A prefabricated concrete pipe pile core filling treatment method

Abstract

The present invention relates to a prefabricated concrete pipe pile core-filling treatment method. The prefabricated concrete pipe pile core-fill treatment method adopts the following pipe pile cleaning device. The pipe pile cleaning device includes a mounting frame, a rotating sleeve, a moving column and a cleaning mechanism; The method for core-filling prefabricated concrete pipe piles by the pipe pile cleaning device includes the following steps: S1, pipe pile cleaning preparation; S2, pipe pile cleaning; S3, reinforcement cage placement; S4, pipe pile pouring. The present invention can solve the following problems existing in the cleaning of the inner wall of the pipe pile: the artificial cleaning effect of the pipe pile is poor, and the inner wall of the pipe pile is thoroughly cleaned, which makes it difficult to insert and place the steel cage in the later stage, and the pipe pile whose inner wall is not cleaned thoroughly It will affect the bonding effect of poured concrete and pipe piles; manual cleaning is inconvenient when pipe piles are buried deep, and the accumulated water in pipe piles needs to be extracted separately, resulting in high efficiency of pipe pile construction.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a core-filling treatment method for prefabricated concrete pipe piles. Background technique [0002] Prestressed concrete pipe piles can be divided into post-tensioned prestressed pipe piles and pretensioned prestressed pipe piles. Pretensioned prestressed pipe pile is a hollow cylindrical slender concrete prefabricated component made by pretensioned prestressing process and centrifugal forming method. It is mainly composed of cylindrical pile body, end plate and steel ferrule. [0003] After the concrete pipe pile is buried in the foundation, the upper end of the pipe pile will be higher than the foundation surface. After that, the inner wall of the pipe pile needs to be cleaned, and the accumulated water in the pipe pile should be drained, so that the prefabricated steel cage can be inserted smoothly. In the pipe pile, concrete is poured in the pipe pile afterwar...

AI Technical Summary

Problems solved by technology

[0004] 1. The manual cleaning effect on the pipe pile is poor, and the inner wall of the pipe pile is thoroughly cleaned, which makes it difficult to insert the reinforcement cage in the later stage, and the pipe pile whose inner wall is not cleaned thoroughly will affect the bonding effect of the poured concrete and the pipe pile;

[0005] 2. Manual cleaning is inconvenient when the pipe piles are buried deep, and the accumulated water in the pipe piles needs to be extracted separately, resulting in low efficiency of pipe pile construction.
