Self-reset high-speed anti-collision guardrail

Abstract

The invention relates to the technical field of anti-collision guardrails, in particular to a self-reset high-speed anti-collision guardrail, comprising a vertical column, a buffer device and a waveform guardrail plate, the vertical column is vertically fixed, the waveform guardrail plate is arranged on the front side of the vertical column, and the two are assembled into a unified whole through the buffer device; and the vertical column is a hollow pipe, the top part is provided with a column cap, the front and rear sides are provided with screw holes, the middle and lower part is provided with a fixed plate, a limiting column is arranged between the column cap and the fixed plate, and a limiting hole is arranged in the limiting column. As the ultra-high molecular polyethylene (PE) stickpanel is arranged on the surface of the waveform guardrail plate, the friction coefficient (less than 0.2) between the vehicle and the waveform guardrail plate can be reduced, the shear force generated by the vehicle collision with the waveform guardrail plate is greatly reduced, the service life of the waveform guardrail plate is not only prolonged, but also the occurrence probability of the overturning accident is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of anti-collision barriers, in particular to a self-resetting high-speed anti-collision barrier. Background technique [0002] With the rapid growth of the scale of high-grade highway construction in our country, the safety and security facilities of the highway itself have gradually attracted people's attention, especially in special sections such as cliffs, rapids, and steep slopes, it is particularly important to ensure the safety and practicability of high-speed anti-collision barriers. important. A large amount of research data shows that the high-speed anti-collision barrier should not only have a relatively high mechanical strength to resist the impact force of the vehicle, but also cannot make its rigidity too large, so as to avoid serious injuries to the occupants of the vehicle. Therefore, while the construction network of high-grade highways continues to develop, setting up safe and effective hig...

Problems solved by technology

However, because the collision is a semi-rigid collision, the kinetic energy during the collision cannot be effectively converted into potential energy, and the corrugated guardrail and the front of the car are easily damaged, and the occupants in the car cannot be effectively protected.
