Problems solved by technology

[0005] In view of the above problems, the present invention provides a pile hole diameter detection device for supervision. By setting the inner cylinder to rise vertically, the outer support unit is driven to expand outwards against the inner wall of the pile hole, and the pile diameter is directly obtained from the scale set on the inner cylinder. The diameter value of the hole, and the rotation of the outer cylinder relative to the inner cylinder can be measured at multiple points, which solves the need to use shooting tools for shooting and observation in the prior art. The equipment is complicated, the requirements for ambient light are high, the error is large, and the diameter cannot be measured at multiple points. The technical problem of not being able to measure the roundness of the pile hole section

Embodiment 1

[0036] Such as Figures 1 to 3 As shown, a pile hole diameter detection device for supervision includes a workbench 1 erected above the pile hole, and is characterized in that it also includes a diameter measuring component 2, and the diameter measuring component 2 extends into the pile hole to detect the diameter of the pile hole. diameter, the diameter measuring assembly 2 includes:

[0037] Outer cylinder 21;

[0038] Outer support unit 22, the outer support unit 22 is arranged at the bottom of the outer cylinder 21; and

[0039] Inner cylinder 23, the inner cylinder 23 slides relative to the outer cylinder 21, the inner cylinder 23 moves to drive the outer support unit 22 to support the hole wall of the pile hole, and measure the inner cylinder 23 relative to the outer cylinder The distance moved by 21 directly obtains the diameter of the pile hole.

[0040] It should be noted that when measuring the diameter of the pile hole, the inner cylinder 23 rises so that the out...

Embodiment 2

[0051] Such as Figures 4 to 6 As shown, the parts that are the same as or corresponding to the first embodiment adopt the reference numerals corresponding to the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below: the differences between the second embodiment and the first embodiment at:

[0052] In this embodiment, a roundness measurement assembly 6 is also included, and the roundness measurement assembly 6 includes a collar one 61, a collar two 62 and a rotation drive unit 63, and the collar one 61 is sleeved on the outer cylinder 21, the collar 2 62 is set at the bottom of the outer support unit 22 and is sheathed on the bottom end of the inner cylinder 23, the rotation drive unit 63 drives the outer cylinder 21 to rotate, the The outer support unit 22 fits the inner wall of the pile hole to measure its roundness.

[0053] It should be noted that the detection contact part 223 of the outer support unit 22 is p...

Abstract

The invention provides a pile hole diameter detection device for supervision. The pile hole diameter detection device comprises a working table erected above a pile hole, and is characterized by further comprising a diameter measurement assembly, wherein the diameter measurement assembly extends into a pile hole to detect the diameter of the pile hole. The diameter measurement assembly comprises: an outer cylinder; an outer supporting unit, which is arranged at the bottom of the outer cylinder; and an inner cylinder, which slides relative to the outer cylinder, wherein the inner cylinder moves to drive the outer supporting unit to support and abut against the wall of the pile hole, and the moving distance of the inner cylinder relative to the outer cylinder is measured to directly obtain the diameter of the pile hole. The inner cylinder vertically ascends to drive the outer supporting unit to outwards support and abut against the inner wall of the pile hole, the diameter value of the pile hole is directly obtained through scales arranged on the inner cylinder, and meanwhile, the outer cylinder rotates relative to the inner cylinder so as to realize multi-point measurement.

Description

technical field [0001] The invention relates to the technical field of diameter measuring devices, in particular to a pile hole diameter detection device for supervision. Background technique [0002] In the process of building construction, it is often necessary to dig pile holes in order to lay a good foundation for a building, and the quality of the foundation is the foundation of the quality of the entire building, and the pile holes are the foundation of the foundation, so the quality of the foundation is particularly important. During the construction process, it is often necessary to carry out quality inspection on the aperture of the pile, especially the deeper pile hole is extremely inconvenient when inspecting. For this reason, a pile hole aperture inspection device for construction engineering is needed, but the existing detection device During detection, only the distance between a single point and the center of the circle can be measured, and the distance from m...
