Layered water-stopping system and methods for hydrogeological exploration under complex hydrogeological conditions Technical Field
[0001] This invention relates to the field of hydrogeological exploration technology, specifically to a layered water-stopping system and method for hydrogeological exploration under complex hydrogeological conditions. Background Technology
[0002] Hydrogeological exploration refers to the hydrogeological investigation and research conducted to ascertain the hydrogeological conditions of a region. Its aim is to understand the formation, distribution, and movement patterns of groundwater and surface water. This provides a basis for the rational exploitation and utilization of water resources and for the correct design and construction of foundation and piling projects. It includes both underground and above-ground hydrogeological exploration. Groundwater exploration mainly investigates the changes in groundwater level, flow direction, and chemical composition at different times of the year, ascertains the burial conditions and corrosiveness of groundwater, determines the potential changes and impacts of groundwater during the construction and use of buildings, and proposes prevention and control recommendations. In the process of groundwater exploration, layered water-stopping operations are required first. Traditional layered water-stopping operations involve first inserting clay balls into the annular gaps in the well casing and compacting them to isolate the groundwater inside and outside the well casing before conducting pumping tests. However, using clay balls for isolation is an overly cumbersome and time-consuming operation with extremely low overall efficiency.
[0003] Current water-stopping devices used in hydrogeological exploration often have the following shortcomings under complex hydrogeological conditions:
[0004] 1. It cannot effectively adapt to various geological conditions, especially complex hydrogeological environments;
[0005] 2. The water-stopping effect is unstable, and there is a risk of seepage and leakage, which leads to the mixing of groundwater in different layers during hydrogeological exploration, and the measured hydrogeological parameters of this layer are not representative.
[0006] 3. The equipment is complex to install, increasing workload and costs;
[0007] 4. The water-stopping strategies for multi-layered aquifers are not clearly defined, resulting in poor effectiveness;
[0008] 5. The materials used in water-stopping equipment are prone to aging and have poor durability. Summary of the Invention
[0009] The purpose of this invention is to provide a layered water-stopping system and method for hydrogeological exploration under complex hydrogeological conditions, which maintains a stable water-stopping effect under complex geological conditions, simplifies the equipment installation process and extends the service life of the equipment; significantly improves the work efficiency of hydrogeological exploration, reduces exploration costs, and improves the accuracy of exploration, providing a more reliable basis for subsequent engineering decisions.
[0010] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:
[0011] Layered water-stopping systems for hydrogeological exploration under complex hydrogeological conditions include:
[0012] Layered water-stop pipe structure: This layered water-stop pipe is made of high-strength plastic or stainless steel, possessing good mechanical strength and corrosion resistance. The length of each pipe section can be adjusted according to specific survey requirements, typically ranging from several meters to over ten meters. The sections are connected by expandable joints with a sealed structure to ensure effective water-stopping at the joints.
[0013] Layered waterstop membrane: Each section of the pipe is equipped with a layered waterstop membrane, which can be made of materials such as elastic rubber. The waterstop membrane should have the following characteristics: good elasticity and flexibility to ensure a tight bond with the stratum; good resistance to high and low temperatures to adapt to different environmental conditions; and excellent resistance to chemical corrosion to cope with various chemicals in groundwater.
[0014] Sensor Module: The sensor module consists of miniature moisture sensors and pressure sensors, installed on each segment of the stop membrane. The moisture sensor determines whether water sealing is necessary by detecting the presence of water molecules. The pressure sensor monitors the water pressure in each layer in real time to provide reference data. These sensors should be highly sensitive and have a rapid response.
[0015] Automatic Control Unit: Located in the ground control room, the automatic control unit communicates and exchanges data with the sensor modules. Its functions include receiving data from the sensor modules, analyzing and processing the data, and instructing the corresponding waterproof membrane to expand or contract based on real-time conditions. The automatic control unit also has data storage and transmission capabilities, allowing it to transmit operating status and data to the user's mobile device for real-time monitoring and remote control.
[0016] Quick-installation mechanism: Each segment of the waterstop pipe is equipped with a quick-locking structure at its end, allowing workers to quickly connect and disconnect segments by rotating or pushing / pulling. This mechanism should have reliable sealing performance to ensure effective waterstopping at the joints. Furthermore, the connectors should be designed to withstand a certain amount of external pressure to prevent displacement or damage to the segments during operation.
[0017] Repair and Reinforcement Module: The pipe body is equipped with a repair membrane and colloidal material to repair leaks and enhance water-stopping effects. The repair membrane can be made of a self-soluble material that automatically releases repair material to seal even minor leaks.

[0019] Furthermore, the sensor module specifically includes:
[0020] Choosing Miniature Moisture and Pressure Sensors: When selecting sensors, it's necessary to consider their suitability for groundwater environments, such as high humidity and high temperature. Miniature moisture sensors can use capacitive or resistive sensors to detect the presence of water molecules. Pressure sensors can be selected based on their high pressure range and accuracy.
[0021] Sensor module installation: The sensor module should be installed on the stope membrane of each segment. The sensor should be positioned as close as possible to the groundwater source to ensure accurate moisture and pressure data are obtained.
[0022] Configure sensor parameter thresholds: Sensor parameter thresholds can be set according to geological conditions and exploration needs. For example, a threshold for a moisture sensor can be set to detect the presence of groundwater or determine whether water-stopping measures are needed. Thresholds for a pressure sensor can be used to determine the pressure status of groundwater.
[0023] Data Acquisition and Processing: The sensor module communicates and exchanges data with the automatic control unit, transmitting moisture and pressure data to the ground control room.

[0024] Real-time monitoring and remote control: The automatic control unit can transmit operating status and data to the user's mobile device, enabling real-time monitoring and remote control. Users can view sensor data, equipment status, and adjust parameters via their mobile devices, thereby achieving real-time monitoring and remote control of hydrogeological conditions.
[0025] The specific settings for parameter thresholds should be determined based on specific geological conditions, engineering requirements, and equipment performance, and optimized through field investigation and testing. The threshold for moisture sensors can be set according to the range of groundwater level variations in the investigation area, while the threshold for pressure sensors can be set according to groundwater pressure variations. Specific values should be determined based on experiments and practical applications to ensure accuracy and reliability.

[0054] Installation of the repair membrane: The repair membrane is installed inside the waterstop pipe body, which can be achieved by wrapping or puncturing. The repair membrane should be tightly fitted to the waterstop pipe body to ensure effective sealing of the leakage points.
[0055] Automatic release of the repair membrane: The repair membrane should contain a self-dissolving repair material. When a minor leak is detected, the membrane will automatically release the repair material to seal it. Automatic release of the repair membrane can be triggered by changes in internal pressure or by sensor detection.
[0056] Selection of Reinforcing Colloid: Choose a reinforcing colloid material with high adhesion and sealing performance. The reinforcing colloid can enhance the water-stopping effect through manual injection. The reinforcing colloid should have good flowability and adhesion so that it can quickly flow through the pipe and fill the leakage points.
[0057] Reinforcing colloid injection: When a large leak is detected or a stronger sealing effect is required, workers can inject reinforcing colloid material into the sealing pipe. The injection location and quantity should be determined according to specific needs to ensure effective sealing of the leak.
[0058] The release threshold of the repair membrane can be set based on the size of the leak point, water pressure, and leakage rate; the injection threshold of the reinforcing colloid can be set based on the size of the leak point and surrounding geological conditions. Specific values should be determined based on experiments and practical applications to ensure the accuracy and reliability of the repair and reinforcement effects. Simultaneously, the timing and effectiveness of repair and reinforcement should be considered to balance repair effectiveness and work efficiency.

Next, the control_stop_membrane() method is called to control the expansion or contraction of the water shut-off membrane. Finally, the update_data_to_user_device() method is called to transmit the operating status and data updates to the user's mobile device.
[0158] Appropriate modifications and adjustments are needed based on the actual situation. For example, the judgment logic in the `analyze_sensor_data()` method needs to be adjusted according to the actual sensor data format and threshold settings. Furthermore, the specific functions of membrane expansion, contraction, and maintaining a normal state need to be implemented according to the actual control mechanism and device interface.

[0160] The specific implementation of the sensor module program includes:
[0161]
[0162]
[0163] In the main program, an instance of SensorModule is created, and the read_moisture_sensor() and read_pressure_sensor() methods are called on each segment of the stop membrane to read data from the moisture sensor and pressure sensor. Then, the get_sensor_data() method is called to obtain the sensor data, and the data is passed to the automatic control unit for analysis and control.
[0164] Implement the specific functionalities of the `read_moisture_sensor()` and `read_pressure_sensor()` methods based on the actual sensor interface and data reading method. Furthermore, adjust the format and structure of the data returned by the `get_sensor_data()` method according to the actual sensor data format.
