Vehicle collision prevention device for bridge pier

Abstract

Provided is a vehicle collision prevention device for a bridge pier, which includes a bionic honeycomb column thin-walled structure arranged on the bridge pier and an anti-collision structure arranged on the bionic honeycomb column thin-walled structure. The anti-collision structure includes a panel, a restraint plate arranged in a circumferential direction of the panel and forming a closed loop, shear nails arranged in an interior of the panel and rib plates arranged on inner walls of the restraint plate and extending into the interior of the panel. In the present disclosure, the panel includes the rib plates and the shear nails, so that an interface bonding force between the ultra-high performance concrete panel and the restraint plate is enhanced, which makes them closely bonded together. The ultra-high performance concrete anti-collision structure and the bionic honeycomb column thin-walled structure are combined together to form a combined structure composed by them.

What is claimed is: 
     
         1 . A vehicle collision prevention device for a bridge pier, comprising a bionic honeycomb column thin-walled structure arranged on the bridge pier and an anti-collision structure arranged on the bionic honeycomb column thin-walled structure, wherein the anti-collision structure comprises a panel, a restraint plate arranged in a circumferential direction of the panel and forming a closed loop, shear nails arranged in an interior of the panel and rib plates arranged on inner walls of the restraint plate and extending into the interior of the panel. 
     
     
         2 . The vehicle collision prevention device for a bridge pier according to  claim 1 , wherein the shear nails are perpendicular to a plane where the panel is located, and the rib plates are perpendicular to the restraint plate. 
     
     
         3 . The vehicle collision prevention device for a bridge pier according to  claim 2 , wherein the restraint plate is rectangular. 
     
     
         4 . The vehicle collision prevention device for a bridge pier according to  claim 3 , wherein the rib plates are T-shaped. 
     
     
         5 . The vehicle collision prevention device for a bridge pier according to  claim 4 , wherein at least three rib plates are arranged at equal intervals on each inner wall of vertical plates of the restraint plate. 
     
     
         6 . The vehicle collision prevention device for a bridge pier according to  claim 5 , wherein the shear nails are arranged at intersections of connecting lines of the rib plates located on opposite faces of the restraint plate. 
     
     
         7 . The vehicle collision prevention device for a bridge pier according to  claim 2 , wherein the panel is made of ultra-high performance concrete. 
     
     
         8 . The vehicle collision prevention device for a bridge pier according to  claim 1 , wherein the bionic honeycomb column thin-walled structure comprises a thin wall and bionic honeycomb columns arranged inside a cavity enclosed by the thin wall. 
     
     
         9 . The vehicle collision prevention device for a bridge pier according to  claim 1 , wherein dimensions of the panel are the same as sectional dimensions of a cavity enclosed by a thin wall.
