Dej nres phaj yog cov khoom siv hauv tsev ntau heev, thiab cov khoom siv yuav siv tau rau ntau qhov chaw, yog li txhua tus neeg hauv lub luag haujlwm ntawm cov khoom siv no kuj tsis tuaj yeem tsis quav ntsej, cov chaw tsim khoom lag luam dej nres yog ib qho yooj yim rau txhua tus los qhia qee qhov dej nres phaj. thiab kev siv, kuj tuaj yeem txhim kho kev paub thiab kev nkag siab ntawm tib neeg rau cov khoom siv zoo li no.
Kev ua haujlwm ntawm cov dej nres steel phaj: feem ntau yog siv rau cov qauv ua vaj tse, DAMS thiab lwm cov dej num loj, kev siv dej nres steel phaj nws tuaj yeem hloov txoj kev nkag mus ntawm dej, ncua txoj kev nkag mus ntawm dej, hauv kev tsim kho ib puag ncig ntawm cov dej ntws. tej zaum yuav muaj cov khoom tiv thaiv corrosion, hlau phaj dej nres tuaj yeem ua lub luag haujlwm hauv kev tiv thaiv corrosion.
Scope ntawm kev lag luam wholesale daim ntawv thov ntawm dej nres steel phaj:
Qhov, subway, pas dej ua ke, culvert, dej conservancy thiab hydropower engineering kev sib koom ua ke, high-sawv tsev hauv qab daus, underground chaw nres tsheb thiab lwm yam loj engineering kev sib koom ua ke.
Dej nres steel phaj, tseem hu ua hlau phaj dej nres txoj siv, yog cov khoom siv dej tsis zoo hauv engineering, suav nrog steel phaj, tooj liab phaj, alloy steel phaj, thiab lwm yam. kev siv steel phaj hlau phaj dej nres, tuaj yeem hloov txoj kev infiltration ntawm dej, ncua txoj kev infiltration ntawm dej.Hauv kev tsim kho qhov chaw uas cov dej xau tuaj yeem muaj cov khoom siv corrosion, cov hlau phaj dej nres siv tau tuaj yeem ua lub luag haujlwm hauv kev tiv thaiv corrosion.
Nyob rau hauv kev tiv thaiv engineering, hlau phaj waterstop tuaj yeem ua kom muaj kev tiv thaiv ntawm qhov project, cov hlau phaj waterstop kuj feem ntau siv rau cov kev xav tau siab impermeability, thiab qhov me me ntawm qhov project, xws li lub qhov dej ntawm lub smelter, hluav taws xob rauv. foundation pit, thiab lwm yam. Nyob rau hauv tus txheej txheem ntawm kev tsim kho, yuav muaj ib tug seam, thiab lub seam no yuav muaj peev xwm ntawm cov dej seepage.Yog li ntawd, nyob rau hauv cov ntaub ntawv no, ib txwm koj yuav tsum tau siv hom dej nres steel phaj, hom dej nres steel phaj yog siv nyob rau hauv kev tsim kho kev lag luam, tab sis kuj ntau dav.Ntawm chav kawm, lub luag hauj lwm ntawm cov dej nres steel phaj kuj loj heev.Nyob rau hauv tus txheej txheem ntawm kev tsim kho, tseem muaj ntau yam uas yuav tsum tau them sai sai rau.Tsuas yog nyob rau hauv txoj kev no tuaj yeem tso dej nres steel phaj ua tiav cov txiaj ntsig zoo.
Nyob rau hauv txhua yam kev tiv thaiv tej yaam num, cov lag luam wholesale cov neeg siv cov dej nres steel phaj yog ntau heev.Lawv tuaj yeem tsis tsuas yog txuag cov nqi, tab sis kuj ua tiav cov txiaj ntsig zoo.
