Flexible safety protective guard for highway

Abstract

The invention discloses a flexible safety protective guard for a highway. The protective guard comprises a long-strip-shaped PVC resin plate and is characterized in that the inner layer of the PVC resin plate comprises a reinforcing band woven by epoxy glass fiber in at least two directions, a photoluminescent material layer is clamped in the reinforcing band, and a pure polyester thermalsetting powder coating spraying layer wraps the outer layer of the PVC resin plate. According to the protective guard, due to the fact that the reinforcing band woven by the epoxy glass fiber is selected as the inner layer of the PVC resin plate, the elasticity is better when the original anti-impact effect is guaranteed, the impact force can be buffered in collision, and safety is improved. Due to the fact that the photoluminescent material layer is clamped in the reinforcing band, the light reflecting alarming effect of the protective guard can be better under the condition that light is poor at the misty and rainy night.

Description

technical field [0001] The invention relates to a protective device for expressways, in particular to a safety guardrail for expressways. Background technique [0002] In the prior art, the guardrails set up on both sides of the edge of the expressway are usually composed of upright tubes processed by metal materials and guardrails connected to them. In the environment, it is easy to rust and damage, which seriously affects its service life. Moreover, the guardrail board made of metal material has high strength and high hardness. When the guardrail is hit by a car, it lacks elasticity, so it is difficult to reduce the casualties of the vehicle and personnel, and the sparks generated after the collision of the vehicle are also easy to cause fires. . In addition, the night reflection of common guardrails and the warning effect of rain and fog are not good, which also weakens the anti-collision safety performance of guardrails to a certain extent.

Moreover, the guardrail board made of metal material has high strength and high hardness. When the guardrail is hit by a car, it lacks elasticity, so it is difficult to reduce the casualties of the vehicle and personnel, and the sparks generated after the collision of the vehicle are also easy to cause fires.

In addition, the night reflection of common guardrails and the warning effect of rain and fog are not good, which also weakens the anti-collision safety performance of guardrails to a certain extent.
