Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slope ecological restoration, in particular to a mine ecological restoration system. BACKGROUND

[0002] The slope formed after mining usually has problems such as single vegetation community, serious soil erosion, and poor landscape effect, which together lead to extremely fragile ecological environment in the region where the mine is located. These regions often suffer from severe soil erosion, and the natural recovery process is very slow. Therefore, vegetation restoration of mine slope has become a key task in the field of ecological restoration.

[0003] In the already closed open-pit mine area, bare slopes can often be observed, which contain soil and can provide certain conditions for plant growth. However, the mine slope itself is steep, and it is difficult for the soil to cohere into a certain thickness on the slope body, and the soil on the surface of the slope body is easily washed away by rainwater, at the same time, the newly planted ecological restoration plants mainly rely on artificial water and fertilizer management in the early stage, which requires a large amount of labor.

[0004] Chinese patent document CN202221946483.0 discloses a slope reinforcing geogrid for water storage irrigation of plants, which can block part of the downward infiltration of water through the setting of a baffle, store water for the vegetation on the slope, and increase the water storage capacity through the multiple water storage holes opened on the upper surface of the baffle, which is conducive to the growth of the vegetation on the slope, and at the same time, the rainwater is retained through the setting of a water storage tank, and the water in the water storage tank can provide water when the soil on the top of the slope is lacking in water, and the cotton sheet can absorb the water in the water storage tank to the top layer of soil, which is conducive to the growth of the vegetation. However, the baffle and the water storage tank need to be deeply buried, resulting in a large increase in additional construction amount during the ecological restoration process, and in addition, the efficiency of the cotton sheet in absorbing the water in the water storage tank to the top layer of soil for water replenishment based on the capillary phenomenon is low.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0017] 1. The mine ecological restoration system provided in this embodiment can stabilize the soil on the slope surface by setting up a planting module, providing soil for plant growth; and further stabilize the planting module by setting up a grid beam to prevent the overall collapse of the planting module; in addition, it can use hollow beams to collect and store rainwater and slowly seep out for a period of time after rain, so as to achieve the purpose of continuously supplying water to the ecological restoration plants planted in the planting module.

[0018] 2. The mine ecological restoration system provided in this embodiment can automatically open the seepage holes to replenish water to the ecological restoration plants in the planting module or automatically block the seepage holes to cut off water replenishment based on historical and future weather information, thereby reducing the manpower required to maintain the ecological restoration plants on the mine slope; in another irrigation module implementation, the mine ecological restoration system can automatically control the opening and closing of the T-shaped three-way pipe based on the state change of the second filler when it absorbs water and expands and loses water and shrinks, thereby realizing adaptive emergency irrigation based on soil moisture;

[0019] 3. The mine ecological restoration system provided in this embodiment includes a fertilization module. As water flows out of the crossbeam through the seepage holes, the water level in the crossbeam gradually decreases. This causes the float to slide down the chute under the action of the elastic potential energy gradually released by the elastic bladder and the weight of the slider itself. Liquid concentrated fertilizer or nutrient solution stored in the storage pipe is then drawn into the elastic bladder through the connecting pipe, and the amount drawn in is positively correlated with the change in the water level in the crossbeam. In the event of rainfall, rainwater collects and enters the crossbeam through the inlet hole, causing the water level in the crossbeam to rise. The float then floats upward along the chute, and the upward movement of the float causes the outlet pipe to press upward against the elastic bladder. During this compression, the liquid concentrated fertilizer or nutrient solution in the elastic bladder is squeezed out through the outlet pipe into the water body below, and the amount squeezed out is positively correlated with the change in the water level in the crossbeam. Therefore, the content of liquid concentrated fertilizer or nutrient solution in the water body of the crossbeam remains essentially constant, which is beneficial for replenishing the growth needs of the ecological restoration plants in the planting module.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments and accompanying drawings. The illustrative embodiments and descriptions of this invention are for illustrative purposes only and are not intended to limit the invention. It should be noted that this invention is already in the actual research and development stage.

[0032] Slopes formed after mining operations typically suffer from problems such as monotonous vegetation communities, severe soil erosion, and poor landform aesthetics. These issues collectively contribute to the extreme fragility of the ecological environment in mining areas. These areas often experience severe soil erosion, and the natural recovery process is extremely slow. Therefore, vegetation restoration of mining slopes has become a crucial task in the field of ecological restoration.

[0033] In closed open-pit mine areas, exposed slopes are often observed. Although these slopes contain soil, which can provide some conditions for plant growth, the slopes themselves are quite steep, making it difficult for the soil to adhere to a certain thickness. Furthermore, the soil on the slope surface is easily washed away by rainwater. In addition, newly planted ecological restoration plants initially rely heavily on manual water and fertilizer management, resulting in a large labor input.

[0034] Chinese patent document CN202221946483.0 discloses a slope reinforcement geogrid for water storage and irrigation of vegetation. It uses baffles to block some of the downward seepage of water, storing water for the vegetation on the slope. Multiple water-storing holes on the upper surface of the baffles increase the water storage capacity, promoting vegetation growth. Simultaneously, a water tank retains rainwater, providing moisture when the top soil of the slope is dry. Cotton pads absorb the water from the tanks and transfer it to the top soil, further benefiting vegetation growth. However, the baffles and water tanks require deep burial, significantly increasing the additional construction work required for ecological restoration. Furthermore, the efficiency of using capillary action to absorb water from the tanks and transfer it to the top soil for irrigation is relatively low.

[0035] To address this, the present invention provides a mine ecological restoration system. By setting up planting modules, the soil on the slope surface can be stabilized to provide the soil needed for plant growth. Furthermore, by setting up grid beams, the planting modules are further stabilized to prevent the overall collapse of the planting modules. In addition, the crossbeams of the grid beams can collect and store rainwater and slowly seep out over a period of time after rain, so as to achieve the purpose of continuously supplying water to the ecological restoration plants planted in the planting modules.

[0036] Example 1:

[0037] like Figure 1As shown, this embodiment provides a mine ecological restoration system, which includes: a lattice beam and a planting module 2;

[0038] The lattice beam includes a horizontal beam 11 and a longitudinal beam 12;

[0039] The crossbeam 11 is a hollow beam, with a water inlet hole 111 on the side of the crossbeam 11 facing the top of the slope and an outlet hole 112 on the side facing the bottom of the slope.

[0040] The planting module 2 is set in the grid formed by the lattice beam, and the planting module 2 is used to plant ecological restoration plants.

[0041] It should be understood that the cross-sectional area of ​​the water inlet 111 is relatively large, allowing the crossbeam 11 to collect as much rainwater as possible during rainfall at the mine location; while the cross-sectional area of ​​the seepage hole 112 is relatively small, allowing water to seep out of the crossbeam 11 slowly. This prolongs the time the crossbeam 11 can supply water to the ecological restoration plants, and also avoids root rot caused by excessive watering in a short period. Preferably, the water inlet 111 is an elongated hole with its length parallel to the length direction of the crossbeam 11. A filter screen is installed on the outside of the water inlet 111, thereby ensuring the water collection effect of the crossbeam 11 while preventing soil and gravel from entering the internal cavity of the crossbeam 11.

[0042] Specifically, such as Figures 1 to 4 As shown, the planting module 2 is selected from one or more of the geocell 21 and the concrete frame 22.

[0043] A first permeable hole 211 is provided at the node of the geocell 21 along the thickness direction of the node, and when the geocell 21 is laid on the slope of the mine, the first permeable hole 211 faces the toe of the slope.

[0044] The concrete frame 22 is a regular hexagonal concrete frame 22. A second permeable hole 221 is provided at one of the pointed corners of the concrete frame 22. When the concrete frame 22 is laid on the slope of the mine, the second permeable hole 221 faces the toe of the slope.

[0045] in, Figure 1 and Figure 2 The illustration schematically depicts a scenario where regular hexagonal concrete frames 22 are set up on a mine slope as planting modules 2. When using regular hexagonal concrete frames 22 as planting modules 2, it is preferable to... Figure 2The concrete cells are laid in the manner shown, with gaps between adjacent concrete cells 22. During rainfall, rainwater collected in the upper concrete cells 22 flows downward through the second permeable hole 221 and then flows downward through the gap to the lower crossbeam 11, where it is collected by the water inlet hole 111 of the crossbeam 11. Similarly, when the geocell 21 is used as the planting module 2, rainwater collected in each compartment of the geocell 21 flows into the lower compartment through the first permeable hole 211 until it reaches the lower crossbeam 11, where it is collected by the water inlet hole 111 of the crossbeam 11.

[0046] More preferably, the seepage holes 112 are filled with a first filler 113, the first filler 113 being selected from one or more of porous ceramic filter elements, polyurethane foam, and gravel;

[0047] A filter cover 114 is connected to one end of the seepage hole 112 located inside the crossbeam 11.

[0048] Accordingly, in this preferred embodiment, compared to opening or reserving a seepage hole 112 with a small cross-sectional area on the crossbeam 11, the cross-sectional area of ​​the seepage hole 112 itself can be larger, making it easier to open or reserve. By filling the seepage hole 112 with a first filler 113, the effective flow area of ​​the seepage hole 112 is reduced, thereby achieving the purpose of slow seepage. By connecting a filter cover 114 inside the seepage hole 112, the seepage hole 112 can be effectively prevented from being blocked and unable to seep water.

[0049] Accordingly, the mine ecological restoration system provided in this embodiment can stabilize the soil on the slope surface by setting up the planting module 2, providing the soil needed for plant growth; and further stabilize the planting module 2 by setting up grid beams to prevent the overall collapse of the planting module 2; in addition, it can also use the hollow crossbeam 11 to collect and store rainwater and slowly seep out for a period of time after rain, so as to achieve the purpose of continuously supplying water to the ecological restoration plants planted in the planting module 2.

[0050] Preferably, a water inlet hole is also provided on the upper part of the crossbeam 11 (the water inlet hole is not shown in the figure).

[0051] Furthermore, if there has been no rainfall in the area where the mine is located for a long period of time, and the rainwater stored in the crossbeam 11 has been exhausted, water can be replenished to the crossbeam 11 through the water replenishment hole by means of manual transportation (such as water truck transportation or pipeline), so that the crossbeam 11 can continue to slowly seep water through the seepage hole 112 to supply the ecological restoration plants.

[0052] Example 2:

[0053] like Figure 5 As shown, this embodiment is based on embodiment 1, the difference being that in this embodiment:

[0054] The mine ecological restoration system also includes an irrigation module, which includes a sealing plug 41, a sliding rod 42, a linear motor 43, an information acquisition unit, and a control terminal.

[0055] The linear motor 43 is fixedly connected to the lattice beam, the slide rod 42 passes through the filter cover 114 and is slidably connected to the filter cover 114, the sealing plug 41 is fixedly connected to one end of the slide rod 42 located inside the filter cover 114 and seals the seepage hole 112, and the other end of the slide rod 42 extends to the outside of the crossbeam 11 and is fixedly connected to the output end of the linear motor 43.

[0056] Both the linear motor 43 and the information acquisition unit are electrically connected to the control terminal;

[0057] The information acquisition unit is able to obtain historical and future weather information for the location of the mine;

[0058] The control terminal responds to the historical and future weather information fed back by the information acquisition unit, and controls the linear motor 43 to retract so that the sealing plug 41 separates from the seepage hole 112.

[0059] It should be understood that the sealing plug 41 is made of flexible materials, such as rubber or silicone, which can reliably seal the seepage hole 112; the historical weather information acquired by the information acquisition unit may be, for example, the monitoring results measured and recorded by temperature monitoring equipment and rainfall monitoring equipment (temperature monitoring equipment and rainfall monitoring equipment are existing mature equipment and will not be described in detail) installed at the mine location; future weather information may be, for example, the predicted rainfall and predicted temperature at the mine location predicted by the meteorological department; the control terminal may be, for example, a PLC.

[0060] Accordingly, by controlling the action of each linear motor 43, the slide bar 42 can be driven to slide relative to the filter cover 114, thereby causing the sealing plug 41 to block the seepage hole 112 or separate from the seepage hole 112, thereby controlling the timing of the release of rainwater stored in the crossbeam 11.

[0061] The mine ecological restoration system provided in this embodiment electrically connects the information acquisition unit and each linear motor 43 to the control terminal. Based on the historical and future weather information fed back by the information acquisition unit, the control terminal can automatically control the movement of the linear motors 43. This enables the mine ecological restoration system to automatically open the seepage holes 112 to replenish water to the ecological restoration plants in the planting module 2 or automatically block the seepage holes 112 to cut off water supply, thereby enabling the mine ecological restoration system to automatically irrigate the ecological restoration plants in the planting module 2 according to the weather, reducing the manpower required to maintain the ecological restoration plants on the mine slope.

[0062] More specifically, the historical weather information includes historical rainfall and historical temperature at the location of the mine, and the future weather information includes predicted rainfall and predicted temperature at the location of the mine.

[0063] like The control terminal controls the linear motor 43 to retract, causing the sealing plug 41 to separate from the seepage hole 112;

[0064] in, R p Indicates the past m The actual cumulative rainfall of the day, T i Indicates the past number i The actual highest temperature of the day T 0 Indicates the preset temperature. k Indicates the temperature coefficient. A This represents the first preset threshold. R f Indicates the future n The predicted cumulative rainfall for the day, T j Indicates the future number j The predicted highest temperature of the day, B This indicates the second preset threshold.

[0065] in, m The preferred value is 5-7. n The preferred value is 3-5. T 0 The preferred value is 33℃-35℃. k The preferred value is 0.35 mm / ℃ to 0.45 mm / ℃. A The preferred value is 10mm-20mm. B The preferred values ​​are 6mm-12mm. It should be understood that the values ​​of the above parameters need to be adjusted according to the drought resistance of the ecological restoration plants (mainly affected by variety and growth stage), soil characteristics, etc.

[0066] Based on this, the mine ecological restoration system provided in this embodiment extends the output end of the linear motor 43 through the control terminal, thereby keeping the seepage hole 112 normally closed. Then, the control terminal moves to the location of the mine. m Effective rainfall (past) m The actual cumulative rainfall of the day minus the past m The equivalent evaporation per day is less than the first preset threshold (i.e., the past...). m (insufficient rainfall), and in the future n Predicted effective rainfall (future) nThe predicted cumulative rainfall for the day minus the past n If the equivalent evaporation per day is less than the second threshold (i.e., in the future) n (If there is insufficient rainwater to replenish the plant), the output end of the linear motor 43 is retracted, thereby separating the sealing plug 41 from the seepage hole 112, and the irrigation operation for the ecological restoration plants begins. Preferably, after the control terminal controls the output end of the linear motor 43 to retract in the manner described above, it controls the output end of the linear motor 43 to extend after a preset time, thereby stopping the irrigation operation.

[0067] Therefore, the mine ecological restoration system provided in this embodiment can automatically start and stop emergency irrigation of ecological restoration plants based on the historical rainfall, historical temperature, predicted rainfall, and predicted temperature of the mine location, thereby helping newly planted ecological restoration plants to successfully survive the dry season without the need for manual intervention in irrigation.

[0068] Example 3:

[0069] like Figure 6 As shown, this embodiment is based on embodiment 1, the difference being that in this embodiment:

[0070] The mine ecological restoration system also includes an irrigation module, which includes a T-shaped tee pipe 51, a cylinder 52, a push plate 53, a push rod 54, a second filler 55, and a return spring 56.

[0071] The T-shaped tee pipe 51 is connected to one end of the seepage hole 112 located outside the crossbeam 11;

[0072] A plurality of third permeable holes are provided on the wall of the cylinder 52. The cylinder 52 is buried in the soil below the T-shaped tee pipe 51. The push plate 53 is slidably disposed inside the cylinder 52 along the axial direction of the cylinder 52.

[0073] The push plate 53 is fixedly connected to the push rod 54 on the side near the T-shaped three-way pipe 51. The end of the push rod 54 away from the push plate 53 passes through the end face of the cylinder 52 and is inserted into the T-shaped three-way pipe 51. The inner cavity of the cylinder 52 located on the other side of the push plate 53 is filled with a second filler 55.

[0074] The reset spring 56 is located on the side of the push plate 53 that connects to the push rod 54. One end of the reset spring 56 is connected to the push plate 53, and the other end is connected to the cylinder 52.

[0075] The second packing 55 can absorb water and expand to push the push plate 53 so that the push rod 54 is inserted into the T-shaped tee pipe 51. When the second packing 55 loses water and shrinks, the reset spring 56 can push the push plate 53 so that the push rod 54 is pulled out of the T-shaped tee pipe 51.

[0076] Based on this, in the mine ecological restoration system provided in this embodiment, when the soil around the cylinder 52 is dry, the second filler 55 in the cylinder 52 loses water and shrinks. Then, under the action of the return spring 56, the push plate 53 is pushed downward, causing the push rod 54 to be pulled out from the T-shaped three-way pipe 51. At this time, the water in the crossbeam 11 flows out through the T-shaped three-way pipe 51 to provide emergency irrigation for the ecological restoration plants. During the irrigation process, the water flowing out of the T-shaped three-way pipe 51 gradually seeps down and enters the cylinder 52 through the third water permeable hole (not shown in the figure), causing the second filler 55 to absorb water and expand. The expansion of the second filler 55 pushes the push plate 53 upward, and then the push rod 54 is inserted into the T-shaped three-way pipe 51. At this time, the water in the crossbeam 11 cannot flow out through the T-shaped three-way pipe 51, thus stopping the emergency irrigation for the ecological restoration plants.

[0077] Accordingly, the mine ecological restoration system provided in this embodiment can automatically control the opening and closing of the T-shaped three-way pipe 51 based on the state changes of the second filler 55 during water absorption and expansion and water loss and shrinkage, thereby realizing adaptive emergency irrigation based on soil moisture. It is especially suitable for areas with distinct rainy and dry seasons, ensuring that seedlings can successfully survive the dry season in the early stages of ecological restoration plant growth.

[0078] Specifically, the second filler 55 is selected from one or more of superabsorbent resin and bentonite;

[0079] The second filler 55 is contained in a dispensing bag, which is selected from one or more of PTFE microporous membrane, nylon 66 microporous membrane, PP microporous membrane and nonwoven fabric.

[0080] Therefore, the second packing material 55 can reliably cycle a large number of times, and when it absorbs water and expands, it has sufficient pushing force to allow the push rod 54 to be inserted into the T-shaped tee pipe 51, thereby sealing the T-shaped tee pipe 51 and cutting off the channel for water to flow out of the crossbeam 11. Using a packaging bag to hold the second packing material 55 can effectively prevent leakage.

[0081] Example 4:

[0082] like Figure 7 , Figure 8 As shown, this embodiment is based on embodiment 1, the difference being that in this embodiment:

[0083] The mine ecological restoration system also includes a fertilization module, which includes a storage pipe 31;

[0084] The storage tube 31 is installed at the top of the internal cavity of the crossbeam 11 along the length of the crossbeam 11;

[0085] At least one through hole is provided at the lower part of the storage tube 31.

[0086] Accordingly, the mine ecological restoration system provided in this embodiment can store a large amount of liquid concentrated fertilizer or nutrient solution at one time based on the storage pipe 31 (existing commercially available products can be selected according to the needs of the ecological restoration plants). After the fertilizer is replenished, these liquid concentrated fertilizers or nutrient solutions can be slowly released into the water body below. Then, the water body mixed with liquid concentrated fertilizers or nutrient solutions is used to irrigate the ecological restoration plants in the planting module 2, which is conducive to providing sufficient nutrients for the growth of the ecological restoration plants.

[0087] However, in the above implementation plan, due to the uncertainty of rainfall, the concentration of liquid concentrated fertilizer or nutrient solution in the water of the crossbeam 11 is likely to increase (i.e., there is no rainfall for a long time, and the water in the crossbeam 11 becomes less and less while the liquid concentrated fertilizer or nutrient solution continues to mix in), which poses a risk of burning the seedlings.

[0088] Therefore, based on the above implementation scheme, the fertilization module also includes a connecting pipe 32, an elastic bladder 33, an outlet pipe 34, a guide pipe 35, and a float 36;

[0089] The connecting pipe 32 is connected below the through hole, and a first one-way valve that leads downward is installed inside the connecting pipe 32 (the first one-way valve is not shown in the figure).

[0090] The elastic bladder 33 is connected below the connecting tube 32, and the outlet tube 34 is connected below the elastic bladder 33. A downward-directing second one-way valve (not shown in the figure) is installed in the outlet tube 34.

[0091] The guide tube 35 is fixedly installed inside the crossbeam 11. The guide tube 35 is vertical and sleeved on the outside of the elastic bladder 33. An axial groove 351 is formed on the peripheral wall of the guide tube 35, and the groove 351 penetrates the peripheral wall of the guide tube 35.

[0092] The outlet pipe 34 is fixedly connected to the float 36, and the float 36 is slidably connected to the guide pipe 35 through the slide groove 351.

[0093] Therefore, as the water in the crossbeam 11 flows out through the seepage hole 112, the water level in the crossbeam 11 gradually decreases (from... Figure 7 Change to Figure 8As shown in the diagram, the float 36 slides down the slide groove 351 under the action of the elastic potential energy gradually released by the elastic bladder 33 and the weight of the slider itself. The liquid concentrated fertilizer or nutrient solution stored in the storage pipe 31 is then drawn into the elastic bladder 33 via the connecting pipe 32 (due to the suction effect caused by the expansion of the elastic bladder 33). The amount drawn in is positively correlated with the change in liquid level in the crossbeam 11. In the event of rainfall, rainwater collects and enters the crossbeam 11 through the inlet hole 111, causing the water level in the crossbeam 11 to rise. This causes the float 36 to float upwards along the slide groove 351, and the upward movement of the float 36 drives the outlet pipe 34 towards... As the elastic bladder 33 is compressed and shortened axially, the liquid concentrated fertilizer or nutrient solution in the elastic bladder 33 is squeezed out into the water below through the outlet pipe 34, and the amount squeezed out is positively correlated with the change in liquid level in the crossbeam 11. As a result, the content of liquid concentrated fertilizer or nutrient solution in the water in the crossbeam 11 remains basically constant, which is beneficial to replenishing the growth needs of the ecological restoration plants in the planting module 2. By setting the guide pipe 35, the upward floating path of the float 36 can be constrained, and the elastic bladder 33 can be constrained to only expand and contract in the vertical direction, preventing it from folding or bending laterally.

[0094] Accordingly, the mine ecological restoration system provided in this embodiment, by setting up the above-mentioned fertilization module, can promptly mix the corresponding amount of liquid concentrated fertilizer or nutrient solution into the water body newly entering the crossbeam 11 during rainfall, thereby making the content of liquid concentrated fertilizer or nutrient solution in the water body in the crossbeam 11 basically stable, thus ensuring the growth needs of the ecological restoration plants in the planting module 2.

[0095] It should be understood that a supplementary tube (not shown in the figure) extending to the outside of the crossbeam 11 is connected to the storage tube 31 for replenishing the storage tube 31 with liquid concentrated fertilizer or nutrient solution, and the supplementary tube can be used to balance the air pressure when the elastic bladder 33 extends to draw liquid concentrated fertilizer or nutrient solution from the storage tube 31.

[0096] Preferably, the elastic bladder 33 has a bellows structure and its axis is vertical. Specifically, the elastic bladder 33 is made as follows: Figure 7 , Figure 8 The bellows structure shown allows the elastic bladder 33 to contract axially when the float 36 rises and causes the outlet pipe 34 to press upward against the elastic bladder 33. The elastic bladder 33 can be made of, for example, rubber.

[0097] In this application, the term "sliding connection" refers to a connection where two parts can only slide relative to each other, such as relative sliding defined by a groove.

It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
