Description
Technical Field
The utility model relates to a bridge shockproof technical field especially relates to a multiple buffering bridge antidetonation device that resets.
Background
The development trend of China is as follows: the highway system in China is continuously perfected, and in order to deal with special environment and protect the environment of roads along the road, part of land resources are saved, the utilization rate of space is improved, and bridges become necessary choices for development. In addition, as part of China is located in Pacific volcanic seismic zones and Eurasia seismic zones, which are high-rise earthquake areas, once an earthquake occurs, the bridge is damaged, so that not only is huge economic loss caused, but also traffic paralysis caused by road breakage is caused, and larger indirect loss is caused. Based on the situation, research on bridge earthquake resistance, shock absorption technology and devices is very necessary, and the following main damages of the bridge under the earthquake are found through observation and research on the bridge subjected to the earthquake: the bridge produces great relative displacement with the movable support and leads to the support to damage, produces great displacement between the roof beam body and the pier and arouses the bridge to take place to damage along the bridge or the roof beam that falls of cross bridge to, the bridge body that the expansion joint both ends that leads to having the expansion joint takes place the damage of the bridge main part that direct collision leads to and passes to the pier bottom owing to the collision with the effect of collision force, causes the damage of bridge bottom also can lead to the expansion of expansion joint simultaneously.

At present, the mainstream design scheme for bridge earthquake resistance is that two reinforced concrete stoppers are arranged in the direction of a transverse bridge to limit the transverse bridge displacement of the bridge in the earthquake, but the design ignores the damage of a support caused by the relative displacement of the bridge and a movable support, the rigid collision of the bridge and the reinforced concrete stoppers causes the transmission of collision force to a pier to cause the damage of the pier and the like, the displacement and force generated by the earthquake on the bridge are complicated and changeable, and only one condition is considered, so that no method is provided for ensuring the relative integrity of a bridge main body in the earthquake. Therefore need design one kind and can follow the horizontal bridge to, it is vertical, along the bridge to three-way stop device, and the rigid collision that will lead to the bridge damage turns into the elastoplasticity collision that can the energy loss, thereby it damages to solve the support that bridge and movable support produced great relative displacement and lead to, thereby bridge main body and dog take place the bridge pier that the rigid collision leads to and produce the irreparable destruction and guarantee that the harm that the bridge received in the earthquake reduces, let the bridge still can guarantee certain transport capacity after receiving the earthquake, reduce the traffic damage that the earthquake caused, reduce the indirect damage that leads to because of the traffic is inconvenient.
