Yiziphi izindlela zokudonsa amanzi emiseleni yokudonsa amanzi esezakhiwe?

Iziteshi zokudonsa amanzi ezakhiwe ngaphambilini zivame kakhulu ekuphileni kwansuku zonke futhi zidlala indima ebalulekile.Kodwa-ke, abantu abaningi abazazi izindlela zokukhipha amanzi emiseleni esele yakhiwe.Namuhla, abakhiqizi beziteshi zokudonsa amanzi bazokwabelana ngezindlela ezimbalwa zokudonsa amanzi ukuze uthole inkomba yakho.

1. Imisele yokukhipha amanzi evulekile: Gcoba amazinga ahlukahlukene emisele yokudonsa amanzi ukuze wenze inethiwekhi yemisele.Amanzi ageleza esuka emiseleni yasendle (imisele yokuswakama kwenhlabathi, imisele, imisele yezolimo yerayisi) eya emiseleni yokuthutha (imisele emikhulu, imisele yamagatsha, imisele yeziqu), futhi ekugcineni ayongena ezindaweni zokulahla (imifula, amachibi, izilwandle).
2. Imisele yokukhipha amanzi evulekile engenawo amapuleti ekhava: Imisele yokukhipha amanzi evulekile engenawo amapuleti ekhava ngokuvamile afakwa eduze komjikelezo wezindonga zangaphandle zezindlu zangaphansi.Ububanzi bomsele wokudonsa amanzi ngokuvamile buba ngu-100mm.Ngesikhathi sokwakhiwa kwesitezi esingaphansi, ukubeka nokuhlela kufanele kwenziwe kuqala, kulandelwe ukwakhiwa kwe-formwork.

Ngemuva kokuthi ukhonkolo uthululwe phansi, udaka lwesimende oluxutshwe ngaphambili oluyi-20mm lwe-M20 (oluxutshwe no-5% lwempushana yokuvimbela amanzi) kufanele lufakwe phansi kanye nezindonga eziseceleni zomsele.Ngesikhathi esifanayo, i-slope kufanele idalwe phansi komsele nge-gradient ye-0.5%.

Uma usebenzisa iziteshi zokudonsa amanzi ezakhiwe ngaphambili, kubalulekile ukunamathela emiyalweni efanele kanye nezidingo zokulondoloza ukuze kuqinisekiswe ukusebenza kahle okuqhubekayo kohlelo lokudonsa amanzi.Ngaphambi kokuthenga nokufaka, xhumana nonjiniyela be-drainage noma abahlinzeki ukuze uqonde izindlela ezithile zokusebenzisa kanye nezindlela zokuphepha zokunakekela imigudu yokudonsa amanzi.
