Abstract

The invention discloses an anti-collision device of a bridge pier, and the anti-collision device comprises a plurality of corrugated steel plate shock-absorption layers (2 to 4), wherein the corrugated steel plate shock-absorption layer (2) on the innermost layer is fixedly connected with the bridge pier (1), two adjacent corrugated steel plate shock-absorption layers are fixedly connected with each other, corrugation lines of the two adjacent corrugated steel plate shock-absorption layers are vertical to each other, the corrugated steel plate shock-absorption layer (4) on the outermost layer surrounds the bridge pier (1) to form a tubular protection layer, and the corrugation direction is in the tangential line direction of one peak on the cross section of a corrugated steel plate. The anti-collision device of the bridge pier has the advantages of convenience in construction and repairing, material conservation and capability of greatly reducing the damage of the bridge pier.

Description

technical field [0001] The invention relates to the field of bridges and roads, in particular to an anti-collision device for bridge piers. Background technique [0002] The pier anti-collision device is an energy-absorbing structure. Through the deformation of the device to absorb the collision energy, and to change the direction of the accident vehicle to protect the pier, while protecting the pier, it is necessary to minimize the damage to passengers. Traditional bridge pier protection devices include rigid crash barriers and flexible crash barriers. The rigid anti-collision fence is a non-deformable guardrail device installed on the anti-collision surface of the bridge pier. The main form is a concrete guardrail. The rigid guardrail plays a role in protecting the bridge pier to a certain extent. It does not have an effective protective effect, and causes great damage to accident vehicles or ships; flexible anti-collision facilities have greater cushioning and energy-a...
