I-CFA Augers

Ama-CFA augers, noma ama-Continuous Flight Augers, ayizinsiza eziyisisekelo ezisetshenziswa ekwakheni izisekelo ezijulile kanye nezezimali ze-geotechnical, ikakhulukazi ekufakweni kwezinsika ze-concrete ngaphandle kwesidingo sokufaka i-casing. La ma-augers akhelwe ukuhamba phansi komhlabathi ngenkathi ethutha umhlabathi ohlwanyelwe phezulu, okuvumela ukusebenza kahle nokuphumelelayo kokuhamba. Umdlalo ohlukile wama-CFA augers ubonisa i-spiral ehlala iqhubeka, evumela ukuhambisana okuqhubekayo kokukhipha umhlabathi, okwenza kube ukuhlangana kahle kokukhulisa ama-boreholes ezimweni ezahlukene zomhlabathi. Ngokusebenza, ama-CFA augers asebenza ngokujikiswa emhlabathini besebenzisa i-drilling rig ekhethekile. Njengoba i-augere ihlaba umhlaba, ukuhamba okuqhubekayo kuqhubela phezulu ukutholwa, kukhulula kahle isikhala. Uma ubude obufunwa bufinyelelwa, i-concrete iphonswa ngombhobho ongenalutho we-augere, igcwalisa i-borehole ngenkathi i-augere ikhishwa kancane. Le ndlela ayigcini ngokunciphisa ukuphazamiseka komhlabathi kodwa iqinisekisa ukuthi i-borehole ihlala iqinile ngesikhathi sokufakwa kwe-concrete. Ukuhlanganiswa kokuhamba kanye nokufakwa kwe-concrete ngesikhathi esisodwa kunciphisa kakhulu isikhathi nomsebenzi ophikweni lwezikhungo ezijulile. Izinhlelo ezibalulekile zama-CFA augers zifaka ukufakwa kwezinsika zezitimela, izakhiwo, nezinye izakhiwo ezidinga izisekelo eziqinile. Zisebenza kahle kakhulu ezindaweni zasemadolobheni lapho kunezithiyo zomsindo nokugqugquzela, njengoba indlela ye-CFA ikhiqiza amazinga aphansi kokubili uma kuqhathaniswa nezinsika ezishaywa ngendabuko. Ngaphezu kwalokho, ama-CFA augers afanelekela izinhlobo ezihlukene zomhlabathi, kuhlanganise nezikhala ezithambile, ama-silt, futhi nakwamanye ama-granular soils, okwenza kube amathuluzi ahlakaniphile esikhwandleni se-geotechnical engineer. Lapho ukhetha ama-CFA augers, kufanele kubhekwane nezincazelo eziningana ukuze kuqinisekiswe ukusebenza kahle. Lokhu kufaka phakathi umthamo we-augere, ovame ukuhamba phakathi kwe-300 mm kuya ngaphezulu kwe-1000 mm, kanye nobude, obungahluka ngokuya ngezidingo zom project. Izinto nezakhiwo zamaflight e-augere nazo zidlala indima ebalulekile ekusebenzeni kwazo nasekugcineni. Kubalulekile ukukhetha i-augere engabhekana nezimo zomhlabathi ezithile kanye nobude bezinhlelo. Ubuye bube yinto ebalulekile ukuvumelana nezinsiza ezihlukahlukene ze-drilling rigs, njengoba cha zonke izinsiza ziqinisekile ukuze zisebenze nezinhlobo zonke ze-CFA auger. Ngokufingqa, ama-CFA augers ayingxenye eyisisekelo yokwakhiwa kwezisekelo ezijulile kanye nezezimali ze-geotechnical, anika isixazululo esithembekile nephephile sokufakwa kwezinsika. Ikhono lawo lokuhamba nokufaka i-concrete emsebenzini owodwa lenza kube ukukhethwa okuthandwayo kwabanye abaqashi. Ngokuqonda ukusebenza kwawo, izicelo, nezincazelo ezibalulekile, amabhizinisi angakwenza izinqumo ezinembile lapho kukhethwa ama-CFA augers afanele emaphrojeni awo, kuqinisekiswa imiphumela eyimpumelelo endaweni ethuthukayo yokwakhiwa kwezisekelo ezijulile.
