What kind of highway guardrail

Nowadays, in order to ensure the safety on the roads, more and more traffic safety facilities have been added to the roads. We often see road barriers. There are many types of highway guardrails, which can be divided into flexible guardrails, rigid guardrails, and semi-rigid guardrails according to their different stiffnesses.

1. A semi-rigid guardrail generally refers to a continuous beam-type guardrail structure. The semi-rigid guardrail is a beam-type structure that is fixed by struts and relies on the bending deformation and tension of the guardrail to resist the collision of the vehicle. The beam barriers can be divided into W-shaped beam guardrails, tubular beam guardrails, box girder guardrails, etc. according to different structures. This guardrail has a certain degree of stiffness and toughness. They absorb impact energy through the deformation of the cross beam. It is easier to replace damaged parts, has a certain visual line induction effect, and the appearance is also more beautiful.

2. Flexible guardrail generally refers to a tough guardrail structure with a large buffer capacity. The flexible fence is a structure that is fixed to the pillar by a number of cables that exert the initial tension. It mainly depends on the tension of the cable to resist the collision of the vehicle to absorb energy. This form of guardrail is generally more beautiful, and there is no feeling of oppression when the vehicle is running.

3, rigid guardrail generally refers to a basic non-deformation of the guardrail structure. The rigid guardrail is a cement concrete wall structure with a certain cross-sectional shape. It absorbs collision energy by relying on the car's height, deformation, and friction. Rigid guardrails are generally not deformed during a collision and are not easily damaged. Maintenance costs are generally low.
