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, a small number of bridges have received anti-collision protection, but in these technologies, only simple anti-collision protection is provided for bridge piers in navigable waters. Anti-collision protection of near-shore non-navigable piers on special river sections
Moreover, the protection of this special near-shore pier is more difficult and the situation is more complicated

Embodiment Construction

[0015] The specific implementation manners and related technical problems of the present invention will be further described in detail below in conjunction with the accompanying drawings. as attached figure 1 Shown, be the combination structure of the present invention's device and protected bridge pier and use state representation, in this example, protected bridge pier 1 has three (protected bridge pier 1 can be more than this number also can be less than this number, according to the actual situation of bridge Depending on the situation), a fixed pier 4 is arranged on the bank revetment 8 under the bridge deck 9, the floating flexible anti-collision body 2 is located on the side of the river center of the outermost protected pier 1, and the support structure 3 is connected to the floating Between the floating flexible anti-collision body 2 and the fixed pier 4, when the highest navigable water level, the floating flexible anti-collision body 2 and the support structure 3 of...

Abstract

The invention discloses a vertical rotating floating pier anti-collision device, belonging to the technical field of bridge collision avoidance. The vertical rotating floating pier anti-collision device comprises three parts, namely a fixed pier, a floating flexible anti-collision body and a support structure, wherein the fixed pier arranged on a bank is fixedly connected with slope protection of the bank into a whole; the floating flexible anti-collision body is arranged at the center of a river close to a protected pier; the front end of the support structure is fixedly connected with the floating flexible anti-collision body, and the rear end of the support structure is connected with the fixed pier by virtue of a rotating structure; the floating flexible anti-collision body and the support structure which can float up and down along with the variation of water level are separated from the protected pier, and a gap which can cause the device to move up and down between the highest water level and the lowest water level is kept among the floating flexible anti-collision body, the support structure and the protected pier. The device disclosed by the invention is reasonable in design, has simple structure, can ensure a bridge and a ship not to be damaged by collision, is easy to 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, a small number of bridges have received anti-collision protection, but in these technologies, only simple anti-collision protection is provided for bridge piers i...
