Kaho ea Geocomposite
Tlhaloso ea Sehlahisoa
Khamphani ea rona ke e 'ngoe ea baetsi le barekisi ba ka sehloohong ba geocomposite Chaena. Re etsa, re rala le ho fana ka lihlahisoa tsa geocomposites le lits'ebeletso tsa tsona tsa ho kenya.

Kenyelletso ea Kaho ea Geocomposite (e qotsitsoeng ho Wikipedia)
Filosofi ea mantlha ea thepa ea geocomposite (kaho) ke ho kopanya likarolo tse ntle ka ho fetisisa tsa lisebelisoa tse fapaneng ka tsela eo lits'ebetso tse ikhethileng li sebetsanoang le tsona ka mokhoa o nepahetseng le ka litšenyehelo tse tlase. Kahoo, karo-karolelano ea melemo / litšenyehelo e eketsoa. Li-geocomposites tse joalo hangata e tla ba lisebelisoa tsa geosynthetic, empa eseng kamehla. Maemong a mang ho ka ba molemo haholo ho sebelisa thepa e sa sebetseng e nang le geosynthetic bakeng sa ts'ebetso e nepahetseng le/kapa litšenyehelo tse tlase.
Ho na le mesebetsi e mehlano ea mantlha e ka fanoang: karohano, matlafatso, tlhoekiso, drainage, le ho thibela.
Khamphani ea rona e ka hlahisa lisebelisoa tse 3 tse latelang tsa kaho ea geocomposite mme re ntse re na le liteishene tsa ho fana ka mefuta e meng ea thepa ea kaho ea geocomposite. Ho feta moo, re ka fana ka ts'ebeletso ea ts'ebetso ea geocomposite ka thoko kapa hammoho le phepelo ea thepa ea rona.
Geocomposite letsopa liner
E entsoe ke geosynthetic nonwoven geotextile, bentonite phofo, geotextile e lohiloeng. Bentonite ke letsopa le nang le thepa e ntle ea ho atolosa 'me li tla theha lesela le lekaneng la ho itšireletsa ha li kopana le metsi kapa mongobo o mongata oa metsi. Ka linako tse ling, ho ntlafatsa bokhoni ba ho thibela metsi ba kobo ena ea bentonite, letlapa la hdpe la geomembrane le tla ekeletsoa ho hlahisa mofuta o mong oa sehlahisoa sena, se bitsoang geomembrane clay liner (eo hape e bitsoang hdpe geosynthetic liner, geomembrane bentonite, gcl geomembrane, composite hdpe bentonite membrane) . Lesela lena la letsopa la geocomposite le ka sebelisoa litsing tsa litšila, matangoaneng, matšeng a maiketsetso kapa libakeng tse ling tse hlokang taolo ea khoholeho kapa ts'ebetso ea ho thibela metsi.

Ke thepa ea geocomposite e entsoeng ke geotextile le geomembrane. E na le ts'ebetso ea mantlha ea ho boloka (ho se khonehe) ha geomembrane hape e na le mesebetsi ea mantlha ea karohano, ho sefa, drainage, ho matlafatsa geotextile.

E ka sebelisoa mesebetsing e mengata ea boenjiniere joalo ka letamo le letamo le thibelang metsi, sets'oants'o sa lithōle, matamo a metsi a thibelang metsi, joalo-joalo.
