Description

Technical Field

[0001] The utility model relates to the technical field of highway guardrails, in particular to a wing wall transition section guardrail. Background Art

[0002] In the existing technology, concrete wing walls are mostly used to transition between the bridge section guardrail and the roadbed section guardrail, wherein one end of the concrete wing wall is connected to the bridge section guardrail, and the other end is connected to the roadbed section guardrail. However, the on-site construction of the concrete wing wall is difficult. The concrete wing wall made on site requires time to solidify, and the construction period is long, which is easy to affect the road section open to traffic.

[0003] However, existing wing wall structures are rigid overall, making it easy for a driver's head to strike the guardrail directly in the event of a collision, resulting in injury. Furthermore, the lack of a warning structure reduces vision when a driver is fatigued, making accidents more likely to occur. Therefore, those skilled in the art have provided a wing wall transition guardrail to address the issues raised in the background art. Utility Model Content
