Shockproof bridge base and shockproof method thereof

Abstract

The invention discloses a shockproof bridge base and relates to the technical field of shock resistance of bridges. The shockproof bridge base includes a supporting base, a supporting plate is fixedlyconnected to the bottom of the supporting base, and movable rods are movably connected to both sides of the bottom of the supporting plate; a sliding block is movably connected to the bottom of eachmovable rod, a sliding board is slidingly connected to the bottom of each sliding block, the bottom of each sliding block penetrates through the corresponding sliding board and extends into the sliding board, and the side, extending into the corresponding sliding board, of each sliding block is slidingly connected to the bottom of the inner wall of the sliding board. According to the shockproof bridge base and a shockproof method thereof, a pushing rod positioned on one side of each sliding block is fixedly connected to the interior of the corresponding sliding board, vibration during runningof a vehicle and an earthquake is reduced, the stability and safety of a bridge surface are guaranteed, and the damping effect is improved; by fixedly connecting sleeves on both sides of the bottom ofthe supporting plate and between the opposite sides of vertical rods, multi-damping is achieved, the damping effect is better, the bridge surface is more stable, and the service life of the bridge isprolonged.

Description

technical field [0001] The invention relates to the technical field of anti-seismic bridges, in particular to an anti-seismic bridge base 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; the auxiliary...
