水利枢纽工程大体积混凝土低温季节施工探讨

Discussion on Construction of Mass Concrete in Low-temperatureSeason for Water Conservancy Project

在水利枢纽工程中,对混凝土材料的数量及质量需求较高,但由于水利施工工期跨度大,在低温季节往往也需进行大体积混凝土的施工,然而考虑到混凝土施工对于温度的敏感性,混凝土在低温季节施工将面临较多质量隐患,因而要重视低温环境下混凝土施工要点,保障水利工程建设质量。首先就水利工程混凝土施工特点予以分析,探讨了低温环境下混凝土施工难点及存在问题,并提出了低温季节混凝土施工相关要求,以作参考。

In the water conservancy project,the quantity and quality of concrete materials are relatively high.However,due to the large span of water conservancy construction,large volume concrete construction is often required in the low temperature season.However,considering the sensitivity of concrete construction to the low temperature season,concrete will face more hidden quality problems,so it is necessary to pay attention to the key points of concrete construction in low temperature environment to ensure the quality of water conservancy projects.This article first analyzes the characteristics of concrete construction in water conservancy projects,discusses the difficulties and problems of concrete construction in low temperature environment,and puts forward the relevant requirements of low temperature season concrete construction for reference.
