Kutshanje, i-KR90A ejikelezayo yokomba isiseko seTyhen yakhiwe iprojekthi yokuqinisa isiseko sefektri yaseLuoyang, kwiPhondo laseHenan. Kuxelwa ukuba i-geology i-backfill yamatye kunye ne-silt, ukuhlaliswa kwesiseko kuya kubangela ukuqhekeka kunye nokuchaphazela ukhuseleko lolwakhiwo olungaphezulu. Inkqubo kwisiza somsebenzi ibandakanya ukugaya kuqala ukuvala iintanda kunye nokuvala izikhewu kwistrata, kulandelwa kusetyenziso lwemfumba ekruqukileyo yokomba ukwenza isiseko senkxaso yesakhiwo esitsha somphezulu, ekugqibeleni kuphunyezwe injongo yokuqinisa umhlaba.
Ubunzima bale projekthi bu:
1. Ukwakhiwa kumzi-mveliso onomda wobude obuyi-12 m, indawo yokwakha imxinwa, i-drilling diameter 600mm kunye nobunzulu bokomba buyi-20 ~ 25m.
2. I-geology ikakhulu i-backfilling silt, amatye amakhulu kunye namatye amaninzi, ngoko ke imingxuma kulula ukudilika.
3. I-sement slurry efakwe kwiintanda kunye nezikhewu zibangele ubunzima obungalinganiyo ngexesha lokugaya, okwenza kube lula ukutenxa. Ukujongana nale mingeni, iinjineli zaseTyhen Foundation zenze isisombululo sobugcisa. Bakhethe abasebenzi abanezakhono kwaye basebenzise izibonelelo ze-KR90A rotary rig yokomba, besebenzisa indibaniselwano yee-double-bottom sand augers kunye nee-spiral drilling heads. Le ndlela yabavumela ukuba balawule uxinzelelo lwe-rig kwaye basebenzise iimpawu zayo eziphezulu ze-torque, bangene ngempumelelo kwi-strata efakwe ngasemva. Ngenxa yoko, iindleko zokwakha ziye zathotywa kumxumi, nto leyo eyafumana indumiso ngamxhelo-mnye kubaxhasi abaphambili beprojekthi.
I-Tysim KR90A i-rotary drilling rig ine-injini engama-86kW, inobunzima obuziitoni ezingama-25, kwaye inokubhoboza imingxunya enobubanzi obususela kwi-400mm ukuya kwi-1200mm, nobunzulu obufikelela kwi-28 yeemitha. I-rig yenzelwe ulwakhiwo olukhaphukhaphu, olukhokelela ekusebenziseni amandla aphantsi yi-injini ngenxa yokunciphisa ubunzima bayo. Ngaphantsi kweemeko ezifanayo zokwakha, uninzi lwamandla asebenzayo e-injini anikezelwe kwimisebenzi yokomba. Ukongezelela, iintonga zokugaya ezisetyenziswayo kunye ne-rig zilula, zivumela ukunyusa okuphezulu kunye nokunciphisa isantya ukuya kwi-75m / min phantsi kweemeko ezifanayo zokhuseleko. Isantya sokujikeleza kwe-rig sinokufikelela kwi-5r / min, kwaye intloko yamandla inokujikeleza ngokukhawuleza kwi-8-30r / min. Olu yilo luqinisekisa ukungena ngokukhawuleza komhlaba, ukusetyenziswa kwepetroli ephantsi, kunye nokusebenza okuphezulu kolwakhiwo.
