[0002] A bridge expansion joint refers to a joint set between two beam ends, between a beam end and an abutment, or at the hinge position of a bridge to meet the requirements of bridge deck deformation. It is required that the expansion joint can freely expand and contract in two directions parallel and perpendicular to the bridge axis, be firm and reliable, and the vehicle should drive smoothly without sudden jumps and noises when passing through; it should prevent rainwater, garbage, and soil from seeping in and blocking; installation, inspection, maintenance, and removal of dirt should be simple and convenient. At the location where the expansion joint is set, the railing and the bridge deck paving should be disconnected.
[0003] The function of a bridge expansion joint is to adjust the displacement and connection between the superstructures caused by vehicle loads and bridge building materials.
