Synchronous construction method for straining beam and pier body in hydraulic creeping formwork high pier
The invention discloses a synchronous construction method for a middle straining beam and a pier body of a hydraulic creeping formwork high pier. The synchronous construction method comprises the following steps that S1, a creeping cone is pre-buried, specifically, the creeping cone is pre-buried in a circulation section pier body below the middle straining beam; s2, a circulation segment pier body adjacent to the lower portion of the middle straining beam is poured; s3, demolding and modifying a creeping formwork; s4, mounting a supporting bracket; s5, a middle straining beam bottom formwork is installed; s6, the climbing component for blocking the climbing formwork is dismounted; s7, a pier body and a middle straining beam steel bar are bound on the middle straining beam bottom formwork and the remaining creeping formwork operation platform at the same time; s8, a middle straining beam side formwork is installed; s9, pouring the middle straining beam and pier body concrete corresponding to the height of the middle straining beam; s10, the formwork is dismantled; s11, tensioning and grouting prestressed tendons of the middle straining beam; s12, a climbing part in the detached climbing formwork is recovered, and two side panels and accessory parts of the climbing formwork are installed; and S13, a circular segment pier body adjacent to and above the middle straining beam is constructed.
本发明公开了一种液压爬模高墩中系梁与墩身同步施工工法，包括如下步骤：S1、预埋爬锥：在中系梁相邻下方一个循环节段墩身内预埋爬锥；S2、浇筑中系梁相邻下方一个循环节段墩身；S3、脱模并改装爬模；S4、安装支撑牛腿；S5、安装中系梁底模板；S6、拆除阻挡爬模的爬升部件；S7、在中系梁底模板和剩余爬模操作平台上同时绑扎墩身与中系梁钢筋；S8、安装中系梁侧模板；S9、浇筑中系梁和对应中系梁高度墩身混凝土；S10、拆除模板；S11、中系梁预应力筋张拉及压浆；S12、恢复拆除的爬模中爬升部件，将爬模两块侧面板及其附属配件安装好；S13、浇筑中系梁相邻上方一个循环节段墩身施工。
