Hollow bridge pier structure capable of achieving modular prefabricated segment assembly and self-resetting
The invention discloses a hollow bridge pier structure capable of achieving modular prefabricated segment assembly and self-resetting, and relates to the technical field of bridge engineering, the hollow bridge pier structure comprises a bearing platform, a bridge pier segment and an upper segment which are sequentially stacked from bottom to top, and the bridge pier segment and the upper segment are hollow cylinders with square annular sections; each pier section comprises three types of prefabricated modules, and the three types of prefabricated modules are spliced to form a plurality of section layers with the same specification; the prefabricated modules located in the same segment layer are meshed with one another in a mortise and tenon joint mode, and every two vertically adjacent segment layers rotate by 90 degrees along the central axis of the hollow cylinder and then are stacked. Every two vertically-adjacent segment layers, the segment layers and the bearing platform, and the upper segment and the segment layers are longitudinally connected through main reinforcing steel bars, prestressed reinforcing steel bars and separated prefabricated reinforcing steel bar shear keys. Based on the concept of block stacking, the construction method has the advantages of being convenient to transport, small in environmental influence, high in construction speed and capable of reducing the engineering cost.
本申请公开了一种可实现模块化预制节段拼装且自复位的空心桥墩结构，涉及桥梁工程技术领域，包括由下至上依次堆叠的承台、桥墩节段和上部节段，所述桥墩节段和上部节段均为截面呈方形环状的空心柱体；且所述桥墩节段包括三种类型的预制模块，三种类型的预制模块拼接构成多层规格一致的节段层；位于同一所述节段层中的各个预制模块之间通过榫卯连接的方式相互咬合，上下相邻的两层节段层沿空心柱体中轴线旋转90°后堆叠；上下相邻的两层节段层之间、节段层和承台之间、上部节段和节段层之间通过钢筋主筋、预应力钢筋和分离式的预制钢筋剪力键纵向连接。本申请基于块体堆叠的概念，具有运输方便、环境影响小、施工速度快、降低工程成本的优势。
