Highway bridge

Abstract

The invention relates to the technical field of highway bridges, and discloses a highway bridge which comprises a bridge pier, the upper surface of the bridge pier is fixedly connected with a bridge floor, the bridge pier comprises a body, a spring groove is formed in the front face of the body, a telescopic groove is formed in one side of the body, and a sliding groove is formed in the inner bottom wall of the telescopic groove. According to the highway bridge, through cooperation of a corrugated plate, a first spring and a rubber rod, impact on the front face of the bridge pier is weakened to the minimum layer by layer, the front face of the bridge pier is protected, and through arc-shaped arrangement of the side face of an anti-collision block, the anti-collision block can slide inwards along a telescopic groove when being impacted; the telescopic plate pushes a sliding block to compress the rectangular spring and slide along the inner wall of an outer cylinder, the rectangular spring generates thrust to the outer cylinder, the outer cylinder pushes the roller, the sliding rod slides along the inner wall of the sliding groove and extrudes the second spring, and therefore the highway bridge solves the problem that vehicles and bridge piers are seriously damaged due to vehicle accidents.

Description

technical field [0001] The invention relates to the technical field of highway bridges, in particular to a highway bridge. Background technique [0002] Highway and bridge engineering includes the main body of the bridge, that is, the bridge superstructure and bridge substructure engineering, and the auxiliary engineering facilities in the overall bridge position. [0003] Some of the bridge piers of highway bridges are set not far from the road. When a vehicle has an accident, it is easy to crash into the bridge piers and cause damage to the bridge piers. However, the existing highway bridges are not equipped with anti-collision structures at the bridge piers, so that vehicles and bridge piers severely damaged; [0004] For this reason, propose a kind of highway bridge. Contents of the invention [0005] Aiming at the deficiencies of the prior art, the present invention provides a highway bridge to solve the problems raised in the background art. [0006] To achieve th...
