EVA Highway Rotating Guardrail,
PVC Coated Highway Rotating Guardrail,
Corrosion Resistant Guardrail Barrier
Domestic and foreign traffic accident research data show that, reasonably set to meet the protection requirements of the guardrail, can effectively reduce the vehicle out of the roadside guardrail or through the secondary collision with the chances of collision, so as to avoid unnecessary property damage and casualties. Rolling crash barrier is mainly used in small radius curve section, tunnel entrance transition, interchange exit triangle end and other dangerous sections. The increase of car ownership makes the road bear the pressure of the vehicle running too much, easy to appear sudden traffic accidents. In the highway traffic accidents, a large number of accidents with the road on both sides of the guardrail collision-related. Guardrail design can make the runaway vehicle in collision with the guardrail to return to the normal direction of travel, maximum absorption of impact energy, reduce the injury to the driver and passengers.
with the guardrail return to the normal driving direction, absorb the impact energy to the maximum extent, and reduce the damage to the
Highway rotating guardrail is suitable for dangerous road sections, such as sharp turns, cliff edges, river edges, etc. Can greatly reduce the severity of the accident. If driving at night, the rotating guardrail has a night light mode. It can effectively remind drivers to pay attention to roadside safety.
The rotating collision guardrail is mainly composed of column, rotating barrel, casing, rubber cushion, swivel ring, beam, reflective strip and bolt. The side view of the guardrail is shown in the figure, using a column and four columns of the installation method.
The rolling safety barrier is made of ethylene vinyl acetate copolymer (EVA) and polyurethane composite material, which is elastic, impact-resistant and wear-resistant and can effectively prevent the rotating barrel from being shattered upon impact, and the good recovery force of the rotating barrel also ensures that it can quickly return to its original state after a serious impact.
The rotating barrel can also rotate freely on the column, through the rotation of the rotating barrel will collision force decomposition, drive the runaway vehicle incidence angle decreasing, the correct completion of the vehicle export to reduce the risk of secondary accidents. In addition, the bright color of the rotating barrel can also improve the driver's attention to ensure driving safety. The protection mechanism of the rotating collision barrier is shown in the figure.
When the vehicle collides with the rotating guardrail, the vehicle will drive the rotating barrel to rotate, and part of the lateral impact force will be transformed into rolling resistance, which will reduce the lateral and longitudinal acceleration values, thus reducing the injury to the driver and passengers, and also reducing the deformation and damage of the vehicle. As the vehicle collision process, the longitudinal force is rolling friction, which is much smaller than the traditional guardrail and the sliding friction between the runaway vehicle, so the rotating collision guardrail can make the collision time shorter, so that the vehicle out of the speed increases, so that the collision process resistance becomes smaller, so as to reduce the difficulty of the driver in the collision process, so that the vehicle as soon as possible and the guardrail out of the collision, the correct completion of the guidance and reduce the risk of the second accident.

With the continuous optimization of the guardrail structure and the continuous development of material science, rotating guardrail can impact a higher level of guardrail protection requirements, the application of dangerous sections of the highway can protect the safety of the occupants and vehicles to a greater extent. Rotating type collision guardrail guide and buffer performance compared with the traditional guardrail have a breakthrough improvement. In addition, rotating collision barrier and landscape natural integration, can improve the road environment greening level, long-term use will not only significantly improve the level of road safety, but also can effectively reduce the direct economic loss, has an important social and economic benefits.
