The invention relates to an urban flood disaster intercepting guardrail which effectively solves the problem that in an urban flood disaster, people are likely to be washed away by flood flow on a road surface and are in distress. According to the technical scheme, the guardrail comprises a movable section guardrail body, a rotating shaft assembly is arranged at the midpoint position of the movable section guardrail body, vertical fixing rods fixed to the ground are arranged at the two ends of the movable section guardrail body respectively, the two ends of the movable section guardrail body are locked to fixing rods through pin shafts, and the lower ends of the pin shafts are filled with sand grains. When flood flows exist on the road surface, sand grains run away along with water flow; the pin shaft sinks and is pulled out, the two ends of the movable section guardrail are unlocked, a one-way impeller is arranged on the movable section guardrail, a small gear is fixed to the lower end of the one-way impeller, a large gear is fixed to the lower end of the rotating shaft assembly, and the one-way impeller drives the small gear to revolve around the large gear, so that the movable section guardrail is driven to rotate to a transverse guardrail state; according to the invention, people falling into flood flow can be intercepted and prevented from being washed away, so that casualties in flood disasters are reduced.
本发明涉及一种城市洪涝灾害拦截护栏，有效的解决了城市洪涝灾害中人员易被路面洪流冲走遇难的问题；解决的技术方案包括活动段护栏，活动段护栏的中点位置设有一个转动轴组件，活动段护栏的两端各设有固定在地面上的竖向的固定杆，活动段护栏两端经销轴锁定在固定杆上，销轴下端填充有沙粒，当路面有洪流时，沙粒随水流流失，销轴下沉拔出，活动段护栏两端解锁，活动段护栏上的单向叶轮，单向叶轮下端固定有小齿轮，转动轴组件的下端固定有大齿轮，单向叶轮驱动小齿轮绕大齿轮公转，从而驱动活动段护栏转动至横栏状态；本发明能将跌落在洪流中的人员拦截下来，避免其被冲走，从而减少洪涝灾害中的人员伤亡。
