi eNingizimu-mpumalanga ye-Asia noma eMpumalanga Ephakathi lapho imiklamo yabo icaciswa khona. Intengo ye-Ingal's guardrail emakethe yayo yasekhaya iphakeme (ngenxa yezindleko zokukhiqiza zase-Australia) - cishe AUD $50–$80 imitha ojantshi abajwayelekile (izinto kuphela). Kodwa-ke, ukugxila kwabo kuyikhwalithi nokuhambisana nezindinganiso zakamuva zokuphahlazeka (MASH). Ngakho-ke i-Ingal/Valmont ibambe isikhundla esiqinile ngokwesifunda futhi isebenza njengophawu oluphambili e-Asia Pacific.
I-Nippon Steel & Sumitomo Metal (kanye nezinye izinkampani zaseJapan) - E-Japan, ama-guardrails ahlinzekwa izinkampani zensimbi zasekhaya noma izigaba zazo zokwenziwa. I-Nippon Steel, i-JFE Steel, njll., yenza amakhoyili ensimbi futhi ngokuvamile yenza ama- guardrails azosetshenziswa ekhaya. Ukwengeza, izinkampani ezikhethekile zaseJapane zithanda I-Yodogawa Steel Works khiqiza ama-guardrails, okuhlanganisa anemibala futhi aboshwe. Lezi zinkampani azivamile ukuthekelisa ngaphandle ngenxa yezindleko eziphezulu, kodwa zihlinzeka ngokuphelele ngezidingo zasendaweni. Imakethe yaseJapan iphethwe ngempumelelo ngabakhiqizi bayo basekhaya abahambisana nezinkampani zokwakha. ISouth Korea iyafana: izinkampani zithanda Insimbi ye-YK kanti abanye bahlinzeka ngemakethe yendawo. Laba abanabo ubukhona bamazwe ngamazwe kodwa bangabaqhudelani abakhulu emazweni abo (abanodlame kwezinye izimo ngenxa yamazinga nezinqubo zokuthenga).
Southeast Asian Fabricators - Inani labakhiqizi abancane bakhona eNingizimu-mpumalanga ye-Asia. Ngokwesibonelo, Malaysia inamafemu afana Izindleko zamasheya Astro Holdings or UAC akha ama-guardrails (ngezinye izikhathi ngaphansi kwelayisensi noma ngensimbi evela kwamanye amazwe). ThailandUmnyango womgwaqo onguthelawayeka kwesinye isikhathi uthola ama-guardrails enziwe izinkampani zendawo zensimbi e-Thailand. Vietnam isiqala ukwakha ama-guardrails ekhaya ukuze inikeze amaphrojekthi ayo omgwaqo omkhulu, ngokuvamile ngokubambisana kwama-Japanese noma ama-Korean. Laba badlali bakhonze kakhulu izimakethe zabo zasekhaya futhi kwesinye isikhathi amazwe angomakhelwane. Bavame ukuncintisana ngokulethwa okusheshayo nokujwayelana nemininingwane yendawo.

E-Asia Pacific, uma kubhekwa indawo enkulukazi, indawo yokuncintisana iyisifunda kakhulu. Nokho, uma umuntu ebheka umthelela nje: Abakhiqizi baseShayina nabamaNdiya ziba yisizinda samandla evolumu nokukhula. Okwamanje, kusungulwe izinkampani ezisebenzisana naseNtshonalanga (Ingal/Valmont, Trinity nge-reps yendawo) gcina ubukhona obuqinile ezimakethe lapho kudingeka khona izixazululo ezisezingeni eliphezulu noma eziyisipesheli.

Ekugcineni, isici esithakazelisayo ukukhiqizwa kukahulumeni: Kwamanye amazwe (njenge-China, ngokwezinga elithile), ama- guardrail angase akhiqizwe amabhizinisi kahulumeni kumaphrojekthi athile. Isibonelo, iminyango yomgwaqo onguthelawayeka e-Shayina inezinkundla zokucobelelana ngolwazi ezingafaka izinsimbi zokuqapha uma kudingeka, nakuba lokhu kuvamile manje ngenxa yokutholakala kwezinkampani ezizimele.

(Imakethe yase-Asia Pacific i enamandla kakhulu. Amafemu aseShayina namaNdiya kulindeleke ukuthi aqhubeke nokwandisa umkhiqizo kanye nekhwalithi, okungenzeka acindezele izimbangi ezinezindleko eziphezulu. Ngesikhathi esifanayo, izindinganiso zasendaweni nezintandokazi ziqinisekisa ukuthi abadlali basekhaya abafana no-Ingal (Aus) noma i-Nippon (Japan) bagcina inkundla yabo yasekhaya. Njengoba kuqhubeka ukunwetshwa kwengqalasizinda, i-APAC izohlala iyisifunda esibalulekile sokukhula kwesidingo se-Guardrail (Ucwaningo lweMakethe ye-Highway Guard Rails: Ucwaningo Olujulile lwango-2032).)

Isiphetho

Kuzo zonke izifunda, I-W-beam kanye ne-Thrie-beam guardrails zihlale zibalulekile ekuphepheni emgwaqeni, futhi imakethe yazo ikhombisa okubalulekile kwengqalasizinda yesifunda ngasinye kanye nezimo zomnotho. i-America esenyakatho ikhombisa isidingo esiqinile esisekelwa ukutshalwa kwezimali okusha futhi kubuswa amafemu ambalwa amisiwe; Europe igcizelela ukuthuthukiswa kokuphepha futhi ihlinzekwa yinhlanganisela yezinkampani ezidumile kanye nochwepheshe besifunda; i Emaphakathi Mpumalanga ibona ukukhula okuxhumene nemiklamo yentuthuko nabakhiqizi bezifunda nabangenisa kwamanye amazwe abagaqele ibhizinisi; i-South America yandisa kancane kancane ingqalasizinda yayo yokuphepha kothelawayeka, ithola kubahlinzeki basekhaya nabamazwe ngamazwe; futhi Asia Pacific ihola esikalini, i-China ne-India ishayela ukukhiqizwa nokusetshenziswa kwamazinga amasha.

Isifunda ngasinye sinendawo yaso ehlukile yamagama angukhiye, kodwa ngokwemibandela ehunyushwa emhlabeni wonke umgoqo wokuvikela/ukuphepha ziyakwazi ukukhonjwa, okubonisa ukuqonda okufanayo kwalawa madivayisi okuphepha emhlabeni jikelele. Isidingo semakethe sixhumene kakhulu nokuthuthukiswa kwengqalasizinda kanye nezinhlelo zokuphepha emgwaqeni, okusho ukuthi njengoba amazwe etshala imali emigwaqeni, kulandela isidingo se- guardrail. Ngokuncintisana, kuyilapho abanye abadlali bomhlaba (abanjengoTrinity/Valtir noma i-Valmont) betholakala cishe yonke indawo, imboni isabona abadlali besifunda abaqinile abenzelwe izindinganiso nemibandela yendawo.

Kafushane, imakethe ye-Guardrail yomhlaba wonke iqinile futhi iyakhula, inama-nuances esifunda kumagama okusesha nokuncintisana kodwa inhloso eyabiwe imigwaqo ephephile ngokusebenzisa izithiyo ezithembekile ze-W-beam kanye ne-Thrie-beam (Ucwaningo lweMakethe ye-Highway Guard Rails: Ucwaningo Olujulile lwango-2032) (Ukubuka Kwemboni Okujulile: INyakatho Melika, iYurophu, iNingizimu Melika, kanye ne-Middle East Guardrail Board Usayizi Wemakethe, Isibikezelo). Ukutshalwa kwezimali okuqhubekayo kwengqalasizinda yemigwaqo kanye nokuphepha kuzoqinisekisa ukuthi laba “banakekeli abathule” emigwaqweni yethu emikhulu bahlala befunwa kakhulu emhlabeni wonke eminyakeni ezayo.
