Large-area field concrete usually requires sufficient thickness and load-bearing capacity to support heavy machinery and large traffic flow. Due to the large area, it is crucial to ensure the uniformity and consistency of concrete. Any uneven curing or maintenance may cause cracks and defects. Considering the use environment and conditions of large-area field concrete, there are extremely high requirements for durability, including frost resistance and crack resistance. Reasonable design of concrete mix ratio, control of concrete temperature and humidity, timely cutting of expansion joints, etc. are all effective ways to reduce the occurrence of future cracks. The maintenance methods of large-area field concrete include but are not limited to covering method, spraying curing agent method, water curing method, steam curing method and wet cloth covering method. In actual use, different maintenance methods need to be implemented according to different applicable situations. Good maintenance can not only prevent premature cracking, but also improve the durability and bearing capacity of concrete.

Problems that arise during the subsequent maintenance process are difficult to solve in a timely manner, affecting the maintenance effect. The maintenance work is not carried out in accordance with the maintenance plan, and its scientificity and effectiveness need to be improved. Summary of the invention

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1 A method for maintaining large-area concrete floor comprises the following steps:

[0041] S101, the multi-dimensional acquisition module divides the site into C areas according to the construction batches and forms a construction data set, and then uses environmental sensors to monitor the environment of the C areas respectively, and forms all environmental monitoring results into an environmental data set. The multi-dimensional acquisition module connects to the central control console through the network to collect the appearance data set;

[0042] The construction data set includes the construction data of concrete in all areas of the field. The expression of the construction data set is: t represents the time point when the construction of the area is completed. The time point when the concrete of the area is completed directly affects the number of subsequent curing days. The concrete built in the early stage relies more on natural curing, such as traditional methods such as sprinkling water and covering for moisturizing, while the concrete built in the late stage relies on spraying curing agents and using water-saving and moisturizing curing films. s represents the construction materials, construction methods and construction conditions used in the construction batches to which the area belongs. to The maintenance of large-area concrete is a systematic process, which corresponds to the construction time, construction materials, construction methods and construction conditions of different construction batches. It is necessary to comprehensively consider the data and conditions of the construction time, construction materials, construction methods, construction conditions, temperature control and other aspects. For example, the curing time of concrete using ordinary Portland cement should not be less than 7 days. The curing time of concrete with retarder, impermeable concrete, high-strength grade concrete, etc. should be appropriately extended to not less than 14 days.

[0043] The environmental data set includes the environmental temperature and humidity data of concrete in all areas of the field. The expression of the environmental data set is: w represents the ambient temperature of the concrete in the area, s represents the ambient humidity of the concrete in the area, to The ambient temperature and humidity of concrete in each area correspond to each other. The ambient temperature and humidity have a decisive influence on the state of concrete. Under high temperature conditions, the evaporation of water in concrete is accelerated, resulting in incomplete hydration reaction, which reduces its compressive strength. Under high humidity conditions, the initial and final setting time of concrete is prolonged, and the early strength development is slow. At the same time, excessive moisture may also lead to a decrease in the bonding force between aggregate and paste, affecting the overall performance of concrete.

[0044] The appearance data set includes the appearance data of concrete in all areas of the field. The expression of the appearance data set is: l represents the historical appearance data of the regional concrete, d represents the current appearance data of the regional concrete, to Corresponding to the historical appearance data and current appearance data of concrete in each area in turn;

[0045] S102, the state assessment module analyzes the difference in concrete compressive strength at two adjacent time points in the same area based on the construction data set, and calculates and generates a strength difference Qdcy accordingly. The calculation process is as follows:

[0046] According to the construction data set, the construction data of concrete in all regions are sorted from early to late in chronological order, denoted as S t ,in, t represents the time when the construction of the area is completed, q represents the number of the area to which it belongs, to The construction data of concrete corresponding to the earliest completed construction batch to the latest completed construction batch;

[0047]

[0048] In the formula, Qdcy represents the strength difference, Qd represents the compressive strength value of the regional concrete, N represents the maximum force that the regional concrete can withstand pressure, that is, the failure load, and M represents the bearing area of ​​the regional concrete under pressure. Indicates that the construction data S of concrete in all areas are calculated in chronological order from early to late t The compressive strength value of concrete from the earliest construction batch to the latest construction batch, Qd t-1 Indicates the compressive strength of concrete at the previous time point, Qd t Indicates the compressive strength of concrete at the current time point, Qd t-1 -Qd t It represents the difference in concrete compressive strength between two adjacent time points. Indicates the construction data S of concrete in all areas t , calculate the difference in concrete compressive strength at two adjacent time points in the same area, which is the strength difference. According to the strength difference Qdcy, the difference in concrete compressive strength directly reflects the quality of the project, which facilitates the subsequent strict control of concrete curing conditions and effectively improves its durability and service life;

[0049] S103, the state assessment module analyzes the difference between the ambient temperature and humidity of concrete in different areas and the average ambient temperature and humidity according to the environmental data set, and calculates and generates the environmental difference Hjcy accordingly. The calculation process is as follows:

[0050]

[0051] In the formula, Hjcy represents the environmental difference, Indicates the average ambient temperature and humidity. represents the sum of the ambient temperature and humidity of all concrete areas in the environmental data set, C represents the total number of concrete areas divided in the field, and W max represents the maximum temperature value of concrete in a single area in the environmental data set, W min represents the lowest temperature value of concrete in a single area in the environmental data set, W max -W min It represents the difference between the highest and lowest temperatures of concrete in a single area. It means that according to the numbering sequence of regions 1 to C in the environmental data set, the difference between the highest temperature and the lowest temperature of concrete in each region is calculated in turn. represents the ambient temperature and humidity of concrete in the i-th area in the environmental data, where i = {1, 2, 3, ..., C}, represents the difference between the ambient temperature and humidity of the concrete in the ith area and the average ambient temperature and humidity, The standard deviation of the dispersion degree of the ambient temperature and humidity of concrete in all regions in the environmental data set and the average ambient temperature and humidity is the environmental difference. According to the environmental difference Hjcy, the fluctuation of ambient temperature and humidity in each region can be understood, which is convenient for quick judgment on whether to use cooling or moisturizing measures to prevent concrete cracking, sanding and color difference.

[0052] S104, the state assessment module analyzes the difference in the appearance of concrete at two adjacent time points in the same area based on the appearance data set, and calculates and generates a maintenance index Yhzs accordingly. The calculation process is as follows:

[0053] According to the appearance data set, the total number of cracks, sanding and color difference in the concrete appearance of a single area is counted and recorded as XC, where XC = {XC1, XC2, XC3, ..., XCC}, where XC1 to XCC correspond to the number of times the concrete in regions 1 to C has cracks, sand, and color differences;

[0054] Yhzs=∫1 C (XC sj-1 -XC sj )

[0055] In the formula, Yhzs represents the maintenance index, XC Sj-1 Indicates the number of times that the concrete in a single area has cracks, sand, and color difference at the previous time point. t Indicates the number of times that the concrete in a single area has cracks, sand, and color difference at the current time point. sj-1 -XC sj It indicates the difference in the number of times the concrete surface has cracks, sanding and color difference at two adjacent time points. It means that according to the appearance data set, the difference in the number of times the concrete appearance has cracks, sand and color difference at two adjacent time points in the same area is calculated, which is the maintenance index. According to the maintenance index Yhzs, the change trend of the concrete appearance in the area can be quickly judged, and whether the concrete continues to crack, sand and color difference can be judged. The systematic management has high judgment accuracy;

[0056] S105, the maintenance management module determines the state trend of the concrete according to the strength difference Qdcy, the environmental difference Hjcy and the maintenance index Yhzs. The maintenance management module compares the strength difference Qdcy with the preset strength difference. If the compressive strength difference of a single area in the strength difference Qdcy is greater than the preset strength difference, the maintenance management module determines that the concrete state of the area lacks maintenance, generates a compressive maintenance report and transmits it to the central control console. Specifically, the variability of the compressive strength of the concrete can be effectively reduced by covering the concrete surface with a water-saving and moisturizing maintenance film. The maintenance management module compares the environmental difference Hjcy with the preset environmental difference. If When the environmental difference Hjcy is greater than the preset environmental difference, the maintenance management module determines that the concrete state lacks maintenance, generates an environmental maintenance report and transmits it to the central control console. Specifically, cooling or moisturizing measures can be used to slow down and even out the hydration reaction of the concrete, reduce shrinkage cracks, and improve the overall quality and uniformity of the concrete. If the maintenance index Yhzs is negative, the maintenance management module determines that the concrete cracking, sanding and color difference are serious, and generates an emergency maintenance report and transmits it to the central control console. Emergency repair of these cracks is not only related to the aesthetics of the structure, but also directly affects the safety and durability of the building. Scientific maintenance is more stable.
