Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, and more specifically to a guardrail with an anti-dumping function. Background Art

[0002] During municipal road construction, in order to ensure construction safety and prevent outsiders from entering the construction area, guardrails are often used to enclose the construction site.

[0003] However, most of the current guardrails are placed directly on the ground, or are firmly installed on the ground with latches. When a collision occurs between external pedestrians or vehicles and the guardrail, for the guardrail placed directly on the ground, there is a high probability that the guardrail will shift or fall over when subjected to external impact. For the guardrail directly fixed to the ground, when subjected to an impact, due to the rigid collision between the guardrail and external pedestrians or vehicles, it will cause more serious damage to the pedestrians, vehicles and the guardrail itself. After the guardrail is damaged or falls over, it is difficult for it to continue to play a protective role.

[0004] In view of this, the utility model proposes a guardrail with an anti-dumping function to solve this problem. Utility Model Content
