Abstract
Description

[0002] With the continuous development of economic construction, transportation is becoming increasingly busy. Traffic accidents are currently most frequent on highways or highway bridges. In order to reduce the occurrence of traffic accidents, anti-collision guardrails are installed on both sides of the highway.
[0003] Most of the existing anti-collision guardrails are made of iron structures and are mechanically fixed on both sides of the highway. Although this rigid anti-collision guardrail has strong protective capabilities, when a car collides with the guardrail, under the action of the instantaneous impact load, the anti-collision guardrail basically does not move or deform. As a result, the kinetic energy generated by the collision between the guardrail and the vehicle acts completely on the vehicle and the guardrail, and the kinetic energy generated by the collision cannot be effectively absorbed. The buffering effect is relatively poor, causing greater damage to the vehicle. Utility Model Content
