Problems solved by technology

Therefore, in order to meet the large amount of cooling water required for the cooling process of large-volume concrete, it is necessary to configure a cooling water deployment plan, such as a cooling water reuse device consisting of a refrigeration system, a circulating water tank, a cold water delivery system, and a return water collection tank. This not only requires a certain construction cost, but also the pressure on the refrigeration unit is very high, which consumes a lot of energy and fails to meet the civilized construction requirements of energy saving and environmental protection

Embodiment 2

[0061] See Figure 4 , Figure 4 It is a schematic flow chart of the cooling control method of the mass concrete structure in the water body provided by the second embodiment. The cooling control method takes the central controller as the execution subject and includes the following steps:

[0062] Step S11, when concrete is poured, after the concrete covers the pre-embedded cooling water pipes, the water in the water body and the water stored in the cofferdam area are successively extracted as circulating cooling water to circulate the cooling water pipes, and according to the real-time obtained The temperature at each temperature measuring point regulates the water flow rate, so that the temperature difference between the inlet and outlet water of the cooling water pipe is within the preset temperature difference range.

[0063] During concrete implementation, the temperature of concrete entering the mold should be controlled during the concrete pouring construction process...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of large-volume concrete construction, in particular to a cooling control method and a circulating cooling system for a large-volume concrete structure in a water body. Background technique [0002] The rapid economic development has led to the acceleration of infrastructure construction. Water conservancy projects are closely related to people's lives. Therefore, quality control is very critical in the construction process. The main material of water conservancy projects is reinforced concrete. Due to the complexity of water conservancy project conditions and higher and higher construction technology requirements, mass concrete structures have been used in key parts of the project. The quality control of mass concrete construction technology directly affects the realization of water conservancy building functions. [0003] During the pouring process of mass concrete, due to the large temperature difference ...
