Anti-collision guardrail for highway bridge
The invention relates to an anti-collision guardrail for a highway bridge, and belongs to the field of guardrails. The anti-collision guardrail comprises a lower bent rail, an upper bent rail arranged above the lower bent rail and a plurality of buffer columns which are parallel to one another and arranged between the upper bent rail and the lower bent rail, wherein the buffer columns are fixedly connected with the lower bent rail and the upper bent rail respectively, the lower bent rail is fixedly arranged on a base plane, a lifting resisting device is arranged between every two adjacent buffer columns, each lifting resisting device comprises a fixed column and a lifting column, the fixed columns are buried in the foundation, the lifting columns are arranged in the fixed columns in the length direction of the fixed columns in a sliding mode, and the lifting columns can extend to the positions above the upper bent rail; the lifting resisting devices further comprise a control mechanism used for controlling the lifting columns to slide. When a vehicle collides with the buffer columns, the lifting columns move upwards to the positions above the buffer columns, and then the protection height of the anti-collision guardrail is increased, so that the vehicle is not prone to rollover under the action of the lifting columns, and the vehicle and a driver are protected.
本申请涉及一种公路桥梁用防撞护栏，属于防护栏的领域，包括下弯轨、设置在下弯轨上方的上弯轨以及多根相互平行并设置在上弯轨和下弯轨之间的缓冲柱，所述缓冲柱分别与下弯轨和上弯轨固定连接，所述下弯轨固定设置在基面处，所述相邻的两根缓冲柱之间设置有升降抵挡装置，所述升降抵挡装置包括固定柱和升降柱，所述固定柱埋设于地基内，所述升降柱沿固定柱长度方向滑动设置在固定柱内，且升降柱可延伸至上弯轨的上方位置处，所述升降抵挡装置还包括用于控制升降柱滑动的控制机构。当车辆撞击缓冲柱时，升降柱上移至缓冲柱的上方，进而提高防撞护栏的防护高度，使得车辆在升降柱的作用下难以发生侧翻，以对车辆和驾驶员起到保护作用。
