Igice cyo hejuru cyikibiriti gitwikiriwe namazi adafite amazi ni firime yuzuye ya polyethylene (HDPE), naho igice cyo hepfo nigitambara kidoda. Igice cya firime yuzuye ya polyethylene (HDPE) yometseho. Igipangu cya Bentonite kitagira amazi gifite imbaraga zidafite amazi kandi zirwanya seepage kuruta igipangu gisanzwe cya bentonite. Uburyo butarinda amazi ni uko ibice bya bentonite byabyimbye n'amazi kugirango bigire sisitemu imwe. Mugihe cyo kubuza ibice bibiri bya geotextile, bentonite yaguka kuva mukaduruvayo. Igisubizo cyo gukomeza kwinjiza amazi no kwaguka nugukora igipimo cya bentonite ubwacyo. , kugirango ugire ingaruka zidafite amazi.
Ibiranga umubiri biranga firime isize amazi adafite amazi:
1. Ifite ibikorwa byiza bitarinda amazi na anti-seepage, umuvuduko wa hydrostatike anti-seepage urashobora kugera kuri 1.0MPa, kandi coefficente ya permeability ni 5 × 10-9cm / s. Bentonite ni ibintu bisanzwe bidasanzwe, bitazajya bisaza kandi bifite igihe kirekire; Ingaruka mbi zose kubidukikije ni ibikoresho byangiza ibidukikije
2. Ifite ibintu byose biranga ibikoresho bya geotextile, nko gutandukana, gushimangira, kurinda, kuyungurura, nibindi. Kubaka biroroshye kandi ntibigarukira kubushyuhe bwibidukikije byubaka, kandi birashobora no kubakwa munsi ya 0 ° C. Mugihe cyo kubaka, shyira gusa igipangu kitarimo amazi ya GCL hasi, ugikosore imisumari hamwe nogeshe mugihe wubatse kuruhande cyangwa ahahanamye, hanyuma ukizenguruke nkuko bisabwa.
3. Biroroshye gusana; na nyuma yo kubaka amazi adafite amazi (seepage) arangiye, niba igice kitarimo amazi cyangiritse kubwimpanuka, mugihe igice cyangiritse gisanwe gusa, imikorere idakoresha amazi irashobora kugarurwa nkuko byari bimeze.
4. Igipimo cyibikorwa-igiciro kiri hejuru cyane, kandi ikoreshwa ni ryagutse cyane.
5. Ubugari bwibicuruzwa bushobora kugera kuri metero 6, buhuye nibisobanuro bya geotextile mpuzamahanga (membrane), biteza imbere cyane ubwubatsi.
