Fabricated pier-bearing platform mechanical connection structure and connection method
The invention provides a mechanical connection structure and method for an assembled pier-bearing platform, and belongs to the technical field of bridge prefabrication and assembly construction. Aiming at the problems of high rigidity, low ductility and the like caused by the fact that a grouting sleeve is adopted for an existing assembly type bridge pier and a bearing platform, the connecting structure comprises a bearing platform foundation and a prefabricated bridge pier located above the bearing platform foundation, an annular groove is formed in the upper surface of the bearing platform foundation, and the prefabricated bridge pier is erected at the top of the annular groove and connected with the bearing platform foundation through a sleeving assembly; a concrete frustum is arranged from a cavity of the annular groove to the top of the bearing platform foundation, and the concrete frustum is arranged outside the prefabricated pier in a wrapping mode. According to the connection of the prefabricated pier and the bearing platform foundation, the earthquake dissipation capacity and durability of the prefabricated pier can be improved, the construction process is simplified, and the construction safety risk and the later repair difficulty can be effectively reduced while the engineering construction quality and the construction period progress are ensured.
本发明提供一种装配式桥墩‑承台的机械连接结构及连接方法，属于桥梁预制拼装施工技术领域。针对目前装配式桥墩与承台采用灌浆套筒存在的刚度大、延性低等问题，本发明的连接结构包括承台基础和位于其上方的预制桥墩，承台基础的上表面开设环形凹槽，预制桥墩架设于环形凹槽的顶部并与承台基础通过套接组件相连接，自环形凹槽的空腔至承台基础的顶部设置混凝土锥台，且混凝土锥台包裹式设置在预制桥墩的外部。本发明的预制桥墩与承台基础的连接能够提高预制桥墩的地震耗散能力及耐久性，简化施工工艺，在确保工程施工质量与工期进度的同时，可有效减小施工安全风险以及后期修复难度。
