Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering technology, and more specifically, to a slope reinforcement device for geotechnical engineering. Background Technology

[0002] With the rapid development of infrastructure construction in my country, a large number of highway, railway, and building projects involve slope engineering. Due to the complexity of the soil and rock mass itself and the influence of natural and human factors, slopes are prone to deformation, sliding and other instability, which threatens the safety and normal use of the project, and may even cause serious harm to the surrounding environment and people's lives and property. In order to ensure the stability of the slope and improve its resistance to deformation and sliding, slope reinforcement devices for geotechnical engineering have emerged. Existing devices that reinforce rock slopes with a single reinforcement nail or a single anchor cannot simultaneously reinforce the interior and surface of the rock slope in multiple layers, thus the reinforcement devices have certain limitations.

[0003] A search revealed that CN222834931U discloses a slope reinforcement device for geotechnical engineering. This device is applied to a slope, with a top concrete block at the top and a bottom concrete block at the bottom. A spliced ​​protective plate is installed on the slope surface. The upper and left sides of the spliced ​​protective plate have insertion protrusions, and the right and lower sides have insertion grooves corresponding to the insertion protrusions. Fixing nails are installed between the spliced ​​protective plates to achieve vertical connection. Square grooves are provided on both sides of the top surface of the spliced ​​protective plate, and inclined pressure plates are installed within these grooves. The ends of the inclined pressure plates are fixedly connected to the top and bottom concrete blocks, respectively. Joint fixing nails are provided between adjacent inclined pressure plates. A circular hole is provided in the middle of the spliced ​​protective plate, and a cement blanket and vegetation soil layer are placed over the circular hole. The reinforcement effect is relatively stable, and it will not loosen under long-term external force and the stress of the overall slope inclination. In the process of realizing this utility model, the inventors discovered the following problems with the prior art:

[0004] Existing single-stabilizing nail devices for reinforcing geotechnical slopes can only fix loose rocks on the slope surface and cannot transfer the landslide load to stable rock layers. In contrast, single-anchor reinforcement devices do the opposite. Furthermore, the traditional waterproofing measures for rock slope reinforcement devices involve digging a waterproof pit of a certain depth at the bottom of the landslide. During heavy rain, water on the slope slides down into the pit and then seeps into the ground. However, if the water in the pit cannot seep into the ground within a certain time, the rainwater in the pit will accumulate and overflow from the waterproof pit, causing local flooding in the construction area.

[0005] Therefore, a slope reinforcement device for geotechnical engineering is proposed to address the above-mentioned problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a slope reinforcement device for geotechnical engineering to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a slope reinforcement device for geotechnical engineering, comprising a drainage component, a sealing component, an anti-slip component, and a fixing component. The drainage component is installed at the slope water collection point, and sealing components are installed on both sides of the drainage component by bolts. The fixing component is installed on the slope surface, and an anti-slip component is fixedly connected above the fixing component.

[0008] Preferably, the drainage assembly includes a drainage trough plate, a connecting block, and drainage holes, with the connecting block installed above the drainage trough plate and drainage holes drilled into the side wall of the drainage trough plate.

[0009] Preferably, the sealing assembly includes a sealing rubber ring, a connecting pipe, and a drain valve, wherein the connecting pipe is installed on the side of the sealing rubber ring, and the drain valve is installed on the side of the connecting pipe away from the sealing rubber ring.

[0010] Preferably, the anti-slip component includes anti-slip posts, a steel mesh assembly, and a sprayed concrete layer, wherein the inner wall of the sprayed concrete layer is fitted with a steel mesh assembly, and the side of the steel mesh assembly is fixedly fitted with an anti-slip post.

[0011] Preferably, the steel mesh assembly includes horizontal bars, vertical bars, and binding wires, and the inner diameter surface of the binding wires is fitted with horizontal bars, and the sides of the horizontal bars are fitted with vertical bars.

[0012] Preferably, the fixing component includes reinforcing nails, anchor bolts, and a shotcrete layer, wherein reinforcing nails are installed on the inner wall surface of the shotcrete layer, and anchor bolts are connected below the reinforcing nails.

[0013] Preferably, the reinforcing nail includes a connecting rod, a fixing rod, and a cone, and the fixing rod is installed on the side of the connecting rod, and the cone is installed on the side of the fixing rod away from the connecting rod.

[0014] Preferably, the anchor bolt includes a connecting sleeve, a rod body, and a fixing plate, wherein the rod body is mounted on the side of the fixing plate, and the connecting sleeve is mounted on the side of the rod body away from the fixing plate.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] Compared with existing technologies, this geotechnical engineering slope reinforcement device uses anchor rods and reinforcement nails of the fixing components simultaneously. It can not only fix the loose surface soil and rock of the slope and limit local slippage and weathering, but also transfer the sliding load to the stable rock layer, thus achieving multi-level slope reinforcement.

[0017] Compared with existing technologies, this geotechnical engineering slope reinforcement device, through the cooperation of drainage components and sealing components, allows workers to manually drain the water from the drainage channel by connecting a water pump to a drainage valve when water overflows, thereby preventing the construction area from being flooded.

The fixing component 4 is set at the slope surface, and the anti-slip component 3 is fixedly connected to the top of the fixing component 4.

After drainage component 1 solidifies, workers need to install and spray fixing component 4 on the surface of the rock slope to initially fix the rock slope. After the sprayed fixing component 4 solidifies, workers need to install and spray anti-slip component 3 on the surface of fixing component 4 to fix the slope a second time. Example

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, the drainage component 1 includes a drainage channel plate 5, a connecting block 6, and a drainage hole 7. The connecting block 6 is installed on the top of the drainage channel plate 5, and the drainage hole 7 is drilled in the side wall of the drainage channel plate 5. When workers need to build the drainage component 1 at the bottom of the rock slope according to the design, they need to first use concrete to build the drainage channel plate 5 at the bottom of the rock slope. After the drainage channel plate 5 solidifies, the workers need to build the connecting block 6 above the drainage channel plate 5 and connect it to the rock slope according to the design. The width of the connecting block 6 is the thickness of the concrete sprayed on the fixing component 4 and the anti-slip component 3. After the connecting block 6 solidifies, the workers also need to drill the drainage hole 7 on one side of the drainage channel plate 5 and install the sealing component 2 at the drainage hole 7.

[0028] In a preferred embodiment, the sealing assembly 2 includes a sealing rubber ring 8, a connecting pipe 9, and a drain valve 10. The connecting pipe 9 is installed on the side of the sealing rubber ring 8, and the drain valve 10 is installed on the side of the connecting pipe 9 away from the sealing rubber ring 8. The sealing rubber ring 8 and the connecting pipe 9 are interference fit. The connecting pipe 9 and the drain valve 10 are connected by a flange. When the worker needs to install the sealing assembly 2 at the drain hole 7, the worker needs to put the connecting pipe 9 into the drain hole 7, and then move the sealing rubber ring 8 along the outer diameter of the drain hole 7 to the gap between the connecting pipe 9 and the drain hole 7. Then, the worker re-seals the position of the connecting pipe 9 and the drain hole 7 with concrete. After the concrete has solidified, the worker also needs to install the drain valve 10 on the other side of the connecting pipe 9 through the flange.

[0029] In a preferred embodiment, the anti-slip component 3 includes anti-slip posts 11, a steel mesh assembly 12, and a sprayed concrete layer 13. The steel mesh assembly 12 is installed on the inner wall of the sprayed concrete layer 13, and the anti-slip posts 11 are fixedly installed on the side of the steel mesh assembly 12. When the worker needs to install and spray the anti-slip component 3 on the surface of the fixing component 4, he / she first needs to assemble the steel mesh assembly 12, and then weld the exposed part of the fixing component 4 to the steel mesh assembly 12. After the welding is completed, the worker also needs to spray a layer of sprayed concrete layer 13 on the surface of the steel mesh assembly 12 according to the design. After the sprayed concrete layer 13 solidifies, the worker needs to build the anti-slip posts 11 on the sprayed concrete layer 13. After the anti-slip posts 11 are built, the worker also needs to spray another layer of sprayed concrete layer 13 on its surface to fix it.

[0030] In a preferred embodiment, the steel mesh assembly 12 includes horizontal bars 14, vertical bars 15, and binding wires 16. Horizontal bars 14 are installed on the inner diameter surface of the binding wires 16, and vertical bars 15 are installed on the sides of the horizontal bars 14. When workers splice the steel mesh assembly 12, they need to arrange the vertical bars 15 and horizontal bars 14 according to the design so that the horizontal bars 14 and vertical bars 15 are equidistant. Then, the binding wires 16 are used to fix the two. After fixing, the workers need to weld them to the exposed parts of the fixing assembly 4.

[0031] In a preferred embodiment, the fixing component 4 includes reinforcing nails 17, anchor rods 18, and a primary shotcrete layer 19. The reinforcing nails 17 are installed on the inner wall surface of the primary shotcrete layer 19, and the anchor rods 18 are placed below the reinforcing nails 17. When the worker needs to install and spray the fixing component 4 on the surface of the rock slope, he needs to insert the anchor rods 18 into the rock slope through drilling, and then inject concrete into the drilling holes to fix the anchor rods 18. After the anchor rods 18 are fixed, the worker needs to drive the reinforcing nails 17 into the rock slope to fix the surface of the rock slope. After the reinforcing nails 17 and anchor rods 18 are installed, the worker needs to spray a layer of primary shotcrete layer 19 on the surface of the rock slope.

[0032] In a preferred embodiment, the reinforcing nail 17 includes a connecting rod 20, a fixing rod 21, and a cone 22. The fixing rod 21 is welded to the side of the connecting rod 20, and the cone 22 is welded to the side of the fixing rod 21 away from the connecting rod 20. When the worker needs to drive the reinforcing nail 17 into the rock slope, he needs to drill a hole on the surface of the rock slope according to the design and clean the inside of the hole. Then, the cone 22 and the fixing rod 21 of the reinforcing nail 17 are inserted into the rock slope, while the connecting rod 20 needs to be exposed. After the insertion is completed, the worker needs to use concrete to inject into the hole to fix the reinforcing nail 17.

[0033] In a preferred embodiment, the anchor rod 18 includes a connecting sleeve 23, a rod body 24, and a fixing plate 25. The rod body 24 is welded to the side of the fixing plate 25, and the connecting sleeve 23 is installed on the side of the rod body 24 away from the fixing plate 25. The rod body 24 and the connecting sleeve 23 are interference fit. When the worker needs to insert the anchor rod 18 into the rock slope, the worker needs to use the connecting sleeve 23 to connect the rod body 24 according to the design, so that the length of the rod body 24 meets the depth required to penetrate the rock layer in the design. After the connection is completed, the worker needs to drill a hole on the surface of the rock slope and clean the hole. Then, the anchor rod 18 is put into the drill hole, leaving a part exposed. At this time, the worker needs to inject concrete into the hole to fix the anchor rod 18. The worker needs to weld the fixing plate 25 to the exposed rod body 24 so that it can be connected to the steel mesh assembly 12.

[0034] The working process of this utility model is as follows: First, when it is necessary to reinforce the rock slopes on both sides of the construction area, the workers need to clean the loose stones on the surface of the rock slope and trim the rock slope according to the design. Then, the drainage component 1 is installed at the bottom of the rock slope. When the workers need to build the drainage component 1 at the bottom of the rock slope according to the design, they need to first use concrete to build a drainage channel plate 5 at the bottom of the rock slope. After the drainage channel plate 5 solidifies, the workers need to build a connecting block 6 above the drainage channel plate 5 and connect it to the rock slope according to the design. The width of the connecting block 6 is the thickness of the concrete sprayed on the fixing component 4 and the anti-slip component 3. After the connecting block 6 solidifies, the workers also need to drill a drainage hole 7 on one side of the drainage channel plate 5 and install a sealing component 2 at the drainage hole 7. At this time, the workers need to put the connecting pipe 9 into the drainage hole 7, and then move the sealing rubber ring 8 along the outer diameter of the drainage hole 7 to the gap between the connecting pipe 9 and the drainage hole 7. Then, the workers need to re-seal the position of the connecting pipe 9 and the drainage hole 7 with concrete. After the concrete has solidified, the workers need to install the drain valve 10 on the other side of the connecting pipe 9 through the flange, and seal the sealing component 2 on one side of the drainage component 1. After the drainage component 1 has solidified, the workers need to install and spray the fixing component 4 on the surface of the rock slope. First, the workers need to use the connecting sleeve 23 to connect the rod 24 according to the design, so that the length of the rod 24 meets the depth required to penetrate the rock layer in the design. After the connection is completed, the workers need to drill holes on the surface of the rock slope and clean the holes. Then, the anchor rod 18 is put into the drill hole, leaving part of it exposed. At this time, the workers need to inject concrete into the hole to fix the anchor rod 18. The exposed rod 24 needs to be welded with a fixing plate 25 so that it can be connected to the steel mesh component 12. After the anchor rod 18 is fixed, it needs to drill holes again on the surface of the rock slope according to the design and clean the inside of the drill hole. Then, the cone 22 of the reinforcing nail 17 and the fixing rod 21 part are implanted into the rock slope, while the connecting rod 20 part needs to be exposed.

[0035] After implantation, workers need to use concrete injection drilling to fix the reinforcing nails 17. After the reinforcing nails 17 and anchor rods 18 are installed, workers need to spray a layer of initial shotcrete 19 onto the surface of the rock slope to initially fix it. After the sprayed fixing components 4 have solidified, workers need to install and spray anti-slip components 3 on the surface of the fixing components 4 to fix the slope a second time. This requires assembling the steel mesh components 12 first. During assembly, the vertical bars 15 and horizontal bars 14 need to be arranged according to the design, so that the horizontal bars 14 and the vertical bars 15 are equal in height. The steel mesh assembly 12 is arranged at intervals, and then the two are fixed together using binding steel wire 16. After the fixing is completed, the workers need to weld it to the exposed anchor rod 18 and fixing nail of the fixing component 4. After the welding is completed, the workers also need to spray a layer of sprayed concrete 13 on the surface of the steel mesh assembly 12 according to the design. After the sprayed concrete 13 solidifies, the workers need to build anti-slip columns 11 on the sprayed concrete 13. After the anti-slip columns 11 are built, the workers need to spray another layer of sprayed concrete 13 on their surface to fix them. The above is the working principle of the geotechnical engineering slope reinforcement device.
