Munguva pfupi yapfuura, Tyhen Foundation's low headroom KR300ES rotary drilling rig yakatora chikamu mukuvaka kweGuangzhou-Baiyun District Jingguang High-Speed Rail Line 5 chirongwa.
Senzvimbo yekufambisa yevatakuri yeGuangzhou's njanji yedhorobha, Baiyun Station ndiyo yekutanga hombe-hombe hubhu yakavakwa zvinoenderana nemazuva ano akabatanidzwa ekufambisa hub kuronga pfungwa muGuangzhou.Iyo purojekiti inonyanya kusanganisira kuvakwa kweChiteshi chitsva cheGuangzhou Baiyun, pamwe nekuvandudzwa kwezvivakwa zvine hukama zvakaita seDalang Bus Maintenance Depot uye njanji yenjanji.Iyo purojekiti yakarongerwa kupera muna 2023.
KR300ES Yakaderera headroom rotary drilling rig munzvimbo yekuvaka yeGuangzhou yakakwirira-yekumhanya njanji purojekiti dhayamita ye1000mm, murwi wakadzika pakati pe28 ~ 33 metres, geological mamiriro akaomarara: kunyanya kuzadza (kunyanya kudzoreredza kuumbwa, kuvaka marara zvidimbu zvakakura), ivhu revhu. , silt (mamita 3-6, gomba riri nyore kudonha), matombo, dombo rakasimba remhepo, siltstone yakanyungudika.Ivhu repamusoro rinozadza kumashure rine buri rejecha remugomo uyezve anenge mamita mashanu pasi pechubhu.Mushure mekurova danda rejecha, dhaka gobvu rinogadziriswa kudzivirira mvura kuti isapinda.Pinda padombo rakarerekera, chera zvakadzika uye wobva wariredza kunze nemugomo wejecha.Kana slurry ichidonha mubako diki karst, iyo inodzosera simende, uye ramba uchichera mushure mekunge simende yasimba.KR300ES Yakaderera headroom rotary drilling rig (kureba kwemamita 10.9) kureba kwekuvaka kwemamita gumi nerimwe, akashongedzerwa ne300 kN.Iyo hombe torque simba musoro we m inogovera iyo yakakodzera yedhaka reshiyo kuchengetedza madziro kugadzirisa kuvakwa kweiyo quicksand kuumbwa uye simba rine simba rekuvandudza kugona kwekuvaka kwekupinda kwedombo.Iyo inogadzirisa zvakakwana matambudziko anowanikwa munzvimbo diki, yakakura murwi dhayamita, yakadzika yakadzika uye yakaoma dombo.Kuvaka nekukurumidza uye nepamusoro-soro vatengi vanoita mari, vakakunda nzvimbo yekuvaka yevashandi vanorumbidza.
Iyo KR300ES yakaderera headroom rotary drilling rig inoshandiswa munzvimbo yekuvaka yeGuangzhou high-speed rail project, uko dhayamita remurwi i1000mm, uye kudzika kwemurwi kunotangira pa28 kusvika ku33 metres.Mamiriro ezvinhu e geological akaoma uye anosanganisira zvinhu zvakasiyana-siyana senge ivhu rekuzadza rakasiyana-siyana (kunyanya akazadzwa nemashure ane marara makuru ekuvaka), ivhu revhu, jecha rine silt (kubvira pa3 kusvika 6 metres, rinoda kudonha), matombo akakomberedzwa akatenderedzwa, marara ane mamiriro ekunze. sandstone, uye ine mwero mamiriro ekunze ane siltstone ejecha.Kune ivhu rekumusoro rekumashure, bhaketi rinokwesha jecha rinoshandiswa kugadzira casing yakatenderedza 5 metres pasi pepamusoro.
Mushure mekusvika pajecha, dhaka gobvu slurry rinoshandiswa kudzivirira kupinda kwemvura.Paunenge uchisangana nematombo ematombo, chirongo chepakati chinoshandiswa kupinda, chinoteverwa nekushandiswa kwejecha-kuchera bhaketi kubvisa zvinhu.Kana paine maburi madiki kana seepage, simende inoiswa jekiseni, uye kuchera kunoenderera mushure mekunge simende yasimba.
Iyo KR300ES yakaderera headroom rotary drilling rig, ine hurefu hwemamita 10.9, inoshanda pahurefu hwekuvaka yemamita gumi nerimwe uye ine simba re300kN.m torque simba musoro.Inoshandiswa neyakakodzera dhaka slurry reshiyo yekudzivirira kwemadziro, kugadzirisa matambudziko ekushanda mukuyerera kwejecha maumbirwo uye kuwedzera kushanda kwekuvaka pakupinda mumatombo.Iyi rig inogadzirisa zvakakwana nyaya dzakasangana mukuvaka, kusanganisira nzvimbo shoma, dhayamita hombe yemurwi, kudzika kwakakosha, uye kupinza kwedombo kunonetsa.Kumhanya kwayo kukuru kwekuvaka uye kushanda nesimba kwakawana rumbidzo yakabvumirana kubva kune vashandi venzvimbo yekuvaka, zvichizobatsira mutengi.
