Background technique

Ship collisions have been happening all over the world, and the frequency of ship collisions is much higher than we think. The casualties, property damage and environmental damage caused by the ship’s collision with the bridge were amazing. Many ships hit the bridge and lost tens of thousands of yuan. In addition, the casualties and losses are in the millions, tens of millions or even billions of dollars. A large number of indirect losses are even more difficult to calculate.

Many facts show that the occurrence of bridge accidents is mainly due to the damage of the lower structure of the bridge. Therefore, it is necessary to improve the anti-collision performance of the bridge pier. It can be divided into two aspects, namely active collision and passive collision. Active anti-collision is to improve the anti-collision ability of the pier itself through the design of the bridge structure. It is often necessary to design the bridge pier to be huge, neither economical nor beautiful, but also affect the navigation capacity of the channel. Passive anti-collision is through the installation of anti-collision protection system. Improve the anti-impact ability of the pier, because it is relatively flexible, it can be comprehensively compared according to the actual situation, it is a widely used anti-collision means.

It is difficult to repair after the damage. At the same time, the hull is vulnerable to damage during the collision. In addition, the steel is easy to rust in water all year round, and the maintenance cost is higher. High, in view of the many drawbacks of the current common anti-collision facilities, this patent intends to introduce the crashworthiness of the fiber reinforced composite structure into the field of bridge collision avoidance.
