Description

Technical Field

[0001] The utility model relates to the technical field of bridge detection equipment, in particular to a bridge bottom surface crack detection device. Background Art

[0002] A bridge generally refers to a structure erected over rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, a bridge is also extended to a building that is erected across mountain streams, poor geology, or to meet other transportation needs to make passage more convenient. A bridge is generally composed of an upper structure, a lower structure, a support, and ancillary structures. The upper structure is also called the span structure, which is the main structure for crossing obstacles; the lower structure includes abutments, piers, and foundations; the support is a force transmission device installed at the supporting location of the span structure and the piers or abutments; the ancillary structures refer to the bridgehead slab, conical slope protection, revetment, diversion project, etc., and most of the damage to the bridge is caused by cracks in the bridge, so the bridge needs to be inspected regularly. At present, bridges are usually inspected manually. When inspecting them, the operators will shake and tremble because they are working at high altitudes, which will cause deviations in the test results and require multiple calibrations, thereby wasting a lot of time and energy of the operators.

[0003] To this end, we propose a bridge bottom surface crack detection device to solve the above problems. Utility Model Content
