Energy-absorbing anti-collision high-performance bridge pier
The invention discloses an energy-absorbing anti-collision high-performance bridge pier and the bridge pier comprises a concrete bridge pier body, a foamed aluminum layer, an FRP layer and a stainless steel layer. The foamed aluminum layer is pasted and fixed on the surface of the concrete pier through resin, the FRP layer is wound and wrapped on the surface of the foamed aluminum layer after fiber cloth is impregnated with resin, and the stainless steel layer is installed and fixed on the outer surface of the FRP layer through bolts or welding. The foamed aluminum layer absorbs impact energy through deformation, the FRP layer provides elastic restoring force, and the stainless steel layer provides certain rigidity. The bridge pier is scientific and reasonable in design thought, safe and reliable in material, good in durability and convenient and rapid to construct, normal use of the pier can be protected after small impact occurs, damage to concrete in the pier can be reduced after large impact occurs, and normal use can be rapidly recovered.
本发明公开了一种吸能防撞高性能桥墩，包括混凝土桥墩、泡沫铝层、FRP层和不锈钢层。泡沫铝层通过树脂粘贴固定于混凝土桥墩表面，FRP层由纤维布浸渍树脂后缠绕并包裹于泡沫铝层表面，不锈钢层通过螺栓或焊接安装固定于FRP层外表面。泡沫铝层通过变形吸收冲击能量，FRP层提供弹性恢复力，不锈钢层提供一定的刚度。本发明设计思路科学合理，材料安全可靠、耐久性好，施工方便快捷，在较小的撞击发生后可以保护桥墩正常使用，在较大的撞击发生后可以减小桥墩内部混凝土的损伤并快速恢复正常使用。
