1. Izici kanye nezingozi zengqimba yesihlabathi nodaka
Uma kubholwa imigodi esihlabathini esicolekile noma enhlabathini enothuli, uma izinga lamanzi angaphansi komhlaba liphezulu, udaka kufanele lusetshenziswe ukwakha imigodi yokuvikela udonga. Lolu hlobo lwe-stratum kulula ukulugeza ngaphansi kwesenzo sokugeleza kwamanzi ngoba akukho ukunamathelana phakathi kwezinhlayiya. Ngenxa yokuthi umshini wokubhoboza ojikelezayo uthatha inhlabathi uyifake ngqo emgodini, inhlabathi ebholiwe iphinda isetshenziswe yibhakede lokubhoboza iye phansi. Ibhakede lokubhoboza lihamba odakeni, futhi isivinini sokugeleza kwamanzi ngaphandle kwebhakede lokubhoboza sikhulu, okulula ukubangela ukuguguleka kodonga lwembobo. Isihlabathi esigezwa udonga lwembobo sinciphisa kakhulu umphumela wokuvikela udonga wodaka lokuvikela udonga. Kungenzeka kakhulu ukuthi lubangele izinkinga ezifana nokuvikela intamo ngisho nokuwa kwembobo.
2. Uma indlela yokwakha yokubhoboza ngokujikeleza isebenzisa ukuvikelwa kodonga lodaka engqimbeni yokuqala yenhlabathi enhle yesihlabathi noma ye-silt, izinyathelo ezilandelayo kufanele zicatshangelwe:
(1) Yehlisa kahle ijubane lokwehlisa nokudonsa kwe-drill bit, yehlisa izinga lokugeleza kodaka phakathi kwebhakede lokubhoboza nodonga lwembobo, futhi yehlisa ukuguguleka.
(2) Khulisa ngokufanele i-Engela yamazinyo okubhoboza. Khulisa isikhala phakathi kodonga lwembobo nodonga oluseceleni lwebhakede lokubhoboza.
(3) Khulisa ngokufanele indawo yomgodi wamanzi ebhakedeni lokubhoboza, wehlise ingcindezi engemihle phezulu nangaphansi kwebhakede lokubhoboza ngesikhathi senqubo yokukhipha, bese wehlisa izinga lokugeleza kodaka emgodini omncane.
(4) Lungiselela ukuvikelwa kodonga lodaka olusezingeni eliphezulu, ulinganise ngesikhathi okuqukethwe kwesihlabathi sodaka olusemgodini. Thatha izinyathelo ezisebenzayo ngesikhathi lapho weqa indinganiso.
(5) Hlola ukuqina kwesembozo esingezansi sebhakede lokubhoboza ngemva kokuvala. Uma kutholakala ukuthi isikhala esibangelwa ukuphambuka sikhulu, kufanele silungiswe ngesikhathi ukuze kugwenywe ukuvuza kwesihlabathi.
