The construction method of the installation structure of the foundation pile acoustic measuring tube

Abstract

The invention relates to a construction method for a foundation pile acoustic tube installation structure, which comprises the following steps: 1) construction preparation; 2) pre-assembly of the acoustic tube; 3) connection of the acoustic tube and a reinforcement cage; 4) treatment of cracks in the acoustic tube ; 5) Protective construction of acoustic tube ends. The beneficial effects of the present invention are as follows: the present invention can limit the plane position of the acoustic measuring tube with the help of the built-in support body and the outer limiting body, and can measure and control the axial position of the acoustic measuring tube with the help of the guide positioning plate, so as to realize the sound detection and control. The multi-angle control of the spatial position of the measuring tube; the present invention is provided with a connecting splint, a tie positioning rib and an outsourcing positioning rib between the acoustic measuring tube and the measuring tube positioning hoop, and can be connected and fastened by the positioning rib bolts, reducing the The difficulty of connection construction of the acoustic measuring tube and the damage to the acoustic measuring tube caused by the connection construction are eliminated; the present invention arranges an inner support bladder in the cracked section of the acoustic measuring tube, and injects the bladder filling body in the inner support bladder, so that the acoustic measurement can be realized. Fast closed filling of the tube lumen, preventing concrete from entering the acoustic tube.

Description

technical field [0001] The invention relates to a construction method for the installation structure of acoustic measuring tubes of foundation piles, belongs to the field of foundation engineering, and is suitable for installation and layout projects of acoustic measuring tubes of cast-in-situ piles. Background technique [0002] In bridge engineering, the load-bearing performance of foundation piles is closely related to the quality and integrity of their concrete pouring. At present, the quality of finished cast-in-situ piles is usually tested by the acoustic tube method in engineering. Restricted by the complex construction environment and on-site operation technology, the following situations are prone to occur during the construction of the acoustic tube: the connection between the acoustic tube and the steel cage is not strong enough, and the cracked acoustic tube during production and transportation cannot be rebuilt. In the process of installation, it is easy to lea...

Problems solved by technology

However, the two ends of the acoustic tube are wrapped with waterproof tape, and there is still the possibility of leakage from the middle section of the acoustic tube; at the same time, the connection between the acoustic tube and the steel cage is prone to displacement, and the cracked acoustic tube is wasted. did not improve
