A bridge lower structure and a foundation are sequentially provided with a cover beam, an upper segment bridge pier, a lower segment bridge pier, a bearing platform and a pile foundation from top to bottom, the cover beam and the upper segment bridge pier are connected through an upper connecting device, and the upper segment bridge pier and the lower segment bridge pier are connected through a segment connecting device. The upper connecting device is connected with the upper segment pier, the lower segment pier is connected with the bearing platform through the lower connecting device, the bearing platform and the pile foundation are cast into a whole in a cast-in-place mode, and the upper connecting device, the segment connecting device and the lower connecting device are each composed of an upper connecting part, a lower connecting part, an anchor rod and a nut. And the plastic hinge bridge pier can be replaced after an earthquake, and can be widely applied to quick construction and dismantling of bridges.
本发明公开了一种装配式可更换桥墩，桥梁下部结构与基础自上而下依次为盖梁、上节段桥墩、下节段桥墩、承台、桩基，所述盖梁与上节段桥墩之间采用上连接装置连接，所述上节段桥墩与下节段桥墩之间采用节段连接装置连接，所述下节段桥墩与承台之间采用下连接装置连接，所述承台与桩基现浇为整体，所述上连接装置、节段连接装置、下连接装置均由上连接件、下连接件、锚杆、螺母组成，本发明设计巧妙，既可实现装配式桥墩现场零浇筑，又可实现震后出现塑性铰桥墩的更换，可广泛应用于桥梁快速化建造与拆除。
