Description

Technical Field

[0001] This invention relates to the field of dam safety monitoring technology, and in particular to a method and device for repairing and automatically monitoring dam deformation and settlement pipes. Background Technology

[0002] Dam safety monitoring, as a core component of water conservancy infrastructure operation and maintenance, is widely used in dam structural health assessment and disaster early warning. Among related technologies, a vertical displacement monitoring system for dams has been constructed through the collaborative operation of steel settlement pipes and inclinometers. Specifically, this monitoring system covers the entire process from data acquisition to displacement calculation, including key aspects such as pipe pre-embedding, instrument deployment, and signal transmission. As concrete dams age, traditional settlement pipes often experience bending deformation or even damage due to dam creep, geological activity, and construction defects, rendering rigid monitoring equipment unable to pass through and creating monitoring gaps. Existing technologies typically employ structural repair solutions such as cement mortar injection or steel pipe replacement, but these methods require excavation, resulting in high construction costs (up to 3-5 times that of building a new system), the risk of damaging the main dam structure, and construction periods lasting several weeks, making it difficult to meet real-time monitoring needs.

[0003] However, existing pipeline repair methods directly use high-strength rigid materials for lining without considering the spatial adaptability of the pipeline after deformation. This can lead to poor bonding between the repair layer and the pipe wall or secondary blockage. Specifically, traditional repair processes typically employ high-pressure grouting or mechanical expansion, but these methods face technical bottlenecks such as uneven solution distribution and insufficient cross-linking reaction when dealing with complex deformed pipelines with small diameters (<100mm), long distances (>50m), and single ends. The cross-linking reaction mechanism of the PVA-borax gel system (e.g., Although it has applications in the field of materials science, its long-term stability in a closed water environment (such as...) remains to be seen. The dynamic complexation characteristics of PVA molecular chains have not been systematically studied. This technical limitation makes it difficult for existing repair methods to form a uniform waterproof layer, and the repaired pipeline still cannot meet the deployment requirements of subsequent monitoring equipment, ultimately leading to the failure of the monitoring system and affecting the timeliness and accuracy of dam safety early warning.

[0025] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein: Figure 1 This is a flowchart illustrating a method for repairing and automatically monitoring dam deformation settlement pipes according to an embodiment of the present invention.

Figure 3 This is a schematic diagram of a dam deformation settlement pipe repair and automated monitoring device provided in an embodiment of the present invention. Detailed Implementation

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] This invention provides a method for the repair and automated monitoring of dam deformation and settlement pipes. Figure 1 This is a flowchart illustrating a method for repairing and automating the monitoring of dam deformation and settlement pipes, provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the overall system for a method of repairing and automatically monitoring deformed settlement pipes in a dam, provided in an embodiment of the present invention. In this diagram, 1 represents the original deformed steel settlement pipe, 2 represents the PVA borax gel waterproof layer, 3 represents the variable diameter hose, 4 represents the submersible level gauge, 5 represents the data acquisition and transmission system, and 6 represents the dam body. Figure 1 , Figure 2 As shown, the method includes the following steps: Step S1: Prepare a polyvinyl alcohol solution and a borax crosslinking agent solution. Inject the two solutions into the deformable settling pipe by alternating injection. The polyvinyl alcohol solution forms a coating layer on the pipe wall and reacts with the borax solution to generate a gel-like waterproof inner lining layer attached to the pipe wall.

[0029] Specifically, in the settling pipe repair step of this invention, a polyvinyl alcohol (PVA) solution and a borax crosslinking agent solution are first prepared, and then injected alternately into the deformed settling pipe to form a gel-like waterproof inner lining layer. The core of this step lies in utilizing the crosslinking reaction between PVA and borax to repair and seal the inner wall of the pipe, thereby providing a reliable waterproof environment for the subsequent liquid level monitoring system.

[0030] At the technical implementation level, the PVA solution is prepared using fully alcoholyzed PVA (such as PVA-124) with a degree of alcoholysis greater than 99% to ensure sufficient reaction with the borax crosslinking agent. The concentration of the PVA solution is controlled at... Preferred This process aims to form a gel film of a certain thickness and strength while maintaining good fluidity. The dissolution process needs to be carried out within... The process is carried out at a specific temperature, and the solution is continuously stirred until it becomes clear and transparent, ensuring that no undissolved particles will affect the subsequent coating effect. The concentration of the borax crosslinking agent solution is controlled at [temperature value missing]. Preferred This is to regulate the rate of the cross-linking reaction and the gel hardness, avoiding excessively fast reactions that could cause blockage or excessively slow reactions that could affect the integrity of the membrane.

[0031] During the alternating injection process, the PVA solution is first slowly injected into the settling tube at a pressure of less than 0.5 MPa using a peristaltic pump or a low-pressure metering pump, ensuring uniform coating along the tube wall, especially forming a continuous coating layer in bends and damaged areas. Subsequently, a borax solution is injected, with a volume approximately 1 / 10 that of the PVA solution, to ensure sufficient but not excessive cross-linking reaction. The volume ratio of PVA to borax is controlled at 1:10, slightly higher than the theoretical stoichiometric ratio, thus guaranteeing complete cross-linking. After injection, the tube is allowed to stand for 3–5 minutes to allow the cross-linking reaction to fully proceed, forming a gel-like waterproof layer adhering to the tube wall. This process can be repeated more than three times to enhance the thickness and integrity of the waterproof layer, while avoiding significant reduction in the tube's inner diameter or damage to the underlying gel due to excessive injection.

[0032] At the chemical reaction level, borax hydrolyzes in water to generate tetrahydroxyborate ions. This ion acts as a crosslinking center, bonding with multiple hydroxyl groups on the PVA molecular chain through hydrogen bonds and coordination bonds. The ions combine to form diol complex ions, which in turn construct a three-dimensional network hydrogel. This gel exhibits excellent flexibility and is insoluble in water, effectively sealing cracks and corrosion pores in the settling pipe and preventing leakage.

[0033] In practical applications, this step is suitable for steel settling pipes that have been bent, deformed, or even slightly damaged, and it has significant advantages, especially in complex conditions involving small diameters, long distances, and single ports. Through a non-structural, low-cost chemical lining method, its monitoring function can be restored without excavation or pipe replacement. Simultaneously, the formed waterproof layer provides a stable, sealed environment for subsequently inserted variable-diameter hoses and level gauges, ensuring the long-term accuracy and reliability of level measurements.

[0034] In summary, this step, by precisely controlling the concentration and volume ratio of PVA and borax and the injection method, achieved efficient repair and waterproofing of deformed settlement pipes, laying a crucial foundation for subsequent automated settlement monitoring systems.

[0035] Furthermore, S1 includes: S11, control the concentration of the polyvinyl alcohol solution at... Within the specified range, the concentration of the borax crosslinking agent solution is controlled at... Within a certain range, to balance solution fluidity and gel strength.

[0036] Specifically, in the submerged tube repair process of this invention, the concentration of the polyvinyl alcohol (PVA) solution is controlled at [specific value]. Within the specified range, the concentration of the borax crosslinking agent solution is controlled at... Within this range, the formation of a stable waterproof membrane on the inner wall of the pipe is a crucial step. This step involves precisely controlling the concentrations of two solutions to create a gel-like liner with sufficient strength and flexibility within the pipe, thereby restoring and enhancing its functionality without damaging the original pipe structure.

[0037] From a technical perspective, the concentration of PVA solution, as the matrix material, directly affects the viscosity of the solution and the thickness of the gelled film. Within a given concentration range, PVA solutions exhibit moderate viscosity, allowing for smooth injection into long-distance, highly deformable pipelines via gravity and pumping, while also forming a gel film of considerable thickness and strength after the cross-linking reaction. The concentration of borax solution, acting as a cross-linking agent, determines the rate of the cross-linking reaction and the hardness of the gel. At certain concentrations, borax can undergo moderate cross-linking with the hydroxyl groups on the PVA molecular chain to form a three-dimensional network structure, thereby enhancing the mechanical properties and water resistance of the gel.

[0038] Regarding parameter indicators, if the concentration of the PVA solution is below 5%, the resulting gel film is too thin and difficult to effectively seal cracks; if it is above 6%, the viscosity is too high, affecting injection efficiency, especially causing flow resistance in areas of pipe bending or deformation. If the borax concentration is below 2%, the cross-linking reaction is insufficient, resulting in inadequate gel strength; if it is above 3%, the reaction is too fast, which may lead to premature gelation during injection, resulting in blockage or film embrittlement. Therefore, the preferred method of this invention is... PVA solution and The borax solution is injected alternately to achieve the best repair effect.

[0039] In practical applications, this step is suitable for repairing steel settlement pipes inside dams that have become bent, deformed, or even slightly damaged. Through low-pressure, slow injection combined with a static reaction, the PVA solution is allowed to fully wet the pipe wall. Subsequently, a borax solution is injected to trigger a cross-linking reaction, forming a continuous, dense waterproof membrane. This membrane not only effectively seals cracks and corrosion holes in the pipe but also provides a stable internal environment for subsequently inserted variable-diameter hoses and level gauges, preventing leakage that could lead to measurement failure.

[0040] From a technical perspective, this step achieves a balance between the fluidity and gel strength of the remediation material by precisely controlling the concentrations of PVA and borax. On the one hand, it ensures that the solution can be smoothly injected into pipes with complex shapes; on the other hand, it ensures that the formed gel film has sufficient mechanical strength and durability to remain stable in a long-term aquatic environment, thus providing a reliable foundation for subsequent automated settlement monitoring. This method has significant advantages in terms of construction efficiency, material cost, and remediation quality, and is the core element of this invention for achieving low-cost, highly adaptable remediation.

[0041] S12 controls the PVA dissolution temperature at 90-95℃, ensuring complete dissolution of PVA through high temperature and stirring, resulting in a clear and transparent solution.

[0042] Specifically, in some implementations, dissolving polyvinyl alcohol (PVA) in deionized water is one of the key steps in the sedimentation pipe repair method of this invention. This technique is based on the thermodynamic behavior and solution kinetics of the polymer material. PVA is a water-soluble polymer, and its dissolution process is significantly affected by temperature and stirring intensity. To ensure complete dissolution of PVA and the formation of a homogeneous, clear solution, the dissolution temperature should be strictly controlled within [temperature range missing]. Within this temperature range, the crystallinity of PVA molecular chains can be effectively reduced, and its dissolution rate and solubility in water can be increased, thereby avoiding problems such as turbidity or uneven gelation caused by incomplete dissolution.

[0043] The specific operation method is as follows: PVA powder (preferably PVA-124, with a degree of alcoholysis greater than 99%) is mixed according to the mass-volume ratio. Add to deionized water, place in a constant temperature water bath or heated stirring tank, and stir with a mechanical stirrer. Continue stirring at a constant speed until the solution is completely clear and transparent. This process typically requires... The specific time depends on the PVA batch, stirring efficiency, and total volume of solution. Clarity and transparency are important indicators of complete PVA dissolution, indicating that its molecular chains have fully extended and are uniformly dispersed in water, providing a good foundation for subsequent reactions with borax crosslinking agents.

[0044] From a technical perspective, PVA undergoes enhanced thermal motion of its molecular chains at high temperatures, breaking down its internal hydrogen bonds and promoting its interaction with water molecules. Stirring further breaks up PVA particle aggregation through shear force, accelerating its dissolution kinetics. This step plays a crucial role in the entire technical solution, directly affecting the uniformity of subsequent cross-linking reactions and the density of the waterproof membrane, thus determining the sealing performance of the repaired sedimentation pipe and the long-term stability of the monitoring system. Therefore, the temperature control, stirring method, and solution clarity in this step must all meet engineering construction standards to ensure the repeatability and reliability of the repair process.

[0045] Step S2: Insert the deformable hose into the repaired settling pipe. The outer diameter of the deformable hose is smaller than the minimum inner diameter of the repaired settling pipe, and an immersion level gauge is fixedly installed at its bottom. The power and signal cables of the level gauge are led out to the pipe opening through the inside of the hose.

[0046] Specifically, in the "deployment of variable diameter hose and level gauge" step of this invention, a deformable hose made of flexible material is used as the carrier of the level gauge. Its outer diameter is designed to be smaller than the minimum inner diameter of the repaired settling pipe to ensure that it can smoothly pass through any bends, deformations, or local narrow areas that may exist in the pipeline. This hose is preferably made of high-density polyethylene (HDPE) or reinforced polyvinyl chloride (PVC), which has good flexibility, water corrosion resistance, and a certain compressive strength. It can maintain structural stability in deep water environments and prevent the hose from being crushed by external water pressure, thus affecting the normal operation of the level gauge.

[0047] A high-precision submersible level transmitter is fixedly installed at the bottom of the hose. This level gauge calculates the water level by measuring the hydrostatic pressure of the fluid and is suitable for closed, deep well structures. Its sensing diaphragm must be directly exposed to the water to ensure measurement accuracy. The power and signal cables of the level gauge are led out from inside the hose to the pipe opening and sealed with a waterproof cable lock connector to prevent moisture from seeping into the cable interface and affecting the stability of long-term monitoring. An appropriate length of cable should be left at the pipe opening and secured to prevent the level gauge from detaching from the bottom of the pipe due to external pulling.

[0048] During installation, an annular space is formed between the flexible hose and the repaired settling pipe. This space is then filled with purified water, forming a closed "pressure measuring pipe" system. Through this system, the level gauge can sense changes in water pressure in real time and convert them into a water level value. Since water pressure and water depth have a linear relationship, i.e. ,in For hydrostatic pressure, The density of water, It is the acceleration due to gravity. The liquid level is the height of the liquid level gauge. Therefore, no matter how the settlement pipe is bent or deformed, as long as the position of the liquid level gauge is fixed, the measurement result can accurately reflect the vertical displacement of the settlement pipe, thereby achieving high-precision monitoring of dam settlement.

[0049] This step is crucial for achieving automated and continuous operation of the entire monitoring system. By embedding the level gauge into a deformable flexible hose and placing it at the bottom of the repaired settlement pipe, not only is the problem of traditional inclinometers or settlement gauges being unable to be inserted due to pipe deformation solved, but settlement measurement is also achieved through hydraulic principles, unaffected by the pipe's geometry. Its technological value lies in: reusing the disabled settlement pipe without damaging the original pipe structure, while ensuring the long-term stability of the measurement system and the high reliability of the data.

[0050] Furthermore, S2 includes: S21, the deformable hose is made of high-density polyethylene (HDPE) or polyurethane (PU), and its outer diameter is reserved with a gap of at least 10% from the minimum inner diameter of the repaired settlement pipe.

[0051] Specifically, in the second step of this invention, the installation of the deformable hose is a crucial step in ensuring the stable operation of the settlement monitoring system. This hose serves as the mounting carrier and protective structure for the level gauge, and its material selection and dimensional design must strictly match the internal conditions of the repaired settlement tube to ensure the system's adaptability and measurement accuracy in complex deformation environments.

[0052] In some implementations, deformable hoses are preferably made of high-density polyethylene (HDPE) or polyurethane (PU). Both materials possess excellent flexibility, water corrosion resistance, and a certain compressive strength, enabling them to adapt to bending, deformation, or even localized damage that may occur inside the submersible after repair. HDPE hoses have high chemical stability and abrasion resistance, making them suitable for long-term underwater environments; while PU hoses offer better elasticity and fatigue resistance, making them suitable for monitoring scenarios involving frequent micro-deformations.

[0053] Furthermore, the outer diameter of the hose must be designed to allow for a gap of at least 10% with the minimum inner diameter of the repaired settling pipe. This gap is based on both fluid mechanics and structural adaptability considerations. On the one hand, the gap reduces the frictional resistance of the hose during insertion, facilitating its passage through complex deformation sections; on the other hand, this gap provides space for subsequent water injection into the annular space between the hose and the settling pipe, ensuring that the water can freely fill and maintain a stable liquid level, thereby providing an accurate hydrostatic pressure measurement environment for the level gauge.

[0054] In practical operation, a high-precision submersible pressure level transmitter must be fixedly installed at the bottom of the hose, with its sensing diaphragm directly exposed to the water to ensure measurement accuracy. The power and signal cables of the level gauge are led out through the inside of the hose and sealed at the pipe opening with a waterproof cable lock connector to prevent water leakage or cable pull-out. During installation, the hose should be inserted slowly to avoid jamming or damage to the inner lining due to excessive speed.

[0055] This step plays a crucial role in the overall technical solution. On one hand, it relies on the PVA-borax gel waterproof layer formed in the previous step to provide a sealed and waterproof measurement environment for the level gauge. On the other hand, it provides the physical basis for subsequent automated settlement monitoring, enabling the level gauge to stably sense water level changes and thus accurately calculate the vertical displacement of the dam. By rationally selecting materials and dimensional parameters, this step effectively solves the technical problem of traditional settlement pipes being unable to deploy measuring equipment due to deformation, achieving the deployment of a low-cost, highly adaptable automated monitoring system.

[0056] S22, the bottom end of the hose is designed as a streamlined, open-ended protective head to ensure that the level gauge sensing diaphragm is directly exposed to the water.

[0057] Specifically, in the installation of variable diameter hoses and level gauges, the bottom end of the hose is designed as a streamlined, open, perforated protective head, which is one of the key structural designs for achieving accurate level gauge measurement. This design is based on fluid mechanics and sensor installation principles, aiming to ensure that the level gauge's sensing diaphragm can be directly exposed to the water, thereby accurately sensing changes in water pressure and achieving high-precision monitoring of the dam's vertical settlement.

[0058] In some implementations, the perforated protective head employs a streamlined structural design with a conical or hemispherical front end to reduce resistance when passing through the complex geometry inside the deformable settling tube. The streamlined design effectively reduces turbulence during fluid flow, preventing hose deformation or level gauge damage due to friction or jamming during installation. Simultaneously, the perforated structure ensures direct contact between the level gauge's sensing diaphragm and the water, avoiding measurement errors caused by closed or obstructed hose ends.

[0059] Furthermore, the perforated portion of the protective head typically employs a porous or mesh-like structure, with the aperture range controlled within a certain range. To prevent large particles from entering the level gauge while ensuring uniform water pressure transmission, a flexible hose is slowly inserted into the repaired settling pipe through a perforated protective head at its bottom until it reaches the bottom. The level gauge's cable is led out from inside the hose and fixed to the end of the hose, with its sensing diaphragm fully exposed to the water to ensure the stability and accuracy of the measurement signal.

[0060] This step plays a crucial role in the overall technical solution. Because the settlement pipe may contain bends, deformations, or even localized damage, traditional closed-end connectors are prone to jamming or failing to reach the bottom of the pipe. The streamlined, perforated protective head not only improves the hose's passageway but also ensures reliable installation of the level gauge in complex piping environments. Through this structural design, the system can achieve continuous, real-time monitoring of the water level within the settlement pipe, thereby accurately calculating the vertical displacement of the dam body and providing critical data support for dam safety assessment.

[0061] Step S3: Seal the annular space between the deformable hose and the settling pipe and inject pure water to form a closed pressure measuring tube structure, so that the level gauge can obtain water level data in real time by measuring water pressure changes.

[0062] Specifically, in the second step of this invention, a closed pressure-measuring tube structure is constructed by inserting a deformable flexible tube inside the repaired settlement tube, sealing the annular space between the flexible tube and the settlement tube, and then injecting pure water. This enables high-precision automated monitoring of dam settlement. The technical implementation of this step is based on a combination of fluid mechanics principles and modern liquid level sensing technology, exhibiting high engineering practicality and environmental adaptability.

[0063] In some implementations, the deformable hose used is typically a high-density polyethylene (HDPE) hose or a reinforced polyvinyl chloride (PVC) hose. These hoses possess good flexibility and pressure resistance, and their outer diameter must be significantly smaller than the minimum inner diameter of the repaired dropout tube to ensure that structural damage is not caused by jamming or friction during insertion. The hose is inserted slowly from the top opening of the dropout tube until it reaches the bottom. A submersible pressure-level transmitter is installed at the bottom of the hose, with its sensing diaphragm directly exposed to the water, for measuring hydrostatic pressure. The measurement accuracy of this level gauge is typically within [insert accuracy range here]. Within this range, the measurement range can be selected according to the depth of the settling pipe, for example, the pressure range of 0–500 kPa corresponding to a water depth of 0–50 m.

[0064] Furthermore, the annular space between the hose and the settling pipe needs to be sealed at the top to prevent external water or gas from entering and affecting measurement accuracy. The sealing method can employ a mechanical sealing joint or an elastic sealing ring to ensure an IP68 waterproof rating. Subsequently, pure water is injected into this annular space until it reaches the pipe opening, forming a closed water column system. At this point, the entire structure is equivalent to a vertical pressure measuring pipe, and the change in its internal water level is linearly related to the vertical displacement of the settling pipe.

[0065] From a technical perspective, the closed piezometer structure constructed in this step can convert dam settlement into water pressure changes measurable by the level gauge. Because water has a constant density, the hydrostatic pressure... ,in The density of water (approximately) ), The acceleration due to gravity (approximately) ), Since the water level is the liquid level, changes in water pressure directly reflect the vertical displacement. This method is unaffected by the bending or deformation of the settlement pipe, exhibiting high sensitivity and long-term stability, thus providing a reliable data foundation for dam safety monitoring.

[0066] Furthermore, S3 includes: S31 uses a waterproof cable lock connector to seal and fix the annular space between the hose and the sinking pipe, ensuring that the seal is absolutely waterproof.

[0067] Specifically, in some implementations, using a waterproof cable-locking connector to seal and fix the annular space between the hose and the settling pipe is one of the key steps in achieving long-term stable liquid level monitoring in this invention. The technical principle behind this step is based on the mechanical fixation and waterproof performance of the sealing connector, ensuring that the annular space between the hose and the settling pipe does not leak during subsequent water filling, thereby maintaining the integrity and measurement accuracy of the pressure measuring system.

[0068] The specific operating procedure is as follows: At the upper opening of the settling pipe, the annular space between the hose and the settling pipe is sealed using a dedicated waterproof cable lock connector. This connector typically consists of a polymer elastic sealing ring, a metal lock nut, and a waterproof sleeve. Its structural design meets the IP68 protection standard, enabling it to maintain sealing performance in long-term underwater environments. During installation, the hose is first inserted into the repaired settling pipe, connecting and securing its bottom to the level gauge. Then, the waterproof cable lock connector is fitted onto the connection between the hose and the settling pipe, and an appropriate torque (generally controlled within the range of 10-15 N·m) is applied using the threaded locking device to ensure a tight fit between the connector and the pipe wall, forming an effective sealing interface.

[0069] In terms of specifications, the sealing performance of the waterproof cable lock joint must meet a water pressure sealing requirement of at least 0.6 MPa to adapt to the potential water head pressure inside the dam. Simultaneously, the joint's corrosion resistance should comply with the GB / T12022-2008 standard "Waterproof Cable Seals" to ensure that it will not age or fail during long-term immersion in water (pH value approximately 6.5-7.5). Furthermore, the joint should be installed at the top opening of the settling pipe, consistent with the level gauge cable lead-out end, to facilitate subsequent cable laying and fixing.

[0070] In practical applications, this sealing process is typically carried out at the top of the settlement pipe inside the dam, in environments that may be humid, confined, or underwater. Therefore, the installation of the waterproof cable lock joint requires specialized tools to ensure a reliable seal even under complex conditions. This sealing structure not only prevents external water infiltration or internal water leakage but also provides the necessary conditions for subsequent injection of pure water into the annular space, creating a closed "pressure gauge" structure for the entire system.

[0071] From a technical perspective, this step, through the dual protection of mechanical seals and waterproof materials, effectively prevents water leakage during the monitoring process, thus ensuring that the hydrostatic pressure data measured by the level gauge accurately reflects the vertical displacement changes of the settlement pipe. Its sealing performance directly affects the long-term stability of the system and the continuity of data acquisition, and is a crucial guarantee for achieving automated, unattended settlement monitoring.

[0072] Step S4: Calculate the absolute vertical displacement of the settlement pipe based on the difference between the water level data and the initial reference water level value, record the displacement time series through the data acquisition system, and transmit the monitoring data to the remote monitoring center to achieve automated monitoring.

[0073] Specifically, in the automated settlement monitoring step, the system collects liquid level data inside the settlement pipe and calculates the difference between this data and the initial reference water level to obtain the absolute vertical displacement of the settlement pipe. This step is based on the principle of hydrostatics, which states that in a closed vertical pipe, the liquid level is linearly related to the hydrostatic pressure, thus directly converting changes in liquid level into vertical displacement.

[0074] In practical implementation, the submersible pressure level transmitter is fixedly installed at the bottom of a variable diameter hose, with its sensing diaphragm directly exposed to the water in the annular space for real-time water depth measurement. The measurement accuracy of the level gauge is typically within [specific range missing]. Within a certain range, the measurement range can be configured according to the length of the settling pipe, for example, 0–50m water depth. The measurement signal is transmitted via cable to the data acquisition system at the pipe opening. This system has a timed sampling function, and the sampling frequency can be set to 1 time / minute to 1 time / hour, depending on the monitoring requirements and system power consumption control strategy.

[0075] The water level time series data recorded by the data acquisition system is processed using the formula... Perform the difference calculation, where This represents the current water level. This is the initial reference water level value. The difference... This refers to the vertical displacement of the settlement tube, reflecting the settlement or uplift of the dam body at that point. To improve data reliability, the system can be configured with a multi-point benchmark calibration mechanism, such as resetting under different seasons or specific operating conditions. This is to eliminate the influence of non-structural factors such as ambient temperature and water expansion.

[0076] Monitoring data is transmitted to a remote monitoring center via wired or wireless communication methods (such as RS485, LoRa, 4G / 5G, etc.), enabling unattended automated monitoring. The system can integrate a solar power module to ensure long-term stable operation in remote areas or environments without power grid coverage. This step plays a crucial role in the entire technical solution, not only enabling continuous monitoring of the repaired settlement pipe, but also ensuring the real-time, continuous, and accurate nature of settlement data through the collaborative work of a high-precision level gauge and the data acquisition system, providing a reliable basis for the dam structure safety assessment.

[0077] Furthermore, S4 includes: The S41 transmits monitoring data to a remote monitoring center via wired or wireless transmission, enabling 24 / 7 unattended automated monitoring.

[0078] Specifically, in the automated settlement monitoring system of this invention, transmitting monitoring data to a remote monitoring center via wired or wireless transmission is a key step in achieving 24 / 7 unattended operation. This step, based on real-time water level data collected by a level gauge, combines a data acquisition system and a communication module to construct a stable, reliable, and low-power remote monitoring link.

[0079] At the technical implementation level, the level gauge measures hydrostatic pressure through its built-in piezoresistive sensor. This pressure value is proportional to the water depth, following the principles of hydrostatics. ,in For pressure, The density of water, It is the acceleration due to gravity. The signal represents the liquid level. The acquisition system performs analog-to-digital conversion (ADC) on this analog signal and encapsulates it according to a preset data format (such as Modbus RTU or CAN bus protocol), transmitting it via cable to a ground-based data acquisition unit. The acquisition unit has a built-in embedded processor that performs preliminary filtering, calibration, and timestamping on the data, forming standard water level time series data.

[0080] Regarding data transmission, this invention supports both wired and wireless methods. Wired transmission typically uses shielded twisted-pair cables to ensure signal integrity and anti-interference capabilities in complex electromagnetic environments. Wireless transmission can utilize low-power wide-area network (LPWAN) technologies such as LoRa, NB-IoT, or 4G / 5G, suitable for scenarios with limited communication infrastructure around dams. The data acquisition device has a built-in communication module that supports remote configuration and data uploading. Its transmission frequency can be set from once every 5 minutes to once per hour according to actual needs, balancing real-time performance and energy consumption control.

[0081] In terms of parameter settings, the data acquisition system needs to configure key parameters such as sampling rate, filtering coefficient, and communication baud rate. For example, the sampling rate can be set to... The filter coefficients are adopted A low-pass filter is used to eliminate the impact of transient fluctuations on settlement data. The communication baud rate is typically set to... This ensures stable data transmission. Furthermore, the system supports remote calibration, allowing the monitoring center to correct the zero point and full scale of the level gauge based on historical data or on-site calibration results, thus improving long-term monitoring accuracy.

[0082] In application scenarios, this step is widely applicable to settlement monitoring systems for civil engineering structures such as dams, embankments, and bridges. Especially in remote areas or unattended sites, wireless transmission significantly reduces cabling costs and maintenance complexity. Through centralized management at a remote monitoring center, functions such as multi-point data fusion analysis, anomaly warning, and trend prediction can be achieved, providing real-time and continuous data support for engineering safety assessments.

[0083] The technological value of this step lies in ensuring the integrity and traceability of settlement data through standardized data encapsulation and transmission mechanisms. Simultaneously, combined with a remote monitoring platform, it achieves an automated and intelligent monitoring process. Its innovation lies in combining traditional liquid level measurement with modern communication technology, providing a complete closed-loop solution for the reuse of old, deformed settlement pipes.

[0084] Step S5: Use an endoscope to check the local effect of the waterproof membrane liner after each alternating injection. Based on the inspection results, decide whether to increase the number of alternating injections to ensure that the waterproof membrane has a uniform thickness and completely covers all defects and rust holes.

[0085] Specifically, in the settlement pipe repair process of this invention, the step of "using an endoscope to check the local effect of the waterproof membrane liner after each alternating injection, and deciding whether to increase the number of alternating injections based on the inspection results" is a key control link to ensure repair quality and the long-term stable operation of the monitoring system. This step is based on real-time quality assessment of the waterproof membrane liner formed by the PVA-borax gel reaction, thereby dynamically adjusting the repair process parameters to achieve the repair goal of uniform thickness and complete coverage of all defects and rust holes.

[0086] At the technical implementation level, this step employs an industrial endoscope for visual inspection of the interior of the settling pipe. Endoscopes typically feature high-resolution CCD image sensors, adjustable illumination systems, and flexible probes, allowing them to penetrate deep into pipes, making them particularly suitable for complex pipeline structures with bends, deformations, or localized damage. After each alternating injection of PVA solution and borax solution, the endoscope probe is slowly inserted into the upper port of the settling pipe, performing a 360° scan along the pipe wall to observe the adhesion, thickness distribution, and coverage of all defective areas of the waterproof membrane. If areas are found to be too thin, incompletely cured, or have uncovered rust pits, the number of alternating injections can be increased to supplement the membrane thickness and enhance sealing performance.

[0087] Regarding parameters, the frequency of endoscopic examinations should be synchronized with the number of alternating injections. It is recommended to check after each injection, allowing the area to stand for 3-5 minutes to ensure the initial cross-linking reaction is complete. The thickness of the waterproof membrane can be estimated using image analysis software; the ideal thickness range is [insert range here]. Too thin ( This may lead to insufficient sealing, or excessive thickness. This could affect the subsequent insertion of the hose and the normal operation of the level gauge. Furthermore, the volume ratio of PVA to borax should be controlled within a certain range. This ensures sufficient cross-linking without premature gelation.

[0088] In application scenarios, this step is particularly suitable for steel settlement pipes pre-embedded inside dams, which typically have limitations such as single-port design, long distance, small diameter, and internal deformation. Through real-time feedback from the endoscope, construction personnel can flexibly adjust the number of repairs without damaging the dam structure, ensuring that the membrane quality meets the installation requirements of subsequent liquid level monitoring systems.

[0089] The technical advantage of this step lies in its significantly improved adaptability and reliability of the remediation process through a closed-loop control mechanism. Traditional remediation methods often rely on experience-based judgment, making it difficult to ensure the uniformity and integrity of the membrane layer. This invention, however, utilizes real-time endoscopic monitoring combined with quantitative indicators for decision-making, effectively avoiding the risk of leakage due to membrane defects, thereby ensuring the long-term accuracy and stability of the settlement monitoring system.

The displacement calculation and data transmission module 400 is used to calculate the absolute vertical displacement of the settlement pipe based on the difference between the water level data and the initial reference water level value, record the displacement time series through the data acquisition system, and transmit the monitoring data to the remote monitoring center to realize automated monitoring.
