Amabhithi e-CFA Pilot

Amathuluzi e-CFA pilot ayizithako ezibalulekile ezikhethekile eziqinisekisa inqubo yokubhoboza nge-auger yokuhamba okuqhubekayo ekwakheni izisekelo ezijulile. Lezi zibhengezo ezakhiwe kahle zisetshenziswa ekusungulweni kwezimbobo, zisebenza ukuthinta izendlalelo zomhlaba eziphezulu futhi zakhe ivulekile yokuqala ye-shaft ehola yonke i-auger assembly phansi. Emisebenzini yokubhoboza nge-auger yokuhamba okuqhubekayo, ama-pilot bits abhekelela ukuvula umhlaba nokusungula ukuhlelwa kwezakhiwo ngaphambi kokuba ama-auger flights agcwale ubuqotho. Uk dizayini kanye nezincazelo zalezi bits ziba nomthelela oqondile ekuphumeleleni kokubhoboza, ikhwalithi yemigudu, kanye nesikhathi sokuphothulwa kwephrojekthi. Ama-pilot bits kufanele akwazi ukuhambisana nezimo zomhlaba ezihlukahlukene ezitholakala ezindaweni ezincane, kusukela kumathuli omhlabathi owamukelayo nendawo encane kuya kumsand и uphiko olujulile, okwenza ukwakhiwa kwabo nezimo zokugijima zibe sezingeni eliphezulu ukuze kuqinisekiswe impumelelo yokubhoboza. Ukusetshenziswa kwama-CFA pilot bits kuqhubeka kulo lonke uchwepheshe bokwakha izisekelo, kufaka phakathi ukwakhiwa kwezimbobo ezijulile, ama-piles aborwe, kanye nezisekelo ezijulile zezakhiwo eziphakeme, izigcawu, amaphrojekthi ezokuthutha, kanye nezikhungo zezimboni. Abaphakeli bezobunjiniyela be-geotechnical basebenzisa ama-pilot bits ukuze basungule izimbobo ezinzima lapho kuthuthukiswa umhlaba noma zidingeka izindlela zokubhoboza ezikhethekile. Lezi bits zibalulekile ezindaweni zasemadolobheni lapho ukubhoboza okuqondile nokunganciki kokushaya ukuphuka kuyadingeka, kanye nasezindaweni ezinokufinyelela okukhawulelwe lapho amathuluzi wokubhoboza aconiwe kanye nezithako ezisebenzayo zikhombisa ngqo ezinhlelweni zephrojekthi. Ikhono le-pilot bit lokungena ngokushesha ezindaweni zomhlabathi eziphezulu kukhuthaza izinhlelo zokubhoboza ezisheshayo, kunciphisa isikhathi sokuphumula kwemishini futhi kuthuthukise umkhiqizo wabasebenzi kuma-oda wokwakha acushiwe. Ama-pilot bits e-CFA kufanele asebenze ngokuthembekile ezimweni ezahlukene zomhlabathi nezimo zomhlaba, kusukela kumagcobo aphezulu angenamandla kuya emhlabathini abhulwa ngemigqa efanele. Ababholi bakhetha izincazelo zama-pilot bits ngokuya ngemininingwane yokuhlola engaphansi komhlaba kanye nokulindelwa kokumelana nokubhoboza, balinganisa ezimeni ezifana nombala wesihlabathi, ukujula komswakama, nokuba khona kwezindlovu noma izendlalelo ezivimbela. Ama-bits kufanele agcine ukunembile kokuma ngesikhathi sokuqala ukuze kuqinisekiswe ukuthi ama-auger flights alandelayo evola phezulu futhi ablebhuze, kuvinjelekile ukunyakaza okungase kwezomzimba ukwehlisa i-shaft. Ukubhoboza nge-auger yokuhamba okuqhubekayo ngezitholelo ezikhethiwe ze-pilot bits kukhuthaza ubuhlobo obuhle bemigudu nokhwalithi yezindonga uma kuqhathaniswa nezindlela ezijwayelekile ze-rotary, ikakhulukazi ezimweni zokungazinzile zomhlaba lapho ubuhlobo bemigudu phakathi kokubhoboza bukhala. Ukutholwa kwama-CFA pilot bits afanele kubonisa ukutshalwa kwemali okukhulu empumelelweni yomsebenzi wokubhoboza. Abahlinzeki bemishini abaqondene nobuchwepheshe bokubhoboza be-auger yokuhamba okuqhubekayo banikeza izimo ezihlukene zama-pilot bits ezithuthukisiwe kwezimo zomhlaba ezithile nezindawo zokubhoboza, kusukela kuma-pilot bits okwakhiwa ngezisekelo eziphakeme ukuya kwama-variations okuphuthumayo okubuyela kokubhoboza izimbobo ezijulile ezidlula kumamitha angama-40. Ukugcina kahle ama-pilot bits, okubandakanya ukulungisa imiphetho kanye nezikhathi ezikulungile zokushintshwa, kuqinisekisa ukusebenza okuvamile kokubhoboza futhi kwandisa ubude bokuphila kweziqeshana. Abapheki bokwakha abaphethe izisekelo belindele ukuthi lezi bits ezikhethekile zisebenze kahle ekwandiseni ukusetshenziswa kwe-auger rig, ezifinyelela ezindleleni ezivunyelwene zokuqhuba, futhi zigcine ukunemba kobuchwepheshe okudingekayo ngezinga lokwakha lemiphakathi yanamuhla.
