Ungqimba olungaphezulu lwengubo yokulala engangeni manzi eboshiwe ifilimu ye-polyethylene (i-HDPE) enomthamo omkhulu futhi ungqimba olungezansi yindwangu engalukiwe. Ingubo ye-sodium bentonite engenamanzi enomphumela ongcono wokungenwa kwamanzi igxilile phakathi kwama-geotextiles anamandla amakhulu kusetshenziswa indlela ekhethekile yokubhoboza inaliti bese ibekwa kwendwangu engalukiwe. Isendlalelo sefilimu ye-polyethylene (i-HDPE) ephezulu kakhulu inamathele kuso. Ingubo yokulala ye-bentonite engangeni manzi inamandla aqinile angangeni manzi futhi amelana ne-seepage kunengubo evamile ye-bentonite engenamanzi. Indlela yokuvimbela amanzi iwukuthi izinhlayiya ze-bentonite zanda lapho zivezwa emanzini, zakha uhlelo lwe-colloid olufanayo. Ngaphansi kokuvinjelwa kwezendlalelo ezimbili ze-geotextile, i-bentonite inwebeka isuka ekuphazamisekeni iye ekuhlelekeni. Umphumela wokumuncwa kwamanzi okuqhubekayo nokwandisa ukwenza ungqimba lwe-bentonite ngokwalo lube lukhuni. , ngaleyo ndlela ibe nomphumela wokungangeni kwamanzi.
Izici ezingokomzimba zengubo engangeni amanzi eboshiwe:
1. Inezici ezinhle kakhulu zokungangeni kwamanzi kanye ne-anti-seepage, i-anti-seepage hydrostatic pressure ingafinyelela ngaphezu kwe-1.0MPa, futhi i-permeability coefficient ingu-5 × 10-9cm/s. I-Bentonite iyinto yemvelo ye-inorganic engeke ibhekane nokuguga futhi inokuqina okuhle; futhi ngeke Noma yimuphi umthelela omubi emvelweni uyinto ehambisana nemvelo
2. Inazo zonke izici zezinto ze-geotextile, njengokuhlukanisa, ukuqinisa, ukuvikela, ukuhlunga, njll. Kulula ukwakha futhi akuvinjelwa ukushisa kwendawo yokwakha. Ingabuye yakhiwe ngaphansi kuka-0℃. Ngesikhathi sokwakha, udinga kuphela ukubeka ingubo ye-GCL engangeni manzi phansi. Lapho wakha ku-facade noma emthambekeni, yilungise ngezinzipho namawasha, futhi uyigqagqene njengoba kudingeka.
3. Kulula ukulungisa; ngisho nangemva kokuba ukwakhiwa kokuvimbela amanzi (i-seepage) sekuqediwe, uma ungqimba lokuvimbela amanzi lonakaliswa ngengozi, inqobo nje uma ingxenye eyonakele imane ilungiswe, ukusebenza okuqinile kokuvimbela amanzi kungabuyiselwa.
4. Isilinganiso sentengo yokusebenza siphezulu uma kuqhathaniswa futhi sinokusetshenziswa okubanzi okubanzi.
5. Ububanzi bomkhiqizo bungafinyelela kumamitha angu-6, okuhambisana nokucaciswa kwe-geotextile (membrane) yamazwe ngamazwe, ukuthuthukisa kakhulu ukusebenza kahle kokwakhiwa.
6. Ilungele ukwelashwa okunqanda ukubola nokuvuza ezindaweni ezinezidingo eziphakeme zokuvimbela amanzi kanye ne-anti-sepage, njengemigudu, imigwaqo engaphansi komhlaba, amagumbi angaphansi, amaphaseji angaphansi komhlaba, izakhiwo ezihlukahlukene ezingaphansi komhlaba kanye namaphrojekthi we-waterscape anemithombo yamanzi angaphansi komhlaba anothile.
