Inethi yokukhupha amanzi edityanisiweyo enemilinganiselo emithathu yindlela yokukhupha amanzi esetyenziswa kakhulu kwiiprojekthi ezinkulu. Ngoko ke, iveliswa njani?
1. Ukukhethwa kwezinto eziluhlaza kunye nonyango lwangaphambi kokuba zisetyenziswe
Izinto ezisisiseko zokucoca amanzi kwi-composite enemilinganiselo emithathu yi-high-density polyethylene (HDPE). Ngaphambi kokuveliswa, izinto ezikrwada ze-HDPE kufuneka zihlolwe ngokungqongqo ukuqinisekisa ukuba ubunyulu kunye nomgangatho wazo ziyahlangabezana nemigangatho yemveliso. Emva koko izinto ezikrwada zilungiswa kwangaphambili ngokomiswa, ukufudumeza kwangaphambili, njl.njl. ukuze kususwe umswakama wangaphakathi kunye nokungcola ukuze kubekwe isiseko esiqinileyo sokubumba okulandelayo kwe-extrusion.
2. Inkqubo yokubumba i-extrusion
Ukubumba i-extrusion yikhonkco eliphambili ekuvelisweni kwe-three-dimensional composite drainage nets. Kweli nqanaba, izinto eziluhlaza ze-HDPE ezilungisiweyo zithunyelwa kwi-extruder echwepheshileyo, kwaye izinto eziluhlaza ziyanyibilika kwaye zikhutshwe ngokulinganayo kwindawo enobushushu obuphezulu kunye noxinzelelo oluphezulu. Ngexesha lenkqubo yokukhupha, intloko ye-die eyenzelwe ngokukodwa isetyenziselwa ukulawula ngokuchanekileyo imo ye-extrusion kunye nobukhulu beembambo ukwenza isakhiwo seembambo ezintathu esine-engile ethile kunye nesithuba. Ezi mbambo zintathu zicwangciswe ngendlela ethile ukwenza isakhiwo sendawo esineembambo ezintathu. Umbambo ophakathi uqinile kwaye unokwenza umjelo wokukhupha amanzi osebenzayo, ngelixa iimbambo ezicwangcisiweyo zidlala indima exhasayo, enokuthintela i-geotextile ukuba ingene kumjelo wokukhupha amanzi, ukuqinisekisa ukusebenza kokukhupha amanzi okuzinzileyo nokuthembekileyo.
3. Ukubopha i-geotextile edibeneyo
Isiseko se-geonet esinemilinganiselo emithathu emva kokubumba i-extrusion kufuneka sidityaniswe ne-geotextile enemiphetho emibini. Le nkqubo ifuna ukuba i-adhesive isetyenziswe ngokulinganayo kumphezulu wesiseko se-net, kwaye emva koko i-geotextile ifakwe ngokuchanekileyo, kwaye zombini zidityaniswe ngokuqinileyo ngokucinezela okushushu okanye ukubophelela ngamakhemikhali. I-composite three-dimensional drainage net ayizuzi nje kuphela ukusebenza kwe-drainage ye-geonet, kodwa ikwadibanisa imisebenzi yokulwa nokuhluza kunye nokukhusela ye-geotextile, yenza ukusebenza okubanzi "kokukhusela ukuhluza-ukukhupha amanzi".
4. Ukuhlolwa komgangatho kunye nokupakishwa kwemveliso egqityiweyo
Inethi yokukhupha amanzi edityanisiweyo enemilinganiselo emithathu kufuneka ihlolwe ngokungqongqo umgangatho, kubandakanya ukuhlolwa kwembonakalo, ukulinganiswa kobungakanani, uvavanyo lokusebenza kunye nezinye iikhonkco ukuqinisekisa ukuba imveliso nganye iyahlangabezana nemigangatho yoshishino kunye neemfuno zabathengi. Emva kokuphumelela kuhlolo, inethi yokukhupha amanzi ipakishwa ngononophelo ukuthintela umonakalo ngexesha lokuthuthwa nokugcinwa. Ukukhethwa kwezinto zokupakisha kufuneka kugxile kukhuseleko lokusingqongileyo kunye nokuqina ukuqinisekisa ukuba imveliso inokuhanjiswa kubathengi ngokukhuselekileyo nangokupheleleyo.
