Description

Technical Field

[0001] The utility model belongs to the field of inspection of expanded hole side walls of expanded hole piles in foundation engineering, in particular to an expanded hole side wall inspection device. Background Art

[0002] The bearing capacity mechanism of bored piles indicates that the quality of hole formation and support formation is a key factor in determining the effectiveness of bored pile construction. In traditional bored pile construction, the hidden nature of the hole expansion process makes it impossible to visually measure and monitor the process. Consequently, the control of hole quality relies entirely on the experience and judgment of on-site technicians and managers, lacking effective monitoring methods and tools.

[0003] At present, the construction process still uses traditional measuring tools. In actual operation, workers often use the diameter of the hole expansion area to make a simple tool for measuring the hole expansion diameter. That is, a steel bar is made with the hole expansion diameter to measure whether the hole expansion meets the design requirements. Two workers tie two measuring ropes to the two ends of the steel bar, place it obliquely to the bottom of the hole expansion area, straighten the measuring rope horizontally and slowly rise it to roughly measure whether the hole expansion diameter and hole expansion height meet the design requirements. During the inspection process, the light at the bottom of the hole is poor and the line of sight is blocked. The actual operation error is extremely large, and the hole quality and on-site safety are difficult to guarantee. It is very easy to be restricted during use. Utility Model Content

[0032] Example 1

[0033] refer to Figure 1 As shown in the figure, a side wall inspection device for a hole expansion 201 is shown, and the side wall inspection device for a hole expansion 201 includes: a hole positioner 101, an adjustable screw rod 102 and an umbrella-type frame 103.

[0034] Preferably, the umbrella frame 103 is fixed to the bottom end of the adjustable screw 102. The umbrella frame 103 controls the expansion diameter of the frame via a cable; the cable extends through the center hole of the adjustable screw 102 to the operating end of the adjustable screw.

[0035] Preferably, the adjustable screw 102 passes through the central sleeve 101 a of the orifice locator 101 .

[0036] Furthermore, the orifice locator 101 is a cylindrical structure, which helps to assist in the alignment of the central sleeve 101a and the orifice to be inspected.

[0037] Furthermore, the central sleeve 101a is vertically arranged. Through the vertical structure of the central sleeve 101a, the adjustable screw rod 102 can move in the vertical direction, thereby ensuring that the umbrella-type frame 103 does not tilt during the upward and downward movement.

[0038] Preferably, a stopper structure is provided on the side wall of the central sleeve 101a to lock the adjustable screw 102. If the umbrella frame 103 becomes stuck during inspection, it can be determined that the corresponding depth position is not reamed up to standard, and the stopper structure can be used to lock the adjustable screw 102 in position, helping the operator to record and confirm the corresponding depth.

[0039] Preferably, the adjustable screw rod 102 is formed by splicing together a plurality of screw rod segments 102a, so that the device can be applied to different depths.

[0040] Preferably, each screw rod segment 102a has a threaded structure at its end, and adjacent screw rod segments 102a are connected to each other via a threaded sleeve 102b. Each screw rod segment 102a is a hollow structure to facilitate the passage of a cable.

[0041] Preferably, the side wall inspection device for the expansion hole 201 is a metal structure.

[0042] When inspecting the side wall of the expanded hole 201, the hole opening locator 101 is fixedly arranged at the surface opening of the hole to be inspected.

[0043] When inspecting the side wall of the expanded hole 201, the central sleeve 101a is arranged to coincide with the center of the hole to be inspected.

[0044] When inspecting the sidewall of the reaming hole 201, the umbrella-shaped frame 103 moves vertically along the reaming hole 201. If the umbrella-shaped frame 103 becomes stuck during the inspection, it can be determined that the reaming depth at the corresponding position does not meet the standard. The adjustable screw 102 is then locked in position by the limit structure, which helps the operator record and confirm the corresponding depth so that a second reaming at the corresponding depth can be performed later.

[0045] The device of this application is simple, portable, practical, easy to make and easy to operate; it has high inspection accuracy and small human error; it has high safety protection and reduces the risk of falling; it has a wide range of application scenarios, high efficiency of single-person operation and saves costs.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
