摘　　要：采用吊罐法对厚50cm左右、最小面积5～10m2的水下不分散混凝土修补工程进行施工,在国内鲜有报道。通过漫湾电站C40水下不分散混凝土工程实例,介绍了C40水下不分散混凝土修补材料的配比、施工工艺和技术要点。实践表明:用C40水下不分散混凝土代替聚合物混凝土施工,降低了工程造价,保证了工程质量。对类似的水下混凝土工程的施工,具有很好的指导意义。It is the rare case being reported at home to use anti-washout underwater concrete in reparation construction. This paper introduces the mix proportion of reparation materials, construction process and technological points of C40 anti-washout underwater concrete through the engineering example of Manwan Power Station. The practice shows that the substitution of C40 anti-washout underwater concrete for polymer concrete will reduce engineering cost and ensure engineering quality. It provides a good guidance for similar anti-washout underwater concrete projects.
