Description

Technical Field

[0001] This utility model belongs to the field of anti-collision technology for long-span arch bridges, and more specifically, it relates to an all-round bridge anti-collision device. Background Technology

[0002] Long-span arch bridges typically span a waterway in a single span. Collision protection devices are installed near the arch abutments. Due to the large transverse dimensions of the arch abutments, the specifications of the collision protection devices also increase, significantly raising their cost. To save on project investment, collision protection piers are usually installed only on one side (upstream or downstream) near the arch abutments to resist the impact of oncoming ships.

[0003] However, actual ship collisions can occur from all directions. In such cases, installing anti-collision piers on only one side would render them ineffective, leaving the arch directly exposed to the potential risk of ship collisions. Therefore, there is an urgent need for a comprehensive bridge anti-collision device to address these issues. Utility Model Content
