Technical advantages of large diameter vibrating immersed tube gravel 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.
