Imishini Yokubhoboza Eziqhulwini Zokuhamba Zokufaka

Imishini yokucaca yomgibeli wethunthi yokubhoboza indawo ye-micropiling imele izixazululo ezikhethekile eziklanyelwe ukuzinzisa okuphansi nokwakha izisekelo ezijulile ezindaweni ezikhethiwe lapho izindlela zokubhoboza ne-piling ezijwayelekile zingasebenzi kahle noma zingasebenzi. I-micropiling, eyaziwa nangokuthi i-minipiling noma i-needle piling, imele isu elithuthukile lokwakha umhlaba elisebenzisa ama-pile amancane anohlamvu oluphezulu, avame ukubalwa ukusuka ku-75mm kuya ku-300mm ngosayizi. Lezi zindlela zibalulekile ekwakheni kwanamuhla, ikakhulukazi lapho kuthuthwa izakhiwo ezikhona, kuhlangatshezwa nezimo ezinzima zokungena emalini, noma kuphathwa ubunjiniyela bendawo obunzima. Imishini yokubhoboza ethunhi ekhethelwe imisebenzi ye-micropiling ivumela abakhiqizi ukuthi benze ukubhoboza okuqondile, okuphephile nokufakela ama-pile endaweni ezincane, kufaka phakathi izingxenye zomgibeli, izindawo ezingaphansi, nezindawo ngaphansi kwezinsiza ezikhona lapho imishini enkulu ejwayelekile ingakwazi ukusebenza kahle. Ukusetshenziswa kobuchwepheshe kwemishini yokubhoboza ethunhi ye-micropiling kuhilela izindlela zokubhoboza ezihamba phambili ezikhipha futhi zisebenze umhlabathi noma itshe ngokusebenzisa izindlela ezihlukahlukene. Ukubhoboza okujikelezayo ngokusebenzisa izinhlelo zokuhamba emuva kuyindlela ehamba phambili, evumela ukuhamba okulandelanayo kokubhoboza nokukhipha izinto ezishaywayo ngesikhathi sangempela, kunciphisa ubungozi bokungabi nembile komgudu emhlabathini ongakhazimulwayo. Ukubhoboza ngephunga nendlela yokubhoboza ye-rotary percussion ihlinzeka izicelo ezidinga ukungena okuqhubekayo emithonjeni edlayo, ngenkathi izindlela zokubhoboza ze-auger zikhuluma ngama-condition omhlabathini okuthambile nemhlaba ophathekayo. Ngemuva kokuphothulwa komgudu, kufakwa ukwakhiwa kwezinye izinto – okujwayelekile okufaka ama-tube wensimbi noma ama-H-beams – kulandela nge-grouting enezinga eliphakeme usebenzisa izinhlelo ze-gravity-feed noma ze-pressure-injection grouting. Ukuxubha kwe-grout kuhluka ngokuya ngohlobo lomhlabathi, izimo zamanzi aphansi, kanye nesidingo se-pile capacity, nezincazelo ezivela ku-gravity grout emathafeni anokungena kuze kube i-sealed pressure grouting emhlabathini ophakanyisiwe noma ophethwe ngamanzi. Imishini yokuhlola ehlanganiswe kumishini yokubhoboza ethunhi yesimanjemanje inikeza impendulo yengcindezi ngesikhathi sangempela, measure torque yokubhoboza, kanye nokurekhoda isivinini sokuhamba, iqinisekisa izinga lokuqina kuzo zonke izinqubo ze-micropiling. Izicelo ze-tunnel micropiling zifaka izimo zokwakha ezihlukahlukene emazingeni omphakathi, ukuvuselelwa kwezinsiza, kanye nezinhlelo ezinzima zokwakha izisekelo. Ukuqinisa izakhiwo nokuthuthukisa izakhiwo zomlando kumasiko amakhulu, lapho izisekelo ezikhona zidinga ukuqina ngaphandle kokumba kakhulu noma ukuphazamisa isakhiwo. Ukwakhiwa kwezitimela nezithuthuthu kuhlinzeka i-micropiling yokuvumelanisa, ukuvikela izakhiwo ezisinamathelayo, kanye nokuxhasa isikhungo, kanti imishini yokubhoboza ethunhi inikeza imishini ebalulekile yokufaka izikhumbuzo noma ezihlelekile. Umsebenzi wezisekelo zezilayini unciphisa i-micropiling ukuze kuziwe ukuvikelwa kokuhlanza, ukuvuselelwa kwezindaweni ezikhaliphile eduze kwezinsika, kanye nokuqinisa kwemifula okuzenzakalelayo. Izimo zomhlaba ezifanele i-micropiling ziqukethe ohlukaniswa kwezodaka ezithambile nezidlakela, kuya kumhlaba ovundlile kanye nezinsimbi ezihlakazekile, nakuba imishini nezindlela kufanele zishintshe ngokuya ngohlobo lomhlabathi oluthile. Izimo zamamali aphansi, ama-aquifers e-artesian, kanye nemhlaba ophazamisayo kudala ezinye izinselelo ezinkulu ezibhekana nezinhlelo ezikhethekile ze-grouting kanye nezinguquko kumklamo wemishini. Ukusebenza kwe-tunnel micropiling kuncike kakhulu ekulawuleni kahle imishini, ulwazi lomsebenzisi, kanye nokukhetha imishini efanele evumelana ne-geology yephrojekthi. Izidingo zamandla, izici zokuzinza komgudu, isikhala esitholakalayo, kanye nosayizi bezindawo zokusebenza zonke zithinta izincazelo zemishini. Idatha yokuhlola umhlaba, kuhlanganisa ama-logs okubhoboza, ukuvota emanzini aphansi, kanye ne-classification yokwakhiwa komhlabathi, ikhuluma ngokukhetha indlela yokubhoboza kanye nomklamo wesistimu ye-grouting. Imishini yokubhoboza ethunhi yesimanjemanje ihlanganisa izindlela zokuhamba okwenziwa ngamakompyutha, ukusabela okuzenzakalelayo kokulinganisa kwe-grouting, ukuqapha i-inclinometry ngesikhathi sangempela, kanye nezinhlelo zokurekhoda ingcindezi, iqinisekisa izinga eliphindaphindiwe kumafekthri e-pile amaningi nokuhlangabezana nezindinganiso ezincike ekwakheni izisekelo ezijulile ezibekwe ngochwepheshe bezobalo nezikhungo zokuphathwa.
