Impact-Resistant Energy-Absorbing Drum for Road Protection
working principle
The rotating anti-collision guardrail combines the advantages of the traditional guardrail and the new impact-resistant energy-absorbing drum, and realizes the protection method of "one column and four columns". The rotating anti-collision guardrail improves the installation method by strengthening the performance of traditional columns and guardrails. The rotating barrel can rotate freely on the column.
When an accident occurs, the free rotation of multiple groups of anti-collision rotating barrels can effectively decompose the impact force of the car, so that the impact energy perpendicular to the direction of the guardrail can be converted into rotational energy parallel to the direction of the anti-collision rotating barrel , the combination of the rotation energy and the elastic energy of the rotating barrel can pull the accident vehicle to maintain the normal driving direction and speed, while avoiding the "head-to-head" situation between the vehicle and the traditional guardrail in previous traffic accidents, it can prevent the car from passing through the guardrail and driving out driving lanes, thereby effectively reducing the serious consequences of traffic accidents and greatly protecting the personal safety of drivers and passengers.
production material
The anti-shock and energy-absorbing rotary anti-collision bucket is made of high-tech polymer composite material---polyurethane, which is made and molded as a whole at one time. The polyurethane material has the high strength of the polyethylene material and the high elasticity of the rubber material, so the barrel itself has the characteristics of high elasticity and anti-collision and wear resistance, which can avoid being smashed when being impacted, and at the same time effectively protect the guardrail and passengers. for protection.
In addition, the rotating anti-collision bucket also has a strong recovery ability, and can quickly restore its original shape and performance in the event of a severe impact, which can save road maintenance costs. In addition to good anti-collision and wear resistance, the rotating anti-collision barrel also has corrosion resistance, anti-aging, weather resistance, not easy to break, beautiful appearance, not easy to fade, and many other advantages. Under natural outdoor conditions, the service life can reach ten years. more than a year.
