Municipal bridge anti-collision device and construction method thereof

Abstract

The invention discloses a municipal bridge anti-collision device and a construction method thereof. The anti-collision device is formed by splicing anti-collision single bodies, each anti-collision single body comprises two first anti-collision assemblies which are symmetrically arranged, the first anti-collision assemblies are arranged on the two sides of a bridge body, and every two opposite first anti-collision assemblies are fixedly connected through a connecting rod; and second anti-collision assemblies are arranged on the outer side surfaces of the first anti-collision assemblies, and every two adjacent first anti-collision assemblies are fixedly connected through a limiting assembly and a reinforcing assembly. The method comprises the steps of bridge body cleaning, first anti-collision assembly machining, second anti-collision assembly installation, reinforcing assembly machining and anti-collision single body installation. By means of the design of the anti-collision single bodies, splicing installation construction of the anti-collision device is facilitated, when local anti-collision single bodies are damaged by collision, only the corresponding anti-collision single bodies need to be replaced, the construction method is simple in step, construction installation of the anti-collision device is facilitated, the anti-collision strength is greatly improved, and damage to a bridge body is avoided.

Description

technical field [0001] The invention relates to a municipal bridge anti-collision device and a construction method thereof. Background technique [0002] With the rapid development of transportation, bridges have been built in large numbers due to their characteristics of crossing rivers, facilitating cross-strait connections, and shortening highway mileage. [0003] However, the bridges in the prior art often ignore the protection of the guardrails on both sides of the bridge body because they focus on the protection of the bridge body and piers. Generally, vehicles collide with the guardrails, which are easy to break the guardrails, and cause the vehicles to fall into the water or the bottom surface at the same time, causing vehicles and The secondary injury of passengers greatly increases the difficulty of rescue and increases the maintenance cost. Contents of the invention [0004] The purpose of the present invention is to provide a municipal bridge anti-collision de...
