Ukuqoqwa Kwemininingwane Kwezinhlelo Zokuhamba Zokufaka

Izinhlelo zokurekhoda idatha ze-walking press-in piling ziwukuthuthuka okubalulekile kwezobuchwepheshe ekufakweni kwezisekelo ezithule, ikakhulukazi kwiProject ezindaweni zasemadolobheni ezinomsindo ezivikelwe, lapho ukulawulwa kokushayisana nokwehlisa umthelela wokwakha kudingeka. Ama-piles e-walking press-in, azaziwa nangokuthi ama-footings ashisayo noma izinhlelo zokwakha ezi-press-in ezizolile, asebenzisa ingcindezi eqhubekayo yokuma phezulu ukuze ahambise ama-piles ensimbi noma ama-composite phansi ngaphandle kokuthinta noma ukushayisana. Izinhlelo zokurekhoda idatha ezihlangene nezinhlelo zokubheka ngesikhathi sangempela ziqoqe izilinganiso eziphelele zokufaka konke phakathi nenqubo yokungena, zirekhoda amagugu yük, izinga lokuhamba, nezithombe zokumelana okunikeza onjiniyela impendulo eqhubekayo ekuziphatheni komhlaba nasekusebenzeni kwe-pile ngesikhathi sokufaka. Ukusetshenziswa kwezinhlelo zokurekhoda idatha emisebenzini ye-walking press-in kuvumela ukuqoshwa kwesistimu kokusebenza komhlaba kuzo zonke izindinganiso zokungena kwe-pile. Lezi zinhlelo zihlola unomphela amandla okuphusha aphelele, ukusabalalisa umthwalo wokuphendula, nokumelana kokungena, zakha ama-curve alula okukhuphuka ahlaziya izimo zangempela zomhlaba ezitholwe ngesikhathi sokufaka. Idatha eqoshwe iveza ukuthuthukiswa kwe-skin friction eduze kwe-pile shaft, ukuhamba kokumelana kokugqoka phezulu kwezinhlanga ezahlukene, futhi ibonisa ukushintsha phakathi kwezithako zomhlaba ezihlukene noma amaqoqo we-geo. Le mininingwane yesikhathi sangempela ivumela amaqembu wokufaka ukuba alungise izilungiselelo zehadiwe, abheke izinkathazo ezingaba khona ezifana nezithiyo noma izimo zomhlaba ezingajwayelekile, futhi enze izinqumo zobuchwepheshe eziphuthumayo ukuze kuqinisekiswe ukunembeka kokufaka ama-pile nokusebenza kwezisekelo. Izinhlelo eziphambili zokuvamile zihlanganiswa nezinsiza zokubeka ama-pile, zivumela ukulawula okuqondile kokujula nokuhlelwa kahle kwe-pile nganoma yini ngesikhathi sokufaka. I-walking press-in piling enezinhlelo zokurekhoda idatha ezihlanganisiwe ibonisa ukusebenza kahle kakhulu ekuhlakuleleni izindawo ezixubile zasemadolobheni, ekuhlanzeni izindawo ezikhathele, naseprojekte ezisematheni kwezinsiza ezithintekayo lapho izindlela zokuphusha zendabuko ziya kudala ukushaya okungamukeleki noma umsindo. Idatha eqoqwe iphinde isetshenziswe ukuze iqinisekiswe ukuthi kuhlonishwa izinqubomgomo zekhwalithi ngesikhathi sokwakhiwa, futhi iphepha ubufakazi bokusebenza kwezinga lokufaka ukuze kube nokuvumelana nokwakhiwa. Onjiniyela be-geotechnical basebenzisa izithombe zokumelana ezirekhodiwe ukuhlinzeka ngokuhlobisa nolwazi lwe-borehole, imibiko yokuhlola umhlaba, kanye nokuhlolwa komhlaba lab, behlisa izibalo zamandla okulayisha nokwenza uqiniseke ngezinhlelo zokwakha. Ukurekhodha okuhlelekile kwedatha yokufaka kusiza ekwakheni amamodeli omhlaba athile endaweni futhi kuqinisekisa izindlela zokuhlela ezizovuma phakathi kwezinhlanga ze-pile ezizayo endaweni efanayo yephrojekthi. Izinhlelo zokurekhoda idatha zandisa ukuzethemba nokucaca kwezinqubo zokufaka ze-walking press-in ezindaweni ezehlukeneyo ze-geo, kusuka ezindaweni ezinamathambo kuya kwi-clay nezithako ezixubile ezifaka ama-cobbles nama-boulders. Ngokwakha amarekhodi aqinisekile, aqhubekayo wokusebenza kokufaka isisekelo, lezi zixazululo zokubeka ziphumelela, onjiniyela, kanye nabaphakeli ngeziwasho ezihlanganiswe zokuphumelelayo, ukuqinisekiswa kokusebenza, nokuhambisana kwezobuchwepheshe kuyo yonke imikhankaso yokufaka ama-pile. Ukuhlanganiswa kwe-acquisition edidiyelwe nedivayisi yokufaka ethule, engenamvukuzane kwenza ubuchwepheshe be-walking press-in kube isixazululo esihlabahlosile ezinkingeni ezinzima zokwakha ezidinga kokubili ukusebenza kobuchwepheshe nokuziphatha kwemvelo.
