Ithangi lesitoreji lisetshenziselwa ukugcina uketshezi noma igesi yensimbi evalwe isitsha, ubunjiniyela bethangi lokugcina i-petroleum, amakhemikhali, okusanhlamvu namafutha, ukudla, ukuvikelwa komlilo, ezokuthutha, i-metallurgy, ukuvikela kazwelonke kanye nezinye izimboni ingqalasizinda ebalulekile, izidingo zayo eziyisisekelo nazo ziqinile impela. . Isendlalelo senhlabathi yesisekelo kufanele sihlangabezane nezidingo zenani lokuklama lomthamo wokuthwala, futhi kufanele siphathwe nge-seepage kanye nobufakazi bomswakama, ngaphandle kwalokho ukuvuza kuzodala ukungcoliswa okukhulu kwemvelo, futhi umhwamuko wamanzi ongaphansi komhlaba uzovela, futhi ithangi lensimbi lizogqwala. Ngakho-ke, ithangi likawoyela we-HDPE i-geomembrane engaboli iyinto engangenwa amanzi futhi efaka umswakama ekwakhiweni okuyisisekelo kwethangi lokugcina.
Indawo yethangi likawoyela ebeka ubuchwepheshe bokwakhiwa kwe-geomembrane obungangeneki:
1. Ngaphambi kokuthi ithangi likawoyela libekwe i-geomembrane engangeneki, kuzotholwa isitifiketi sokwamukela esihambisanayo sobunjiniyela bomphakathi.
2. Ngaphambi kokusika, izilinganiso ezifanele kufanele zilinganiswe ngokunembile, i-HDPE geomembrane kufanele isikwe ngokuvumelana nokusikwa kwangempela, ngokuvamile hhayi ngokuhambisana nobukhulu obubonisiwe, kufanele ibalwe ngayinye ngayinye, futhi ibhalwe ngokuningiliziwe efomini elikhethekile.
3. Kufanele alwele ukushisela kancane, ngaphansi kwesisekelo sokuqinisekisa izinga, ngangokunokwenzeka ukuze wonge izinto zokusetshenziswa. Kulula futhi ukuqinisekisa izinga.
4. Ububanzi bokugqagqana komthungo phakathi kwefilimu nefilimu ngokuvamile abukho ngaphansi kuka-10cm, ngokuvamile ukuze ukuqondanisa kwe-weld kuhambisane nomthambeka, okungukuthi, eduze nomthambeka.
5. Ngokuvamile emakhoneni nasezigabeni ezikhubazekile, ubude be-seam kufanele bube bufushane ngangokunokwenzeka. Ngaphandle kwezidingo ezikhethekile, emithambekeni enemithambeka emikhulu kuno-1:6, phakathi kwamamitha angu-1.5 ukusuka endaweni emthambekeni ephezulu noma endaweni yokugxilisa ingqondo, zama ukungawafaki amashisela.
6. Ekubekeni ithangi lamafutha ifilimu engenakunyakaziswa, ukugoqa okwenziwayo kufanele kugwenywe. Uma izinga lokushisa liphansi, kufanele liqiniswe futhi ligandaywe ngangokunokwenzeka.
7. Ngemuva kokuqedwa kokubeka i-geomembrane engenakunyakaziswa, ukuhamba phezu kwe-membrane, amathuluzi ahambayo, njll kufanele kuncishiswe. Izinto ezingabangela ukulimala kulwelwesi olungenakunyakaziswa akufanele zibekwe kulwelwesi noma zithwalwe kulwelwesi ukuze kugwenywe ukulimala ngengozi kulwelwesi.
