Rapid combined deviation correction system and method for bridge pier
The invention discloses a bridge pier rapid combined deviation correction system and method. Comprising the following steps: S1, detecting the slope rate of a bridge pier and the deviation distance of a support, and determining a deviation-rectifying displacement value; s2, a counter-force pile is newly added in the deviation rectifying direction of the original bridge pier, and a counter-force device, a hoop device and a steel structure opposite-pulling device are installed; s3, a plurality of vertical jacks are controlled by a jacking control system to synchronously jack the upper structure, and after a polyfluortetraethylene plate is installed at the position of an original support, a beam is dropped; s4, a horizontal jack is controlled by a pushing control system to push the side face of the pier in the deviation rectifying direction, and pushing is stopped when a support is reset or the strain epsilon of pier bottom concrete reaches an early warning value epsilon max; s5, releasing the stress at the bottom of the pier; and S6, the superstructure is jacked through a vertical jack, the polytetrafluoroethylene sliding plate is dismantled, a new support is replaced, a limiting device is installed on the superstructure of the bridge, and a steel structure opposite-pulling device is fixedly connected. The method has the advantages of being simple, convenient, safe and rapid in deviation rectification, and can be widely applied to the technical field of bridge support deviation rectification.
本发明公开了一种桥墩快速联合纠偏系统及方法。包括：S1，检测桥墩倾斜率与支座偏位距离，确定纠偏的位移值；S2，在原桥墩纠偏方向上新增反力桩，安装反力装置、抱箍装置、钢结构对拉装置；S3，通过顶升控制系统控制多个竖向千斤顶将上部结构同步顶升，在原有支座位置上安装聚四氟乙烯板板后落梁；S4，通过顶推控制系统控制水平千斤顶沿纠偏方向顶推桥墩侧面，当支座复位或墩底混凝土应变ε达到预警值εmax时停止顶推；S5，墩底应力释放；S6，通过竖向千斤顶顶升上部结构，拆除四氟滑板，更换新支座，在桥梁上部结构安装限位装置并固结钢结构对拉装置。本发明具有简便、安全、快速纠偏的优点，可广泛应用于桥梁支座纠偏技术领域。
