Izinsiza Ezikhethekile ze-CFA

Izinsiza ezikhethekile ze-CFA zimele amathuluzi abalulekile nezithako ezithembisa amandla ezinhlelo zokushaya i-auger eziphakathi kokwakhiwa kwemigqa e deep foundation kanye nezicelo ze-geotechnical. Lezi zinsiza ezikhethekile zandisa ukuhlela nokusebenza kwe-CFA rigs ngesikhathi sokufaka izimbobo eziyinkimbinkimbi, ukuthuthukiswa komhlaba, kanye nemisebenzi yokuzinza komhlaba ezimweni zejogazi ezahlukene. Noma kunjalo ekubhekaneni nezithombe zomhlaba ezinzima, ukuthuthukisa amandla okuphawu, noma ukusebenzisa izindlela zokudrill ezikhethekile, izinsiza ezikhethekile ze-CFA zivumela abaqashi ukuba bahlale belungile ezixazululweni zabo zokwakha izisekelo nangokwenza umsebenzi ophumelelayo emakhaya. Uhlu lwezithako ezikhethekile olukhona luvumela abasebenzi ukuba benze ngezindlela zabo ezivamile ze-auger ukuze zihambisane nezidingo zomsebenzi ezingehilelanga izinhlelo zokushaya eziyinzima ngokwakho, okwenza kube yisixazululo esiphumelelayo sezindleko kwabathengi abaphatha izinkinga eziningi zokwakha izisekelo. Ekukhathaleleni izisekelo, ukuhamba kwe-CFA kuvunywa kakhulu ngokusebenza kahle kwawo ekufakeni izimbobo zokuhamba ezinciphisa ukuphazamiseka komhlaba ngenkathi kuthuthukisa amandla aphezulu okusindisa. Amathuluzi akhethekile ezinhlelo ze-CFA ahlanganisa ama-casing oscillators, ama-casing wesikhashana anemihlahlandlela ethile, ama-kelly bars aneziro ezithuthukisiwe, kanye nezindawo zokuxhuma kumathuluzi okuthuthukisa umhlaba njengezinhlelo zokugrouta kanye nezinsiza zokudlidliza. Lawa mathuluzi avumela abasebenzi ukuthi benze i-CFA drilling ezimakethe eziphakathi kwe-clays ezinzima kanye nezinsizakalo ze-granular nakuba kunezindlela ezihlanganisiwe lapho izindlela zendabuko zingase zibe nzima. Ikhono lokwethula izindlela zokuthuthukisa umhlaba ezilawulwayo ngesikhathi sokufaka izimbobo kwenza izinsiza ezikhethekile ze-CFA zibe nezindleko kakhulu kumaphrojekthi adinga ukuthuthukiswa kokucindezela kwangaphakathi, zithuthukise amandla wokuphatha, noma zisebenze ngokuhlanganyela. Izicelo ziya emiphakathini yasemadolobheni lapho ukungqubuzana nokukhala kuncane kubalulekile, kanye nasezindaweni zokwakha ezisemva kwemanzini futhi ezikude lapho ukufaneleka kokuthuthuka nezimo zokusebenza kubalulekile. Ukusebenza kahle kwezinsiza ezikhethekile ze-CFA kusekelwe ekukhetheni izithako ezihambisana nezimo zomhlaba, izinhlelo zamanzi angaphansi, nezidingo zokwakha. Abakhiqizi abathola izimfuno ezihambisana nezinhlelo ezimaphakathi ze-auger bathola inzuzo yokufinyelela kumathuluzi okudrill akhethekile athuthukisa ukufaka ngokusebenzisa izindawo ezinzima, izithombe zomhlaba ezingafani, kanye nezimo ezisezingeni eliphezulu noma eziphikisanayo. Izinsiza zanamuhla ze-CFA ezikhethekile zifaka izinhlelo zokwakha ezinemigomo yokuhambisana ezinhlelweni ezihlukahlukene ze-rig ngenkathi zigcina ukusebenza kahle kokudrill nokuphepha ngesikhathi sokufaka izimbobo. Ochwepheshe bokuthuthukisa umhlaba babaluleka kakhulu kulawa mathuluzi ngenxa yekhono lawo lokuhlanganisa imisebenzi yesibili efana nokufaka izinto zomgogodla eziphansi, ukufaka ukuphakela, noma ukuvibro-compaction ngaphakathi komjikelezo owodwa. Uma ekhethwe kahle futhi ukusebenza kahle, izinsiza ezikhethekile ze-CFA zithuthukisa kakhulu imiphumela yephrojekthi ngokunciphisa isikhathi sokwakha sonke, kunciphisa umthelela kwendawo, futhi kuvumela abaqashi ukuba bafeze izidingo ezicatshangelwe kahle kumaphrojekthi ezisekelo ezezakhiwo, ezentengiso, ezimboni, kanye nezabasebenza kahle kwezomnotho.
