Amathangi eFoam

Imiphumela ye-foam iyithuluzi elikhethekile elibambene nezinsizakusebenza zesimanje ezisebenza kumicro-piling nasemizileni ejulile, futhi ibamba iqhaza elibalulekile ezinqubweni zokubhoboza ezilawulwayo nasekuphumleni. Lezi zimiphumela zenza i-foam ye-pneumatic ngokuhlungisa ukujula kwamanzi okuphuma noma izinsiza zokuphula ngesigqi somoya, zenza umkhiqizo ozinzile, ongenamahloni ophakamisa ukusebenza kokubhoboza nokuthuthukisa ukumelana nezimo ezinzima zomhlaba. Emisebenzini ye-micropiling, imiphumela ye-foam isiza ukukhiqiza ama-foam drilling fluids asetshenziswa ku-hollow-stem auger drilling, open-hole drilling, nasezindaweni zokubhoboza ezivaliwe lapho izinhlelo zemud ezijwayelekile zingasebenzi kahle noma zingafaneleki. I-foam isiza ukwenza kube lula izindonga zomgodi, iyanciphisa ingcindezi ye-hydrostatic ezindaweni ezingazinzile, futhi inciphisa ukufinyelela kwamanzi, okwenza ubuchwepheshe bokuphuma be-foam bube namandla kakhulu emsandleni aphukile, izinsila, ama-clays, kanye nezendlalelo zomhlaba ezigcwele amanzi ezivame ukuvela emsebenzini wokwakha izisekelo ezijulile. Inzuzo eyinhloko yokusebenza kokuphuma kwe-foam ikuma-akhawunti yokusekela ukubhoboza emhlabeni ongalawuleki noma ongezinhle ngenkathi kunciphisa udoti nomthelela kwezempilo uma kuqhathaniswa nemifantu yokubhoboza ejwayelekile. Izinhlelo zokubhoboza ze-foam zenza izinsiza zokubhoboza ezilawulwayo, ezimaphakathi ezishintsha isimo somhlaba, ukusuka kumhlaba ophakeme ukuya kumagquma ahlulekile kanye ne-bedrock. Abasebenzisi bezinsiza bangaphatha ikhwalithi ye-foam kanye nosayizi baphinde balandele izilinganiso zokufaka umoya, izinga lesurfactant, kanye ne-viscosity ye-fluid, beqhuba ukusebenza okuhle kakhulu ngezimo ze-geological ezithile nasemazingeni okungenelela. Imiphumela ye-foam ivame ukuphathwa ngama-motors e-diesel noma we-electric, ibonise izinhlelo zokuphuma ezihambayo noma izinqubo ze-gear pump, futhi ihlanganiswe nezinhlelo ze-compressor zomswakama noma izindawo zokuxhuma zamaswakiwe zodwa. Lezi zinsiza zikwazi ukuphatha izinhlobo ezehlukene ze-fluid—ama-bentonitic muds, amanzi apheshe, noma izinsiza ezikhethekile zokuphula—okwenza kube izinsiza ezisemqoka kumayeter selective aqondisa izisekelo ezahlukene nemigudu yomhlaba emkhakheni ophoqelekile. Ukulawula okuqondile okwethulwa ubuchwepheshe bokuphuma kwe-foam kuvumela abasebenzisi ukuba bafeze ikhwalithi yokubhoboza ye-foam ephindaphindayo ezinhlakeni ezinde zomgodi, kunciphisa ukulahlekelwa kokujikeleza nezinkinga zokungazinzile zomgodi ezivame ukuqubuka kumaphrojekthi endaweni ezimfushane noma ezinzima. Ukuphuma kwe-foam kusekela ngokuqondile izindlela zokugcwalisa ezilula kanye nezindlela zokuthuthukisa umhlaba ezibalulekile emisebenzini yokwakha izindawo zedolobha nezinhlelo zokukua nokubuyisela. Lapho kuhlanganiswe nezinhlelo zokuphula, imiphumela ye-foam ivumela ukukhiqizwa kwe-concrete ye-cellular noma impahla yokusebenza ezinesikhumo esilawulwayo (CLSM), etholakala njenge-backfill elula, ukuphusha izikhala, kanye nezinto zokuxhasa umhlaba ezithile noma ezihlala zikhona. Emsebenzini wokwakha ama-micropile nasezinhlelweni zokwakhiwa, ukwakhiwa okusekelwe ku-foam kuthuthukisa uxhumano phakathi kwezingxenye ze-micropile nomhlaba onjengokuhlunga, ukuqinisekisa ukulandelela komthwalo okungaguquguquki kanye nesikhathi sokuphila eside somsebenzi owakhiwe. Ngaphezu kwalokho, ubuchwepheshe bokuphuma kwe-foam buhlinzeka ngezinsiza eziphakeme zokukhonza ngesikhathi sokubhoboza, kuthuthukisa ukuphepha kwendawo kanye nokuhambisana nemithetho yezehlakalo, ikakhulukazi ezindaweni ezicacile noma ezinhle kakhulu lapho izinqubo zokuhlola umoya zifaka imikhawulo emithini ejwayelekile yokubhoboza. Izinzuzo zokusebenza ze-foam drilling—imirhumo yephuca, ukunciphisa izinkinga zokuhamba kancane, kanye nokunciphisa izidingo zokubuyisela umgodi—zishintsha zibe izinzuzo ezilinganiselwe nokuphumelela kokuhlola imisebenzi emikhakheni yezenzakalo ezijulile lapho ukuqedwa okubalulekile kukhulu.
