1. Ngaba kukho nayiphi na impembelelo evela kukuhanjiswa kwefilimu?Emva kokuba ifilimu ibekwe, umgca wokungena ngaphambi kokuba ifilimu iphakame kancane, ngelixa umgca wokungena emva kokuba ifilimu iyancipha kakhulu.Ngexesha elifanayo, intloko yamanzi rhoqo ephantsi kwefilimu iba yincinci, kwaye intloko yamanzi emva kwefilimu iyancipha ngokukhawuleza.Ukuhanjiswa kweegradients zehydraulic kuye kwatshintsha kakhulu.Ngaphambi kokubeka ifilimu, kukho indawo encinci ye-hydraulic gradient kwindawo ekudibaneni komhlaba ovunduvundu kunye nodongwe, kodwa emva kokubeka ifilimu, i-hydraulic gradient kwi-dike iba yincinci, ngelixa i-hydraulic gradient isezantsi kwendawo. ifilimu iyanda kakhulu, ebonisa ukuba ukuhamba kwamanzi kutshintshile ngenxa yobukho befilimu Kwindlela yokuhamba, i-seepage igxininiswe ukusuka ngaphantsi kwe-membrane, oko kukuthi, i-membrane echasene ne-seepage inefuthe elibalulekileyo lokuchasana ne-seepage.Ngaphandle kwendawo encinci ephantsi kwexabiso lefektri ye-geomembrane textured, i-hydraulic gradients kwezinye iindawo zonke zingaphakathi kwendawo evumelekileyo ye-hydraulic gradient range, kunye nezantsi kwe-membrane kuluhlu olusezantsi lweprojekthi yonke, kunye noluhlu oluncinci. kwaye akukho monakalo we-osmotic uya kwenzeka.
2. Impembelelo yobuninzi befilimu.Xa umphantsi we-membrane u-0.5m kude nodaka lodongwe, xa kuthelekiswa nomgangatho wodongwe ofakwe emazantsi enwebu, umgca wokumanzisa emva kokwanda kwenwebu, intloko yamanzi iyanda kakhulu, kunye nentloko yamanzi ezantsi kwe-membrane. i-membrane iba yincinci, ibonisa i-anti-seepage effect ye-membrane ye-anti-seepage ethe nkqo iyancipha kakhulu.Ingabonwa ukuba xa umaleko anti-seepage yendalo ezifana umaleko yodongwe ekhoyo ekuhlaleni, nokuba umaleko yodongwe ifakwe emazantsi inwebu inempembelelo enkulu kwisiphumo anti-seepage inwebu.Xa uluhlu lodongwe lufakwe kwi-bottom of the membrane, umqobo ovaliweyo ongenakunqandwa wenziwa.Xa kuthelekiswa xa udongwe lungafakwanga ngaphantsi kwe-membrane, i-anti-seepage effect iphuculwe kakhulu.Xa umaleko wodongwe ungafakwanga ezantsi kwenwebu, kukho umaleko omncinci ongenekayo phakathi kwenwebu enganyangekiyo kunye nodongwe.Xa amanzi equkuqela ukuya kwindawo eyingqongileyo, kwenziwa umjelo oqinileyo wokukhupha amanzi.Xa i-bottom ye-membrane ikude nodongwe, ubukhulu bomgangatho ogqithisiweyo buyanda, umphumo wokungena uyanda, kunye nefuthe elichasayo le-anti-seepage membrane liyancipha.
Xa ezantsi inwebu enganyangekiyo ayifakwanga kulwele yodongwe, ukuthambeka hydraulic ukwanda kwindawo kufutshane ezantsi geomembrane wholesale textured, kodwa kuncipha umaleko yodongwe.Xa kuthelekiswa nemeko yokungabikho kwe-membrane, i-hydraulic gradient yodaka lodongwe ezantsi kwe-membrane iyanda, kwaye i-hydraulic gradient yodaka lodongwe emva kwe-membrane iyancipha, ebonisa ukuba ukuhamba kwamanzi kugxininiswe phambi kwe-membrane, kwaye ngenxa yokutshintsha kwendlela yokuhamba kwamanzi, amanzi amaninzi ahamba emva kwe-membrane.Ukunyuka okunyukayo kunciphisa ukuxinana komjelo kumda womaleko womhlaba, nto leyo esanceda ukuzinza kokumanzisa elunxwemeni.Ukongezelela, i-hydraulic gradient yoluhlu ngalunye (ngaphandle kwenxalenye encinci ezantsi kwe-membrane) isencinci kune-gradient ye-hydraulic gradient evumelekileyo, ngoko ke xa umzantsi we-membrane ungagqunywanga ngodaka lodongwe, ukungaphumeleli kokungena kuya ngokuqhelekileyo. ayinakwenzeka, kodwa isiphumo esichasene nephepha le-membrane ethe nkqo iya kuba kukuncipha okucacileyo.
3. Umphumo wokuqhekeka kwe-membrane.Xa i-membrane itshatyalalisiwe, iziteshi ze-seepage ezintsha ziyakwenziwa, ezibangela ukuhanjiswa kwakhona kwendawo yokubona.Umgca wokungena emva kwe-membrane wanda kakhulu, kwaye intloko yamanzi yanda kakhulu, ngakumbi kwindawo eyonakalisiweyo.Impembelelo echasene ne-seepage ye-membrane ye-anti-seepage iyancipha ngokucacileyo.I-hydraulic gradient ngaphambi nangemva kokuba i-membrane eveliswa ngabavelisi be-LDPE geomembrane iphukile ngokucacileyo iyanda, ngelixa i-hydraulic gradient kwezinye iindawo iyancipha, ebonisa ukuba ukuhamba kwamanzi kwi-membrane kwaphukile, kodwa ukwanda kwe-gradient ebangelwa yi-osmotic concentration. impembelelo encinci.Xa i-dike ibonelela ngejelo elide le-seepage, aliyi kuchaphazela uzinzo lwe-dike.Ukongezelela, i-hydraulic gradient yezinye iileyile iyancitshiswa, encinci kune-hydraulic gradient evumelekileyo, ngoko xa i-membrane ichithwa, ukuhluleka kwe-osmotic akuyi kwenzeka.
