Kev siv cov yeeb nkab steel corrugated culverts hauv txoj kev loj engineering nthuav tawm qhov zoo.

Cov kav dej corrugated, qhov tseem ceeb rau underpasses ntawm txoj kev loj thiab kev tsheb ciav hlau, muaj cov qauv tsim qauv uas txhawb nqa kev ua haujlwm tau zoo, kev tsim khoom nruab nrab nrog lub sijhawm tsim khoom sai. Cov txheej txheem kev teeb tsa tuaj yeem tshwm sim ntawm nws tus kheej, txo qis kev tsim kho lub sijhawm thaum txo kev cia siab rau cov khoom siv hauv tsev, yog li txhim kho ib puag ncig kev ruaj ntseg. Tsis tas li ntawd, cov kav dej no tuaj yeem ua kom haum lub hauv paus deformation thiab faib kev quab yuam kom zoo, txo cov kev pheej hmoo cuam tshuam nrog kev sib haum xeeb tsis sib xws thiab tiv thaiv cov pob zeb ua vaj tse tiv thaiv kev puas tsuaj - tshwj xeeb tshaj yog nyob rau hauv huab cua txias.

Kev sib dhos steel bellows tuaj nyob rau hauv ntau yam duab: arch, ncig, thiab horseshoe. Txhua qhov sib txawv ua haujlwm tshwj xeeb engineering xav tau.

Kev tshawb fawb qhia tau hais tias kev kho kom zoo steel bellows tuaj yeem ua tiav lub neej kev pab ntau tshaj 100 xyoo, ua tsaug rau galvanization thiab tshwj xeeb asphalt corrosion tiv thaiv. Cov qauv siv Q235-A kub-kuav los tiag steel phaj, txuas ntau lub vaj huam sib luag steel rau hauv ib qho kev sib koom ua ke, ua raws li kev sib txuas ntev thiab molding. High-strength bolts (M 208.8 qib) thiab nkhaus washers (HRC35 qib) ruaj ntseg kev sib txuas, thaum kub-dip galvanized nto tiv thaiv corrosion. Txhua culvert lub hauv paus nta ib pob zeb txaj ntawm 50-100 cm ntawm 95% compaction, nrog M7.5 slurry masonry siv rau lub qhov filling. Cov dej ntws incline nyob rau hauv lub culvert feem ntau ntsuas 5%. Ib cag ntawm cov duab zoo tshaj plaws, cov culverts kuj muaj xws li elliptical thiab flanged hom, nrog rau sab slopes customizable rau inlet thiab qhov hluav taws xob tsim.
