[0002] Bridge construction at home and abroad is an important part of the development of road traffic. However, with the development of the multifunctionality of bridges and roads, factors such as motorcycles, non-motor vehicles, and pedestrians on bridges have gradually been included in the important aspects of bridge design. The existing bridge sidewalk expansion joint devices are mainly modular and comb-tooth types. However, the comb-tooth plate expansion joint has great defects in the application of sidewalks. When using the comb-tooth plate expansion joint, it is easy for motorcycle and bicycle wheels to get stuck in the gap between the teeth, and pedestrians may be tripped by the teeth. Pedestrians' belongings may fall under the bridge through the gap between the comb teeth, causing falling objects from high altitude. In addition, the use of the comb-tooth plate on the sidewalk will also affect the appearance of the bridge deck. The rubber water stop between the beams of the modular expansion device may age and break, and it is possible that the objects dropped by pedestrians while walking will fall under the bridge through the aging and broken gaps.
