Muva nje, i-KR90A rotary drilling rig ye-Tyhen foundation yakhiwe iphrojekthi yokuqinisa isisekelo sefekthri yaseLuoyang, eSifundazweni saseHenan.Kubikwa ukuthi i-geology iyi-backfill yamatshe nodaka, ukuhlaliswa kwesisekelo kuzodala imifantu futhi kuthinte ukuphepha kokwakhiwa kwendawo.Inqubo esizeni somsebenzi ihilela ukukhishwa kwe-grouting yokuqala ukuze kugcwaliswe imifantu kanye nokuvala izikhala ku-strata, okulandelwa ukusetshenziswa kokumba inqwaba enesithukuthezi ukuze kwakhiwe isisekelo sokusekela isakhiwo esisha sendawo, ekugcineni kufezwe umgomo wokuqinisa umhlabathi.
Ubunzima bale phrojekthi yilezi:
1. Ukwakhiwa kwefektri enomkhawulo wokuphakama okungu-12 m, indawo yokwakha incane, ububanzi bokubhoboza buyi-600mm nokujula kokumba 20~25m.
2. I-geology ngokuyinhloko igcwalisa udaka, amatshe amakhulu namaningi, ngakho izimbobo kulula ukugoqa.
3. Udaka lukasimende olwafakwa emifantwini nasezikhaleni lubangele ukuqina okungalingani ngesikhathi sokumba, okwenza kube lula ukuchezuka.Ukuze kubhekwane nalezi zinselele, onjiniyela bakwaTyhen Foundation bakha isixazululo sezobuchwepheshe.Bakhethe ama-opharetha anamakhono futhi basebenzise izinzuzo ze-KR90A rotary drilling rig, besebenzisa inhlanganisela yama-sand augers aphansi kabili namakhanda okumba avunguzayo.Le ndlela yabavumela ukuthi balawule ukucindezela kwe-rig futhi basebenzise izici zayo eziphezulu ze-torque, bangene ngempumelelo ku-backfilled strata.Ngenxa yalokho, izindleko zokwakha zehliswa kuklayenti, okwazuza ukunconywa ngazwi linye kubabambiqhaza abayinhloko balo msebenzi.
I-Tysim KR90A rotary drilling rig inenjini engu-86kW, isisindo samathani angu-25, futhi ingabhoboza izimbobo ezinobubanzi obusuka ku-400mm kuya ku-1200mm, nokujula okukhulu okungafika kumamitha angu-28.Irigi yakhelwe ngokwakhiwa okungasindi, okuholela ekusetshenzisweni kwamandla okuphansi yinjini ngenxa yesisindo sayo esinciphile.Ngaphansi kwezimo ezifanayo zokwakha, amandla amaningi asebenzayo enjini anikezelwe emisebenzini yokumba.Ukwengeza, izinduku zokumba ezisetshenziswa ne-rig azisindi, zivumela ukuphakama okuphezulu nokwehlisa isivinini esifika ku-75m/min ngaphansi kwezimo ezifanayo zokuphepha.Ijubane lokujikeleza le-rig lingafinyelela ku-5r/min, futhi ikhanda lamandla lingajikeleza ngokushesha ku-8-30r/min.Lo mklamo uqinisekisa ukungena ngokushesha kwenhlabathi, ukusetshenziswa kancane kukaphethiloli, kanye nokusebenza kahle okuphezulu kokwakhiwa.
