Bridge expansion joint: refers to the expansion joint to meet the requirements of bridge deck deformation, usually between the two beam ends, between the beam end and the abutment or the hinge position of the bridge. It is required that the expansion joints can be freely telescoped in two directions parallel and perpendicular to the axis of the bridge. It is firm and reliable. The vehicle should be smooth, no jump and noise when driving. It should prevent rainwater and garbage from seeping into the blockage; installation, inspection and maintenance It is easy and convenient to eliminate dirt. When setting the expansion joint, the railing and the deck pavement should be disconnected.


The role of bridge expansion joints is to adjust the displacement and coupling between the superstructure caused by vehicle loads and bridge building materials. Once the telescopic device of the skew bridge is damaged, it will seriously affect the speed, comfort and safety of the driving, and even cause traffic accidents.
