Cov yoj-beam guardrails tau dhau los ua thoob ntiaj teb hauv peb lub neej, txhim kho kev zoo nkauj ntawm peb lub ntiaj teb thaum tseem ua kom peb muaj kev nyab xeeb thaum mus ncig. Cov lus qhia no suav nrog cov lus piav qhia ntxaws txog yuav ua li cas cov khoom siv kev nyab xeeb tseem ceeb no raug teeb tsa.
Cov txheej txheem installation ntawm kev sib tsoo-resistant guardrails suav nrog:
Layout: Txhawm rau kom ntseeg tau tias qhov kev teeb tsa tau ua tiav raug, xav txog cov yam ntxwv uas twb muaj lawm, tshwj xeeb hauv cov khoom siv hauv av, kom tsis txhob muaj kev puas tsuaj thaum tsim kho.
Ncej Installation:
- Raws li cov qauv kos duab thiab layout, nruab cov ncej.
- Excavation tuaj yeem ua tiav rau kev tso lub hauv paus ntawm tus ncej. Tom qab excavation, lub cheeb tsam yuav tsum tau rov qab tsim nyog siv cov khoom tsim nyog thiab compacted nyob rau hauv cov khaubncaws sab nraud povtseg tsis ntau tshaj 10 cm txhua. Qhov compaction ceev yuav tsum tsis txhob tsawg tshaj li cov av uas nyob ib sab.
- Tom qab kev teeb tsa, cov ntawv tshaj tawm raug soj ntsuam thiab ua raws nrog lub theodolite kom ncav cuag txoj kab ncaj thiab du. Nyob rau hauv rooj plaub uas xav tau kev kho loj, tus ncej yuav raug tshem tawm lub hauv paus compacted, thiab tus ncej tshiab yuav rov nruab.
Wave Beam Installation:
- Kev teeb tsa ntawm yoj beam yog qhov tseem ceeb heev thiab tej zaum qhov nyuaj tshaj plaws.
- Cov ntu ib leeg yog butted ua ke nrog splicing bolts thiab txuas rau cov ncej nrog txuas bolts. Bolts yuav tsum tsis txhob nruj kom txog thaum tag nrho cov seem nyob rau hauv qhov chaw thiab npaj rau square. Ua li ntawd, kev kho me me tuaj yeem ua tau yog tias tsim nyog rau txoj kab ncaj nraim, tsis muaj pob lossis hollows.
- Wave beams yuav tsum tau teeb tsa nrog thawj ntu ntawm qhov thib ob, qhov thib ob tshaj qhov thib peb, thiab lwm yam nrog rau kev khiav tsheb khiav.
- Qhov saum npoo ntawm yoj kab teeb yuav tsum yog sib npaug nrog txoj kev curvature, thiab sab yuav tsum yog tib yam nrog txoj kev curvature.
- Tom qab tag nrho cov yoj kab teeb raug teeb tsa, tag nrho cov kab yuav tsum tau kho kom zoo. Tsuas yog thaum ob qho tib si nkhaus ua tau raws li qhov yuav tsum tau ua kom cov bolts thaum kawg nruj.
Cov Ntsiab Lus Tseem Ceeb:
- Wave beam guardrails yog cov txheej txheem semi-rigid interlocked corrugated steel panels txhawb nqa los ntawm cov ncej.
- Thaum lub sij hawm tsim kho, cov ncauj lus kom ntxaws txog cov chaw uas twb muaj lawm, tshwj xeeb tshaj yog cov khoom siv hauv av, yog xav tau.
- Tom qab kev teeb tsa, yuav tsum muaj kev sib raug zoo nrog txoj kev centerline.
- Kev txhim kho ntawm yoj kab teeb yuav tsum tau ua raws li txoj kab du thiab txuas ntxiv yam tsis muaj qhov tsis sib xws.
Nrog kev txhim kho kom zoo los ntawm cov kauj ruam ntxaws, yuav muaj kev ruaj ntseg thiab kev ua haujlwm ntawm kev sib tsoo-resistant yoj yoj beam guardrails, ua kom muaj kev nyab xeeb thiab kev tsim nyog.
