Izinsiza Zokugruva zeJet eziphakathi

Emkhakheni wokwakhiwa kwezimiso ezijulile nokwandisa isayensi ye-geotechnical, ama-rig amaphakathi e-jet grouting adlala indima ebalulekile ekuthuthukiseni izakhiwo zomhlabathi nokuqinisekisa ubuqotho bezakhiwo. Lezi zingxenye ezikhethekile ezimile ezinomugqa, zenzelwe ukwenza i-jet grouting, indlela ethinta ukufaka i-grout ye-cementitious emhlabathini podlile kwi-high pressure ukuze kudalwe i-solidified soil mass. Le ndlela ikhethekile kakhulu ekuthuthukiseni umhlaba, ivumela abakhakha ukuba bashintshe izakhiwo zomzimba nezokusebenza zomhlabathi, ngaleyo ndlela estabilizira izimo zomhlabathi ezinzima. Ukusebenza kwama-rig amaphakathi e-jet grouting kusekelwe emthethweni olula kodwa osebenzayo. Le mishini isebenzisa amapompo aphezulu ukuze ifake i-grout nge-nozzles ezikhethekile, ezingakha umjikelezo ophakeme. Njengoba i-jet ifaka emhlabathini, ithutha futhi ixube ama-particles omhlabathi ajikelezayo ne-grout, kuholela kumxube olinganiselayo. Le nqubo idala amakholomu noma ama-panels omhlaba athuthukisiwe, angathuthukisa kakhulu amandla okuphatha, anciphise ukuwa, futhi unciphise ukuhanjiswa kwamanzi aphansi. Ukungaguquguquki kwe-jet grouting kuwenza ube yisisombululo esisebenzayo kubabhalisi abababhekene nezinselele zesimo se-geological ezihlukene. Ama-rig amaphakathi e-jet grouting ahlale efanelekile ezinhlelweni ezifana nokufaka, ukuvuselela ama-slopes, ukwesekwa kokumba, kanye nokwakhiwa kwezinsiza ezingaphansi komhlaba. Njengoba evame ukusetshenziswa ezindaweni zasemadolobheni lapho isikhala silinganiselwe futhi izindlela zendabuko ezifana nokushaya ama-pile zingase zingabi nendlela, lezi zikhungo nazo zifaneleka kahle emiphakathini edinga ukucaciswa kwezakhiwo ezinembile nokujula kwekholomu ye-grout, vumele abakhakha ukuba bahlale benze izixazululo ezihambisana nezimo ezithile zezindawo. Izincazelo ezivamile zama-rig amaphakathi e-jet grouting zihlanganisa ubukhulu bokumbiwa obuphakathi kuka-15 kuya ku-30 amamitha kanye nokwaziswa ukufaka i-grout ku-pressure efika ku-200 bars. Lezi zikhungo zifakwe nezinhlelo zokulawula ezithuthukile ezihlola amazinga flow e-grout, pressure, kanye neziqondiso zokufaka, ziqinisekisa ukusebenza okukuhle kanye nezinga lokulawulwa kwekhwalithi. Umklamo ozigxile ezintweni ezihambayo ulethe ukuhamba okuhle kanye nokuma okuhle ezindaweni ezihlukene zomsebenzi, ikakhulukazi ezindaweni ezinzima noma eziluhlaza. Uma ukhetha i-rig ephakathi ye-jet grouting, kufanele kubhekwe izinto eziningana ukuze kuqinisekiswe ukusebenza okuhle. Izici ezifana nokuhamba kwemishini, amandla okumbiwa, kanye pressure yokufaka i-grout kubalulekile ekuvumelaneni kwemishini nezidingo ezithile zephrojekthi. Ngaphezu kwalokho, ulwazi lomphakathi kanye nokutholakala kwesevisi yezobuchwepheshe kubalulekile ukuze kuzuze ukusebenza kahle nokukhiqiza kwe-rig. Ngamafuphi, ama-rig amaphakathi e-jet grouting ayimpahla ebalulekile emkhakheni wokwakhiwa kwezizinda ezijulile nasemkhakheni wezobuchwepheshe be-geotechnical. Ikhono lawo lokuthuthukisa izakhiwo zomhlabathi nokuhlinzeka ngensizakalo eqinile yomhlaba lenza libe nemfuneko kakhulu emabhizinisini abhekene nezinhlelo eziyinkimbinkimbi. Kungakhathaliseki ukuthi kuthengiswa noma kukhunjulwa, lezi zikhungo zimele ukutshala imali okuhle emabhizinisini abafuna ukuthuthukisa amandla abo okubambisana emisebenzini yokuthuthukisa umhlaba.
