Device and method for treating overfilled concrete of underwater bored pile in advance

Abstract

The invention discloses a device and method for treating overfilled concrete of an underwater bored pile in advance. The device comprises a barrel of which the cross section is rectangular, and the bottom end of the barrel is welded at the bottom surface; the bottom surface is provided with a plurality of rectangular grooves; and one side of each rectangular groove is connected with a steel sheetthrough a hinge. According to the device and method for treating the overfilled concrete of the underwater bored pile in advance, the purpose of chiseling away the head of a concrete pile before finalsetting of concrete is achieved, and manual chiseling of the pile head and chiseling operation of the pile head with a large chiseling machine are not required; the construction risk is low; the construction time for chiseling away the pile head is short, and the construction period is not affected; and no secondary disturbance occurs to steel bars.

Description

technical field [0001] The invention relates to the technical field of concrete pouring, in particular to a device and method for advance treatment of overfilled concrete of underwater bored piles. Background technique [0002] In order to ensure the quality of poured concrete, the underwater bored piles generally have an overfilling height of not less than 0.5 meters of concrete, and the overfilling concrete will be chiseled off later. [0003] The traditional treatment method of super-filled concrete is: after the concrete pile body is completely poured, the earthwork is excavated to the base, and the super-filled concrete is manually and mechanically broken. This treatment method has certain disadvantages: 1) Since the concrete has reached a certain strength, the difficulty of demolition in the later stage will increase, which will increase labor and mechanical costs and increase construction safety risks; A large amount of dust was generated during the process, which ca...

Problems solved by technology

This treatment method has certain disadvantages: 1) Since the concrete has reached a certain strength, the difficulty of demolition in the later stage will increase, which will increase labor and mechanical costs and increase construction safety risks; A large amount of dust was generated during the process, which caused noise and air pollution to the environment; 3) The demolition of overfilled concrete became a key process, which increased the construction period of the project; The process leads to twisting and deformation of the steel bar, which needs to be straightened in the later stage, which increases the cost of the construction period and affects the mechanical properties of the steel bar; It is difficult to control the angle of pile head during processing, hanging and pulling, and it is very easy to break the main reinforcement of the reinforcement cage
