Reverse traction pier top swivel structure and construction method
The invention discloses a reverse traction pier top swivel structure and a construction method, and belongs to the technical field of bridge swivel. The turntable is fixedly mounted at the bottom center of the bridge; the beam bottom slideway is fixedly mounted on the bottom surface of the bridge; the drum is fixedly mounted on the bottom surface of the bridge; the two tensioning platforms are symmetrically arranged around the center of the bottom of the bridge; the tensioning platform is fixedly mounted at the edge of the bottom surface of the bridge; the inverted supporting feet are poured on the top face of the main pier. The inverted supporting leg is arranged below the beam bottom slideway; the spherical hinge assembly is poured in the center of the top face of the main pier. The bottom of the rotary disc is installed on the spherical hinge assembly. The anchoring legs are connected with the tensioning platform through traction cables, and the traction cables are arranged around the rotating drum; the anchoring legs are poured on the edge of the top face of the main pier. Torque is provided for a bridge through a top tensioning platform installed at the bottom of the bridge and a traction cable anchored between pier top legs, and a main beam is rotated to a designed position through a spherical hinge structure in the center of the top of a main pier; the rotating process is high in stability and low in cost.
本发明公开一种反向牵引墩顶转体结构及施工方法，属于桥梁转体技术领域，包括主墩和桥梁；转盘固定安装在桥梁底面中心；梁底滑道固定安装在桥梁底面；转筒固定安装于桥梁底面；张拉平台设置有两个，且绕桥梁底部中心中心对称设置；张拉平台固定安装在桥梁底面边缘处；倒置撑脚浇筑于主墩顶面；倒置撑脚设置于梁底滑道下方；球铰组件浇筑于主墩顶面中心，转盘底部安装在球铰组件上；锚固腿与张拉平台之间通过牵引索连接，牵引索绕转筒设置；锚固腿浇筑于主墩顶面边缘处。本发明通过安装在桥梁底部顶张平台和锚固在墩顶腿之间的牵引索为桥梁提供扭矩，通过主墩顶部中心位置的球铰结构将主梁旋转到设计位置；转体过程稳定性高，成本低。
