Briefly describe the anti-collision bridge guardrail
Bridge guardrails refer to guardrails installed on bridges, also known as crash barriers. Its purpose is to prevent out of control vehicles from crossing the bridge, and it has the function of preventing vehicles from breaking through, underpassing, and climbing over the bridge, as well as beautifying the bridge building.
The selection of the form of bridge guardrails should first be based on the level of the highway, taking into account factors such as safety, coordination, characteristics of the objects to be protected, and site geometric conditions to determine the collision prevention level. Then, the selection of the construction form should be based on factors such as its own structure, economy, and construction and maintenance. There are three burial methods for it: direct embedding of columns, flange connection, and pouring of bridge guardrails and bridge decks into one through force transmitting steel bars. When conditions permit, a replaceable guardrail can be used.
