Chophimba chapamwamba cha bulangeti chotchinga madzi ndi membrane ndi filimu ya polyethylene (HDPE) yochuluka kwambiri, ndipo pansi pake ndi nsalu yopanda nsalu. filimu ya polyethylene yapamwamba kwambiri (HDPE) imamatiridwapo. Chofunda chopanda madzi cha Bentonite chili ndi mphamvu zolimba zamadzi komanso zotsutsana ndi madzi kuposa bulangeti wamba lopanda madzi la bentonite. Njira yopanda madzi ndi yakuti bentonite particles zimatupa ndi madzi kupanga yunifolomu colloidal system. Pansi pa zoletsedwa za zigawo ziwiri za geotextiles, bentonite imakula kuchoka kuchisokonezo kupita ku dongosolo. Chotsatira cha kuyamwa madzi mosalekeza ndi kukulitsa ndi kupanga bentonite wosanjikiza wokha wandiweyani. , kuti ikhale ndi mphamvu yoletsa madzi.
Maonekedwe a bulangeti lopanda madzi lokutidwa ndi filimu:
1. Ili ndi ntchito yabwino kwambiri yopanda madzi komanso yotsutsa-seepage, kupanikizika kwa anti-seepage hydrostatic kumatha kufika kupitirira 1.0MPa, ndipo mphamvu ya permeability ndi 5 × 10-9cm / s. Bentonite ndi chilengedwe chakuthupi, chomwe sichidzakumana ndi ukalamba ndipo chimakhala chokhazikika; Chilichonse choyipa chomwe chingawononge chilengedwe ndi chinthu chosawononga chilengedwe
2. Zili ndi zizindikiro zonse za zipangizo za geotextile, monga kupatukana, kulimbikitsa, chitetezo, kusefera, ndi zina zotero. Kumangako ndi kosavuta komanso kosawerengeka ndi kutentha kwa chilengedwe, komanso kumangidwanso pansi pa 0 ° C. Pomanga, ingoyalani bulangeti lopanda madzi la GCL pansi, ndikulikonza ndi misomali ndi zochapira pomanga pakhonde kapena potsetsereka, ndikuchikulunga ngati pakufunika.
3. Zosavuta kukonza; ngakhale pambuyo pa kumangidwa kwa madzi (seepage) kumalizidwa, ngati wosanjikiza madzi akuwonongeka mwangozi, malinga ngati gawo lowonongeka limangokonzedwanso, ntchito yamadzi imatha kubwezeretsedwanso monga momwe zinalili.
4. Chiŵerengero cha ntchito-mtengo ndi chokwera kwambiri, ndipo ntchito ndi yotakata kwambiri.
5. M'lifupi mwa mankhwalawa amatha kufika mamita 6, omwe amafanana ndi zomwe geotextile (membrane) yapadziko lonse lapansi, yomwe imapangitsa kuti ntchito yomanga ikhale yabwino.
6. Ndikoyenera kuchitira anti-seepage ndi anti-seepage chithandizo m'madera omwe ali ndi zofunikira zamadzimadzi komanso zotsutsana ndi zowonongeka, monga: tunnels, subways, zipinda zapansi, ndime zapansi, nyumba zosiyanasiyana zapansi ndi mapulojekiti amadzi omwe ali ndi madzi olemera apansi.
