[0005] Based on the above situation, at present, there is no suitable method for concrete curing, how to scientifically and effectively carry out "moisture curing" and real-time control in the process according to the natural environment conditions (temperature, humidity, wind speed) and concrete related parameters, and the quality of concrete cannot be obtained. Guarantee, it is difficult to ensure the effective realization of the goal of concrete moisture conservation

Embodiment Construction
[0038] The specific implementation of the real-time control method for the moisturizing and curing process of the exposed surface of natural environment concrete involved in the present invention will be described in detail below in conjunction with the accompanying drawings.
[0039]
[0040] The following are the basic information of the second-line ship lock in Qingyuan, Guangdong Province involved in the first and second embodiments:
[0041] Qingyuan No. 2 Ship Lock is a class III navigable structure, with the largest designed ship class: 1000t, and the size of the ship lock: 220×34×4.5(m). The upper and lower sluice heads and the sluice chamber adopt an integral structure.
[0042] Such as Figure 4 As shown, the upper sluice head adopts a reinforced concrete monolithic structure, the plane outline size is 50×65m (length×width), the opening width is 34.2m, and the effective net width after deducting the steel handguard is 34m. The length of the bottom plate is 50m, a...

Abstract
The invention provides a real-time control method for the moisturizing and maintenance process of the exposed surface of concrete in a natural environment, which is characterized in that it comprises the following steps: Step 1. Real-time collection of ambient air temperature, ambient air humidity, and ambient wind speed; Step 2. Determine the spraying time T k ; Step 3. Calculate the time to stop spraying according to the relevant parameters of the concrete and the collected ambient air temperature, ambient air humidity and ambient wind speed. Step 4. Cycle maintenance: according to the spraying time T k Spray the concrete and follow the stop spraying time T b Stop spraying and continue to circulate until it reaches the maintenance age. The invention not only considers the influence of ambient humidity, ambient wind speed and ambient temperature on concrete, but also further considers the influence of the size of the concrete curing surface, and the exchange of humidity on the concrete surface caused by laminar flow and turbulent flow under the conditions of different wind speeds and different sizes of concrete curing surface. Therefore, the calculation accuracy is higher, the result is more accurate, and the maintenance effect is better.
Description
technical field [0001] The invention belongs to the field of engineering structure concrete maintenance, and in particular relates to a real-time control method for the moisturizing and maintenance process of the exposed surface of natural environment concrete. Background technique [0002] Concrete curing means that after concrete is poured, it gradually solidifies and hardens due to cement hydration, and hydration requires appropriate temperature and humidity conditions. Therefore, in order to ensure that the concrete has suitable hardening conditions and its strength continues to increase, it is maintained. From the principle of humidity exchange, curing must ensure that there is sufficient humidity inside the concrete, and there is basically no humidity exchange between the concrete on the curing surface and the air, that is, the curing must maintain the humidity of the concrete, hereinafter referred to as moisturizing curing. [0003] Such as figure 1 As shown, the con...
