DTH Bits — RC (Reverse Circulation)

Ama-Robit DTH Bits wokuhlola ukujikeleza okuphambene (RC) aklanyelwe ukunemba nokwethembeka ezinhlelweni zokuhlola ze-geotechnical nezinsiza. Akhanyiswe ukuze kube lula ukuthola amasampula angcolile, lezi zinsiza ziqinisekisa ukusebenza kahle ezimweni ezahlukene zomhlaba, okwenza kube ithuluzi elibalulekile kubachwepheshe bezokubhoboza kanye nezokwakha. Indlela yokujikeleza okuphambene ithuthukisa ukusebenza kahle kokuhlanganiswa kwamampuli ngokuletha izigaxa phezulu nge-tube yangaphakathi, ngaleyo ndlela igcina ubuqotho bamasampula. Lezi zinsiza ze-DTH zakhiwe ngezinto ezisezingeni eliphezulu, zinikeza ukuhlala isikhathi eside nokumelana nokugqokwa ezimweni ezinzima. Ngezilinganiso ezahlukene nezimo ezitholakalayo, lezi zinsiza zingakhelwa ukuze zihlangabezane nezidingo ezithile zephrojekthi. Zinezakhiwo ezihlukile ezikhulisa ukuhamba komoya futhi zinciphisa ingozi yokungcola, kuqinisekisa ukuthi amasampula aqoqiwe akhombisa kahle izimo ezingaphansi komhlaba. Lezi zinsiza zihambisana nezinhlobo ezahlukene zemishini yokubhoboza, okuthuthukisa ukuhamba kwazo ezindaweni zomsebenzi. Ama-Robit DTH Bits asebenza kahle kakhulu ezinhlelweni ezifana nokuhlola izinsiza, ukuhlola kwemvelo, kanye nezifundo ze-geotechnical. Ikhono lazo lokukhiqiza amasampula angcolile libalulekile ukuze kube nokuhlaziywa okunembile nokwenza izinqumo ekwakhiweni kwephrojekthi. Noma usebenza emhlabathini othambile noma ezindaweni ezinzima zezitini, lezi zinsiza zinikeza ukusebenza okuqhubekayo nokwethembeka, ngaleyo ndlela zinciphisa isikhathi sokuphumula. Ngokuhlanganisa ubuchwepheshe obuphambili kanye nokukhiqizwa kwekhwalithi, ama-Robit DTH Bits ahlangabezana nezidingo zabaklami, abaphathi bamaphrojekthi, kanye nabathengi bemishini abafuna izinsiza ezithembekile ezithuthukisa ukusebenza kahle kokubhoboza. Ukusebenza kwazo okuqinisekisiwe ekutholeni amasampula okujikeleza okuphambene kuqinisa indima yazo njengengxenye ebalulekile kunoma iyiphi iphrojekthi yokwakha noma yokuhlola egxile ekutholeni idatha ethile engaphansi komhlaba.
