Amathuba okuphumelela aphezulu kakhulu xa umhlaba ulungile kodwa siyazi ukuba oku akusoloko kusenzeka. Kukho imihlaba engalinganiyo, eminye ithambeka okanye ingabi namanzi amdaka, eminye ihlwempuzeke kakhulu kwaye eminye inemihlaba emxinwa kakhulu edala amadama aminxa iingcambu kwaye anokukhokelela ekufeni kwezityalo.
Into yokuqala yokwenza xa cwangcisa igadi es Hlalutya uhlobo lomhlaba kwaye uqinisekise ukuhanjiswa kwawo. Mhlawumbi ku ukufumanisa iingxaki zokuhambisa amanzi, kufuneka sifumane isisombululo kungenjalo siya kuba sengxakini enkulu.
Ndiyazisola ngokunixelela ukuba isisombululo sivela esandleni semisebenzi ethile kuba kuyimfuneko ukwenza ulwakhiwo oluthile oluphucula ukuhambisa amanzi. Ngale ndlela, zimbini iindlela ezinokubakho kwaye ukhetho kuya kufuneka luhlalutye iindleko kunye nezibonelelo.
Umsele wokungcwaba
Omnye Isisombululo esinokwenzeka sokuphucula umjelo womhlaba wegadi ukufaka i inkqubo yokuhambisa amanzi phantsi komhlabaOko kukuthi, isakhiwo esingcwatyelweyo esijongana nokukhupha amanzi agqithisileyo.
Eyona nto ixhaphakileyo kukuba yi uthungelwano olungaphantsi komhlaba olwenziwe ngemibhobho ezi malunga neesentimitha ezingama-40/50 ubunzulu, ezibekwe ngokulinganayo kunye nokwahlula phakathi kwe-2 kunye ne-3 yeemitha. Ukufakwa kufuna umsebenzi othile kuba ukuze ufumane iityhubhu kufuneka umbe imisele engama-59 cm ububanzi ejongene nokugcina iityhubhu. Kodwa eyona nto ibaluleke kakhulu ekusebenzeni kwale nkqubo kukuba uthungelwano kufuneka lube nokuhla kwethambeka ukuze amanzi afike ukusuka kwimibhobho ukuya kumjelo ophambili oya kuthi uqhagamshelwe kwindawo yokuqokelela amanzi.
Okunye ulwakhiwo olulula lokungcwaba Kukudala uthungelwano lwemijelo emile okwe-herringbone, enye yezona zinto ziyilo oluqhelekileyo lwamanzi okuphuma kwimibhobho yesibini ukuya embindini. Kuyenzeka ukuba ufumane ityhubhu esembindini kwelinye lamacala egadi kwaye iityhubhu zesekondari zikhokelela amanzi aya kuwo ukuze afezekise ukuphuma kwawo.
Iqinile kumjelo wamanzi
Ngoxa i inkqubo yokuhambisa amanzi phantsi komhlaba inikeza isisombululo kwangoko iingxaki zokuhambisa amanzi emhlabeni Kuya kufuneka ube nohlahlo-lwabiwo mali lofakelo lwayo kwaye yiyo loo nto kukho ezinye izisombululo ezingabizi kakhulu zokutsala umhlaba njengokudalwa kwemisa.
Umsebenzi ulula kuba kufuneka nyusa inyambalala phakathi kwe-20 kunye ne-30 cm ukuphakama, ushiya iindlela phakathi kobuninzi bamanzi ukuze ujikeleze apho. Emva koko kubekwa umaleko wegrabile oya kuthi uthintele iindlela ekugxobhozweni.
Kuyenzeka ukuba wenze umsebenzi ngaphandle koncedo lwangaphandle kwaye ngoncedo lwe-backhoe yokwenza iindlela.
