Steel composite material anti-collision facility

Abstract

The invention relates to a steel composite material anti-collision facility comprising an anti-collision ring and an energy consuming filler. The anti-collision ring is formed by connecting a plurality of sections head to tail and is in a runway shape, and the sections are connected through connecting flanges, are each in an annular column shape and are filled with the energy consuming filler. Energy consuming partition plates evenly partition the energy consuming filler, and inner reinforcing steel cylinders are attached to the inner walls of the sections. By adoption of the structure, compared with the prior art, from the perspective of the structure, the overall structure is high in flexible collision prevention and buffering energy absorption efficiency, high in strength, excellent incorrosion resistance, durability, collision resistance and fatigue resistance, high in cost performance, small in weight, convenient to transport, mount and replace, environmentally friendly and beautiful in appearance, and colors can achieve the warning effect; and non-metallic materials are adopted, and the anti-theft effect can be achieved.

Description

technical field [0001] The invention relates to a bridge pier anti-collision facility, in particular to a steel composite material anti-collision facility. Background technique [0002] With the development of my country's economy and society, my country's bridge construction has entered a stage of rapid development. According to statistics, there are more than 730,000 existing bridges in my country, with a total length of more than 40,000 kilometers. Bridges on navigable rivers account for about 10% of the total number of bridges. , the ship bridge accident that comes along with also more and more arouses the attention of all quarters. The problem of bridge ship collision prevention is gradually getting great attention from relevant shipping management, planning and design departments. [0003] For the existing anti-collision system, the position of the anti-collision device is generally fixed, but when setting up anti-collision facilities for bridges with large water level...

AI Technical Summary

Problems solved by technology

[0003] For the existing anti-collision system, the position of the anti-collision device is generally fixed, but when setting up anti-collision facilities for bridges with large water level changes, in order to meet the anti-collision requirements, the commonly used method is to increase the anti-collision facilities height, which not only increases the cost, but does not necessarily bring the desired effect; for the composite anti-collision ring that can change with the water level, it perfectly solves this problem, but in the high water level impact condition, the ship hits the bridge column, and the impact resistance of the bridge column is obviously weak, which may lead to bridge damage
