Izinsiza Zokuqhafaza ZamaScrew Piles

Izinsiza ezihlanganisiwe ze-excavator eziklanyelwe ukufakwa kweziqongo ezifakwe ngemikhonto ziwumthombo obalulekile ezintweni zanamuhla zobunjiniyela bezisekelo zeziqongo zepulasitiki, zivumela abaqashi ukuthi bathole izixazululo ezisebenza kahle, ezibiza kancane ekuqiniseni okujulile ezindaweni ezihlukahlukene zomhlabathi nezimo zomhlaba. Lezi zinsiza eziqondile ziguqula ama-excavators ajwayelekile abe imishini ehlosiwe yokufaka ama-screw piles, sinikeza umjikelezo wokudonsela kanye neqhinga elilawulwayo lomoya elidingekayo ukuze kuthuthwe ama-screw piles kube izifunda zokuthwala ezinamandla. Indlela yokufaka ebhodini ye-excavator ikhipha isidingo sama-rotary drilling rigs amakhulu ezinhlelweni eziningi, okwenza ukufakwa kwesikhumbuzo sibe lula ezindaweni ezinomkhawulo wesikhala, ezindaweni ezithintwa kwezokwemvelo, nasezinhlelweni lapho izindleko zokuhamba nemfuneko yokuhlela indawo zifuna izinketho zemishini ezilula. Izinhlelo zokuxhuma ngokuvamile zifaka imishini yokuhamba ye-hydraulic, ama-load cells okusebenzisa isikhathi sangempela, kanye nezikhala ze-leader eziphethwe kahle eziqinisekisa ukuhambisana okucacile kokujula noma okuphumelelayo ngesikhathi sokufakwa, ukuqinisekisa ukuvama okwanele komhlaba kanye nokusebenza okuhle kweziqongo. Inqubo yokufaka ihilela ukujikeleza kwe-screw pile ngenhloso elawulwayo ngenkathi kusebenze uhlelo lok Pressure olulawulwayo, kuvumela ama-helical flights ukuba azibandakanye ngenhloso futhi akhulise umhlabathi ozungezile njengoba i-pile iqhuba ku-deph yomklamo. Le ndlela yokufaka ibonakala ikhululekile ezindaweni ezihlanganiswe kahle, izinsiza ezithambile, izinhlelo ze-silt-clay, kanye nezinhlaka ze-rock ezishintshelwe lapho izindlela ze-impact driving noma ze-vibratory zingase zibe nezinkinga. Idizayini ye-helical thread ye-screw pile isebenza njengomakhenikhali wokusika nokuhlala kanyekanye, ikhipha umhlabathi omncane ngesikhathi sokufakwa futhi inciphise ukuphazamiseka okuxhumene ne-vibration—ukuze kube nenzuzo enkulu ezindaweni ezinamakhulu, ezincane noma lapho ukulawulwa kwe-vibration nokubona kuyizidingo zomkhankaso. Le ndlela yokufaka ejikeleza iphinde ihlinzeke ngezinga eliphezulu lokulawula kokufaka nokuqinisekiswa, njengoba abaqashi belandelela ukumelana nokudonsa, izinga lokufaka, kanye nezindleko zokugcina ukuze kuqinisekiswe amandla e-pile nokufaka okuphelele kwezindawo zokuthwala. Izinsiza ezibekwe ku-excavator ze-screw pile zisebenza ezinhlelweni ezihlukahlukene zabasalela kuhlanganisa ukugcwaliswa kwemigqomo ye-bridge, ama-embankments ezitimela, izisekelo zezakhiwo, izisekelo zeziqongo zokudlulisela, ukufakwa kwamandla avuselelwa, kanye nezinhlelo zokuvuselela ezakhiweni ezikhona. Imishini iyakwazi ukuhlinzeka ngezilinganiso ezihlukahlukene zama-diameters nama-weight, ukusuka ezindaweni ezincane zomphakathi kanye nezitolo ezisikweletu kuze kube kumadivayisi amakhulu neziphatha ezifaka kakhulu. Abafaki bathola izinzuzo ekusebenzeni ngokukhululeka, ukunciphisa izindleko zokuhweba kwemishini, ukuthuthukisa ukufinyelela endaweni, kanye nekhono lokushintsha imishini ebekwe ku-excavator phakathi kwezigaba eziningi zomsebenzi nezinhlelo zokwakha. Ukuhlola izimo zomhlaba kanye nezimpawu kubalulekile ekukhetheni izinsiza, izilungiselelo ze-pile, kanye nendlela yokufaka, kudinga ukusebenzisana okuclose phakathi kwezinhlinzeko zobunjiniyela, abachwepheshe bemishini, kanye nabafaki. Ukuxubana kobuchwepheshe bemishini bokuxhunywa kwe-excavator besimanje namaphinzi wobunjiniyela be-helical piles kuvumela izixazululo zokwakha ezijulile ezithembekile, eziphindaphindekayo, nezisebenza kahle ezizindaweni ezinzima lapho izindlela zokufaka ezivamile ziqhamuka nezikhala.
