Water turbine volute internal corner backfill grouting auxiliary structure and backfill grouting method
The invention discloses a water turbine volute internal corner backfill grouting auxiliary structure and a backfill grouting method. The inner side of a seat ring is fully used as a construction space, arrangement of grouting pipelines is optimized, the arrangement work of the grouting pipelines is reduced, the grouting difficulty is reduced, and meanwhile the influence on other equipment pipelines, steel bars and concrete pouring construction is reduced. The structure comprises temporary supporting seats, inner side formworks and grouting pipes, the multiple temporary supporting seats and the multiple inner side formworks are arranged below a seat ring in a surrounding mode, and the inner side formworks are vertically arranged on the inner sides of the temporary supporting seats; the grouting pipe sequentially penetrates through the inner side formwork and the gap between the adjacent temporary supporting seats from the inner side of the seat ring and extends to the internal corner part of the volute. The method comprises the steps that the inner side formwork is installed on the inner side of the temporary supporting base; a hole is formed in the inner side formwork to install a grouting pipe; an exhaust pipe is upwards connected to the seat ring exhaust hole; backfill grouting is conducted on the volute internal corner part 6 through a grouting pipe; and cutting off the exposed parts of the grouting pipeline and the exhaust pipe.
本发明公开了一种水轮机蜗壳阴角回填灌浆辅助结构及回填灌浆方法，充分利用座环内侧作为施工空间，优化灌浆管路的布置，减少灌浆管布置工作，降低灌浆难度，同时减少对其他设备管路、钢筋以及混凝土浇筑施工的影响。所述结构包括临时支撑座、内侧模板和灌浆管，环绕座环的下方设置若干临时支撑座和内侧模板，所述内侧模板竖直布置于临时支撑座的内侧，所述的灌浆管自座环的内侧依次穿过内侧模板和相邻临时支撑座之间空隙延伸至蜗壳阴角部分。所述方法步骤包括在临时支撑座内侧安装内侧模板；在内侧模板开孔安装灌浆管；在座环排气孔位置向上接引排气管；通过灌浆管对蜗壳阴角部分6进行回填灌浆；对灌浆管路与排气管外露部分进行割除。
