I-Continuous Flight Auger CFA

I-Continuous Flight Auger (CFA) piling imele indlela ekhethekile yokwakha izisekelo ezijulile eyihlanganisa ubuchwepheshe bokudrillisa obujikayo nokufakwa kwekhonkrithi ngesikhathi esifanayo, okuhoxisa isidingo sokusebenzisa amacala wesikhashana noma izinhlelo zokuxhaswa ze-bentonite slurry. Le ndlela yokuphuma kwepali ibandakanya ukusebenzisa i-augere enomgogodla oholwayo onezindiza ezijikayo ezijikeleza ngokuqhubekayo emhlabeni kuya depth efanele ngenkathi ikhonkrithi iphushwa nge-shaft yangaphakathi ngaphansi kwengcindezi. I-augere ibhajwe kancane ngesikhathi ikhonkrithi entsha igcwalisa ibhuloho, idala i-pali eqinile yeziqinisekiso zekhonkrithi enezakhiwo ezinhle zokuncintisana kweshawti. I-CFA piling ikakhulukazi isebenza kahle emithonjeni ethambile, izinkomba ezibambekayo, ama-silts, kanye ne-sands ephakathi nendawo ukuya ezincane lapho izindlela zomlenze ezivulekile ezivamile zizo geshe izinselelo zokuzinza noma ukulahleka komhlaba okwengeziwe. Le ndlela ivumela abaqashwa ukuthi bafinyelele amazinga wokufakwa kwepali ngokushesha ngenkathi begcina izinga eliphusile le-pali phakathi kwamabhuloho amaningi kumaphrojekthi ezisekelo ayinkimbinkimbi. Ukusebenza kwezezimali kwe-CFA piling kusekelwe kokuhlanganiswa kwezinsiza ezichwepheshe kanye nokuhlola izimo zomhlaba. Ukuhlolwa komhlaba okukhuphukile kanye nezibalo ze-geotechnical kuyimfuneko ebalulekile ukuze kutholakale usayizi olinganiselwe we-augere, izimfanelo zekhonkrithi, kanye nezinga lokufakwa. Le nqubo idinga ama-rigs akhethekile e-CFA adlalisa ama-units akhulu wokunikezela, izinhlelo ze-hydraulic ezikwazi ukuphatha ukucindezela okuphezulu, kanye nezinhlelo zokuhanjiswa kwekhonkrithi ezinezinhlelo zokulawulwa kwengcindezi eziqinile. Izimo zomhlaba ezifana nezinga lamanzi, ukwakheka kwezinto, ubuncane obuphakathi, kanye namandla okuphatha kuthinta ngqo ijubane lokudrillisa kanye nokusebenza kokugcina kwepali. I-CFA piling ikhethekile emiphakathini yasemadolobheni lapho ukulawula ukuvusa kubalulekile, njengoba le ndlela idala umsindo omncane nezikhukhula uma kuqhathaniswa nezinsiza zokushaya noma zokuvusa ama-pile. Ubulukhuni bokuhlanza umhlaba obungakhiyeki budidiyela nokufakwa kwekhonkrithi okulawulwayo kuvumela ukufakwa phakathi kwezinto ezizimele ngenkathi kugcinwa ukuxhaswa okujwayelekile kwezakhiwo ezilungile nezikhiphiwe eziphansi. Izicelo ze-CFA piling zihlanganisa amaphrojekthi okwakha izindlu, ezokuhweba, ezimboni, kanye nezokwakha ukuphila ezidinga izixazululo eziqinisekile zezisekelo ezijulile. Izindawo zokwakha amabhuloho, izakhiwo eziphakeme, izakhiwo zezimoto, kanye nezinhlelo zokuthuthukiswa komhlaba zihlala zifuna ama-pali e-CFA ngenxa yokuphenduka kwawo nokusebenza ngaphansi kwezimo ezahlukahlukene zokuhlola. Le ndlela iyahambisana nezilinganiso ezahlukene zamapali kumaphrojekthi ambalwa ngaphandle kokudinga ukuphindisela izinsiza, yenze kube kuhle ngokwezimali ezisekelweni ezinobungozi bokuhluka kokuhlala. Ama-CFA piles akhiqiza amandla aphakeme wokucindezela kanye nokumelana nomthwalo ophakathi nendawo ngokuthuthukiswa kwezindawo zokuncintisana kweshawti emithonjeni ebambekayo kanye nokufakwa okwanele kumazwe anamandla. Izinsiza zanamuhla nezinhlelo zokubhekwa ezihlanganiswe nezinsiza ze-CFA ziqinisekisa ukuqinisekiswa kwesimo sekhonkrithi, ukuphathwa kokwehla, nezimo zokufakwa, okuvumela ukuqinisekiswa kokusebenza okuphelele nezinguquko ezilungisayo ngesikhathi sokwakha. Ukuhlanganiswa kokufakwa kwemfundo, ukuzivumelanisa nezimo zomhlaba, umphumela wombuso ophansi, nokusebenza kwezakhiwo okwakhiwe okulungile kuwenza i-CFA piling kube ubuchwepheshe obufiselekayo bezisekelo ezijulile zokwakha kwensiza ye-geotechnical kumkhakha wokwakha izisekelo.
