Passive underpinning construction method for rigid framework thin-wall pier
The invention relates to a passive underpinning construction method for a rigid frame thin-wall pier. The passive underpinning construction method comprises the following steps that S1, the bottom of an enlarged foundation of the rigid frame thin-wall pier is reinforced; s2, underpinning pile construction; s3, excavation of a foundation pit; s4, an emergency safety support is installed; s5, steel bars are planted in the rigid framework thin-wall pier; s6, underpinning beam construction; s7, grouting reinforcement is conducted on the bottom of the underpinned pile; and S8, grouting reinforcement is conducted on the periphery of the underpinning pile. The passive underpinning construction is simple, the single construction period is short, and the application of the passive underpinning method in the continuous beam bridge pile foundation underpinning project is expanded.
本申请涉及一种刚构薄壁墩被动托换施工方法，包括如下步骤：S1：刚构薄壁墩的扩大基础底部加固；S2：托换桩施工；S3：基坑开挖；S4：安装应急安全支架；S5：对刚构薄壁墩植筋；S6：托换梁施工；S7：托换桩底注浆加固；S8：托换桩周边注浆加固。本申请被动托换施工简、单工期短，拓展了其在连续梁桥桩基托换工程中的应用。
