Izintambo Zangaphakathi ze-Auger

Izintambo zendawo ezaphakathi zitshengisa umkhiqizo obalulekile kumasistimu wokubhola wesibili ophindwe kabili asetshenziselwa ukwakhiwa kwezisekelo ezijulile kanye nezinhlelo zobunjiniyela bezezimali. Lezi zithuluzi zokubhola ezineziqu noma eziphelele zisetshenziswa ngaphakathi kwalokho okubizwa nge-casing yangaphandle ye-rig ephindwe kabili, zisebenza ngokubambisana ne-casing yangaphandle ukuze kuthathwe umhlaba nezinto zobumba ngesikhathi sokwandisa ukubhola ezindaweni ezidingekayo. Uhlelo lokujikeleza lwezintambo ezaphakathi luvumela amaqembu okubhola ukuthi afinyelele ukulawula okuqondile phezu kokusheshisa kokubhola kanye nokwabiwa kwe-torque, okwenza kube nemfanelo ekusebenzeni kwezinhlelo zokwakha eziyinkimbinkimbi lapho ukubhola okujwayelekile kokujikeleza okukodwa kungasebenzi kahle noma kunganele ngokobuchwepheshe. Indlela yokusebenza kwezintambo ezaphakathi ibandakanya ukugijima okuqhubekayo kwezinto eziyizinsiza nezangaphandle ngejukisa elilawulwayo, kukhulisa ukusondela kokubhola ezimweni ezifana nezifunda ze-clay, umhlaba ophakeme, insimu yezinye zezinto ezisindayo, i-bedrock engashintshanga, kanye nezimo ezihlanganisiwe. Le ndlela yokubhola yehlisa ukuphazamiseka kwizakhiwo zomhlaba ezizungezile futhi inikeza ukuzinza okuhle kokubhola ngaphandle kokudinga ama-additive amakhulu noma ukujikeleza okuqhubekayo kwensipho, okuyinzuzo ikakhulukazi ezindaweni ezibucayi emvelweni nasezindaweni zokwakha ezisemadolobheni. Izinzuzo zomshini ze-drilling yokujikeleza kabili zivumela amaqembu okubhola ukuthi angene ngaphakathi kokhaphozi, amathafa, nezinto eziphazamisayo ezidinga amathuluzi akhethekile noma amahora okubhola aphakeme asetshenziswa ngezindlela zendabuko. Izintambo ezaphakathi ziza ezihlelweni ezahlukene nezilinganiso, ukusuka ezindaweni ezincane zokwakha ama-micropile kuya kumahlozi amakhulu asekelayo izinhlelo ezibalulekile zokwakha izinsiza, imizila yokwakha, izakhiwo eziphakeme, nezakhiwo zasemanzini. Izicelo zezinhlaka eziphezulu zifaka imikhakha ehlukahlukene yokwakhiwa kwemizila ebalulekile, emsebenzini wokwakha izikhumbuzo zeziphakamiso, ukufakwa kwe-pile kwezinsiza ezinamandla, izinhlelo zokubhaliswa komhlaba, ukulungiswa kwezindawo ngezinhlelo eziqiniswayo, kanye nokuhloswe kokubola okujulile ukuze kutholakale ukusizakala kwezisekelo. Ongoti bokwakha bathembela kumasistimu ezintambo ezaphakathi zokufaka ama-caisson, ukuxhasa ukwakhiwa kwe-diaphragm wall, kanye nokuthuthukiswa kwe-secant pile wall ezindaweni ezinezindawo ezibucayi edolobheni lapho izithintelo zezindawo nezithintelo zamazwi kungavimbela ezinye izindlela zokwakha ezijulile. Ukuguquguquka kwale teknoloji yokubhola kuncike emsebenzini wezobunjiniyela bese kuthi uma kuguqulwa ihlukanisa izakhiwo ezikhona, ukwakhiwa kabusha, kanye nokuthuthukiswa komhlaba ngokuhamba kokubhola nokushintshwa komhlaba. Ojobunjiniyela bagcizelela ikakhulukazi izintambo ezaphakathi ngenxa yokukwazi kwazo ukugcina umzila wokubhola uvundlile kanye nokunembile kwemishini, kuqinisekisa ukuhlela kahle kwezinto zokwakha nezokwakha. Izimo zesigcawu ezisuka emhlabathini ophakeme kuya kwi-bedrock ezanelisayo ziwina kumasistimu ezintambo ezaphakathi zokubhola, ezilungiselelwe kahle ezishintshashintshayo zomhlaba nezivimbela ezingalindelekile phansi. Ukuthuthukiswa kokubhola okulawulwa kanye namathuba okubuyisela isikhathi esiqhubekayo okukhona kumasistimu ophindwe kabili kuvumela ukulungiswa okuphuthumayo kokukwanelwa kokubhola uma izimo zomhlaba zishintsha, kusekela ukuhambisana kwesikhathi sephrojekthi nokwethembeka kwemali. Kubakhi bezisekelo nabachwepheshe bokuhlola umhlaba abaphatha izinhlelo eziyinkimbinkimbi zokwakha emadolobheni, ukufakwa kwemikhumbi ejulile, noma izakhiwo ezinzima zokwakha amandla, ubuchwepheshe bezintambo ezaphakathi bukhombisa ukunemba, ukwethembeka, kanye nokuguquguquka kokusebenza okuyisisekelo sokuphumelelisa ukuzenzakalela kwezakhiwo ezijulile.
