Iphansi lolwandle

Emkhakheni wezokwakha izisekelo ezijulile kanye ne-geo-technical engineering, imishini yokuhlola ulwandle ibaluleke kakhulu ekuqinisekiseni ukuzinza nokuthembeka kwezakhiwo ezakhiwe ezindaweni zasolwandle. Le mishini eyakhelwe ngezifiso iklanyelwe ukuqhuba Ukuhlolwa Kwe-Cone Penetration (CPT) ngqo ebhizini, inika idatha ebalulekile mayelana nezici zomhlabathi kanye ne-stratigraphy ezokwazi ukunikeza izinqumo zokwakha. Ukusebenza kwe-CPT yebhizini kubandakanya ukufaka i-cone penetrometer enesicucu sesiteshi esiqhunyiswa ebhizini. Le nqubo ikala ukumelana nokungena, inikeza idatha ngesikhathi sangempela yokuziphatha nezici zomhlabathi, njengezinga lomhlabathi, ubukhulu, namandla. I-CPT yebhizini ibalulekile ezinhlelweni eziningi, ikakhulukazi ekwakhiweni nasekufakeni izisekelo ezijulile zezinsika zasolwandle, okuhlanganisa ama-wind turbines, amapulatifomu kawoyela, kanye nezikhumulo zasolwandle. Ngokuhlola izici ze-geotechnical zebhizini, ososayensi bangakwazi ukuhlole kahle amandla okuthwala umthwalo nezici zokuhamba kwephezulu, okuyizinto ezibalulekile ekuqinisekiseni ukuphepha nokusebenza kwezinto ezibhekiswe ezimweni zasolwandle eziguqukayo. Ngaphezu kwalokho, ukuhlolwa kwezinhlanzi kusiza ezinhlelweni zokuthuthukisa umhlaba, lapho ukuqonda izici zomhlabathi kubalulekile ekwenzeni izindlela zokwenziwa ukuthi zisebenze kahle. Izincazelo ezijwayelekile zemishini ye-CPT yebhizini zifaka phakathi i-cone enobubanzi obungama-35.7 mm kanye nobude obungamakholi angama-1, nakuba usayizi ungashintsha ngokuya ngezidingo zephrojekthi. Le mishini ivame ukuhlinzekwa ngezinhlelo zedatha electronic acquisition ukuze kube lula ukulandelela nokuhlaziya ngesikhathi sangempela. Izinga lokungena kanye namakhono obude angahluka kakhulu, nonke amasistimu anekhono lokufinyelela ubude obungama-30 meters noma ngaphezulu, kuye ngezimo zomhlabathi kanye nokwakhiwa kwemishini. Uma ukhetha imishini ye-CPT yebhizini, izimo eziningana kufanele zicatshangelwe ukuze kuqinisekiswe ukusebenza okuphezulu nokunembile. Lokhu kufaka phakathi uhlobo lomhlabathi olulindelekile endaweni yephrojekthi, ubude bokungena obudingekayo, kanye nedatha ethile edingekayo ukuze kuhlolwe kahle i-geotechnical. Ngaphezu kwalokho, ukukhethwa kwemishini kungase kuxhomeke ezintweni zemvelo ezifana nokuphakama kwamanzi, izimo zokukhuphuka, nezimo zezulu, ezingakwazi ukuthonya ukufakwa nokusebenza kwemishini. Kubalulekile futhi ukuhlola ukuhambisana kwemishini nezinye amathuluzi nezindlela ze-geotechnical ezisetshenziswayo kuphrojekthi ukuze kuqinisekiswe ukuhlolwa okunembile kwezimo zebhizini. Ekuphetheni, imishini ye-bhizini iyingxenye ebalulekile kumathuluzi ososayensi be-geotechnical kanye nabakhi abahilelekile emsebenzini wezisekelo ezijulile ezindaweni zasolwandle. Ikhono layo lokuhlinzeka ngedatha ebalulekile ngezici zomhlabathi likhulisa izinqumo ezinolwazi futhi lisekela ukwakhiwa kwezisekelo eziphephile, ezisebenzayo kwi-odolo yokusebenza kwasolwandle. Njengoba kudingeka ukuhlolwa kwezinye izimbobo ngokuya phambili, ukutshalwa kwezimali kwemishini ye-CPT ye-bhizini ephezulu kubalulekile ukuze kufezwe imiphumela ephumelelayo emisebenzini enzima yokwakha ngaphansi kwamanzi.
