A single-ring porous construction device for integrally cutting uncured concrete pile heads

Abstract

The invention relates to a single-ring porous construction device for integrally cutting off uncured concrete pile heads, comprising a fan-shaped blade box, a single-ring porous ring body, and a power support, and is characterized in that: the fan-shaped blade box, the single-ring porous ring body and a power bracket, the fan-shaped blade box is movably connected to the power bracket, the single-ring porous ring body is fixedly connected to the fan-shaped blade box, the lower part of the power bracket is connected to the single-ring porous ring body through a rectangular steel sheet, and the The power bracket and the rectangular steel sheet are provided with water pipes inside, the single-ring porous ring body adopts a three-ring bearing structure, the middle ring is provided with a number of round holes, and the bottom surface of the single-ring porous ring body is provided with sliders, The invention utilizes a unique single-ring porous structure. When the sliders on the lower side of the single-ring porous ring are in different positions, it can adapt to concrete piles with different reinforcement layers, positions, and diameters, and can be cut off as a whole when the concrete is not solidified. , The construction efficiency is high, and the 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...
