Single-ring porous construction device for removing unsolidified concrete pile head overall

Abstract

The invention relates to a single-ring porous construction device for removing unsolidified concrete pile head overall. The single-ring porous construction device comprises a fan-shaped blade box, a single-ring porous ring body and a power bracket, and is characterized in that the fan-shaped blade box, the single-ring porous ring body and the power bracket are included, the fan-shaped blade box isconnected with the power bracket removably; the single-ring porous ring body is connected with the fan-shaped blade box fixedly, and the lower part of the power bracket is connected with the single-ring porous ring body through a rectangular steel sheet; the power bracket and the rectangular steel sheet are internally provided with water through gas pipes, and the single-ring porous ring body isof a three-ring bearing structure; and a middle ring is provided with a plurality of circular holes, and the bottom surface of the single-ring porous ring body is provided with a sliding block. By using a unique single-ring porous structure, when the sliding block on the lower side of the single-ring porous ring body is located at different positions, the single-ring porous construction device canadapt to concrete piles in different steel bar layers, positions and diameters; overall removal is performed when concrete is unsolidified; and the construction efficiency is high, and secondary cleaning of the concrete is avoided.

Description

technical field [0001] The invention belongs to the technical field of civil construction, and in particular relates to a single-ring porous construction device for integrally cutting uncured concrete pile heads. Background technique [0002] During the pouring of cast-in-place concrete piles, due to vibration, the cement slurry will return upwards and rise together with the air bubbles inside the concrete, forming laitance within a certain range on the top of the pile, so the strength of the concrete at the pile head is difficult to guarantee; When pouring underwater concrete, the mud and mortar mixture at the head of the pile accumulates the most, resulting in loose concrete at the head of the pile, and the strength cannot meet the requirements. Therefore, during the construction of concrete pouring piles, the actual elevation of the pile head is required to be 500-1000mm higher than the design elevation, and the higher part is removed manually or mechanically, which is us...
