[0002] Channel refers to the ship channel that is stipulated or set for ship navigation in river, lake, sea and other water areas. In recent years, with the increasing acceleration of national transportation infrastructure construction, the number of bridges crossing navigable waters is increasing.

[0003] At present, the anti-collision design of the bridge under construction is divided into active early warning and passive anti-collision. The active early warning equipment includes simple warning devices such as warning signs, bridge and culvert signs and navigation clearance display screens, or uses multiple sensors, communication systems and data analysis algorithms to realize high-precision ship identification and tracking. The system can realize accurate monitoring and early warning of ship position, speed, height and other dimensions. This can only warn and needs to be adjusted by the ship itself. If the ship loses control, there is still danger.

[0004] Passive anti-collision facilities generally wrap the bridge pier column outside with a circular anti-collision facility. After the ship collides, the anti-collision facility absorbs the impact force generated to protect the bridge. However, this scheme still causes the bridge to bear a part of the impact force, which affects the main body of the bridge and has certain safety risks. It cannot withstand multiple collisions and has limitations on bridge protection. CONTENT OF THE UTILITY MODEL
