[0002] Guardrail is a safety facility, mainly used to prevent people or objects from crossing, and plays the role of separation, guidance and protection. Guardrail can be made of different materials, such as iron, wood or metal, and different structures and styles can be designed according to different environments and needs.

[0003] A road and bridge guardrail refers to a guardrail installed on a road and bridge. Its purpose is to prevent out-of-control vehicles from going over the bridge. It has the function of preventing vehicles from breaking through, passing under, or climbing over the road and bridge, as well as beautifying the road and bridge construction. In the prior art, most road and bridge guardrails are usually fixed and connected by welding. When a traffic accident occurs, the car is likely to rush out of the guardrail and affect the traffic on other roads, or even fall into the water or fall into a valley, causing greater losses and insufficient safety. Therefore, it is necessary to redesign a multifunctional road and bridge guardrail to address the above problems. Utility Model Content
