Pile foundation pile head concrete pre-stripping assembly and construction method

Abstract

The invention provides a pile foundation pile head concrete pre-stripping assembly and a construction method. The assembly comprises a pre-embedded isolation component, a pre-embedded splitting component, splitting equipment and hoisting equipment. The pre-embedded isolation component comprises main reinforcement sleeves and acoustic testing pipe sleeves. The preembedded splitting component comprises a set of horizontal splitting pipes pre-embedded on a fracture surface. The splitting equipment comprises hydraulic splitting machines. The hydraulic splitting machines are inserted into the horizontal splitting pipes from the two sides to conduct splitting to form the fracture surface during breaking and stripping. The hoisting equipment comprises a lifting tool, a lifting hook and a steel wire rope. The steel wire rope penetrates through the split and broken horizontal splitting pipes and is connected with the lifting hook, so that pile head concrete is stripped off from reinforcements and acoustic testing pipes. The pile foundation pile head concrete pre-stripping assembly can be made of engineering leftover materials and is low in cost. During construction, the fracture surface is formed through the hydraulic splitting machines, and then the pile head concrete can be broken and stripped off. The process can be completed only by one person. The hydraulic splitting machines can provide smooth pile head connecting surfaces to facilitate later pile foundation detection and follow-up construction. The pile foundation pile head concrete pre-stripping assembly is easy to operate, low in technical requirement, good in breaking and stripping effect and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of pile head removal, in particular to a pile foundation pile head concrete pre-stripping component and a construction method. Background technique [0002] At present, in the construction of cast-in-situ piles, because the strength of the uppermost part of the concrete is poor, in order to ensure the strength of the overall pile body concrete, a part is exceeded when pouring concrete, and then the pile head is broken to remove the excess part. When the pile head concrete is chiseled out, manual construction is generally used. The tools are jackhammers, sledgehammers and steel drills. The head is cut off horizontally, and the concrete pile head is broken. At least two people are required to cooperate in the construction, which is inefficient and poses a high safety risk. Secondly, no matter whether hammering or pick is used to break, due to the large number of main reinforcements and the tight grip with the...
