Munguva pfupi yapfuura, KR90A inotenderera yekuchera rig yeTyhen nheyo inovakwa fekitori nheyo yekusimbisa chirongwa cheLuoyang, Henan Province.Zvinonzi iyo geology ndeyekudzoserwa kwematombo uye silt, kugadzika kwenheyo kunokonzeresa kutsemuka uye kukanganisa kuchengetedzwa kwekuvakwa kwepasi.Maitiro panzvimbo yebasa anosanganisira kutanga grouting kuzadza makatsemuka uye backfill gapu mu strata, inoteverwa nekushandiswa kwekufinhwa kwemurwi kuchera kugadzira hwaro hwerutsigiro rwechimiro chitsva chepamusoro, pakupedzisira kuzadzisa chinangwa chekusimbisa pasi.
Zvinetso zvepurojekiti iyi ndezvi:
1. Kuvaka mufekitari nehupamhi hwepamusoro 12 m, nzvimbo yekuvaka yakamanikana, kuchera dhayamita 600mm uye kuchera kudzika 20 ~ 25m.
2. Iyo geology inonyanya kudzosera silt, matombo makuru uye akawanda, saka maburi ari nyore kudonha.
3. Iyo simende slurry yakaiswa mumitswe uye mapeji yakaguma nekuoma kusina kuenzana panguva yekuchera, zvichiita kuti zvive nyore kutsauka.Kugadzirisa matambudziko aya, mainjiniya kubva kuTyhen Foundation vakagadzira mhinduro yehunyanzvi.Vakasarudza vashandi vane hunyanzvi uye vakakwirisa zvakanakira KR90A rotary drilling rig, vachishandisa musanganiswa weaviri-pazasi jecha auger uye spiral yekuchera misoro.Iyi nzira yakavabvumira kudzora kudzvanywa kweiyo rig uye kutora mukana weiyo yakakwirira torque maitiro, nekubudirira kupinda mukati meiyo backfilled strata.Nekuda kweizvozvo, mari yekuvaka yakaderedzwa kumutengi, zvichiwana rumbidzo yakabvumirana kubva kune vane chekuita neprojekti.
Tysim KR90A rotary drilling rig inoratidzira injini ye86kW, inorema matani makumi maviri neshanu, uye inogona kuboora maburi ane madhayamita anotangira pa400mm kusvika 1200mm, ine hudzamu hwepamusoro hunosvika makumi maviri nemasere.Iyo rig yakagadzirirwa nekuvakwa kwakareruka, zvichikonzera kuderera kwesimba rekushandisa neinjini nekuda kwehuremu hwayo hwakadzikira.Pasi pemamiriro ekuvaka akaenzana, mazhinji einjini simba rinoshanda rakatsaurirwa kumabasa ekuchera.Pamusoro pezvo, matanda ekuchera anoshandiswa neiyo rig akareruka, achibvumira kukwirisa uye kudzikisa kukurumidza kusvika 75m/min pasi pemamiriro akafanana ekuchengetedza.Iyo rig yekutenderera kumhanya inogona kusvika 5r / min, uye simba remusoro rinogona kutenderera nekukurumidza pa8-30r / min.Iyi dhizaini inovimbisa kukurumidza kupinda kwevhu, kuderera kwemafuta ekushandisa, uye nepamusoro pekuvaka kugona.
