Background
With the continuous development of society and the rapid development of economy in China, bridges are also unprecedentedly developed as the fate of traffic. A bridge expansion joint is defined as an expansion joint between two beam ends, between a beam end and an abutment, or at a hinge joint of a bridge, in order to meet the requirement of deformation of a bridge deck. The expansion joint is required to be freely telescopic in two directions parallel to and perpendicular to the axis of the bridge, and the expansion joint is firm and reliable, and when a vehicle runs, the vehicle is smooth and free of sudden jump and noise; the rainwater and garbage soil can be prevented from infiltration and blocking; the installation, the inspection, the maintenance and the dirt elimination are all simple and convenient. Once the bridge expansion joint is damaged, the speed, comfort and safety of driving are seriously influenced, and even driving safety accidents are caused.
The existing bridge expansion joint such as RBKF80 type expansion joint is complex in structure and construction, and comprises the steps of firstly arranging multidirectional displacement hinges on the beam body structure surfaces on two sides of the expansion amount of a bridge, then installing a water stop structure in the expansion joint, then pouring C50 steel fiber concrete in a reserved groove on the beam body structure, covering a joint spanning plate on the expansion joint, leveling and finally curing by using concrete. In addition, the steel plate structure can cause uncomfortable driving and easily generate vehicle jumping in the driving process. After the expansion joint structure is used for a period of time, the vehicle can generate larger jolt and vibration sound due to impact when passing, and the long-time impact can cause the separation between the expansion joint member and the bridge girder body structure, so that the bonding strength between the expansion joint member and the bridge girder body structure is seriously reduced.
