苏阿皮蒂电站混流式水轮机组尾水肘管安装要点

Installation Key Points of the Draft Tube Elbow of Francis Turbine Units in Souapiti Hydropower Station

根据苏阿皮蒂电站混流式水轮机尾水肘管的结构特点,分析安装过程中容易出现的问题,制定了合理的安装要点。在肘管钢衬运输至工地后,利用提前搭设的组装平台将分瓣的钢衬分段拼接,再运至现场完成分段肘管整体组装焊接与检测工作。由于施工准备充分,配置资源齐全,施工组织严密,施工过程监控得力,保障了肘管优良的安装质量。

Considering the structural characteristics of the draft tube elbow of Francis turbine units in Souapiti Hydropower Station,the noticeable issues in the elbow installation process are discussed and the key points of the installation are determined.After the steel linings of the elbow are transported to the construction site,the split linings are assembled in segments using the assembly platform built in advance,and then transported to the site to complete the whole welding assembly and examination work.With the adequate construction preparation,abundant resources allocation,tight construction organization,and effective monitoring of the construction process,the quality of the elbow installation is ensured.
