Pile gripper of vibrating pile hammer with internal supporting type clamping structure and using method of pile gripper

Abstract

The invention relates to the technical field of building foundation engineering, in particular to a pile gripper of a vibrating pile hammer with an internal supporting type clamping structure. The clamping structure comprises a sleeve and a clamping oil cylinder mounted in the sleeve, and a plurality of wedge-shaped pushing blocks are connected with the bottom of the oil cylinder; and the oil cylinder drives the wedge-shaped pushing blocks to move up and down in the axial direction of the sleeve, a plurality of wedge-shaped clamping blocks are matched with the wedge-shaped pushing blocks in position, the matching faces are inclined faces, and the wedge-shaped pushing blocks move up and down in the axial direction, so that the wedge-shaped clamping blocks move in the radial direction of thesleeve and abut against the inner wall of a pile pipe to be clamped after being unfolded outwards. The pile gripper of the vibrating pile hammer with the internal supporting type clamping structure can be embedded into a tubular pile, is propped open and clamps the tubular pile from inside to outside, the problem that a traditional pile clamping device cannot sink into the ground is perfectly solved, the clamping force is larger, and pile sinking operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of building foundation engineering, in particular to a pile clamp for a vibrating pile hammer with an internal support clamping structure. Background technique [0002] Common piling construction methods in the prior art all need pile top to be driven under the foundation pit, namely need a kind of construction equipment that can drive pile top into several meters below the ground. The top of the pile is generally driven into the ground along the pipe pile by a pile clamping machine. However, due to the limitation of the clamping method of the traditional pile clamping machine, the clamping device itself cannot sink into the ground. How to drive the pile top into the ground deep? Become the huge difficult problem that above-mentioned construction method faces everywhere. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the prior art, to provide an ins...
