大坝碾压混凝土浇筑温控措施探讨

Discussion on Casting Temperature Control Measures for Roller Compacted Concrete of Dam

为防止大坝碾压混凝土浇筑出现有害性裂缝,采取优化混凝土配合比、降低入仓温度、通水冷却等温控措施,可确保碾压混凝土浇筑全过程具有良好的温控条件,使碾压混凝土施工质量满足设计要求,推动工程高效优质地完成。

In order to prevent harmful cracks during pouring process of dam roller compacted concrete, the temperature control measures such as optimizing the concrete mix ratio, reducing the temperature of the warehousing, inputting cool water and other temperature construction supervision system has been introduced which can ensure the whole construction process has good temperature during roller compacted concrete pouring, and the construction quality of RCC can meet the design requirements. The efficient and high-quality construction of the project has been promoted.
