Ultra-high strength concrete (UHPC) anti-collision wall

Abstract

The invention discloses an ultra-high strength concrete (UHPC) anti-collision wall which comprises a composite wall body; a supporting seat is fixedly connected to the lower side of the composite wall body; the composite wall body comprises two UHPC plates arranged in parallel and a rubber plate, and the rubber plate is fixedly connected between the two UHPC plates. The UHPC anti-collision wall has the advantages that in the working process of the UHPC anti-collision wall, buffer devices arranged in through holes can effectively buffer the borne impact force, so that the anti-collision wall is not prone to being broken after being collided by a vehicle; meanwhile, a flow guide device arranged on one side of the supporting seat has the air purification performance, and the anti-collision wall is provided with a drainage structure, so that on one hand, the anti-collision wall absorbs harmful gas generated by an automobile and prevents tail gas discharged by the automobile from polluting the road environment, and on the other hand, the anti-collision wall can drain rainwater accumulated nearby the anti-collision wall and prevents the situation that serious water accumulation on the road is not beneficial to running of the automobile.

Description

technical field [0001] The invention relates to the technical field of anti-collision walls, in particular to an ultra-high-strength concrete UHPC anti-collision wall. Background technique [0002] In the separation zone on both sides of the road, anti-collision walls are generally set up to separate them. The existing anti-collision walls are designed more traditionally, just in the shape of low walls poured with cement. It is easy to break after a vehicle collides. At the same time, the anti-collision wall cannot realize the function of purifying the air, and does not have a drainage structure. It cannot absorb harmful gases generated by the car, and cannot discharge the rainwater accumulated near the wall. On the one hand, it leads to vehicle emissions. The exhaust gas pollutes the road environment. On the other hand, the rainwater will rise higher and higher due to the resistance of the wall, resulting in serious water accumulation on the road, which is not conducive to ...

[0002] In the separation zone on both sides of the road, anti-collision walls are generally set up to separate them. The existing anti-collision walls are designed more traditionally, just in the shape of low walls poured with cement. It is easy to break after a vehicle collides. At the same time, the anti-collision wall cannot realize the function of purifying the air, and does not have a drainage structure. It cannot absorb harmful gases generated by the car, and cannot discharge the rainwater accumulated near the wall. On the one hand, it leads to vehicle emissions. The exhaust gas pollutes the road environment. On the other hand, the rainwater will rise higher and higher due to the resistance of the wall, resulting in serious water accumulation on the road, which is not conducive to the walking of vehicles.
