Steel Highway Guardrail Rotating Wave Guardrail
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
It has reached the four-level (SB level, protection energy ≥ 280KJ) protection level specified in the "Highway Guardrail Safety Performance Evaluation Standard" (JTG B05-01-2013);
Suitable for diversion ramps, bends, tunnel entrances, both ends of bridges and accident-prone sections;
Through the rotating bucket, the sliding friction when the vehicle collides with the guardrail is converted into rolling friction, which has good guiding and buffering properties, and can quickly restore the running state of the vehicle and reduce the damage to the guardrail and the vehicle;
With a variety of transition section designs, it can be smoothly connected with various types of concrete guardrails and corrugated beam guardrails.
