An expressway anti-collision guardrail comprises a base, a fire box is fixed to the upper end face of the base, and three buffer assemblies used for reducing automobile impact force are arranged on the left side of the fire box; the buffering cylinder arranged on the periphery of the center shaft rolls when being impacted, so that a vehicle moves forwards or backwards along the guardrail after impacting the guardrail, part of kinetic energy generated by vehicle impacting is counteracted, and meanwhile, when the vehicle impacts the guardrail, the center shaft can be driven by the buffering cylinder to move forwards or backwards under the action of impact force. The center shaft rotates rightwards with the hinge point of the upper hinge seat and the hinge rod as the center, the lower end of the center shaft inclines rightwards, then the center shaft and the buffer cylinders on the upper side and the lower side integrally move rightwards, part of kinetic energy generated by vehicle collision is absorbed through the buffer springs, and the rightwards-inclined center shaft can reduce the possibility that a vehicle rolls after colliding with the guardrail. And in addition, after the buffer rod moves rightwards, fire extinguishing agent foam in the fire fighting cavity can be sprayed to the automobile through the nozzle, and spontaneous combustion after the automobile is impacted is avoided.
一种高速公路防撞护栏，包括底座，底座上端面固定有消防箱，消防箱左侧设置有三组用于降低汽车冲击力的缓冲组件；本发明通过设置在中心轴外周上的缓冲筒在受撞击时滚动，使得车辆在撞击护栏后沿护栏向前或向后运动，以实现抵消部分车辆撞击的动能，同时在车辆撞击护栏时，中心轴在冲击力的作用下，其以上铰接座和铰接杆的铰接点为中心向右转动，使得中心轴下端向右倾斜，而后中心轴连同上下两侧的缓冲筒整体向右运动，通过缓冲弹簧吸收车辆撞击的部分动能，向右倾斜的中心轴能够减小车辆撞击护栏后翻滚的可能性，避免二次事故的发生，而且在缓冲杆向右运动后，消防腔内的灭火剂泡沫能够通过喷嘴向汽车喷射，避免车辆撞击后发生自燃。
