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.
