Quick repair method for damaged bridge pier
The invention provides a method for quickly repairing a damaged bridge pier, which comprises the following steps of: S10, straightening a pier column; s20, a preset area is selected on a bearing platform corresponding to the pier column, the preset area is located on the periphery of the pier column, reinforcing ribs are implanted into the preset area, and the extending path of the reinforcing ribs is parallel to the axial direction of the pier column; and S30, a formwork is built on the periphery of the pier column, the reinforcing ribs are located in the formwork, high-performance concrete is poured into the formwork, and a reinforcing section is formed after the high-performance concrete is solidified. According to the rapid repairing method for the damaged pier, reinforcing ribs are not arranged in the pier column, limitation of operation space is avoided, the repairing technology is simplified, the construction speed is effectively increased, and the repairing time is saved; the high-performance concrete used in the reinforcing section has the restraining effect of replacing stirrups on the pier column core area, and the shear capacity, the ductility and the anti-seismic performance of the repaired pier column are guaranteed.
本发明提供了一种受损桥墩快速修复方法，所述受损桥墩快速修复方法包括如下步骤，S10：对墩柱进行扶直；S20：在所述墩柱对应的承台上选取预设区域，所述预设区域位于所述墩柱的外周，在所述预设区域内植入加固筋，所述加固筋的延伸路径平行于所述墩柱的轴向；S30：在所述墩柱的外周搭建模板，所述加固筋处于所述模板内，并向所述模板内浇注高性能混凝土，所述高性能混凝土固结后形成加固段。本发明提供的受损桥墩快速修复方法并不在墩柱内设置加固筋，不受操作空间限制，简化了修复技术，进而有效提高施工速度，节省修复时间；加固段所用高性能混凝土对墩柱核心区具有替代箍筋的约束作用，保证了修复后墩柱的抗剪能力、延性、抗震性能。
