Product Specification

ISO Standard Roadway Traffic Safe Rolling Type Safety EVA Barrier For High Guardrail

Product description

The new road rotating guardrail is also called the "anti-collision bucket guardrail" or " new type highway roller barriers " . It mainly adopts the "one column and four beams " method . By strengthening the performance and installation method of the column and the fence, it effectively prevents the car from crossing the fence and driving out of the driving lane.

The roller anti-collision guardrail is composed of columns, rollers, U-shaped or W-shaped beams and connecting parts. All steel components are treated with hot galvanized anti-rust. The columns shall be spaced 1 m, 0.7 m or 0.5 m apart, and one roller or two rollers shall be installed on each column. The roller with EVA as the main material and related chemical additives and other 17 kinds of auxiliary materials, under a certain temperature and pressure, made of high flexibility and resilience, and high temperature resistance, continuous working temperature between -60°C and 70°C.

Working principle:

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 improves the installation method by strengthening the performance of traditional columns and guardrails. The rotating bucket can rotate freely on the column. When an accident occurs, the free rotation of multiple groups of anti-collision rotating buckets can effectively decompose the impact force of the car, so that the impact energy perpendicular to the direction of the guardrail can be converted into rotational energy parallel to the direction of the anti-collision rotating bucket. , The combination of this rotational energy and the elastic energy of the rotating barrel can pull the accident vehicle to maintain the normal driving direction and speed, while avoiding the "head-to-head" situation of the vehicle and the traditional guardrail in previous traffic accidents, it can prevent the car from passing through the guardrail and driving out. Drive lanes, thereby effectively reducing the serious consequences of traffic accidents, and protecting the personal safety of drivers and passengers to a great extent.

Such guardrails are usually installed on freeway ramps, continuous dips and curves, etc. When the vehicle hits the guardrail, the roller function of the roller barrel itself and the good resilience of the barrel body can greatly reduce the injury degree of the vehicle and the driver and passenger, and play a good protective role.

Production materials

1. Adopt high-quality original material.

Roller EVA material with elastic characteristics is used as raw material, which can slow down the lateral impact process of the out-of-control vehicle. Moreover, the rotating barrel can rotate around the column under a certain impact, driving the out-of-control vehicle to return to the correct driving direction.

2. High quality steel support.

Using Q235 steel, multiple thick steel fixed, durable, strong protection ability.

3. Strong of lower solid frame.

The round post could buried deep, structural strengthening, can effectively block the front or side impact.

The function of each part of the roller anti-collision guardrail

1. Column: It is driven into the roadbed and is the main force-bearing component.

2. Beam: It is used to connect the columns and fix the rotating barrel.

3. Rotary barrel: It is fixed between the upper and lower beams and can be rotated around the column. The main materials are EVA (ethylene-ester acid copolymer) and polyurethane.

4. Sleeve: It is installed on the inner wall of the rotating barrel and is a touch component with rotating function. 5) Gyratory ring: Installed between the rotating barrel and the beam to balance and promote rotation.

6. Connection frame: used for connection between beams.

7. U-shaped frame: connecting the beam and the column to fix the beam.

8. Pad buckle: Lined with the beam and connected to the U-shaped frame.

9. Hoop: connecting beams and columns, used to fix beams, suitable for specific types.

10. Reflective strips.•It is a reflective film, which is pasted on the rotating barrel and plays an inductive role.

Product application

The appearance color of the rotating anti-collision barrel can be customized into various warning colors, such as yellow, orange, orange, red, green, etc. The high brightness reflection effect makes the anti-collision barrel maintain high recognition and warning degree in bad weather conditions such as night and rainy days, catch the driver's eye, attract the driver's attention, and reduce the accident rate. It is especially suitable for installation in accident-prone areas such as tunnel entrances, central isolation belts, rapid turning areas, complex intersections, etc. Because of its good anti-collision performance, it can also be used as various power facilities, parking lot columns, large shelf corners and other objects. defensive equipment.
