Problems solved by technology

[0002] With the development of social economy, in bridge construction, in order to meet the deformation requirements of the bridge deck, expansion joints are usually set between the two girder ends, between the girder end and the abutment, or at the hinge position of the bridge. The displacement and connection between the superstructure caused by the vehicle load and bridge building materials, and the quality and safety monitoring of the expansion joints are particularly important. If the expansion joint spacing is too small, it will cause deformation due to temperature stress, and if it is too large, it will lead to uneven road surface. As a result, there are loud noises and "jumping" phenomena during the driving process of the car, which poses a greater safety hazard
