A kind of mass concrete temperature control method

Abstract

The present application relates to a temperature control method for mass concrete, including a temperature monitoring stage and a temperature adjustment stage; in the temperature monitoring stage, the temperature at different positions on the inner surface is monitored through a temperature monitoring system, and the temperature data is transmitted to a temperature monitoring center, which is monitored by monitoring personnel Temperature change and temperature difference; in the temperature adjustment stage, according to the temperature data monitored in the temperature monitoring stage, the temperature adjustment system is used to cool the location with higher temperature; the temperature adjustment system includes multiple sets of cooling water pipes set in the mass concrete, connected to The water inlet and return pipes at both ends of the water pipe, as well as the water source connected to the water inlet and the return pipe, the cooling water pipes are distributed in a serpentine shape from top to bottom in the mass concrete, and the cooling water pipes pass through cooling water to cool the position with higher temperature . The present application can reduce the difficulty of temperature control of mass concrete and improve the precision of temperature control.

Description

technical field [0001] The present application relates to the field of concrete construction quality control technology, and in particular, to a temperature control method for mass concrete. Background technique [0002] Mass concrete with a minimum geometric dimension of concrete structures of not less than 1 m, or concrete that is expected to cause harmful cracks due to temperature changes and shrinkage caused by hydration of cementitious materials in concrete, is called mass concrete. Large-scale concrete construction is often involved in modern buildings, such as high-rise building foundations, large-scale equipment foundations, and water conservancy dams. [0003] Mass concrete has the characteristics of large volume, relatively concentrated cement hydration heat release, small heat sink area, and relatively fast internal temperature rise. , which seriously affects the quality of the project. In order to prevent the phenomenon that the temperature difference between t...

Problems solved by technology

However, due to the limitation of its own principle, manual temperature control generally has the problems of time-consuming and labor-intensive control process and poor control accuracy.
