Bridge pier anti-collision device on width-limited central separating strip
The invention discloses a bridge pier anti-collision device on a width-limited central separating strip. The bridge pier anti-collision device comprises a steel guardrail and concrete guardrails of the medial strip, the concrete guardrails are located at the two ends of a bridge pier, each concrete guardrail comprises a head-on collision face section, a transition section and a rectangular section, the width of the transition section is gradually increased in the direction from the concrete guardrails to the bridge pier, the small end of the transition section is connected with the head-on collision face section, the large end of the transition section is connected with one end of the rectangular section, and the other end of the rectangular section is detachably connected with the pier steel guardrail. The transition section facilitates vehicle resetting, and the probability that the vehicle collides with the part, higher than the guardrail, of the medial strip pier is reduced; the bridge pier steel guardrail adopts a steel structure with a reinforced back, so that the bridge pier can be protected, and meanwhile, vehicles are prevented from being damaged. And the concrete guardrail is detachably connected with the bridge pier steel guardrail, so that the bridge pier steel guardrail can be conveniently dismounted and replaced after being damaged, the repairing time and cost are saved, the safety risk of recovering central separation strip collision of a locally closed road is reduced, and smooth driving is ensured.
本发明公开了一种处于宽度受限中央分隔带上的桥墩防撞装置，包括钢护栏和中央分隔带的混凝土护栏，混凝土护栏位于桥墩的两端，混凝土护栏包括迎撞面段、过渡段和矩形段，过渡段的宽度自混凝土护栏朝向桥墩的方向逐渐增大，且过渡段的小端与迎撞面段连接，过渡段的大端与矩形段的一端连接，矩形段的另一端与桥墩钢护栏可拆卸连接。本发明的过渡段有利于车辆复位，并减小车辆撞击中央分隔带桥墩高出护栏部分的概率；本发明的桥墩钢护栏采用背后加劲的钢结构，可以保护桥墩，同时避免车辆受损。混凝土护栏与桥墩钢护栏可拆卸连接，便于桥墩钢护栏损坏后拆除更换，节约修复时间和成本，降低局部封闭道路恢复中央分隔带防撞的安全风险，保证行车通畅。
