Amathuluzi Omzimba Wokwandisa

Ukuhlinzwa kokuphuma okuphelele kokushisa kusetshenziswa amathuluzi omzimba ophakeme kumelana nezindlela ezikhethekile nezisebenza kahle kakhulu zokwakha izisekelo eziqine ezimweni zomhlabathi ezinzima. Amathuluzi omzimba ophakeme ayizakhiwo ezakhiwe ukuba zandise ngendlela ye-radially ngesikhathi sokufakwa kwezinsika, zishiya umhlabathi ngokuhamba kwe-lateral ngaphandle kokungena kwe-borehole futhi ziwugcina njalo ethubeni lesinsika. Le ndlela yokuhlinzwa idala umkhawulo ophakeme, ohlanganyelwe wombala wombhala ophakeme okwandisa kakhulu amandla okuthwala isinsika uma kuqhathaniswa nezindlela ezivamile zokumba noma zokushaya. Umzimba ophakeme usebenza ngokubambisana nomgogodla omkhulu wesinsika, wandisa ngezikhathi ezichaziwe noma ngokuqhubekayo ubunzima bokufakwa ukuze wandise uk transferred stress ye-radial futhi yehlise ukuhamba ekyeni elibunjiwe nasekukhanyeni. Le ndlela yokuhlinzwa kokuphuma okuphelele ibaluleke kakhulu kubathengisi abasebenza emaphrojekthini lapho kuthuthukiswa umhlaba, ukuqiniswa komhlaba, kanye nokwandiswa kokuthwala isisindo kubalulekile ezicini zokwakha. Amathuluzi omzimba ophakeme afakazela ukuhamba okubanzi kweziphakamiso zomhlaba, kufaka phakathi i-clay, i-silt, i-sand, kanye nezimo ezihlanganisiwe ezivame ukutholakala ezindaweni zokwakha zedolobha nezokuthuthukiswa komkhakha. Ukuhamba okuphathwayo komhlaba kudala ibhande lok pressure elivikela eliqinisekisa ukusebenza kahle kokuhamba emaphakathini aphumile futhi ahlulekile, kuhlomula ukwenza umthwalo kumakhanda amisiweyo, aqinile angaphansi. Le ndlela ikhipha isidingo sokufaka isigaba sokungena kwe-borehole ezinhlelweni eziningi, ithuthukisa ukusetyenziswa kwayo futhi inciphise umthelela wemvelo ezindaweni ezithintekayo. Abathengisi bathola inzuzo yokulawulwa kokujula, ukusondela okuncane komhlaba, nethuba lokufaka izinsika ezinezinga eliphakeme lesakhiwo ngisho nasendaweni ezithintwayo noma phansi kwezakhiwo ezikhona. Imishini nezindlela ezisetshenziswa kokuhlinzwa komzimba ophakeme zihlanganisa ama-hydraulic rams, izinhlelo zokwandisa ezikhiqizwayo, kanye nezinsika ezikhethekile ezakhiwe ukuze zikwazi ukumisa kokubili ukuvinjelwa kanye nemithwalo ye-radial. Imigodi yokumba eqhutshwa ngama-Kelly bars, izinduku zokujikeleza, nezinhlelo zokubheka ingcindezi ziqinisekisa ukufakwa kwezinso ngendlela efanele kanye nokuhlelwa kokwandisa okuphawuleka. Le ndlela ivumela izinhlaka ezihlukahlukene zezinso, kuhlanganisa ezijikelezayo, ezikweze, nezithombe ezikhethekile, okwenza kube lula ukuphendukela ezidingweni ezahlukahlukene zokwakha izisekelo. Izindlela zokufaka ziqinisekiswa ngokuqhubekayo ngokuqoqwa kwedatha ngesikhathi sangempela, kubandakanya ubude bokushelela, ama-logs engena, kanye nezilinganiso ze-torque, kuvumela abathengisi ukuba qinisekise ukuthi izidingo zokuhamba komklamo zifezekisiwe ekuthathweni okuyiwo wonke. Amathuluzi omzimba ophakeme asetshenziswa kabanzi emaphrojekthini wezokwakha, okuhlanganisa izinkampani zeofisi, izinsiza zokuhweba, izikhungo zokuhamba, kanye nemigudu yezigcawu lapho ukulawulwa kwesikhunta nokuthwala kwesisindo kumqoka kakhulu. Le ndlela inikeza ukusebenza okuvelele emsebenzini wezisekelo ezithuthukisiwe, ukusebenza kwemisebenzi yokuxhasa, nezinhlelo zokuthuthukiswa komhlaba lapho izakhiwo ezikhona zidinga ukwesekwa okwengeziwe. Izinzuzo zemvelo zifaka phakathi ukuncishiswa kokuphuma kwezinso nokuphuma kwekhonkrithi, ukunciphisa umsindo nezimpawu zokuhamba uma kuqhathaniswa nezinketho ezihambayo, kanye nokunciphisa ukuphazamiseka ezindaweni eziyizithakazelo nezinsiza. Imodi yokuhlinzwa kokuphuma okuphelele ngokusebenzisa amabhodi aphakeme inikeza abathengisi isixazululo esiqinile, esiqondile, nesiphusile sokufeza izinjongo zokwakha ezijulile ezimweni zezimbiwa eziyinkimbinkimbi ngenkathi kugcinwa izindleko ezifanelekile kanye nesikhathi sokuthobela.
