Anti-collision guardrail with buffering function for expressway bridge
The invention discloses an anti-collision guardrail with a buffering function for an expressway bridge, which comprises two guardrail upright posts, a plurality of anti-collision beams and a plurality of anti-collision beams, the upper ends of the two guardrail upright posts are fixedly connected with each other through a reinforcing cross rod, and the upper ends of the two guardrail upright posts are fixedly connected with each other through the reinforcing cross rod; a speed reduction table which is installed at the front end of the lower surface of the guardrail stand column, and the speed reduction table is connected with the guardrail stand column in a welded mode; and resistance strain gauge collision sensors which are mounted at the front end of the speed reduction table, and the number of the resistance strain gauge collision sensors is four. According to the anti-collision guardrail, the airbag storage box is additionally arranged on the guardrail, after a vehicle is impacted, the sensor can receive a signal in time, the inflation system is ignited, the airbag is popped out of the airbag storage box and covers the front end of the guardrail, the flexible buffering effect is achieved, and therefore the situation that an existing anti-collision guardrail is integrally of a steel structure, and when the vehicle is accidentally impacted, the buffering effect is poor, and damage to a driver cannot be relieved.
本发明公开了一种高速公路桥梁用具有缓冲功能的防撞护栏，包括：护栏立柱，所述护栏立柱设置有两个，且两个所述护栏立柱的上端通过加固横杆固定连接；减速台，其安装在所述护栏立柱下表面的前端，且减速台与护栏立柱焊接连接；电阻应变计碰撞传感器，其安装在所述减速台的前端，所述电阻应变计碰撞传感器设置有四个。其实现了在护栏上增设气囊收纳盒，当车辆冲击后，传感器能够及时接收到信号，点燃充气系统，使气囊从气囊收纳盒内弹出，覆盖于护栏前端，起到柔性缓冲的作用，从而有效的避免了现有的防撞护栏整体采用钢制结构，遭遇车辆意外撞击时，缓冲效果不佳，无法减缓驾驶员所受损伤的问题。
