Banikela ngezinzuzo eziningi ngaphezu kwezindlela zesisekelo zendabuko, zibenze ukuba babe ukukhetha okuthandwayo kuwo womabili amaphrojekthi wokuhlala nawokuhweba. Ngakho-ke, kusebenza kanjani izikulufu zomhlaba? Izikulufo zomhlabathi ziqukethe i-Shaft yensimbi enamapuleti angenamoya anamathele kuwo. Lawa mapuleti afana nesikulufa esikhulu futhi aklanyelwe ukungena emhlabathini kalula. Izikulufo zidonswa emhlabathini zisebenzisa imishini ekhethekile, efana nabashayeli be-hydraulic noma imishini yokuphathwa ngesandla. Njengoba zikhohliswa emhlabathini, amapuleti endiza adala ukubamba okuqinile emhlabathini, anikeze ukuqina kanye nokuthwala umthwalo. Enye yezinzuzo ezisemqoka zezikulufo zomhlaba ukuzishintsha kwazo. Zingafakwa ezinhlotsheni ezahlukahlukene zenhlabathi, kufaka phakathi ubumba, isihlabathi, kanye nendawo enamadwala. Lokhu kuguquguquka kuvumela ukufakwa okulula ezindaweni ezahlukahlukene zezwe, okwenza izikulufa ze-Ground Screws inketho esebenzayo yamaphrojekthi ezindaweni ezahlukahlukene. Izikulufu zomhlaba zinikeza izinzuzo eziningana ngaphezu kwezindlela zesisekelo zendabuko. Okokuqala, badinga ukumbiwa okuncane, ukunciphisa isikhathi nomzamo odingekayo wokwakha.
