A buffer anti-collision pier

Abstract

The invention belongs to the technical field of bridge protection devices, and in particular relates to a buffer anti-collision pier, which includes a bridge pier and an anti-collision body arranged around the bridge pier. The outer cylinder and the inner cylinder arranged in sequence; the second-level protective cylinder, and its outer wall is in contact with the inner wall of the inner cylinder of the first-level protective cylinder. A buffer mechanism is arranged in the second-level protective cylinder. The mechanism buffers the outer wall of the secondary protective cylinder. After the vehicle hits the anti-collision pier, the first-level protective tube first absorbs a small part of the energy, and then the remaining energy is fully absorbed by the buffer mechanism on the second-level protective tube, which can not only effectively protect the pier from damage, but also reduce the impact of the vehicle. damage.

Description

technical field

[0001] The invention belongs to the technical field of bridge protection devices, in particular to a buffer and anti-collision pier. Background technique

[0002] At present, the current situation of road traffic safety in our country is worrisome. Due to the increase in traffic volume, the contradiction between cars and bridges (especially overpass bridges) has become more and more prominent. Accidents of cars hitting bridge piers often occur, and in severe cases, bridge piers will collapse. The car crash caused irreparable loss of life and property. The reason is that the direct impact of the car on the bridge pier is a rigid impact, and this process lacks energy dissipation, so the damage is extremely great.

[0003] The anti-collision pier is a device used to protect the bridge pier, and the purpose of impact buffering is achieved through the protective pier. The Chinese invention patent with the publication number CN108474186B discloses a plastic guard...
