Description

A floating anti-ship collision energy consumption device

technical field

The invention relates to a bridge anti-ship collision device, in particular to a suspended type anti-ship collision energy consumption device.

Background technique

Since the 1980s, my country has built more and more bridges in wide waters and open seas and deep waters, which have played an indispensable role in the rapid development of highways and railways and the growth of the national economy. However, these bridge structures located in navigable deep-water waters are artificially constructed obstacles for water transport ships, and there is a risk of ship collision, and this risk exists objectively throughout the entire life of the structure. In the event of a ship collision accident, the bridge structure may need to bear a huge lateral impact load, and the bridge in the design navigable waters must give full consideration to the ship collision problem. Otherwise, it may lead to serious damage to the bridge structure, or even complete collapse, resulting in huge economic losses, casualties and negative social impact.

Bridge pier anti-collision devices can be roughly divided into two categories: independent anti-collision structures suitable for high-energy collisions, such as pile-supported anti-collision structures, artificial islands, etc.; attached anti-collision structures suitable for medium and low energy collisions, such as steel structures Fender protection system, etc. At present, the most widely used anti-ship collision device in China is the steel structure fender with obvious advantages in terms of anti-collision range, reduction of ship damage, economy, etc., but the steel itself is easy to corrode, making the steel structure fender in bridge service The maintenance cost remains high within the time limit. At this time, it is necessary to develop a new type of anti-collision equipment that takes into account the advantages of steel structure fenders and has good durability.

Ultra-high-performance concrete is a high-performance material that has recently emerged in the field of civil engineering. In view of its high strength, good toughness and excellent durability, a durable floating anti-ship that can withstand medium-energy impacts and micro-damages has been developed and designed. It is possible to hit energy-consuming devices.
