Pile foundation underpinning structure combined with subway station structure
The invention belongs to the technical field of pile foundation underpinning, and discloses a pile foundation underpinning structure combined with a subway station structure, the pile foundation underpinning structure comprises a pile foundation, an underpinning pile, a connecting column and an underpinning beam, the pile foundation serves as the foundation of the pile foundation underpinning structure and the subway station structure, the underpinning pile is provided with an arc-shaped groove, the connecting column is provided with an arc-shaped protrusion, and the underpinning beam is provided with an underpinning groove. A damping equipment elastic steel plate is arranged between the arc-shaped groove and the arc-shaped protrusion, the connecting column and the underpinning pile are connected through an adjusting assembly, the top of the connecting column is connected with the lower portion of the underpinning beam, the top of the underpinning beam is connected with an existing bridge pile foundation, the underpinning pile is arranged in an underpinning foundation pit in a penetrating mode, and the adjusting assembly is arranged in the underpinning foundation pit. The pile foundation underpinning structure and the subway station structure are combined and synchronously implemented and jointly stressed, the construction procedure is simplified, the engineering cost is reduced, and the construction period is shortened; and the pile foundation underpinning structure is beneficial to leveling the bridge and avoiding resonance between the bridge and the subway station.
本发明属于桩基托换技术领域，公开了一种与地铁车站结构相结合的桩基托换结构，包括桩基基础、托换桩、连接柱和托换梁，桩基基础同时作为桩基托换结构和地铁车站结构的基础，托换桩设有弧形凹槽，连接柱设有弧形凸起，弧形凹槽与弧形凸起之间设有减震设备弹性钢板，连接柱与托换桩之间通过调节组件连接，连接柱的顶部与托换梁的下部连接，托换梁的顶部与既有的桥梁桩基连接，托换桩穿设于托换基坑，调节组件设于托换基坑内；本发明将桩基托换结构与地铁车站结构相结合，同步实施，共同受力，简化施工工序，降低工程成本，节省工期；而且该桩基托换结构对于桥梁的校平、避免桥梁与地铁站的共振均有益。
