Embodiment 2

[0045] This embodiment provides a method for automatically controlling the temperature reduction of circulating cooling water for large-volume concrete. The method is implemented based on the system for automatically controlling the cooling water for large-volume concrete circulating cooling water described in Example 1, and includes the following steps:

[0046] S1, the temperature measuring element 2 detects the temperature in the mass concrete, and feeds back the detected value to the temperature control switch 3;

[0047] S2, if the detected value is greater than the preset value of the temperature control switch 3, the temperature control switch 3 opens the solenoid valve 9, and controls the opening degree of the solenoid valve 9, and the cooling water flows into the sub-pipe.

[0048] Further, the following steps carried out after S2 are also included:

[0049] S3, after the temperature measuring element 2 detects that the temperature in the mass concrete drops below the...

Abstract

The invention discloses a mass concrete circulating cooling water automatic control cooling system and method, and belongs to the technical field of concrete cooling. The system comprises water collection boxes, cooling pipes, temperature measuring elements, a circulating mechanism connected with the water collection boxes and the cooling pipes and temperature switches connected with the temperature measuring elements and the circulating mechanism. The cooling pipes and the temperature measuring elements are pre-buried in mass concrete. The cooling pipes are pre-buried in the mass concrete ina layered manner, and each layer of cooling pipe is composed of multiple independent sub-pipes. Each sub-pipe is provided with the corresponding temperature measuring element. The temperature switchesare used for controlling the magnitude of the water conveying quantity generated after the circulating mechanism is shut down and started up according to the temperature, measured by the temperaturemeasuring elements, in the mass concrete. According to the system, zoning cooling can be carried out on the mass concrete, the temperature difference between various zones and the residual stress difference generated after hardening can be reduced, the risk that clearances appear in a concrete structure can be reduced, and the structural quality of the mass concrete structure can be improved.

Description

technical field [0001] The invention relates to the technical field of concrete cooling, in particular to a large-volume concrete circulating cooling water automatic control cooling system and method. Background technique [0002] According to my country's "Code for Mass Concrete Construction" GB50496-2009, it is stipulated that the minimum geometric size of the concrete structure entity is not less than 1m, or it is expected to be harmful due to temperature changes and shrinkage caused by the hydration of the cementitious material in the concrete. Concrete produced by cracks is called mass concrete. Modern buildings often involve large-volume concrete construction, such as high-rise building foundations, large-scale equipment foundations, water conservancy dams, etc. During the construction of mass concrete structures, the hydration reaction of cement will generate a large amount of heat of hydration. Considering the particularity of the concrete itself, an uneven temperatu...
