Isingeniso
Amathuluzi Anchor Wokuzibhoboza: Isistimu yehange yebha elizibhobozayo iqukethe ibha enentambo engenalutho ene-drill bit enamathiselwe ekwazi ukubhola, ukubambelela kanye ne-grouting ekusebenzeni okukodwa.Ibha engenalutho ivumela umoya namanzi ukuthi kudlule ngokukhululekile kubha ngesikhathi sokumba ukuze kukhishwe imfucumfucu bese ivumela i-grout ukuthi ijovwe ngokushesha ngemva kokuphothula ukubhola.I-Grout igcwalisa ibha engenalutho futhi imboze ngokuphelele yonke ibhawodi.Ama-couplings angasetshenziswa ukuhlanganisa amabha angenalutho futhi andise ubude bebhawodi kuyilapho amantongomane namapuleti esetshenziselwa ukunikeza ukungezwani okudingekayo.
Ukukhetha umkhiqizo olungile
Isistimu yehange yebha elizibhobozayo iwuhlelo olusetshenziswa kakhulu lokusimamisa inqwaba yamadwala, ikakhulukazi embonini yokumba umhubhe, izimayini ezingaphansi komhlaba kanye nobunjiniyela bomhlaba.Isetshenziselwa kakhulu ubunjiniyela obusekelayo endaweni evulekile futhi ephukile yedwala enembobo enzima yokubhoboza.Inikeza ikhambi elilungile lokubethelwa kwenhlabathi, ukubopha ukukhiya, ukuphinda kabili.
Isistimu yehange yebha elizibhobozayo ifeza izidingo zamanje nezikhulayo zomhubhe, imboni yezimayini kanye nobunjiniyela baphansi ukuze kukhiqizwe ngokuphephile nangokusheshayo.Uhlelo luhlinzeka ngezinzuzo kuzo zonke izindawo lapho lusetshenziswa khona, lapho ama-boreholes angadinga isikhathi sokumba ngezinhlelo zokufaka ama-casing emhlabathini ongahlanganisiwe noma ohlangene.
Izici Nezinzuzo
Ifaneleka kakhulu izimo ezinzima zomhlabathi.
Ukufakwa okuphumelelayo kusukela ekubhobozeni, ukubeka kanye nokugxusha kungenziwa ngokusebenza okukodwa, konga kokubili isikhathi nemali.
Uhlelo lokuzibhoboza luqeda imfuneko ye-borehole enhlabathini ebhidlikayo.
Uhlelo olusheshayo, olunesinyathelo esisodwa sokubambelela esinezinto ezilula ezikwazi ukusebenza nge-track drill ejwayelekile (isando esiphezulu) noma izinto zokumba ezibanjwa ngesandla, okuqeda isidingo sama-casing rigs amakhulu.
Ukufakwa ngokubhoboza kanye nokugxusha ngasikhathi sinye kungenzeka, kanye nohlelo lokufakwa kwe-post grouting lulula.
Ukubhoboza njalo nokugxumeka ngaphansi kwengcindezi ephezulu kubangela ukuthi i-grout ingene enhlabathini exegayo futhi idale umphumela we-bulb wokwandisa umthamo webhondi.
Ukufakwa kalula kuzo zonke izinhlangothi, nangaphezulu, nezindlela zokufaka ezifanayo kuzo zonke izimo zaphansi.
Ifanele ukusebenza endaweni elinganiselwe, ukuphakama nasezindaweni zokufinyelela okunzima.
Ukugalela umpheme wokuvikela ukugqwala okuthuthukisiwe kuyatholakala uma kunesidingo.
Izinhlobo eziningi zama-drill bits afanele izimo ezihlukene zomhlabathi.
Iphethini yebha ecushwe ngokuqhubekayo ingasikwa futhi ihlanganiswe noma kuphi ngobude bayo ukuze kuzuzwe bonke ubude.
