[0002] Bridge guardrails refer to guardrails installed on bridges to prevent out-of-control vehicles from running over the bridge. They have the function of preventing vehicles from breaking through, passing under, or climbing over the bridge, as well as beautifying the bridge structure. Reasonable setting of bridge guardrails can not only prevent vehicles from rushing over the guardrails, avoid or reduce secondary accidents caused by vehicles rushing over the bridge, but also have great significance for the safe passage of bridges. It is an important protective facility to ensure the safe passage of vehicles and the safety of surrounding people and property.
