Daim ntawv thov ntawm cov yeeb nkab steel corrugated culvert hauv kev tsim kho txoj kev loj

cov yeeb nkab corrugated steel, kuj hu uacov yeeb nkab culvert, yog ib qhocov yeeb nkab corrugatedrau cov kav dej uas muab tso rau hauv qab txoj kev loj thiab txoj kev tsheb ciav hlau.cov yeeb nkab hlau corrugatedtxais yuav tus qauv tsim, kev tsim khoom hauv nruab nrab, lub voj voog luv luv; kev teeb tsa ntawm kev tsim kho vaj tse thiab kev teeb tsa profile tuaj yeem siv sib cais, lub sijhawm tsim kho luv luv, tib lub sijhawm los txo lossis tsuas yog pov tseg cov ntaub ntawv tsim kho ib txwm muaj, kev tiv thaiv ib puag ncig yog qhov dav; thiab yuav tsum hloov kho rau qhov deformation ntawm lub hauv paus, qhov xwm txheej ntawm lub zog yog qhov tsim nyog, los txo qhov zoo ntawm kev sib sau ua ke tsis sib xws, los daws qhov teeb meem ntawm kev puas tsuaj rau cov qauv pob zeb ntawm cov choj thiab cov yeeb nkab culverts hauv thaj chaw txias.

Raws li kev soj ntsuam, lub neej ua haujlwm ntawm cov hlau bellows tuaj yeem ntau dua 100 xyoo vim yog kev kho galvanized thiab asphalt tiv thaiv kev xeb. Cov yeeb nkab corrugated sib dhos siv Q235-A kub dov hlau phaj, thiab txhua lub voj voog muaj ntau daim hlau phaj txuas ua ke, thiab tom qab ntawd txuas ntev thiab pwm. Cov ntsia hlau txuas siv M 208.8 qib siab zog bolts thiab HRC35 qib nkhaus washers, qhov chaw ntawm cov hlau phaj yog kub-dip galvanized, cov pob qij txha phaj raug kaw nrog cov khoom siv sealing tshwj xeeb, lub hauv paus ntawm cov yeeb nkab culvert yog 50-100cm gravel bedding, nrog qhov compactness ntawm N95%, thiab qhov paving yog ua los ntawm M7.5 slurry masonry daim pob zeb, thiab qhov nqes hav ntawm cov yeeb nkab culvert ntws dej yog 5%. Dav dav corrugated hlau culvert ntxiv rau hom yeeb nkab saum toj no, muaj elliptical, flange hom tiav installation, thiab lwm yam, kev xa khoom thiab xa tawm kuj tuaj yeem ua raws li qhov sib piv ntawm sab nqes hav beveled.
