Description

Technical Field

[0001] This application relates to the field of ecological restoration technology for mine slopes, and in particular to a greening and planting device for ecological restoration of mine slopes. Background Technology

[0002] Mining activities have led to extensive exposure of slopes, causing problems such as soil erosion and ecological damage.

[0003] Currently, slope ecological restoration technologies mainly include methods such as hydroseeding, vegetation bags, and three-dimensional mesh planting. These technologies are effective in the early stages of vegetation restoration, but their long-term stability is poor, especially on steep slopes or infertile soil conditions, where vegetation survival rates are low and growth is slow. In recent years, with increasingly stringent environmental protection requirements, the demand for mine ecological restoration has become increasingly urgent, necessitating the development of a greening and planting device that can adapt to complex terrain and improve vegetation survival rates. Utility Model Content

[0004] The purpose of this application is to provide a greening and planting device for ecological restoration of mine slopes. Through the design of double-layer buffer and gradient nutrients, it not only solves the problem of soil loss on steep slopes, but also provides continuous water and nutrients for vegetation, making it more practical.

[0005] The greening and planting device for ecological restoration of mine slopes provided in this application adopts the following technical solution: A greening and planting device for ecological restoration of mine slopes includes a support component, a composite planting component, and a water supply component. The composite planting component includes a rigid protective shell and a permeable bearing layer installed on the inner wall of the rigid protective shell. A hollow buffer layer is formed between the rigid protective shell and the permeable bearing layer. The bottom surface of the rigid protective shell has evenly distributed drainage holes. A water collection trough is fixedly connected to the bottom surface of the rigid protective shell. The water collection trough is connected to the interior of the rigid protective shell through the drainage holes. A water-retaining layer is laid on the inner bottom wall of the rigid protective shell. A slow-release fertilizer layer is laid on top of the water-retaining layer. Planting soil is laid on top of the slow-release fertilizer layer.

[0006] Two water inlets are embedded between the rigid protective shell and the permeable bearing layer. A drip irrigation pipe is installed on the inner wall of the rigid protective shell. The two sides of the drip irrigation pipe are connected to the two water inlets respectively. Both sides of the water collection tank are connected to the drain outlets. A biodegradable protective net is installed on the top of the rigid protective shell.

[0007] By adopting the above technical solutions, the hollow buffer layer formed by the rigid protective shell and the permeable bearing layer can buffer the impact of rainwater or irrigation water, reduce the direct erosion of the planting soil by water flow, and, together with the drainage holes and water collection trough at the bottom, can orderly discharge excess water and reduce the risk of soil erosion. The water-retaining layer can retain water, and the slow-release fertilizer layer can continuously provide nutrients. Together with the planting soil, the two provide a stable water and fertilizer environment for vegetation growth. After the drip irrigation pipe receives water through the inlet, it can evenly supply water to the planting soil, avoiding local drought or waterlogging. The biodegradable protective net can further block the loss of soil particles in the early stage, and releases growth space naturally as it degrades in the later stage without affecting vegetation development. The overall structure effectively improves the growth conditions of vegetation on steep slopes or infertile soils through the synergy of buffering and erosion prevention, gradient supply and precision irrigation.

[0008] Preferably, the support component includes a support frame disposed below the composite planting component, and the bottom surface of the support frame is welded with evenly distributed anchor rods.

[0009] By adopting the above technical solution, the support frame is set under the composite planting component, which can provide it with stable support. The evenly distributed anchor rods can penetrate into the surface of the slope, enhance the connection strength between the overall structure and the slope, reduce the risk of device slippage caused by steep slope or complex terrain, improve long-term stability, and adapt to the complex terrain of mine slopes.

[0010] Preferably, L-shaped connecting corner brackets are installed at each of the four corners of the water collection tank, and the bottom end of the L-shaped connecting corner brackets is installed on the upper surface of the support frame.

[0011] By adopting the above technical solution, the L-shaped connecting corner seat rigidly connects the water collection tank and the support frame, which can strengthen the integrity of the composite planting component and the support component, reduce the relative loosening of the two under slope vibration or water flow impact, and further improve the structural stability of the device.

[0012] Preferably, the water supply assembly includes a water storage tank fixedly connected to the upper surface of the support frame, the top of the water storage tank is equipped with a removable top cover, and the inner wall of the water storage tank is equipped with a filter screen.

[0013] By adopting the above technical solutions, the water storage tank can store rainwater or external water sources, providing a stable water reserve for vegetation growth. The filter screen can filter out particles such as mud and sand in the water, avoiding blockage and ensuring smooth water supply. It is suitable for complex water quality scenarios in mining environments. The detachable top cover makes it convenient to clean and maintain the filter screen regularly.

[0014] Preferably, a first submersible pump is installed on the inner bottom wall of the water storage tank, and the output end of the first submersible pump is connected to a water pumping pipe, the output end of which is connected to one of the two water inlets.

[0015] By adopting the above technical solution, the first submersible pump can stably deliver water from the water storage tank to the water inlet through the pumping pipe, and then evenly distribute it to the planting soil through the drip irrigation pipe, realizing automated water supply, reducing reliance on manual irrigation, and is especially suitable for long-term maintenance of slopes in remote mines.

[0016] Preferably, a second submersible pump is installed on the inner top wall of the top cover, and a water supply pipe is connected to the top of the second submersible pump. The input end of the water supply pipe is connected to one of the two drain outlets.

[0017] By adopting the above technical solution, the second submersible pump can pump the excess water discharged from the drainage outlet in the water collection tank back to the water storage tank through the water delivery pipe, realize the recycling of water resources, save irrigation water, and enhance the applicability of the device in arid or water-scarce environments.

[0018] Preferably, the bottom of the water storage tank is connected to a drain port, and the top of the top cover is equipped with a replenishment port, the output end of which is connected to the interior of the water storage tank.

[0019] By adopting the above technical solution, the liquid replenishment and discharge of the water tank can be facilitated through the liquid replenishment and discharge ports, making it more practical.

[0020] Preferably, one of the two water inlets is connected to a water inlet inside another set of composite planting components via a pipeline, and the other of the two drain outlets is connected to a drain outlet inside another set of composite planting components via a pipeline.

[0021] By adopting the above technical solution, adjacent composite planting components can be connected through pipelines via water inlets and outlets to form an integrated irrigation and drainage network. This facilitates unified management during large-area slope restoration, improves restoration efficiency, and enhances the slope's erosion resistance through overall layout, thus promoting the integrity and stability of ecological restoration.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This greening and planting device for ecological restoration of mine slopes provides stable support for the overall structure and enhances the connection strength with the slope through the cooperation of the support frame and anchor rod in the support component. The hollow buffer layer formed by the rigid protective shell and the permeable bearing layer in the composite planting component can buffer the impact of water flow. Combined with drainage holes and water collection troughs, it reduces soil loss. The water-retaining layer, the slow-release fertilizer layer and the planting soil form a gradient nutrient supply system. Drip irrigation pipes achieve precise irrigation through the water inlet. The biodegradable protective net prevents water loss in the early stage and does not hinder growth in the later stage. The water supply component has a water storage tank and a first submersible pump and a second submersible pump to achieve water resource recycling.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1: A greening and planting device for ecological restoration of mine slopes, referring to... Figure 1 , Figure 4 and Figure 5The system includes a support component 1, a composite planting component 2, and a water supply component 3. The composite planting component 2 includes a rigid protective shell 201 and a permeable load-bearing layer 202 installed on the inner wall of the rigid protective shell 201. A hollow buffer layer 203 is formed between the rigid protective shell 201 and the permeable load-bearing layer 202. The rigid protective shell 201 is made of recycled PP plastic, which has the characteristics of resisting ultraviolet aging and acid and alkali corrosion. The permeable load-bearing layer 202 is made of long-filament non-woven fabric, which can achieve the load-bearing effect while allowing water to permeate freely. The bottom surface of the rigid protective shell 201 has evenly distributed drainage holes 204. When rainwater or irrigation water washes the composite planting component... At time 2, the water flow will enter the hollow buffer layer 203 through the permeable bearing layer 202 for deceleration, and then slowly discharge through the drainage hole 204 to avoid nutrient loss caused by direct impact on the soil. At the same time, a small amount of air can be retained in the hollow buffer layer 203 to enhance soil permeability. The bottom surface of the rigid protective shell 201 is fixedly connected to the water collection trough 205, which is connected to the interior of the rigid protective shell 201 through the drainage hole 204. The inner bottom wall of the rigid protective shell 201 is covered with a water-retaining layer 206, a slow-release fertilizer layer 207 is laid on top of the water-retaining layer 206, and planting soil 208 is laid on top of the slow-release fertilizer layer 207.

[0027] Reference Figure 3 , Figure 4 and Figure 5 Two water inlets 209 are embedded between the rigid protective shell 201 and the permeable bearing layer 202. Drip irrigation pipes 210 are installed on the inner wall of the rigid protective shell 201. The two sides of the drip irrigation pipes 210 are connected to the two water inlets 209 respectively. Drainage outlets 211 are connected to both sides of the water collection trough 205. A biodegradable protective net 212 is installed on the top of the rigid protective shell 201. The other water inlet 209 is connected to the water inlet 209 inside another set of composite planting components 2 through a pipeline. The other drainage outlet 211 is connected to the drainage outlet 211 inside another set of composite planting components 2 through a pipeline. Adjacent composite planting components 2 can be connected to the drainage outlets 211 through the water inlets 209 and drainage outlets 211 through pipelines to form an integrated irrigation and drainage network. This facilitates unified management during large-area slope restoration, improves restoration efficiency, and enhances the slope's erosion resistance through the overall layout, promoting the integrity and stability of ecological restoration.

[0028] Example 2: A greening and planting device for ecological restoration of mine slopes, referring to... Figure 1 , Figure 2 and Figure 3Based on the same concept as Embodiment 1 above, this embodiment proposes a support component 1 including a support frame 101 disposed below the composite planting component 2. The bottom surface of the support frame 101 is welded with evenly distributed anchor rods 102. The support frame 101 is disposed below the composite planting component 2 to provide it with stable support. The evenly distributed anchor rods 102 can penetrate into the surface of the slope, enhance the connection strength between the overall structure and the slope, reduce the risk of device slippage caused by steep slope or complex terrain, improve long-term stability, and adapt to the complex terrain of mine slopes. L-shaped connecting corner seats 213 are installed at the four corners of the water collection trough 205. The bottom end of the L-shaped connecting corner seats 213 is installed on the upper surface of the support frame 101. By adopting the above technical solution, the L-shaped connecting corner seats 213 rigidly connect the water collection trough 205 and the support frame 101, which can strengthen the integrity of the composite planting component 2 and the support component 1, reduce the relative loosening of the two under slope vibration or water flow impact, and further improve the structural stability of the device.

[0029] Reference Figure 2 , Figure 3 and Figure 4The water supply component 3 includes a water storage tank 301 fixedly connected to the upper surface of the support frame 101. A removable top cover 302 is installed on the top of the water storage tank 301. A filter screen 303 is installed on the inner wall of the water storage tank 301. The water storage tank 301 can store rainwater or external water sources, providing a stable water reserve for vegetation growth. The filter screen 303 can filter particles such as sediment in the water, preventing clogging and ensuring smooth water supply, adapting to the complex water quality environment of mines. The removable top cover 302 allows for convenient regular cleaning and maintenance of the filter screen 303. A first submersible pump 304 is installed on the inner bottom wall of the water storage tank 301. The output end of the first submersible pump 304 is connected to a water suction pipe 305. The output end of the water suction pipe 305 is connected to one of two water inlets 209. The first submersible pump 304 can stably deliver water from the water storage tank 301 to the water inlet 209 through the water suction pipe 305, and then distribute it evenly through the drip irrigation pipe 210. The water supply is automatically adjusted to the planting soil 208, reducing reliance on manual irrigation. This is especially suitable for long-term maintenance of slopes in remote mines. A second submersible pump 306 is installed on the inner top wall of the top cover 302. The top of the second submersible pump 306 is connected to a water pipe 307. The input end of the water pipe 307 is connected to one of the two drain outlets 211. The second submersible pump 306 can pump excess water discharged from the water collection tank 205 through the drain outlet 211 back to the water storage tank 301 through the water pipe 307, realizing water resource recycling, saving irrigation water, and enhancing the applicability of the device in arid or water-scarce environments. The bottom of the water storage tank 301 is connected to a drain outlet 309, and the top of the top cover 302 is equipped with a replenishment outlet 308. The output end of the replenishment outlet 308 is connected to the inside of the water storage tank 301. The replenishment outlet 308 and the drain outlet 309 facilitate the replenishment and discharge of liquid inside the water storage tank 301, making it more practical.

[0030] The implementation principle of this application embodiment is as follows: First, the anchor rod 102 in the support component 1 penetrates into the surface of the slope to form a stable foundation with the support frame 101. Then, the composite planting component 2 is rigidly connected to the support frame 101 with the help of the L-shaped connecting corner bracket 213 to ensure the stable installation of the overall structure on the slope. Inside the composite planting component 2, the planting soil 208 is used for planting vegetation. The slow-release fertilizer layer 207 below it slowly releases nutrients, and the water-retaining layer 206 retains moisture, together providing continuous growth conditions for the vegetation. The hollow buffer layer 203 between the rigid protective shell 201 and the permeable bearing layer 202 can buffer the impact of rainwater or irrigation water, reducing the direct scouring of the planting soil 208 by the water flow. Excess water flows into the water collection tank 205 through the drainage hole 204, and is then discharged or recycled through the drainage outlet 211. In the water supply component 3, the water storage tank 301 is replenished with water through the replenishment port 308 on the top cover 302. After the filter screen 303 filters impurities, the first submersible pump 304 delivers water through the pumping pipe 305 and the inlet 209 to the drip irrigation pipe 210 for precise irrigation of the planting soil 208. If there is excess water in the collection trough 205, the second submersible pump 306 pumps the water back to the water storage tank 301 through the delivery pipe 307 for recycling, avoiding water waste. The biodegradable protective net 212 initially covers the top of the rigid protective shell 201, preventing the planting soil 208 particles from being lost with the water flow. It degrades naturally over time without affecting the vegetation growth space. When large-scale restoration is required, multiple sets of composite planting components 2 are connected through pipelines via the inlet 209 and the outlet 211 to form an integrated irrigation and drainage network. This network coordinates water resources and works synergistically to prevent erosion, retain water and fertilizer, and promote growth, ultimately achieving ecological restoration of the mine slope.
