Problems solved by technology

[0004] Although the existing intelligent temperature control method for mass concrete has been applied in engineering and has achieved certain application effects, it only automatically adjusts the inflow control by controlling the opening of the valve, and then realizes the cooling process of mass concrete. Full temperature control is not achieved

Abstract

The invention relates to the field of building and civil engineering, and discloses mass concrete temperature control equipment and a temperature control method. The mass concrete temperature control equipment and the temperature control method aim to solve the problem that related arts are not excellent in effect. The mass concrete temperature control equipment comprises a water tank, a control device, a plurality of branch water pipes, a plurality of first temperature sensors and a plurality of second temperature sensors; the branch water pipes, the first temperature sensors and the second temperature sensors are located in concrete; the water tank has a plurality of water storage spaces which are separated from one another for accommodating fluids at different temperatures; first regulating valves connected to the control device are arranged at inlets of the plurality of branch water pipes; the first regulating valves, the first temperature sensors and the second temperature sensors are connected to the control device; the quantity of the first temperature sensors is greater than that of the branch water pipes and the quantity of the second temperature sensors is greater than that of the branch water pipes; and the first temperature sensors are arranged in the corresponding branch water pipes and the second temperature sensors are arranged around the outer walls of the branch water pipes in concrete.

Description

technical field [0001] The invention relates to the fields of architecture and civil engineering, in particular to a large-volume concrete temperature control device and a temperature control method. Background technique [0002] The meaning of mass concrete generally refers to the cast-in-place concrete whose volume is so large that measures must be taken to deal with the temperature difference caused by the heat of hydration, reasonably solve the stress caused by the temperature difference deformation, and control the generation of cracks or limit the development of cracks. [0003] Since the high-rise foundations are mostly box-shaped, raft-shaped, and pile-capped foundations with large concrete volumes, this structure has the characteristics of thick structure, large shape, dense steel reinforcement, large amount of concrete, complex engineering conditions, and high construction technology requirements. . The possibility of cracks caused by external loads is very small....
