Description

Technical Field

[0001] The present invention belongs to the technical field of concrete curing, and particularly relates to an integrated device and method for heat preservation and moisture preservation of prefabricated mass concrete. Background Art

[0002] As the cement hydration of the concrete mixture continuously proceeds, the internal temperature gradually rises. Since the concrete mixture is a non-uniform mixture composed of various materials, the different specific heat capacities of different materials cause the internal temperature distribution of the concrete to be very uneven. For a concrete structure, there is a temperature difference between both the inside and the surface and the external environment. The internal and external temperature difference ΔT inside and outside of the concrete itself and the surface air temperature difference ΔT between the concrete surface and the external environment. The existence of these two temperature differences causes the concrete to generate strain on the one hand, and on the other hand, the external constraints of the concrete structure and the constraints of each particle inside the concrete prevent, limit, and restrain the strain of the concrete, causing stress in the concrete. Mass concrete construction is often involved in modern buildings, such as the foundations of high-rise buildings, large equipment foundations, and hydraulic dams. Its main feature is its large volume, and the minimum dimension in any direction of the smallest cross-section is 1 m. Its surface coefficient is relatively small, the heat release of cement hydration is relatively concentrated, and the internal temperature rises relatively quickly. When the internal and external temperature difference of the concrete is large, temperature cracks will be generated in the concrete, affecting the structural safety and normal use.

[0003] The concrete cooling stage should be the heat preservation stage. Heat preservation can start from the highest temperature of the concrete or shortly after the temperature drops. Conventional heat preservation can add a layer of plastic cloth on top of straw bags and cotton felt, and the heat preservation effect is very good. If the heat preservation effect is still not ideal in this way, the thickness of another layer of heat preservation cotton quilt can be increased, and then a layer of plastic cloth can be covered on it. There are also some construction sites that first cover the film and then cover it with dry cotton quilts, straw bags or gunny bags and other heat preservation materials, and then cover a layer of plastic cloth on top, and the heat preservation effect is better, but it is not conducive to the heat dissipation in the cooling stage. It can be found that at present, the curing tools and methods for mass concrete are relatively simple and cannot better meet the requirements for the quality of conventional and special-shaped mass concrete.

[0004] To sum up, currently, there are the following problems with the heat preservation and moisture preservation means for mass concrete:

[0005] First, the heat preservation means are single and simple, and the whole process change of the heat hydration of mass concrete cannot be detected in real time;

[0006] Second, the moisture preservation means use artificial spraying, with low efficiency and serious waste of resources;

[0007] Third, it is difficult to cure special-shaped mass concrete;

[0008] Fourth, the surface change of mass concrete cannot be monitored in real time. Summary of the Invention
