Amathuba okuphumelela aphezulu kakhulu uma indawo ifanelekile kodwa siyazi ukuthi lokhu akwenzeki ngaso sonke isikhathi. Kukhona inhlabathi engalingani, eminye ithambeka noma ingenamapayipi amabi, eminye ihlupheka kakhulu kanti eminye inenhlabathi eminyene kakhulu edala udaka oluminyanisa izimpande futhi lungaholela ekufeni kwezitshalo.
Into yokuqala okufanele yenziwe lapho hlela ingadi es hlaziya uhlobo lomhlabathi bese uqinisekisa ukugeleza kwawo. Uma kwenzeka thola izinkinga zamanzi, kumele sithole isisombululo kungenjalo sizoba senkingeni enkulu.
Ngiyazisola ukukutshela ukuthi isixazululo sivela esandleni semisebenzi ethile ngoba kuyadingeka ukwakha isakhiwo esithile esithuthukisa amanzi. Ngalo mqondo, kunezindlela ezimbili ezingenzeka futhi ukhetho kuzodingeka luhlaziye izindleko nezinzuzo.
Ukukhipha okungcwatshwe
Una Isixazululo esingenzeka sokwenza ngcono amanzi enhlabathi engadini ukufaka a uhlelo lokuhambisa amanzi ngaphansi komhlaba, okungukuthi, isakhiwo esingcwatshiwe esinakekela ukukhipha amanzi amaningi.
Okuvame kakhulu ukuthi iyi- inethiwekhi engaphansi komhlaba eyenziwe ngamapayipi lawo angaba ngamasentimitha angaba ngu-40/50 ukujula, atholakala ngokufana futhi ahlukaniswe phakathi kwamamitha amabili kuya kwamathathu. Ukufakwa kudinga umsebenzi othile ngoba ukuthola amashubhu kufanele umbe imisele engu-2 cm ububanzi ebhekele ukwakheka kwamashubhu. Kepha okubaluleke kakhulu ukuthi uhlelo lusebenze ukuthi inethiwekhi kumele ibe nomthambeka owayo ukuze amanzi afinyelele kusuka emapayipini kuya emseleni omkhulu ozoxhunyaniswa nomqoqi wokukhishwa kwamanzi.
Okunye isakhiwo sokuhambisa amanzi esilula ukudala inethiwekhi yemisele emise okwe-herringbone, okungenye yezindlela ezijwayeleke kakhulu zamanzi zokuphuma emipayipini yesibili iye enkabeni. Kungenzeka futhi ukuthi kutholakale ithubhu emaphakathi kolunye lwezinhlangothi zensimu nokuthi amashubhu wesibili ahola amanzi abhekise kuwo ukuze afinyelele ekuphumeni kwawo.
Kuqinile ukudonsa amanzi
Ngenkathi i uhlelo lokuhambisa amanzi ngaphansi komhlaba inikeza isixazululo ngokushesha se- Izinkinga zokukhishwa kwenhlabathi kufanele ube nesabelomali sokufakwa kwayo futhi yingakho kunezinye izixazululo ezingabizi kakhulu zokukhipha phansi njengokwakhiwa kwama-massifs.
Umsebenzi ulula ngoba kufanele nje phakamisa ama-massifs phakathi kuka-20 no-30 cm ukuphakama, kushiya izindlela phakathi kobuningi ukuze amanzi ajikeleze lapho. Ngemuva kwalokho kubekwa ungqimba lwegravel oluzovimba imigwaqo ukuthi ingangeni emanzini.
Kungenzeka wenze umsebenzi ngaphandle kosizo lwangaphandle nangosizo lwe-backhoe ukudala imigwaqo.
