Anti-collision structure of highway vehicles

Abstract

The invention discloses an anti-collision structure for highway vehicles. The lower parts of all foundation piles are connected by a lower horizontal guardrail belt. The lower horizontal guardrail belt is formed by sequentially connecting several sections of lower horizontal guardrails. The joints are fastened by bolts; the upper horizontal guardrail is equidistant along the length direction with upper wire rope holes, the middle horizontal guardrail is equidistant along the length direction with middle wire rope holes, and the lower horizontal guardrail is equidistant along the length direction. The lower steel wire rope holes are equidistant; the upper, middle and lower horizontal guardrails are connected by a steel wire rope, and the steel wire ropes pass through the corresponding steel wire rope holes on the upper, middle and lower horizontal guardrail belts in turn, so that the steel wire ropes form a serpentine structure . In this case, the middle and lower horizontal guardrails are added on the basis of the upper horizontal guardrails. These three horizontal guardrails are connected by steel wire ropes, similar to tying multiple chopsticks together with ropes, organically connecting them into an inseparable whole.

Description

technical field [0001] The invention belongs to the field of expressways, in particular to an anti-collision structure for expressway vehicles. Background technique [0002] With the development of society and technology, expressways are becoming more and more popular. The speed of vehicles on the highway is relatively fast. Once an accident occurs, it is likely to rush out of the road and cause serious traffic accidents. In order to avoid the above situation, highway anti-collision barriers are generally installed on both sides of the expressway at present. The pile foundations of this anti-collision barrier are fixed on the ground, and the pile foundations on each side are arranged equidistantly along the extending direction of the highway. The upper part is connected by a horizontal guardrail belt, which is formed by successively connecting several sections of horizontal guardrails, and the joints are connected by bolts. However, due to the fast speed of vehicles on the...

Problems solved by technology

However, due to the fast speed of vehicles on the expressway, the kinetic energy of crashing into the guardrail after a traffic accident is very large. A high-speed vehicle can easily crash into a certain section of the horizontal guardrail and rush out of the road, causing serious safety accidents. Urgent need to solve the above technical problems
