Description

Technical Field

[0001] The present invention relates to the field of mass concrete construction, and particularly to an adaptive hydration heat temperature control system and control method based on temperature measurement. Background Art

[0002] In recent years, with the large-scale development of infrastructure construction, the application of a large number of mass concrete structures has become popular. Structures such as various dams, large caissons, large pile caps, and main girders are all faced with the problem of heat dissipation of mass concrete hydration heat. Traditional structures often only measure the temperature distribution inside the concrete, and the cooling water passing method is single. When the temperature inside the concrete rises rapidly and generates a large amount of heat, there are often no effective control measures, which ultimately leads to many temperature cracks easily occurring inside or on the surface of the concrete. Along with the infiltration of external cooling water, it seriously affects the durability of the concrete. The cracking of mass concrete in many prestressed structures will also affect the efficiency of the prestressed system. Therefore, it is very important to control the mass concrete structure so that no hydration heat temperature cracks occur.

[0003] Traditional methods for heat dissipation of mass concrete hydration heat generally include embedding cooling water pipes in the concrete, and after the concrete solidifies and heats up, using the method of directly passing cooling water to cool the concrete structure; using ice-water mixture to stir the concrete to reduce the concrete pouring temperature; using retarders to delay the concrete setting time and delay the arrival time of the hydration heat peak.

[0004] However, the traditional cooling methods for controlling the structure temperature have the following disadvantages: First, the heat dissipation path of the bent connecting pipe is relatively long, and the cooling water gradually heats up during the heat dissipation process, resulting in a gradual decrease in the cooling efficiency; Second, the inlet temperature of the cooling water is not controlled. Considering extreme winter and summer working conditions, it may cause direct cracking at the cooling water inlet; Third, the heat accumulation state and the rising and falling temperature trend inside the concrete are not considered, and the heat dissipation is not controlled in zones according to the heat accumulation state and heat dissipation requirements of the mass concrete. It is difficult to control the uniformity of the internal heat distribution of the mass concrete only using a single specification of the heat dissipation scheme; Fourth, the cooling scheme does not consider the characteristics of the environment and seasonal climate, and it is difficult to control the temperature of the concrete surface and near the surface, and it is easy to generate large temperature stresses at local corner positions; Fifth, the temperature measurement points inside the mass concrete only provide the distribution characteristics of the structure's rising and falling temperature state and temperature field, and are not associated with the heat dissipation system for control. In most cases, only effective testing can be achieved while control is ineffective.

[0005] Therefore, how to effectively measure the temperature development and distribution of mass concrete hydration heat, effectively control the temperature field of mass concrete hydration heat, and effectively reduce and avoid the generation of temperature cracks has become an urgent problem to be solved by those skilled in the art. Summary of the Invention
