Cov kav dej txuag dej yog ib qho chaw tseem ceeb rau kev faib cov peev txheej dej thiab kev ywg dej ua liaj ua teb, thiab nws txoj kev kho mob tiv thaiv kev ntws dej muaj feem cuam tshuam ncaj qha rau kev ruaj khov thiab lub neej ua haujlwm ntawm cov kav dej. Nyob rau hauv xyoo tas los no, ua ib hom khoom siv tiv thaiv kev ntws dej tshiab, cov khoom siv geomembrane tau siv dav hauv kev kho mob tiv thaiv kev ntws dej ntawm cov kav dej txuag dej. Yog li, puas zoo siv cov khoom siv geomembrane rau kev kho mob tiv thaiv kev ntws dej ntawm cov kav dej txuag dej? Daim ntawv no yuav tshuaj xyuas qhov zoo thiab qhov tsis zoo ntawm cov khoom siv geomembrane thiab nws daim ntawv thov hauv kev kho mob tiv thaiv kev ntws dej ntawm cov kav dej txuag dej.
Ua ntej, cia peb saib cov txiaj ntsig ntawm cov khoom sib xyaw geomembranes. Cov khoom sib xyaw geomembrane yog tsim los ntawm cov polymer molecular siab thiab geotextile, uas muaj kev ua tau zoo tiv thaiv kev seepage. Nws cov coefficient tiv thaiv kev seepage qis, uas tuaj yeem tiv thaiv dej nkag mus thiab txo qhov poob ntawm cov channel. Tsis tas li ntawd, cov khoom sib xyaw geomembrane kuj muaj lub zog tensile zoo thiab elongation thaum tawg, uas tuaj yeem hloov kho rau qhov deformation ntawm hauv qab ntawm cov channel thiab tswj cov qauv ruaj khov. Tib lub sijhawm, cov khoom sib xyaw geomembrane kuj muaj cov yam ntxwv ntawm kev tiv thaiv corrosion, kev laus tiv thaiv thiab kev tiv thaiv ultraviolet, thiab tuaj yeem siv tau ntev nyob rau hauv cov xwm txheej ib puag ncig hnyav.
Txawm li cas los xij, muaj qee qhov tsis zoo rau cov geomembranes sib xyaw. Ua ntej tshaj plaws, kev tsim kho yog qhov nyuaj thiab xav tau pab pawg neeg tsim kho thiab cov thev naus laus zis tsim kho. Kev tso cov geomembrane sib xyaw yuav tsum xyuas kom meej tias qhov tiaj tus thiab compactness ntawm daim nyias nyias nto, txwv tsis pub nws cov nyhuv tiv thaiv kev seepage yuav raug cuam tshuam. Tsis tas li ntawd, cov geomembrane sib xyaw kuj yuav tsum ceev faj kom tsis txhob raug puncturing thiab khawb los ntawm cov khoom ntse thaum lub sijhawm thauj mus los thiab khaws cia, kom tsis txhob rhuav tshem nws qhov kev ncaj ncees.
Hauv kev kho cov kav dej uas tsis pub dej ntws tawm, kev siv cov composite geomembrane muaj qee qhov zoo. Ua ntej tshaj plaws, cov composite geomembrane tuaj yeem tiv thaiv kev xau ntawm qab ntawm cov kav dej thiab txhim kho lub peev xwm khaws dej thiab kev siv dej ntawm cov kav dej. Qhov thib ob, lub sijhawm tsim kho ntawm cov composite geomembrane luv luv, uas tuaj yeem ua rau lub sijhawm tsim kho luv dua thiab txo tus nqi ntawm qhov project. Tsis tas li ntawd, cov composite geomembrane muaj lub neej ua haujlwm ntev, uas tuaj yeem txo cov kev kho thiab hloov cov kav dej thiab txo cov nqi txij nkawm.
Txawm li cas los xij, hauv kev kho cov dej ntws tawm ntawm cov kav dej txuag dej, peb kuj yuav tsum tau them sai sai rau qee qhov kev txwv ntawm cov geomembranes sib xyaw. Piv txwv li, thaum tso cov geomembrane sib xyaw, nws yog qhov tsim nyog los xyuas kom meej tias hauv qab ntawm cov channel yog tiaj tus thiab tsis muaj cov khoom ntse tawm kom tsis txhob puncturing lub membrane nto. Tsis tas li ntawd, cov geomembrane sib xyaw yuav tsum tau welded thiab kho tom qab tso kom ntseeg tau tias nws muaj kev ncaj ncees thiab ruaj khov. Cov kev cai tsim kho no txhua yam yuav tsum tau npaj thiab npaj ua ntej kev tsim kho.
Tsis tas li ntawd xwb, peb kuj yuav tsum tau them sai sai rau qhov kev hloov pauv ntawm cov khoom siv sib xyaw ua ke thaum siv mus sij hawm ntev. Txawm hais tias cov khoom siv sib xyaw ua ke muaj cov yam ntxwv ntawm kev tiv thaiv kev laus thiab kev tiv thaiv ultraviolet, nws cov kev ua tau zoo yuav raug cuam tshuam rau qee qhov thaum raug rau cov chaw ib puag ncig xws li tshav ntuj, nag thiab av ntev. Yog li ntawd, hauv kev kho cov dej tsis huv ntawm cov kav dej txuag dej, peb yuav tsum tau tshuaj xyuas thiab tswj cov khoom siv sib xyaw ua ke kom ntseeg tau tias nws ruaj khov thiab ua haujlwm tau ntev.
Hauv kev xaus lus, nws muaj qee qhov zoo thiab kev siv tau los siv cov khoom sib xyaw geomembrane rau kev kho cov kav dej tiv thaiv kev ntws. Cov khoom sib xyaw geomembrane ua lub luag haujlwm tseem ceeb hauv kev kho cov kav dej tiv thaiv kev ntws vim nws qhov kev ua tau zoo tiv thaiv kev ntws, kev hloov pauv zoo thiab lub neej ntev. Txawm li cas los xij, peb kuj yuav tsum paub txog qee qhov kev txwv thiab kev ceev faj hauv kev tsim kho thiab siv cov khoom sib xyaw geomembranes. Yog li ntawd, hauv kev siv ua haujlwm, peb yuav tsum xaiv thiab siv raws li cov xwm txheej tshwj xeeb, thiab txhawb kev tsim kho thiab kev tswj hwm kom ntseeg tau tias muaj txiaj ntsig zoo thiab kev nyab xeeb ntawm cov khoom sib xyaw geomembranes hauv kev kho cov kav dej tiv thaiv kev ntws.
