Vehicle collision prevention device for bridge pier
The invention discloses a pier vehicle collision prevention device which comprises a bionic honeycomb column thin-wall structure arranged on a pier and a collision prevention structure arranged on the bionic honeycomb column thin-wall structure. The anti-collision structure comprises a panel, a restraint plate arranged in the circumferential direction of the panel and forming a closed loop, shear nails arranged in the panel and rib plates arranged on the inner wall of the restraint plate and extending into the panel. The panel comprises the rib plates and the shear nails, so that the interface bonding force between the ultra-high-performance concrete panel and the constraint plate is enhanced, the ultra-high-performance concrete panel and the constraint plate are tightly combined together, the ultra-high-performance concrete anti-collision structure and the bionic honeycomb column thin-wall structure are combined together, and the ultra-high-performance concrete-bionic honeycomb column thin-wall combined structure is formed. Kinetic energy of vehicles can be efficiently absorbed to resist vehicle collision, the damage degree of the bridge pier is relieved, the normal use performance of a bridge is guaranteed, and the problems that an existing anti-collision structure is low in protection efficiency, prone to local damage and poor in reusability are creatively solved.
本发明公开了一种桥墩防车辆撞击装置，包括设置在桥墩上的仿生蜂窝柱薄壁结构和设置在仿生蜂窝柱薄壁结构上的防撞结构，防撞结构包括面板、设置在所述面板周向上并形成闭环的约束板、设置在所述面板内部的剪力钉以及设置在所述约束板内壁上并延伸至所述面板内部的肋板；本发明的面板中含有肋板和剪力钉增强超高性能混凝土面板与约束板的界面粘结力，使其紧密结合在一起，将超高性能混凝土防撞结构和仿生蜂窝柱薄壁结构组合在一起，形成超高性能混凝土‑仿生蜂窝柱薄壁组合结构，可以高效的吸收车辆动能抵御车辆撞击，减缓桥墩的损伤程度，保障桥梁的正常使用性能，创造性解决现有防撞结构防护效率低、易发生局部损伤、重复使用性差的问题。
