The mass concrete structure is liable to cause concrete cracking due to large internal temperature variation during construction. In order to reduce or prevent cracking, a method of burying a cooling water pipe inside concrete is generally used to control the temperature inside concrete. Circulating water with the temperature lower than that of the concrete is required to be introduced into the cooling water pipe in the concrete temperature rise stage to improve the temperature reduction efficiency of the concrete; in the concrete cooling stage, the concrete cooling rate is generally required to be not more than 2 ℃/day, if the cooling rate exceeds the value, the concrete can crack, and at the moment, in order to slow down the temperature reduction speed in the concrete, circulating water with the temperature higher than that of the concrete needs to be introduced into the cooling water pipe to slow down the concrete cooling speed. This minimizes cracking of the concrete due to temperature changes. At present, in actual engineering, the temperature of circulating water is reduced only by manually adding ice into a water tank in the temperature rise process of concrete, but the temperature reduction amplitude of the circulating water is not easy to control due to the large volume of the water tank, and real-time dynamic adjustment along with the temperature change of the concrete cannot be performed.
