Background
Along with the rapid development of the traffic construction of China, the scale and the quantity of bridges in China are continuously increased, the continuous innovation and breakthrough of the structural technology promote the rapid development of the bridge bearing field, meanwhile, the diseases of various bearings are gradually highlighted, and the problem is very sharp. Whether municipal works, road and bridge works, or subway works, railway works and the like are carried out, the bridge can generate diseases affecting operation safety such as support void, bolt damage, corner overrun, steel plate deformation and the like after many years of operation, the safety and reliability of the support directly relate to the safety and reliability of a bridge structure, once serious diseases occur, the bearing capacity and the service life of the bridge are seriously affected, collapse accidents are even caused, and the support diseases form great potential safety hazards to the operation of the bridge structure. Therefore, the bridge needs to be subjected to maintenance work such as repairing and reinforcing, support replacement, integral lifting and the like in the whole life cycle, and the process often needs to be subjected to jacking operation. In the jacking process, the jack, the steel plate and the bridge have friction force, so that the horizontal displacement of the bridge can be limited to a certain extent, and the stability and safety of the main body structure during construction are ensured.
At present, the existing supporting base plate for bridge jacking is mainly arranged for avoiding structural cracking caused by stress concentration, so that stable and safe jacking process is ensured. In the actual construction process, traffic is generally required to be blocked, the beam body is separated from the bridge pier, and after jacking is completed, the beam is dropped and the traffic is restored. For some important traffic routes and hinges, larger traffic pressure can be caused, daily travel, cargo transportation and the like are affected, and unnecessary losses are caused. If traffic is not blocked, vehicles are allowed to normally pass in the construction process, at the moment, the bridge main body is lifted, horizontal constraint of components such as original piers and the like on the bridge main body is lost, longitudinal horizontal force and displacement of vehicles running on the bridge to the bridge main body are transmitted to jacking equipment through friction force, at the moment, the jacking equipment needs to bear vertical force and horizontal force at the same time, and stability of the jacking equipment is greatly influenced, so that jacking safety is influenced.
Therefore, in some cases, in order to ensure the safety of the main body structures such as the bridge, it is necessary to ensure that a certain sliding occurs between the jacking device and the main body structures, and a combined backing plate capable of sliding in one direction should be selected according to the requirement of stress.
