Bridge guardrails refer to guardrails installed on bridges. Its purpose is to prevent out-of-control vehicles from crossing the bridge, and has the function of preventing vehicles from breaking through, passing under, and over the bridge and beautifying the bridge architecture.
The selection of bridge guardrail form should first determine the anti-collision level based on the highway grade, comprehensive consideration of its safety, coordination, characteristics of the object to be protected and on-site geometric conditions, etc., and then determine the anti-collision level based on its own structure, economy and Factors such as construction and maintenance are used to select the structural form. There are three methods of embedding: direct column embedding, flange connection, and bridge guardrails and bridge decks cast into one through force-transmitting steel bars. When conditions permit, removable guardrails can be used.
