Bridge expansion joint protection structure with elastic protection function

The utility model discloses a bridge expansion joint protection structure with an elastic force protection function. The bridge expansion joint protection structure aims at solving the technical problems that the inner wall of an existing bridge expansion joint is prone to being impacted and damaged when an expansion device is hung and installed, and the structural strength of the expansion joint is affected. The bridge expansion joint protection structure comprises bridge panels on the two sides of an expansion joint and grooves formed in the surfaces of the opposite sides of the bridge panels. According to the bridge expansion joint protection structure, an isolation layer is formed between the expansion device and the inner wall of the bridge expansion joint through the L-shaped elastic protection layer structure formed by the horizontal part polyfluortetraethylene plate and the vertical part polyfluortetraethylene plate, and when the expansion device collides with the inner wall of the expansion joint, pa
