Description

Technical Field

[0001] This utility model relates to the field of ecological technology for mine restoration, and in particular to a soil stabilization and drainage structure for mine ecological restoration. Background Technology

[0002] Mine ecological restoration is a crucial area for current environmental protection and sustainable resource utilization. With the large-scale exploitation of mineral resources, vegetation destruction, soil erosion, and frequent natural disasters such as landslides and debris flows on mine slopes pose serious threats to the ecological environment and human lives. Mine ecological restoration soil stabilization and drainage structures, as a novel slope management technology, aim to achieve the dual goals of slope stability and vegetation restoration through a combination of physical reinforcement and ecological restoration. Its applications cover mine slope management, ecological reconstruction of abandoned mining areas, and ecological restoration of steep rock slopes. With the deepening of the green development concept, the market demand for this technology in the field of mine ecological restoration continues to grow, demonstrating broad application prospects.

[0003] Existing mine ecological restoration technologies commonly include wire mesh covering, grass seeding, and simple vegetation planting. However, these technologies have many shortcomings in practical applications. For example, while wire mesh covering can prevent slope collapse in the short term, it cannot effectively solve the problem of secondary soil damage caused by rainwater erosion; grass seeding, due to the short development cycle of plant roots, is difficult to form a stable soil protective layer in the short term, especially during the rainy season, when the slope soil is still easily eroded.

[0004] Patent CN221721683U discloses a soil stabilization and drainage structure for ecological restoration in mines. This patent reinforces the slope using a U-shaped structure composed of vertical and horizontal beams, while drainage channels on the vertical beams direct rainwater from the top of the slope to the bottom, reducing erosion. Furthermore, plant seedlings within planting frames extend their roots from growth holes to the slope surface, further enhancing slope stability. However, this technology faces challenges at higher elevations. The limitations of capillary action hinder long-distance water transport, resulting in insufficient water supply to higher vegetation areas, thus affecting vegetation growth and restoration effectiveness, and limiting its application in the restoration of steep slopes.

[0005] Therefore, developing an ecological restoration technology that can adapt to steep slopes and achieve efficient water transport has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The present invention aims to provide a soil stabilization and drainage structure for mine ecological restoration to overcome the shortcomings mentioned above.

[0007] In order to achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A soil stabilization and drainage structure for mine ecological restoration includes:

[0009] Water collection troughs and confluence channels installed at the top and bottom of the slope, respectively; and

[0010] Multiple water intake channels are laid at an incline on the slope and used to connect the water collection channel and the confluence channel. Multiple planting areas are arranged in a matrix between adjacent water intake channels. Each planting area is equipped with a water storage mechanism. The water storage mechanisms located in the same incline direction are connected sequentially, and the uppermost and lowermost water storage mechanisms are connected to the water collection channel and the confluence channel one by one. The water storage mechanism is used to store water and transport it to the planting area.

[0011] Furthermore, the water storage mechanism includes:

[0012] A water storage tank is embedded in the slope. An inlet and a first outlet are provided on the upper side wall of the water storage tank. The outlet of the uppermost water storage tank is connected to the inlet of the lowermost water storage tank via a connecting pipe. The inlet of the uppermost water storage tank is connected to the water collection trough via the connecting pipe. The first outlet of the lowermost water storage tank is connected to the confluence channel via the connecting pipe.

[0013] One end is inserted into the water tank, and the other end is connected to the capillary tube in the planting area.

[0014] Further, the capillary includes:

[0015] One end is inserted into a water storage tank, and the other end is connected to a delivery pipe in the planting area. The other end of the delivery pipe is equipped with multiple water-permeable holes.

[0016] Absorbent cotton thread threaded inside the delivery pipe.

[0017] Furthermore, the top of the water storage tank is detachably connected to a tank cover, and one end of the delivery pipe and the absorbent cotton thread passes through the tank cover.

[0018] Furthermore, the capillary tube also includes filter cotton installed at the water-permeable hole.

[0019] Furthermore, it also includes planting frames installed one-to-one above the delivery pipe, with a number of growth holes running through the planting frames.

[0020] Furthermore, anchor rods are inserted at the corners of the planting frame, and the planting frame is fixedly installed on the slope by the anchor rods.

[0021] Furthermore, a sieve plate is provided at the upper end of the water collection tank, and a second water outlet and a third water outlet are provided on the side wall of the water collection tank. The second water outlet is located above the third water outlet. The second water outlet is connected to the input end of the water inlet trough, and the third water outlet is connected to the water inlet of the uppermost water storage tank through the connecting pipe.

[0022] Furthermore, the water collection tank is also equipped with an inclined filter plate, which is located above the third water outlet and slopes towards the second water outlet.

[0023] Compared with the prior art, this utility model has at least the following advantages:

[0024] To address the problem that capillary action in existing technologies is insufficient for long-distance water transport, this invention utilizes a layer-by-layer interconnected design for the water storage mechanism, enabling graded storage and layer-by-layer water transport. The connecting pipes between the water tanks transfer water layer by layer from the top of the slope to the bottom, ensuring a stable water supply for plants in all planting areas on steep slopes and solving the problem of water shortage for vegetation at higher elevations in existing technologies.

[0032] 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.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figure 1-2 This utility model provides a soil stabilization and drainage structure for mine ecological restoration, including a water collection trough 1, a confluence channel 2, a water diversion trough 3, a planting area and a water storage mechanism. Through scientific layout and functional synergy, it achieves the comprehensive effects of rainwater collection, storage, transportation and soil stabilization by plants.

[0035] Specifically, a water collection trough 1 is installed at the top of the slope to collect rainwater. A sieve plate 16 is installed at the upper end of the water collection trough 1 to filter debris and prevent clogging. The sidewalls of the water collection trough 1 are provided with a second and a third water outlet, with the second outlet located above the third outlet, for connecting the water intake trough 3 and the water storage mechanism, respectively. A confluence channel 2 is provided at the bottom of the slope to collect rainwater flowing down from the top and surface of the slope and guide it to a designated area, such as a water storage tank or drainage system. Multiple water intake troughs 3 are provided and laid at an angle on the slope. The water intake troughs 3 connect the water collection trough 1 at the top of the slope and the confluence channel 2 at the bottom of the slope to guide rainwater from the top of the slope to the bottom. Located on the slope, multiple planting areas are arranged in a matrix between adjacent water diversion channels 3. Each planting area is equipped with a water storage mechanism. The water storage mechanisms located in the same inclined direction are connected in sequence, and the uppermost and lowermost water storage mechanisms are connected to the water collection channel 1 and the confluence channel 2 one by one. The water storage mechanism is used to store water and transport it to the planting area.

[0036] Optionally, the water collection tank 1 is also provided with an inclined filter plate 19, which is located above the third outlet 18 and slopes towards the second outlet 17.

[0037] Combined with reference Figure 4-5The water storage mechanism includes a water tank 4 and capillary tubes. The water tank 4 is embedded in the slope. An inlet 5 and a first outlet 6 are located on the upper side wall of the water tank 4. The outlet of the upper-level water tank 4 is connected to the inlet 5 of the lower-level water tank 4 via a connecting pipe 7. The inlet 5 of the uppermost water tank 4 is connected to a collection trough 1 via a connecting pipe 7, and the first outlet 6 of the lowermost water tank 4 is connected to a confluence channel 2 via a connecting pipe 7. One end of the capillary tube is inserted into the water tank 4, and the other end is connected to the planting area, transporting water to the area around the plant roots through capillary action. A detachable cover 11 is attached to the top of the water tank 4 for easy regular inspection and maintenance. Simultaneously, the tiered design of the water storage mechanism reduces dependence on additional water sources, further lowering the economic cost of ecological restoration.

[0038] During the rainy season, rainwater from the top of the slope is filtered by the screen plate 16 of the collection trough 1 before entering the collection trough 1. Within the collection trough 1, some rainwater flows into the diversion channel 3 through the second outlet 17, flowing down the slope to the confluence channel 2 at the bottom; the remaining rainwater flows into the uppermost storage tank 4 through the third outlet 18. The water in the storage tank 4 is then sequentially transported to the next storage tank 4 via the connecting pipe 7, ultimately flowing into the confluence channel 2, achieving graded collection and transportation of rainwater. The filter plate 19 is designed to be inclined, allowing larger particles to flow out through the second outlet 17 under the wash of rainwater, reducing the possibility of clogging. Rainwater filtered by the filter plate 19 carries less sediment, further reducing the likelihood of clogging the connecting pipe 7.

[0039] This utility model utilizes the synergistic effect of the water collection trough 1, the water diversion trough 3, and the water storage mechanism to achieve efficient collection and graded transportation of rainwater, reduce the scouring force of rainwater on the slope, and reduce the risk of soil erosion.

[0040] Preferably, the capillary includes a delivery pipe 8, one end of which is inserted into the water storage tank 4, and the other end is connected to the planting area. This end has multiple permeable holes 9 for delivering water from the water storage tank 4 to the soil in the planting area. A water-absorbing cotton thread 10 is threaded through the delivery pipe 8, one end of which is inserted into the water storage tank 4, and the other end extends into the soil in the planting area, providing moisture to the plant roots through capillary action. This stable water supply mechanism can significantly improve the survival rate and growth rate of plants, accelerate the restoration of slope vegetation, and thus enhance the overall effect of mine ecological restoration. Filter cotton 12 is installed at the permeable holes 9 to prevent soil particles from entering the delivery pipe 8 and causing blockage. Water from the water storage tank 4 is delivered to the soil in the planting area through the water-absorbing cotton thread 10 and the permeable holes 9 of the capillary, providing stable moisture for the plants. During the dry season, water from the water storage tank 4 is continuously supplied through capillary action, ensuring the survival rate and growth rate of the plants.

[0041] Combined with reference Figure 3A planting frame 13 is installed above the corresponding delivery pipe 8 in each planting area. Several growth holes 14 are provided inside the frame to allow plant roots to grow and extend. Anchor rods 15 are inserted at the corners of the planting frame 13 to fix it to the slope and ensure the stability of the planting frame 13.

[0042] The planting frame 13 is made of biodegradable material and contains planted plants. The plant roots extend into the slope soil through growth holes, working together with the water storage mechanism and capillaries to further enhance the stability of the slope. The matrix-distributed water storage mechanism and planting frame design, combined with the fixing effect of the anchor rods 15, ensure the stability of the entire structure on steep slopes and effectively resist rainwater erosion and slope sliding.

[0043] Scientific water management and planting methods can quickly restore vegetation cover on mine slopes by 20%, improve the ecological environment, and reduce the probability of natural disasters.
