Cast-in-situ bored pile hole-forming quality detection device and method

Abstract

The invention relates to a cast-in-situ bored pile hole-forming quality detection device and method. The cast-in-situ bored pile hole-forming quality detection device comprises a sonar probe, an integrated operation module and a triangular bracket, wherein the integrated operation module is used for converting information detected by the sonar probe into an image signal and transmitting the image signal to a display, and the integrated operation module is connected with the sonar probe through a cable; and a motor rotating shaft is arranged at the top end of the triangular bracket, the cable is wound on the motor rotating shaft, and the sonar probe is suspended below the motor rotating shaft. By means of the sonar principle, the cast-in-situ bored pile hole-forming quality is detected, accurate information of pile foundation hole forming can be directly and clearly detected, the blank in the professional aspect in the current construction field is filled up, operation is easy, practicability is wide, and generalizability is high.

Description

technical field [0001] The invention relates to the field of building construction, and relates to a device and a method for detecting the quality of holes formed by bored piles. Background technique [0002] Bored piles are widely used in the field of construction engineering. Due to the large pile diameter and deep penetration of bored piles, the hole-forming construction is completed in underground and underwater environments, and the quality control is difficult. Complex geological conditions or wrong construction operations may affect the quality of the pile body, and the pile foundation Excellent hole forming quality is the major premise to ensure the quality and bearing capacity of pile foundation. However, when the pile foundation is formed into holes, it will cause shrinkage or collapse due to loose ground and other reasons before pouring concrete. Therefore, it is of great significance to quickly, efficiently and accurately detect the holes of bored piles. [000...

AI Technical Summary

Problems solved by technology

[0003] However, the current construction technology cannot satisfy the direct detection of the hole formation. Only by lowering the steel cage and observing the amount of tumbled concrete when pouring concrete can one indirectly and roughly know the situation in the underground hole. There is no mature method. The technology inspects the quality of bored cast-in-situ pile holes after the pile foundation is formed and before pouring
