在水利水电工程中,混凝土牛腿是一种常见的结构。由于牛腿的特殊体形及布置,其施工难度及施工安全威胁都比较大。采用预制钢筋混凝土模板代替传统的组合钢模板,可使施工更加安全、方便,不仅有效加快施工进度,还可节约施工成本。该文就景洪电站右岸导流缺口坝段牛腿混凝土的施工,详细介绍了牛腿预制钢筋混凝土模板的设计及施工。 In the water conservancy and hydropower projects, concrete is a common structure of the cow. Due to the special shape and layout of the cow legs, the construction difficulty and the construction safety threat are relatively large. The use of precast reinforced concrete formwork instead of the traditional composite steel formwork can make the construction more safe and convenient, which not only speeds up the construction progress effectively, but also saves the construction cost. This paper introduces the design and construction of the corbels’ prefabricated reinforced concrete formwork on the concrete construction of the diversion gap at the right bank of Jinghong Hydropower Station.
