堆石混凝土技术在水库除险加固工程中的应用

Application of Rock-fill Concrete Technology in Reservoir Reinforcement Project

堆石混凝土技术是由清华大学水利水电工程系发明并获得国家发明专利授权的新型大体积混凝土施工技术,其技术特征是利用专用自密实混凝土充填堆石空隙形成完整密实的混凝土,具有低碳环保、低水化热、工艺简便、造价低廉、施工速度快等特点。通过在水沟口二库坝体培厚加固工程中的应用,其先进特点得到有效利用。

Rock-fill concrete technology was invented by the Department of Hydraulic Engineering of Tsinghua University and got a patent awarded by the state. Its technical characteristic is to use a dedicated self-compacting concrete to fill rock-fill gap and form a complete compacting concrete which is low carbon, low heat of hydration, the simple process, low cost, rapid construction speed and other features. In the application in reinforcement engineering of No.2 reservoir at Shuigoukou, its advantages are reflected.
