The highway guardrail is a continuous structure, which is mainly composed of corrugated steel guardrails. Every two corrugated steel guardrails are fixed on the guardrail columns by splicing to form a whole. When a car is driving on the expressway, you will see guardrails on both sides of the road. The guardrails are as long as the road is, and the guardrails on the expressway are different from the common guardrails on the road. They can absorb the energy of the collision. , so why does it have the above characteristics? The following high-speed guardrail equipment factory will answer for you.
Classification of highway guardrail
Expressway wave guardrails are generally divided into flexible guardrails, semi-rigid guardrails and rigid guardrails. Flexible guardrails generally refer to cable guardrails, rigid guardrails generally refer to cement concrete guardrails, and semi-rigid guardrails generally refer to beam guardrails.
The highway guardrail should not only prevent out-of-control vehicles from rushing out of the road and colliding with obstacles or other facilities outside the road, or rushing through the central divider into the opposite lane to cause greater traffic accidents, but also enable the vehicle to return to normal driving Direction, the damage to the driver and passengers is small, and it must be able to induce the line of sight.
The beam guardrail is a beam structure fixed by pillars, relying on the bending deformation and tension of the guardrail to resist the collision of the vehicle. The beam guardrail has a certain rigidity and toughness, and absorbs the impact energy through the deformation of the beam, and its damaged parts are easy Replacement has a certain sight-inducing effect, can be coordinated with the road alignment, and has a beautiful appearance. Among them, the wave beam guardrail is widely used at home and abroad in the near future.
