Pile foundation structure utilizing existing open caisson
The pile foundation structure utilizing the existing open caisson comprises the existing open caisson and further comprises a pile foundation, a bearing platform and a supporting assembly, and the pile foundation is arranged outside the side wall of the existing open caisson in a surrounding mode; the bearing platform is arranged at the top end of the pile foundation, and the bottom elevation of the bearing platform is higher than that of the existing open caisson; the supporting assembly is arranged between the bearing platform and the existing open caisson, and the bearing platform is in sliding connection with the existing open caisson through the supporting assembly. According to the pile foundation structure, the pile foundations are arranged on the periphery of the existing open caisson, the existing open caisson and the newly-built bearing platform are in sliding connection through the supporting assembly, the vertical bearing capacity of the existing open caisson is effectively exerted, and the horizontal stress characteristic of the pile foundation structure is simplified by releasing the horizontal constraint of the existing open caisson on the bearing platform; reasonable utilization of the existing old open caisson foundation is achieved, the foundation scale and the engineering amount of a newly-built bridge can be effectively reduced, and the engineering cost is reasonably controlled.
本申请涉及一种利用既有沉井的桩基础结构，包括既有沉井，桩基础结构还包括：桩基、承台和支撑组件，桩基环绕设置于既有沉井侧壁外；承台设置于桩基顶端，且承台底面高程高于既有沉井顶面高程；支撑组件设置于承台与既有沉井之间，且承台通过支撑组件与既有沉井滑动连接。本发明中，在既有沉井周边布置桩基，并使既有沉井与新建承台之间通过支撑组件变为滑动连接，不仅有效发挥了既有沉井的竖向承载力，还通过释放既有沉井对承台的水平约束简化了桩基础结构的水平受力特性，实现了既有老旧沉井基础的合理利用，可有效减少新建桥梁的基础规模与工程量，合理控制工程成本。
