Description

Technical Field

[0001] This invention belongs to the field of slope reinforcement technology, specifically relating to a slope reinforcement structure with landslide monitoring and early warning functions. Background Technology

[0002] Slope engineering is widely used in transportation, water conservancy, mining, and urban construction, and its stability directly affects the safety and long-term operation of the project. Under the influence of natural factors (such as rainfall, weathering, and earthquakes) and human activities (such as excavation and blasting), slope soil and rock masses are highly susceptible to deformation, creep, and even instability and landslides, which can cause significant casualties and property damage in severe cases. Therefore, effective slope reinforcement and long-term stability monitoring have always been important issues in the field of geotechnical engineering.

[0003] Currently, slope reinforcement mainly employs anchor (cable) support technology. This involves driving anchors into the slope and applying prestress to improve the overall stability of the slope. However, these traditional anchor structures have significant functional limitations—their primary function is passive support, and they lack the ability to monitor and provide feedback on slope deformation in real time.

[0004] Therefore, there is an urgent need to develop a slope reinforcement structure that integrates reinforcement and monitoring and early warning functions to achieve real-time perception and proactive early warning of slope deformation, and to provide reliable protection for the safe operation of slope engineering. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides a slope reinforcement structure with landslide monitoring and early warning functions, and specifically discloses the following technical solutions: A slope reinforcement structure with landslide monitoring and early warning function includes a slope with several reinforcing anchors anchored on it. The reinforcing anchors are arranged in a grid pattern. A monitoring mechanism is connected between each pair of adjacent reinforcing anchors by a reinforcing steel wire rope for monitoring the distance between the two reinforcing anchors. The monitoring mechanism includes a cylindrical shell. A sealing end plate is fixedly connected to one end of the cylindrical shell, and an open end plate is fixedly connected to the other end. A push plate is slidably installed inside the cylindrical shell. One end of one of the reinforcing steel wire ropes passes through a through hole in the center of the open end plate and is fixedly connected to one end of the push plate. A first spring is fixedly connected between the push plate and the open end plate. One end of the other reinforcing steel wire rope is fixedly connected to the outer end of the sealing end plate. An early warning mechanism is fixedly connected to the inner end of the sealing end plate. A push-button switch is fixedly installed on the surface of the early warning mechanism near the push plate for controlling the opening and closing of the early warning mechanism.

[0006] Furthermore, the early warning mechanism includes an alarm and a wireless signal transmitting device.

[0007] Furthermore, the reinforced anchor bolt includes an anchor bolt sleeve, a support column is slidably installed at the bottom inner end of the anchor bolt sleeve, a second spring is fixedly connected between the bottom end of the support column and the bottom end of the anchor bolt sleeve, a plurality of strip-shaped mounting holes are evenly opened circumferentially at the bottom side wall of the anchor bolt sleeve, an anchoring claw is installed inside each strip-shaped mounting hole, the bottom end of the anchoring claw is hinged to the bottom wall of the strip-shaped mounting hole, a connecting rod is hinged to the upper inner side of the anchoring claw, the other end of the connecting rod is hinged to the side wall of the support column, and a push rod is threadedly connected to the upper end of the reinforced anchor bolt, the bottom end of the push rod is used to push the support column to slide downward.

[0008] Furthermore, a strip-shaped groove is provided on the side of the support column corresponding to the position of each connecting rod, and the end of the connecting rod away from the anchoring claw is hinged in the strip-shaped groove.

[0009] Furthermore, the top rod includes a threaded rod portion at the upper end and a smooth rod portion fixedly connected to the bottom end of the threaded rod portion. The diameter of the smooth rod portion is smaller than the minimum diameter of the threaded rod portion. The upper inner end of the anchor bolt sleeve is provided with an internal thread. The threaded rod portion is threadedly connected to the upper inner end of the anchor bolt sleeve. The top end of the threaded rod portion extends out of the anchor bolt sleeve and is fixedly connected to a turning head.

[0010] Furthermore, a first grouting channel is provided inside the top rod, and a second grouting channel is provided inside the support column. A grouting hole communicating with the top end of the first grouting channel is provided on the top side of the top rod, and a plurality of grout outlet holes communicating with the bottom end of the second grouting channel are provided on the bottom side of the support column. After the bottom surface of the top rod is in contact with the top surface of the support column, the first grouting channel and the second grouting channel are connected to form a complete grouting channel.

[0011] Furthermore, a support cylinder is fixedly connected to the bottom of the inner side of the anchor bolt sleeve. The outer wall of the support cylinder is in close contact with the inner wall of the anchor bolt sleeve. A receiving hole with an inner diameter that gradually increases from bottom to top is opened in the center of the support cylinder for receiving the second spring. The top of the support cylinder is used to support and limit the support column.

[0014] Furthermore, four connecting lugs are fixedly connected to the top of the side wall of the anchor bolt jacket. The four connecting lugs are evenly distributed around the circumference and are used to connect the corresponding reinforcing steel wire ropes.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention not only includes reinforcing anchors to strengthen slopes, but also uses reinforcing steel wire ropes and monitoring mechanisms connected between the anchors to monitor slope deformation in real time. When slope deformation causes the distance between two reinforcing anchors to decrease, the tension of the reinforcing steel wire rope decreases, causing the push plate to push the push-type switch and trigger the early warning mechanism to provide an early warning, thus providing a reliable guarantee for the safe operation of slope engineering.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Figure 1-5 A slope reinforcement structure with landslide monitoring and early warning function includes a slope 1, on which several reinforcing anchors 2 are anchored. The reinforcing anchors 2 are distributed in a grid pattern. Each pair of adjacent reinforcing anchors 2 is connected to a monitoring mechanism 4 by a reinforcing steel wire rope 3 for monitoring the distance between the two reinforcing anchors 2. The monitoring mechanism 4 includes a cylindrical shell 41, one end of which is fixedly connected to a sealing end plate 42, and the other end is fixedly connected to an open end plate 43. The interior of the cylindrical shell 41 is slidably installed. There is a push plate 44. One end of a reinforcing steel wire rope 3 passes through a through hole in the center of the perforated end plate 43 and is fixedly connected to one end of the push plate 44. A first spring 45 is fixedly connected between the push plate 44 and the perforated end plate 43. One end of the other reinforcing steel wire rope 3 is fixedly connected to the outer end of the sealing end plate 42. An early warning mechanism 46 is fixedly connected to the inner end of the sealing end plate 42. A push-button switch 47 is fixedly installed on the surface of the early warning mechanism 46 near the push plate 44. The push-button switch 47 is used to control the opening and closing of the early warning mechanism 46. The reinforcing steel wire rope 3 between the two reinforcing anchor rods 2 is normally in a taut state. When the slope 1 experiences active or localized deformation, the distance between the corresponding reinforcing anchor rods 2 will decrease, resulting in a decrease in the tension of the reinforcing steel wire rope 3. This causes the first spring 45 to push the push plate 44 against the push-button switch 47, thereby causing the early warning mechanism 46 to issue an early warning.

[0024] In this embodiment, the early warning mechanism 46 includes an alarm and a wireless signal transmitter. When the early warning mechanism 46 is triggered, the alarm will sound an alarm to provide on-site reminders, and at the same time, the wireless signal transmitter will send early warning information to a remote mobile phone or computer to promptly remind the engineering management personnel.

[0025] In this embodiment, the reinforced anchor bolt 2 includes an anchor bolt sleeve 21. A support column 22 is slidably installed at the bottom of the inner end of the anchor bolt sleeve 21. A second spring 23 is fixedly connected between the bottom end of the support column 22 and the bottom end of the anchor bolt sleeve 21. Several strip-shaped mounting holes are evenly opened circumferentially at the bottom of the side wall of the anchor bolt sleeve 21. An anchoring claw 24 is installed inside each strip-shaped mounting hole. The bottom end of the anchoring claw 24 is hinged to the bottom wall of the strip-shaped mounting hole. A connecting rod 25 is hinged to the upper inner side of the anchoring claw 24. The other end of the connecting rod 25 is hinged to the side wall of the support column 22. A push rod 26 is threadedly connected to the upper end of the reinforced anchor bolt 2. The bottom end of the push rod 26 is used to push the support column 22 to slide downward. After the reinforcing anchor 2 is fully anchored into the slope 1, the top rod 26 is rotated, causing the top rod 26 to push the support column 22 downward. The angle of the connecting rod 25 changes and pushes the upper end of the anchoring claw 24 to gradually unfold outward, thereby inserting it into the surrounding soil and preventing the reinforcing anchor 2 from loosening.

[0026] In this embodiment, a strip-shaped groove 221 is provided on the side of the support column 22 corresponding to the position of each connecting rod 25. The end of the connecting rod 25 away from the anchor claw 24 is hinged in the strip-shaped groove 221, which can be used to accommodate the connecting rod 25.

[0027] In this embodiment, the top rod 26 includes a threaded rod portion 261 at the upper end and a smooth rod portion 262 fixedly connected to the bottom end of the threaded rod portion 261. The diameter of the smooth rod portion 262 is smaller than the minimum diameter of the threaded rod portion 261. The upper part of the inner end of the anchor rod sleeve 21 is provided with an internal thread. The threaded rod portion 261 is threadedly connected to the upper part of the inner end of the anchor rod sleeve 21. The top end of the threaded rod portion 261 extends out of the outside of the anchor rod sleeve 21 and is fixedly connected to a screw head 263 so that the top rod 26 can be rotated by the screw head 263.

[0028] In this embodiment, a first grouting channel 27 is provided inside the top rod 26, and a second grouting channel 28 is provided inside the support column 22. A grouting hole 29 communicating with the top end of the first grouting channel 27 is provided on the top side of the top rod 26, and several grout outlet holes 210 communicating with the bottom end of the second grouting channel 28 are provided on the bottom side of the support column 22. After the bottom surface of the top rod 26 and the top surface of the support column 22 are in contact, the first grouting channel 27 and the second grouting channel 28 are connected to form a complete grouting channel. After the anchor claw 24 on the reinforced anchor rod 2 is inserted into the surrounding soil, cement grout can be injected into the grouting hole 29. The cement grout is discharged sequentially through the first grouting channel 27, the second grouting channel 28, the grout outlet holes 210, and the strip-shaped installation hole to the area around the anchor claw 24. After the cement grout solidifies, it can further improve the anchoring strength.

[0029] In this embodiment, a support cylinder 211 is fixedly connected to the bottom inner end of the anchor bolt sleeve 21. The outer wall of the support cylinder 211 is in close contact with the inner wall of the anchor bolt sleeve 21. A receiving hole with an gradually increasing inner diameter from bottom to top is opened in the center of the support cylinder 211 to receive the second spring 23. The top end of the support cylinder 211 is used to support and limit the support column 22. During the opening process of the anchor claw 24, the top rod 26 pushes the support column 22 downward until the bottom end of the support column 22 abuts against the top end of the support cylinder 211. At this time, the support column 22 can no longer move downward, so that the upper surface of the support column 22 can fit tightly against the lower surface of the top rod 26, thereby preventing cement grout leakage.

[0030] In this embodiment, the number of slurry outlet holes 210 is the same as the number of strip grooves 221, and each slurry outlet hole 210 is set in the corresponding strip groove 221.

[0031] In this embodiment, the bottom surface of the top rod 26 is provided with a cylindrical protrusion on the periphery of the first grouting channel 27, and the top surface of the support column 22 is provided with a cylindrical groove that matches the cylindrical protrusion on the periphery of the second grouting channel 28. The cylindrical protrusion and the cylindrical groove are connected to prevent cement grout leakage. A sealing gasket is provided on the bottom surface of the cylindrical groove to further improve the sealing performance and prevent cement grout leakage.

[0032] In this embodiment, four connecting ears 212 are fixedly connected to the top of the side wall of the anchor bolt sleeve 21. The four connecting ears 212 are evenly distributed in the circumference and are used to connect the corresponding reinforcing steel wire rope 3.

[0033] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
