对大体积混凝土温度控制采用风冷却技术的可行性进行探讨,通过试验模拟,研究了不同管材、管径大小、是否加湿等工况下对风冷却技术降温效果的影响,并与不同流速下通水降温效果进行对比研究。试验结果表明:选用1.1mm壁厚、70mm直径、6063型铝合金管作为冷却风管,在加湿状态下,采用11m/s的风速对大体积混凝土进行温度控制优于30L/min通水降温的降温效果,证实大体积混凝土采用风冷却在技术上是有效可行的。
The feasibility of applying air cooling technology to temperature control of mass concrete is discussed. The effects of different cooling technologies such as pipe diameter, pipe diameter and humidification on the cooling effect of air cooling technology are studied through experiments and simulations. Water cooling effect of comparative study. The test results show that the temperature of 11m / s wind speed is better than that of 30L / min water cooling when the wind speed of 11m / s is selected as the cooling air duct with 1.1mm wall thickness, 70mm diameter and 6063 aluminum alloy tube. Cooling effect, confirmed that mass concrete using air cooling is technically feasible.
