Description

Technical Field

[0001] The present invention relates to the technical field of pile foundation hole detection, and more specifically, to a pile foundation hole depth detection device for pile foundation construction and its construction method. Background Art

[0002] In engineering practice, it is found that the problem of reference piles is sometimes overlooked by inspectors, and there are problems such as insufficient driving depth of reference piles and displacement during the test process. This requires pile foundation hole detection, and generally a pile foundation hole detection device is needed for pile foundation hole detection.

[0003] At present, after the pile foundation hole depth detection device detects the depth of the pile foundation hole, when the rope is recovered, it is impossible to clean the mud on the surface of the rope. The mud adheres to the surface of the rope, resulting in an increase in the diameter and weight of the rope. The chemical substances in the mud may corrode the rope material, shortening the service life of the rope. The adhesion of the mud will increase the weight of the rope, making it more laborious to recover and affecting the efficiency.

[0004] Therefore, we make improvements in this regard and propose a pile foundation hole depth detection device for pile foundation construction and its construction method. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that after the current pile foundation hole depth detection device detects the depth of the pile foundation hole, when the rope is recovered, it is impossible to clean the mud on the surface of the rope. The mud adheres to the surface of the rope, resulting in an increase in the diameter and weight of the rope. The chemical substances in the mud may corrode the rope material, shortening the service life of the rope. The adhesion of the mud will increase the weight of the rope, making it more laborious to recover and affecting the efficiency.

[0006] In order to achieve the above-mentioned invention purpose, the present invention provides the following technical solutions:

[0007] A pile foundation hole depth detection device for pile foundation construction and its construction method to improve the above problems.
