[0049] Working principle of the transition section between the corrugated beam guardrail and the metal beam-column guardrail:

[0050] When a vehicle that deviates from the normal trajectory collides, it first contacts the arc guide plate 6, and the elastic telescopic component 5 is compressed. The elastic telescopic component 5 plays a role in buffering and energy storage. Since the arc guide plate 6 is a arc plate, it can guide the direction of the vehicle's impact. The vehicle's impact surface moves relative to the outer side of the arc guide plate 6, and finally collides with the corrugated beam guardrail 2 or the metal beam-column guardrail 3. Due to the guiding effect of the arc guide plate 6, the guardrail connection mechanism 1 is prevented from receiving more impact energy. Compared with the corrugated beam guardrail 2 and the metal beam-column guardrail 3, the guardrail connection mechanism 1 is relatively weak, which guides the corrugated beam guardrail 2 or the metal beam-column guardrail 3 to receive more impact energy, and the protective effect is good.
