Description

Technical Field

[0001] This invention relates to the field of mine restoration technology, and more specifically, to a mine soil ecological restoration device. Background Technology

[0002] Heavy metal pollution in soil is one of the most prominent environmental hazards during mining operations. It is characterized by its insidious, long-term, and irreversible nature. It not only damages the physical and chemical properties of soil and leads to soil degradation, but also pollutes surrounding water bodies through surface runoff and rainwater leaching. This can directly poison vegetation or threaten human health through bioaccumulation in the food chain, posing a dual threat to both the ecosystem and human survival.

[0003] Among the remediation technologies for heavy metal contaminated soil, chemical remediation is the most widely used method. Its core is to add soil conditioners to reduce the bioavailability of heavy metals through adsorption, oxidation-reduction, antagonism, or precipitation. This technology has the advantages of in-situ operation, simple process, high construction efficiency, and controllable cost, making it very suitable for the actual needs of large-scale mine remediation.

[0004] However, most mining areas still use traditional chemical remediation methods, such as direct spraying or drilling injection of amendments. The migration of the amendments relies entirely on natural leaching and gravity infiltration. Due to the lack of effective artificial guidance and controlled release mechanisms, the amendments are prone to rapid loss along the preferential flow path in heterogeneous soil media, making it difficult to fully contact and react with soil particles. This results in low passivation efficiency of heavy metals and extremely unstable remediation effects. This problem is particularly prominent in mine slope remediation. Since slopes are mostly bare and steep, and it is difficult for imported soil to adhere, the current spraying method not only easily causes soil loss and prevents seeds from taking root, but also the amendment solution is mainly lost downhill due to gravity, making it difficult to effectively remediate uphill. This results in limited remediation range, uneven overall remediation effect, and difficulty in achieving long-term ecological restoration goals.

[0005] Therefore, this application proposes a mine soil ecological restoration device to solve the above problems. Summary of the Invention

[0010] In a new embodiment, the vertical strips of the reinforcing mesh are provided with concave arc grooves; the tops of the anchoring cylinder and the permeable core column are matched with the curvature of the concave arc grooves, which are used to guide rainwater or external water sources into the anchoring cylinder.

[0011] In a new embodiment, the guiding leakage assembly includes: a bottom sleeve threadedly installed at the bottom of the anchoring cylinder; an internal cavity formed in the middle of the bottom sleeve; a conical platform installed at the bottom of the internal cavity, and a partition plate installed at the middle of the top of the conical platform, the partition plate dividing the internal cavity into a downslope chamber and an upslope chamber; a downslope drainage ring disposed on the outer wall of the downslope chamber and facing the downslope direction; and an upslope drainage ring disposed on the outer wall of the upslope chamber and facing the upslope direction.

[0012] In a new embodiment, the slope-downward drainage ring is provided with a plurality of inclined drainage outlets at equal intervals; the slope-upward drainage ring is provided with a plurality of straight drainage outlets at equal intervals; and the inclined drainage outlets and straight drainage outlets are all filled with a slow-release filler.

[0013] In a new embodiment, grooves are provided on both sides of the partition plate, and a liquid-permeable filling plate is slidably installed in the grooves, the liquid-permeable filling plate being filled with an auxiliary repair medium.

[0014] In a new embodiment, a bottom cone is installed at the bottom end of the bottom sleeve, and a plurality of fixed inclined blocks are installed in a ring at equal intervals around the bottom cone.

[0016] In a new embodiment, the moisture equalization disc is a flat disc body, and the interior of the moisture equalization disc is filled with guide fibers; the guide fibers are hydrophilic fiber bundles that evenly distribute the water flow entering from the permeable core column to the entire bottom surface of the moisture equalization disc.

[0017] Beneficial effects: Compared with the prior art, the advantages of the present invention are: 1. The present application integrates the surface repair layer and the inner expansion repair components through the grid layout of reinforced hard mesh and anchoring cylinders, forming a three-dimensional repair network that links the points to the surface and the inside and outside, which solves the problems of easy loss of repair agent and disconnection between surface and inner repair in the existing slope repair technology, and realizes efficient and balanced repair of mine slope soil.

[0018] 2. By setting up an internal expansion repair component consisting of honeycomb repair columns, a moisture equalization plate, and a permeable core column, the water source is evenly dispersed by the moisture equalization plate and then slowly permeates and dissolves in the porous channels of the honeycomb repair columns to form a continuous and stable repair solution. At the same time, the bottom support component locks the position of the honeycomb repair columns, and the dilution filter adjusts the concentration of the repair solution, solving the problems of uneven release of repair agent, positional deviation, and excessive concentration, and providing a stable source of repair solution for directional leakage.

The inclined outlet on the bottom slope slowly guides the fluid to prevent loss, while the straight outlet on the top slope discharges the fluid horizontally to extend the residence time. In conjunction with the filling permeable plate to release auxiliary media, the problem of one-way loss of repair fluid and uneven repair on the top and bottom slopes is solved, achieving balanced coverage and coordinated repair.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] This application provides a mine soil ecological restoration device that solves the problems of traditional restoration methods, such as the reliance on natural infiltration of restoration agents leading to easy loss and unstable restoration effects, as well as the unidirectional loss of restoration fluid downhill due to gravity and uneven restoration on slopes. When in use, this invention integrates the surface restoration layer and the internal expansion restoration components through the grid-like layout of reinforced hard netting and anchoring cylinders, forming a three-dimensional restoration network that extends from points to surfaces and links the inside and outside.

[0036] The technical solutions in this application are intended to solve the above-mentioned technical problems, and the overall approach is as follows.

[0037] Example 1, please refer to Figures 1-12 This application provides a mine soil ecological restoration device, including a slope 1, a reinforcing hard net 2 installed on the slope 1, and a plurality of planting grids 3 arrayed on the reinforcing hard net 2. Positioning ladder holes 4 are provided at the intersections of the planting grids 3, and anchoring cylinders 5 are installed inside the positioning ladder holes 4. A surface restoration layer 6 is provided on the planting grids 3. An internal expansion restoration component 7 is provided inside the anchoring cylinder 5, and a guiding leakage component 8 is provided at the bottom of the anchoring cylinder 5. The internal expansion restoration component 7 includes: a honeycomb restoration column 71 placed inside the anchoring cylinder 5 and a moisture equalization plate 72 located at the top of the honeycomb restoration column 71 and fixed to the upper side of the inside of the anchoring cylinder 5. A permeable core column 73 is installed at the top of the moisture equalization plate 72. External water enters the moisture equalization plate 72 through the permeable core column 73 and permeates to the top surface of the honeycomb restoration column 71, then permeates downwards through the honeycomb restoration column 71 to form a restoration liquid. The restoration liquid diffuses to the inner soil layer through the guiding leakage component 8 and simultaneously restores the surface and inner soil layers with the surface restoration layer 6.

[0038] Furthermore, the moisture equalization disc 72 is a flat disc body, and the interior of the moisture equalization disc 72 is filled with guide fibers; the guide fibers are hydrophilic fiber bundles, which evenly distribute the water flow entering from the permeable core column 73 to the entire bottom surface of the moisture equalization disc 72.

[0039] In the preferred embodiment of this solution, this application integrates the surface repair layer 6 and the inner expansion repair component 7 through the grid-like layout of the reinforced hard mesh 2 and the anchoring cylinder 5, forming a three-dimensional repair network that extends from point to surface and links the inside and outside. This solves the problems of easy loss of repair agent and disconnection between surface and inner repair in the existing slope 1 repair technology, and achieves efficient and balanced repair of the soil of the mine slope 1.

[0040] Specifically, the restoration process of the soil ecological restoration equipment in this mine is as follows: First, the surface of the mine slope 1 is cleaned and loosened. The reinforcing mesh 2 is laid on the surface of the slope 1. Then, the anchoring cylinder 5 is vertically inserted into the positioning ladder hole 4. The bottom end of the bottom sleeve 81 of the anchoring cylinder 5 is provided with a bottom cone 811 and a fixed inclined block 812, which can improve the stability of the anchoring cylinder 5 in the soil of the slope 1 and prevent loosening or displacement. Second, when external rainwater or artificial irrigation water falls on the surface of the reinforced hard net 2, it is collected and guided by the concave arc groove 21 on the vertical strip of the reinforced hard net 2. The arc of the concave arc groove 21 matches the permeable core column 73 at the top of the anchoring cylinder 5, so that the water source flows into the top opening of the permeable core column 73 along the concave arc groove 21 and enters the interior of the anchoring cylinder 5. Third, after the water source enters the permeable core column 73, it flows downward to the moisture equalization plate 72. The hydrophilic guiding fiber filled inside the moisture equalization plate 72 uses capillary action to evenly disperse the water source to the entire bottom surface of the moisture equalization plate 72 and penetrate to the top surface of the honeycomb repair column 71. The water source flows from top to bottom through the porous channels of the inner honeycomb core 712 of the honeycomb repair column 71. During the slow penetration process, it dissolves the repair agent to form a repair liquid. The repair liquid flows vertically downward from the bottom of the inner honeycomb core 712. Meanwhile, the bottom end of the honeycomb repair column 71 is supported and positioned by the bottom support assembly 9, the hollow twisting disc 91 is threadedly installed at the bottom of the anchoring cylinder 5, and the top of the cross support 92 abuts against the bottom end of the honeycomb repair column 71 to ensure the stability of the position of the honeycomb repair column 71. The repair liquid flowing out of the honeycomb repair column 71 achieves a concentration gradient decrease through the dilution filter 93, and then enters the bottom of the anchoring cylinder 5. Fourth, the repair fluid enters the guide leakage component 8 at the bottom of the anchoring cylinder 5. After dripping onto the top of the conical platform 83, the repair fluid slides evenly down the conical surface to the surrounding area. A partition plate 84 is provided in the middle of the top of the conical platform 83, which divides the internal cavity 82 into a slope-down chamber and a slope-up chamber. The repair fluid sliding down the conical surface enters the corresponding chambers respectively: the outer wall of the slope-down chamber is provided with a slope-down slow-discharge ring 85 facing the downhill direction of the slope 1, and the outer wall of the slope-up chamber is provided with a slope-up even-discharge ring 86 facing the uphill direction of the slope 1. Several inclined discharge ports 851 are opened at equal intervals on the slope-down slow-discharge ring 85. The repair fluid is discharged from the inclined downward discharge ports and enters the soil in the downhill direction under the action of gravity. Several straight discharge ports 861 are opened at equal intervals on the slope-up even-discharge ring 86. The repair fluid is discharged from the horizontal discharge ports and directly enters the soil in the uphill direction, prolonging the residence time to facilitate capillary diffusion. At the same time, the inclined discharge ports 851 and the straight discharge ports 861 are filled with slow-release filler to regulate the release rate of the repair fluid. It should be noted that the guiding function of this leakage guiding component 8 is only to accurately guide the repair fluid from inside the anchoring cylinder 5 to the corresponding areas on the uphill and downhill slopes of the slope 1. The final diffusion of the repair fluid in the soil still depends on the soil's own infiltration. Unlike natural infiltration, with the reasonable layout of the anchoring cylinder 5, the infiltration of the repair fluid can gradually diffuse from a single anchoring point to the entire slope 1 area, achieving point-to-surface repair coverage, rather than forcibly changing the soil's permeability characteristics through the component itself. Secondly, both sides of the partition plate 84 are provided with sliding grooves 841, and a filling permeable plate 842 is slidably installed in the sliding grooves 841. The filling permeable plate 842 is filled with auxiliary repair medium. When the repair liquid first falls and flows through the filling permeable plate 842, it will dissolve the auxiliary repair medium and carry it out together, so as to achieve the synergistic repair effect of multiple repair media. Fifth, simultaneously, from bottom to top, functional layers are laid in the planting grid 3: a base nutrient layer 61, a herb seed layer 62, a water-retaining covering layer 63, and a lower liquid treatment layer 64. The base nutrient layer 61, herb seed layer 62, and water-retaining covering layer 63 work together to provide good conditions for herb seed germination. The liquid treatment layer 64, with its bottom water-guiding wire 641, can guide some water and remediation solution to the soil surface, repairing the surface soil. As the herb plants gradually grow, their roots will slowly penetrate into the inner soil of the slope 1, fully contacting the remediation solution discharged by the guide seepage component 8, thus forming a root and remediation solution composite remediation zone, further enhancing the soil remediation effect. Sixth, each time there is rainfall or artificial irrigation, the water source enters the anchoring cylinder 5 again through the concave arc groove 21, repeating the above repair process. The inner honeycomb core 712 of the honeycomb repair column 71 continuously releases the repair agent until it is completely consumed. After the inner honeycomb core 712 is exhausted, the hollow twisting plate 91 at the bottom of the anchoring cylinder 5 can be unscrewed to replace the honeycomb repair column 71, so that the equipment can be reused for a long time.

[0041] In this embodiment, please refer to Figure 7 The honeycomb repair column 71 includes an outer conformal shell 711 and an inner honeycomb core 712. The outer conformal shell 711 is a rigid shell, and the inner honeycomb core 712 is filled inside the outer conformal shell 711. The inner honeycomb core 712 has a porous structure. When water flows from top to bottom through the inner honeycomb core 712, it slowly dissolves to form a repair liquid, which flows out from the bottom of the inner honeycomb core 712.

[0042] In a preferred embodiment of this solution, by setting a double-layer composite structure of an outer conformal shell 711 and an inner honeycomb core 712, when water flows from top to bottom through the porous channels of the inner honeycomb core 712, it comes into full contact with the repair medium therein and slowly dissolves, forming a repair liquid that flows out from its bottom end. Secondly, the outer conformal shell 711 is a rigid structure that can stably maintain the overall shape of the honeycomb repair column 71, while also providing support and protection for the internal honeycomb core. The porous structure of the inner honeycomb core 712 can slow down the water infiltration rate and ensure uniform concentration of the repair solution. This combination of outer conformal protection and inner liquid release ensures a continuous and stable outflow of the repair solution, providing a stable source for subsequent gradient dilution, directional leakage, and synergistic repair of the repair solution, thereby improving the repair efficiency and quality of the mine slope 1 soil.

[0043] In this embodiment, please refer to Figure 6 The anchoring cylinder 5 is provided with a bottom support assembly 9 at the lower part to lock the position of the honeycomb repair column 71. The bottom support assembly 9 includes a hollow torsion plate 91 and a cross support frame 92. The hollow torsion plate 91 is threadedly installed at the lower part of the anchoring cylinder 5, and the cross support frame 92 is installed on the upper part of the inner ring wall of the hollow torsion plate 91. The top of the cross support frame 92 abuts against the bottom end of the honeycomb repair column 71. A dilution filter screen 93 is installed on the lower part of the inner ring wall of the hollow torsion plate 91.

[0044] In the preferred embodiment of this solution, by setting up a hollow torsion plate 91, a cross support 92, and a dilution filter 93, the height of the cross support 92 can be adjusted by rotating the hollow torsion plate 91 during operation, locking the position of the honeycomb repair column 71. After the repair fluid flows out from the bottom of the honeycomb repair column 71, it is adjusted in concentration by the dilution filter 93 before flowing into the bottom of the anchoring tube 5. This avoids displacement and shaking of the honeycomb repair column 71 in the anchoring tube 5, which would cause unstable flow of the repair fluid. It also avoids the problem of media waste, excessive local repair, and inability to adapt to subsequent directional leakage caused by the direct flow of repair fluid with excessively high concentration.

[0045] In this embodiment, please refer to Figure 3 The vertical strips of the reinforced hard mesh 2 are provided with concave arc grooves 21; the tops of the anchoring cylinder 5 and the permeable core column 73 are matched with the arc of the concave arc groove 21, which is used to guide rainwater or external water sources into the anchoring cylinder 5.

[0046] In the preferred embodiment of this solution, by setting an inner concave arc groove 21, rainwater or external water sources fall on the surface of the reinforced hard mesh 2 and quickly converge through the inner concave arc groove 21. With the help of the curvature adaptability, the water flows directionally into the anchoring cylinder 5, providing a stable water source for the subsequent formation of the repair fluid. This solves the problems of water source being easily lost on the surface of the slope 1, unable to be collected and utilized efficiently, and chaotic flow direction, making it difficult to accurately introduce the water into the anchoring cylinder 5, resulting in unstable formation of the repair fluid and waste of water resources.

[0047] In this embodiment, please refer to Figure 9 and Figure 10 The guide leakage component 8 includes: a bottom sleeve 81, threadedly installed at the bottom of the anchoring sleeve 5; an internal cavity 82, opened in the middle of the bottom sleeve 81; a conical platform 83 installed at the bottom of the internal cavity 82, and a partition plate 84 installed at the middle of the top of the conical platform 83, which divides the internal cavity 82 into a downhill chamber and an uphill chamber; a downhill drainage ring 85, disposed on the outer wall of the downhill chamber and facing the downhill direction of the slope 1; and an uphill drainage ring 86, disposed on the outer wall of the uphill chamber and facing the uphill direction of the slope 1.

[0048] Further, please refer to Figure 9 and Figure 10 The slope-downward-sloping drainage ring 85 has several inclined drainage outlets 851 at equal intervals; the slope-upward-sloping drainage ring 86 has several straight drainage outlets 861 at equal intervals; both the inclined drainage outlets 851 and the straight drainage outlets 861 are filled with slow-release filler.

[0049] In the preferred embodiment of this solution, a guiding leakage component 8 is provided, consisting of a bottom sleeve 81, an internal cavity 82, a conical platform 83, a partition plate 84, a slope-downward slow-drainage ring 85, and an up-slope uniform-drainage ring 86. During operation, the repair fluid is evenly distributed to the two chambers through the conical platform 83, and then through outlets in different directions combined with slow-release filler, achieving differentiated leakage with slow-speed guidance in the downhill direction and uniform retention in the uphill direction. This solves the problem that the repair fluid is easily lost unidirectionally in the soil of slope 1 due to gravity, resulting in over-repair on the downhill side and insufficient repair on the uphill side, thus making the overall repair range balanced. Meanwhile, the threaded bottom sleeve 81 facilitates component disassembly and maintenance, and the conical platform 83 and the partition plate 84 work together to achieve precise bidirectional diversion of the repair fluid, adapting to the terrain characteristics of slope 1. In addition, the differentiated settings of the inclined outlet 851 and the straight outlet 861, combined with the slow-release filler, can adjust the leakage rate and residence time according to the stress characteristics of the upslope 1, preventing the rapid loss of repair fluid on the downslope side and ensuring sufficient penetration of repair fluid on the upslope side.

[0050] In this embodiment, please refer to Figure 9 and Figure 10Both sides of the partition plate 84 are provided with sliding grooves 841, and a filling liquid permeable plate 842 is slidably installed in the sliding grooves 841. The filling liquid permeable plate 842 is filled with auxiliary repair medium.

[0051] In the preferred embodiment of this solution, by setting up a chute 841 and a filling permeable plate 842, when the repair fluid flows through the filling permeable plate 842 during operation, the auxiliary repair medium therein can be dissolved and discharged together, realizing the synergistic repair of multiple repair media. This solves the problems of inconvenient addition of auxiliary repair media, difficulty in fully mixing with the repair fluid, inflexible replacement of auxiliary media, and attenuation of effect after long-term use. The auxiliary repair medium filled in the liquid-permeable plate 842 can be selected from one or more of biochar, humic acid, microbial agents or nutrients, and is used to work synergistically with the main repair agent to improve the repair effect and promote vegetation growth.

[0052] In this embodiment, please refer to Figure 9 and Figure 10 The bottom end of the bottom sleeve 81 is equipped with a bottom cone 811, and several fixed inclined blocks 812 are installed in a ring at equal intervals around the bottom cone 811.

[0053] In the preferred embodiment of this solution, by setting a bottom cone 811 and a fixed inclined block 812, during operation, the bottom cone 811 can guide the bottom sleeve 81 to be quickly and smoothly inserted into the soil of the slope 1. After the fixed inclined block 812 is embedded in the soil, it forms multi-point support, which enhances the overall anchoring stability. This solves the problems of high resistance and difficulty in positioning when the bottom sleeve 81 is inserted into the soil, as well as the easy displacement and tilting after insertion due to the slope of the slope 1 and the loosening of the soil, which leads to insufficient overall stability of the anchoring cylinder 5, affecting the directional leakage of the repair fluid and the long-term operation of the equipment.

[0054] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 12 The surface repair layer 6 includes a base nutrient layer 61, a herb seed layer 62, and a water-retaining covering layer 63. The base nutrient layer 61 is laid at the bottom of the planting grid 3, the herb seed layer 62 is laid on top of the base nutrient layer 61, and the water-retaining covering layer 63 is laid on top of the herb seed layer 62. A medicinal liquid layer 64 is provided at the bottom of the base nutrient layer 61, and a water-guiding wire 641 is provided at the bottom of the medicinal liquid layer 64.

[0055] In the preferred embodiment of this scheme, a surface repair layer 6 is set up, consisting of a base nutrient layer 61, a herb seed layer 62, and a water-retaining covering layer 63. The water-retaining covering layer 63 locks in water, the base nutrient layer 61 provides fertilizer, and the herb seed layer 62 provides the foundation for vegetation, which synergistically improves the seed germination rate and vegetation survival rate, and achieves surface vegetation coverage of slope 1. The liquid treatment layer 64, together with the water-conducting wire 641, can accurately guide water and repair solution to the soil surface, realize the linkage between deep repair and surface repair, improve the overall repair effect, and after the subsequent vegetation grows, the root system can further stabilize the soil and prevent erosion, consolidate the repair results, and improve the long-term effectiveness and stability of the soil repair of the mine slope 1.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
