Description

Technical Field

[0001] The present invention relates to the technical field of tunnel water seepage monitoring, in particular to a tunnel water seepage monitoring device. Background Art

[0002] With the rapid development of infrastructure construction in my country, tunnel engineering has been widely used in transportation, water conservancy and other fields. Water leakage is a common and serious problem in tunnel operations. It not only affects the structural safety of the tunnel, but can also damage equipment and facilities within the tunnel, and even endanger driving safety.

[0003] Currently, monitoring tunnel seepage primarily relies on traditional methods and devices. For example, simple water collection containers are installed within the tunnel, and the amount of water inside is periodically measured to estimate seepage levels. This method suffers from low measurement accuracy, cannot reflect changes in seepage levels in real time, and is susceptible to interference from external factors, such as human and environmental factors, leading to inaccurate measurement results.

[0004] Some methods indirectly measure water seepage by installing water level sensors. However, these methods often only monitor water level fluctuations and fail to fully understand the quality of tunnel water seepage. Water quality is crucial for determining the source of tunnel water seepage, assessing the degree of corrosion in tunnel structures, and predicting tunnel lifespan. Failure to obtain timely and accurate water quality information can lead to misjudgments of tunnel defects, delaying tunnel maintenance and repair work.

[0005] In addition, tunnel seepage water may contain solid particles such as mud, sand, and debris. These particles are easily deposited in drainage pipes, causing pipe blockage, affecting drainage efficiency and the accuracy of monitoring data, which also needs to be solved urgently. Based on the above reasons, we proposed a tunnel water seepage monitoring device. Summary of the Invention

The telescopic rod 410 drives the water injection head 403 and the end head 404 to move in the monitoring tube 20 while extending and retracting. A water injection pump 402 is mounted on the top of the telescopic motor 401. A telescopic water pipe 409 is connected to the left side of the water injection pump 402. The telescopic water pipe 409 passes through the elbow 30 and extends into the monitoring pipe 20. A water inlet valve is mounted on the top of the water injection head 403.

A horizontal nozzle 407 is provided at the left end of the end head 404, which is interconnected. The horizontal nozzle 407 can be used to flush to the left, especially for flushing the turbine flowmeter 204. In addition, the water injection head 403 and the end head 404 can more comprehensively clean the monitoring tube 20 as the telescopic rod 410 moves. The first and second cleaning pipes 201 and 202 are used for cleaning and maintenance. The control valves in the first and second cleaning pipes 201 and 202 are opened to discharge the sewage more quickly, or the cleaned sewage is discharged further downward along the bend pipe 30. The top of the elbow 30 is provided with a accommodating chamber extending to the right, and the length of the accommodating chamber to the right can be adjusted as needed, so after cleaning, the water injection head 403 can be stored to the right to reduce obstruction to the flow channel of the elbow 30; A service valve 502 is installed in the middle of the connecting pipe 50, a sealing cover 503 is installed on the front side of the service valve 502, a pressure valve is installed in the service valve 502, and a display gauge of the pressure valve is set on the sealing cover 503; A self-generating flow detection device 501 is mounted on the upper portion of the connecting pipe 50.

Furthermore, the dimming bulb can be used independently of the power supply, and the pipeline flow status can still be displayed even when the monitoring device is powered off. The dimmer can control the bulb power by changing the voltage, current, or on-off time ratio, thereby adjusting the brightness. Multiple liquid level sensors are longitudinally arranged on the inner wall of the connecting pipe 50; an elbow 30 is also installed between the bottom of the connecting pipe 50 and the pumping pipe 60. A pumping pump 601 and a connecting pipe 602 are installed on the right side of the pumping pipe 60. The pumping pump 601 is responsible for pumping the water in the pipe to the right; The sewage cleaning device 70 includes a centrifuge 701, a connector 702, and a drive motor 703. The drive motor 703 is connected to the centrifuge 701 in a transmission manner. The centrifuge 701 is a horizontal screw centrifuge. The connector 702 is connected to the connecting pipe 602 to the left via a flange. Water is injected into the centrifuge 701 via a pumping pump 601, and then the drive motor 703 drives the centrifuge 701 to operate. A solids discharge pipe 705 extending downward is provided on the left side of the bottom of the centrifuge 701, and a liquids discharge pipe 706 extending downward is provided on the right side of the bottom of the centrifuge 701. After the sewage enters the drum, the high-speed rotation of the centrifuge 701 generates a strong centrifugal force field, which causes the denser solid phase to be thrown toward the drum wall and deposited there to form a sediment layer, which is then discharged through the solids discharge pipe 705. The less dense liquid phase forms a liquid ring layer inside the solid ring layer and is discharged through the liquid discharge pipe 706. When the water flow in the pipeline is small, a collection method is used for interval processing. For example, when the water flow is small, the feeding operation of the pumping pump 601 is first turned off, and the water flow is blocked and stored at the position between the pumping pump 601 and the connecting pipe 50. A plurality of liquid level sensors are provided in the connecting pipe 50. The thresholds of the liquid level sensors at different heights are set according to the capacity to issue an early warning. For example, when the water flow is stored close to the liquid level sensor below the circulation detection device 501, an early warning is issued, and the pumping pump 601 and the centrifuge 701 are started in sequence to pump the temporarily stored water into the centrifuge 701, and the centrifugal separation work is completed; An extension pipe is installed at the bottom of the liquid discharge pipe 706 for discharging the liquid; a sand conveying device 90 is installed at the bottom of the solid discharge pipe 705. The sand conveying device 90 includes a sewage pipe 901, a flushing pipe 902, a material leakage base 903, a conveyor belt 905, a lower hopper 906 and a vertical conveyor belt 908; The sewage pipe 901 is docked at the bottom of the solid discharge pipe 705. A leakage base 903 is installed at the bottom of the sewage pipe 901. A discharge port 904 is provided at the bottom of the leakage base 903. A lower hopper 906 is provided below the discharge port 904. A conveyor belt 905 is provided below the lower hopper 906. The solid waste discharged from the solid discharge pipe 705 falls into the leakage base 903 through the sewage pipe 901, and then the solid waste falls into the lower hopper 906 along the discharge port 904, and continues to fall downward onto the conveyor belt 905. A collection box 80 is placed on the left side of the conveyor belt 905. The solid waste finally falls into the collection box 80 along the conveyor belt 905. The size of the collection box 80 can be customized as needed. In this way, it is prevented that seepage water containing sediment is discharged at will, the position of the tunnel drainage pipe is blocked, and the time for regular inspection of the tunnel drainage system is extended. At the same time, an auxiliary conveyor belt 909 is provided at the position of the discharge port 904, and the auxiliary conveyor belt 909 conveys solid waste to the lower left lower hopper 906. A drop chute 907 is provided in the lower hopper 906, and the drop chute 907 is located at the lower left of the discharge port 904. A vertical conveyor belt 908 is provided in the drop chute 907, and the solid waste falls downward into the drop chute 907 and is conveyed downward by the vertical conveyor belt 908. The bottom diameter of the drop chute 907 gradually decreases to form an angle, which is used to effectively control the falling speed and flow of the sand material. A smaller angle can make the sand material fall relatively slowly and evenly. The angle can accurately guide the sand material to the conveyor belt, ensure the smooth flow of the sand material, prevent the sand material from deviating or scattering at the entrance, and ensure the stability and continuity of the sand conveying process. Furthermore, the vertical conveyor belt 908 and the chute 907 can prevent blockages. A reasonable angle design helps the sand material slide down smoothly. The continuous conveyance of the vertical conveyor belt 908 reduces the retention and accumulation of sand material in the chute 907, thus reducing the risk of blockage caused by sand material accumulation. This design also facilitates the removal of small debris that may appear, maintaining the normal operation of the sand conveying device 90. It can also cushion the impact of solid waste. When sand falls from above, the angle design can play a certain cushioning role, reducing the impact of sand on the conveyor belt 905, protecting equipment components and extending the service life of the equipment.

[0021] Working principle: Normally, the water quality in tunnels is relatively stable under normal conditions. However, water seepage can change the water quality in the pipe in a very short period of time. This is also the principle we monitor. Water seepage monitoring principle: A turbine flowmeter 204 is provided at the left end of the inner cavity of the monitoring tube 20. When water flows through the turbine flowmeter, the impact force of the water flow will drive the turbine to rotate. The speed of the turbine is proportional to the flow velocity of the water flow, and the flow velocity is related to the flow rate. By measuring and calculating the turbine speed, the flow rate of the water flow in the pipeline can be obtained, and thus the amount of water seepage in the tunnel can be known. In addition, the turbine stirring function of the turbine flowmeter 204 can fully mix and diffuse impurities, which helps to measure the flow rate more accurately and avoid the influence of uneven distribution of impurities on the measurement results; Multiple monitoring rings 207 are embedded transversely within the inner wall of the inner layer of the monitoring tube 20, each equipped with a water level sensor. These sensors detect the water level within the monitoring tube in real time. By comprehensively analyzing data from water level sensors at different locations, the user can understand water level fluctuations, determine whether there are any abnormal water level rises or falls, and thus reflect the dynamic changes in tunnel water seepage. pH Monitoring: The pH sensor on monitoring ring 207 detects the pH value of the water flow. The pH value is determined by measuring the hydrogen ion concentration in the water. Different geological conditions and sources of seepage can lead to different pH values ​​in the water. Therefore, pH monitoring can reveal the water quality characteristics of tunnel seepage and whether it is affected by the surrounding chemicals.

[0022] Conductivity Monitoring: Conductivity sensors measure the electrical conductivity of water. The higher the concentration of dissolved ions in water, the greater the conductivity. By monitoring conductivity, we can understand the content of dissolved salts, minerals, and other substances in the water, indirectly reflecting changes in water quality. This is important for determining whether seepage water is contaminated or contains unusual substances.

[0023] Dissolved oxygen monitoring: Dissolved oxygen sensors are used to detect dissolved oxygen levels in water. Dissolved oxygen levels are closely related to the water's self-purification capacity and microbial activity. By monitoring dissolved oxygen, we can assess the ecological status and health of water bodies, determine whether seepage water is in an aerobic or anoxic environment, and determine whether anaerobic microbial activity may be contributing to water quality deterioration.

[0024] Turbidity Monitoring: Turbidity sensors determine water turbidity by measuring the scattering or absorption of light by suspended particles in the water. The more suspended particles in the water, the higher the turbidity. Turbidity monitoring provides a direct indicator of impurity levels in the water, allowing users to understand the clarity of tunnel seepage water and the presence of potential solid particles. This provides valuable insights into the extent of erosion within the tunnel structure and the risk of drainage system blockage.

[0025] Temperature monitoring: Temperature sensors measure the temperature of flowing water. Temperature changes can reveal the source of seepage water and changes in environmental conditions. For example, groundwater temperatures may vary at different depths. Monitoring temperature can help determine whether seepage water originates from a specific stratum or is affected by ambient temperature.

[0026] The main control box 203 processes and analyzes the large amount of collected data. Using pre-set algorithms and models, it analyzes the relationships between various types of data, thereby drawing conclusions about tunnel water seepage, water quality, and water flow trends. For example, combining flow rate data and water level data can more accurately assess changes in tunnel water seepage; comparing water quality parameter data at different time points can determine whether water quality has changed or whether it is contaminated. In addition, a plurality of monitoring rings 207 are provided in the monitoring tube 20. The data of each monitoring ring (207) are mutually verified and compared with the data of other monitoring rings 207. By sampling at intervals, a variety of sampling data can be obtained. When analyzing, the average value, extreme value, and individual values ​​of each point can be taken for analogy and analysis, so as to obtain more accurate and real sampling data and help researchers conduct in-depth research on the subject of tunnel water seepage. At the same time, the provision of multiple monitoring rings 207 can also prevent individual damage from affecting the overall monitoring function, so that the monitoring device itself has a certain risk resistance capability. Based on the analysis results, the main control box 203 controls and coordinates the operation of the entire monitoring system. For example, if certain parameters are detected to be abnormal, the main control box 203 can issue instructions to activate corresponding devices or functions. For example, if the water seepage exceeds a preset threshold, the main control box 203 can control the pumping pump 601 to increase pumping force to ensure the normal operation of the drainage system. The main control box 203 also has a built-in timing circuit to trigger the pipe cleaning device 40 (which can also be instructed remotely to the main control box 203) to clean the inner wall of the monitoring pipe 20, ensuring the accuracy of the monitoring data and preventing the accumulation of sand and impurities that can block the pipe.

[0027] Data Storage and Transmission: The main control box 203 has a data storage function that can store collected historical data for subsequent review and analysis. Furthermore, the main control box 203 can transmit processed data to a remote monitoring center or other terminal device via wireless or wired communication, enabling personnel to understand tunnel water seepage and quality in real time, making timely decisions and implementing appropriate measures.
