Fabricated foam concrete filled dumbbell-shaped thin-walled pipe bridge pier anti-collision device

Abstract

The invention discloses a fabricated foam concrete filled thin pipe self-buckling system bridge pier anti-collision device; when the device is collided, firstly, a corrugated plate disperses stress, the corrugated plate and regenerated rubber deform to dissipate energy, then a dumbbell-shaped self-buckling system can effectively dissipate energy through mutual friction and plastic deformation, and the impact effect of axle impact on a bridge pier and a vehicle is relieved. After foam concrete is injected into an aluminum pipe, deformation of the aluminum pipe can be restrained, and the impact resistance of a protection device is effectively improved. The dumbbell-shaped aluminum pipe self-buckling system and foam concrete cooperate for protection, rigidity and softness are combined, the bridge pier is protected against damage after being impacted, and the safety of the vehicle and personnel on the vehicle is protected. The device has the advantages of being low in strength, high in energy consumption, convenient to maintain and replace, small in occupied area, environmentally friendly and the like, and the anti-collision requirement of the pier can be met.

Description

technical field [0001] The invention relates to an assembled bridge pier buffer and anti-collision device, which belongs to the technical field of structure protection and bridge pier anti-collision equipment. Background technique [0002] Bridges are one of the important civil engineering infrastructures in our country. With the increase of the number of bridges, the protection problems of bridges are becoming more and more serious. [0003] become an important issue. As the key part of the bridge, the pier is a key part of the bridge. When the vehicle hits the pier, the pier may be damaged and damaged, causing the overall collapse of the bridge, causing serious damage to the safety of life and property, and there is a high repair cost after the pier hits. Therefore, it is particularly important to take effective measures to avoid major damage when vehicles hit bridge piers. [0004] The existing protection measures are mainly divided into two types. One is the traditiona...
