Imisebenzi yokudlula imele indlela eyakhelwe phezu kokufakwa kwezindawo ezincane nezokuhlinzeka, isebenzisa izindlela zokubhoboza nezokushaya ezisuselwa kumaphushana ukuze kufakwe ama-pile ancanyana anqamulelayo ezimeni ezinzima zomhlabathi nezinsimu. Ama-drifter angamathuluzi wokushayisa okuphezulu noma ama-hydraulic athola ukuhamba ngokuqhubekayo ngezinto eziqinile, emhlabathini ophakanyisiwe, nasezintabeni eziphukile lapho izindlela zokubhobhoza ezijwayelekile zingase zithathe isikhathi eside noma zibe nezindleko eziphezulu. Lezi zinsiza zibaluleke kakhulu ezindaweni zasemadolobheni nasezindaweni eziqukethe indawo encane lapho ama-micropile ahlinzeka ngezixazululo zokuxhasa izimpande, ukuqinisa ukuphakama, kanye nokuxhasa umthwalo ophindwe kabili ezakhiweni. Indlela yokudlula ihlanganisa ukunemba kwebhizinisi lezindawo ezincane ngamandla nesivinini sokubhoboza okuboshwe, okwenza kube ukukhetha okungabizi kumaphrojekthi adinga ama-pile amaningi anqamulelayo ukufakwa ezimeni zomhlabathi ezishintshashintsha ngaphandle kokwelapha umzimba omkhulu noma ukuhanjiswa kwamanzi. Ukwakha indlela yokudlula kuhilela ukusebenzisa amathuluzi wokudlula ngaphakathi kwembobo (DTH) noma ama-drifter aphezulu afakwe ezikhungweni zokubhoboza, asebenzisa amandla aphakeme okushaya ukuze akhe izimbobo zokuqala noma ashaye amakhasi ngqo emhlabathini. Lezi zindlela zokushaya, ezishajwe nguMoya ophakanyisiweyo noma amasistimu e-hydraulic, ziletha izinkulungwane zokushaya ngaphezu komzuzu, zivumela ukuba i-drifter bit isheshiswe ngokuhamba phambili kudinga izinto ezinzima nezicini ezinzima zomhlabathi. Abasebenzisi sebebhekene nokuqhubeka kokujula kokufaka nokuqinisa kokukwazi ukushayisa eficientes ngenkathi begcina ukubhaliswa kwehole. Inqubo yokufaka ngokujwayelekile ihilela ukusungula imhole ezinzile ngokusebenzisa i-drifter, bese kuqhubeka ukufakwa kwama-micropile casing ezindaweni ezixoshelekile noma ezihlangene. Ukuhamba phambili kudlula kukhombisa ukusebenza kahle emadwaleni aphakathi kophaka, umehluko, ama-sand aqinile, nenhlaka ethobekile lapho ukugaya okujwayelekile kuhamba kalula noma kungathathi isikhathi eside. Le ndlela itholakale nasezimo lapho ukujikeleza kwegazi kubekwe phansi noma lapho abaqashi befuna ukunciphisa ukushaya nezwi, okwenza kube ukukhetha okuhle ezindaweni ezibucayi zasemadolobheni noma eduze kwezinto ezikhona. Ukwakha ama-micropile esekelwe kumadlalelo we-drifter kutholakala emisebenzini yeziqondiso zempahla ezihlanganisa ukunakekelwa kwezimpande zezakhiwo zezakhiwo eziningi ezidinga ukuhlinzekwa, ukuvuselelwa kwezintaba, kanye nezinhlelo zokuxhasa umthwalo wezinsiza ezinkulu, njengama-abutment ezindaweni ezimele. Le ndlela ikhululekile kumaphrojekthi abangelwe ukufinyelela okukhawulelwe, isikhala esiphansi, kanye nesidingo semigqa yokwakha enamandla, encane. Izigcawu zomhlabathi ezihambelanayo nokudlula zifaka ama-clays aphakanyisiwe, imithombo ephakamasile, indalo ye-rock, kanye nezindawo ezishintshana phakathi komhlabathi nezidladla lapho ukugaya okujwayelekile kudinga izindleko eziphezulu. Abakwaqashi bahola ekuguquguqukeni kwezinhlelo ze-drifter, ezingafakwa ezikhungweni zokubhoboza ezilinganiselwe noma ezindizayo, kuvumela ukusatshalaliswa ezindaweni ezinzima nezikhulu. Ukuhlanganiswa kwamandla okuqala kanye nekhono lokugaya kuholela ekwenzeni phambili okusheshayo, ukunciphisa isikhathi sokushintsha amakhaza, kanye nokusebenza okujwayelekile emigoleni eyahlukene. Imisebenzi yokudlula ikhiqiza imhole ezinzile ehambelana nezidingo zokuqinisa amakhasi nokuhluku, okuyisisekelo sokwakheka okuhle nokuphakanyiswa kwama-micropile.
