The highway guardrail is strong and beautiful and easy to install. Today we will introduce a highway guardrail is designed.

With the solar LED indicator, it can provide signal instructions for traffic and pedestrians when the light is not good. It brings great convenience to traffic, energy saving and environmental protection. The color of the indicator is yellow. In the night, the lights on the traffic guardrail will flicker frequently and give the pedestrian a vigilant effect. In addition, on the road corner, the height of the traffic barrier can be increased properly, and the distance between the columns can be reduced, so that the risk of high speed driving can be reduced. At the time of design, some changes are made in the style. Under the premise of not affecting the firmness, the diameter of the column, the distance between the columns and the exposure of the green belt can be reduced, which can effectively alleviate the fatigue of the driver of the long driving vehicle. And making appropriate changes in the color of the paint, thus enhancing the wake-up effect of the traffic barrier and greatly improving the maintenance of traffic safety. Of course, we can customize the appropriate a highway guardrail is designed according to the requirements of users.

a highway guardrail is designed safety guarantee for road safety. Therefore, a road guardrail should be installed under the following circumstances:

highway guardrail construction

1, road slope gradient and embankment height in the area above the dotted line.

2, expressway or automobile is within 1 meters from the edge of the earth's shoulder, with the structure of the door frame, the emergency telephone, the pier or the abutment of the bridge.

3, parallel to railways and highways, vehicles may break into adjacent railway or other highways.

4 and the width of the subgrade.

5, the radius of the curve is less than the minimum radius.

6, service area, parking area or speed change lane section at bus stop, including traffic divided and confluent triangle zone.

7, large, medium and small bridge ends or elevated structures at both ends and roadbed connections.

8, diversion island and separation Island consider the place where barrier is needed.

In the section of a highway guardrail is designed, reinforced concrete combined road guardrails are used on the side of large and middle bridge, and wave plate road guardrails are used on the soil subgrade and small bridges, passages and culverts. The ordinary road side guardrail used the ordinary steel plate road guardrail in the soil subgrade section. The spacing of the column was 4 meters. The reinforced steel plate road guardrail was used in the small bridge, the passage and the retaining wall, and the spacing of the column was 2 meters. The road side guardrail column uses 140x4.5 steel tube, the cross beam is 310x85x3 millimeter variable cross section wave beam road guardrail, the height of the guardrail generally uses 60 centimeters. When the fence column is located on the structure, the column should be connected by the compactor.

a highway guardrail is designed to add luster to our city; let our high grade city build a brighter landscape. As road guardrails are separated by motor vehicles, non motor vehicles and pedestrians, the road is divided longitudinally on the cross section to drive motor vehicles, non motor vehicles and pedestrians. Is installed on the road, in order to quickly install the road guardrail, road fence manufacturers are the fastest and safest way to install. The installation process is as follows:

After placing the base, the base is placed in place by distance, and then the road guardrail is placed in sequence in order to the bottom. After placing it, the base is straightened in turn, and the base is fixed on the ground with a professional fixed tool. Finally, the cap, contour mark, anti glare lamp or reflective device are installed on the column. A very safe, convenient and quick installation.

The installation of a highway guardrail is designed one of the slow blocking measures of the traffic police department, which can restrain the random turn off of the motor vehicle, overtake the vehicle, and do not drive in the guide lane, especially when the motor vehicle is turning in the turn, the isolation facility has played an effective separation and transfer function, reducing the conflict and improving the traffic efficiency. The improvement of traffic order has further promoted urban civilization. The steps in installing a road guardrail are as follows:

1、a highway guardrail is designed has been assembled according to the order requirement before leaving the factory. After the product is shipped to the construction site, only the steel lining parts of each column need to be inserted into the stable base, and the layout is lengthening according to the requirements of the use department.

2 、After completing the basic layout, use the special bolts to connect each section of the road guardrail properly.

3、In order to improve the wind resistance and malicious movement of road guardrail, the stable base should be fixed on the ground with the expansion bolt inside the ground.

4、Users are required to install reflectors fixed on the top of the guardrail.

5、Movable cast iron seat can be symmetrical locked with spike or expansion screw.
