Embodiment Construction
[0022] The present invention will be further described below in conjunction with specific embodiment:
[0023] like figure 1 As shown, a circulating water natural cooling system for controlling cracks in large-volume concrete of the present invention includes a natural cooling tank 1, an isolation plate 2, a circulating water pipe 3, a cooling pool 4, and large-volume concrete 5.
[0024] The isolation plate 2 is arranged inside the natural cooling tank 1 , the large-volume concrete 5 is arranged inside the cooling pool 4 , and the natural cooling tank 1 and the large-volume concrete 5 are connected into one body through the circulating water pipe 3 .
[0025] By adding the isolation plate 2 inside the natural cooling tank 1, the internal water source can be recycled, and then the natural cooling tank 1 and the large-volume concrete 5 are connected together through the circulating water pipe 3 to form a circulating water cooling system with a natural cooling tank.

Abstract
The invention discloses a circulating water natural cooling system and method for controlling mass concrete cracks and belongs to the technical field of constructional engineering. The circulating water natural cooling system for controlling mass concrete cracks is suitable for control over the temperature cracks in the surface of mass concrete. By reasonably arranging sub-regions of a natural cooling tank, an internal water source can be repeatedly used; afterwards, circulating water is stored on the surface of the mass concrete, so that the redundant heat on the surface of the concrete is brought outwards through heat exchange by circulating water in time; in this way, the temperature difference of the concrete between inside and outside is reduced, the probability that the temperature cracks in the surface of mass concrete occur is greatly lowered, the engineering cost can be lowered by 50%, the construction period can be shortened by 30%, and low carbon and environmental friendliness are really achieved.
Description
technical field [0001] The invention relates to a circulating water natural cooling system and a method for controlling cracks in large-volume concrete, belonging to the technical field of construction engineering. Background technique [0002] The rapid development of modern science and technology has promoted the great progress of my country's engineering construction. Modern engineering structures are developing in a comprehensive direction with higher and higher volumes, more complex shapes, and more diverse functions. Mass concrete structures Then came into being. However, during the pouring and curing process of concrete, a large amount of hydration heat will be generated, and the temperature stress generated by the hydration heat will cause structural cracks. This kind of crack has strong destructive power to the structure and seriously affects the use of the structure. How to minimize or avoid the occurrence of temperature cracks is a practical engineering problem th...
