Description

Technical Field

[0001] This utility model relates to the field of slope ecological restoration technology, specifically to a mine slope ecological restoration system with water storage and irrigation functions. Background Technology

[0002] During mining operations, the original environment is damaged, resulting in large areas of exposed slopes. These slopes are highly susceptible to soil erosion under the influence of rainwater, and can even lead to geotechnical engineering disasters. Mining companies need to implement soil and water conservation measures to prevent soil erosion and restore the damaged soil and water environment. Ecological restoration of mine slopes is characterized by large implementation areas and high water consumption for vegetation maintenance. However, due to climatic reasons, there is a significant difference in rainfall between the rainy and dry seasons in some areas. During the rainy season, rainwater is discharged, resulting in waste, while the dry season sees prolonged periods without rainfall, causing water shortages. During the dry season, aside from water for daily production, there is almost no water for vegetation maintenance, leading to soil cracking, increased susceptibility to windblown sand, withered vegetation, and poor ecological restoration results.

[0003] In existing technologies, ecological restoration of mine slopes generally involves covering the slope with soil, planting greenery, and establishing a drip irrigation system. However, this approach has the following shortcomings: 1) Simple soil covering and planting greenery are insufficient to retain water in the initial stages due to the weak root systems of the greenery. The greenery is easily washed away by rainwater, resulting in a low survival rate. 2) Drip irrigation systems require external water sources. During severe droughts, companies often stop watering for greening to ensure production water supply. 3) Drip irrigation systems spray water onto the slope surface. In summer, due to high temperatures, water evaporates easily, and the roots and stems of the greenery absorb little water, resulting in poor water replenishment.

[0004] In conclusion, there is an urgent need for an ecological restoration system for mine slopes that has water storage and irrigation functions to solve the problems existing in current technologies. Utility Model Content

[0005] The purpose of this utility model is to provide a mine slope ecological restoration system with water storage and irrigation functions, aiming to solve the problems of water shortage in the dry season, low water absorption by plant roots and stems, and low survival rate in existing mine slope ecological restoration methods. The specific technical solution is as follows:

[0006] An ecological restoration system for mine slopes with water storage and irrigation functions is disclosed. The slopes are arranged in steps and the surface of the slopes is covered with a slope reclamation layer. A platform is provided between two adjacent slope levels. A drainage ditch is provided on the platform and the drainage ditch is located at the toe of the upper slope. A water storage tank is provided below the drainage ditch. Multiple water storage tanks are spaced apart along the length of the drainage ditch. The water storage tanks are connected to drainage pipes. The outlet end of the drainage pipe extends into the slope reclamation layer of the lower slope. A gate assembly is provided between the drainage pipe and the water storage tank.

[0007] Preferably, a filter layer is provided between the drainage ditch and the water storage tank.

[0008] Preferably, the filter layer includes a first crushed stone layer, a coarse sand layer, a second crushed stone layer, a first geotextile layer, and a steel grid layer arranged sequentially from top to bottom.

[0009] Preferably, the slope reclamation layer includes a bottom cover layer, a mac bedding layer, a top cover layer, and vegetation arranged sequentially from bottom to top, and the outlet end of the drainage pipe extends into the top cover layer.

[0010] Preferably, the outlet end of the drainage pipe is provided with a permeable hole at the bottom, and the outlet end of the drainage pipe is wrapped with a second geotextile layer, which covers the permeable hole and the outlet of the drainage pipe.

[0011] Preferably, the interval between two adjacent water storage tanks is 10-30 meters.

[0012] Preferably, the gate assembly includes a baffle plate, a connecting rod, and a screw rod. The lower end of the connecting rod is provided with a baffle plate, and the baffle plate is located at the gate between the drainage pipe and the water storage tank. The upper connecting end of the connecting rod is threadedly connected to the screw rod, and rotating the screw rod enables the baffle plate to move up and down.

[0013] Preferably, the gate assembly includes a baffle plate, a connecting rod, a screw rod, and an adjusting nut. The lower end of the connecting rod is provided with a baffle plate, which is located at the gate between the drainage pipe and the water storage tank. The upper connecting end of the connecting rod is movably sleeved on the screw rod, and the adjusting nut is provided on the screw rod and located below the connecting end.

[0014] The application of the technical solution of this utility model has the following beneficial effects:

[0015] In the ecological restoration system for mine slopes of this utility model, the gate assembly is closed to cut off the drainage pipe from the water storage tank, and the rainwater during the rainy season can be stored in the water storage tank; during the dry season, the gate assembly is opened, and the rainwater stored in the water storage tank can be used to irrigate the slope reclamation layer, effectively solving the problem of water shortage during the dry season.

[0016] By extending the drainage pipes into the top cover layer, irrigation can be directly applied to the roots of the plants, reducing evaporation during the dry season and increasing root absorption. The mac mat reduces the dynamic impact of rainwater and wind on the soil, slows surface water flow, thus preventing soil erosion, promoting seed germination, strengthening root systems, and permanently reinforcing the soil. Both the bottom and top cover layers provide essential nutrients and a foundation for plant growth.

[0017] This utility model of an ecological restoration system for mine slopes can effectively enhance the role of vegetation in soil stabilization and water retention, thereby improving the ecological restoration effect.

[0026] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] Example:

[0029] See Figures 1-5 This embodiment provides a mine slope ecological restoration system with water storage and irrigation functions. The slope 1 is arranged in steps and the surface of the slope 1 is provided with a slope reclamation layer 3. A platform 2 is provided between two adjacent slopes 1. A drainage ditch 4 is provided on the platform 2 and the drainage ditch 4 is located at the toe of the upper slope 1. A water storage tank 6 is provided below the drainage ditch 4. Multiple water storage tanks 6 are arranged at intervals along the length of the drainage ditch 4. The water storage tank 6 is connected to a drainage pipe 8. The outlet end of the drainage pipe 8 extends into the slope reclamation layer 3 of the lower slope 1. A gate assembly 7 is provided between the drainage pipe 8 and the water storage tank 6.

[0030] In the mine slope ecological restoration system of this embodiment, the gate assembly is closed to cut off the connection between the drainage pipe 8 and the water storage tank 6. Rainfall during the rainy season can be stored in the water storage tank 6. During the dry season, the gate assembly is opened, and the rainwater stored in the water storage tank 6 can be used to irrigate the slope reclamation layer, effectively solving the problem of water shortage during the dry season.

[0031] Preferably, in this embodiment, the interval between two adjacent water storage tanks 6 is 10-30 meters. The water storage tanks serve to store rainwater during the rainy season. The capacity, number, and spacing of the water storage tanks can be adjusted according to the actual situation. At the same time, a single water storage tank 6 can also be connected to multiple drainage pipes 8, and the outlet end of each drainage pipe 8 can be set at different heights to expand the irrigation range of a single water storage tank.

[0032] like Figure 1 As shown, in this embodiment, a filter layer 5 is provided between the drainage ditch 4 and the water storage tank 6. The filter layer 5 can filter out particulate matter (such as silt and other impurities) in the rainwater, preventing particulate matter from accumulating at the bottom of the water storage tank, reducing its capacity, and clogging the drainage pipe 8. Figure 2As shown, the filter layer 5 includes, from top to bottom, a first crushed stone layer 5.1, a coarse sand layer 5.2, a second crushed stone layer 5.3, a first geotextile layer 5.4, and a steel grid layer 5.5. The steel grid layer 5.5 is the load-bearing structure of the entire filter layer 5, ensuring that the entire filter layer 5 can be well set between the drainage ditch and the water storage tank without collapsing. The first crushed stone layer 5.1, the coarse sand layer 5.2, the second crushed stone layer 5.3, and the first geotextile layer 5.4 are used to filter the rainwater entering the water storage tank from the drainage ditch layer by layer, preventing particulate matter from entering the water storage tank with the rainwater.

[0033] like Figure 3 As shown, the slope reclamation layer 3 includes, from bottom to top, a bottom topsoil layer 3.1, a mac mat layer 3.2, a top topsoil layer 3.3, and vegetation 3.4. The outlet end of the drainage pipe 8 extends into the top topsoil layer 3.3. By extending the drainage pipe 8 into the top topsoil layer 3.3, irrigation can be directly applied to the roots of the vegetation, reducing evaporation of irrigation water during the dry season and increasing the absorption rate of the vegetation roots. The mac mat can reduce the dynamic impact of rainwater and wind on the soil, reduce the surface water flow velocity, and achieve the goals of preventing soil erosion, promoting seed germination, strengthening plant roots, and permanently reinforcing the soil. The bottom and top topsoil layers provide basic nutrients and a foundation for the growth of the vegetation.

[0034] like Figure 5 As shown, the outlet end of the drainage pipe 8 has a permeable hole 8.1 at the bottom. The outlet end of the drainage pipe 8 is wrapped with a second geotextile layer 9, which covers the permeable hole 8.1 and the outlet of the drainage pipe 8. Covering the permeable hole 8.1 and the outlet of the drainage pipe with the second geotextile layer 9 allows for irrigation of the slope reclamation layer 3 at a slower seepage rate at the outlet end. At the same time, the second geotextile layer 9 also prevents sand and gravel from clogging the permeable hole and the outlet of the drainage pipe.

[0035] like Figure 4 As shown, the gate assembly 7 in this embodiment includes a baffle plate 7.1, a connecting rod 7.2, a screw rod 7.3, and an adjusting nut 7.4. The lower end of the connecting rod 7.2 is provided with the baffle plate 7.1, which is located at the gate between the drainage pipe 8 and the water storage tank 6. The upper connecting end of the connecting rod 7.2 has a through hole and is movably sleeved on the screw rod 7.3 through the through hole. The adjusting nut 7.4 is located on the screw rod 7.3 and below the connecting end. Tightening the adjusting nut causes it to move up and down, thereby moving the baffle plate up and down. With this structural configuration, the descent of the baffle plate depends on its own gravity, and the screw rod can be fixed in this configuration.

[0036] Preferably, in some embodiments, the gate assembly 7 may include a baffle plate 7.1, a connecting rod 7.2, and a screw 7.3. The lower end of the connecting rod 7.2 is provided with the baffle plate 7.1, and the baffle plate is located at the gate between the drainage pipe 8 and the water storage tank 6. The upper connecting end of the connecting rod 7.2 is provided with a threaded hole and is threadedly connected to the screw 7.3 through the threaded hole. Rotating the screw 7.3 causes the baffle plate 7.1 to move up and down, thereby controlling the opening and closing of the gate. In this structural configuration, the screw 7.3 needs to be configured as a rotatable structure, for example, the lower end of the screw is installed through a bearing or other components to achieve the effect of screw rotation.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
