为确保三峡纵向围堰夏季混凝土浇筑质量 ,必须改善高温季节和高温时段砼浇筑仓面温度 ,为此开发了砼浇筑仓面降温系统———仓面喷雾降温机 在三峡二期工程I&IIB标段泄 9#坝段下块进行了单机降温试验 ,该机在不改变混凝土水灰比的情况下能有效地改善混凝土浇筑仓面温度 ,且不影响工人仓面操作 ,解决了三峡工程中仓面降温的难题 该机设计合理 ,性能优良 ,结构坚固耐用 ,可在高温环境施工的水利工程和建筑工程中推广使用
In order to ensure the quality of the concrete pouring in the longitudinal cofferdam of the Three Gorges Project in summer, it is necessary to improve the temperature of the concrete surface during the high-temperature season and the high-temperature period. For this purpose, a concrete cooling system for cooling the concrete surface has been developed --- the surface spray cooling machine Discharge of 9 # dam block under the single cooling test, the aircraft does not change the concrete water-cement ratio can effectively improve the temperature of concrete pouring warehouse surface, and does not affect the operation of warehouse workers to solve the Three Gorges Project warehouse surface The problem of cooling This machine is reasonable in design, excellent performance, durable structure can be used in high temperature construction of water conservancy projects and construction projects to promote the use of
