Geomembrane ya polyethylene yochuluka kwambiri imagwiritsidwa ntchito makamaka m'malo otaya zinyalala, nyanja zam'madzi, ndi maiwe.Mizinda yakumidzi yakumidzi imayikidwa pansi, ndipo mapangidwe onse a denga la membrane amakhala ndi makulidwe a chitetezo, kotero kuti chiwopsezo cha kutulutsa sichapamwamba.Komabe, kupaka makoma a konkire ndi ntchito yoyamba yomanga, ndipo pali zovuta zazikulu ziwiri pomanga: imodzi ndiyo kuyika nembanemba yosasunthika pakhoma la nyumba yosungiramo zinthu zotalika mamita 4.The nembanemba impermeable nthawi yomweyo zimatengera mphamvu ndi madzi oipa, choncho ayenera Chotsani zofooka zina monga in-situ nkhawa ndi kubala mapindikidwe;2. Kusasunthika kwa pulojekitiyi kumatchulidwa ngati Kalasi I, ndipo cholinga chachikulu cha dongosolo la mapangidwe ndi kuthetsa vuto la madzi owonongeka a fakitale ndi madzi amchere ambiri.Kudontha kukachitika kubisala, pamapeto pake kumatuluka, zomwe zimapangitsa kuti madzi aipitsidwe, zomwe zimakhudza kwambiri anthu, ndipo zimawononga ndalama zambiri kuti mupeze kutayikira ndikukonza.Chifukwa chake, pakuyika ma membrane odana ndi seepage, kasamalidwe kabwino kamayenera kuphatikizidwa mu ntchito yofunika kwambiri.
Monga gwero lofunikira lamadzi amvula lamagetsi apakatikati pama projekiti amadzi akumwa a m'tawuni, matanki osungira madzi amakhala ndi gawo lofunikira kwambiri.Chifukwa chake, ma projekiti ambiri osungira madzi okhala ndi fakitale ya geomembrane yokhala ndi mtengo wosanjikiza madzi monga momwe machitidwe ake amapangidwira ndikumangidwa.Ngakhale kalasi ya uinjiniya ndi kalasi yomanga ndi yotsika, ndi ya sitandade 4 ndi masukulu ena a 4 mpaka 5 ang'onoang'ono komanso apakati, koma chifukwa chosungiracho chili m'matauni (tauni) ndi madera akumidzi, ngati kutayikira ndi kusalinganika kwamtunda kuli. Zimayambitsa, zitha kuyambitsa chitetezo monga kugwa Ngozi idzayambika.
Makhalidwe ofunika a geomembrane
1. Mkulu compressive mphamvu ndi ductility wabwino;
2. Good wosanjikiza madzi wosanjikiza ntchito;
3. Zomangamanga zosavuta, zopepuka, komanso zosavuta kuyenda;
4. Zabwino kwambiri zakuthupi ndi organic mankhwala: HDPE impermeable nembanemba ali odana ndi ukalamba, odana ndi ultraviolet, kupirira bwino, puncture resistance, low ductility, pang'ono matenthedwe mapindikidwe, kwambiri organic mankhwala kudalirika, mkulu ndi otsika kutentha kukana, Kukaniza leaching, mafuta ndi malasha phula, asidi, alkali, mchere, ndi njira zina mankhwala;
5. Zotsika mtengo komanso zopindulitsa zambiri zachuma;
6. Chitetezo cha chilengedwe: Zida zomwe zimasankhidwa kuti zikhale ndi nembanemba ya polyethylene yosasunthika kwambiri ndizopanda poizoni zatsopano zowononga chilengedwe.Mfundo yofunikira ya nembanemba yopanda madzi ndikuti kusintha kwanthawi zonse sikungayambitse zinthu zovulaza.Ndi chisankho chabwino kwambiri pakuweta kosamalira zachilengedwe.
