Cooling control method and circulating cooling system for mass concrete structure in water body
The invention provides a cooling control method and circulating cooling system for a mass concrete structure in a water body, and relates to the technical field of mass concrete construction. The cooling control method comprises the steps that when concrete is poured, a pre-embedded cooling water pipe is covered by the concrete, water in the water body and stored water in a cofferdam area are respectively and successively pumped as circulating cooling water for circulating water supply of the cooling water pipe; when it is monitored that the internal temperature of the concrete reaches a preset first temperature threshold value, the water in the water body is extracted again to serve as the circulating cooling water; meanwhile, the water flow velocity is regulated and controlled according to the temperature, obtained in real time, of each temperature measuring point till the concrete enters a stable period. According to the technical scheme, natural water resources around mass concrete construction of a water conservancy project are used for achieving allocation of the cooling water, the utilization rate of the water resources is increased, meanwhile, investment of water supply equipment is reduced, the quality and efficiency of engineering construction are ensured, and therefore the civilized construction requirements of energy conservation and environment protection are met.
本申请实施例提供一种水体中大体积混凝土结构的冷却控制方法及循环冷却系统，涉及大体积混凝土施工技术领域，该冷却控制方法通过在混凝土浇筑时，混凝土覆盖预埋设的冷却水管之后，分别先后抽取水体中的水和围堰区的蓄水作为循环冷却水对所述冷却水管进行循环通水；当监测到混凝土内部温度到达预设的第一温度阈值时，再次抽取所述水体中的水作为循环冷却水；同时，根据实时获取的各温度测点处的温度调控水流速，直至混凝土进入稳定期。本发明技术方案利用水利工程大体积混凝土施工周围的天然水资源实现冷却水的调配，提高水资源的利用率，同时降低了供水设备投入，确保工程施工的质量和效率，从而达到节能环保的文明施工要求。
