Anti-Collision Device Structure Research on Reservoir Arch Bridge

The construction of reservoir is beneficial to improving channel conditions, but at the same time, it also increases the possibility of ship-bridge collision, especially for arch bridge, the navigable clearance of which reduces. Once the collision happens, it will lead to a serious accident, therefore, the construction of anti-collision device is particularly important. “Arc Water Lifting Anti-collision Device” is designed to protect reservoir arch bridge from being hit by ships, which is mainly composed of three parts, that’s collision belt, buoy and oriented well, and it can lift freely with the water level changing. In this paper, this device is applied in Wanzhou Yangtze River Highway Bridge, and it is proved that this new device can meet the security requirements of ship, bridge, and itself when the collision occurs.
