Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge guardrails, in particular to a road and bridge guardrail. Background Art

[0002] Road and bridge guardrails refer to guardrails installed on road and bridge guardrails. They use the deformation of the soil foundation, columns, and beams to absorb collision energy, and force out-of-control vehicles to change direction and return to the normal driving direction to prevent vehicles from running off the road. They have a strong ability to absorb collision energy, thereby protecting passengers and vehicles, reducing losses caused by accidents, and reducing economic losses.

[0003] The prior art discloses a road bridge guardrail (announcement number: CN220953128U). Although it is easy to repair and replace and can be adjusted in height as needed, the road bridge guardrail does not protect pedestrians and may cause accidents due to pedestrians accidentally climbing over it. In addition, when a vehicle slightly collides with the guardrail, the steel barrier is relatively hard and the replacement cost is high.

[0004] Therefore, those skilled in the art provide a road bridge guardrail to solve the problems raised in the above background technology. Utility Model Content

[0015] The utility model provides a road bridge guardrail, which has the following beneficial effects:

[0016] (1) By setting a handrail component on one side of the column, pedestrians can pass through the bridge by holding the cylindrical steel pipe. By setting an anti-climbing component above the barrier, pedestrians can avoid accidents caused by accidental climbing over and ensure the safety of pedestrians. By setting a protective component, when a vehicle slightly rubs against the guardrail, the second main frame and the baffle are made of plastic, resulting in less injury and loss, and simple replacement.
