Kev siv geomembrane hauv hydraulic engineering
Geomembrane, raws li cov khoom siv los tiv thaiv dej, ua lub luag haujlwm tseem ceeb hauv kev txuag dej. Nws zoo heev los tiv thaiv kev ua haujlwm, lub teeb thiab kev tsim kho yooj yim thiab tus nqi qis ua rau geomembrane dhau los ua ib feem tseem ceeb ntawm kev txuag dej.
Ua ntej ntawm tag nrho cov, nyob rau hauv kev tsim kho ntawm reservoirs, geomembrane muaj peev xwm ua si ib tug zoo heev anti-seepage luag hauj lwm. Vim hais tias cov reservoirs feem ntau yog ua nyob rau hauv kwj ha los yog low-lying thaj chaw, cov geological tej yam kev mob yog complex, yog li ntawd yuav tsum tau siv cov kev ntsuas zoo kom tsis txhob muaj cov dej ntws ntawm lub hauv qab ntawm lub reservoir thiab cov pob zeb nyob ib puag ncig. Kev siv geomembrane tuaj yeem daws qhov teeb meem no tau zoo, thiab tseem tuaj yeem txhim kho kev nyab xeeb thiab ruaj khov ntawm tag nrho cov reservoir.
Qhov thib ob, nws tseem yuav tsum tau siv geomembrane los ntxiv dag zog rau kev tiv thaiv kev tawm tsam thaum lub sij hawm tsim kho cov levees. Lub dike yog ib tus neeg tsim qauv uas nws lub hom phiaj tseem ceeb yog los tiv thaiv cheeb tsam hauv qab los ntawm dej nyab. Txawm li cas los xij, hauv cov txheej txheem tsim kho, yuav muaj ntau yam tsis tuaj yeem ua rau muaj qhov tsis zoo, lub sijhawm no, nws yuav tsum tau siv geomembrane rau kev ntsuas kho.
Thib peb, hauv kev tswj hwm tus dej thiab channel, geomembrane kuj muaj ntau yam kev siv. Cov dej ntws thiab cov dej ntws yog cov khoom tseem ceeb ntawm cov dej txuag dej, lawv tuaj yeem tsis tsuas yog tswj cov dej ntws, tiv thaiv thaj av thiab hauv nroog infrastructure, tab sis kuj txhim kho ecological ib puag ncig ntawm tag nrho cheeb tsam. Txawm li cas los xij, hauv cov txheej txheem kev tswj hwm yuav ntsib qee qhov teeb meem nyuaj, xws li kev tsis sib haum xeeb, kev sib tsoo av thiab lwm yam. Lub sijhawm no, kev siv geomembrane tuaj yeem yog ib txoj hauv kev zoo rau cov teeb meem no.
