Recently,TYSIM foundation low headroomKR300ESrotary excavationDrilling Rig Participating in Construction in GuangzhouBeijing-Guangzhou high-speed railway in Baiyun DistrictLine 5Project.

Baiyun Station, as the passenger transport responsibility of Guangzhou General Railway, is the first super-large hub built according to the planning and construction concept of modern comprehensive transportation hub in Guangzhou. The main contents of the project construction are the construction of Guangzhou Baiyun Station, supporting the construction of Dalang bus preparation station and other related facilities and contact line projects, project planInCompletion of construction in 2023.

KR300ES low headroom rotary drilling rig at the construction site of Guangzhou high-speed railway projectPile diameterFor1000mm,PileDepth28～33Metersbetween the complex geological conditions:There are mainly miscellaneous fill (mainly backfill formation, construction waste particles are larger), silty clay, silty sand (3-6 meters, easy to collapse), round gravel layer, strongly weathered siltstone, medium weathered siltstone.AboveFor backfillFishingSand bucket lead holeAgainLowerAbout 5 meters of casing. Hit to the sandAfterThick mud to prevent water seepage,EnterTube drill for inclined rockIn-depthUse the sand bucket againWill itfish out,SuchIn case of slurry leakage from small karst cave,namelyBackfill cement,Staycement solidificationContinue drilling after.KR300ES low headroom rotary drilling rig (height 10.9 meters) construction height 11 meters, equipped with 300kN.m high torque power head,Appropriate proportion of mud is allocated to protect the wall, so as to solve the problem of quicksand formation construction and strong power to improve the construction efficiency of rock entry. PerfectSolveIt'sIn the construction of the project, the space is small, the pile diameter is large, the depth is deep,difficultProblems such as entering rock.Fast construction and high efficiency Customers make money and win unanimous praise from construction site personnel.
