Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically a slope protection structure. Background Technology

[0002] Slope protection structures are protective facilities designed for various slopes in engineering construction, such as roads, water conservancy projects, and mines. Their core purpose is to prevent slope instability disasters such as landslides, collapses, and rockfalls caused by natural factors (rainfall, weathering, earthquakes) or human activities (excavation, loading) through physical, mechanical, or ecological means such as active restraint (e.g., anchor bolts, anchor cables), passive interception (e.g., anti-slide piles, protective nets), and covering and diversion (e.g., vegetation nets, seepage trenches). This ensures the safety of surrounding personnel and facilities, reduces soil erosion caused by rainwater and wind erosion, and protects the slope's structure. In addition, ecological protection measures can restore slope vegetation, harmonize the project with the natural environment, and ensure the stable operation of basic engineering functions such as road traffic and water conservancy facilities.

[0003] In the initial stage of ecological protection slope protection, since the vegetation within the ecological grid has not yet formed a stable protection system, it is very easy for soil erosion to occur once heavy rainfall occurs. Therefore, we propose a slope protection structure to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a slope protection structure that solves the problem of soil erosion in the initial stage of ecological slope protection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slope protection structure, comprising a slope body, a retaining wall provided on the outer surface of the slope body, a barrier plate connected to the upper surface of the retaining wall, three drainage channels provided on the outer surface of the retaining wall, a water channel connected to the outer surface of the retaining wall, the interior of each drainage channel communicating with the outer surface of the water channel, four ecological grids provided on the upper surface of the retaining wall, a waterproof board connected to the outer surface of each ecological grid, and a vegetation net provided inside each ecological grid.

[0006] Furthermore, a transverse connecting block is provided on the bottom surface of the slope body, and the upper surface of the transverse connecting block is connected to the bottom surface of the retaining wall.

[0007] Furthermore, the retaining wall and the slope body together have multiple mounting holes, and each mounting hole is equipped with a hollow tube.

[0008] Furthermore, each hollow tube has a discharge port on its outer surface, and mortar can be poured into the interior of each hollow tube.

[0009] Furthermore, each hollow tube has a pad on its outer surface, the bottom surface of each pad is in contact with the outer surface of the retaining wall, and each hollow tube has a bolt threaded to the end away from the discharge port.

[0010] Furthermore, the slope body is equipped with three drainage pipes. The end of each drainage pipe that is away from the slope body passes through the retaining wall and extends to the outer surface of the retaining wall. The outer surface of the drainage pipe is connected to the drainage channel.

[0011] Furthermore, the outer surface of the drain pipe has two water inlet holes, and the inner wall of the drain pipe is connected to two isolation pipes, each of which has a filter hole on its outer surface.

[0012] Compared with the prior art, the present invention provides a slope protection structure with the following beneficial effects:

[0013] This utility model, through the interception and diversion function of the top barrier plate, can guide rainwater and slope runoff from the surface of the slope to the pre-set drainage channel of the retaining wall, and then collect them into the water channel and discharge them outside the slope. This prevents water from directly eroding the ecological grid from the source. At the same time, the waterproof plate on the outside of the ecological grid can further block the intrusion of a small amount of side seepage water, while the vegetation net inside can stabilize the planting soil and seedlings in the grid, forming a multi-layer protection of diversion, barrier and soil stabilization, effectively controlling soil and water loss in the early stage of ecological protection.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This embodiment of a slope protection structure includes a slope body 1, with a retaining wall 2 installed on the outer surface of the slope body 1. The retaining wall 2 directly bears the lateral pressure of the slope body 1 and can block the displacement of the surface and shallow soil, preventing the overall collapse or partial collapse of the slope body 1. At the same time, the retaining wall 2 is the hub connecting the reinforcement system, drainage system, and ecological protection system, and achieves functional coordination of each component through its own structural design. A barrier plate 3 is connected to the upper surface of the retaining wall 2, which can block the rainwater runoff collected on the surface of the slope body 1. The water is guided to three pre-set drainage channels 4 on the outer surface of the retaining wall 2, preventing rainwater from flowing freely on the slope body 1 or the top of the retaining wall 2. This cuts off the path of water flow directly eroding the ecological grid 6 at the source, reducing the risk of soil erosion within the ecological grid 6. Three drainage channels 4 are provided on the outer surface of the retaining wall 2, and a water channel 5 is connected to the outer surface of the retaining wall 2. The water channel 5 is directly connected to the three drainage channels 4 on the outer surface of the retaining wall 2, allowing rainwater collected from the surface of the slope body 1 by the drainage channels 4, runoff diverted by the barrier plate 3, and deep groundwater discharged from the drainage pipe 15 to be drained through the drainage system. The drainage channel 4 collects and transports water to a designated discharge area outside the slope. The interior of each drainage channel 4 is connected to the outer surface of the water channel 5. Four ecological grids 6 are formed on the upper surface of the retaining wall 2. The outer surface of each ecological grid 6 is connected to a waterproof board 7. The waterproof board 7 is a key waterproof barrier for the ecological grid 6. It is set in close contact with the outer surface of the ecological grid 6 to block the intrusion of residual rainwater after drainage by the barrier plate 3 and drainage channel 4, as well as the intrusion of side seepage water from the retaining wall 2. It resists the impact of short-term strong water flow to avoid the loss of planting soil, and at the same time reduces excessive evaporation of water in the ecological grid 6. To prevent external mud and sand from contaminating the substrate and maintain a suitable environment for vegetation growth, each ecological cell 6 is equipped with a vegetation net 8. The vegetation net 8 is laid in the planting soil within the ecological cell 6. Its interwoven mesh can tightly wrap the soil particles, preventing the planting soil from being washed away by runoff due to heavy rainfall. When the seeds in the ecological cell 6 germinate into seedlings, the vegetation net 8 becomes a support and fixing carrier for the seedlings' growth. The seedlings are prevented from falling over due to wind, rain or slight water flow by the support of the net. Especially in windy and rainy areas, it can effectively reduce the lodging rate of seedlings.

[0022] The bottom surface of the slope body 1 is provided with a transverse connecting block 9. The upper surface of the transverse connecting block 9 is connected to the bottom surface of the retaining wall 2. The transverse connecting block 9 is set on the bottom surface of the slope body 1 and is tightly connected with the bottom surface of the retaining wall 2 to form a trapezoidal structure. From a mechanical point of view, the center of gravity of the trapezoidal structure is lower and the bottom support width is significantly increased, which can effectively disperse the lateral thrust of the slope body 1 borne by the retaining wall 2 and prevent the retaining wall 2 from overturning and deforming at the bottom due to excessive force on one side. Especially for slopes with steep slopes or large soil pressure, the overturning safety factor of the retaining wall 2 can be improved, providing a stable bottom support for the entire protection structure.

[0023] Multiple mounting holes 10 are provided inside the retaining wall 2 and the slope body 1. Each mounting hole 10 contains a hollow tube 11. In this slope protection structure, the hollow tube 11 is the core component for deep reinforcement of the retaining wall 2 and the slope body 1. After being inserted into the two through the mounting holes 10, the mortar injected into the tube will penetrate into the slope gap through the outlet 12 and solidify to form a rigid anchor point to enhance the internal shear strength of the slope. At the same time, the pad 13 on the outer surface of the hollow tube 11 can increase the bearing area. With the threaded connection of the bolts 14, the retaining wall 2 and the hollow tube 11 are firmly fixed to avoid relative displacement. Finally, in conjunction with the foundation stabilization effect of the transverse connecting block 9, the anti-sliding and anti-overturning capabilities of the entire protection structure are improved.

[0024] Each hollow tube 11 has a discharge port 12 on its outer surface, and mortar can be poured into the interior of each hollow tube 11.

[0025] Each hollow tube 11 has a pad 13 on its outer surface, and the bottom surface of each pad 13 is in contact with the outer surface of the retaining wall 2. Each hollow tube 11 has a bolt 14 threadedly connected to the end away from the discharge port 12.

[0026] The slope body 1 is equipped with three drainage pipes 15. The end of each drainage pipe 15 away from the slope body 1 passes through the retaining wall 2 and extends to the outer surface of the retaining wall 2. The outer surface of the drainage pipe 15 is connected to the drainage channel 4. The slope body 1 is prone to groundwater accumulation due to rainfall infiltration and rising groundwater level. Excessive pore water pressure will significantly reduce the shear strength of the soil and induce landslides or surface soil loss. The three drainage pipes 15 embedded in the slope body 1 can collect groundwater in the surrounding soil through the water inlet holes 16 opened on their outer surfaces, and gather the dispersed groundwater into a concentrated water flow, so as to avoid the continuous accumulation of water in the slope and reduce the destructive effect of groundwater on the slope structure from the root.

[0027] The drainage pipe 15 has two inlet holes 16 on its outer surface and two isolation pipes 17 connected to its inner wall. Each isolation pipe 17 has a filter hole 18 on its outer surface. When groundwater enters the pipe through the inlet holes 16 on the outer surface of the drainage pipe 15, the isolation pipe 17 acts as an interceptor. Its cylindrical structure, which fits the inner wall of the drainage pipe 15, can directly block large particles such as stones and coarse sand carried in the groundwater, preventing such impurities from entering the drainage pipe 15 channel. Without the isolation pipe 17, large particles of impurities are prone to deposit in the pipe, which can lead to a reduction in the pipe cross-section or even complete blockage in the long term. This would cause the drainage pipe 15 to lose its deep drainage function, thereby causing risks such as increased pore water pressure and soil softening inside the slope body 1. The groundwater filtered by the isolation pipe has a low sand content and will not cause siltation in the drainage channel 4 after flowing into it. It also prevents silt from entering the water channel 5 with the water flow and causing blockage of the water channel 5.

[0028] The working principle of the above embodiments is as follows:

[0029] This slope protection structure forms an integrated protection system through the coordinated operation of its various components. The transverse connecting block 9 makes the retaining wall 2 trapezoidal to enhance stability. The hollow pipe 11 can be filled with mortar, which seeps into the slope body 1 from the outlet 12. After the mortar solidifies, it works with the bolts 14 and the pad 13 to achieve deep reinforcement of the retaining wall 2 and the slope body 1. For drainage, the barrier plate 3 guides rainwater on the slope body 1 to the drainage channel 4, and then discharges it through the water channel 5. The drainage pipe 15 collects deep groundwater from the slope through the inlet hole 16, the isolation pipe 17 and the filter hole 18 and flows into the drainage channel 4 for discharge. For ecological protection, the waterproof plate 7 outside the ecological grid 6 blocks water intrusion. The internal vegetation net 8 initially fixes the planting soil and later assists the growth of vegetation roots, ultimately achieving slope stabilization and ecological restoration.

[0030] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
