冷却通水智能控制系统及其在锦屏一级拱坝中的应用

为提高大体积混凝土通水冷却的效率,实现精准控制与透明管理,防控混凝土裂缝,研制了冷却通水智能控制系统。经过3年实际工程现场试验与应用性研究,解决了该系统在水电工程大体积混凝土施工期复杂条件下稳定可靠运行的关键问题,并最终应用于世界最高双曲拱坝——锦屏一级拱坝工程中。结果表明,该系统实现了大体积混凝土施工期温度控制的标准化、精细化和智能化,极大地提高了大体积混凝土温控的效率。

Intelligent water-cooling control system and its application in Jinping-I Arm Dam

In order to improve water-cooling efficiency for massive concrete, to achieve precise control and transparent management, and to prevent and control concrete cracks, an intelligent water-cooling control system was developed. After three years of field trials of practical engineering and applicability research, key technology for stable and reliable operation under complex conditions in mass concrete construction of hydropower projects was created, and eventually the system was applied to the highest hyperbolic arch dam in the world, the Jinping-I Arm Dam. The results show that the system can realize standardization, refinement, and intelligentization of temperature control during the construction period of mass concrete, and greatly improve the efficiency of temperature control of mass concrete.
