大藤峡水利枢纽船闸混凝土冷却供水系统施工设计

Design of water supply system for concrete cooling in shiplock construction of Datengxia Hydraulic Project

大藤峡工程处于亚热带,船闸工程结构复杂、混凝土施工强度高,温控难度较大且冷却供水系统布置场地有限。基于以上条件,研究设计了一套切实可行的冷却供水系统,达到削减船闸混凝土浇筑块初期水化热温升,控制混凝土块体最高温度的目的。

Datengxia Hydraulic Project is located in the subtropical zone.Great challenges have been encountered during shiplock building due to the complicated engineering structures,high intensity of concrete construction,difficulties with temperature control and limited space for layout for cooling system.Studies have been carried out in accordance with the above conditions and a desirable water supply cooling system is developed,in order to reduce heat of hydration in the early phase of concrete pouring and realize target of controlling highest temperature of the concrete blocks.
