Abstract

The invention discloses a guardrail height self-adaption method capable of promoting height in impact, comprising a transversely arranged guard plate and a vertically arranged support device, wherein the upper part of the support device is connected with the guard plate so as to fix the height of the guard plate, relative to the ground; and the lower part of the support device is fixedly connected with the ground, and when the guard plate suffers from impact of a vehicle, the guard plate deconstructs the support device with assistance of external force so as to keep or promote the height of the guard plate, relative to the ground.

Description

technical field [0001] The invention relates to the field of high-speed protection, in particular to a guardrail height self-adaptive method for raising the height during impact. Background technique [0002] With the continuous development of our country's economy, the number of urban car ownership continues to increase, and various car accidents on expressways also emerge in endlessly. The inventor has found through research that the limitation of the existing highway guardrails is that it can only be applied to the collision of small vehicles. Large, with strong inertia, once out of control and hitting the highway guardrail, the huge impact force will cause the column fixed with the wave beam to deform and fall along the impact direction, driving the guard plate at the current position to lower its height so that the surrounding wave beam belt A gap is formed, and the out-of-control large vehicle will rush out of the road along the gap, which is likely to cause a major a...
