Anti-collision device for independent float-type bridge pier

Abstract

The invention discloses an anti-collision device for an independent float-type bridge pier, belonging to the technical field of bridge anticollision. The anti-collision device independent from a protected bridge pier is composed of a fixed pier, a float-type anti-collision body and a support guidepost, wherein, the fixed pier arranged on a bank is fixedly connected with a protecting slope of the bank into a whole; the float-type anti-collision body is arranged at one side of the center of a river of the protected bridge pier, and forms dynamic matching connection with the support guidepost; the support guidepost is connected with or fixedly connected with the fixed pier; the float-type anti-collision body which can float up and down along the change of water level is separated from the protected bridge pier; and the clearance which can satisfy that the device can move up and down between the highest water level and the lowest water level is reserved. The device provided by the invention has a reasonable design and simple structure, can ensure that a bridge and a ship can not be collided to be damaged, is easy to overhaul and maintain, and has long service life.

Description

technical field [0001] The invention belongs to the technical field of bridge anti-collision, and in particular relates to an anti-collision device mainly used for bridge piers near banks on narrow river courses between mountains or bridge piers near shore non-navigable holes on special river sections. Background technique [0002] At present, most bridge piers in navigable rivers are not equipped with anti-collision devices. They only try to avoid making the piers in navigable waters or restrict navigable ships, and even improve the anti-collision ability of the piers themselves to prevent collision damage. These methods place additional constraints on the design of navigable vessels and bridges, and there is still a risk of damage to the piers in the event of a collision if the constraints fail. In the prior art, only a small part of the bridges have been protected against collisions, but in these technologies, only the piers in the navigable waters are protected against c...

Problems solved by technology

These methods place additional constraints on the design of navigable vessels and bridges, and there is still a risk of damage to the piers in the event of a collision in which the constraints fail

In the prior art, only a small part of the bridges have been protected against collisions, but in these technologies, only the piers in the navigable waters are protected against collisions, and no one has considered to protect the bridge piers near the shore or the bridges on the narrow river between the mountains. Anti-collision protection of near-shore non-navigable piers on special river sections

Moreover, sometimes such special near-shore piers or bridges have poor anti-collision ability, large water level drop, and water depth, which makes anti-collision protection more difficult and the situation is more complicated.
