用钢筋支架兼做冷凝水管对厚大体积混凝土进行降温的施工技术

Made From Steel Stents and Condensed Water Pipe Cooling of Large Volume Concrete Construction Technology

大体积混凝土施工具有水化热高、收缩量大、容易开裂等特点,所以,大体积混凝土施工重点主要是将温度应力产生的不利影响减少到最小,防止和降低裂缝的产生和发展。论文通过用钢筋支架兼做冷凝水管对厚大体积混凝土进行降温的方法,使大体积混凝土施工时利用循环水来降低混凝土内部的温度。

Mass concrete construction with high hydration heat, shrinkage, easy cracking and other characteristics, therefore, the main emphasis of mass concrete construction is to minimize the adverse effects of temperature stress, prevent and reduce the emergence and development of the crack. This paper made from steel stents and condensate pipes of large volume concrete cooling method, the mass concrete construction by using circulating water to reduce the temperature inside the concrete.
