水电站厂房蜗壳混凝土浇筑具有体型复杂、专业交叉干扰多、蜗壳安装精度要求高、混凝土振捣困难等特点，是电站厂房最为复杂的施工部位，质量控制难度大。详细论述了向家坝水电站蜗壳混凝土的施工特点、主要施工程序和质量控制措施。向家坝左岸电站厂房施工主要通过防止蜗壳抬动变形、保证浇筑密实、控制混凝土最高温升等一系列措施，保证了目前国内最大发电机组蜗壳混凝土的浇筑质量，施工质量满足要求，可供其它工程借鉴。
水電站廠房蝸殼混凝土澆築具有體型複雜、專業交扠榦擾多、蝸殼安裝精度要求高、混凝土振擣睏難等特點，是電站廠房最為複雜的施工部位，質量控製難度大。詳細論述瞭嚮傢壩水電站蝸殼混凝土的施工特點、主要施工程序和質量控製措施。嚮傢壩左岸電站廠房施工主要通過防止蝸殼抬動變形、保證澆築密實、控製混凝土最高溫升等一繫列措施，保證瞭目前國內最大髮電機組蝸殼混凝土的澆築質量，施工質量滿足要求，可供其它工程藉鑒。

The concrete placement of the spiral case of a hydropower house is challenged by several difficulties such as compli -cated shape , interference of multi -constructions intersection , strict requirement of assembling accuracy and difficult concrete vi-bration, so its construction is the most complicated in power house construction .We give a detail presentation to the construction characteristics , main procedures and quality control measures in the spiral case construction of Xiangjiaba Hydropower Station . Through a series of controlling measures , including preventing the lifting deformation , ensuring grouting compactness and control-ling temperature rise, we guaranteed the construction quality of the largest spiral case in China .
