Cov geomembrane muaj zog
Kev Piav Qhia Luv:
Cov geomembrane uas muaj zog yog cov khoom siv geotechnical sib xyaw ua ke los ntawm kev ntxiv cov khoom siv txhawb nqa rau hauv geomembrane los ntawm cov txheej txheem tshwj xeeb raws li geomembrane. Nws lub hom phiaj yog txhim kho cov khoom siv kho tshuab ntawm geomembrane thiab ua kom nws hloov kho tau zoo dua rau ntau qhov chaw ua haujlwm engineering.

Cov yam ntxwv
Muaj Zog Siab:Qhov ntxiv ntawm cov ntaub ntawv txhawb nqa ua rau lub zog ntawm geomembrane zoo dua qub, ua rau nws muaj peev xwm tiv taus cov zog sab nraud xws li lub zog tensile, lub zog siab thiab lub zog shearing, txo qhov deformation, kev puas tsuaj thiab lwm yam xwm txheej thaum lub sijhawm tsim kho thiab siv.
Muaj peev xwm tiv thaiv kev hloov pauv zoo:Thaum raug rau cov zog sab nraud, cov khoom siv txhawb nqa hauv cov geomembrane txhawb nqa tuaj yeem tiv thaiv kev hloov pauv ntawm geomembrane, ua kom nws zoo thiab ruaj khov. Nws ua tau zoo heev tshwj xeeb tshaj yog hauv kev daws teeb meem tsis sib xws thiab kev hloov pauv ntawm lub hauv paus.
Kev Ua Tau Zoo Tshaj Plaws Los Tiv Thaiv Kev Nqus Dej:Txawm hais tias muaj lub zog siab thiab tiv thaiv kev hloov pauv, lub geomembrane uas muaj zog tseem khaws cia qhov kev ua tau zoo tiv thaiv kev seepage ntawm geomembrane, uas tuaj yeem tiv thaiv kev xau ntawm dej, roj, tshuaj lom neeg, thiab lwm yam, kom ntseeg tau tias muaj kev cuam tshuam tiv thaiv kev seepage ntawm qhov project.
Kev Tiv Thaiv Kev Sib Tsoo thiab Kev Tiv Thaiv Kev Laus:Cov ntaub ntawv polymer thiab cov ntaub ntawv txhawb nqa uas ua rau cov geomembrane txhawb nqa feem ntau muaj kev tiv thaiv corrosion zoo thiab tiv thaiv kev laus, ua rau lawv ua haujlwm ruaj khov rau lub sijhawm ntev nyob rau hauv ntau yam xwm txheej ib puag ncig thiab ua kom lub neej ua haujlwm ntawm qhov project ntev dua.
Cov Cheeb Tsam Siv
Cov Haujlwm Txuag Dej:Nws yog siv rau kev tiv thaiv kev ntws thiab kev txhawb nqa ntawm cov pas dej, pas dej loj, cov kwj dej, thiab lwm yam. Nws tuaj yeem tiv taus lub zog dej thiab lub zog ntawm cov av pas dej loj, tiv thaiv kev xau thiab teeb meem kav dej, thiab txhim kho kev nyab xeeb thiab kev ruaj khov ntawm cov haujlwm txuag dej.
Cov chaw pov tseg:Raws li cov ntaub thaiv kev nqus dej ntawm cov chaw pov tseg, nws tuaj yeem tiv thaiv cov leachate kom tsis txhob ua rau cov dej hauv av thiab av qias neeg, thiab tib lub sijhawm dais lub siab ntawm cov khib nyiab.
