实践证明,用冷水冷却粗骨料是一种简便有效的措施,而在诸多水冷骨料方法中,用直接向骨料输送皮带上喷淋冷水使骨料降温的方法具有占地面积小,运行环节少,操作简单和骨料温度回升小等优点.此方法已首次在葛洲坝水利工程施工中得到应用,并取得了令人满意的效果。本文的目的是想把为葛洲坝工程淋水冷却骨料所做的降温过程试验加以总结分析,以供参考。
Practice has proved that the use of cold water to cool the coarse aggregate is a simple and effective measure, and in many water-cooled aggregate method, with a direct conveyor belt to spray cold aggregate water to reduce the aggregate method has the advantages of small footprint, Fewer links, simple operation and small temperature rise of the aggregate, etc. This method has been applied for the first time in the construction of Gezhouba Water Conservancy Project and has achieved satisfactory results. The purpose of this paper is to summarize and analyze the cooling process test done for the water cooling aggregate of Gezhouba Project for reference.
