摘要
在高温季节进行坝体二期水管冷却时,受到外界气温的影响,在表面5~7m范围内,很难降低到规定的温度,接缝不能充分张开,影响到接缝灌浆质量.针对这个问题进行分析,提出了简便的计算方法,应用此方法进行水管冷却计算,根据所得结果表明,采取相应厚度的保温板进行表面保温。
When pipe cooling is conducted in hot seasons, the temperature of concrete near the surface will not drop. In this case, the superficial thermal insulation is needed. A computation method is proposed in this paper and an example is given to show the effect of superficial thermal insulation.
