摘要
新建湖南株洲攸县地方铁路工程,混凝土数量大,桥梁占正线全长的26.4%。本文叙述埋设冷却管方法、混凝土养护期内测温监控、养护管理降低大体积混凝土内外温差的作用,保证混凝土施工质量。
The new project of Hunan Zhuzhou Youxian local railway concrete bridge, uses large quantity, and the bridge ac-counting for 26.4%of the length of line. This paper describes the embedding cooling tube method, concrete curing period measured temperature monitoring, maintenance and manage-ment to reduce the temperature difference between inside and outside of large volume concrete, ensure the quality of concr-ete construction.
