Muva nje, i-KR90A Rotary Drilling Rig of Tyhen Foundation yakhiwa iphrojekthi yokuqiniswa kwesisekelo sefekthri saseFectoct Foundation of Luyang, Isifundazwe saseHenan. Kubikwa ukuthi i-geology ihlela kabusha amatshe kanye ne-silt, indawo yokuhlala isisekelo izodala ukuqhekeka futhi ithinta ukuphepha kokwakhiwa okungekho emthethweni. Inqubo endaweni yokugcina imisebenzi ifaka ukulala kuqala ukugcwalisa imifantu kanye nezikhala zokubuyela emuva eStrata, kulandelwe ukusetshenziswa kokuxhaswa kwesisekelo kwesakhiwo esisha, ekugcineni kufezekisa umgomo wokuqiniswa komhlaba.
Ubunzima bale phrojekthi yile:
1. Ukwakhiwa efektri ngomkhawulo wokuphakama ongu-12 m, indawo yokwakha iyinhle, ububanzi bokumba 600mm kanye nokumba okujule 20 ~ 25m.
2
3. I-slurry cement efakwe emfungweni nasezigatsheni zaphumela ekubukeni okungalingani ngesikhathi sokumba, okwenza kube lula ukuphambuka. Ukubhekana nalezi zinselelo, onjiniyela abavela eTyhen Foundation bakha isixazululo sobuchwepheshe. Bakhethe opharetha abanamakhono futhi bathola izinzuzo ze-RR90A Rotary Drilling Rig, besebenzisa inhlanganisela ye-auger ye-sand auger ephindwe kabili Le ndlela yabavumela ukuba balawule ingcindezi yeRig futhi basebenzise izici zayo eziphakeme ze-torque, bangena ngempumelelo strata esetshenzisiwe. Ngenxa yalokho, izindleko zokwakha zancishiswa iklayenti, zithola indumiso engenakuvutha evela kubambiqhaza abaphambili bephrojekthi.
I-Tysim Kr90A Rotary Drilling Rig ifaka injini engu-86kw, inesisindo esingamathani angama-25, futhi ingathwala izimbobo ezinamawazi zisukela ku-400mm kuya ku-1200mm kuya ku-28 metres, ngokujula okuphezulu kwamamitha angama-28. I-Rig yakhelwe ngokwakha okulula, okuholela ekusetshenzisweni kwamandla okuphansi yinjini ngenxa yesisindo sayo encishisiwe. Ngaphansi kwezimo zokwakha ezifanayo, iningi lamandla asebenzayo enjini linikezelwe ekusebenzeni kokumba. Ngokwengeziwe, izinduku zokumba ezisetshenziswe nge-rig zilula, zivumela isivinini esikhulu esiphakanyisiwe kanye nejubane eliphansi elifinyelela ku-75m / min ngaphansi kwezimo ezifanayo zokuphepha. Ijubane lokujikeleza kweRig lingafinyelela ku-5R / min, futhi ikhanda lamandla lingashintsha ngokushesha ku-8-30r / min. Lo mklamo uqinisekisa ukungena kwenhlabathi okusheshayo, ukusetshenziswa kwamafutha aphansi, nokusebenza kahle kokwakha okuphezulu.
