Auxiliary Device and Method for Recovering Forepoling Grouted-Steel Pipe Piles Used in Foundation Pit Support

Abstract

An auxiliary device and method for recovering forepoling grouted steel pipe piles used in foundation pit support, comprising clamps, clamping hydraulic shafts, an upper plane, lifting hydraulic shafts, and a main plane. The clamping hydraulic shafts are mounted on the upper plane, with four shafts installed. The lifting hydraulic shafts are fixed to the main plane, with their output ends connected to the upper plane. Both the upper plane and main plane are designed to sleeve onto the forepoling grouted steel pipe piles. The recovery device and method disclosed in this invention can significantly improve the recycling rate of forepoling grouted steel pipe piles, thereby substantially reducing construction costs. This innovation not only enhances economic efficiency but also actively promotes low-carbon emission reduction during construction, making positive contributions to environmental protection and sustainable development.
