Description

Technical Field

[0001] The utility model relates to the technical field of highway anti-collision, in particular to an anti-collision device for a highway bridge. Background Art

[0002] Highway bridges are an important part of the highway transportation network. They are mainly used to cross obstacles such as rivers, valleys, railways or other roads to ensure the continuity and smoothness of the highway. There are many types of highway bridges, which can be divided into beam bridges, arch bridges, suspension bridges, cable-stayed bridges, truss bridges, rigid frame bridges, etc. according to their structural form.

[0003] In order to ensure the normal use of highway bridges, it is often necessary to maintain the bridges regularly. During the maintenance process, it is often necessary to carry out protective operations on the maintenance sections. Generally, some large anti-collision cylinders or anti-collision guardrails are simply placed. However, this type of anti-collision equipment generally has simple anti-collision functions. However, for some high-speed vehicles, the protective effect of this type of anti-collision guardrail is relatively low, which can easily cause high-speed vehicles to crash into the maintenance site, causing safety accidents and damage to the bridge sections.
