Pile hole diameter detection device for engineering management and control method thereof

Abstract

The invention discloses a pile hole diameter detection device for engineering management and a control method thereof, the pile hole diameter detection device comprises a top seat and a bottom seat, a first power mechanism and a detection mechanism are arranged between the top seat and the bottom seat, and the first power mechanism can drive the detection mechanism to move up and down between the top seat and the bottom seat; the detection mechanism comprises a movable disc, an annular plate, a second power mechanism, a plurality of telescopic detection assemblies and an abutting roller, the first power mechanism can drive the movable disc to move up and down between the top seat and the base, and the annular plate is rotationally arranged on the periphery of the movable disc. The detection precision can be improved; an operator can accurately grasp the position of the measurement point by combining the height and the radial direction corresponding to the measurement point, so that the subsequent repair operation on the measurement point is facilitated; the automation degree, the operation efficiency and the detection precision are high; and a more stable supporting effect is achieved, the risk that the device topples over is eliminated, and stable and safe use is ensured.

Description

technical field [0001] The invention relates to the technical field of engineering management, in particular to a pile hole diameter detection device for engineering management and a control method thereof. Background technique [0002] The pile hole is the hole of the poured concrete pile drilled to strengthen the underground foundation and improve the load-bearing capacity and earthquake resistance of the building foundation. After the pile hole is drilled, a reinforcement cage is lowered into the hole, and then concrete is poured. After the concrete is consolidated, it becomes a foundation pile in close contact with the surrounding soil. This method of making piles saves money and construction time compared with driving concrete piles or steel piles, and is a widely used method in modern building construction. [0003] In order to ensure the quality of the project, it is necessary to carry out quality inspection on the diameter of the pile hole during the construction p...

Problems solved by technology

[0004] The purpose of the present invention is to provide a pile hole diameter detection device for engineering management to solve the problem that the sleeve rod cannot be accurately positioned in the pile hole in the prior art On the central axis, it affects the detection accuracy; it can only detect the diameter of the pile hole in a single radial direction, the detection effect is poor, and it cannot flexibly detect the diameter of any part of the inner wall of the pile hole, and the applicability is poor; the degree of automation is low, the operation efficiency is low, and the detection accuracy is low ; Only the bottom end of the connecting plate has a supporting effect, the upper part of the connecting plate is suspended, and the whole device has the risk of falling
