Tsis ntev los no, Tyhen Foundation KR285CS qis headroom rotary drilling rig tau tsim nyob rau hauv qhov project ntawm Nongfu Spring hauv Hangzhou. Qhov project no tau tsim nyob rau hauv lub Hoobkas, nrog rau qhov siab txwv ntawm 11 meters thiab qhov chaw nqaim. Lub qhov taub ntawm qhov chaw yog 600mm, thiab lub qhov tob yog li 6 ~ 18m. Lub geological tej yam kev mob feem ntau muaj backfill av khaubncaws sab nraud povtseg, xuab zeb txheej, backfilled limestone, thiab sandstone, ua rau geological kev tsim kho tej yam kev mob kuj complex. Lub backfilled limestone muaj ib tug loj ntim, nrog particle loj li ntawm 200 mus rau 2000mm. Drilling tau muaj kev cuam tshuam loj rau ntawm phab ntsa borehole thiab sab hauv, ua rau nws muaj kev cuam tshuam rau borehole vau thiab pob zeb dislodgement. Raws li cov khaubncaws sab nraud povtseg muaj cov pob zeb loj, suav txog ntau dua 80% ntawm cov ntsiab lus, siv cov casing ntev rau kev tiv thaiv phab ntsa thaum lub sijhawm tsim kho hauv tsev tsis ua tau. Txhawm rau txo cov nqi rau cov neeg siv khoom, tom qab drilling los ntawm cov phab ntsa tawg borehole, cov av liab los yog av nplaum tau siv rau backfilling limestone. Tom qab ntawd cov khoom siv rov qab tau compacted kom nruj, ua rau kev tsim kho nyuaj. Cov txheej txheem drilling yuav tsum tau nkag mus rau hauv pob zeb los ntawm 2 meters, muab qhov kev ruaj ntseg, kev ntseeg siab, thiab kev txiav txim siab muaj peev xwm ntawm qhov drilling rig thiab tus neeg teb xov tooj mus rau qhov kev xeem. Nrog kev txhawb nqa tag nrho ntawm Tyhen cov kws tshaj lij kev tsim kho lub hauv paus, kev ua haujlwm drilling tau ua tiav tiav, tau txais kev qhuas los ntawm tus tswv qhov project.
Tyhen Foundation tsis tshua muaj lub taub hau tag nrho hydraulic teb drilling rig series: KR125ES, KR285CS, KR300ES, KR360CS tau lees paub thiab qhuas los ntawm cov neeg siv khoom txij li lawv tau pib ua lag luam thiab yeej kev ntseeg siab thiab kev txhawb nqa ntawm cov neeg siv khoom. Tyhen low-headroom full-hydraulic rotary drilling rigs tau siv nyob rau hauv Hubei Wuhan Subway No.11 Kab, Shenzhen Guangming City High-speed Railway, Shenzhen Tiegang Shiyan Reservoir, Jiangxi-Shenzhen High-speed Railway, Shenzhen Guangming City Station Junction, Shenzhen Metro Dayun City Subway Station, Fujian Jingtai High-speed Railway, Quanzhou High-speed Railway Station, Shenzhen Longgang Subway Station, Guangdong Shantou High-speed Railway Station, Jiangxi Lushan Railway Station, Guangxi Liuzhou Liugong Factory Building Expansion Project, Shenzhen Baoan District Rain thiab Dej Hiav Txwv Diversion Pipe Gallery Project, Shenzhen Metro Nanshan Qianjin Road Hub Project, Guiyang Riverside Theatre Project thiab lwm yam dej num loj. Tyhen Foundation yuav tsis hnov qab lub hom phiaj tseem ceeb, ua raws li lub tswv yim tseem ceeb ntawm "tsim kev pabcuam tus nqi", thiab ua haujlwm ua ntej.
