[0023] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.

[0024] An automated monitoring structure for monitoring ground subsidence using a stratified settlement meter includes a monitoring hole 10, an isolation tube 20, a stratified settlement monitoring mechanism 30, and a data acquisition and transmission device 50 connected to the stratified settlement monitoring mechanism 30. The monitoring hole 10 is located above the potential hazard point in the stratum to be monitored. The isolation tube 20 is vertically installed inside the monitoring hole 10, and a backfill soil layer 11 is filled between the outer wall of the isolation tube 20 and the hole wall of the monitoring hole 10. The stratified settlement monitoring mechanism 30 includes multiple magnetic rings 31 and multiple magnetostrictive stratified settlement sensors 32. The magnetostrictive stratified settlement sensors 32 and the magnetic rings 31 are arranged at intervals relative to each other. The multiple magnetic rings 31 are spaced apart along the axial direction of the isolation tube 20 and are fixedly connected to the backfill soil layer 11 at the corresponding depth. A core rod 40 is installed inside the isolation tube 20, and the multiple magnetostrictive stratified settlement sensors 32 are spaced apart along the axial direction of the core rod 40 to detect the vertical displacement of the magnetic rings 31.

[0025] The aforementioned automated monitoring structure for monitoring ground subsidence using a stratified settlement gauge constructs a complete automated ground subsidence monitoring system by setting up a monitoring hole 10, an isolation tube 20, a stratified settlement monitoring mechanism 30, and a data acquisition and transmission device 50. The monitoring hole 10 precisely corresponds to the potential hazard points in the ground to be monitored, providing a foundation for the subsequent installation of monitoring components. The isolation tube 20 is vertically installed inside the monitoring hole 10, and the backfill soil layer 11 between its outer wall and the hole wall can fix the position of the isolation tube 20, while preventing the hole wall from collapsing and affecting monitoring, effectively protecting the internal monitoring components. In the stratified settlement monitoring mechanism 30, multiple magnetic rings 31 correspond to... The backfill soil layer 11 is fixed at a certain depth and can move vertically synchronously with the settlement of the stratum. Multiple magnetostrictive stratified settlement sensors 32 are spaced apart along the axial direction of the core rod 40, which can accurately detect the displacement of each magnetic ring 31 and realize stratified monitoring of settlement at different depths, breaking the limitation of traditional monitoring that is difficult to accurately stratify. The data acquisition and transmission device 50 is connected to the magnetostrictive stratified settlement sensor 32, which can automatically collect and transmit monitoring data without the need for frequent manual on-site collection, greatly improving monitoring efficiency and timely obtaining stratum settlement information, providing data support for stratum collapse early warning, and reducing the risk of delayed early warning due to untimely manual collection.

[0026] The backfill layer 11 can be made of yellow sand and placed inside the monitoring hole 10.

[0027] In this embodiment, the isolation tube 20 is coaxially fixed inside the monitoring hole 10, and the magnetic ring 31 is coaxially arranged with the isolation tube 20.

[0028] The isolation tube 20 is fixed coaxially with the monitoring hole 10, and the magnetic ring 31 is arranged coaxially with the isolation tube 20. This ensures that the isolation tube 20 is centered within the monitoring hole 10, preventing excessive compression or large gaps between the isolation tube 20 and the hole wall due to installation misalignment. This ensures that the backfill soil layer 11 is evenly filled between the outer wall of the isolation tube 20 and the hole wall, further improving the installation stability of the isolation tube 20. Simultaneously, the coaxiality of the magnetic ring 31 with the isolation tube 20 allows the magnetic ring 31 to move smoothly along the axial direction of the isolation tube 20. This prevents deviations in the detection by the magnetostrictive stratified settlement sensor 32 due to magnetic ring 31 misalignment, ensuring the accuracy of the magnetic ring 31's displacement detection and laying the foundation for the accuracy of subsequent stratified settlement data.

[0029] In this embodiment, the inner wall of the magnetic ring 31 is slidably connected to the outer wall of the isolation tube 20, and the outer wall of the magnetic ring 31 is spaced apart from the wall of the monitoring hole 10.

[0030] The inner wall of the magnetic ring 31 is slidably connected to the outer wall of the isolation tube 20. This connection does not affect the vertical displacement of the magnetic ring 31 as the formation settles, while the isolation tube 20 guides the movement of the magnetic ring 31, preventing lateral deviation during displacement and ensuring that the magnetic ring 31 always moves in the set direction. This guarantees that the displacement data detected by the magnetostrictive stratification settlement sensor 32 accurately reflects the formation settlement. The outer wall of the magnetic ring 31 is spaced apart from the wall of the monitoring hole 10, avoiding direct contact between the magnetic ring 31 and the hole wall. This prevents unevenness or impurities on the hole wall from hindering the movement of the magnetic ring 31, reducing its resistance and further ensuring the smoothness of the magnetic ring 31's displacement and the reliability of the detection data.

[0031] In this embodiment, the core rod 40 is coaxially fixed inside the isolation tube 20.

[0032] The core rod 40 is coaxially fixed inside the isolation tube 20, keeping it centered within the tube and preventing it from shifting, which could cause the magnetostrictive stratification settlement sensor 32, which is installed along its axial direction, to shift. This ensures that each magnetostrictive stratification settlement sensor 32 maintains a set relative distance from its corresponding magnetic ring 31, preventing misalignment between the sensor and the magnetic ring 31 due to core rod 40 shift. This ensures that the sensor can accurately detect the vertical displacement of the magnetic ring 31, further improving the accuracy of stratification settlement monitoring data and preventing monitoring results from being affected by improper installation of the core rod 40.

[0033] In this embodiment, the bottom of the isolation tube 20 is closed, the bottom of the isolation tube 20 abuts against the bottom of the monitoring hole 10, and the top of the isolation tube 20 is above the ground.

[0034] The isolation tube 20 is enclosed at the bottom and abuts against the bottom of the monitoring hole 10. This prevents mud, sand, groundwater, and other contaminants from entering the isolation tube 20, thus avoiding contamination or corrosion of internal components such as the core rod 40 and the magnetostrictive stratification sensor 32, extending their service life, and preventing impurities from affecting the normal operation of the sensor, ensuring monitoring stability. The top of the isolation tube 20 is raised above the ground. This allows personnel to easily install, maintain, and repair the relevant components on the top of the isolation tube 20 from the ground without having to enter the monitoring hole 10, reducing operational difficulty and safety risks. Furthermore, it prevents rainwater and debris from entering the isolation tube 20, further protecting the internal monitoring components and ensuring the long-term stable operation of the monitoring system.

[0035] In this embodiment, the bottom of the isolation tube 20 is arranged in a conical shape.

[0036] When installing the isolation tube 20, the conical bottom allows for easier insertion into the bottom of the monitoring hole 10, providing excellent positioning and quickly determining the installation location of the isolation tube 20, thus improving installation efficiency. Simultaneously, the small contact area between the conical structure and the bottom of the monitoring hole 10 ensures a more stable fixation at the bottom of the hole. During the backfilling process of the soil layer 11, it effectively resists the lateral thrust of the soil layer on the isolation tube 20, preventing it from tilting and ensuring that the isolation tube 20 remains vertical. This provides a stable installation foundation for the normal operation of the magnetic ring 31 and the magnetostrictive stratification settlement sensor 32, guaranteeing the accuracy of the monitoring data.

[0037] In this embodiment, a fixing collar 41 is installed on the top of the core rod 40 to seal the top opening of the isolation tube 20, and the core rod 40 is detachably connected to the isolation tube 20 through the fixing collar 41.

[0038] The retaining collar 41 at the top of the core rod 40 can seal the top opening of the isolation tube 20, preventing external dust, rainwater, debris, etc. from entering the interior of the isolation tube 20. This protects the internal components such as the core rod 40 and the magnetostrictive stratification sensor 32, preventing damage or performance degradation, extending the service life of the monitoring system, and ensuring continuous and stable monitoring. The core rod 40 is detachably connected to the isolation tube 20 via the retaining collar 41. When it is necessary to inspect or replace the core rod 40 or the magnetostrictive stratification sensor 32, the retaining collar 41 can be easily removed, and the core rod 40 can be taken out of the isolation tube 20 without damaging the overall structure of the isolation tube 20. This reduces maintenance costs, improves maintenance efficiency, and facilitates future upgrades and modifications to the monitoring system.

[0039] In this embodiment, the data acquisition transmitter 50 includes a data acquisition terminal and a cloud monitoring platform. The data acquisition terminal is electrically connected to each magnetostrictive stratification sedimentation sensor 32 and is signal-connected to the cloud monitoring platform. The data acquisition transmitter 50 is connected to a power supply device 60.

[0040] The data acquisition and transmission unit 50 includes a data acquisition terminal and a cloud monitoring platform. The data acquisition terminal is electrically connected to each magnetostrictive stratification settlement sensor 32, enabling efficient collection of displacement data detected by each sensor and avoiding errors and delays associated with manual data collection. The data acquisition terminal is signal-connected to the cloud monitoring platform, allowing real-time transmission of the collected data to the cloud. Staff can remotely view the monitoring data through the cloud monitoring platform without needing to visit the monitoring site, achieving remote real-time monitoring of ground subsidence and significantly improving monitoring convenience and timeliness. When abnormal monitoring data is detected, staff can promptly identify it through the cloud platform, gaining more time for ground subsidence early warning. The power supply unit 60 provides power to the magnetostrictive stratification settlement sensors 32 and the data acquisition terminal, ensuring continuous and stable operation of all electrical components and preventing monitoring interruptions due to power outages, thus guaranteeing the continuity and reliability of the monitoring system.

[0041] In this embodiment, the power supply equipment 60 includes a solar photovoltaic panel and a storage battery. The solar photovoltaic panel and the storage battery are electrically connected, and the storage battery is electrically connected to the magnetostrictive stratification sedimentation sensor 32 and the data acquisition terminal, respectively.

[0042] The power supply equipment 60 uses a combination of solar photovoltaic panels and batteries. The solar photovoltaic panels can convert solar energy into electrical energy to charge the batteries, which in turn power the magnetostrictive stratification sensor 32 and the data acquisition terminal. This fully utilizes renewable energy and reduces dependence on traditional power grids. It is especially suitable for monitoring areas in remote areas with inconvenient grid coverage, solving the power supply problem for monitoring equipment in such areas.

[0043] In this embodiment, the top of the isolation pipe 20 is provided with a fixing structure 70 for fixing the isolation pipe 20 to the ground.

[0044] The fixing structure 70 at the top of the isolation tube 20 can relatively fix the isolation tube 20 to the ground, further enhancing the installation stability of the isolation tube 20. During daily monitoring, it can resist the influence of external factors such as wind and ground vibration on the isolation tube 20, preventing the isolation tube 20 from tilting or shifting, ensuring that the isolation tube 20 always remains in a vertical position, providing a stable foundation for the normal operation of internal components such as the magnetic ring 31 and the magnetostrictive stratification settlement sensor 32, and avoiding monitoring data deviation caused by the movement of the isolation tube 20. At the same time, the fixing structure 70 can protect the top of the isolation tube 20, reduce damage to the isolation tube 20 from accidental external impacts, extend the service life of the isolation tube 20, and ensure the long-term stable operation of the entire monitoring system.

[0045] The fixed structure 70 includes a ground fixing frame, which is fixed at the opening of the monitoring hole 10, and the top of the isolation tube 20 is detachably connected to the ground fixing frame.

[0046] The ground-mounted bracket is directly fixed to the opening of the monitoring hole 10, providing precise radial restraint and vertical support for the top of the isolation pipe 20. This prevents the isolation pipe 20 from tilting or shifting due to external wind, ground vibration, or slight settlement of the backfill soil layer 11. Compared to structures without hole-mounted brackets, this design ensures that the isolation pipe 20 remains vertical for extended periods, providing a stable reference for the relative positions of the internal core rod 40, the magnetostrictive stratified settlement sensor 32, and the magnetic ring 31. This prevents systematic errors in the displacement detection of the magnetic ring 31 caused by verticality deviations of the isolation pipe 20, ensuring the accuracy of the stratified settlement monitoring data.

[0047] The fixed structure 70 includes a reinforcing bar, one end of which is fixedly connected to the isolation pipe 20, and the other end of which is embedded in the ground. The reinforcing bar is fixed to the ground by concrete pouring to form a fixed layer.

[0048] The reinforcing bars are fixed to the ground by pouring concrete. After the concrete hardens, it forms a tightly integrated structure with the reinforcing bars and the surrounding soil. On the one hand, this completely eliminates the gaps between the reinforcing bars and the soil, preventing rainwater and groundwater from seeping into the gaps and causing corrosion of the reinforcing bars, or loosening of the fixed structure due to soil erosion. On the other hand, concrete has high strength, weather resistance, corrosion resistance, and frost heave resistance, which can maintain the anchorage strength of the reinforcing bars for a long time. Even in long-term harsh environments (such as rainy, cold, and soil salinization areas), it can prevent the fixed structure from failing due to environmental factors.

[0049] In this embodiment, a plurality of limiting rings 21 are sleeved on the outer wall of the isolation tube 20. The plurality of limiting rings 21 are spaced apart along the axial direction of the isolation tube 20 and are located above the magnetic ring 31 at the corresponding depth.

[0050] When the isolation tube 20 is below the monitoring hole 10, it can prevent the magnetic ring 31 from touching the inner wall of the monitoring hole 10 and being in an upward position, thus preventing the magnetic rings 31 from interfering with each other and causing positional disorder, and ensuring that each magnetic ring 31 is always within the preset monitoring depth range.

[0051] During the process of filling the backfill soil layer 11 into the monitoring hole 10, the limiting ring 21 can resist the impact force from the backfill soil layer 11 on the magnetic ring 31, and prevent the magnetic ring 31 from settling during the backfilling process.

[0052] When significant subsidence occurs in the strata, as the magnetic ring 31 slides downward with the strata, the limiting ring 21 can block the magnetic ring 31, preventing it from approaching or even colliding with the magnetic ring 31 at a higher depth due to excessive subsidence. This prevents the magnetic rings 31 from interfering with each other and causing misalignment, ensuring that each magnetic ring 31 is always within the preset monitoring depth range. This guarantees the independence and accuracy of subsidence data at each depth and avoids the misalignment of the magnetic ring 31 affecting the judgment of monitoring results.

[0053] In this embodiment, the magnetic ring 31 has multiple anchors 311 protruding outwards on its outer side. The multiple anchors 311 are arranged at intervals around the circumference of the magnetic ring 31. The anchors 311 are arranged horizontally. The outer wall of the magnetic ring 31 is fixedly connected to the backfill soil layer 11 at the corresponding depth through the anchors 311. The bottom of the anchors 311 has multiple inclined pull tabs 312 protruding downwards. The multiple inclined pull tabs 312 are arranged at intervals along the length direction of the anchors 311.

[0054] The bottom of the inclined pull tab 312 has an upwardly curved end 314, which forms a V-groove 315 with the inclined pull tab 312. The V-groove 315 is located directly below the anchor 311.

[0055] The outer wall of the magnetic ring 31 is connected to multiple limiting connecting strips 313. The multiple limiting connecting strips 313 are arranged at intervals around the circumference of the magnetic ring 31. The lower part of the limiting connecting strip 313 is connected to the magnetic ring 31, the upper part of the limiting connecting strip 313 is connected to the outer wall of the isolation tube 20, and the middle part of the limiting connecting strip 313 is arranged in a relaxed state.

[0056] When the stratum at the corresponding depth settles, the magnetic ring 31, which is fixedly connected to the backfill layer 11, will be straightened in the middle of the limiting connecting band 313 as the magnetic ring 31 settles. When the magnetic ring 31 settles to the set position, the magnetic ring 31 will be held in place by the limiting connecting band 313 to prevent the magnetic ring 31 from colliding with other magnetic rings 31.

[0057] The structure of the anchor 311 and inclined pull tab 312 on the outside of the magnetic ring 31 can greatly enhance the connection between the magnetic ring 31 and the backfill soil layer 11. The anchor 311 is horizontally arranged and can be embedded into the backfill soil layer 11, while the V-shaped groove 315 of the inclined pull tab 312 can further clamp the soil layer to prevent the magnetic ring 31 from separating from the backfill soil layer 11 and ensure that the magnetic ring 31 settles synchronously with the stratum. Furthermore, the inclined pull tab 312 and the bent end 314 are located below the anchor 311, which can reduce the resistance of the backfill soil layer 11 during the backfilling process, thereby preventing the magnetic ring 31 from sinking during the backfilling process of the backfill soil layer 11.

[0058] The limiting connecting band 313 is in a relaxed state when the magnetic ring 31 is settling normally, which does not affect the movement of the magnetic ring 31. When the magnetic ring 31 settles to the set position, the connecting band is straightened and holds the magnetic ring 31, which effectively prevents the magnetic ring 31 from colliding with other magnetic rings 31 due to excessive settlement, avoids the magnetic ring 31 from being misaligned or damaged, ensures the independence and stability of the monitoring function of each magnetic ring 31, and further improves the data accuracy and equipment safety of the entire monitoring system.

[0059] The data acquisition terminal includes a data acquisition module, a data processing module, and a wireless communication module. The data acquisition module is electrically connected to the magnetostrictive stratification sedimentation sensor 32, the data processing module is electrically connected to the data acquisition module, and the wireless communication module is electrically connected to the data processing module.

[0060] The wireless communication module adopts 4G / 5G or LoRa communication protocols;

[0061] The cloud-based monitoring platform includes a data storage unit, a data comparison and analysis unit, and an early warning unit. The data storage unit stores monitoring data, the data comparison and analysis unit compares real-time data with safety thresholds, and the early warning unit sends early warning information when data is abnormal.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
