Anti-collision facility for bridge

Abstract

The invention relates to an anti-collision facility for a bridge. The anti-collision facility comprises a support frame and guard rings. The support frame comprises two first connecting plates and twofirst connecting rods, and the support frame is fixed to the outer side of a pier, so that the facility is fixed to the outer side of the pier, and passing ships can be effectively prevented from colliding with the pier. The first connecting plates are provided with first sliding grooves matched with the first connecting rods, and the first connecting rods movably penetrate through the first sliding grooves. The two ends, opposite to the corresponding first sliding groove, of each first connecting rod are provided with a first fixing ring and a second fixing ring respectively, and the first fixing rings, the second fixing rings and the first connecting rods are in threaded connection. Second connecting rods are arranged on the outer sides of the first connecting plates, first fixing plates are arranged on the outer sides of the second connecting rods, and the first fixing rings and the second fixing rings are adjusted so that the facility is able to be conveniently fixed to the periphery of the pier.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an anti-collision facility for bridges. Background technique [0002] Nowadays, with the continuous increase of the number of four cars, the traffic load is increasing. In order to solve the gradually increasing traffic load, more and more roads and bridges are being built, and the number of bridges is gradually increasing. When the boats in the river When sailing, when crossing the bridge, it is easy for ships and piers to collide with each other, which will affect the service life of the bridge. In the prior art, flexible baffles are usually used to prevent collisions of passing ships on the outside of the pier columns. Elastic cushioning can absorb part of the energy, but it is prone to greater wear and tear after working for a long time. In addition, cruise ships are dynamic, and the height of each hull is different, so the contact orientation on both sides of the...

[0002] Nowadays, with the continuous increase of the number of four cars, the traffic load is increasing. In order to solve the gradually increasing traffic load, more and more roads and bridges are being built, and the number of bridges is gradually increasing. When the boats in the river When sailing, when crossing the bridge, it is easy for ships and piers to collide with each other, which will affect the service life of the bridge. In the prior art, flexible baffles are usually used to prevent collisions of passing ships on the outside of the pier columns. Elastic cushioning can absorb part of the energy, but it is prone to greater wear and tear after working for a long time. In addition, cruise ships are dynamic, and the height of each hull is different, so the contact orientation on both sides of the pier is different, and the parts of the cruise ship are easy to be elastic Components are stuck and broken, especially when multiple cruise ships pass through both sides of the pier column at the same time, relying solely on a single flexible baffle has a weak anti-collision ability for the two ships, which is likely to cause damage to the baffle or the hull
