[0002] As the number of cars in the world increases, the number of road traffic accidents also rises. In order to reduce casualties and property losses caused by traffic accidents, governments and traffic management departments have begun to pay attention to the construction of road safety facilities, among which lane guardrails are one of the key protective measures.

[0003] Some existing lane guardrails are designed to be height-adjustable. The guardrail height is adjusted according to different traffic flows and vehicle types. Increasing the guardrail height can better control the movement of large vehicles and reduce the impact on small vehicles. During non-peak hours, lowering the guardrail height can improve the road's traffic capacity.

[0004] However, some existing lane guardrails will have their overall height adjusted when in use, and it is impossible to adjust the beams or baffles that provide partial interception separately. The overall elevation including the supporting part is likely to change the center of gravity and stability of the original structure. If handled improperly, it will cause the structure to become unstable or even collapse. At the same time, some of the obstructed space or area will be exposed when it is raised. If the hollow part formed by the exposed space is too large and not filled, the overall structural integrity of the lane guardrail will be weakened, affecting its ability to resist impact.
