Bridge column anti-collision protection device

Abstract

The invention provides a bridge column anti-collision protection device which comprises a bridge and pier columns. The outer sides of the pier columns are sleeved with bearings, and the bearings are tightly attached to the pier columns. The outer rings of the bearings are riveted to the inner sides of protective layers, outward extending antennas are additionally arranged on the protective layers,the antennas can surround the protective layers by a circle or are arranged in a semi-circular shape along the portions, facing a navigation channel, of the protective layers, and the protective layers and the antennas rotate along with the outer rings of the bearings when the pier columns collide with a ship. According to the device, the rotary structures of the bearings are utilized, the extending antennas are additionally arranged on the protective layers arranged on the outer side of the device, the acting force of transverse rotation during ship collision is increased, and therefore, anunloading function is achieved, the pier columns and the bridges are protected to the maximum extent, and meanwhile passing ships and personnel are protected against damage.

Description

technical field [0001] The invention relates to the technical field of bridge protection, in particular to a bridge column anti-collision protection device. Background technique [0002] With the increase of the number of bridges, the increase of ship size and the increase of ship speed, the risk of bridge encountering ship collision gradually increases. [0003] There are three factors that cause a ship to collide with a bridge: one is human factors, including work negligence, mismanagement, insufficient technical ability, and errors in personnel cooperation; Normal steering command work, etc.; the third is the natural environment, including changes in channel parameters, weather, floods, bridge area channel environment and other natural factors. Considering from the point of view of bridge self-protection, a protective layer or some special materials will be used to protect the bridge, but the effect is often unsatisfactory. There is no suitable method to protect the brid...

AI Technical Summary

Problems solved by technology

Considering from the point of view of bridge self-protection, a protective layer or some special materials will be used to protect the bridge, but the effect is often unsatisfactory. There is no suitable method to protect the bridge. At the same time, the current protection methods are mainly in the The lower structure of the pier is equipped with flexible anti-collision. Due to the difference in ship shape and collision pressure, when the collision force between the upper structure of the pier and the ship is greater than the flexible anti-collision force, it basically does not play a protective role.
