The rotating barrel guardrail advantages: 1, the rotating barrel made of composite materials EVA and polyurethane, the high strength EVA and polyurethane material itself and elastic collision resistant, can avoid being smashed the rotating barrel under impact, effectively to the fence and crew protection. 2, in addition to the collision also has good abrasion resistance, chemical resistant, anti UV, anti aging advantages of TCM, not easy to be damaged, beautiful appearance, easy to fade, outdoors under natural conditions, the service life of at least ten years. Once a traffic accident occurs, when the car hit it, through rotation, the conversion of collision energy into rotational energy, keep the car's normal driving direction and speed, reduce the incidence of traffic accidents, protect people's personal safety, provide a new road safety guarantee. 3, there is a strong rotating bucket resilience, even if it is a serious impact, but also can immediately restore the original. 4, the rotating barrel, the appearance of bright colors, yellow, orange, green, light reflecting effect of height, eye capture function, can cause the driver's attention, reduce the accident rate, especially to ensure their safety and driving rain at night.
The utility model has the advantages that: the utility model is suitable for the installation and application of the multi side of the tunnel mouth, the central isolation belt, the rapid turning zone, the complex intersection, etc..
