Description

Technical Field

[0001] The utility model relates to the technical field of highway reconstruction and expansion isolation guardrails, and more specifically, to a movable steel guardrail for highway anti-collision. Background Technique

[0002] The isolation guardrail for highway reconstruction and expansion is a safety protection barrier that separates the construction area workers from the traffic flow. If a vehicle collides with or crosses the isolation guardrail during a traffic accident, it will directly pose a life threat to the construction area workers. Therefore, when setting up the isolation guardrail, its anti-collision performance should be comprehensively considered. At present, most of the isolation guardrails for construction areas in China use road cones, water horses, cement piers, etc., which are difficult to meet the requirements for protecting the lives and safety of construction workers due to their poor anti-collision performance.
