Inethi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu iyinto yokudonsa amanzi evame ukusetshenziswa kumaphrojekthi amakhulu. Ngakho-ke, ikhiqizwa kanjani?
1. Ukukhethwa kwezinto ezingavuthiwe kanye nokwelashwa kwangaphambili
Izinto zokusetshenziswa eziyinhloko zenethi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu yi-polyethylene ephezulu (i-HDPE). Ngaphambi kokukhiqizwa, izinto zokusetshenziswa ze-HDPE kumele zihlolwe ngokucophelela ukuqinisekisa ukuthi ubumsulwa bazo kanye nekhwalithi yazo kuyahlangabezana nezindinganiso zokukhiqiza. Ngemuva kwalokho izinto zokusetshenziswa ziphathwa kusengaphambili ngokomiswa, ukushiswa kusengaphambili, njll. ukuze kususwe umswakama wangaphakathi kanye nokungcola ukuze kubekwe isisekelo esiqinile sokubumba okulandelayo kwe-extrusion.
2. Inqubo yokubumba i-extrusion
Ukubumba i-extrusion kuyisixhumanisi esibalulekile ekukhiqizweni kwamanethi okudonsa amanzi ahlanganisiwe anezinhlangothi ezintathu. Kulesi sigaba, izinto zokusetshenziswa ze-HDPE ezilungisiwe ngaphambilini zithunyelwa kumkhiphi ochwepheshe, futhi izinto zokusetshenziswa ziyancibilikiswa futhi zikhishwe ngokulinganayo endaweni yokushisa ephezulu kanye nendawo yokucindezela okuphezulu. Ngesikhathi senqubo yokukhipha, ikhanda le-die eliklanywe ngokukhethekile lisetshenziswa ukulawula ngokunembile ukuma kwe-extrusion kanye nosayizi wezimbambo ukuze kwakhiwe isakhiwo sezimbambo ezintathu esine-engeli ethile kanye nesikhala. Lezi zimbambo ezintathu zihlelwe ngephethini ethile ukuze kwakhiwe isakhiwo sendawo esinezinhlangothi ezintathu. Ubambo oluphakathi luqinile futhi lungakha isiteshi sokukhipha amanzi esisebenzayo, kuyilapho izimbambo ezihlelwe ngokuphambene zidlala indima esekelayo, engavimbela i-geotextile ukuthi ingene emgudwini wokukhipha amanzi, iqinisekise ukusebenza kahle kokukhipha amanzi okuzinzile nokuthembekile.
3. Ukubopha kwe-geotextile okuhlanganisiwe
I-geonet core enezinhlangothi ezintathu ngemuva kokubumba i-extrusion kumele ihlanganiswe ne-geotextile evulekayo enezinhlangothi ezimbili. Le nqubo idinga ukuthi inhlaka isetshenziswe ngokulinganayo ebusweni be-net core, bese i-geotextile ifakwa ngokunembile, bese lokhu kokubili kuhlanganiswa ngokuqinile ngokucindezela okushisayo noma ukubopha ngamakhemikhali. I-composite three-dimensional drainage net inetha ayigcini nje ngokudla i-drainage performance ye-geonet, kodwa futhi ihlanganisa imisebenzi yokulwa nokuhlunga nokuvikela ye-geotextile, yakha ukusebenza okuphelele "kokuvikela ukuhlunga nokukhipha amanzi".
4. Ukuhlolwa kwekhwalithi kanye nokupakishwa komkhiqizo okuqediwe
Inethi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu kumele ihlolwe ikhwalithi ngokuqinile, okuhlanganisa ukuhlolwa kokubukeka, ukulinganiswa kosayizi, ukuhlolwa kokusebenza kanye nezinye izixhumanisi ukuqinisekisa ukuthi umkhiqizo ngamunye uhlangabezana nezindinganiso zemboni kanye nezidingo zamakhasimende. Ngemva kokudlula ukuhlolwa, inethi yokukhipha amanzi ipakishwa ngokucophelela ukuze kuvinjelwe umonakalo ngesikhathi sokuthuthwa nokugcinwa. Ukukhethwa kwezinto zokupakisha kufanele futhi kugxile ekuvikelweni kwemvelo nasekuqineni ukuqinisekisa ukuthi umkhiqizo ungalethwa kumakhasimende ngokuphephile nangokuphelele.
