摘　　要：文章以大化水电站扩建工程机组的座环支撑螺杆现场安装为例,介绍了水轮机座环支撑螺杆取消预留孔三期混凝土浇筑,在二期混凝土浇筑前先行安装固定好,与二期混凝土同时浇筑的方法。该安装方法减少了模板的工程量,也减少了上下交叉作业的时间,加快了工程的进度。The paper makes an introduction to the installation method of turbine stay ring support bolt based on Dahua hydropower station extension project,in which the support bolts are fixed before the second-stage concrete and poured together with the second-stage concrete so that the third-stage concrete can be cancelled. The method not only reduces the quality of concrete form, shortens the time of crossover work,but also speeds up the project progress.
