Abstract

The invention relates to a shock absorption counterweight system for a bridge and a working method thereof. The shock absorption counterweight system comprises a plurality of concave counterweight bases fixed to a box girder bottom plate of the bridge in the bridge direction and the transverse bridge direction, wherein counterweight structures are mounted on the counterweight bases, the counterweight structures comprise cubic counterweight blocks and a plurality of concave counterweight blocks distributed from top to bottom, the counterweight bases and the concave counterweight blocks are allprovided with grooves, the upper counterweight blocks are placed in the grooves of the counterweight blocks below the upper counterweight blocks, buffer pieces are arranged on the side walls of the grooves, elastic elements are arranged between the bottommost concave counterweight blocks and the counterweight bases, elastic elements are arranged between the adjacent concave counterweight blocks, and elastic elements are arranged between the upmost cubic counterweight blocks and concave counterweight blocks below the upmost cubic counterweight blocks. The shock absorption counterweight system has simple structure and convenient construction, and effectively reduces the seismic requirements of a bridge structure.

Description

technical field

[0001] The invention relates to the technical field of bridge construction, in particular to a shock-absorbing counterweight system for bridges and a working method thereof. Background technique

[0002] In recent years, earthquakes have occurred frequently all over the world, causing great loss of life and property to humans in the disaster-stricken areas. A large number of bridge structures have been severely damaged in earthquakes, causing serious secondary disasters. In order to improve the seismic performance of bridge structures, seismic isolation technology has gradually been widely used in the design of bridge structures. At present, shock-absorbing and isolating bearings, dampers and other devices are mainly used in bridge structures for shock-absorbing and isolating design. higher. Contents of the invention

[0003] The purpose of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of damping counte...
