Ukurekhoda Idatha Yokubhola Okuphindwe Kabili

Emkhakheni wezokwakha izisekelo ezijulile nezobunjiniyela be-geotechnical, ukubaluleka kokubhaliswa kwedatha okunembile kokubhoboza okuphindwe kabili akufanele kudlulelwe. Lolu shintsho lwezobuchwepheshe lwenzelwe ukuthwebula nokurekhoda amapharamitha abalulekile okuhamba phambili ngesikhathi sokwenza amaphrojekthi wezisekelo ezijulile, ngaleyo ndlela kuqinisekiswe ukunemba nokusebenza kahle. Ngokusebenzisa ama-sensors avanayo kanye nezinhlelo zokuthola idatha, amathuluzi okubhaliswa kwedatha kokubhoboza okuphindwe kabili ahlinzeka ngempendulo yesikhathi sangempela kumametriki abalulekile afana ne-torque, izinga lokungena, kanye nesivinini sokujika. Le datha ibalulekile kubanjiniyela kanye nezinkampani ezidinga ukuqapha ukusebenza kokubhoboza nokulungisa amapharamitha ukuze kuthuthukiswe ukusebenza. Ukubhoboza okuphindwe kabili kuyindlela ekhethekile esetshenziswa ezimweni zomhlabathi ezinzima, lapho izindlela zokubhoboza ezijwayelekile zingase zingaphumelelanga. Lokhu kuhlanganisa ukusebenzisa uhlelo lwe-dual rotary, lapho i-casing yangaphandle ijikiswa ngokwehlukana ne-drill string yangaphakathi. Le ndlela ivumela ukususa kahle ukugwaza nokugcina ubukhulu be-borehole bungeniswe emhlabathini soft or unstable. Ukuhlanganiswa kobuchwepheshe bokubhaliswa kwedatha kuqinisekisa ukuthi wonke umkhankaso wokubhoboza ubhalwe kahle, kukhulisa ukuhlaziywa okuphelele kwezimo ze-borehole, ukusebenza kahle kokubhoboza, kanye nokusebenza kahle kwephrojekthi. Izicelo ezibalulekile zokubhaliswa kwedatha kokubhoboza okuphindwe kabili zihlanganisa imikhakha ehlukahlukene, okuhlanganisa ukujotshwa kwezisekelo, ukuthuthukiswa komhlabathi, kanye nokuhlola umhlabathi. Kumaphrojekthi wezisekelo ezijulile, kusiza ekutholeni ikhophi yokuphatha umthwalo komhlabathi kanye nokuhlonza izinkinga ezingase zivele ngaphambi kokuba zikhule. Ezikhaleni zokuthuthukiswa komhlabathi, ukubhaliswa okunembile kwamapharamitha okubhoboza kuqinisa ukufakwa kahle kwezindlela ezifana ne-grouting kanye nokuzinzisa umhlabathi. Ngaphezu kwalokho, ekuhloleni komhlaba, ukubhaliswa kwedatha kuhlinzeka ngemininingwane ebalulekile ngezimo ezingaphansi komhlaba, kusiza abanjiniyela ekwenzeni izinqumo ezinolwazi mayelana nokuthuthukiswa kwesizinda nezindlela zokwakha. Izincazelo ejwayelekile zamathuluzi okubhaliswa kwedatha kuleli qembu zifaka ukukwazi ukurekhoda idatha kwe-High-resolution, ukuhambisana nezinsiza zokubhoboza ezahlukene, kanye nesofthiwe yokuhlaziya idatha eqinile. Izici ezifana nokudluliswa kwedatha okujwayelekile, i-GPS ehlanganisiwe yokulandela izindawo, kanye nezinhlaka zokubika ezenzakalelayo zandisa ukusebenza kahle nokusebenza kahle kwamathuluzi. Uma ukhetha izinhlelo zokubhaliswa kwedatha zokubhoboza okuphindwe kabili, kubalulekile ukuhlela izinto ezifana ne-range yamapharamitha abhalwe, ukujula kokuhlanganiswa nezinhlelo zokubhoboza ezikhona, nehlangano yokwesekwa kobuchwepheshe enikezwa umkhiqizi. Ukutshalwa kwezimali ubuchwepheshe obuthembekile bokubhaliswa kwedatha kokubhoboza okuphindwe kabili akusizi kuphela ukuhlela inqubo yokubhoboza kepha futhi kunciphisa kakhulu ubungozi obuhlotshaniswa namaphrojekthi wezisekelo ezijulile. Ngokuhlinzeka ngedatha ebalulekile kuzo zonke izigaba zokubhoboza, lolu thuluzi lukehlukana nezinkampani kanye nabulteni ukuze kuthuthukiswe ukusebenza, kuthuthukiswe ukuphepha, futhi kuqinisekiswe ukuhambisana nezindinganiso zemboni. Emkhakheni lapho ukunemba nokwethembeka kubalulekile, izixazululo ezifanele zokubhaliswa kwedatha zibhalwe phansi ukuze kufezeke imiphumela empumelelweni emisebenzini yokwakha izisekelo ezijulile nezobunjiniyela be-geotechnical.
