Main protective forms of highway guardrail boards

The highway guardrail board is mainly used for isolation and protection of highway lanes. The utility model relates to a combined type corrugated plate movable steel guardrail used at the opening of the central dividing strip of the highway. The guardrail is composed of two corrugated steel guardrail boards and two columns fixed and clamped between them, and the two columns are fixed and clamped between the two corrugated steel guardrail boards. During normal operation of highways, this guardrail can be easily inserted into the pre set insertion and extraction holes at the opening using insertion and extraction columns, playing a role in isolation and protection. At the same time, it corresponds to the guardrail strip on the outside of the highway, which is neat, uniform, and aesthetically matched.

Highway guardrail is the main form of semi rigid guardrail, which is a continuous structure consisting of corrugated steel guardrail plates that are interconnected and supported by main columns.Highway guardrail utilizes the deformation of soil foundations, columns, and beams to absorb collision energy and force out of control vehicles to change direction, return to normal driving direction, prevent vehicles from rushing out of the road, protect vehicles and passengers, and reduce losses caused by accidents. The corrugated beam guardrail combines steel and flexibility, has strong ability to absorb collision energy, has good line of sight guidance function, can coordinate with the road alignment, has a beautiful appearance, and can be used on small radius curves, and the damaged parts are easy to replace. Composite corrugated beam guardrails can be used on narrow central partitions. For sections where vehicles may cause serious consequences when crossing the road (bridge), it is advisable to strengthen the corrugated beam guardrail.
