Description

Technical Field

[0001] This application relates to the field of highway subgrades, and particularly to a highway subgrade slope reinforcement device. Background Art

[0002] At present, the highway subgrade slope refers to the inclined plane part where both sides of the highway subgrade are connected to the original ground. Its function is to ensure the stability and drainage of the subgrade. Due to the influence of various factors such as geological conditions, climate change, and construction quality, problems such as landslides, collapses, and spalling may occur on the slope. These problems not only affect the normal use of the road but also may pose safety hazards. Therefore, strengthening the highway subgrade slope can effectively improve the slope stability, reduce soil erosion, prevent slope instability, and thus ensure the smoothness and safety of road traffic.

[0003] Existing slope reinforcement devices usually connect the slope to the stable stratum through anchor cables. By driving anchor rods or anchor cables into the slope, the friction and adhesion between the anchor body and the slope soil are utilized to improve the slope stability.

[0004] The above-mentioned existing technical solutions have the following defects: When using the existing anchoring and reinforcement method to reinforce the subgrade slope, during long-term use, gaps are generated between the anchor cable and the anchor hole, resulting in a reduction in the reinforcement effect of the anchor cable on the slope and a decrease in slope stability. Utility Model Content

[0005] This application provides a highway subgrade slope reinforcement device in order to enable the slope reinforcement device to reinforce the slope for a long time and avoid frequently checking the state of the reinforcement device.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A highway subgrade slope reinforcement device includes an installation cylinder, an anchor cable, and a continuous support component. The installation cylinder is vertically arranged in the slope body. The anchor cable is arranged in the installation cylinder. The continuous support component is arranged in the installation cylinder. The continuous support component includes a hinged plate, a telescopic frame, a movable plate, a pressing plate, and a gravity component. The hinged plate is sleeved on the lower part of the peripheral wall of the anchor cable. The telescopic frame includes two square columns with their ends hinged to each other. One end of the telescopic frame is hinged to the plate surface of the hinged plate. The movable plate is rotatably arranged on the peripheral wall of the installation cylinder. The hinged part of the square columns abuts against the plate surface of the movable plate. The pressing plate is slidably sleeved on the anchor cable. The other end of the telescopic frame is hinged to the plate surface of the pressing plate. The gravity component is slidably sleeved on the anchor cable and is located above the pressing plate.

[0008] By adopting the above technical solution, by setting the installation tube, anchor cable, hinged plate, telescopic frame, movable plate, pressure plate and gravity member, the installation tube and anchor cable can reinforce the slope, the gravity member presses the pressure plate downward under the action of gravity, the pressure plate compresses the telescopic frame to make the roller slide on the movable plate surface along the length direction of the movable plate, so that the movable plate moves out of the installation tube, the movable plate is away from the plate surface of the telescopic frame and presses against the soil layer in the slope body, the gravity member can continuously give pressure to the pressure plate so that the movable plate always reinforces the installation tube. The continuous support assembly can make the installation tube reinforce the slope during long-term use, avoid the occurrence of landslides, collapses, peeling and other problems on the slope, and avoid frequent inspection of the status of the slope reinforcement device.

[0009] Optionally, the continuous support assembly further includes a roller, and the roller is disposed at the hinge of the square column, and a peripheral wall of the roller is in contact with a surface of the movable plate.

[0010] By adopting the above technical solution and arranging rollers, the telescopic frame can be better supported against the surface of the movable plate, thereby avoiding damage to the telescopic frame caused by the slope reinforcement device after long-term use, and improving the supporting effect of the movable plate on the mounting tube.

[0011] Optionally, the slope reinforcement device further comprises a conical cover, wherein the conical cover is arranged at the lower end of the installation tube, and the lower end of the anchor cable is fixedly connected to the tip of the inner wall of the conical cover.

[0012] By adopting the above technical solution and providing a conical cover, the reinforcement net can fit closely to the slope, thereby reinforcing the slope and avoiding problems such as landslide, collapse, and peeling of the slope.

[0013] Optionally, a sealing groove is formed on the end surface of the conical cover, and the end of the mounting tube is adapted to the sealing groove and inserted into the sealing groove.

[0014] By adopting the above technical solution and providing a sealing groove, the installation of the conical cover and the installation cylinder can be made tighter and more secure, thereby improving the reinforcement effect.

[0015] Optionally, the slope reinforcement device further comprises a reinforcement net, wherein the reinforcement net is arranged on the slope surface of the slope body, and the installation tube and the upper end of the anchor cable are fixedly connected to the reinforcement net.

[0016] By adopting the above technical solution and setting a reinforcement net, the slope body can be reinforced, the stability of the slope body can be enhanced, and landslides and collapses of the slope body can be prevented.

[0017] Optionally, the slope reinforcement device further includes a drainage member, and the drainage member is arranged at the lower part of the reinforcement net.

[0018] By adopting the above technical solution, the drainage member can support the reinforcement net, preventing the reinforcement net and the embedding component from shifting during long-term use.

[0019] Optionally, the side wall of the drainage member is inclined inward to form an inclined surface, and the inclined surface is attached to the lower side wall of the reinforcement net.

[0020] By adopting the above technical solution, forming the inclined surface can provide more stable support for the reinforcement net, preventing the reinforcement net and the embedding component from shifting during long-term use.

[0021] Optionally, a drainage groove is provided on the upper surface of the drainage member.

[0022] By adopting the above technical solution, opening the drainage groove can effectively drain the groundwater and precipitation around the slope, reducing the influence of moisture on the slope stability, thereby improving the water resistance and stability of the slope.

Detailed implementation manners

[0032] The following further describes the present application in detail with reference to the accompanying drawings.

[0033] An embodiment of the present application discloses a highway subgrade slope reinforcement device. Refer to Figure 1 , Figure 2 and Figure 3 , the slope reinforcement device includes a reinforcement component 1, an embedding component 2 and a continuous support component 3. The reinforcement component 1 and the embedding component 2 can reinforce the slope body 44, enhance the stability of the slope body 44, and prevent the slope body 4 from landsliding and collapsing. The continuous support component 3 can keep the embedding component 2 stably connected to the soil layer of the slope body 4 all the time, and improve the reinforcement effect of the slope reinforcement device during long-term use.

[0034] Refer to Figure 1 , the reinforcement component 1 includes a reinforcement net 11 and a drainage member 12. The reinforcement net 11 is arranged on the slope surface of the slope body 4. The reinforcement net 11 is a rectangular net structure formed by welding multiple square steel bars. The surface of the reinforcement net 11 fits the slope surface of the slope body 4. The reinforcement net 11 can reinforce the slope and prevent large-area soil erosion on the slope, interfering with the daily use of the highway. The drainage member 12 is arranged between the slope body 4 and the highway body 5, at the lower part of the slope. The drainage member 12 is a square column 321 made of concrete. The drainage member 12 is embedded in the roadbed. One side wall of the drainage member 12 is attached to the side of the highway body 5. The upper end of the other side wall of the drainage member 12 is processed to be inclined inward to form an inclined surface, and the inclined surface is attached to the lower side wall of the reinforcement net 11. The drainage member 12 can support the reinforcement net 11 to prevent the reinforcement net 11 and the embedding component 2 from shifting during long-term use. A drainage groove 121 is formed on the upper surface of the drainage member 12. The length direction of the drainage groove 121 is always parallel to the length direction of the drainage member 12. The drainage groove 121 can effectively drain the groundwater and precipitation around the slope, reduce the influence of moisture on the slope stability, and thus improve the water resistance and stability of the slope.

[0035] Combined with Figure 1 and Figure 2, the embedding assembly 2 includes an installation cylinder 21 and a conical cover 22. A plurality of vertical cylindrical anchor holes are provided on the slope body 4. The installation cylinder 21 is vertically installed in the anchor holes, and one end of the installation cylinder 21 is fixedly connected to the surface of the slope that fits the connection node of the square rod of the reinforcement mesh 11. The conical cover 22 is arranged at the end of the installation cylinder 21 facing away from the reinforcement mesh 11. An annular sealing groove 221 is formed on the end face of the conical cover 22. The sealing groove 221 is coaxially arranged with the conical cover 22. The sealing groove 221 is adapted to the end of the installation cylinder 21 and the end of the installation cylinder 21 is inserted into the sealing groove 221. The sealing groove 221 can make the installation of the conical cover 22 and the installation cylinder 21 tighter and more firm, improving the reinforcement effect.

[0036] Combined with Figure 2 and Figure 3 , the embedding assembly 2 further includes a cable 23. The cable 23 is arranged in the installation cylinder 21. The cable 23 is a cylinder. One end of the cable 23 is fixedly connected to the surface of the slope that fits the connection node of the square rod of the reinforcement mesh 11. The other end of the cable 23 is fixedly connected to the tip of the inner wall of the conical cover 22. The axis of the cable 23 coincides with the axis of the installation cylinder 21. The cable 23 can firmly fix the conical cover 22 on the installation cylinder 21. At the same time, the installation cylinder 21, the conical cover 22 and the cable 23 can make the reinforcement mesh 11 fit tightly with the slope, reinforce the slope, and avoid problems such as landslides, collapses, and spalling of the slope.

[0037] Combined with Figure 3 and Figure 4 , the continuous support assembly 3 includes a hinge plate 31, a telescopic frame 32, a roller 33 and a movable plate 34. The hinge plate 31 is sleeved on the peripheral wall of the cable 23 and is located inside the conical cover 22. The hinge plate 31 is an annular plate, and the axis of the hinge plate 31 coincides with the axis of the cable 23. The telescopic frame 32 is arranged above the hinge plate 31 and is located inside the installation cylinder 21. The telescopic frame 32 is formed by connecting two square columns 321. One end of the two square columns 321 is hinged to each other through a connecting shaft (not shown in the figure). The length direction of the connecting shaft is perpendicular to the side wall of the square column 321. One end of the telescopic frame 32 is hinged to the plate surface of the hinge plate 31 close to the reinforcement mesh 11. The roller 33 is arranged at the hinge of the square column 321 of the telescopic frame 32, and the axis of the roller 33 is perpendicular to the side wall of the square rod. A rectangular installation hole 211 is formed on the peripheral wall of the installation cylinder 21. The installation hole 211 communicates with the inside and outside of the installation cylinder 21. The end face of the movable plate 34 is hinged to the end of the hole wall of the installation hole 211. The peripheral wall of the roller 33 slides and fits the plate surface of the movable plate 34.

[0038] Referring to Figure 3, the continuous support component 3 further includes a pressing plate 35 and a gravity member 36. The pressing plate 35 is slidably sleeved on the peripheral wall of the anchor cable 23. The pressing plate 35 is an annular plate and is coaxially arranged with the anchor cable 23. There is a gap between the outer peripheral wall of the pressing plate 35 and the inner wall of the installation cylinder 21. The end of the telescopic frame 32 away from the hinge plate 31 is hinged on the plate surface of the pressing plate 35 close to the conical cover 22. The gravity member 36 is slidably sleeved on the anchor cable 23. The gravity member 36 is located above the pressing plate 35. The gravity member 36 is preferably made of a metal with a high density. The outer peripheral wall of the gravity member 36 is in contact with the inner wall of the installation cylinder 21, and the end face of the gravity member 36 is in contact with the plate surface of the pressing plate 35 facing away from the conical cover 22.

[0039] Combined with Figure 2 and Figure 3 , under the action of gravity, the gravity member 36 presses the pressing plate 35 downward. The pressing plate 35 compresses the telescopic frame 32, causing the roller 33 to slide along the length direction of the movable plate 34 on the plate surface of the movable plate 34, so that the movable plate 34 moves outward from the installation cylinder 21. The plate surface of the movable plate 34 facing away from the telescopic frame 32 abuts against the soil layer in the slope body 4. The gravity member 36 can continuously apply pressure to the pressing plate 35, so that the movable plate 34 always reinforces the installation cylinder 21. The continuous support component 3 can enable the installation cylinder 21 to reinforce the slope during long-term use, avoid problems such as landslides, collapses, and spalling of the slope, and avoid frequently checking whether the installation cylinder 21 is firmly attached to the slope.

After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
