陕西南郑县云河水库碾压混凝土坝温度监测与聚乙烯冷却水管通水降温效果分析

Analysis on RCC dam temperature monitoring and polyethylene cooling water pipeline water feeding cooling effect in Yunhe Reservoir of Nanzheng County in Shaanxi Province

本文分析了云河水库碾压混凝土坝施工的温控形势,探讨了在仓面碾压混凝土施工中埋设聚乙烯冷却管的必要性。通过坝内安装的测温计定时监测混凝土温度数值,为坝体温度控制提供依据。结合冷却水温度测量,使聚乙烯冷却管通水降温作用通过有效控制得到更好发挥,对类似工程具有一定的参考价值和借鉴意义。

In the paper,temperature control trend of RCC dam construction in Yunhe Reservoir is analyzed. The necessity of embedding polyethylene cooling pipelines in warehouse surface RCC construction is discussed. The thermometer installed in the dam can be adopted for monitoring concrete temperature value on time. Basis is provided for dam temperature control. Cooling water temperature measurement is combined to better exert The water feeding cooling effect of polyethylene cooling pipeline through effective control. It has certain reference value and significance for similar projects.
