摘要
结合南水北调中线总干渠青兰渡槽工程，采取降低出机口混凝土拌合物温度、减少混凝土运输浇筑过程中温度回升、控制混凝土水化热温升等技术措施，实现了高温季节混凝土施工温度控制标准；并通过掺加纤维素和改善养护方法，减少混凝土裂缝；使用快易收口网模板，保证大体积混凝土施工能够快速连续浇筑作业。为类似工程施工提供参考。
According to the main canal of the middle route of the South-to-North Water Diversion Project to reduce Qing lan aqueduct, outlet temperature of concrete mixture, reducing the concrete pouring process, control the temperature rise of concrete hydration heat temperature rise and other technical measures, to realize the temperature control standard of concrete construction in hot season; and adding the maintenance method of cellulose and improve, reduce the concrete crack; the use of quick closing network template, ensure the construction of large volume concrete to rapid and continuous casting operation. Provide a reference for similar engineering construction.
