Anti-collision and energy-dissipation device for segment-assembled pier and splicing method of anti-collision and energy-dissipation device
The invention relates to an anti-collision energy dissipation device for a segment assembled pier and a splicing method of the anti-collision energy dissipation device, belongs to the field of anti-collision devices for bridge engineering, and solves the problem that an assembled pier in the prior art is poor in anti-collision capability and anti-shearing capability. The anti-collision energy dissipation device for the segment-assembled pier comprises an anti-shearing steel plate, an FRP lattice, an FRP shell and an anti-collision shell. The shear-resistant steel plate is installed on the two adjacent prefabricated piers, so that the shear-resistant steel plate can stretch across a splicing seam between the two prefabricated piers, and the FRP lattice, the FRP shell and the anti-collision shell are sequentially arranged on the face, away from the prefabricated piers, of the shear-resistant steel plate. The shear bearing capacity of the prefabricated bridge pier section position is improved, so that the shear damage of the prefabricated assembled bridge connecting section under the impact load is reduced, the shear displacement between the splicing seams is reduced, and the anti-collision performance and the safety of the bridge are improved.
本发明涉及一种节段拼装桥墩抗撞消能装置及其拼接方法，属于桥梁工程抗撞装置领域，解决了现有技术中拼装桥墩抗撞能力以及抗剪能力差的问题。一种节段拼装桥墩抗撞消能装置包括抗剪钢板、FRP格构、FRP外壳和抗撞外壳；抗剪钢板安装于相邻的两个预制桥墩上，使得抗剪钢板能够横跨两个预制桥墩之间的拼接缝，抗剪钢板远离预制桥墩的一面依次设置有FRP格构、FRP外壳和抗撞外壳。本发明提高了预制桥墩节段位置的抗剪承载力，从而减小在撞击荷载下的预制拼装桥梁连接节段的剪切损伤，降低了拼接缝间的剪切位移，提高了桥梁的抗撞性能和安全性。
