Traffic Plastic Pliable Barrierspiral Staircase Guardrail

The "one column and four columns" method is adopted, and the performance and installation method of the column and the guardrail are strengthened to effectively prevent the car from passing through the guardrail and driving out of the driving lane. And a rotating structure is adopted to support the elastic and anti-collision and wear-resistant rotating barrel on the column, so that the rotating barrel can rotate freely on the column. The impact force of the direction is decomposed into the direction parallel to the guardrail, which is effectively absorbed and reduced by the rotating barrel, thereby effectively reducing the consequences of traffic accidents.

Working principle:

The highway rotating barrel guardrail innovatively adopts a rotating structure, which supports the elastic and anti-collision and wear-resistant rotating barrel on the column, so that the rotating barrel can rotate freely on the column. Rotation decomposes the impact force of the car, so that the impact force perpendicular to the direction of the guardrail is decomposed to the direction parallel to the guardrail, which is effectively absorbed and reduced by the rotating barrel, thereby effectively reducing the consequences of traffic accidents.

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.
