Nguva pfupi yadarika, Tyhen Foundation's Low Mhezheni Kr300es Rotary Drilling Rig yakatora chikamu mukuvakwa kweGuangzhou-Baiyun District Jingguang High-Speed Rail
Sezvo muchengeti wepamberi Hub for Guangzhou's Urban Rail System, Baiyun Station ndiyo yakakura-chiyero Hub yakavakwa maererano neyekufambisa kwekufambisa HUB kuronga pfungwa muGuangzhou. Iyo purojekiti inosanganisira kuvakwa kweNew Guangzhou Baiyun Station, pamwe nekuvandudzwa kwenzvimbo dzakabatana dzakadai seDalang bhazi rekuchengetedza depot uye kubatanidza mitsara yechitima. Iyo purojekiti yakarongerwa kupera muna 2023.
Kr300es Low Low Rotary Drilling Rig muCommunst Site siltstone. Iyo yepamusoro yekumusoro ivhu ine jecha bucket gomba uyezve anenge mashanu metres pasi pehubhu. Mushure mekurova jecha layer, dope matangi anogadziridzwa kudzivirira kutsvaga kwemvura. Isa iyo inoda dombo, ichidhira zvakadzika uye tobva tasiya neiyo jecha ndoo. Kana iri yekubhururuka slurry mune diki karst bako, iyo inosimba simende, uye ramba uchidhiraira mushure me simenti inosimbisa. Kr300es yakaderera musoro kutenderera kufambisa rig (kureba kwe10,9 metres) kukwirira kwekuvaka kwemamita gumi nemaviri, yakagadzirirwa ne 300 kn. Iyo hombe torque simba musoro wemusoro wemubhadharo wakakodzera madhaka kuti udzivirire madziro kuti ugadzirise pakuvakwa kweanokurumidza kuumbwa uye simba rine simba rekuvandudza kugona kwekuvaka kwekupinda kwedombo. Izvo zvinogadzirisa zvinetso zvakasangana nematambudziko madiki, dombo rakakura redhimoni, pakadzika yakadzika uye dombo rakaoma. Kuvakwa nekukurumidza uye zvakakwirira zvinobudirira vatengi vanoita mari, vakakunda nzvimbo yekuvaka vashandi vevashandi.
The K300es Low Low Rotary Drilling Righing Rig inoshandiswa munzvimbo yekuvaka yeGuangzhou High-Speed Rithil, Pile Yakadzika kubva pamakumi masere kusvika 28 kusvika pamamita makumi matatu nemasere. Mamiriro ezvinhu ega ega ega akaomarara uye anosanganisira zvakasiyana-siyana zvakadai sekusanzwisisika ivhu Kune iyo yepamusoro yekudzokera kumashure ivhu, bhakiti rejecha rinoshandiswa rinoshandiswa kugadzira casing kutenderera 5 metres pazasi pechiso.
Mushure mekusvika iyo jecha layer, matavi akakora slurry anoshandiswa kudzivirira kupindurwa kwemvura. Paunenge uchisangana nematombo ematombo, bhara repakati rinoshandiswa kupinda mukati, ichiteverwa nekushandiswa kweiyo jecha bhakiti kubvisa zvinhu. Kana iri madiki madiki kana kuona, simende ine jekiseni, uye kucherwa kunoenderera mberi kwesimende kusimbiswa.
The kr300es yakaderera musoro unodzikira Iyo inoshandiswa neyakakodzera matope madhiraini yekudzivirirwa kwemadziro, kugadzirisa matambudziko ekushanda mune inoyerera jecha mafomu uye kuwedzera kugona kwekuvaka kana uchipinda mumatombo emabwe. Iyi rudzi inogadzirisa zvakanyatsogadzirisa nyaya dzakanyatsogadzirisa mukuvaka, kusanganisira shoma nzvimbo, yakakura dhayimendi, kudzika kwakadzika, uye kudhakwa kwedombo. Kumhanya kwayo kwekuvakwa nekukasira kwakawana rumbidzo isingagone kubva kune yekuvaka saiti vashandi, pakupedzisira vachibatsira mutengi.
