Large diameter vibrating immersed tube rubble pile

Large-diameter vibrating immersed tube crushed stone pile is a deep and large-diameter dense pile body composed of crushed stone formed by sinking the steel feed pipe into the design depth by using high-power vibrating hammer as the driving force, filling the gravel into the hopper and silo, and then pulling out the feed pipe through vibration. Compared with the traditional technology of gravel pile, Shanghai Qiangqiang has mature construction technology and experience, and has dozens of gravel pile construction equipment, which has been successfully used in many large-scale foundation treatment projects at home and abroad.

Lifting scheme of steel cage and lattice column

The elevation of the steel cage and lattice column can be calculated by the elevation at the top of the mouth guard pipe. The design elevation of the pile top must be guaranteed when placed, and the allowable error is ±10mm. The lattice column and the steel cage must be welded firmly, and the vertical deviation is not more than 1/300.
