Debris flow area bridge pier with floating anti-collision device

Abstract

The invention discloses a debris flow area bridge pier with a floating anti-collision device. The debris flow area bridge pier is composed of a pier body, a buffer sleeve, a buoyancy box ring, a connecting frame and a plurality of anti-collision barrels. The debris flow area bridge pier with the floating anti-collision device has the beneficial technical effects that according to the scheme, the impact effect of debris flow on a bridge can be effectively reduced, and the anti-collision performance of the debris flow area bridge is improved.

Description

technical field [0001] The invention relates to a bridge pier protection technology, in particular to a bridge pier in a debris flow area with a floating anti-collision device. Background technique [0002] my country is a country with frequent occurrence of debris flow disasters, and bridges located in debris flow areas are often threatened by debris flow disasters; in order to protect bridges in debris flow areas, the most common means is to set up anti-collision devices such as protective sleeves on bridge piers, and use anti-collision devices to buffer the impact of debris flow Function; the existing problem is: most of the existing anti-collision devices adopt fixed installation methods, and the protection height of the anti-collision devices is limited. In addition, the existing anti-collision devices have poor energy absorption effect and the protection effect is not ideal; in addition, the existing anti-collision devices are generally close to the pier, and the surface...

[0002] my country is a country with frequent occurrence of debris flow disasters, and bridges located in debris flow areas are often threatened by debris flow disasters; in order to protect bridges in debris flow areas, the most common means is to set up anti-collision devices such as protective sleeves on bridge piers, and use anti-collision devices to buffer the impact of debris flow Function; the existing problem is: most of the existing anti-collision devices adopt fixed installation methods, and the protection height of the anti-collision devices is limited. In addition, the existing anti-collision devices have poor energy absorption effect and the protection effect is not ideal; in addition, the existing anti-collision devices are generally close to the pier, and the surface of the pier cannot be observed from the outside. After the debris flow disaster is over, only The pier damage can only be assessed by removing the anti-collision devices
