Traffic fencing function

The traffic barrier acts as a positive effect on traffic safety on the road, but at the same time, the guardrail itself is also an obstacle. Its setting is also conditional, usually after comparing the relative dangers of setting the guardrail and not setting the guardrail. To make a judgment, only the correct plan can realize the function and policy of the guardrail.

The setting guidelines for road side guardrails are mainly divided into embankment guardrails and obstacle guardrails. The minimum length of roadside guardrails is 70 meters. When the distance between two guardrails is less than 100 meters, it is better to be in the two sections. Set continuously. In the roadside guardrail planning, it is necessary to set up a guardrail if one of the following conditions is met:

 

1. The expressway or automobile-dedicated first-class highway has waters such as rivers, rivers, lakes, seas, and swamps within a distance of 1.0 meters from the foot of the roadbed. Vehicles that fall into the city will have extremely dangerous sections.

 

2. The section between the slope of the roadside slope and the height of the embankment.

 

3, the highway interchanges the three-dimensional cross-in and out of the triangle of the ramp and the outside of the small radius of the ramp.

 

4. Intersection with railways and highways, vehicles may fall to the intersection of railways or other roads.

 

Only on the premise of maintaining safe roads and not affecting long roads, the road guardrails set up are beneficial to the people.
