AI Technical Summary
Existing highway crash barriers have low buffering capacity, resulting in strong impact forces and generally poor safety performance during car collisions.
A highway anti-collision structure was designed, including an outer protective component, an inner protective component, an outer buffer component, and an inner buffer component. It adopts a pointed structure and uses components such as corrugated beam steel guardrails, water storage frames, arc-shaped convex plates, and water storage tanks to form a multi-layer buffer area. These components are fixed to the corrugated beam steel guardrails with bolts to form inner and outer buffer areas.
It effectively cushions the impact of frontal or side collisions, improving crash safety and reducing damage during a collision.

A buffer outer component (3) is provided between two adjacent outer protective components (1) and inner protective components (2). A front protective component (4) is provided at the front end of the two outer protective components (1) and inner protective components (2). A buffer inner component (5) is provided between the two inner protective components (2). The highway anti-collision structure is a pointed structure. The outer protective component (1) includes a corrugated beam steel guardrail (11). The inner side of the corrugated beam steel guardrail (11) is provided with a first mounting frame (12). The top of the first mounting frame (12) is welded with a first mounting seat (13). The first mounting seat (13) is fixedly installed on the inner side of the corrugated beam steel guardrail (11) by bolts. The bottom end of the first mounting frame (12) is fixedly installed with a first fixed base (14). The first fixed base (14) is provided with a first pre-embedded bolt (141).
2. A crash barrier according to claim 1, wherein: The structure of the inner protective component (2) is the same as that of the outer protective component (1).
