Iinethi zokukhupha amanzi ezidityanisiweyo zizinto ezisetyenziswa kakhulu kwiindawo zokulahla inkunkuma, kwiindlela, kwiindonga zangaphakathi zetonela nakwezinye iiprojekthi. Ngoko ke, zeziphi izinto ezisetyenziswa kwiinethi zokukhupha amanzi ezidityanisiweyo?
Inethi yokukhupha amanzi edityanisiweyo yenziwe ngesiseko seplastiki esinemilinganiselo emithathu kunye ne-geotextile evulekayo enamacala amabini. Olu dityaniso aluniki nje kuphela inethi yokukhupha amanzi edityanisiweyo amandla okukhupha amanzi aqinileyo, kodwa luyenza ibe neenzuzo zokuba namandla aphezulu okutsalwa, ukumelana nokugqwala kunye nobomi obude benkonzo.
1. Isiseko seplastiki se-mesh yinxalenye ephambili yenethi yokukhupha amanzi edibeneyo. Yenziwe nge-polyethylene enoxinano oluphezulu (i-HDPE) kwaye icutshungulwa ngenkqubo ekhethekileyo yokubumba i-extrusion. Le siseko se-mesh inesakhiwo esikhethekileyo esimaleko amathathu. Iimbambo eziphakathi ziqinile kwaye zilungelelaniswe ngokude ukuze zenze umjelo wokukhupha amanzi; iimbambo ezicwangciswe ngokunqamlezayo phezulu nasezantsi zenza inkxaso yokuthintela i-geotextile ukuba ingangeni kwi-drainage channel. Nokuba phantsi kwemithwalo ephezulu kakhulu, isiseko seplastiki se-mesh sinokugcina ukusebenza okuphezulu kokukhupha amanzi. Amandla okuxinana okude nokunqamlezayo kunye namandla okucinezela esiseko seplastiki se-mesh aphezulu, anokuqinisekisa uzinzo kunye nokuthembeka kwenethi yokukhupha amanzi edibeneyo ngexesha lokusetyenziswa ixesha elide.
2. I-geotextile evulekayo yenye into ebalulekileyo kwi-composite drainage net. Ngokuqhelekileyo isebenzisa izinto ezifana nelaphu le-polyester filament, ilaphu le-polyester staple fiber okanye i-polypropylene staple fiber cloth. Umsebenzi ophambili we-geotextile kukucoca ukungcola, ukuqinisekisa ukuhamba kakuhle kwe-net core, kunye nokukhupha amanzi ngexesha. I-geotextile ingadityaniswa ngokuqinileyo ne-plastic net core ukwenza isakhiwo esidibeneyo sokukhupha amanzi, esinokuphucula ukusebenza kwe-drainage net kunye nobomi benkonzo ye-composite drainage net.
3. Ukongeza kwezi zinto zimbini ziphambili zingasentla, inethi yokukhupha amanzi edityanisiweyo inokwenziwa ngokwezifiso ngokweemfuno zabathengi ngexesha lenkqubo yemveliso. Umzekelo, i-geotextile edityanisiweyo kumacala omabini ingaba yilaphu le-filament, ilaphu elifutshane le-filament, ilaphu eliluhlaza okanye ilaphu elimnyama. Oku kuguquguquka kuvumela inethi yokukhupha amanzi edityanisiweyo ukuba ilungelelanise ngcono neemfuno zeeprojekthi ezahlukeneyo kwaye iphucule ukusebenza kunye neenzuzo zeprojekthi iyonke.
Inethi yokukhupha amanzi edibeneyo ingasetyenziswa kwiindawo ezininzi ezifana neendawo zokulahla inkunkuma, iibhedi zendlela, kunye neendonga zangaphakathi zetonela. Ayinakukhupha amanzi aqokelelweyo phakathi kwesiseko kunye nesiseko esingaphantsi komhlaba, ivale amanzi e-capillary, kodwa ikwaphucula amandla okuxhasa isiseko kwaye yandise ubomi benkonzo yendlela. Ngaphezu koko, inezibonelelo zokwakha okulula, ixesha elifutshane lokwakha kunye neendleko ezincitshisiweyo.
Njengoko kunokubonwa koku kungasentla, inethi yokukhupha amanzi edityanisiweyo yenziwe ngezinto ezimbini: isiseko seplastiki esinemilinganiselo emithathu kunye ne-geotextile ekwaziyo ukungena emanzini ebotshelelwe emacaleni amabini. Ke ngoko, ukusebenza kwayo kokukhupha amanzi kulungile kakhulu kwaye ingasetyenziswa kwiiprojekthi ezinkulu.
