Vibration-isolating bridge

Abstract

The invention discloses a vibration-isolating bridge, which includes a base, two piers and two first clamping blocks are arranged above the base, Between that two bridge pier are two said first card blocks, supporting blocks are arranged inside the two piers, A shock absorber is arranged above the two supporting blocks, two fixing blocks and a first damping spring are arranged inside the two shockabsorbers, two first damping springs are respectively positioned between two fixed blocks, A card slot is provided, first block, the bayonet and the second bayonet, A card slot is arranged on the first card block and the second card block, The inside of the clamping slot is clamped with the clamping column. When the pier cracks need to be repaired or replaced, the operator can clamp the clampingcolumn in the clamping slot through the external equipment, thus playing the role of strengthening the bridge, preventing the bridge from collapsing accidentally, and solving the problem that the bridge collapse will cause personal safety to the operator when the operator changes the pier.

Description

technical field [0001] The invention belongs to the technical field of bridges, and in particular relates to a vibration-isolation bridge. 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. Bridges are generally composed of superstructure, substructure, supports and auxiliary 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 force transmission device installed at the support of the span structure and the bridge pier or bridge abutment, and the auxiliary structures refer to the bridge head board, conical slope protection, bank revetment,...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a vibration-isolation bridge to solve the problem that the vibration isolation effect of the bridge proposed in the above-mentioned background technology is not good, and after cracks appear in the bridge pier, the problem that the bridge collapses easily when the bridge pier is replaced
