Zvimiro zveAASHTO M180 Steel Posts
High Strength AASHTO M180 posts, nekugadzirwa, yakagadzirwa kubva kune yakakwirira-yakasimba simbi, kunyanya Giredhi 345 kana 350. Icho chisarudzo chezvinyorwa zvinoreva kuti zvigaro zvinochengetedza kutendeseka kwemaitiro uye zvinokwanisa kupikisa mitoro yemigumisiro. Simbi yacho ichazadzisawo zvinodikanwa zveASTM zvesimbi seASTM A570 yesimbi inotonhora-yakaumbwa kana ASTM A588 yesimbi yekupisa.
Saizi Yakakura Zviyero zvinoisa hukuru hudiki hwemapango maererano nehurefu, dhayamita, uye ukobvu hwemadziro. Kufanana uku kunovimbisa kuiswa kwakakodzera uye kuenderana nedzimwe nhengo dze guardrail system.
Kudzivirirwa Pakuora Kumira nemamiriro ekunze akaoma uye zvimwe zvinhu zvekunze, AASHTO M180 inoda kuti mbiru dzesimbi dzive nemarara, kuvharwa, kana kurapwa kuti dzibvise ngura. Izvi zvinogona kuitwa kuburikidza nekupisa-dip galvanization yehushoma hwekututira ukobvu neASTM A123 kana mamwe mazinga anopa yakaenzana corrosion dziviriro.
Kuisa Dhata Izvo zvinongedzo zvinopa maitiro ekuisa zvigaro nenzira yekuti zvinotsigirwa zvakakwana uye zvakaringana. Izvi zvinogona kuiswa pachishandiswa kucheresa kwakabvumidzwa, kutyaira, kana kongiri yekumisikidza maitiro uye inokurudzirwa nzvimbo uye kurongeka iyo inofanirwa kupa anoshanda uye anoyevedza magungano.

AASHTO M180 yakakosha mukuona kuti nzvimbo dzese dzemumugwagwa mukuru dzakachengeteka uye dzakavimbika zvakanyanya. Inotsanangura simbi yakakwirira-yakasimba, zviyero zvakarurama, uye zviyero zvakakodzera zvekupikisa kurwisana nekuora; nekudaro, kuburikidza nechiyero ichi, magadzirirwo ekuchengetedza anogadzirwa, ayo anozoratidza kuve akasimba uye anoshanda kushandira nekudzivirira vashandisi vemugwagwa zvakavimbika.
- High-Simba Simbi: Inobvumira maposita kutora mitoro yekukanganisa pasina kukundikana uchichengetedza chimiro.
- Standardized Dimensions: Inovimbisa kuenderana uye kuiswa kwakakodzera.
- Kurwisana Kurwisana: Dziviriro yenzvimbo kubva kune hukasha hwekufurira kwezvakatipoteredza.
- Installation Standards: Kuve nechokwadi chekuti iyo yakasimba inomisa positi uye kushanda zvinoenderana nedhizaini.
- Kushanda Kushanda: Kubva mumigwagwa mikuru kuenda kumigwagwa yemumakomo, mbiru idzi ndiwo musimboti wenzira dzekuchengetedza.
Mukupedzisa, kutevera AASHTO M180 mukugadzira mugwagwa mukuru wevarindi masisitimu kwakakosha pakuchengetedza uye kurarama kwenguva refu. Sezvo mbiru dzesimbi dzichapa iyi nhanho yakatanhamara yekushanda kunodiwa, kuchengetedzwa kwemigwagwa kunovandudzwa, uye ndizvo zvakaita hupenyu hwemunhu wese. Rumwe ruzivo kana rutsigiro runogona kuwanikwa nekusangana nevashandi veindasitiri uye kuongorora iyo yakazara AASHTO M180 yakatarwa.
