Description

Technical Field

[0001] The present invention relates to the technical field of tunnel detection, and in particular to a knocking device for tunnel detection and a use method thereof. Background Art

[0002] The tapping device is a device for detecting the ground plane of the tunnel. When the current detection equipment is used to detect the tunnel, workers usually hold a small hammer to perform multiple tapping tests on the tunnel. However, it is difficult to control the tapping force and accuracy of manual tapping, which reduces the effect of tapping detection. In order to improve the accuracy of tapping detection, workers will use handheld iron balls to drop and tap from the same height for testing. However, when the iron ball falls from a high place, it is also difficult to ensure the position of the landing point, and different positions require different tapping forces, which increases the labor intensity of manual labor. For example, the prior art represented by the comparative document A tapping device for tunnel detection (publication number CN218331363 U) can adjust the height position of the tapping component and then adjust the tapping force through the set height adjustment component, and the height adjustment can be accurately controlled through the set pointer and scale. The set tapping component can perform multiple continuous tapping tests on the tunnel surface, which improves the efficiency of detection, thereby effectively solving the problems of the prior art. However, its structure still needs to be improved, as follows: In this scheme, when the detection equipment detects the tunnel ground plane, the height position of the knocking component can be adjusted through the set height adjustment component to adjust the knocking force, and the height adjustment can be accurately controlled through the set pointer and scale, and the set knocking component can perform multiple continuous knocking tests on the tunnel surface. In this scheme, only a small hammer can be driven to knock on the road surface during detection, and after one knock, the device needs to be pushed to the next position for detection, which makes the device more troublesome to use. At the same time, when encountering a softer road surface, the device will sink, which will cause the measured data to be not very accurate. At the same time, the knocking component and the height adjustment component need to move at the same time to detect the data during detection. Therefore, the data is not very convenient for later analysis. In order to be able to detect the tunnel ground plane well, a knocking device for tunnel detection is needed to improve the above problems. Summary of the invention

[0003] In order to solve the problem that only a small hammer can be driven to knock on the road surface during detection, and the device needs to be pushed to the next position for detection after knocking once, which makes the device more troublesome to use, and when encountering a soft road surface, the device will sink, which will cause the measured data to be not very accurate.
