Introduction to the knowledge of guardrail
1. The Highway Guardrail is the main form of semi-rigid guardrail. It is a continuous structure with corrugated steel guardrails spliced with each other and supported by post.
2. It uses the deformation of the soil foundation, columns and beams to absorb collision energy, and forces the out-of-control vehicle to change direction and return to the normal driving direction to prevent the vehicle from rushing out of the road to protect the vehicle and passengers and reduce the loss caused by the accident.
3. The expressway wave guardrail has both steel and flexibility, has a strong ability to absorb collision energy, has a good line of sight guidance function, can be coordinated with the road line shape, and has a beautiful appearance. It can be used on small radius bends and damaged places. Easy to replace.
