AI Technical Summary
Technical Problem
The existing foundation pit support piles cannot be recycled after completing the mission, resulting in the inability to reuse of steel bars and concrete and remain as underground obstacles, affecting subsequent project construction.
Method used
A cast-in-fill pile recovery system based on controllable low-strength materials is adopted to vibrate the pile core material through a vibrator to form a weak unsolidified area between the pile core material and the filling layer, which facilitates later removal and recycling.
Benefits of technology
It realizes convenient and rapid recycling of pile core materials, leaving no underground obstacles, reduces engineering costs and improves construction efficiency.

Abstract
The utility model relates to the technical field of foundation pit supporting engineering, in particular to a cast-in-place pile recovery system based on a controllable low-strength material, which comprises a control box, a vibrator and a pile body core material, and filling layers are arranged on the periphery of the pile body core material and between the bottom end of the pile body core material and the ground. The vibrator is provided with a vibration frequency regulator, a vibration unit and a vibration direction control unit, the bottom end of the vibrator is provided with a hydraulic clamp, the control box is provided with a hydraulic module and a walking module, the pile body core material is vibrated through the vibrator, and a weak non-solidified area is formed between the pile body core material and the filling layer. According to the structure, targeted vibration measures are taken during the material solidification period and before the pile body core material is pulled out, so that the pile body core material is conveniently and rapidly recycled, and no underground obstacle is left.
