Umda wokubeka i-geomembrane edibeneyo

Ukusebenza kobomi bokusebenza kwe-geomembrane ehlanganisiweyo kumiselwa ikakhulu ukuba ifilimu yeplastiki iphantsi konyango lokugxotha amanzi.Ngokwemigangatho kazwelonke yeSoviet Union, ifilimu ye-polyethylene enobunzima be-0.2m kunye ne-stabilizer yobunjineli be-hydraulic inokusebenza iminyaka engama-40 ukuya kwe-50 phantsi kweemeko zamanzi acocekileyo kunye neminyaka engama-30 ukuya kwe-40 phantsi kweemeko zamanzi amdaka.Idama leDama laseZhoutou ekuqaleni laliludonga olungundoqo, kodwa ngenxa yokudilika kwedama, inxalenye ephezulu yodonga olungundoqo yasuswa.Ukuze uphathe ukusebenza kwe-anti-seepage ephezulu, i-anti-seepage inclined wall yongezwa kwisiseko.Ngokuhambelana nomboniso wokhuseleko kunye nokubola kweDama laseZhoutou eligcina amanzi, ukuze kujongwane nokuvuza komphezulu obuthathaka kunye nokuvuza kwesiseko sedama okubangelwa kukudilika komhlaba okuphindaphindiweyo kwedama, izakhiwo zomzimba ezingenamandla ezifana nokugrumba kwebhedi, ukugrumba umphezulu wedabi, ukugungxulwa kunye nokugungxulwa. ukubamba umkhusane wokuzalisa umva kakuhle, kunye nodonga lweplate yejethi yoxinzelelo oluphezulu olungenakungeneka luye lwamkelwa ngokwemiqathango yothintelo lwamanzi oluthe nkqo.
Iimpawu ze-geomembrane edibeneyo: I-geomembrane edibeneyo yimathiriyeli ye-geomembrane eyenziwe ngefilimu yeplastiki njenge-anti-seepage substrate kunye ne-nonwoven fabric.Umsebenzi wayo wokuchasana nokubona uxhomekeke kumsebenzi ochasene ne-seepage wefilimu yeplastiki.Indlela yayo yoxinzelelo yeyokuba ukungagungqi kwefilim yeplastiki kugquma indlela yokuvuza kwedama lomhlaba ukusuka emanzini, ukumelana noxinzelelo lwamanzi kunye nokuziqhelanisa noguquko lwamadama ngenxa yokuqina kwawo okukhulu kunye nesantya sokulibaziseka;Ilaphu elingalukwanga likwayimathiriyeli yekhemikhali yeentsinga zepolymer ezimfutshane, eziyilwe ngokuhlatywa ngenaliti okanye ukudityaniswa kwe-thermal, kwaye inamandla aphezulu kunye nokulibaziseka.Emva kokuqhagamshelwana neefilimu zeplastiki, akwanelisi nje kuphela amandla okuqina kunye nokumelana nokugqabhuka kweefilim zeplastiki, kodwa ikwanyusa i-coefficient ye-friction yomphezulu wedabi ngenxa yeenkcukacha ezirhabaxa zamalaphu angalukwanga, aluncedo kuzinzo lwe-geomembranes ehlanganisiweyo. kunye nemigangatho yokufihla.
Ngoko ke, ubomi bokusebenza kwe-geomembrane ehlanganisiweyo banele ukwanelisa ubomi bokusebenza obuceliweyo kuthintelo lokuphuma kwedama.
Udonga oluphezulu oluthambekele lugqunywe nge-geomembrane ehlanganisiweyo yokuthintela ukungena kwamanzi, kunye nenxalenye esezantsi ilandela udonga oluthe nkqo lokuthintela ukungena kwamanzi kunye nendawo ephezulu ifikelele kumphakamo wama-358.0m (0.97m ngaphezu komgangatho wokukhangela izikhukhula).
Ukumelana nobushushu obuphezulu, ukusebenza kakuhle kwe-antifreeze.
Okwangoku, iifilimu zeplastiki ezisetyenziselwa ukulawulwa kwe-seepage ekhaya nakwamanye amazwe ziquka i-polyvinyl chloride (PVC) kunye ne-polyethylene (PE), eziyi-polymer chemicals flexible materials ezinobunzima obuphantsi, ukulibaziseka okunamandla, kunye nokuguquguquka okuphezulu kwi-deformation.
Kwangaxeshanye, banokumelana kakuhle neebhaktheriya kunye nokuvuselela iikhemikhali, kwaye abayoyiki iasidi, ialkali, kunye netyuwa.
