Description

Technical Field

[0001] The utility model relates to the technical field of bridge detection, in particular to a bridge expansion joint detection device. Background Art

[0002] Bridge expansion joint: refers to the expansion joint usually set between the two beam ends, between the beam end and the abutment, or at the hinged position of the bridge to meet the requirements of bridge deck deformation. The expansion joint is required to be able to freely expand and contract in both directions parallel and perpendicular to the bridge axis, be firm and reliable, and be smooth without sudden jumps and noise when vehicles pass through; it must be able to prevent rainwater and garbage and soil from infiltrating and blocking; installation, inspection, maintenance, and removal of dirt must be simple and convenient. At the expansion joint, the railing and the bridge deck pavement must be disconnected.

[0003] The function of bridge expansion joints is to adjust the displacement and connection between the superstructure caused by vehicle loads and bridge construction materials. Once the expansion joints of skew bridges are damaged, it will seriously affect the speed, comfort and safety of driving, and even cause driving safety accidents.

[0004] Because bridge expansion joints play a vital role in the use of bridges, they need to be inspected regularly to ensure their performance. Conventional bridge expansion joint inspection schemes mainly measure the height difference between the two sides of the expansion joints and the width of the expansion joints manually with a ruler. Due to the influence of human factors, the position of the ruler cannot be fixed, and the measurement accuracy is prone to errors, which affects the inspection results.
