The invention provides a novel prefabricated assembled pier, and relates to the field of bridge engineering. The novel prefabricated assembled pier comprises a bearing platform and prefabricated piersections, the prefabricated pier sections are arranged at the top of the bearing platform; prestressed tendons are arranged in the prefabricated pier sections; the prestressed tendons are bonded withthe prefabricated pier sections in a pouring manner; a steel plate is arranged in the bearing platform, the prestressed tendons are connected with the steel plate in a bound mode, the steel plate andthe bearing platform are bonded through concrete pouring, a T-shaped first connecting steel component is arranged in each prefabricated pier section, and one end of the first connecting steel component penetrates through the prefabricated pier section and extends out of the prefabricated pier section. According to the novel prefabricated assembled pier, energy dissipation is generated through extrusion of the outer sides of the high-strength bolts, the allowance holes and the limiting insertion holes, the earthquake effect of the prefabricated pier sections is reduced, the high-strength boltscan be detached and reinstalled, good recoverability after an earthquake is achieved, and normal use after the earthquake is not affected.
本发明提供一种新型预制拼装桥墩，涉及桥梁工程领域。该新型预制拼装桥墩包括承台和预制桥墩节段，预制桥墩节段设在承台顶部，预制桥墩节段内部设有预应力筋，预应力筋与预制桥墩节段浇筑粘接，承台内部设有钢板，预应力筋与钢板捆绑连接，钢板与承台通过混凝土浇筑粘接，预制桥墩节段内部设有第一连接钢构件，第一连接钢构件设置为T字形，第一连接钢构件一端穿过预制桥墩节段延伸至预制桥墩节段外部。该新型预制拼装桥墩通过高强螺栓外侧与余量孔和限制插孔的挤压均产生能量耗散，减轻预制桥墩节段的地震作用，高强螺栓可以拆除和重新安装，具有很好的震后可恢复性，不影响震后的正常使用。
