Xaiv Ib Lub Geomembrane Zoo Li Cas？

Hauv kev tiv thaiv seepage engineering, geomembrane yog qhov khoom siv tiv thaiv-nplooj ntawv tseem ceeb, thiab nws yog qhov tseem ceeb heev kom xaiv geomembrane ntawm cov khoom sib txawv zoo rau qhov project anti-seepage. Dav dav yog qhov taw qhia tseem ceeb ntawm geomembrane, thiab qhov dav dua tuaj yeem nqa ntau cov txiaj ntsig rau cov phiaj xwm los tiv thaiv. Rau cov phiaj xwm nrog thaj chaw loj xws li cov pas dej tauv lossis cov suab thaj evaporated, cov khoom siv dav siv geomembrane yuav tsum siv.

Hauv qhov phiaj xwm anti-seepage, qhov txuas ntawm chaw mos yog qhov ntau dua los tsim cov ntsiab lus to. Qhov dav dua qhov dav dav geomembrane, qhov txuas tau tsawg dua cov khoom tsim tawm thaum lub sijhawm siv cov vuam kev siv tiag tiag, thiab cov hlau txuas muaj tsawg dua, kev muaj peev xwm xau tsawg dua, thiab muaj ntau qhov kev nyab xeeb rau kev tiv thaiv tawm tsam.

Ntxiv mus, qhov nce hauv qhov dav ntawm geomembrane thiab qhov poob qis hauv qhov txuas kuj tseem coj tau ob qho txiaj ntsig ntxiv rau qhov haujlwm los tiv thaiv kev pom. Ib qho yog los txo cov ceg tawv poob thaum vuam siv: Sib piv cov geomembrane nrog qhov dav ntawm 6 metres thiab geomembrane nrog qhov dav ntawm 5 meters, qhov theoretical poob tus nqi tuaj yeem txo los ntawm 14%, uas yog cov txiaj ntsig zoo rau kev txo nqi ntawm qhov project Cov. Lwm qhov taw qhia yog tias vim tias yuav txo tau ntawm qhov vuam nqaws, lub sijhawm thiab lub zog uas yuav tsum muaj rau vuam kuj tseem yuav raug txo, uas tuaj yeem txo lub sijhawm tsim kho ntawm qhov haujlwm los tiv thaiv phab ntsa thiab cov nqi zog coj ua. Cov qauv no tau pom tseeb hauv qee qhov kev ua haujlwm loj los tiv thaiv nplooj ntawv nrog kev tsim kho lub sijhawm siv nruj.
