Daim ntawv thov ntawm geomembrane hauv hydraulic engineering
Geomembrane, ua ib yam khoom siv tiv thaiv dej ntws zoo, ua lub luag haujlwm tseem ceeb hauv cov haujlwm txuag dej. Nws cov kev ua tau zoo tiv thaiv dej ntws zoo heev, cov yam ntxwv yooj yim thiab yooj yim tsim kho thiab tus nqi qis ua rau geomembrane dhau los ua ib feem tseem ceeb ntawm cov haujlwm txuag dej.
Ua ntej tshaj plaws, thaum tsim cov pas dej, geomembrane tuaj yeem ua lub luag haujlwm zoo heev los tiv thaiv kev seepage. Vim tias cov pas dej feem ntau yog tsim nyob rau hauv hav lossis thaj chaw qis, cov xwm txheej geological nyuaj dua, yog li yuav tsum tau ua cov kev ntsuas zoo kom tsis txhob muaj kev xau ntawm qab ntawm lub pas dej 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 kev ruaj khov ntawm tag nrho cov pas dej.
Qhov thib ob, nws tseem yog qhov tsim nyog los siv geomembrane los txhawb cov nyhuv tiv thaiv kev seepage thaum lub sijhawm tsim kho cov levees. Lub dike yog ib qho qauv tsim los ntawm tib neeg uas nws lub hom phiaj tseem ceeb yog los tiv thaiv thaj chaw qis los ntawm dej nyab. Txawm li cas los xij, hauv cov txheej txheem kev tsim kho, yuav muaj ntau yam tsis paub tseeb uas ua rau muaj loopholes, lub sijhawm no, nws yog qhov tsim nyog los siv geomembrane rau kev kho.
Qhov thib peb, hauv kev tswj hwm tus dej thiab cov kwj deg, geomembrane kuj muaj ntau yam kev siv. Cov dej thiab cov kwj deg yog cov khoom tseem ceeb heev ntawm cov haujlwm txuag dej, lawv tsis tsuas yog tswj cov dej ntws, tiv thaiv cov liaj teb thiab cov chaw hauv nroog, tab sis kuj txhim kho qhov chaw ib puag ncig ntawm tag nrho thaj av. Txawm li cas los xij, hauv cov txheej txheem tswj hwm yuav ntsib qee qhov teeb meem nyuaj, xws li loopholes, landslides thiab lwm yam. Lub sijhawm no kev siv geomembrane tuaj yeem yog qhov kev daws teeb meem zoo rau cov teeb meem no.
