[0002] Bridge expansion joints are important connecting components of bridge structures. They directly bear the impact of wheel loads and are exposed to the natural environment for a long time. Bridge expansion joints are the most easily damaged and difficult to repair structures. Bridge expansion joints include simply supported structures, cantilever structures and semi-cantilever structures.

[0003] The existing boltless impact-resistant comb plate expansion device eliminates the bolt connection of the comb plate by improving the comb plate structure, thereby overcoming the problem that the bolts in the expansion joint of the traditional comb plate are easy to loosen, fall off or be damaged. A dustproof plate is set to prevent the drainage pipe from being blocked. However, this method requires a drainage pipe to be set on the dustproof plate. Mud and sand are easily accumulated on the dustproof plate, thereby blocking the drainage pipe, which makes it impossible for the drainage pipe to discharge water and is unable to handle the debris on the dustproof plate.
