Description

Technical Field

[0001] This invention relates to the field of concrete curing technology, and in particular to an automatic spray concrete curing system with a heat-free flexible pipeline. Background Technology

[0002] With the continuous development of construction technology, concrete curing, as a crucial link in ensuring project quality, is increasingly demanding in terms of automation and efficiency. In modern construction engineering, the combination of automatic spraying and watering has been widely applied to concrete curing to effectively avoid drying shrinkage cracks caused by water shortage during hydration reactions, while improving the automation and adaptability of curing.

[0003] Existing spraying and watering devices typically rely on fixed piping systems, a design that presents significant limitations for curing large-area or complex concrete walls. Firstly, the installation of fixed piping systems is challenging, especially in complex and structurally variable construction environments, where laying and adjusting pipelines often consumes considerable time and manpower. Secondly, the maintenance costs of fixed piping systems are high, and repair or replacement is difficult once pipelines are damaged, impacting overall construction efficiency. Furthermore, existing systems rely on real-time monitoring of wall strength values ​​for switching between spraying and watering; however, limitations in sensor accuracy or data transmission delays can lead to untimely control, affecting curing effectiveness and potentially causing concrete surface quality problems.

[0004] Therefore, developing a concrete curing system that can overcome the aforementioned shortcomings is of great significance. In particular, addressing the problems of poor pipeline flexibility, high maintenance costs, and untimely control in existing technologies, an innovative technical solution is needed to achieve efficient, flexible, and reliable concrete curing, meeting the demands of modern construction for automation and high-quality curing. Summary of the Invention

[0005] This invention relates to the field of concrete curing technology, specifically to an automatic spray concrete curing system using a flexible pipeline without heat fusion. The background section mentions that existing technologies suffer from problems such as reliance on fixed pipeline systems for spraying and watering devices, lack of flexibility, and untimely control due to sensor inaccuracy or data delays, making it difficult to meet the needs of efficient and flexible curing in complex construction environments.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic spray concrete curing system with a heat-free flexible pipeline, comprising the following steps: S1: First, construct the flexible pipeline module and electrically connect it to the spray control unit; S2: The relative humidity of the concrete surface is collected in real time through the humidity monitoring module in the spray control unit; S3: The temperature analysis module in the spray control unit is used to predict the trend of concrete surface temperature change; S4: The water pressure parameters in the flexible pipeline are dynamically adjusted through the pressure regulation module in the spray control unit; S5: The spray coverage area is accurately assessed through the flow calculation module in the spray control unit; S6: Establish a dynamic control matrix for the parameters collected from S2 to S5, and input the performance of each parameter into the unified matrix P=[H,T,P,F]T; S7: Obtain the expression for the comprehensive performance of spray maintenance, Pd; S8: Based on the Pd expression of comprehensive performance of spray maintenance, design a highly adaptable and low-energy intelligent spray logic; S9: Flexible pipeline and interface protection structure designed with high-strength corrosion-resistant materials.

[0007] In S1, the flexible pipeline module includes a humidity monitoring module, a temperature analysis module, a pressure regulation module, and a flow calculation module. Both the humidity monitoring and temperature analysis modules are electrically connected to the flexible pipeline, and both are electrically connected to the pressure regulation module. The pressure regulation module is electrically connected to the external interface and records and stores the data. The humidity monitoring module collects and analyzes the relative humidity of the concrete surface in real time to ensure that the spray volume matches actual needs. The temperature analysis module obtains the trend of concrete surface temperature changes and predicts the optimal spraying time based on the ambient temperature. The pressure regulation module dynamically adjusts the spray intensity based on changes in water pressure within the flexible pipeline to adapt to different construction scenarios. The flow calculation module calculates the spray coverage area to optimize water resource utilization and avoid over-spraying.

[0008] In S2, relative humidity is calculated by establishing a relationship between the humidity of the concrete surface and the ambient humidity, predicting the equilibrium humidity of the concrete surface under specific working conditions, and deriving an equilibrium humidity expression. Since there is a one-to-one correspondence between the equilibrium humidity and the water content of the concrete surface, the relative humidity value of the concrete surface is obtained by looking up a table based on the obtained equilibrium humidity. Considering the case of uneven humidity distribution on a large area of ​​concrete surface, this design uses the lowest relative humidity value as the overall surface humidity assessment value.

[0009] In S3, the temperature change trend prediction is achieved by obtaining two time intervals [T(i), T(i+1)] of the concrete surface temperature, calculating the temperature difference ΔT(i) within these intervals, and then predicting the concrete surface temperature change trend Tt within this time period. This trend is then compared with the reference temperature Tb, thus using the temperature fluctuation as an important basis for spray control.

[0010] In S4, the water pressure parameter uses the pressure change within the flexible pipeline as the criterion for judging the spray intensity, and the specific calculation method is as follows. Meanwhile, in the spray control system, considering the possibility of uneven spraying due to excessively high water pressure, lower pressure values ​​are used as a reference.

[0011] In S5, the flow coverage area is calculated using dynamic flow statistics, taking into account the changes in water flow during the spraying process in the flexible pipeline. The calculation method for the flow coverage area is as follows: In the statistics, the maximum coverage area Fmax is used as a reference value.

[0012] In S6, to determine the overall performance of spray maintenance, the influence of each parameter on the system under different conditions is classified into levels, obtaining normalized indices for each parameter. For a specific parameter, the classification rule for its level pi(x) is as follows. Since a good performance for a particular spray maintenance parameter does not necessarily mean an ideal overall effect, but an abnormal parameter directly affects the overall effect, based on this principle and the level of each parameter, the weighting coefficient βi of a specific parameter in the overall performance of spray maintenance is defined as follows. To express the overall performance as a percentage, the percentage conversion of each spray maintenance parameter is performed as follows.

[0013] In S7, the specific expression for the overall performance Pd of spray maintenance is: Where pi(x) represents the normalized value of the i-th parameter, βi represents the weighting coefficient of the i-th parameter, and n is the total number of parameters. The expression of the comprehensive performance Pd can intuitively describe the overall situation of spray maintenance. On the other hand, the ratio of dynamic weights also effectively shows the degree of influence of each parameter on the overall situation during use.

[0014] In the S9, the flexible pipeline and interface protection structure uses high-strength corrosion-resistant materials to wrap the combined structure of the flexible pipeline and spray control unit, and then forms an isolation structure through sealed packaging, with a pressure relief valve installed on the outside of the sealed packaging.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By developing heat-free flexible pipeline technology, a highly adaptable spray curing system is built, solving the problems of difficult layout and high maintenance cost of traditional fixed pipeline systems, and providing new technical means for concrete curing in complex construction environments.

[0016] 2. By studying the trends of humidity and temperature changes on concrete surfaces and their response characteristics to the external environment, a performance evaluation model for spray curing is established to solve the problem of the inability to quickly predict the curing effect of concrete.

[0017] 3. Based on the performance evaluation model of spray curing and the requirements of construction scenarios, design intelligent spray control logic for complex construction environments to solve the problem of insufficient flexibility of spray curing systems.

[0018] 4. Based on the material and structural characteristics of flexible pipelines, design a safe, isolated, and highly stable pipeline protection structure to solve problems such as aging and corrosion that may occur during long-term use of flexible pipelines. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the overall system structure of the present invention; Figure 2 This is a flowchart of the spray control unit's workflow; Figure 3 Cross-sectional view of flexible pipeline and interface protection structure; Detailed Implementation

[0020] This invention provides a heat-free flexible pipeline automatic spray concrete curing system. Its core lies in achieving efficient and flexible concrete curing through the coordinated operation of the flexible pipeline module and the spray control unit. The following is a detailed description of the technical solution of this invention in conjunction with the accompanying drawings and specific embodiments.

[0021] Firstly, according to Figure 1 The schematic diagram of the overall system structure shows that the flexible pipeline module and the spray control unit are electrically connected to form a complete spray curing system. The flexible pipeline module includes a humidity monitoring module, a temperature analysis module, a pressure regulation module, and a flow calculation module. These modules are responsible for collecting humidity and temperature change trends on the concrete surface, regulating water pressure parameters within the flexible pipeline, and evaluating the spray coverage area, respectively. The spray control unit acts as the data processing center, receiving data from each module, performing comprehensive analysis, and generating a dynamic control matrix P=[H,T,P,F]T. This matrix integrates parameters such as humidity H, temperature T, pressure P, and flow rate F for subsequent calculation of the overall spray curing performance Pd.

[0022] In actual operation, the first step is to construct a flexible pipeline module and connect it to the spray control unit. The flexible pipeline is made of high-strength, corrosion-resistant material. This material was chosen because it can effectively resist environmental erosion during long-term use, ensuring the system's stability and durability. Figure 3As shown, the flexible pipeline and interface protection structure is designed with a multi-layer wrapping form. The innermost layer is the flexible pipeline itself, the outermost layer is wrapped with a high-strength corrosion-resistant material, and then a sealed package is used to form an isolation structure. A pressure relief valve is installed on the outside of the sealed package to release excess pressure when the internal pressure of the pipeline is too high, thereby protecting the safety of the pipeline and interface. This design not only improves the service life of the flexible pipeline, but also solves the problems of difficult layout and high maintenance costs of traditional fixed pipeline systems, and is especially suitable for concrete curing needs in complex construction environments.

[0023] Next, the system enters the data acquisition phase. The humidity monitoring module collects relative humidity data of the concrete surface in real time through sensors installed on the flexible pipeline. Specifically, the humidity monitoring module predicts the equilibrium humidity of the concrete surface under specific working conditions by establishing a relationship between the humidity of the concrete surface and the ambient humidity, and obtains the relative humidity value by looking up a table. Considering the uneven distribution of humidity on a large area of ​​concrete surface, this design selects the lowest relative humidity value as the overall surface humidity assessment value. For example, in a certain construction scenario, the humidity monitoring module detected that the humidity distribution range of the concrete surface was 60% to 80%, and the system ultimately used 60% as the reference value for subsequent calculations. The temperature analysis module further predicts the trend of concrete surface temperature Tt within two time intervals [T(i), T(i+1)] by obtaining the temperature difference ΔT(i) of the concrete surface temperature within two time intervals [T(i), T(i+1)]. Assuming that the temperature difference ΔT(i) recorded by the temperature analysis module is -2℃ in a certain time interval, and the reference temperature Tb is 25℃, the system will determine whether to start the spraying operation based on the comparison between the temperature difference and the reference temperature. This prediction method based on temperature change trends can effectively avoid the problem of inappropriate spraying timing caused by fluctuations in ambient temperature.

[0024] After collecting humidity and temperature data, the system enters the pressure regulation and flow calculation phase. The pressure regulation module dynamically adjusts the water pressure parameters within the flexible pipeline to ensure the spray intensity adapts to different construction scenarios. Specifically, changes in water pressure within the flexible pipeline are used as a criterion for judging spray intensity. For example, when the water pressure is low, the system automatically increases the pump's power to raise the pressure; conversely, when the water pressure is too high, it reduces the pump's power or opens the pressure relief valve to prevent uneven spraying. Furthermore, the flow calculation module accurately assesses the spray coverage area through dynamic flow statistics. Assuming the maximum coverage area Fmax recorded during a spraying operation is 50 square meters, the system uses this as a reference value to optimize water resource utilization efficiency and avoid resource waste caused by over-spraying.

[0025] After completing the above data acquisition and control, the system enters the stage of constructing the dynamic control matrix. For example... Figure 2The diagram shows the workflow of the spray control unit. The spray control unit inputs various parameters collected by the humidity monitoring module, temperature analysis module, pressure regulation module, and flow calculation module into a unified matrix P=[H,T,P,F]T. Based on this, the system normalizes each parameter into a standardized index pi(x) and defines a weighting coefficient βi according to the degree of influence of each parameter on the overall spray effect. For example, the weighting coefficient for humidity might be set to 0.4, for temperature to 0.3, for pressure to 0.2, and for flow rate to 0.1. These weighting coefficients are set based on experimental data and the needs of actual application scenarios, ensuring that the system can flexibly adjust the spray strategy under different operating conditions. Finally, the overall spray maintenance performance Pd is calculated using the following formula: Where pi(x) represents the normalized value of the i-th parameter, βi represents the weighting coefficient of the i-th parameter, and n is the total number of parameters. For example, in a practical application case, the normalized value of humidity is 0.8, the normalized value of temperature is 0.7, the normalized value of pressure is 0.6, and the normalized value of flow rate is 0.9, with corresponding weighting coefficients of 0.4, 0.3, 0.2, and 0.1, respectively. Then, the comprehensive performance Pd of spray maintenance is calculated as follows: Pd=0.4×0.8+0.3×0.7+0.2×0.6+0.1×0.9=0.74Pd=0.4×0.8+0.3×0.7+0.2×0.6+0.1×0.9=0.74 Therefore, the calculation results of the comprehensive performance Pd of spray maintenance can intuitively reflect the overall situation of the current spray maintenance, and the ratio of dynamic weights can also clearly show the degree of influence of each parameter on the overall effect during use.

[0026] Based on the overall performance (Pd) of spray curing, the system is further designed with highly adaptable and low-energy-consumption intelligent spraying logic. For example, when the Pd value is below a set threshold (e.g., 0.6), the system automatically adjusts the spray intensity, frequency, or coverage area to improve the curing effect; while when the Pd value is above the threshold, the spray intensity is appropriately reduced to conserve water resources. This intelligent spraying control logic not only meets the flexibility requirements of complex construction environments but also effectively reduces energy consumption and improves the system's economy.

[0027] Finally, regarding the design of the flexible pipeline and interface protection structure, this invention employs high-strength, corrosion-resistant materials for wrapping and forms an isolation structure through sealed packaging. This design has demonstrated excellent performance in practical applications. For example, in a site test, the flexible pipeline showed no significant aging or corrosion after three months of continuous use, and the pressure relief valve outside the sealed packaging successfully released excess pressure caused by excessive water pressure on multiple occasions, ensuring the safety and stability of the system.

[0028] In summary, this invention achieves efficient and flexible concrete curing through the collaborative operation of a flexible pipeline module and a spray control unit, combined with multiple technologies such as humidity monitoring, temperature analysis, pressure regulation, and flow calculation. Compared to existing technologies, this invention not only solves the problems of difficult layout and high maintenance costs associated with traditional fixed pipeline systems, but also significantly improves the effectiveness and flexibility of concrete curing by establishing a spray curing performance evaluation model and designing intelligent spray logic. Furthermore, the design of the flexible pipeline and interface protection structure further enhances the system's stability and durability, providing a novel technical solution for concrete curing in complex construction environments.
