Bridge pier anti-collision device with GFRP wrapped with foamed aluminum
The invention belongs to the field of civil engineering, and particularly relates to a bridge pier anti-collision device with GFRP wrapped with foamed aluminum. The anti-collision device is composed of a plurality of spliced anti-collision blocks arranged on the periphery of the bottom of the concrete pier, and each anti-collision block of the anti-collision device composed of the anti-collision blocks comprises a GFRP hollow sleeve box, a cover plate matched with the GFRP hollow sleeve box and foamed aluminum assembled in the GFRP hollow sleeve box through a shell body pipe self-tightening technology. After assembly, the GFRP hollow sleeve box exerts prestress on the foamed aluminum, and centripetal constraint on the foamed aluminum is achieved. The GFRP shell hollow sleeve box is used for forming a flexible framework to restrain and integrally and cooperatively deform the sandwich foamed aluminum material in the flexible framework, vehicle impact energy can be effectively dispersed, meanwhile, the modular design thought is applied, material loss is reduced, manufacturing is easy, carrying is convenient, assembling is rapid, partial replacement and repair can be achieved when the device is damaged, and the service life of the device is prolonged. The invention is applied to land circular bridge pier columns with vehicle collision prevention requirements.
本发明属于土木工程领域，具体涉及一种GFRP外包泡沫铝的桥墩防撞装置。防撞装置由设置在混凝土桥墩底部外周的多个拼装的防撞块组成，防撞块组成的防撞装置为每一个防撞块包括GFRP空心套箱，与GFRP空心套箱相配合的盖板以及通过外壳身管自紧技术装配在GFRP空心套箱内的泡沫铝；装配后GFRP空心套箱对泡沫铝施加预应力、且实现对泡沫铝的向心约束。本发明利用GFRP外壳空心套箱构成柔性骨架对内部的夹芯泡沫铝材料进行约束，整体协同变形，可有效分散车辆撞击能量，同时运用模块化设计思路，减少材料损耗，制作简单，搬运方便，组装快速，且在遭受破坏时可部分更换修复，本发明应用于有防车辆撞击要求的陆上圆形桥梁墩柱。
