Description

Technical Field

[0001] This invention relates to the field of tunnel inspection, specifically to a tunnel settlement detection device and its detection method. Background Technology

[0002] With societal development, tunneling for railway construction has become a means to improve transportation convenience. However, tunnel walls may suffer from cracks, holes, fissures, and water seepage, directly impacting tunnel lifespan and traffic safety. Therefore, inspecting railway tunnels is a crucial measure to ensure traffic safety. Currently, the mainstream tunnel inspection technology utilizes vehicle-mounted ground-penetrating radar (GPR). After the GPR extends to the target location, a moving vehicle then actuates the radar to conduct its detection.

[0003] Currently, common testing equipment can only detect flat-roofed tunnels, not domed tunnels, which reduces the applicability of settlement testing equipment. At the same time, existing tunnel settlement testing equipment lacks protective components, which can lead to damage during use or transportation, making it difficult for staff to use and reducing the efficiency of tunnel settlement testing.

[0016] A detection method for tunnel settlement detection equipment, comprising the following steps:

[0017] S1. Workers move the mobile vehicle, along with the components and leveling instrument above it, by pushing the handrail, so that it moves to the reference point of the tunnel.

[0018] S2. By setting the height adjustment component, move the height of the leveling instrument to be parallel to the tunnel arch, then mark the positions to be inspected and record them.

[0019] S3. Periodically return to the tunnel, readjust the height of the leveling instrument, and then measure the vertical height of the surface. At the same time, the angle of the leveling instrument can be adjusted by setting the angle adjustment component, and it can be slid along the inner top wall of the tunnel to measure more locations.

[0021] The present invention also discloses a method employing the above method, comprising the following steps:

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. With the addition of height adjustment and protective components, workers can use the height adjustment component to move the leveling instrument upwards to the top of the tunnel arch. This facilitates settlement detection of the tunnel using the leveling instrument. During the upward movement, the protective frames on both sides automatically open, allowing the frames to rotate from a vertical to a horizontal position without obstructing the movement of the leveling instrument. When retracted, the protective frames on both sides automatically close to protect the leveling instrument inside. When not in use, the protective frames protect the leveling instrument, thus extending its service life during transportation and improving the efficiency of settlement detection in the tunnel.

[0024] 2. By setting the angle adjustment component, the electric push rod can be extended or retracted, so that the adjustment rod moves back and forth around the movable seat as the center. This allows the level detector on the upper surface to move back and forth close to the upper surface of the tunnel dome, effectively detecting settlement. This improves the detection range of the device and the detection efficiency of the staff.

[0025] 3. By setting up telescopic columns, protective springs, arc-shaped plates, and auxiliary rollers, the device moves along with the arc-shaped plates and auxiliary rollers during its movement. The auxiliary rollers move along the inner top wall of the tunnel, and the arc-shaped plates provide some protection for the level detector. At the same time, when it encounters obstacles such as lighting devices or crossbeams during movement, it causes the arc-shaped plates and auxiliary rollers to retract downwards and compress the internal protective springs, thus preventing them from affecting the overall inspection work.

A detection method for a tunnel settlement detection apparatus, characterized by, The lower surface of the moving vehicle (1) is provided with universal wheels (6) at four corners, one side of the upper surface of the moving vehicle (1) is provided with a pushing handrail (7), one side of the upper surface of the moving vehicle (1) is provided with a supporting frame, the inside of the supporting frame is rotatably connected with a mounting rod through a damping rotating shaft, and one end of the mounting rod is fixedly provided with an illuminating lamp (8). The tunnel settlement detection equipment comprises the following steps: S1, the staff moves the moving vehicle (1) and the components and the horizontal detector (4) above the moving vehicle (1) by pushing the pushing handrail (7), so that the moving vehicle (1) moves to the reference point of the tunnel. S2, through the height adjustment assembly (2) of setting, the height of horizontal detector (4) to the vault of the tunnel parallel, then mark the position of the need to be detected, and make a good record; S3, back to the tunnel regularly, re-adjust the height of the horizontal detector (4), then measure the vertical height of the surface, at the same time, can adjust the angle of the horizontal detector (4) through the setting of the angle adjustment assembly (3), slide on the inner top wall of the tunnel, measure more positions; S4, if the vertical height of a point is found to be decreased, it means that the settlement of the area where the point is located occurs, the measurement results are recorded and reported.
