Iziqhumiso ze-CFA ezineziqhumiso ezimbili

Emkhakheni wokwakhiwa kweziqalo ezijulile kanye nezinjini zomhlaba, ama-Double-Start CFA Augers adlala indima ebalulekile ekuthuthukiseni izindlela zokwakhiwa kwe-CFA (Continuous Flight Auger) piling. Lezi zinsiza ezikhethekile ziqondiswe ekudaleni izikhukhula ezingqondweni ezinzima, zivumela ukufakwa kahle kwezimbambo ezisekelayo ezakhiweni ezihlukahlukene, zisuka emathinini kuya ezakhiweni eziphakeme. Ngokuxhumana kwezikhala ezimbili, ama-Double-Start CFA Augers athuthukisa inqubo yokumba, evumela ukusebenza kokuhlasela okubhalelekile kanye nesivinini somsebenzi uma kuqhathaniswa nezinye izinsiza eziyibhakabhaka eziphakeme. Ukuhleleka kwezingxenye zamama-Double-Start CFA Augers kusekelwe ekwakhiweni kwazo okukhethekile, okuhlanganisa ukwakheka kokuphakanyiswa okuqhubekayo okwenza kube nokubumba okuqhubekayo, ngenkathi kusetshenziswa okukhukhulayo kwezakhiweni eziphakamisa. Lokhu kuklanywa kwehlisa kakhulu amathuba okuphuka komhlaba ngesikhathi sokukhazimula, kuxazulula izinselelo ezivamile ezibhekene nomsebenzi wezobuchwepheshe, njengezimo zomhlaba ezivuthayo noma ezingezi kahle. Njengoba i-auger ingena ngaphezulu komhlaba, i-concrete noma i-grout ingafakwa ngasikhathi sinye, kuqinisekisa ukuthi isikhukhula sisaqhubeka sikhona futhi sigcwele, okuyinto ebaluleke kakhulu ekwakheni izimbambo eziqinile ezikhipha umthwalo. Izicelo zama-Double-Start CFA Augers zifaka izikhala ezahlukene zomkhakha wokwakha, ikakhulukazi ezindaweni ezisemadolobheni lapho izixazululo zeziqalo ezijulile zihlala zidingeka ngenxa yokuncishiswa kwendawo kanye nezimo zomhlaba ezinzima. Lezi zinsiza zisetshenziswa kabanzi ekwakheni iziqalo ezindlini zokuhweba, ezakhiweni zezindlu, kanye nezinhlelo zokwakha, lapho izinhlelo eziqinile zokuxhasa ziphumelela kakhulu. Ukusebenza kwazo nokukwazi ukuzivumelanisa nezimo zomhlaba ezihlukahlukene kwenza kube yinto ewusizo ezinhlelweni zokuthuthukiswa komhlaba, njengezinhlelo zokugcinwa komhlaba nokwenziwa kabusha. Izincazelo ezivamile zama-Double-Start CFA Augers zifaka ububanzi obuphakathi kuka-300 mm kuya ku-1200 mm, ubude obungadlula amamitha angama-20, kanye nekhono lokuphatha amazinga e-torque ahlukahlukene kuye ngesimo somhlaba nezidingo zokuhlasela. Uma kukhethwa i-Double-Start CFA Auger efanelekile, izimfuneko eziningi kufanele zicatshangelwe. Lokhu kuhlanganisa izici zomhlaba ezithile endaweni yephrojekthi, amandla alindelekile wezimbambo, kanye namakhono okusebenza kwezinsizakalo zokuhlasela. Kubalulekile futhi ukuhlola ukufaniswa kwe-auger nezinsiza zokuhlasela, kuqinisekisa ukuthi i-torque nomjikelezo kuhambisana nezincazelo ze-auger ukuze kuqinisekiswe ukusebenza kahle. Ngokubamba kwayo, ukusebenza kahle kanye nezikhathi ezithembekile zama-Double-Start CFA Augers kwenza kube ukukhetha okuthandwayo kwabathekniki nabaklami abakhangayo emisebenzini yeziqalo ezijulile nezobuchwepheshe. Ngokwazi ukusebenza kwabo, izicelo, kanye nezimfuneko zokukhetha, ochwepheshe embonini bangakwazi ukwenza izinqumo ezihlakaniphile ezithuthukisa imiphumela yephrojekthi futhi ziqinisekise ukuphepha nokusebenza kahle kwezindawo ezakhiwayo. Njenge-ekhaya lezinsiza ezingcono, sicebisa uhla lwezinketho zokuthenga noma zokuthola ama-Double-Start CFA Augers, sithuthukisa ibhizinisi ukuba lihlangabezane nezidingo zabo zephrojekthi ngokuzethemba nangokwethembeka.
