A kind of municipal bridge anti-collision device and construction method thereof

Abstract

The invention discloses an anti-collision device for municipal bridges and a construction method thereof. The anti-collision device is formed by splicing together an anti-collision unit. The anti-collision unit includes two sets of symmetrically arranged first anti-collision assemblies. On both sides of the bridge body, the two opposite first anti-collision components are fixedly connected by connecting rods. The outer surface of the first anti-collision component is provided with a second anti-collision component, and the two adjacent first anti-collision components on the left and right are The components are fixedly connected through the limit component and the reinforcement component. The method includes: cleaning the bridge body, processing the first anti-collision component, installing the second anti-collision component, processing the reinforcing component, and installing the anti-collision unit. Through the design of the anti-collision unit, the present invention not only facilitates the splicing and installation construction of the anti-collision device, but also only needs to replace the corresponding anti-collision unit when the local anti-collision unit is damaged by the collision. Simple, not only conducive to the construction and installation of the anti-collision device, but also greatly improves the anti-collision strength and avoids damage to the bridge body.

Description

technical field [0001] The invention relates to an anti-collision device for municipal bridges 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 communication, and shortening road mileage. [0003] However, the bridges in the prior art tend to ignore the protection of the guardrails on both sides of the bridge body due to the emphasis on the protection of the bridge body and the piers. Generally, the vehicle collides with the guardrail, which is easy to break the guardrail, and at the same time causes the vehicle to fall into the water or the bottom surface, causing the vehicle and the The secondary injury of passengers greatly increases the difficulty of rescue and increases maintenance costs. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a technical scheme o...
