Description

Technical Field

[0001] The invention relates to the technical field of dynamic monitoring of slopes, and in particular to a system and method for dynamic monitoring of high slopes during construction. Background Art

[0002] The construction of mountain roads inevitably involves excavation of the mountains, which destroys the original geological conditions and forms road cutting slopes. Road cutting slope instability, landslides and other disasters are highly hidden.

[0003] The surface of the slope is an inclined plane with a gradient. Under the action of gravity, the entire slope has a tendency to slide from high to low. Generally speaking, there are two forces acting simultaneously on the rock and soil of the slope, namely, sliding force and anti-sliding force. The surface of the slope is soil, the interior is rock, and the landslide part is soil.

[0004] Existing slope monitoring is carried out through displacement detection, because displacement is a necessary condition for slope landslide. Existing displacement monitoring usually involves deploying displacement sensors at multiple points for in-situ monitoring. This monitoring method has high initial investment costs, and when multiple points on the slope are displaced simultaneously (such as landslides on the entire slope at the same time), multiple displacement sensors and the monitoring area will move synchronously, and the displacement cannot be effectively captured.

[0005] The present invention provides a high slope dynamic monitoring system and method during the construction process, which can greatly reduce and reduce the use of sensors, reduce the cost of early deployment, and can increase the sensitivity to displacement capture, and has the advantages of wide monitoring range, low cost and good effect. Summary of the invention

[0006] The purpose of the present invention is to provide a high slope dynamic monitoring system and method during construction, which can greatly reduce and reduce the use of sensors, reduce the cost of early deployment, and increase the sensitivity of displacement capture. It has the advantages of wide monitoring range, low cost and good effect.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dynamic monitoring system for high slopes during construction, comprising a monitoring box, the monitoring box is anchored by driving anchor rods into the rock layer inside the slope, the monitoring box is arranged at the middle position of the top of the slope in the monitoring area, a slide plate is arranged inside the monitoring box, the top of the slide plate is fixedly connected to a fixed pointer through a fixed shaft, the top of the slide plate is rotatably connected to a pulley through a fixed shaft, a traction rope is attached to the outside of the pulley, and both ends of the traction rope are led out downward and extend to both sides of the monitoring area;

[0008] Multiple entrapment plates are embedded on both sides of the monitoring area. The entrapment plates are laterally embedded on the inner side of the slope. A concave surface is provided on the upper direction of the entrapment plates. The concave surface is used to increase the contact area with the inside of the slope and increase the joint effect between the entrapment plates and the inside of the slope. A triangular head is fixedly connected to the bottom end of the entrapment plate. The triangular head facilitates entrapment. The connecting line of multiple entrapment plates on each side is inclined on the surface of the slope. The entrapment plates can move with the movement of the slope surface. The top of the entrapment plate is rotatably connected with a connecting ring. The entrapment plates distributed on both sides are symmetrically arranged. The two ends of the traction rope pass through the multiple connecting rings on both sides respectively.

[0009] The slope is monitored by obtaining the rotation or sliding of the pulley.

[0010] The inner side of the monitoring box is slidably connected to the slide plate, and a connection point is provided on the traction rope, and the connection point is provided in the lower direction of each connection ring. When the traction rope goes up, the connection point will be stuck in the connection ring;

[0011] When any of the entrapment plates and the connecting ring in the monitoring area moves downwards, it can drive the connection point and the traction rope there downwards, the upper side of the pulley will rotate in the downward direction of the traction rope, and the slide plate will move downwards at the same time;

[0012] When the earth-entering plates and connecting rings on both sides of the monitoring box move downward at the same time, the connecting points and traction ropes on both sides can be driven downward, and the slide plate will move downward to achieve monitoring.

[0013] The monitoring box in the present invention is anchored by driving an anchor rod into the rock layer inside the top of the slope, and will not move. After the stable state of the slope is broken, it will move downward. Under the above settings, the present invention can achieve effective monitoring of the slope monitoring area. This monitoring method has a wide monitoring range and low initial deployment cost. It avoids the problem that the existing displacement monitoring usually involves deploying displacement sensors at multiple points for in-situ monitoring. When the slope is simultaneously displaced at multiple points, multiple displacement sensors and the monitoring area will move synchronously, and the displacement cannot be effectively captured.

[0014] The monitoring method is: when any of the embedded plates and the connecting rings in the monitoring area are displaced downwards individually, the connection point and the traction rope on that side can be driven downwards, and the upper direction of the pulley will rotate toward the side where the traction rope is downwards, and the slide plate will move downwards at the same time. At this time, the pulley is a movable pulley, which should be able to meet the situation that the traction amount generated by the downward traction rope on one side is twice the downward displacement of the slide plate. The traction amount of the downward traction rope can be obtained by observing the rotation angle and radius of the pulley. When the traction amount of the downward traction rope on one side is not twice the downward displacement of the slide plate, it is necessary to consider the multi-point displacement on both sides of the monitoring box;

[0015] As a preferred high slope dynamic monitoring system during the construction process of the present invention, a limit rod is fixedly connected to the inner side of the monitoring box, the outer side of the limit rod is slidably connected to the inner side of the slide plate, and a second spring is provided on the outer side of the limit rod, and the two ends of the second spring are respectively fixedly connected to one end of the slide plate and the inner side of one end of the monitoring box.

[0016] The limit rod is used to increase the stability of the slide when it slides, and the second spring is used to play a role of reset;

[0017] As a preferred embodiment of the high slope dynamic monitoring system during the construction process of the present invention, scale lines are engraved on the pulley. When the pulley rotates, the position of the fixed pointer on the scale lines will change. The upper surface of the monitoring box is a glass panel, through which the position of the pulley and the position of the fixed pointer on the scale lines can be observed.

[0018] As a preferred high slope dynamic monitoring system during construction of the present invention, a potentiometer is fixedly connected to the bottom of the monitoring box, and the slide slides on the surface of the potentiometer. The sliding position of the slide can be obtained through the potentiometer. The potentiometer sends the sliding position of the slide after movement to an external controller, and the controller controls the alarm device to work to achieve a warning effect. The alarm device is not shown and can be installed in the monitoring room.

[0019] The high slope dynamic monitoring method during construction includes the following steps:

[0020] Step 1: When any of the embedded plates and the connecting rings in the monitoring area move downwards, the connecting point and the traction rope on that side can be driven downwards. The upper direction of the pulley will rotate toward the side where the traction rope is downwards, and the slide plate will move downwards at the same time. At this time, the pulley acts as a "moving pulley";

[0021] Step 2: When the earth-entering plates and connecting rings on both sides move downward at the same time, and the downward displacement on both sides of the slope is the same, the connecting points and traction ropes on both sides can be driven downward, the pulley does not rotate, and the slide plate will move downward to achieve monitoring;

[0022] Step 3: When the entrapment plates and connecting rings on both sides move downward at the same time and the downward displacement on both sides of the slope is inconsistent, the connection points and traction ropes on both sides can be driven downward, the pulley rotates and the slide plate moves downward to achieve monitoring.

[0023] The high slope dynamic monitoring system during construction includes a monitoring box, which is anchored by driving anchor rods into the rock layer inside the slope. The monitoring box is arranged at the middle position of the top of the slope in the monitoring area. A slide plate is arranged inside the monitoring box. The top of the slide plate is fixedly connected to a fixed pointer through a fixed shaft. The top of the slide plate is rotatably connected to a pulley through a fixed shaft. A traction rope is attached to the outside of the pulley. Both ends of the traction rope are led downward and extend to both sides of the monitoring area.

[0024] Multiple earth-entering plates are embedded on both sides of the monitoring area. The earth-entering plates are transversely embedded in the inner side of the slope. A concave surface is set in the upper direction of the earth-entering plates. The bottom end of the earth-entering plates is fixedly connected with a triangular head. The connecting line of multiple earth-entering plates on each side is inclined on the surface of the slope. The earth-entering plates can move with the movement of the slope surface. The top of the earth-entering plates is rotatably connected with a connecting ring. The earth-entering plates distributed on both sides are symmetrically arranged. The two ends of the traction rope pass through the multiple connecting rings on both sides respectively.

[0025] The inner side of the monitoring box is fixedly connected to the slide plate, and a plurality of connection points are arranged on the traction rope, and the plurality of connection points are arranged in the lower direction of each connection ring. When the traction rope goes up, the connection points can pass through the inner side of the connection ring;

[0026] When any earth-entering plate and connecting ring in the monitoring area are displaced downward separately, the connection point and the traction rope at that location can be driven downward, and the upper side of the pulley will rotate toward the downward side of the traction rope, while the traction rope on the other side goes upward for distance compensation. When the earth-entering plates and connecting rings on both sides of the monitoring box are displaced downward at the same time, the traction rope breaker in the monitoring box will be disconnected due to excessive tension, thereby realizing monitoring. The breaker is a prior art and will not be elaborated on here. It can automatically disconnect when the tension is overloaded. In the present invention, the traction rope will not exceed the load of the breaker when it is pulled unilaterally.

[0027] The present invention also provides a similar monitoring method. Under the above setting, in the present invention, when a landslide occurs at one position, the earth-entering plate at that position will move downward, and the connecting ring at the top of the earth-entering plate will be stuck on the connecting point, driving the traction rope on that side to move downward. At this time, the traction rope on the other side of the monitoring box will drag the card block in the connecting point on that side, so that the card block enters the slide groove to hide the card block. At this time, the traction rope on the other side can drive the connection point to slide over the inner side of the connecting ring. At this time, the pulley is a "fixed pulley" and the pulley will rotate. The potentiometer can send the position of the slider after moving to an external controller. The controller controls the alarm device to work to realize the warning effect. When the earth-entering plates and connecting rings on both sides of the monitoring box move downward at the same time, the breaker of the traction rope in the monitoring box will be disconnected due to excessive tension. The disconnection of the breaker will also send information to the external controller. The controller controls the alarm device to work to realize the warning effect and realize monitoring. It can effectively avoid the problem of insufficient sensitivity caused by the existing in-situ monitoring during synchronous displacement.

[0028] As a preferred embodiment of the high slope dynamic monitoring system during the construction process of the present invention, scale lines are engraved on the pulley. When the pulley rotates, the position of the fixed pointer on the scale lines will change. The upper surface of the monitoring box is a glass panel, through which the position of the pulley and the position of the fixed pointer on the scale lines can be observed.

[0029] As a preferred high slope dynamic monitoring system during the construction process of the present invention, a ring-shaped potentiometer is fixedly connected to the outer side of the fixed shaft, and a slider is fixedly connected to the inner side of the pulley. The slider slides on the potentiometer. The potentiometer can send the position of the slider after movement to an external controller, and the controller controls the alarm device to achieve a warning effect.

[0030] As a preferred embodiment of the high slope dynamic monitoring system during the construction process of the present invention, the connection point interrupts and connects the traction rope, the front end of the connection point has a conical surface to guide the internal perforation of the connection ring, and the outer edge of the connection point is slidably connected with a block. When the traction rope is pulled upward, the block can slide into the slide groove inside the connection point. At this time, the connection point can pass through the inner side of the connection ring;

[0031] A first spring is arranged inside the slide groove, and two ends of the first spring are respectively fixedly connected to the inner side of the slide groove and one end of the block. After the traction rope enters the connection point, it slides over the roller to change direction and is fixedly connected to one end of the block. The tail end of the connection point is fixedly connected to the traction rope again to achieve connection.

[0032] A convex ring is fixedly connected to the lower side of the connecting ring, and a groove is opened on the inner side of the clamping block. When the connecting ring moves downward, the convex ring on the connecting ring enters the groove in the clamping block. At this time, the clamping block cannot enter the slide groove, and the connecting ring drives the connecting point to move downward.

[0033] The high slope dynamic monitoring method during construction includes the following steps:

[0034] Step 1: When any of the embedded plates and the connecting rings in the monitoring area move downwards, the connection point and the traction rope at that location can be driven downwards. The upper side of the pulley will rotate toward the side where the traction rope is downwards, and the traction rope on the other side will move upwards to compensate for the distance. At this time, the pulley is a "fixed pulley";

[0035] Step 2: When the earth-entering plates and connecting rings on both sides of the monitoring box move downward at the same time, the breaker of the traction rope in the monitoring box will be disconnected due to excessive tension, thus achieving monitoring.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The high slope dynamic monitoring system during the construction process of the present invention can realize effective monitoring of the slope monitoring area. This monitoring method has a wide monitoring range and low initial deployment cost. It avoids the problem that the existing displacement monitoring usually deploys displacement sensors at multiple points for in-situ monitoring. When the slope is faced with simultaneous displacement at multiple points, it will cause multiple displacement sensors and the monitoring area to move synchronously, and the displacement cannot be effectively captured.

[0038] 2. The dynamic monitoring system for high slopes during the construction process uses the following monitoring method: when any of the embedded plates and the connecting rings in the monitoring area are displaced downward individually, the connecting point and the traction rope on that side can be driven downward, and the upper direction of the pulley will rotate toward the side where the traction rope is downward, and the slide plate will move downward at the same time. At this time, the pulley is a movable pulley, which should be able to meet the situation where the traction amount generated by the downward traction rope on one side is twice the downward displacement of the slide plate. The traction amount of the downward traction rope can be obtained by observing the rotation angle and radius of the pulley. When the traction amount of the downward traction rope on one side is not twice the downward displacement of the slide plate, multi-point displacement on both sides of the monitoring box needs to be considered.

[0039] 3. A dynamic monitoring system for high slopes during the construction process. In the present invention, the connection lines of multiple earth-entering plates on each side are arranged obliquely on the surface of the slope, and can be extended until close to the foot of the slope. The monitoring area includes sub-areas, namely S1, S2, S3, S4 and S5. The monitoring box is arranged on the top of the slope at the top of S3, and the traction rope and earth-entering plate on the left side of the monitoring box are arranged on S1 and S2. When the earth-entering plate on S2 moves downward, the straight-line distance between the earth-entering plate on S2 and the earth-entering plate on S1 decreases, that is, the traction rope between the earth-entering plate on S2 and the earth-entering plate on S1 will become loose. After the alarm, the traction rope can be observed by the drone to see where the traction rope becomes loose, so as to identify where the displacement occurs and take targeted prevention measures at that place.

[0040] 4. The dynamic monitoring system for high slopes during the construction process. In the present invention, when a landslide occurs at one position, the earth-entering plate at that position will move downward, and the connecting ring at the top of the earth-entering plate will be stuck on the connecting point, driving the traction rope on that side to move downward. At this time, the traction rope on the other side of the monitoring box will drag the block in the connecting point on that side, so that the block enters the slide groove to hide the block. At this time, the traction rope on the other side can drive the connecting point to slide over the inner side of the connecting ring. At this time, the pulley is a "fixed pulley" and the pulley will rotate. The potentiometer can send the position of the slider after moving to an external controller. The controller controls the alarm device to work to realize the warning effect. When the earth-entering plates and connecting rings on both sides of the monitoring box move downward at the same time, the breaker of the traction rope in the monitoring box will be disconnected due to excessive tension. The disconnection of the breaker will also send information to the external controller. The controller controls the alarm device to work to realize the warning effect and realize monitoring. It can effectively avoid the problem of insufficient sensitivity caused by the existing in-situ monitoring during synchronous displacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Example 1, please refer to Figure 1-Figure 7 The present invention provides a technical solution: a dynamic monitoring system for high slopes during construction, comprising a monitoring box 4, which is anchored by driving an anchor rod 24 into a rock layer inside a slope 1, and is characterized in that: the monitoring box 4 is arranged at the middle position of a slope top 3 in a monitoring area, a slide plate 23 is slidably connected to the inner side of the monitoring box 4, a fixed pointer 20 is fixedly connected to the top of the slide plate 23 through a fixed shaft 26, a pulley 19 is rotatably connected to the top of the slide plate 23 through a fixed shaft 26, a traction rope 7 is attached to the outer side of the pulley 19, and both ends of the traction rope 7 are led out downward and extend to both sides of the monitoring area;

[0057] Multiple entrapment plates 10 are embedded on both sides of the monitoring area. The entrapment plates 10 are transversely embedded in the inner side of the slope 1. A concave surface 101 is provided in the upper direction of the entrapment plates 10. A triangular head 102 is fixedly connected to the bottom end of the entrapment plates 10. The connecting line of multiple entrapment plates 10 on each side is inclinedly arranged on the surface of the slope 1. The entrapment plates 10 can move with the movement of the surface of the slope 1. The top of the entrapment plates 10 is rotatably connected with a connecting ring 9. The entrapment plates 10 distributed on both sides are symmetrically arranged. The two ends of the traction rope 7 pass through the multiple connecting rings 9 on both sides respectively.

[0058] The traction rope 7 is provided with a connection point 11, which is arranged in the lower direction of each connection ring 9. When the traction rope 7 goes up, the connection point 11 will be stuck in the connection ring 9;

[0059] When any entrapment plate 10 and connection ring 9 in the monitoring area move downward independently, the connection point 11 and traction rope 7 there can be driven downward, the upper side of the pulley 19 will rotate in the downward direction of the traction rope 7, and the slide plate 23 will move downward at the same time;

[0060] When the burying plates 10 and the connecting rings 9 on both sides of the monitoring box 4 move downward at the same time, the connecting points 11 and the traction ropes 7 on both sides can be driven downward, and the slide plate 23 will move downward to achieve monitoring.

[0061] The monitoring box 4 in the present invention is anchored by driving the anchor rod 24 into the rock layer inside the top of the slope 3 at the top of the slope 1, and will not move. After the stable state of the slope 1 is broken, it will move downward. Under the above settings, the present invention can achieve effective monitoring of the monitoring area of ​​the slope 1. This monitoring method has a wide monitoring range and low initial deployment cost, avoiding the existing displacement monitoring method of usually deploying displacement sensors at multiple points for in-situ monitoring. When facing the simultaneous displacement of multiple points on the slope, it will cause multiple displacement sensors and the monitoring area to move synchronously, and the problem of being unable to effectively capture the displacement.

[0062] The monitoring method is: when any one of the earth-entering plates 10 and the connecting ring 9 in the monitoring area moves downward independently, the connecting point 11 and the traction rope 7 on that side can be driven downward, and the upper direction of the pulley 19 will rotate toward the side where the traction rope 7 is downward, and the slide plate 23 will move downward at the same time. At this time, the pulley 19 is a movable pulley, which should be able to meet the situation where the traction amount generated by the downward traction rope 7 on one side is twice the downward displacement of the slide plate 23. The traction amount of the downward traction rope 7 can be obtained by observing the rotation angle of the pulley 19 and the radius of the pulley. When the downward traction amount of the traction rope 7 on one side is not twice the downward displacement of the slide plate 23, it is necessary to consider the multi-point displacement on both sides of the monitoring box 4.

[0063] In the present invention, the connecting line of the multiple entrapment plates 10 on each side is arranged obliquely on the surface of the slope 1, and can be extended to the slope foot 2, such as Figure 1 As shown, the monitoring area includes 5 sub-areas, namely S1, S2, S3, S4 and S5, and the monitoring box 4 is arranged on the top of the slope 3 at the top of S3, and the traction rope 7 and the earth-entering plate 10 on the left side of the monitoring box 4 are arranged on S1 and S2. When the earth-entering plate 10 on S2 moves downward, the straight-line distance between the earth-entering plate 10 on S2 and the earth-entering plate 10 on S1 decreases, that is, the traction rope 7 between the earth-entering plate 10 on S2 and the earth-entering plate 10 on S1 will become loose. After the alarm, the traction rope 7 is observed by the drone where the traction rope 7 becomes loose (no large-scale large displacement sliding occurs), and the displacement can be identified, and targeted prevention can be taken at that place; in the present invention, the number of earth-entering plates 10 on each sub-area can be increased, and the earth-entering plates 10 on each sub-area can be connected to further increase the monitoring accuracy;

[0064] Specifically, the inner side of the monitoring box 4 is fixedly connected to a limit rod 17, the outer side of the limit rod 17 is slidably connected to the inner side of the slide plate 23, and a second spring 22 is provided on the outer side of the limit rod 17. The two ends of the second spring 22 are respectively fixedly connected to one end of the slide plate 23 and the inner side of one end of the monitoring box 4.

[0065] The limit rod 17 is used to increase the stability of the slide plate 23 when it slides, and the second spring 22 is used to play a role of reset;

[0066] Specifically, the pulley 19 is engraved with scale lines 21. When the pulley 19 rotates, the position of the fixed pointer 20 on the scale lines 21 will change. The upper surface of the monitoring box 4 is a glass panel 5, through which the position of the pulley 19 and the position of the fixed pointer 20 on the scale lines 21 can be observed.

[0067] Specifically, a potentiometer 25 is fixedly connected to the bottom of the monitoring box 4, and the slide plate 23 slides on the surface of the potentiometer 25. The sliding position of the slide plate 23 can be obtained through the potentiometer 25. The potentiometer 25 sends the sliding position of the slide plate 23 after movement to the external controller 18, and the controller 18 controls the alarm device to work to achieve the warning effect. The alarm device is not shown and can be installed in the monitoring room.

[0068] This embodiment also discloses a method for dynamic monitoring of high slopes during construction, the steps of which are:

[0069] Step 1: When any burying plate 10 and connecting ring 9 in the monitoring area move downward separately, the connecting point 11 and traction rope 7 on that side can be driven downward, and the upper direction of the pulley 19 will rotate toward the side where the traction rope 7 moves downward, and the slide plate 23 will move downward at the same time. At this time, the pulley 19 plays the role of a "movable pulley";

[0070] Step 2: When the burying plates 10 and the connecting rings 9 on both sides move downward at the same time, and the downward displacement on both sides of the slope 1 is the same, the connecting points 11 and the traction rope 7 on both sides can be driven downward, the pulley 19 does not rotate, and the slide plate 23 moves downward to achieve monitoring;

[0071] Step 3: When the burying plates 10 and the connecting rings 9 on both sides move downward at the same time and the downward displacement on both sides of the slope 1 is inconsistent, the connecting points 11 and the traction rope 7 on both sides can be driven downward, the pulley 19 rotates and the slide plate 23 moves downward to achieve monitoring.

[0072] Among them, in the embodiment of the monitoring results, in the situation described in step three, the downward movement of the slide plate 23 will be higher than that described in step one.

[0073] Example 2: This example is an alternative to Example 1. Figure 1-Figure 3 and Figure 8-Figure 12The high slope dynamic monitoring system during construction includes a monitoring box 4, which is anchored by driving an anchor rod 24 into the rock layer inside the slope 1. The monitoring box 4 is arranged in the middle of the slope top 3 in the monitoring area. A slide plate 23 is fixedly connected to the inner side of the monitoring box 4, and a fixed pointer 20 is fixedly connected to the top of the slide plate 23 through a fixed shaft 26. The top of the slide plate 23 is rotatably connected to a pulley 19 through the fixed shaft 26. A traction rope 7 is attached to the outer side of the pulley 19, and both ends of the traction rope 7 are led out downward and extend to both sides of the monitoring area.

[0074] Multiple entrapment plates 10 are embedded on both sides of the monitoring area. The entrapment plates 10 are laterally embedded in the inner side of the slope 1. A concave surface 101 is provided in the upper direction of the entrapment plates 10. A triangular head 102 is fixedly connected to the bottom end of the entrapment plates 10. The connecting line of multiple entrapment plates 10 on each side is inclinedly arranged on the surface of the slope 1. The entrapment plates 10 can move with the movement of the surface of the slope 1. The top of the entrapment plates 10 is rotatably connected with a connecting ring 9. The entrapment plates 10 distributed on both sides are symmetrically arranged. The two ends of the traction rope 7 pass through the multiple connecting rings 9 on both sides respectively.

[0075] The traction rope 7 is provided with a plurality of connection points 11, and the plurality of connection points 11 are arranged in the lower direction of each connection ring 9. When the traction rope 7 goes up, the connection points 11 can pass through the inner side of the connection ring 9;

[0076] When any earth-entering plate 10 and connecting ring 9 in the monitoring area are displaced downward individually, the connection point 11 and the traction rope 7 there can be driven downward, and the upper side of the pulley 19 will rotate toward the downward side of the traction rope 7, and the traction rope 7 on the other side will go up for distance compensation. When the earth-entering plates 10 and connecting rings 9 on both sides of the monitoring box 4 are displaced downward at the same time, the breaker 6 of the traction rope 7 in the monitoring box 4 will be disconnected due to excessive tension, thereby realizing monitoring.

[0077] The present invention also provides a similar monitoring method. Under the above setting, in the present invention, when a landslide occurs at one position, the burying plate 10 at that position will move downward, and the connecting ring 9 at the top of the burying plate 10 will be stuck on the connecting point 11, driving the traction rope 7 on that side to move downward. At this time, the traction rope 7 on the other side of the monitoring box 4 will drag the block 12 in the connecting point 11 on that side, so that the block 12 enters the slide groove 14, and the block 12 is hidden. At this time, the traction rope 7 on the other side can drive the connecting point 11 to slide over the inner side of the connecting ring 9. At this time, the pulley 19 is a "fixed pulley". The pulley 19 will rotate, and the potentiometer 25 can send the position of the slider 8 after moving to the external controller 18. The controller 18 controls the alarm device to realize the warning effect. When the earth-entering plates 10 and the connecting rings 9 on both sides of the monitoring box 4 move downward at the same time, the breaker 6 of the traction rope 7 in the monitoring box 4 will be disconnected due to excessive tension. The disconnection of the breaker 6 will also send information to the external controller 18. The controller 18 controls the alarm device to realize the warning effect and realize monitoring. It can effectively avoid the problem of insufficient sensitivity caused by the existing in-situ monitoring during synchronous displacement.

[0078] Specifically, the pulley 19 is engraved with scale lines 21. When the pulley 19 rotates, the position of the fixed pointer 20 on the scale lines 21 will change. The upper surface of the monitoring box 4 is a glass panel 5, through which the position of the pulley 19 and the position of the fixed pointer 20 on the scale lines 21 can be observed.

[0079] Specifically, a ring-shaped potentiometer 25 is fixedly connected to the outer side of the fixed shaft 26, and a slider 8 is fixedly connected to the inner side of the pulley 19. The slider 8 slides on the potentiometer 25. The potentiometer 25 can send the position of the slider 8 after movement to the external controller 18. The controller 18 controls the alarm device to achieve a warning effect.

[0080] Specifically, the connection point 11 interrupts and connects the traction rope 7. The front end of the connection point 11 has a conical surface 13 that serves as a guide for the internal perforation of the connection ring 9. The outer edge of the connection point 11 is slidably connected with a block 12. When the traction rope 7 is pulled upward, the block 12 can slide into the slide groove 14 inside the connection point 11. At this time, the connection point 11 can pass through the inner side of the connection ring 9.

[0081] A first spring 16 is arranged inside the slide groove 14, and two ends of the first spring 16 are respectively fixedly connected to the inner side of the slide groove 14 and one end of the block 12. After the traction rope 7 enters the connection point 11, it slides over the roller 15 to change direction and is fixedly connected to one end of the block 12. The tail end of the connection point 11 is fixedly connected to the traction rope 7 again to achieve connection.

[0082] A convex ring 28 is fixedly connected to the lower side of the connecting ring 9, and a groove 27 is provided on the inner side of the block 12. When the connecting ring 9 moves downward, the convex ring 28 on the connecting ring 9 enters the groove 27 in the block 12. At this time, the block 12 cannot enter the slide groove 14, and the connecting ring 9 drives the connecting point 11 to move downward.

[0083] This embodiment also discloses a method for dynamic monitoring of high slopes during construction, the steps of which are:

[0084] Step 1: When any burying plate 10 and connecting ring 9 in the monitoring area move downwards alone, the connecting point 11 and traction rope 7 there can be driven downwards, and the upper side of the pulley 19 will rotate toward the downward side of the traction rope 7, and the traction rope 7 on the other side will move upwards to compensate for the distance. At this time, the pulley 19 is a "fixed pulley";

[0085] Step 2: When the earth-entering plates 10 and the connecting rings 9 on both sides of the monitoring box 4 move downward at the same time, the breaker 6 of the traction rope 7 in the monitoring box 4 will be disconnected due to excessive tension, thereby achieving monitoring.

[0086] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
