Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tunnel crack depth measurement, in particular to a tunnel crack depth measurement device. Background Art
[0002] At present, the pavement of bridges in cities is formed by paving asphalt. Due to the effect of vehicle load and the influence of natural factors, pit-shaped cracks will appear on the asphalt pavement. Some cracks are shallow and will not have too much impact on the asphalt pavement, but some cracks are deep. If they are not repaired in time, the traffic on the bridge will cause deeper damage to the asphalt pavement and affect driving safety.
[0003] The existing Chinese patent publication number is: CN214460042U. A device for measuring the depth of cracks in highway bridges and tunnels, which relates to the technical field of road and bridge detection devices, solves the problem that auxiliary cleaning cannot be achieved through structural improvements; spraying and dust reduction cannot be achieved through synchronous linkage; finally, the existing device cannot achieve dust prevention at the socket through structural improvements after use. A device for measuring the depth of cracks in highway bridges and tunnels, including a vehicle body; a detection device is installed on the vehicle body, and a cleaning structure is also installed on the vehicle body, and a spraying structure is also installed on the vehicle body. Because the cleaning block is welded on the sliding rod, and the cleaning block is a triangular structure, and the cleaning block contacts the ground, the road can be cleaned when the vehicle body moves; secondly, because there are two elastic members, and the two elastic members are respectively sleeved on the two sliding rods, and the two elastic members together constitute the elastic pushing structure of the cleaning block, thereby ensuring the close contact between the cleaning block and the ground.
[0004] Although the above technical solution has a cleaning structure installed on the vehicle body, and a spraying structure is also installed on the vehicle body, which can clean the construction joints, the cleaning block is in close contact with the ground to achieve a better cleaning effect. The device detects the construction joints, and the cracks need to be filled after the detection, reducing the subsequent filling process. The detection and filling construction are carried out simultaneously to save manpower and construction time. Utility Model Content
