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...
