Raws li hom tshiab ntawm cov khoom siv polymer, cov khoom sib xyaw geomembrane tau siv dav hauv hydraulic engineering thiab kev tiv thaiv ib puag ncig engineering. Cov kev sib txuas ntawm cov geomembrane thiab daim nyias nyias muaj xws li cov txheej txheem sib txawv xws li kev sib koom ua ke, kev sib txuas thiab vuam. Vim nws txoj haujlwm ceev ceev thiab qib siab ntawm kev siv tshuab, kev tsim kho vuam tuaj yeem txo tus naj npawb ntawm cov neeg ua haujlwm ntawm qhov chaw thiab txo lub sijhawm tsim kho, thiab maj mam dhau los ua txoj hauv kev tseem ceeb rau kev teeb tsa thiab kev tsim kho ntawm cov geomembranes. Vuam txoj kev muaj xws li hluav taws xob wedge, kub yaj extrusion thiab kub kub gas vuam.
Ntawm lawv, hluav taws xob wedge vuam yog siv dav tshaj plaws. Cov kws tshaj lij hauv tsev thiab cov kws tshawb fawb tau ua qhov kev tshawb fawb tob tob txog cov cuab yeej siv vuam kub kub thiab tau txais qee qhov kev piav qhia tsis tu ncua thiab ntsuas ntau. Raws li cov kev ntsuam xyuas hauv cheeb tsam, lub zog tensile ntawm cov khoom sib txuas geomembrane yog ntau tshaj 20% ntawm lub zog ntawm cov khoom siv hauv paus, thiab qhov tawg feem ntau tshwm sim ntawm qhov tsis-welded ib feem ntawm weld ntug. Txawm li cas los xij, kuj tseem muaj qee cov qauv uas nws lub zog tensile tsis ua hauj lwm nyob deb ntawm cov qauv tsim los yog qhov tawg ntawm qhov pib ncaj qha los ntawm txoj haujlwm vuam. Nws ncaj qha cuam tshuam rau kev ua tiav ntawm cov nyhuv anti-seepage ntawm cov khoom sib xyaw geomembrane. Tshwj xeeb tshaj yog nyob rau hauv lub vuam ntawm composite geomembrane, yog welding tshwm sim, cov tsos ntawm cov weld raws li tus tsim, tab sis lub tensile lub zog ntawm lub weld feem ntau ua tsis tau raws li qhov yuav tsum tau tsim, thiab tej zaum yuav tsis muaj teeb meem nyob rau hauv lub sij hawm luv luv. Txawm li cas los xij, xav txog qhov ua haujlwm ntev ntawm qhov project, nws yuav cuam tshuam ncaj qha rau kev ua tiav ntawm kev tiv thaiv lub neej ntawm qhov project. Yog tias muaj teeb meem, qhov tshwm sim yuav loj dua.
Txog rau qhov kawg no, peb tau taug qab thiab txheeb xyuas qhov kev siv vuam ntawm HDPE geomembrane, thiab cais cov teeb meem tshwm sim hauv cov txheej txheem tsim kho, txhawm rau ua qhov kev tshawb fawb sib txawv thiab nrhiav kev ntsuas kev txhim kho kom zoo. Feem ntau cov teeb meem zoo hauv kev tsim cov khoom sib txuas geomembrane vuam feem ntau suav nrog kev vuam ntau dhau, vuam ntau dhau, tsis muaj vuam, wrinkling, thiab ib nrab vuam ntawm cov hlaws vuam.
