Anti-collision facility for bridge pier

Abstract

The invention discloses an anti-collision facility for a bridge pier. The anti-collision facility for the bridge pier is characterized in that a plurality of anti-collision columns are distributed on the upper surface of a bearing platform by surrounding a pier stud, to serve as the main body structure for dissipating energy, and the adjacent anti-collision columns are connected by anti-collision systems. According to the invention, the work quantity of civil engineering is smaller, the implementation is not influenced by the geological conditions and the depth of river beds, and the to-be-protected bridge pier stud is not subjected to the impact force. In addition, ships can be protected, and the damage degree of the ships is lowered.

Description

technical field [0001] The invention relates to bridge civil engineering design, in particular to a bridge pier anti-collision facility. Background technique [0002] With the development of transportation, there are more and more large bridges spanning navigable rivers, port areas, and straits. At the same time, the number, tonnage, and speed of ships are also increasing. Major marine accidents caused by ships colliding with bridges and causing bridge collapses are increasing. Serious and increasing trend. [0003] Currently commonly used anti-collision facilities can be divided into two categories: [0004] One is the indirect type, which is characterized by: setting up anti-collision facilities outside the pier, such as pile groups, gravity pendulums, cofferdams, artificial islands, anchored floating bodies, etc. Although this indirect anti-collision facility can prevent the pier from being directly subjected to the impact force, it is difficult to implement such a faci...

AI Technical Summary

Problems solved by technology

Although this kind of direct anti-collision facility can be used in places where the waterway is narrow and the water is deep, and the construction cost is relatively low, and the amount of civil engineering is not large, the impact force still directly acts on the pier after being buffered, causing future troubles.
