Description

Technical Field

[0001] The invention relates to the technical field of disaster monitoring, in particular to an underground cave disaster monitoring station. Background Art

[0002] Today, as underground space is increasingly developed and utilized, underground caverns are an important part of various engineering facilities, and their safety and stability are directly related to the safety of life and property of personnel and the efficiency of engineering operations. However, the geological environment in which underground caverns are located is complex and changeable, and is easily affected by various factors such as crustal movement, groundwater activity, and soil loosening, which leads to subtle changes in the geological state, which may in turn cause geological disasters such as cavern collapse and surface subsidence. Traditional geological monitoring methods, such as drilling sampling and analysis, and installation of large-scale monitoring instruments, are not only complex and costly to operate, but may also cause additional interference to underground caverns and the surrounding geological environment during implementation, and even induce disasters. Therefore, it is particularly important to develop a real-time, accurate, and less disturbing underground cavern disaster monitoring technology.

[0003] Most existing monitoring technologies rely on fixed-point observations and periodic inspections, which makes it difficult to achieve continuous and dynamic monitoring. In addition, the monitoring range is limited, making it difficult to fully cover the key areas around underground caverns. In addition, the data processing and analysis of traditional monitoring methods often rely on manual work, which is not only inefficient but also easily affected by subjective factors, resulting in a significant reduction in the accuracy and reliability of monitoring results. With the rapid development of information technology and sensor technology, how to use these advanced technologies to build an efficient and intelligent underground cavern disaster monitoring system has become an urgent problem to be solved. Summary of the invention

[0004] The present invention aims to provide an underground cavern disaster monitoring station, which realizes real-time monitoring and accurate early warning of changes in geological conditions around the underground cavern, provides strong technical support for the safe use of underground space, and has a good monitoring and protection effect on water and mud bursts.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: An underground cave disaster monitoring station, comprising: A monitoring well is opened on one side of the underground cavern, wherein a plurality of wall wells are arranged vertically on the inner wall of the monitoring well, the elevation of the wellhead of each wall well is higher than the elevation of the well bottom, a flexible tube is fixedly embedded in each wall well, and a movable column is movably arranged in the flexible tube; A manhole cover is provided at the wellhead of the monitoring well, and a vertical plate is movably arranged between the manhole cover and the bottom of the monitoring well, and a plurality of tension sensors corresponding to the number and position of each wall well are arranged on the vertical plate, and a cable is connected between each tension sensor and each movable column in a one-to-one correspondence; A machine room is provided at the mouth of the monitoring well, and a traction rope is connected to the side of the vertical plate away from each of the tension cables. The traction rope extends upward through the well cover and extends into the machine room. A computer is arranged in the machine room, and the computer is electrically connected to each of the tension sensors.

[0006] In some embodiments, the inner wall of the monitoring well is hardened.

[0007] In some embodiments, the manhole cover and the portion where the bottom of the monitoring well contacts the vertical plate are slopes, and the inclination of the slope surface is consistent with the inclination of the wall well.

[0008] In some embodiments, the flexible tube is made of polyethylene.

[0009] In some embodiments, a plurality of rollers are disposed on the side wall of the movable column, and a plurality of guide grooves corresponding to each of the rollers are disposed on the inner wall of the flexible tube.

[0010] In some embodiments, the traction rope is connected to the center of the vertical board, and a plurality of auxiliary ropes are connected to the vertical board, one end of each of the auxiliary ropes is connected to the edge of the vertical board, and the other end is centrally connected to the traction rope.

[0011] In some embodiments, a guide wheel is provided in the monitoring well, and the extension path of the traction rope is transformed from horizontal to vertical upward through the guide wheel.

[0012] In some embodiments, a rope twisting machine and a motor are provided in the machine room, the traction rope is connected to the rope twisting machine, the motor is used to drive the rope twisting machine to twist the traction rope, and the motor is controlled by the computer.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention realizes real-time perception of small geological deformations around underground caverns by setting up several inclined wall wells and embedded tough pipes and movable columns. When the geological state changes, these changes will be immediately transmitted to the tough pipes through the deformation of the wall wells, thereby affecting the movement state of the movable columns. The tension sensor can capture this change in real time, convert it into an electrical signal, and transmit it to the computer system for processing. This design not only improves the real-time monitoring, but also ensures the accuracy of the monitoring data, providing a reliable basis for disaster warning.

[0014] Through the layout of multiple wall wells, the present invention can cover different depths and different positions around the underground caverns, and realize comprehensive monitoring of the geological state. The computer system can accurately measure and record the tension value of each movable column when the traction rope is pulled each time. By comparing historical data, abnormal fluctuations in the tension value can be discovered in time. These fluctuations often indicate abnormal changes in the geological state. This comprehensive monitoring and data analysis capability greatly improves the accuracy and comprehensiveness of monitoring, provides strong support for the safety management of underground space, and has a good monitoring and protection effect on water and mud inrush.

[0021] like Figure 1-6 As shown, this embodiment provides an underground cavern disaster monitoring station, including a monitoring well 200 opened on one side of the underground cavern 100 and having the same depth as the underground cavern 100. The monitoring well 200 is opened on one side of the underground cavern 100 and has the same depth as the underground cavern 100, so that the monitoring range can cover the key areas around the underground cavern 100, such as Figure 2As shown, it is best to evenly arrange multiple monitoring wells 200 around the underground cavern 100 to achieve more comprehensive monitoring. A plurality of wall wells 1 are vertically arranged on the inner wall of the monitoring well 200 close to the underground cavern 100. The wall wells 1 are parallel to each other and equidistant, and each wall well 1 is inclined so that the elevation of the wellhead of each wall well 1 is higher than the elevation of the well bottom. A flexible tube 2 is fixedly embedded in each wall well 1, and a movable column 3 is movably arranged in the flexible tube 2. When the movable column 3 is not subjected to external force, it will automatically slide to the bottom of the wall well 1 due to the inclined design of the wall well 1. A well cover 12 is provided at the wellhead of the monitoring well 200 to protect the equipment in the well from external interference. A vertical plate 8 is movably arranged between the well cover 12 and the bottom of the monitoring well 200. A plurality of tension sensors 7 corresponding to the number and position of each wall well 1 are arranged on the vertical plate 8. A cable 6 is connected one-to-one between each tension sensor 7 and each movable column 3 to transmit a tension signal. It also includes a machine room 300 covering the wellhead of the monitoring well 200. A traction rope 9 is connected to the side of the vertical plate 8 away from each tension cable 6. The traction rope 9 extends upward in the monitoring well 200 and passes through the well cover 12 and extends into the machine room 300. A computer 15 is installed in the machine room 300, and the computer 15 is electrically connected to each tension sensor 7.

[0022] When geological status monitoring is required, the monitoring personnel will pull the traction rope 9 regularly or as needed. The traction rope 9 extends upward in the monitoring well 200, passes through the manhole cover 12 and then extends into the machine room 300. Therefore, the monitoring personnel only need to enter the machine room 300 to pull the traction rope 9. Pulling the traction rope 9 will drive the vertical plate 8 to move away from each wall well 1, and then apply tension to each movable column 3 through the cable 6. Under the action of the tension, the movable column 3 will try to move upward in the tough pipe 2. If the geological status is stable, the movable column 3 will be able to move smoothly, and the tension sensor 7 will record a relatively stable tension value. If the geological status around the underground cavern 100 changes (such as slight movement of the earth's crust, loose soil, etc.), these changes will first affect the shape of the wall well 1, and then change the shape of the tough pipe 2, so that the movable column 3 moves. When the movable column 3 is blocked, the tension sensor 7 will record an abnormal tension value, which will be significantly higher or lower than the normal value. The tension sensor 7 will transmit the tension value monitored in real time to the computer 15 in the machine room 300 through an electrical signal. The computer 15 processes and stores these data and generates a historical data curve for subsequent analysis. By comparing the current tension value with the historical data, the computer 15 can identify any abnormal changes, which may indicate the instability of the geological state or potential signs of disasters. Once the computer 15 detects abnormal fluctuations in the tension value, it will immediately trigger the disaster warning mechanism. The monitoring personnel can take necessary measures in a timely manner according to the warning information, such as conducting on-site inspections, increasing the monitoring frequency or initiating emergency plans, etc., to ensure the safety of the underground cavern 100.

[0023] By setting up several inclined wall wells 1 and the tough tubes 2 and movable columns 3 embedded inside, the present invention can sense the slight deformation of the geology around the underground cavern 100 in real time. When the geological state changes, the deformation of the wall well 1 will be immediately transmitted to the tough tube 2, thereby affecting the movement state of the movable column 3. This change is captured in real time by the tension sensor 7 and converted into an electrical signal, realizing real-time monitoring of geological dynamics. Moreover, the combination of the tension sensor 7 and the computer 15 system enables the present invention to accurately measure and record the tension value of each movable column 3 each time the traction rope 9 is pulled. By comparing historical data, abnormal fluctuations in the tension value can be discovered in time. These fluctuations often indicate abnormal changes in the geological state, thereby providing disaster prevention and control measures. The present invention provides a reliable basis for warning, and compared with the traditional method of drilling sampling or installing large-scale monitoring equipment, the present invention adopts an embedded design, which has minimal interference with the underground cavern 100 and the surrounding geological environment, avoiding the risk of geological disasters that may be caused by the monitoring activities themselves, and the monitoring system mainly relies on the data processing of the tension sensor 7 and the computer 15, reducing the need for manual on-site inspections, reducing maintenance costs and work intensity. At the same time, the setting of the machine room 300 also provides good conditions for the protection of equipment and the safe storage of data. In addition, through the layout of multiple wall wells 1, the present invention can realize comprehensive monitoring of the geological conditions at different depths and different positions around the underground cavern 100, thereby improving the accuracy and comprehensiveness of monitoring.

[0024] In summary, the underground cavern disaster monitoring station of the present invention realizes real-time monitoring and accurate early warning of changes in geological conditions around the underground cavern 100 through the coordinated work of components such as the inclined wall well 1, movable column 3, tough tube 2, tension sensor 7 and computer 15. This innovative design not only improves the monitoring efficiency, but also ensures the accuracy and reliability of the monitoring data, and provides strong technical support for the safe use of underground space, especially for the monitoring and protection of water and mud bursts.

[0025] Preferably, the inner wall of the monitoring well 200 can be hardened, specifically by spraying or building the inner wall with high-strength, corrosion-resistant materials to form a hard protective layer. The hardening treatment not only enhances the structural strength of the inner wall of the monitoring well 200, enabling it to better resist damage such as extrusion and erosion that may be caused by the complex underground geological environment, but also significantly improves the smoothness of the inner wall, reducing the problem of movement obstruction of the active column 3 or measurement error of the tension sensor 7 caused by the rough inner wall.

[0026] Through hardening treatment, the load-bearing capacity and deformation resistance of the inner wall of the monitoring well 200 are greatly improved. Even when the geological conditions around the underground cavern 100 are complex and the crustal activities are frequent, the integrity and stability of the monitoring well 200 structure can be ensured, thereby providing reliable support for the entire monitoring system.

[0027] In addition, the hardening treatment of the inner wall makes its surface smoother, reducing the friction resistance of the movable column 3 when moving in the tough tube 2, ensuring that the tension sensor 7 can accurately capture the changes in the movement state of the movable column 3 caused by geological changes, thereby improving the accuracy and reliability of the monitoring data.

[0028] Moreover, the hardened layer acts as a barrier, effectively isolating the direct contact between the corrosive substances in the groundwater and soil and the inner wall of the monitoring well 200, slowing down the corrosion rate of the inner wall, extending the service life of the entire monitoring station, and reducing the long-term operating costs.

[0029] In addition, the hardened inner wall of the monitoring well 200 can better adapt to the monitoring needs under different geological conditions, and can maintain stable monitoring performance whether in soft soil, rock or mixed strata, thereby improving the versatility and practicality of the monitoring station.

[0030] In some embodiments, Figure 1 As shown, the parts where the manhole cover 12 and the bottom of the monitoring well 200 contact the vertical plate 8 are all slopes, and the inclination of the slope surface is consistent with the inclination of the wall well 1. Such a design ensures that the vertical plate 8 can always maintain good contact with the manhole cover 12 and the bottom of the monitoring well 200 during the up and down movement, and no additional friction resistance will be generated due to the unevenness of the contact surface or cause measurement errors of the tension sensor 7.

[0031] Specifically, the slope design allows a continuous and smooth transition to be formed between the contact surface of the vertical plate 8 and the manhole cover 12 and the bottom of the monitoring well 200 when the vertical plate 8 moves, thereby avoiding the friction resistance caused by the uneven contact surface, thereby ensuring that the tension sensor 7 can accurately capture the changes in the movement state of the movable column 3 caused by geological changes, thereby improving the monitoring sensitivity.

[0032] And because the inclination of the slope is consistent with the inclination of the wall well 1, the vertical plate 8 can always maintain the same tension direction as the movable column 3 in the wall well 1 during movement, avoiding the measurement error of the tension sensor 7 caused by angle deviation, and further improving the accuracy and reliability of the monitoring data.

[0033] Preferably, the tough tube 2 can be made of polyethylene, which has excellent corrosion resistance, wear resistance, flexibility and light weight. Polyethylene is a widely used plastic material, and its application in underground cave disaster monitoring stations can bring significant technical effects.

[0034] Specifically, the polyethylene material has excellent corrosion resistance and can resist erosion by various corrosive substances in groundwater and soil. In a complex geological environment such as the underground cavern 100, the polyethylene tough tube 2 can maintain stable performance for a long time and is not easily broken or deformed due to corrosion, thereby extending the service life of the entire monitoring station. The polyethylene material has good flexibility and can adapt to the deformation of the wall well 1 caused by geological changes to a certain extent. When the geological state changes, the polyethylene tough tube 2 can bend with the deformation of the wall well 1, but will not break, ensuring that the movable column 3 can move smoothly therein. This flexibility improves the sensitivity and accuracy of the monitoring system, so that even tiny geological deformations can be captured in time. And the polyethylene material has excellent wear resistance, which can resist the friction and wear generated when the movable column 3 moves in the tough tube 2. This wear resistance ensures that the tough tube 2 can maintain a smooth inner wall during long-term use, reduces the resistance to the movement of the movable column 3, and improves the accuracy and reliability of the monitoring data.

[0035] In some embodiments, Figure 3 and Figure 4 As shown, a plurality of rollers 4 are provided on the side wall of the movable column 3, and a plurality of guide grooves 5 corresponding to the rollers 4 are provided on the inner wall of the flexible tube 2. This design cleverly combines the mechanical principles of the rollers 4 and the guide grooves 5, providing a smoother and more stable guiding effect for the movement of the movable column 3 in the flexible tube 2.

[0036] Specifically, the setting of the roller 4 converts the sliding friction between the movable column 3 and the inner wall of the tough tube 2 into rolling friction, thereby significantly reducing the friction resistance during the movement. This change makes it easier for the movable column 3 to move in the tough tube 2, reduces the energy loss caused by friction, and improves the sensitivity of the monitoring system. Especially when there is a slight change in the geological state, this low-friction design can ensure that the movable column 3 responds in time, so that the tension sensor 7 can capture more accurate data. Moreover, the cooperation between the guide groove 5 and the roller 4 provides a stable guiding and limiting effect for the movable column 3. In the case that the tough tube 2 may undergo a slight deformation due to geological changes, the guide groove 5 can ensure that the movable column 3 moves along the predetermined path, avoiding measurement errors caused by path deviation. This stability is crucial to maintaining the accuracy and reliability of monitoring data. In addition, the design of the roller 4 and the guide groove 5 reduces the direct contact between the movable column 3 and the inner wall of the tough tube 2, thereby reducing the wear caused by friction. This design not only extends the service life of the movable column 3 and the tough tube 2, but also reduces the interference that debris generated by wear may cause to the monitoring system.

[0037] In some embodiments, Figure 1 and Figure 5As shown, the traction rope 9 is connected to the center of the vertical plate 8, and a plurality of auxiliary ropes 10 are connected to the vertical plate 8, one end of each auxiliary rope 10 is connected to the edge of the vertical plate 8, and the other end is centrally connected to the traction rope 9. Such a design not only enhances the stability of the vertical plate 8 during the pulling process, but also ensures the uniform distribution of the tension on the vertical plate 8, thereby improving the accuracy and reliability of monitoring. By connecting the traction rope 9 to the center of the vertical plate 8 and adding a plurality of auxiliary ropes 10 to connect the edge of the vertical plate 8 with the traction rope 9, a stable mechanical structure is formed. When the monitoring personnel pull the traction rope 9, this design can effectively prevent the vertical plate 8 from tilting or shaking due to uneven force, and ensure the stability of the vertical plate 8 during the up and down movement. This stability is crucial to maintaining the accurate measurement of the tension sensor 7, and avoids the measurement error caused by the shaking of the vertical plate 8. The setting of the auxiliary rope 10 makes the tension evenly distributed on the vertical plate 8. When the traction rope 9 is pulled, the tension is transmitted to each edge of the vertical plate 8 through the auxiliary rope 10, avoiding excessive local stress on the vertical plate 8 due to concentrated tension. This evenly distributed tension ensures that each tension sensor 7 can capture similar tension changes, improving the consistency and accuracy of the monitoring data. The connection of so many auxiliary ropes 10 enhances the connection strength between the vertical plate 8 and the traction rope 9. In a complex geological environment such as an underground cavern 100, this enhanced structural strength can ensure that the monitoring system maintains stability and reliability during long-term operation, reducing monitoring errors caused by loose or damaged structures.

[0038] In some embodiments, Figure 1 and Figure 5As shown, a guide wheel 11 is provided in the monitoring well 200, and the extension path of the traction rope 9 is transformed from horizontal to vertical upward through the guide wheel 11. The setting of the guide wheel 11 allows the extension path of the traction rope 9 to be smoothly transformed from horizontal to vertical upward. This transformation avoids unnecessary bending or folding of the traction rope 9 in the monitoring well 200, and reduces the friction resistance and wear caused by bending. The optimized traction rope 9 has a smoother direction, which makes it easier for monitoring personnel to pull the traction rope 9, improving the convenience of operation. The traction rope 9 changes direction through the guide wheel 11, avoiding direct friction contact with the inner wall or bottom of the monitoring well 200. This design significantly reduces the wear of the traction rope 9 during long-term use and extends its service life. At the same time, reducing friction also reduces the heat and noise generated by friction, and improves the stability and quietness of the entire monitoring system. And the guide wheel 11 ensures that the traction rope 9 can always maintain a stable vertical direction during the pulling process. This stability is crucial to maintaining the smooth movement of the vertical plate 8, and avoids the shaking or tilting of the vertical plate 8 caused by the deviation of the direction of the traction rope 9. The stable movement of the vertical plate 8 is the basis for accurate measurement of the tension sensor 7. Therefore, the design of the guide wheel 11 improves the accuracy and reliability of the monitoring data.

[0039] In some embodiments, Figure 6 As shown, a rope-twisting machine 13 and a motor 14 are provided in the machine room 300, and the traction rope 9 is connected to the rope-twisting machine 13. The motor 14 is used to drive the rope-twisting machine 13 to retract the traction rope 9. The motor 14 is controlled by a computer 15 so as to realize the automatic retraction and release of the traction rope 9 and the precise control of the tension. The design of the rope-twisting machine 13 driven by the motor 14 to retract the traction rope 9 realizes the automation of the monitoring process, reduces the need for manual operation and potential human errors. The monitoring personnel only need to set the corresponding parameters on the computer 15, and the motor 14 can automatically retract and release the traction rope 9 according to the preset program, which greatly improves the monitoring efficiency. This precise control enables the monitoring system to capture the changes in geological conditions more sensitively, and improves the accuracy and reliability of monitoring. In addition, the automatic retraction and release of the traction rope 9 also reduces the equipment damage or monitoring errors that may be caused by improper manual operation, reduces the maintenance cost and work intensity, and improves the stability and durability of the entire monitoring system.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
