Ingxenye yokulala kufanele ilinganiswe futhi ungqimba olushintshayo olunogqinsi olungaba ngu-30 cm kanye nobukhulu bezinhlayiyana ububanzi obungama-20 mm we-geomembrane eyinhlanganisela kufanele kubekwe.Ngokufanayo, ungqimba lokuhlunga kufanele lubekwe kulwelwesi, lulandelwe ungqimba oluvikelayo.I-periphery ye-membrane kufanele ihlanganiswe ngokuqinile nongqimba olungangeneki lwemithambeka yasebhange kuwo womabili amabhange.Ukuxhumana phakathi kwe-membrane engangenisi kanye nomsele okusetshenzwa kulengwa kuwo kunqunywa ngokusekelwe kwigradient evumelekile yokuxhumana phakathi kolwelwesi kanye nokhonkolo.I-Polyvinyl chloride namafilimu enjoloba ye-butyl angabambelela kahle endaweni ekhonkolo esebenzisa izinto zokunamathisela noma izincibilikisi, ngakho ubude obushunyekiwe bungaba bufushane ngokufanelekile.Ngenxa yokungakwazi kwefilimu ye-polyethylene ukunamathela endaweni ekhonkolo, ubude bokhonkolo oshunyekiwe buzoba okungenani ngu-0.8m.
I-Geomembrane iyimpahla ye-geosynthetic enokungena kwamanzi okuphansi kakhulu.Ukuze i-membrane idlale indima yayo efanele ekuvimbeleni ukugeleza kwamanzi, ngaphezu kokudinga ukuthi i-membrane ngokwayo ingabonakali, ukunakwa kufanele futhi kukhokhwe kukhwalithi yokwakha yokubeka ulwelwesi olungenakunyakaziswa.
1. Ukuxhumana phakathi kwe-membrane engangenisi kanye nomngcele ozungezile.I-membrane engangenisi kufanele ihlanganiswe ngokuqinile nomngcele ozungezile.Ngesikhathi sokwakhiwa, i-anchor groove ingambiwa ukuze kuxhunywe isisekelo kanye ne-bank slope.
Uma isisekelo siwungqimba olungenamanzi lwesihlabathi olungenamanzi, uhla lwesanti kufanele lumbiwe luze lucebe edwaleni, bese kuthelwa isisekelo sikakhonkolo ukuze kulungiswe i-geomembrane kukhonkolo.Uma isisekelo siwungqimba lobumba olungenakunyakaziswa, kungambiwa umsele wehange onokujula okungama-2m nobubanzi obungama-4m.I-geomembrane ifakwa emseleni, bese ubumba lugcwaliswa ngemuva.Uma isisekelo siwungqimba olujulile lwesanti namatshe oluvunyelekayo, i-geomembrane ingasetshenziswa ukusimboza ukuze kuvinjelwe ukugeleza kwamanzi, futhi ubude baso bunqunywa ngokusekelwe ekubaleni.
Indawo ethintana nayo phakathi kwe-membrane engangenisi kanye nezinto ezisekelayo kufanele ibe bushelelezi ngangokunokwenzeka ukuze kuvinjwe ulwelwesi ukuthi lungalahlekelwa umphumela walo ongangeneki ngokubhobozwa emthambekeni.Uma kungenjalo, kufanele kuhlinzekwe ungqimba olushisayo olunezinhlamvu ezinhle ukuze kuvikelwe ifilimu emonakalweni.
3. Ukuxhumana kwe-membrane engangenisi ngokwayo.Izindlela zokuxhuma zefilimu emanzi engagxili zingafingqwa zibe izinhlobo ezintathu, okungukuthi, indlela yokubopha, indlela yokushisela, kanye nendlela ye-vulcanization.Ukukhethwa kuncike ezintweni zokusetshenziswa ezihlukene zefilimu engagxili, futhi ukungagxili kwawo wonke amalunga okuxhumana kufanele kuhlolwe.I-geomembrane eyinhlanganisela kufanele isetshenziselwe ukuvimbela ukuvuza ngenxa yokungaxhumi kahle kwamalunga.
