Geomembrane ua cov khoom siv tiv thaiv kev seepage kuj muaj qee qhov teeb meem tseem ceeb. Ua ntej tshaj plaws, lub zog kho tshuab ntawm cov yas dav dav thiab asphalt sib xyaw geomembranes tsis siab, thiab nws yooj yim tawg. Yog tias nws puas tsuaj lossis qhov zoo ntawm cov khoom zaj duab xis tsis zoo thaum lub sijhawm tsim kho (Muaj qhov tsis zoo, qhov, thiab lwm yam) Yuav ua rau xau; Qhov thib ob, cov qauv tiv thaiv kev seepage ntawm geomembrane yuav raug ntab vim yog lub siab ntawm roj lossis kua hauv qab daim nyias nyias, lossis nws yuav ua rau av qeeg vim yog hom kev tso tsis tsim nyog ntawm qhov chaw membrane. Qhov thib peb, yog tias geomembrane uas yooj yim tawg ntawm qhov kub qis siv rau hauv thaj chaw txias, nws txoj haujlwm tiv thaiv kev seepage yuav ploj mus; Qhov thib plaub, cov geomembranes dav dav muaj kev tiv thaiv ultraviolet tsis zoo thiab yooj yim laus thaum raug tshav ntuj ncaj qha rau lub sijhawm ntev thaum thauj mus los, khaws cia, tsim kho thiab ua haujlwm. Tsis tas li ntawd, nws yooj yim raug tom los ntawm cov nas thiab raug punctured los ntawm reeds. Vim yog cov laj thawj saum toj no, txawm hais tias geomembrane yog cov khoom siv tiv thaiv kev seepage zoo tagnrho, qhov tseem ceeb kom ua tiav cov txiaj ntsig xav tau yog nyob rau hauv kev xaiv cov polymer ntau yam, tsim qauv tsim nyog thiab kev tsim kho kom zoo.
Yog li ntawd, thaum siv geomembrane anti-seepage, cov kev cai yooj yim hauv qab no yuav tsum tau muab tso rau pem hauv ntej rau qhov zoo thiab kev ua tau zoo ntawm geomembrane:
(1) Nws muaj lub zog tensile txaus, tuaj yeem tiv taus qhov kev ntxhov siab tensile thaum lub sijhawm tsim kho thiab tso, thiab yuav tsis raug puas tsuaj nyob rau hauv qhov kev ua ntawm lub zog dej thaum lub sijhawm pabcuam, tshwj xeeb tshaj yog thaum lub hauv paus raug deformed heev, nws yuav tsis ua rau shear thiab tensile tsis ua haujlwm vim muaj kev hloov pauv ntau dhau.
(2) Raws li cov qauv tsim daim ntawv thov, nws muaj lub neej ua haujlwm ntev txaus, uas yuav tsum tsawg kawg phim lub neej tsim ntawm lub tsev, uas yog, nws lub zog yuav tsis raug txo qis dua tus nqi tsim qauv tso cai vim laus hauv lub sijhawm no.
(3) Thaum siv rau hauv cov chaw ua kua dej uas muaj zog heev, nws yuav tsum muaj kev tiv thaiv txaus rau kev tawm tsam tshuaj lom neeg.
