Description

Technical Field

[0001] The utility model relates to the technical field of bridge maintenance, in particular to a bridge crack repair glue thickness detection device. Background Art

[0002] For a long time, due to the influence of the external environment and the aging of the material itself, small cracks often appear on the surface of bridge concrete. If these cracks are not repaired in time, they will lead to further expansion and spread, seriously affecting the structural safety and service life of the bridge.

[0003] Bridge concrete crack repair glue has high adhesion and permeability, can effectively penetrate into the cracks on the concrete surface, and form a good bond with the concrete. It has high compressive strength and tensile strength, can effectively enhance the structural strength of the repaired area, and improve the bearing capacity of the bridge. It is also weather-resistant and chemical-resistant, can maintain the repair effect for a long time and stably under various harsh environmental conditions, can quickly repair cracks, and shorten the construction period. The coating thickness of the repair glue affects the repair effect of the cracks. Therefore, after the construction is completed, the coating thickness of the repair glue needs to be tested. At present, the main measurement is a ruler. The end of the ruler is against the bridge body, and the ruler is close to the edge of the repair glue for measurement. Since the thickness of the repair glue is relatively small, it is difficult to read the reading during measurement. In addition, the ruler is prone to tilt during measurement, resulting in large errors in the measurement results. Utility Model Content
