Roadside barriers are used to protect vehicles and occupants from collisions with natural or man-made objects located beside the road. It is important to note that a vehicle hitting a traffic barrier can damage both the vehicle/passenger and the barrier itself. Damage from crashing a guardrail is generally not as severe as crashing a component located behind the guardrail, so traffic guardrails represent a compromise between these two considerations. In addition to protecting vehicles, traffic barriers are also used to shield pedestrians, maintenance/construction personnel, or cyclists from erratic traffic. In its most basic form, a traffic barrier is designed to prevent vehicles leaving the roadway from hitting stationary objects. The guardrail first stops an accident vehicle and then causes it to change direction. Because of the variability of vehicle impact and the destructive effect at high speed, a comprehensive full-scale destructive test should be introduced to ensure the safety and reliability of the traffic barriers to be used.
There are many sizes and shapes of guardrails that can be used. The choice of guardrail type depends on a number of factors, including the environment the road is in as well as speed and traffic volume.
The functions of traffic barriers are:
The first is to prevent the vehicle from rushing out of the road and causing a rollover accident, especially the traffic guardrails set at the bends and dangerous roads in the mountainous area. For motor vehicle drivers, they can attract sufficient attention from a distance, so that they can increase their vigilance. When passing, it can also guide the driver's sight to help him operate correctly.
Second, it can prevent the frontal conflict of the opposite car, and at the same time, it can prevent the rubbing and hanging of the same car;
The third is to prevent vehicles from colliding with pedestrians, and to prevent pedestrians from arbitrarily crossing the road.
What is the difference with the railway guardrail
1. Different varieties
The general traffic guardrail refers to the expressway guardrail net. There are three kinds of expressway guardrail nets that are often used: double-sided guardrail nets, structural guardrail nets, and highway anti-glare nets. Viewpoint bending. Railway fences generally use structural fences as safety protection products. Occasionally, triangular bending fences or Dutch nets, wrought iron fences, etc. are also used, but they are rarely used and not widespread, and in most cases there is no top. 30 degree bend.
2. Different quality
The same is the structural fence, but the ones used on highways and railways are different. Generally, the railways are rich and powerful, and the structural fences used are heavier and of better quality. On the other hand, the structural fences used on highways are relatively frivolous in quality and relatively expensive. It is also cheap. It can be seen that it is the same structural fence, but the quality is very different.
3, the column is different
Highway guardrails often use circular steel pipe columns with a diameter of 48mm for device fixation, while railway guardrails generally use cement components as columns. Even if it is also a steel pipe column, the wall thickness of the column selected on the railway should be relatively thicker, generally around 2.0 , on the road, it is mostly about 1.0.
4. Different heights
The height of the two sides and the structural fence in the highway fence is generally 1.8 meters, and the height of the highway anti-glare network is generally not more than 1 meter, and it will not be too much. The height of the railway fence is not very fixed, often Between 1.4-3 meters, it should be used according to the specific situation.
