Anti-seismic base used for bridge and anti-seismic method of anti-seismic base

Abstract

The invention discloses an anti-seismic base used for a bridge. The anti-seismic base used for the bridge comprises a supporting seat. A supporting board is fixedly connected to the bottom of the supporting seat. The two sides at the bottom of the supporting board are movably connected with movable rods. The bottom ends of the movable rods are movably connected with sliding blocks. The bottoms ofthe sliding blocks are in sliding connection with a sliding board. The bottoms of the sliding blocks penetrate through the sliding board and extend into the sliding board. The sides, extending into the sliding board, of the sliding blocks are in sliding connection with the bottom of the inner wall of the sliding board. The invention relates to the technical field of bridge seismic resistance. By the adoption of the anti-seismic base used for the bridge and an anti-seismic method of the anti-seismic base, a push rod is fixedly connected with the side, located in the sliding board, of each sliding block, shakes generated in the vehicle traveling process and an earthquake are reduced, the stability and safety of a bridge floor are guaranteed, an anti-seismic effect is improved, sleeves are fixedly connected to the positions, located on the opposite sides of vertical rods, on the two sides of the bottom of the supporting board, multiple seismic reduction is achieved, an anti-seismic effectis better, the bridge floor is more stable, and the service life of the bridge is prolonged.

Description

technical field [0001] The invention relates to the field of bridge anti-seismic technology, in particular to an anti-seismic foundation for a bridge and an anti-seismic method thereof. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountains, poor geology, or meet other traffic needs to make traffic more convenient. Buildings and bridges are generally composed of superstructure, substructure, supports and subsidiary structures. The superstructure is also called bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; the supports are bridge spans The force transmission device installed at the supporting place between the structure and the bridge pier or bridge abutment; t...
