Izikhumbuzo Zokubhoboza Eziqhulwini Zokuhamba

Izinsiza zokubhoboza ezixhunywe kumathuluzi wokumba zimelela isixazululo esihlukahlukene sokwenza ama-micropiling kanye nezicelo ezikhethekile zokuthuthukiswa komhlaba ezinsizeni zokwakha ezinzulu. Lezi zixhunywa zokubhoboza ezisebenza nge-hydraulic zifakwe ngqo kumathuluzi wokumba, okwenza kube lula ukuhamba ngokushesha nokubuyisela emuva ezindaweni zokwakha ngaphandle kokuhamba kwemishini ngezinga elincane. Lezi zithuluzi zinikeza amandla aqondile nokubhoboza okukhuphukayo okuyisisekelo sokufaka ama-micropile, okuyizinto ezinzulu ezinomthamo omncane ophakathi kuka-150 no-300 mm. Ngokusebenzisa imishini yokumba esivele ikhona, abakhiqizi banciphisa ukutshalwa kwemali ngenkathi behlisa umkhawulo wokushintsha phakathi kwemisebenzi yokubhoboza kanye nemisebenzi ejwayelekile yokusebenza komhlaba ezinhlelweni zokwakha eziyinkimbinkimbi. Izithuluzi zokubhoboza ezixhunywe kumathuluzi wokumba zenza kahle ezimeni ezinzima ze-geotechnical lapho imishini emikhulu yokubhoboza ingafinyeleli ezindaweni ezivinjelwe. Lezi zinhlelo zikwazi ukudlula emathafeni anzima, edakayo, nakwimingcele yokusekela engcono ukuze kuqaliswe ama-micropiles edlulisa izithwalo kumathafa angaphezu, asindayo kakhulu. Izindlela zokubhoboza ziqonda ngezimo ezahlukene zomhlaba ezihlanganisa i-clay, isand, igalufu, amatshe amancane, kanye nezindawo eziphukile, okwenza zibe yizinsiza ezibalulekile kumafekthri emadolobha, ukulungisa izakhiwo ezikhona, nokuqinisa umsebenzi wokwakha. Ukumiswa kwamathuluzi kuvumela abaklami ukuthi bagcine ukuvumelanisa okuqondile nokuphakama ngesikhathi beqedela ubude bokubhoboza obuvame ukuba phakathi kuka-15 no-40 amamitha, kuye ngemfaniswano yomhlaba nezidingo zokuthwala. Abakhiqizi bavame ukusebenzisa lezi zixhunywa ukuze balondoloze umhlaba ezindaweni ezithintekile ukusondela, ukukhipha, noma imisebenzi ye-seismic lapho ukuqina okukhethekile kwezindawo ezibuthakathaka kuvimbela ukuhamba okungafani nezingozi zesakhiwo. Ukuhamba kokusebenza kwezithuluzi zokubhoboza ezikhona kumathuluzi wokumba kuqhubekisela phambili kumasu akhethekile wokubhoboza ama-micropile ahlanganisa ukufakwa kwamathuluzi kumathafa, amasistimu agcwele amanzi anokuphakanyiswa, kanye nezinto eziphakanyisiwe zokwandisa umthamo wokuthwala. Abasebenzi baphatha ama-sequence wokubhoboza ngokuqondile, begcina ukuhamba okuqhubekayo nokukhipha okuyisistimu okukhuhla izinsoli futhi kuqedele izindonga zebholo ngesikhathi sokuqhubeka. Izinhlelo zamandla ze-hydraulic ezihlanganisiwe zisingatha i-torque yokubhoboza nokuqinisa, ziqonda ukuphuka komhlaba nokuvinjelwa okungazelelwe, kanti zivikela abasebenzi nemishini. Umkhiqizo wesikhala uthola izinzuzo ezivela ekuhamba ngokushesha, isikhathi sokwakhiwa esincane, kanye nokuhlinzeka kwamandla okuhlanganisiweyo okuvela kumathuluzi wokumba, okwenza abakhiqizi bakwazi ukuqeda ngokuphumelelayo izinhlelo eziyinkimbinkimbi zokubhoboza ama-micropile ezindaweni ezincanyana. Izicelo zibandakanya ukuhweba kwezokwakha kuhlanganisa ukwakhiwa kwamathafa okukhulisa amabhuloho, izikhalazo, kanye nokugcinwa kwezakhiwo zomlando, khona lapho izimo zomhlaba zidinga izixazululo zokwakha ezinzulu. Ukuhlolwa kwe-geological kanye nemikhankaso yokuhlola umhlaba kusebenzisa lezi zinhlelo ukuze kube nokubhoboza okuqondile nokulanda amasampula ezindaweni eziyinkimbinkimbi. Ukuvumelana kokuhlanganiswa nezithuluzi zokumba ezijwayelekile eziphakathi kuka-15 no-35 amaton, kulethela abakhiqizi ukwakha okukhaliphile eziphathweni ezahlukene, kuhambisana nemodeli yebhizinisi lapho ukusabalalisa kwemishini kunciphisa izindleko zokusebenza ngenkathi kuqinisekisa amandla e-geotechnical akhethekile abalulekile ezinsebeni zokwakha ezinzima kwezokwakha zanamuhla.
