Description

Technical Field

[0001] The present invention relates to the technical field of concrete curing, and in particular to an intelligent curing system and a curing method for a concrete structure. Background Art

[0002] Concrete curing is to artificially create set humidity and temperature conditions to allow the newly poured concrete to harden and increase in strength normally or at an accelerated rate. Conventional concrete curing methods include the following:

[0003] 1. Natural curing: divided into watering curing and spraying plastic film curing. The former is to cover the concrete with straw mats and keep it moist by sprinkling water frequently. The latter is to spray the perchlorethylene resin plastic solution on the concrete surface with a spray gun. After the solution evaporates, a thin film is formed on the concrete surface, isolating the concrete from the air, preventing the evaporation of water in the concrete and ensuring the normal hydration of cement. After the curing is completed, the film will age and fall off by itself;

[0004] 2. Steam curing: Place the concrete components in a curing room filled with saturated steam or a mixture of steam and air to accelerate the hardening of the concrete in a high temperature and humidity environment. The requirement for concrete curing humidity is that the relative humidity is above 95%.

[0005] At present, the main maintenance method used on construction sites is watering maintenance in natural maintenance. Since watering maintenance is artificial water spraying, it is difficult to ensure that every area can be evenly watered, and it is also difficult to monitor maintenance, which may lead to insufficient maintenance in some areas, affecting the strength and durability of concrete; and the maintenance process requires a lot of manpower and material resources for frequent watering maintenance, and the construction cost is high; if too much water is sprayed, the surface of the concrete will have more moisture, causing the cement paste of the concrete mixture to be too thin locally, which is prone to penetration, thereby affecting the density of the concrete and reducing the strength of the concrete; this process often lacks an effective management mechanism, resulting in a large amount of water resources being wasted.

[0006] Therefore, how to design a set of equipment with simple structure, easy operation and improved maintenance efficiency, while reducing the labor output cost and water resources required for this process, has a strong practical significance. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide an intelligent maintenance system and method for concrete structures. The intelligent maintenance equipment of the present invention can automatically spray according to the humidity conditions on the surface of the concrete structure, eliminating the need for manual spraying. Not only is the maintenance cost low, but the spraying effect can also be guaranteed, effectively reducing the labor cost and water resources required for the maintenance of the concrete structure, and has great promotion value.

[0030] α=0.24653e (Ω / 21.92181) +0.24653e (Ω / 26.79332) -0.26541;
