Novel bridge pier anti-collision device

Abstract

The invention discloses a novel bridge pier anti-collision device, and relates to the technical field of bridge piers. The device comprises a bridge pier, a steel bushing, a plurality of first fixingplates and a plurality of second fixing plates, a first damping layer is arranged between the bridge pier and the steel bushing, a plurality of first slotted holes are formed in the peripheral side face of the steel bushing, the second fixing plates slide along the inner walls of the first slotted holes, a second damping layer is fixedly arranged at the peripheral side face of the steel bushing, and the first fixing plates slide along the inner wall of the second damping layer. Due to cooperation of the second damping layer, a first spring, a second spring and a third spring, deceleration treatment is performed on a ship colliding with the bridge pier, most impact generated by ship collision can be absorbed, secondary deceleration treatment is performed on the ship colliding with the bridge pier by means of cooperation of the steel bushing and the first damping layer, and remaining impact energy generated by ship collision can be completely absorbed as much as possible, so that the safety of workers on the ship and the bridge pier is protected, and the collision damage of the bridge pier is smaller.

Description

technical field [0001] The invention belongs to the technical field of bridge piers, in particular to a novel bridge piers anti-collision device. Background technique [0002] The intermediate supporting structures of multi-span bridges are called piers. Bridge piers are divided into solid piers, column piers and bent piers. According to the plane shape, it can be divided into rectangular piers, pointed piers, round piers, etc. The materials of building bridge piers can be wood, stone, concrete, reinforced concrete, steel, etc. Bridge piers are generally made of concrete or rocks. It is characterized by making full use of the compressive properties of masonry materials and bearing The external force in the vertical direction and the horizontal direction has the advantages of firmness and durability, simple construction, convenient material acquisition, and steel saving. [0003] The anti-collision design of bridge piers in our country mainly considers the impact and wear ...

AI Technical Summary

Problems solved by technology

[0003] The anti-collision design of bridge piers in our country mainly considers the impact and wear on piers when a large area of ​​drift ice occurs, but less consideration is given to accidental phenomena such as ships hitting bridge piers, which makes bridge piers suffer from severe impacts. There is a phenomenon of fracture, which greatly affects the stability of the entire bridge, and causes a large loss, which seriously affects the transportation of traffic; at the same time, the damage of the hull hitting the pier is more serious, and it will cause a lot of casualties
