Red Road Highway Roller Barriers Safety 50KM
The rotating anti-collision guardrail combines the advantages of traditional guardrails and new impact-resistant energy-absorbing drums, and realizes the protection method of "one column and four columns". The rotating anti-collision guardrail strengthens the performance of the traditional column and guardrail, so that the impact energy perpendicular to the direction of the guardrail is converted into rotational energy parallel to the direction of the anti-collision rotating barrel. The accident vehicle maintains 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 of the driving lane.
Rotating traffic facility crash barrier working principle Production material
The working principle of the anti-collision guardrail for rotating traffic facilities The production material is impact-resistant and energy-absorbing. The rotating anti-collision barrel is made of high-tech polymer composite material---polyurethane. Due to the high elasticity of the material, the barrel itself has the characteristics of high elasticity and anti-collision and wear resistance, which can avoid being broken when impacted, and at the same time effectively protect the guardrail and the passengers.
Features:
The guardrail consists of upright columns, rotating barrels, U-shaped beams and connecting pieces, and all steel components are treated with hot-dip galvanized anti-rust treatment.
The columns are separated by 1 meter or 0.7 meters, and two rotating barrels are installed on each column. The rotating barrel is made of EVA (ethylene-vinyl acetate copolymer) as the main material, and 17 kinds of auxiliary materials such as PE (polyethylene) and related chemical additives are added. It is made under certain temperature and pressure, and has extremely high flexibility. flexibility and resilience, and high temperature resistance,
Continuous operating temperature between -60°C and 70°C. Such guardrails are usually installed on highway ramps, continuous descents and curves.
When the vehicle hits the guardrail, the rotating function of the rotating bucket itself and the good resilience of the bucket body can greatly reduce the degree of injury to the vehicle and the driver and passengers, and play a good protective role.
Reflective strips are attached to the rotating barrel. When driving at night, through the illumination of lights, the outline of the route can be better reflected, which has a better vision-inducing effect on the vehicle and further ensures the safety of driving.
