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.
