摘　　要：水利发电工程中,蜗壳作为水轮发电机组的重要组成部分,提高和保证蜗壳二期混凝土施工质量更是关系到水轮机组整体质量,也为后期发电运行提供有利的保证。以实际水利工程为案例,分析施工重难点,分层分块研究蜗壳二期混凝土施工工艺及质量控制。通过实例研究,优化二期混凝土浇筑工艺,提高了混凝土浇筑施工质量,对控制水轮机蜗壳二期混凝土施工质量质量有所提高。Volute is an important part of hydraulic power plant.The improvement and guarantee of concrete construction quality of volute second-stage concrete is related to the overall quality of hydraulic turbine unit,and also provides favorable guarantee for later power generation operation.Taking actual water conservancy project as an example,this paper analyses construction difficulties and difficulties,and studies construction technology and quality control of volute second-stage concrete by layers and blocks.Through case study,the second-stage concrete pouring process is optimized,the concrete pouring construction quality is improved,and the quality of controlling the second-stage concrete construction of turbine volute is improved.
