What is the principle of wavy crash barrier?

Corrugated beam guardrail consists of two corrugated beam steel guardrail plates and two guardrail posts fixedly clamped between the two corrugated beam steel guardrail plates, and the two guardrail posts are fixedly clamped between the two corrugated steel guardrail plates. During the normal operation of the expressway, the guardrail can be easily inserted into the preset plugging hole at the opening by using the plugging steel column, which plays the role of isolation and protection, and echoes with the guardrail belt outside the expressway, which is unified and beautiful. When a vehicle collides with it, the corrugated steel guardrail plate is not easy to be damaged because of its good crashworthiness and energy absorption, and it can also protect the vehicle and the driver. When road maintenance or other reasons require parallel traffic, each group of guardrail posts at the opening can be conveniently pulled out and removed, thus opening a passage for vehicles to pass.

Principle:

1. Corrugated beam guardrail is the main form of semi-rigid guardrail, which is a continuous structure formed by splicing corrugated steel guardrail plates and supported by columns.

2. It uses the deformation of soil foundation, columns and beams to absorb collision energy, forcing out-of-control vehicles to change direction and return to normal driving direction to prevent vehicles from rushing off the road, thus protecting vehicles and passengers and reducing losses caused by accidents.

3. The corrugated beam guardrail has both flexibility and rigidity, strong ability to absorb collision energy, good line-of-sight sensing function, beautiful appearance, can be used in small radius bends, and the damaged parts are easy to replace.
