[0002] A concrete prefabricated guardrail is a kind of concrete guardrail component that is pre-produced in a factory and then transported to a construction site for installation. It is usually made of reinforced concrete and has high strength and durability. Due to its strong durability, the maintenance cost is relatively low, and only regular inspection and cleaning are required. Concrete prefabricated guardrails are widely used in traffic engineering such as highways, bridges, urban roads, etc., to separate lanes and protect pedestrians.
