Ithangi lokugcina lisetshenziselwa ukugcina isitsha esivaliwe sensimbi ewuketshezi noma igesi, ubunjiniyela bethangi lokugcina buyi-petroleum, amakhemikhali, okusanhlamvu namafutha, ukudla, ukuvikelwa komlilo, ezokuthutha, i-metallurgy, ukuvikela izwe kanye nezinye izimboni ingqalasizinda ebalulekile ebalulekile, izidingo zalo eziyisisekelo nazo ziqinile impela. Ingqimba yomhlabathi eyisisekelo kufanele ihlangabezane nezidingo zenani lomklamo womthamo wokuthwala, futhi kufanele iphathwe ngokuvuza nokungangeni komswakama, ngaphandle kwalokho ukuvuza kuzobangela ukungcola okukhulu emvelweni, futhi umhwamuko wamanzi ongaphansi komhlaba uzovela, futhi ithangi lensimbi lizogqwala. Ngakho-ke, ithangi likawoyela le-HDPE i-geomembrane engangeni manzi iyinto engangeni manzi futhi engangeni manzi ekwakhiweni okuyisisekelo kwethangi lokugcina.
Ubuchwepheshe bokwakha i-geomembrane engangenwa ngamanzi endaweni yethangi likawoyela:
1. Ngaphambi kokuba kubekwe i-geomembrane engangenwa yithangi likawoyela, kuzotholakala isitifiketi sokwamukelwa esihambisanayo sobunjiniyela bezokwakha.
2. Ngaphambi kokusika, ubukhulu obufanele kufanele bulinganiswe ngokunembile, i-geomembrane ye-HDPE kufanele inqunywe ngokusika kwangempela, ngokuvamile hhayi ngokusayizi obonisiwe, kufanele ifakwe inombolo ngayinye, futhi iqoshwe ngokuningiliziwe efomini ekhethekile.
3. Kufanele silwele ukushisela kancane, ngaphansi kwesisekelo sokuqinisekisa ikhwalithi, ngangokunokwenzeka ukuze songe izinto zokusetshenziswa. Kulula futhi ukuqinisekisa ikhwalithi.
4. Ububanzi bokugoqana komthungo phakathi kwefilimu nefilimu ngokuvamile abungaphansi kuka-10cm, ngokuvamile ukuze ukulungiswa kwe-weld kuhambisane nomthambeka, okungukuthi, emthambekeni.
5. Ngokuvamile emakhoneni nasezigabeni ezikhubazekile, ubude bomthungo kufanele bube bufushane ngangokunokwenzeka. Ngaphandle kwezidingo ezikhethekile, emathafeni anemithambeka engaphezu kuka-1:6, ngaphakathi kwamamitha angu-1.5 ukusuka endaweni ephezulu noma endaweni yokugxila ekucindezelekeni, zama ukungafaki ama-weld.
6. Lapho kufakwa ifilimu engangenisi amanzi ethangini likawoyela, kufanele kugwenywe ukugoqa okwenziwe. Uma izinga lokushisa liphansi, kufanele liqiniswe futhi libekwe ngetshe ngangokunokwenzeka.
7. Ngemva kokuqedwa kokubekwa kwe-geomembrane engangenwa ngamanzi, ukuhamba phezu kobuso be-membrane, amathuluzi okunyakaza, njll. kufanele kuncishiswe. Izinto ezingalimaza i-membrane engangenwa ngamanzi akufanele zibekwe ku-membrane noma zithwalwe ku-membrane ukuze kugwenywe umonakalo ngengozi ku-membrane.
