Separate-type bridge pier anti-collision system

Abstract

The invention discloses a separate-type bridge pier anti-collision system which comprises an anti-collision body. The anti-collision body is arranged on the periphery of a bridge pier and fixed to a steel plate embedded in a bearing platform through a welding process; the anti-collision body is characterized by comprising an air isolation layer, an inner protective cylinder, a buffer layer and an anti-collision layer, wherein the air isolation layer wraps a bridge pier column, the inner protective cylinder wraps the air isolation layer, and the buffer layer is arranged on the periphery of the inner protective cylinder, and the periphery of the buffer layer is wrapped by the anti-collision layer; the bottom of the anti-collision body is fixedly connected with the steel plate embedded on the bearing platform through welding. The separate-type bridge pier anti-collision system has the advantages of achieving a very good energy absorption effect, being replaceable, low in maintenance cost and environmentally friendly and the like.

Description

technical field [0001] The invention belongs to the technical field of bridge pier anti-collision, in particular to a separate type bridge pier anti-collision system. Background technique [0002] With the continuous improvement of my country's infrastructure construction, the scale of long-span bridges and large-span building structures continues to expand, and it is particularly important to ensure structural safety. Accidents of vehicles (ships) colliding with bridges have been happening all over the world, causing unbearable losses of life and property. Therefore, it is particularly important to take anti-collision measures for bridges. Generally, the impact resistance of bridges can only be provided by the anti-collision protection system to buffer the impact force of vehicles (ships) and minimize the loss of bridge piers and vehicles (ships). Through the setting of the anti-collision system around the bridge pier, the collision time of the vehicle (ship) is prolonged ...
