Bored pile bore hole inspection equipment and bored pile bore hole inspection method

Abstract

The invention provides bored pile bore hole inspection equipment. The bored pile bore hole inspection equipment comprises an equipment body (1), multiple distance sensors (2), a direction detection device (3) and a data processing module (4), wherein the distance sensors are equidistantly arranged on the outer side wall of the equipment body (1), and are used for detecting multiple distances between the outer side wall of the bore hole inspection equipment and the inner side wall of a drilling duct in real time in the process of putting the bore hole inspection equipment into the drilling ductto obtain multiple pieces of distance information, the direction detection device (3) is arranged at the equipment body (1) and is used for obtaining direction information of the bore hole inspectionequipment in real time in the process of putting the bore hole inspection equipment into the drilling duct, and the data processing module (4) is arranged at the equipment body (1) and is electrically connected with the distance sensors (2) and the direction detection device (3), and is used for obtaining the direction information and the distance information, correcting the distance informationbased on the direction information to generate multiple pieces of corrected distance information, and generating duct three-dimension information based on the direction information and the corrected distance information.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a bored pile detection device and a bored pile detection method. Background technique [0002] In the existing engineering construction field, the pile foundation is the basic construction foundation of various buildings, so the construction amount of the pile foundation is large, and the safety requirement of the construction is high. [0003] In the current pile foundation construction method, it mainly includes two categories: prefabricated pile and cast-in-situ pile, and according to the different engineering geological conditions on site, as well as the type, section, length, site environment and design requirements of the pile, etc., it has been further developed. Different construction methods. [0004] In the construction process of the pile foundation, firstly, a tunnel is formed by driving piles, then the manufactured steel cage is put into the tunnel, and then ...

AI Technical Summary

Problems solved by technology

[0004] In the construction process of the pile foundation, firstly, a tunnel is formed by driving piles, then the manufactured steel cage is put into the tunnel, and then concrete pouring and other operations are carried out, so as to realize the construction of the pile foundation of the building. However, in the construction of the pile foundation Due to reasons such as the displacement of the drilling rig and the defects of the mechanical operation itself, the verticality of the pile foundation may vary during the piling process, resulting in the deviation of the hole. After the tunnel is completed, the reinforcement cage cannot be lowered normally, resulting in a large number of Rework and waste

[0005] At the current construction site, the construction personnel on the site often put the reinforcement cage directly into the tunnel after the hole drilling of the pile foundation is completed, so as to directly install or inspect the tunnel, which greatly increases the construction cost during the construction process. And it reduces the construction efficiency. If professional tunnel inspection equipment is used, the cost is high, and it is easy to cause accidental damage due to the construction environment on the construction site, which brings additional construction costs and causes great troubles to the construction site.
