Ungqimba olungaphezulu lwengubo evikela amanzi embozwe ulwelwesi ifilimu ye-polyethylene (i-HDPE) enomthamo omkhulu, kanti ungqimba olungezansi yindwangu engalukiwe. Kunamathiselwe ungqimba lwefilimu ye-polyethylene (i-HDPE) ephezulu kakhulu. Ingubo ye-bentonite engangeni manzi inekhono eliqinile lokungangeni manzi kanye ne-anti-seepage kunengubo evamile ye-bentonite engenamanzi. Indlela engenawo amanzi iwukuthi izinhlayiya ze-bentonite zigcwala amanzi ukuze zenze uhlelo lwe-colloidal olufanayo. Ngaphansi kokuvinjelwa kwezingqimba ezimbili ze-geotextiles, i-bentonite inwebeka kusukela ekuhlakazeni kuya ekuhlelekeni. Umphumela wokumuncwa kwamanzi okuqhubekayo nokwandisa ukwenza ungqimba lwe-bentonite ngokwalo lube lukhuni. , ukuze kube nomphumela wokungangeni kwamanzi.
Izici ezibonakalayo zengubo yokulala engenamanzi ehlanganiswe nefilimu:
1. Inokusebenza okuhle kakhulu kokungangeni kwamanzi nokuphikisana nokubona, ingcindezi ye-hydrostatic ephikisana ne-seepage ingafinyelela ngaphezu kwe-1.0MPa, futhi i-permeability coefficient ingu-5 × 10-9cm/s. I-Bentonite iyinto engokwemvelo ye-inorganic, engeke ibhekane nokuguga futhi inokuqina okuhle; Noma imuphi umthelela omubi endaweni ezungezile uyinto ehambisana nemvelo
2. Inazo zonke izici zezinto ze-geotextile, njengokuhlukanisa, ukuqinisa, ukuvikelwa, ukuhlunga, njll. Ukwakhiwa kulula futhi akunqunyelwe izinga lokushisa lendawo yokwakha, futhi kungakhiwa ngaphansi kwe-0 ° C. Ngesikhathi sokwakha, vele wendlala ingubo yokulala ye-GCL engangeni manzi phansi, uyilungise ngezipikili namawasha lapho wakha ku-facade noma emthambekeni, futhi uyibophe njengoba kudingeka.
3. Kulula ukulungisa; ngisho nangemva kokuqedwa kokwakhiwa kwamanzi (i-seepage), uma ungqimba olungangeni manzi lonakaliswe ngephutha, inqobo nje uma ingxenye eyonakele imane ilungiswe, ukusebenza okungangeni kwamanzi kungabuyiselwa njengoba kwakunjalo.
4. Isilinganiso sokusebenza-intengo siphezulu uma kuqhathaniswa, futhi ukusetshenziswa kubanzi kakhulu.
5. Ububanzi bomkhiqizo bungafinyelela kumamitha angu-6, okuhambisana nokucaciswa kwe-geotextile yamazwe ngamazwe (i-membrane), ethuthukisa kakhulu ukusebenza kahle kokwakhiwa.
6. Ifaneleka ekwelapheni okunqanda ukubola kanye nokunqanda ukuvuleka emkhakheni wezidingo eziphakeme zokungangeni kwamanzi kanye nokunqanda amanzi, njengalezi: imigudu, imigwaqo engaphansi komhlaba, amagumbi angaphansi, amaphaseji angaphansi komhlaba, izakhiwo ezihlukahlukene ezingaphansi komhlaba kanye namaphrojekthi we-waterscape anemithombo yamanzi angaphansi komhlaba anothile.
