The invention relates to the technical field of guardrails, and discloses a movable guardrail which comprises stand columns, handrails and ground beams; the handrails and the ground beams are arrangedon the cross section of the guardrail in a mode that the widths are gradually increased; the inclined position of the side surface of a vehicle body can be perfectly matched during lateral impact ofthe vehicle; contact stress, friction and deformation energy consumption with a vehicle body are facilitated; in the collision process, the guardrail directly contacted with the vehicle body adopts anopen thin-wall component; the lateral deformation energy dissipation capability is high; in the collision process, the ground beams which are in direct contact with the vehicle body for a short timeadopts a closed thin-wall component; the lateral torsional rigidity is high; handrail and ground beam materials are combined; meanwhile, the requirements of the movable guardrail for impact energy consumption and rollover blocking performance are met, material selection is proper, materials are fully used, materials are saved, weight is reduced, the handrails are made of national standard open thin-wall profiles, the stand columns and the ground beams are made of closed thin-wall profiles, other components are made of plates, the material standardization degree and the marketization degree arehigh, purchasing is convenient, and the machining and manufacturing process is simplified.
本发明涉及护栏技术领域，且公开了一种移动护栏，包括立柱、栏杆和地梁，栏杆和地梁在护栏横断面上的布置采用宽度逐级扩大的形式，在与车辆侧向冲击时能够完美吻合车身侧面倾斜位，有利于与车身的接触受力和摩擦、变形耗能，在发生碰撞的过程中与车身直接接触的栏杆采用开口薄壁构件，侧向变形耗能能力强，在发生碰撞的过程中与车身直接接触时间少的地梁采用闭口薄壁构件，侧向抗扭刚度大，栏杆和地梁选材的组合，同时满足移动护栏对冲击耗能和阻挡侧翻性能的需要，选材得当，用材充分，省材减重，栏杆采用国标开口薄壁型材、立柱和地梁采用闭口薄壁型材，其余构件采用板材，材料标准化程度和市场化程度高，方便采购，简化加工制作流程。
