Description
Technical Field
[0001] The utility model relates to the technical field of crack detection, in particular to a bridge bottom surface crack detection device. Background Art
[0002] More than 90% of the damage to concrete bridges is caused by cracks. Some cracks continue to generate and expand new cracks under the influence of usage loads or external physical and chemical factors, forming through cracks and deep cracks. Cracks larger than 0.20 to 0.30 mm will directly destroy the integrity of the structure, causing concrete carbonization, peeling of the protective layer, and corrosion of the steel bars, forming mechanical discontinuities inside the bridge, greatly reducing the bearing capacity of the bridge. In severe cases, even collapse accidents may occur, endangering the normal use of the bridge structure.
[0003] The traditional method of detecting bridge cracks is mainly manual detection. When detecting cracks on the bottom surface of the bridge, the staff needs to go down to the bottom surface of the bridge in person, which is very dangerous and inconvenient to conduct a comprehensive inspection of the bottom surface of the bridge. At the same time, when the weather is relatively bad, it will affect the detection efficiency. Therefore, we proposed a bridge bottom surface crack detection device to solve the above problems.
