Energy-absorbing road traffic combined anti-collision pier and building method thereof

Abstract

The invention discloses an energy-absorbing road traffic combined anti-collision pier which comprises a pier head and a concrete pier body. The pier head comprises a steel plate and a large prism formed by welding and splicing a plurality of round or regular polygon steel tube prisms. The steel plate is located on the periphery of the large prism, extends in the pier body direction and is connected with the pier body. Energy-absorbing materials are injected in gaps in the steel tube prisms, gaps among the steel tube prisms and gaps between the steel plate and the steel tube prisms. By means of the round or regular polygon prisms, people only need to roll the whole steel plate, and a manufacturing process and technology are mature. The aims of collision prevention, energy absorbing and buffering are achieved through a spliced honeycomb structure and filling of metal lead or rubber or other materials. The anti-collision pier breaks whole collision into parts, is convenient to construct and replace, and plays an important role in guaranteeing life safety of traffic drivers and passengers on roads and reducing vehicle property loss.

Description

technical field [0001] The invention belongs to the technical field of anti-collision pier, and in particular relates to an energy-absorbing road traffic combined anti-collision pier and a construction method thereof. Background technique [0002] Road traffic anti-collision piers are generally placed on the roads of roads and urban roads at turns, entrances and exits, toll gates, and other dangerous areas that need to be isolated or anti-collision, for safety isolation, warning, collision prevention and buffering in the event of collision , while absorbing and reducing the impact of collisions. The anti-collision pier can be divided into combined anti-collision pier and cylindrical anti-collision pier according to the shape. The combined anti-collision pier is composed of a pier head and a square pier body. The number of pier bodies can be arbitrarily configured according to the actual situation. The anti-collision pier can be made of concrete, plastic or rubber. When the...
