Technical Field

[0001] The present application relates to the field of road safety protection, and particularly to a reinforced transformation structure for a corrugated beam guardrail. Background Art

[0002] The corrugated beam guardrail is an important traffic safety facility, which is widely used in road projects such as highways, expressways, bridges, and tunnels. The corrugated beam guardrail is a traffic safety facility composed of corrugated beams, columns, and anti-collision blocks, etc. It uses the corrugated beam as the main load-bearing member and is fixed to both sides of the road or the central isolation belt through columns to form a continuous protection barrier.

[0003] With the increase in traffic flow and the improvement of vehicle performance, especially the popularization of large vehicles (such as heavy trucks, buses, etc.), the collision energy that may be generated by vehicles during driving has increased significantly. The traditional corrugated beam guardrail may not fully consider this increase in energy during design and manufacturing, so its protection ability may be insufficient. Summary of the Utility Model
