水轮发电机组转轮室拆除施工方法,包括以下步骤:S1:在转轮室下方的尾水管锥管内安装承重平台;S2:将升降平台拼装好后吊装放置到承重平台上;S3:在承重平台中部安装升降钢架,S4:吊入高压水射流设备;S5:在座环上法兰面上安装上层结构盖板;S6:转轮室拆除,同步进行高压水射流设备的组装。本发明综合了人工拆除技术和高压水射流技术,将转轮室划分三个层次,根据各个拆除单元、单位、对象之间的相互约束关系分别提出各层次按照不同技术分解拆除的各个步骤,大大减少了施工工期,满足了人员通行的需求,保障了现场作业安装,对大体积大尺寸转轮室拆除具体实施具有指导作用。

    The water-turbine generator set runner chamber dismantling construction method comprises the following steps that S1, a bearing platform is installed in a draft tube taper pipe below a runner chamber; s2, after being assembled, the lifting platform is hoisted and placed on the bearing platform; s3, mounting a lifting steel frame in the middle of the bearing platform; S4, hoisting high-pressure water jet equipment; s5, an upper-layer structure cover plate is installed on the upper flange face of the seat ring; and S6, the runner chamber is disassembled, and the high-pressure water jet equipment is assembled synchronously. According to the method, the manual dismantling technology and the high-pressure water jet technology are integrated, the runner chamber is divided into three layers, all the steps of decomposition and dismantling of all the layers according to different technologies are provided according to the mutual constraint relation among all dismantling units, units and objects, the construction period is greatly shortened, the passing requirement of personnel is met, and the construction efficiency is improved. Field operation and installation are guaranteed, and a guiding effect is achieved on specific implementation of dismantling of the large-size runner chamber.
