Anti-collision device for floating pier with steel-bamboo sandwich board

Abstract

The invention discloses a steel-bamboo sandwich board floating type pier collision prevention device which comprises a frame body surrounding a pier. The two sides of the frame body are provided witha first high-alkali-resistance glass fiber cloth layer and a second high-alkali-resistance glass fiber cloth layer which are oppositely arranged. The first high-alkali-resistance glass fiber cloth layer or the second high-alkali-resistance glass fiber cloth layer is arranged opposite to the pier. The frame body is internally filled with light filler which is at least used for enabling the pier collision prevention device to float in water. A metal damper is further arranged in the frame body. As the density of the steel-bamboo sandwich board floating type pier collision prevention device is far smaller than the density of seawater, the pier collision prevention device can float on the sea surface, cutting is easy, site splicing can be achieved, the device can be assembled to be in the required structural form flexibly according to the size and shape of the pier, and local replacement and maintenance can also be achieved when the device is damaged later.

Description

technical field [0001] The invention particularly relates to a steel-bamboo sandwich board floating bridge pier anti-collision device, which belongs to the technical field of anti-collision bridge piers. Background technique [0002] There are many straits and rivers in our country. With the continuous growth of economic strength and national travel needs, a large number of new bridges across rivers, rivers and even seas have been built. They are gradually moving from a bridge country to a bridge power. However, the bridges face the risk of ship collision. It is also becoming more and more serious. With the improvement of my country's shipbuilding technology, the tonnage and size of ships are gradually increasing, and the probability and consequences of ships hitting bridges are also increasing. Such accidents can cause ships and If the bridge is damaged, it will cause serious consequences of shipwreck and bridge collapse. Therefore, it is necessary to install anti-collision ...

AI Technical Summary

Problems solved by technology

[0003] Traditional anti-collision protection devices include concrete boxes and steel sleeve boxes, etc. Although these anti-collision devices can alleviate impacts to a certain extent and protect bridge piers and ships, most of them have limitations or poor corrosion resistance. Either it is heavy, difficult to hoist, and does not have floating performance, or the "three highs" of high cost, high maintenance cost, and high maintenance cost
