Njengamanje, izwe lami lisebenzisa ukushiswa kwemfucuza yasekhaya, futhi ukulahlwa kwemfucuza okuyisisekelo kuzokwehla kancane kancane. Kodwa idolobha ngalinye lidinga okungenani indawo yokulahlwa imfucumfucu eyodwa yokulahla okuphuthumayo kanye nendawo yokulahla umlotha yokushiswa. Ngakolunye uhlangothi, njengamanje kunenqwaba yezindawo zokulahla imfucuza eqinile ezigcwalisiwe futhi ezidinga ukuvalwa. Ngakho-ke, esikhathini esizayo, i-geosynthetics izoba namathemba amahle emakethe ekuvaleni kwezindawo zokulahla imfucuza eqinile kanye nokumbozwa kwesikhashana kwezindawo zokulahla imfucumfucu ezisebenza.
Okubizwa ngekhava yokuvala kusho ukuthi lapho indawo yokulahla imfucumfucu eqinile igcwaliswa, isakhiwo sokumboza esibalulekile sidinga ukwakhiwa phezu kwaso ukuze kuvinjelwe ukungena kwamanzi emvula kanye nokuchichima kwegesi yokulahla, futhi izitshalo zingatshalwa ukuze zitshale futhi zibuyiselwe. Kunezinhlobo ezintathu eziyinhloko zezinto ze-geosynthetic ezisetshenziswa kukhava yasensimini: i-low density polyethylene (LDPE) geomembrane, ingubo ye-bentonite engangeni manzi kanye nenethi yokukhipha amanzi eyinhlanganisela. Phakathi kwazo, i-LDPE geomembrane ine-ductility enhle, akulula ukudatshulwa, futhi ingadlala indima enhle e-anti-seepage kanye ne-air-sealing. Izakhiwo zokuvimbela i-anti-seepage zengubo ye-bentonite engenamanzi nazo zinhle kakhulu. Uma kuqhathaniswa ne-geomembrane, ngeke iwunqamule ngokuphelele umhwamuko wamanzi ngaphansi kongqimba oluyisimbozo, okusiza kakhulu ekukhuleni kwezimila.
Ukumbozwa kwesikhashana kwezindawo zokulahla imfucuza eqinile esebenza emsebenzini ukumboza izindawo zikadoti eziveziwe nge-geosynthetics ezindaweni ezingagcwalisiwe okwesikhashana ukuze kuncishiswe ukungena kwamanzi emvula nokuchichima kwegesi yokulahla. Ikhava yesikhashana ibuye isetshenziswe ngokujwayelekile kumaphrojekthi wokwelapha indawo yokungcola ukuze kuvinjelwe amagesi ayingozi aguquguqukayo ukuthi angaphunyuli emkhathini. Ezinsukwini zakuqala, oseyili, amafilimu, njll. babevame ukusetshenziselwa ukumbozwa okwesikhashana, kodwa izinkinga ezifana nomphumela ongemuhle wokunqanda ukubola kanye nomphumela wokuvalwa komoya kanye nokudabuka kalula kwamashisela kwakujwayele ukwenzeka. Njengamanje, izindawo zokulahla imfucumfucu zinezidingo eziphakeme neziphakeme zokulahlwa komhlaba okuvaliwe. Ezinye izindawo zokulahla imfucumfucu zisebenzisa i-HDPE geomembrane ewugqinsi engu-1mm ukuze ifakwe isikhashana. Umphumela wokuvala phansi ungcono.
