It mostly focuses on single-point monitoring of the ground surface and cannot obtain deformation data of deep strata, making it difficult to predict the risk of collapse in advance. Furthermore, it relies on manual periodic measurement and recording of data, which results in data lag and large human errors, failing to meet the real-time early warning needs for sudden hidden dangers.

[0021] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.

[0022] An automated monitoring structure for monitoring ground subsidence using a hydrostatic level 40 includes at least two monitoring holes 10 at different depths, and an isolation tube 20, a stratification marker 30, a data acquisition instrument 70, a power supply device 80, and a monitoring and early warning cloud platform installed in each monitoring hole 10. The monitoring holes 10 are located above the area of ​​potential ground subsidence points. The isolation tube 20 is fixedly installed inside the monitoring hole 10 and has an internal cavity 21 that runs vertically through it. The stratification marker 30 is vertically installed in the internal cavity 21, and the bottom of the stratification marker 30 is connected to the bottom of the monitoring hole 10. The top of the stratification marker 30 is equipped with a hydrostatic level 40, which is used to monitor the change in elevation between the ground and the strata. Multiple static level instruments 40 are electrically connected to the data acquisition instrument 70 via wires to collect data on the elevation difference between the ground and the strata; the power supply equipment 80 is connected to the data acquisition instrument 70 and the static level instruments 40 to provide power; the data acquisition instrument 70 is communicatively connected to the monitoring and early warning cloud platform.

[0023] The automated monitoring structure for monitoring ground subsidence using a hydrostatic level 40, as described above, can simultaneously acquire elevation difference data from the surface to deeper strata by setting at least two monitoring holes 10 at different depths and using vertically fixed stratification markers 30. This solves the problem that traditional monitoring can only cover the surface and cannot capture early signs of deep subsidence. The hydrostatic level 40 directly collects elevation difference data, which is automatically summarized and uploaded to the monitoring and early warning cloud platform by the data acquisition instrument 70, eliminating the need for manual on-site recording, avoiding human error, and enabling real-time early warning of subsidence risks. The isolation pipe 20 provides an independent protective space for the stratification markers 30, preventing the collapse of the monitoring hole 10 walls and direct contact of stratum debris with the markers, ensuring that the markers always deform synchronously with the target monitored stratum, and improving the reliability of the monitoring data.

[0024] In this embodiment, multiple hydrostatic levels 40 are connected in series via liquid-passing pipes 50.

[0025] After multiple hydrostatic levels 40 are connected in series through liquid pipes 50, the internal liquids are connected to form a unified liquid level surface, eliminating the reference deviation when a single instrument is running independently, and making the height difference data of monitoring holes 10 at different depths directly comparable. The series structure reduces monitoring errors caused by inconsistent initial benchmarks of various static levels, improves the consistency of data from multiple monitoring points, and more accurately reflects the stratification differences in formation deformation.

[0026] In this embodiment, the hydrostatic level 40 includes a liquid storage tank 41 for storing liquid. A liquid level sensor for monitoring the liquid level is installed in the liquid storage tank 41. The liquid level sensor is electrically connected to the data acquisition instrument 70 through a wire. The liquid storage tanks 41 of multiple hydrostatic levels 40 are connected in series through a liquid passage pipe 50. The liquid storage tank 41 is snapped onto the top of the layered marker 30 by a mounting plate 42.

[0027] The liquid level sensor inside the storage tank 41 directly monitors the liquid level. Compared with traditional mechanical measurement methods, it has higher data resolution and smaller error, can capture minute changes in liquid level, and can identify minute displacements in the formation, thus improving monitoring sensitivity. The liquid storage tank 41 is snapped onto the top of the layered marker 30 by the mounting plate 42, which is convenient to install and flexible to disassemble, and facilitates later maintenance. Multiple liquid storage tanks 41 are connected in series by the liquid passage pipe 50 to form a stable communicating vessel structure, ensuring the correlation of liquid levels in each hydrostatic level 40, and providing a reliable basis for subsequent liquid level difference calculation.

[0028] Each static level 40 measures using the elevation of the local ground as a reference point, allowing for direct monitoring of deep settlement in the area. The static level 40 transmits the settlement data of the stratified benchmark 30 to the data acquisition unit 70 via a liquid level sensor. The data acquisition unit 70, in conjunction with the monitoring and early warning cloud platform, can investigate historical settlement records to determine which area's static level 40 experienced settlement.

[0029] In this embodiment, a level calibrator is provided on the mounting plate 42. The level calibrator is used to calibrate the installation level of the hydrostatic level 40.

[0030] The level calibrator can calibrate the static level instrument's 40° installation level in real time, avoiding distortion of liquid level data due to equipment tilt, and further ensuring the accuracy of monitoring data.

[0031] In this embodiment, the layered marker 30 is arranged coaxially with the isolation tube 20, and the outer circumferential direction of the layered marker 30 is spaced apart from the inner circumferential direction of the isolation tube 20. The bottom of the layered marker 30 is provided with a plurality of protrusions 31 facing downward, and the layered marker 30 is inserted into the bottom of the monitoring hole 10 through the plurality of protrusions 31.

[0032] The internal cavity 21 of the isolation tube 20 is arranged coaxially and spaced apart from the stratification marker 30, providing an independent vertical movement space for the stratification marker 30, avoiding friction or jamming between the stratification marker 30 and the inner wall of the isolation tube 20, and ensuring that the stratification marker 30 can settle or rise synchronously with the target stratum, truly reflecting the stratum displacement state; Multiple protrusions 31 at the bottom of the stratified marker 30 are inserted into the bottom of the monitoring hole 10, which can firmly anchor the stratum to be monitored, prevent the stratified marker 30 from detaching from the stratum, avoid monitoring data deviation caused by the marker loosening, and ensure that the data can be accurately correlated with the displacement of the target stratum.

[0033] In this embodiment, the diameter of the layered marker 30 gradually decreases along the direction from the middle to the top of the layered marker 30, and the top of the layered marker 30 is exposed outside the top of the isolation tube 20.

[0034] The diameter of the stratification marker 30 gradually decreases from the middle to the top, which can further reduce the contact area with the inner cavity 21 of the isolation tube 20 (if a slight displacement occurs), reduce frictional resistance, ensure the flexibility of the stratification marker 30 when it moves with the formation, and avoid displacement data lag or distortion caused by friction. The top of the layered marker 30 is exposed outside the isolation tube 20, allowing the static level 40 to be installed directly without the need to disassemble the isolation tube 20. This simplifies the installation process and facilitates the later inspection and replacement of the static level 40, improving equipment maintenance efficiency.

[0035] In this embodiment, the isolation tube 20 and the monitoring hole 10 are arranged coaxially. The top of the isolation tube 20 is exposed on the ground, and a protective cover 22 is installed on the top of the isolation tube 20. The protective cover 22 is detachably connected to the isolation tube 20. A through hole is opened in the middle of the protective cover 22 for the top of the layered marker 30 to pass through.

[0036] The protective cover 22 can effectively block rainwater, dust and debris from entering the interior of the isolation tube 20, preventing corrosion or blockage of the inner wall of the layered marker 30 and the isolation tube 20, extending the service life of the equipment and reducing monitoring failures caused by environmental factors. The through hole in the middle of the protective cover 22 allows the top of the stratification marker 30 to pass through, which does not affect the displacement of the stratification marker 30 with the stratum, and can also achieve the protective function, so that "protection" and "monitoring" do not interfere with each other; in addition, the protective cover 22 can also guide the settlement of the top of the stratification marker 30 and prevent its upper part from tilting.

[0037] In this embodiment, multiple displacement marks are spaced along the length of the top of the layered marker 30, and reading windows are provided on the inner wall of the isolation tube 20 corresponding to the displacement marks. Transparent wear-resistant glass is installed at the reading windows. In this way, the position of the displacement marks can be manually read and compared with the automatically collected liquid level difference data to verify the accuracy of the automated data, avoid erroneous data caused by equipment failure, and improve the reliability of the monitoring system.

[0038] In this embodiment, the power supply device 80 includes a solar panel, a battery, and a charging controller. The solar panel is electrically connected to the battery through the charging controller, and the battery is electrically connected to the data acquisition unit and the hydrostatic level 40, respectively.

[0039] Solar panels can generate electricity using natural sunlight in the wild, without relying on the power grid, solving the power supply problem in remote areas prone to subsidence (such as mining areas and mountainous areas), and enabling long-term continuous monitoring; batteries can store solar energy and power the equipment on cloudy days, at night, or when there is insufficient sunlight, avoiding the loss of monitoring data due to power outages; the charging controller can automatically adjust the charging current and voltage to prevent the battery from being overcharged or over-discharged, extending the battery's lifespan and reducing the maintenance cost of the power supply system.

[0040] In this embodiment, a reinforcing sleeve 60 is provided on the wall of the monitoring hole 10. The outer wall of the reinforcing sleeve 60 is in contact with the wall of the monitoring hole 10. A buffer cavity 61 is formed between the inner wall of the reinforcing sleeve 60 and the outer wall of the isolation tube 20. The buffer cavity 61 is filled with an elastic buffer layer.

[0041] The reinforced casing 60 can support the borehole wall of monitoring borehole 10, preventing the monitoring borehole 10 from collapsing due to loose strata or precipitation, protecting the internal isolation pipe 20 and the stratification marker 30, ensuring the structural integrity of the monitoring system, and preventing monitoring interruption due to borehole wall collapse; The elastic buffer layer can absorb external environmental vibrations (such as vehicle traffic and construction disturbances) or minor ground disturbances, preventing these disturbances from being transmitted to the stratification benchmark 30. This prevents the stratification benchmark 30 from generating false deformations of non-target ground displacements, ensuring that the monitoring data only reflects the target ground displacement and improving the authenticity of the data.

[0042] In this embodiment, the top of the reinforcing sleeve 60 is provided with a fixing structure 63 for fixing the reinforcing sleeve 60 to the ground. The fixing structure 63 includes a reinforcing rib 631. One end of the reinforcing rib 631 is fixedly connected to the reinforcing sleeve 60, and the other end of the reinforcing rib 631 is fixed to the ground by concrete pouring to form a fixing platform 632. The outer edge of the top of the reinforcing sleeve 60 is provided with an annular limiting plate 64 protruding outward, and the bottom of the annular limiting plate 64 is embedded in the top of the fixing platform 632. The inner top and inner bottom edges of the reinforcing sleeve 60 are provided with annular cover plates 65 for sealing the upper and lower openings of the buffer cavity 61. The inner diameter of the annular cover plate 65 is smaller than the outer diameter of the isolation tube 20. The annular cover plate 65 is fixedly connected to the inner wall of the reinforcing sleeve 60.

[0043] The reinforcing bar 631, in conjunction with the concrete fixing platform 632, can firmly fix the reinforcing sleeve 60 to the ground, preventing the reinforcing sleeve 60 from shifting or tilting, thereby ensuring the stability of the isolation pipe 20 and the layered benchmark 30, avoiding the shift of the monitoring benchmark caused by the movement of the reinforcing sleeve 60, and ensuring the continuity of monitoring data.

[0044] The annular cover plates 65 at the top and bottom of the reinforcing sleeve 60 can seal the upper and lower openings of the buffer cavity 61, preventing rainwater and mud from entering the buffer cavity 61 and contaminating the elastic buffer layer, thus avoiding the failure of the elastic buffer layer. At the same time, the inner diameter of the annular cover plate 65 is smaller than the outer diameter of the isolation pipe 20, which can form a vertical limit on the isolation pipe 20. The annular limiting plate 64 is embedded in the top of the fixed platform 632, which can further enhance the connection strength between the reinforcing sleeve 60 and the fixed platform 632, prevent the top of the reinforcing sleeve 60 from tilting or shifting, and ensure the long-term stability of the entire reinforcing structure.

[0045] In this embodiment, the inner wall of the reinforcing sleeve 60 is provided with a plurality of guide strips 66 extending axially at intervals, and the outer wall of the isolation tube 20 is provided with a matching guide groove 23 corresponding to the guide strips 66, and the guide strips 66 are slidably embedded in the guide groove 23. The elastic buffer layer is an annular rubber pad 62, which is sleeved on the outside of the isolation tube 20. The inner ring of the annular rubber pad 62 is tightly fitted to the outer wall of the isolation tube 20, and the outer ring of the annular rubber pad 62 is tightly fitted to the inner wall of the reinforcing sleeve 60. Multiple annular rubber pads 62 are arranged at intervals along the axial direction of the reinforcing sleeve 60. Both the inner and outer rings of the annular rubber pad 62 are provided with annular grooves, and metal reinforcing rings 621 are embedded in the annular grooves.

[0046] The guide strip 66 on the inner wall of the reinforcing sleeve 60 cooperates with the guide groove 23 on the outer wall of the isolation tube 20 to restrict the lateral movement of the isolation tube 20, ensuring that the isolation tube 20 can only move vertically and preventing the isolation tube 20 from tilting or deviating; the elastic buffer layer adopts annular rubber pads 62, whose elasticity can effectively absorb disturbances; multiple annular rubber pads 62 are arranged at intervals along the axial direction to achieve buffering within the entire length range and improve the anti-interference effect; the metal reinforcing rings 621 of the inner and outer rings of the annular rubber pads 62 can enhance the structural strength of the rubber pads, prevent the rubber pads from deforming under long-term pressure, extend the service life of the buffer layer, and ensure long-term anti-interference capability.

[0047] In this embodiment, the inner wall of the isolation tube 20 is provided with a plurality of guide rings 24 at intervals along the axial direction. The inner ring of the guide ring 24 is in clearance fit with the outer wall of the layering bar 30. The inner ring of the guide ring 24 is embedded with friction-reducing balls 25, which are in rolling contact with the outer wall of the layering bar 30.

[0048] The guide ring 24 restricts the lateral displacement of the stratification marker 30, ensuring that the stratification marker 30 always moves vertically. The anti-friction balls 25 in the inner ring of the guide ring 24 roll into contact with the outer wall of the stratification marker 30, converting sliding friction into rolling friction. This significantly reduces the resistance when the stratification marker 30 is displaced, ensuring that the stratification marker 30 can follow the target stratum in real time and synchronously, avoiding displacement data lag caused by friction, and improving the real-time performance and accuracy of monitoring data.

[0049] A cement grouting layer is filled between the reinforcing sleeve 60 and the wall of the monitoring hole 10.

[0050] 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.
