Height-limited narrow terrain damaged pier underpinning construction method
The invention discloses an underpinning construction method for a height-limited narrow terrain damaged pier. The underpinning construction method comprises the following steps that S1, a temporary supporting structure used for transferring bearing force of a bridge is built; s2, the temporary supporting structure is used for jacking up the bridge, the bridge load is completely transferred to the temporary supporting structure from the original bridge pier, and at the moment, the original bridge pier is not stressed; s3, a bridge pier underpinning structure is built according to the terrain, the bridge pier underpinning structure comprises a new pile foundation and a new bearing platform, and the bridge pier underpinning structure is used for providing support for the bridge, so that the damaged original bridge pier is not subjected to the pressure of the bridge; and S4, the temporary supporting structure is dismantled, and the load of the bridge is gradually transferred to the new bearing platform from the temporary supporting structure. The method has the effect of improving the safety of the height-limited narrow terrain bridge.
本申请公开了一种限高窄地势破损桥墩托换施工方法,其包括如下步骤：S1：搭建用于将桥梁承力转移的临时支撑结构；S2：使用临时支撑结构将桥梁顶起，使桥梁荷载从原桥墩全部转移到临时支撑结构，此时原桥墩不受力；S3：根据地势建设桥墩托换结构，桥墩托换结构包括新桩基和新承重台，桥墩托换结构用于为桥梁提供支撑，使破损的原桥墩不受桥梁的压力；S4：拆除临时支撑结构，使桥梁的荷载从临时支撑结构逐渐转移到新承重台。本申请具有提高限高窄地势的桥梁安全性的效果。
