Description

Technical Field

[0001] This invention patent belongs to the field of geotechnical engineering technology, specifically relating to an intelligent electroosmosis maintenance system for the entire life cycle of soft soil foundations. Background Technology

[0002] Soft soil is widely distributed in coastal and inland areas of my country. Its high compressibility, low strength, and high water content pose serious challenges to various engineering projects. Before construction, foundation treatment is necessary to improve the bearing capacity and stability of soft soil foundations. After the project is put into use, the foundation still needs to withstand the long-term effects of environmental factors (such as heavy rainfall and groundwater level fluctuations), which may lead to secondary settlement, strength degradation, and other problems, threatening the safety of the project. Currently, electroosmosis, as a soft soil foundation reinforcement technology, still faces the following key issues in practical applications:

[0003] The electroosmosis process relies on continuous high voltage, resulting in low energy utilization. Furthermore, the soil resistivity increases during dehydration, leading to a significant decrease in efficiency in the later stages. Design parameters largely depend on empirical presets, resulting in uneven reinforcement effects. Existing technologies focus only on short-term reinforcement, lacking the ability to dynamically control the foundation's condition during operation (such as moisture content and pore water pressure), making it unable to effectively cope with changes in environmental loads and exhibiting poor long-term stability. High energy consumption leads to a surge in electricity costs, and the high cost of electrode materials, coupled with the difficulty in recycling electrodes, contradicts the principles of green construction. Existing electroosmosis systems are only used for reinforcement during the construction phase and are not integrated with subsequent maintenance systems, making it impossible to reuse existing circuit systems for long-term monitoring and control. The lack of real-time data feedback and adaptive control mechanisms results in delayed maintenance response, potentially leading to engineering accidents due to disasters (such as softening induced by heavy rain), thereby endangering life and property.

[0004] Existing electroosmosis technology suffers from insufficient efficiency, poor economics, and a lack of full-cycle management, severely limiting its engineering applicability. By implementing intelligent and low-carbon transformations, a comprehensive electroosmosis reinforcement-maintenance system covering the entire lifecycle of a project can be constructed, significantly improving the long-term stability of soft soil foundations while reducing operation and maintenance costs and safety risks, providing a new paradigm for the development of green and low-carbon foundation treatment technologies. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent electroosmosis maintenance system for the entire life cycle of soft soil foundations, in order to solve the problems of insufficient efficiency, poor economy and lack of full-cycle management in existing electroosmosis technologies, and to achieve full-cycle coverage of reinforcement during the construction period and dynamic monitoring and maintenance during the operation period of soft soil foundations, thereby improving long-term stability and safety.

[0035] Preferably, each system achieves intelligent collaboration through the "monitoring-feedback-control" logic: the sensors of the field control system transmit the measured data to the intelligent monitoring and control system via optical fiber.

The power supply system adjusts the power supply status of the cathode and anode accordingly, and the sprinkler system starts humidification as needed, forming a closed-loop control for the active prevention and control of foundation diseases.

[0036] The beneficial effects of this invention are as follows:

[0037] 1. This invention is based on an intelligent control strategy for the electroosmotic soft soil reinforcement process, which can dynamically manage the anode boundary through real-time monitoring data.

[0038] By implementing spray control to the anode electrode tube according to optimized frequency and water volume parameters, this technical measure has dual engineering benefits:

[0039] (1) Interface resistance regulation effect: Spraying can reduce the resistivity of the anode-soil contact interface by 29.10% as measured by actual tests, which can significantly improve the power conversion efficiency and reduce system energy consumption. The mechanism is that the formation of the water film improves the ion migration environment at the electrode-soil interface.

[0040] (2) Long-term maintenance of electroosmotic efficiency: The intelligent sprinkler system can extend the effective working radius of the anode through water replenishment, realizing continuous driving of far-field soil drainage, breaking through the effective reinforcement range limitation of traditional electroosmotic methods, maintaining a stable electrochemical oxidation environment, promoting the formation of soil cementing materials, and avoiding efficiency decay caused by excessive anode acidification through pH control. This control method has been experimentally verified to extend the duration of electroosmotic drainage efficiency by 63.3%, while reducing the moisture content of the reinforced soil by 11.84% and increasing the shear strength by 134.89%.

[0041] 2. The intelligent monitoring and control system of this invention collects key parameters of foundation engineering, such as mechanics, hydrology, and deformation, in real time through a multi-source sensor network, and relies on artificial intelligence algorithms for multi-dimensional data fusion analysis and risk warning. When the system detects potential hazards such as abnormal moisture content or excessive displacement, it can autonomously trigger the on-site control system and the sprinkler humidification system to implement boundary control and electro-osmotic drainage intervention measures in the target area, realizing proactive prevention and control of foundation diseases. This demonstrates the advantages of closed-loop control of monitoring-feedback-control. Key control parameters need to be dynamically optimized based on real-time monitoring data such as soil conductivity, drainage rate, and interface potential difference.

[0042] 3. The intelligent monitoring and control system of the present invention can be activated periodically or on demand through intelligent decision-making based on real-time monitoring data or preset conditions. It can dynamically improve the physical and mechanical properties of the foundation soil by utilizing the electroosmotic effect of the field control system, thereby enhancing its durability and long-term stability. In addition, when the foundation is suddenly damaged due to natural disasters, the intelligent monitoring and control system, the field control system, the power supply system, and the sprinkler humidification system can also respond quickly through the Internet of Things and combine the prediction and optimization capabilities of artificial intelligence to quickly restore the bearing capacity of the foundation as an emergency measure.

[0043] 4. The intelligent electroosmosis maintenance system, which integrates intelligent monitoring and control system, field control system, power supply system and spray humidification system, can significantly improve the efficiency of electroosmosis reinforcement system, enhance environmental adaptability and achieve long-term stable operation, providing solid technical support for the long-term safe and stable operation of soft soil foundations in electroosmosis reinforcement projects.

Detailed Implementation

[0050] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0051] like Figure 1 As shown, the present invention includes a power supply system 100, an intelligent monitoring and control system 200, a field control system 300, and a spray humidification system 400.

[0052] The power supply system 100 is connected to the cathode 302, anode 303, nozzle 308 and universal head 309 in the field control system 300 via wires 304. The wires 304 pass through the intelligent power switch 120 for controlling automatic opening and closing.

[0053] The intelligent monitoring and control system 200 is connected to the four-in-one sensor 305, electronic humidity meter 307, pore water pressure gauge 311 and surface displacement monitor 312 respectively via optical cable 204. The intelligent monitoring and control system 200 is also connected to the intelligent power switch 120, solenoid valve 403 and flow meter 404 via PLC controller 203.

[0054] The field control system 300 is connected to the solenoid valve 403 in the spray humidification system 400 via a hose 402;

[0055] The field control system 300 feeds back measured data to the intelligent monitoring and control system 200 through sensors. The intelligent monitoring and control system 200 then transmits the feedback signal to the power supply system 100, the field control system 300, and the spray humidification system 400 to perform corresponding actions, thereby achieving proactive prevention and control of foundation diseases.

[0056] Example 1

[0057] (1) Investigate the geological and hydrological conditions of the soft soil foundation, clarify the physical and mechanical properties of the soft soil through geotechnical tests, and then determine the spacing and depth of the tubular electrodes.

[0058] (2) After the tubular electrode is driven into the soft soil, it is connected to the intelligent power switch 120, solar panel 102 or wind turbine 103 through wire 304.

[0059] (3) A four-in-one sensor 305, a pore water pressure gauge 311 and a surface displacement monitor 312 are buried near and in the middle of several anodes 303 and cathodes 302 in several representative areas. An electronic humidity meter 307 is placed and fixed inside the tube of anode 303. All the above sensors are connected to the computer through optical fiber and 204RS-485 hub.

[0060] (4) The site is divided into zones according to the site topography and the future construction of buildings. A spray nozzle 308 is placed and fixed at the pipe opening of all anode pipes in each zone. Each nozzle is connected to a multi-way quick connector through a hose 402 and connected to the solenoid valve 403 of the spray humidification system 400.

[0061] (5) Based on the monitoring data of the intelligent monitoring and control system 200 and relying on the artificial intelligence algorithm, when the difference in the moisture content of each section reaches 5%, turn on the intelligent power switch 120 to power the electrode and start the spray humidification system 400 at the anode 303 to spray into the anode tube. The spraying method is: spray once every 24 minutes for the first 28 hours and once every 12 minutes for the next 32 hours. The amount of water sprayed once is 0.2 mL. When the difference in the moisture content of each section drops to 2%, stop the spray humidification system 400.

[0062] (6) Stop electroosmotic reinforcement when the monitoring data is stable;

[0063] (7) The intelligent monitoring and control system will continuously collect on-site monitoring data. When the system detects hidden danger indicators such as abnormal moisture content or excessive displacement, it can automatically trigger the on-site control system and the spray humidification system to implement electroosmotic drainage intervention measures for the target area by controlling the anode boundary, so as to achieve proactive prevention and control of foundation diseases.

[0064] Comparative Example 1

[0065] Everything else is the same as in Example 1, except that:

[0066] The anode was not sprayed.

[0067] Figures 2-5 These are the experimental results of the anode boundary spray treatment group and the no-spray control group set in Example 1. The experiment was conducted in an indoor model, and all experimental parameters were kept consistent except for the anode boundary spray condition.

[0068] Figure 2 The anodic interface resistance in the anode boundary spray treatment test was higher than that in the non-spray control group for the first 30 hours, but the anodic interface resistance of the non-spray control group increased significantly after 30 hours. The average anodic interface resistance of the non-spray control group was 212.48 Ω, while that of the spray treatment test was 150.66 Ω, representing a 29.10% reduction after spraying. The mechanism is that the formation of the water film improves the ion migration environment at the electrode-soil interface, which can significantly improve the energy conversion efficiency and reduce system energy consumption.

[0069] Figure 3In the control group without spraying, the drainage rate was less than 3 mL / h at 30 h, while in the spray-treated experiment, the net drainage rate (after deducting the injection volume) was less than 3 mL / h at 49 h. This demonstrates that spray treatment can effectively extend the electroosmotic drainage time by 63.3%.

[0070] Figure 4 The figure shows the soil moisture content distribution after the experiment. As can be seen from the figure, from the anode to the cathode (except for the cathode point), the moisture content of the spray treatment experiment was lower than that of the non-spray control group. The average moisture content of the non-spray control group was 26.47%, while the average moisture content of the spray treatment experiment was 23.33%, a decrease of 11.84% compared to the control group.

[0071] Figure 5 The figure shows the distribution of soil shear strength after the test. As can be seen from the figure, from the anode to the cathode (except for the cathode point), the shear strength of the sprayed treatment test is higher than that of the non-sprayed control group. The average shear strength of the non-sprayed control group is 39.44 kPa, while the average shear strength of the sprayed treatment test is 92.64 kPa, which is 134.89% higher than that of the control group.

[0072] Detailed implementation methods and principles:

[0073] Soft soil reinforcement stage: Several electrodes, including anodes 303 and cathodes 302, are driven into the soft soil foundation at certain intervals. These electrodes are connected to the positive and negative terminals of solar panels 102, wind turbines 103, or other forms of clean energy power generation devices, respectively, and the power supply is determined by a smart power switch 120. A four-in-one sensor 305 (capable of simultaneously monitoring soil moisture content, temperature, conductivity, and pH), a pore water pressure gauge 311, and a surface displacement monitor 312 are embedded in the soil between the anodes 303 and cathodes 302. The system integrates the four-in-one sensor, pore water pressure gauge, and surface displacement monitor. Each sensor is hardwired to the data acquisition module via shielded cables. The real-time multi-dimensional monitoring data is conditioned by an RS-485 hub 201 and transmitted to the central processing computer 202 via a bus, forming a complete distributed monitoring data stream.

[0074] A spray nozzle 308 is placed inside the anode tube, and it is connected in sequence to a universal joint 309, a hose 402, and a solenoid valve 403. Based on the Modbus communication protocol, when the computer acquires monitoring data through the real-time data acquisition system, it processes and analyzes the data through a programmed intelligent algorithm. For example, when the electronic hygrometer 307 detects that the humidity inside the anode tube has reached a preset threshold, the spray humidification system 400 will automatically start or stop according to the program instructions, thereby ensuring that the humidity inside the anode tube 303 is always maintained within the preset range.

[0075] When the four-in-one sensor 305 detects that the soil moisture content at a certain interface has reached the set value or that the moisture content difference between interfaces is large, the system will automatically trigger the intelligent power switch 120 and the solenoid valve 403 through the PLC controller 203. The solenoid valve will further activate the flow meter 404, transformer 405, speed controller 406, and power pump 407. Water in the water storage tank 401 will be sprayed into the anode 303 pipe through the hose 402 and the above-mentioned equipment according to the optimized frequency and water volume parameters set by the computer program. By adjusting the boundary conditions of the anode 303, the effectiveness of the electro-osmosis reinforcement system will be further adjusted until the foundation bearing capacity requirements are met.

[0076] Maintenance Phase: After the foundation treatment is completed and the building 310 is put into use, the intelligent monitoring and control system 200 collects key parameters of the foundation engineering, such as mechanics, hydrology, and deformation, in real time through a multi-source sensor network, and performs multi-dimensional data fusion analysis and risk warning based on artificial intelligence algorithms. When the system detects hidden danger indicators such as abnormal soil moisture content or excessive displacement, it can autonomously trigger the field control system 300 and the sprinkler humidification system 400 to implement electroosmotic drainage intervention measures for the target area by controlling the boundary of the anode 303, thereby achieving proactive prevention and control of foundation diseases. The intelligent monitoring and control system 200 can be activated periodically or on demand through intelligent decision-making based on real-time monitoring data or preset conditions, and dynamically improve the physical and mechanical properties of the foundation soil by utilizing the electroosmotic effect of the field control system 300, thereby enhancing its durability and long-term stability. In addition, in the event of sudden foundation damage caused by natural disasters, the intelligent monitoring and control system 200, the field control system 300, the power supply system 100, and the sprinkler humidification system 400 can also respond quickly through the Internet of Things, combined with the prediction and optimization capabilities of artificial intelligence, as an emergency measure to quickly restore the bearing capacity of the foundation.

[0077] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative and not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
