A slope ecological restoration system and operation method based on vegetation hole environmental protection sleeve

Abstract

This invention discloses a slope ecological restoration system and operation method based on an environmentally friendly sleeve with vegetation holes, aiming to improve the water and fertilizer infertility conditions of hard slopes through the design of the vegetation hole structure. The device includes two components: a biodegradable sleeve and a vegetation bag. The biodegradable sleeve consists of an outer cylinder A, a middle cylinder B, and an inner cylinder C nested together. The vegetation bag device has an inner and outer cylinder, with both the inner and outer surfaces of the inner cylinder having a frosted finish. An internal telescopic device compresses the material during the grinding process, improving the grinding effect and preventing the hardening and consolidation of fertilizer after repeated dissolution by water flow. The environmentally friendly sleeve structure of this invention is simple to manufacture and easy to implement. When applied to slopes, it prevents the spraying substrate from clogging the vegetation holes during hydroseeding. The vegetation bag absorbs excess water from the vegetation holes and replenishes them with new nutrients. Maintaining a high level of nutrients within the vegetation holes significantly improves plant survival rates.

Description

Technical Field

[0001] This invention relates to the field of slope engineering protection and ecological restoration, and in particular to a slope ecological restoration system and operation method based on a vegetation hole environmentally friendly sleeve. Background Technology

[0002] During the rapid socio-economic development, numerous engineering projects have damaged the original structure of mountain slopes, reducing slope stability and causing vegetation destruction and soil erosion. Existing slope protection and ecological restoration technologies have, to some extent, solved the safety, stability, and vegetation restoration problems of conventional slopes (such as soil slopes, soil-rock mixed slopes, and fractured soft rock slopes). However, for hard slopes with challenging habitat conditions, especially intact hard rock slopes and existing artificially hardened slopes (such as concrete slopes and masonry slopes), there are still shortcomings in achieving the storage and connectivity of slope water and nutrients to create sustainable habitats. This leads to low plant survival rates, slow growth, and unsustainable vegetation restoration.

[0003] For example, patent announcement number CN222263746U discloses a greening device for mine remediation, which uses planting boxes to fix vegetation and plant soil, solving the problem of nutrient supply for early plant growth, but lacks consideration for the continuous supply of nutrients and water in the later stages. Patent announcement number CN118895774B discloses a slope greening device that creates habitats through ecological bags and anchoring devices, but does not solve the problem of nutrient and water connectivity between the planting bags. Patent announcement number CN219491025U sets planting holes on the surface of high and steep intact rock slopes, but the planting holes are not connected and there is no external source of water and nutrients. The storage and utilization of nutrients and water are limited to a single planting hole, making it difficult to achieve sustainability.

[0004] While the aforementioned technical solutions address the issues of stabilization on steep slopes and hard rock slopes, and nutrient supply during the early stages of plant growth, they fail to consider the connectivity of nutrients and water, and the sustainable supply of nutrients and water in the later stages of ecological restoration. This leads to low plant survival rates, slow growth rates, and unsustainable ecological restoration. Therefore, it is necessary to design a slope ecological restoration system and operation method based on environmentally friendly sleeves with vegetation holes to solve these problems. Summary of the Invention

[0005] The technical problem this invention aims to solve is to provide a slope ecological restoration system and operation method based on an environmentally friendly sleeve with planting holes. This solution aims to address the problems of poor water and nutrient connectivity, unsustainable supply, low plant survival rate, and slow growth rate in existing technologies. The system is compact, easy to use, and the materials used are biodegradable, environmentally friendly, and provide nutrients for plant growth. The device connects the planting holes to the planting bags, which in turn connect to an external water tank. This ensures automatic storage and continuous supply of water and nutrients to the slope, while also enabling the connectivity, exchange, and regulation of water, nutrients, air, and other substances and energy, thereby improving plant survival rate, promoting plant growth, and ultimately achieving sustainable slope ecological restoration.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A slope ecological restoration system based on environmentally friendly sleeves for planting holes includes a biodegradable sleeve assembly, which consists of an outer sleeve A, a middle sleeve B, and an inner sleeve C, which are nested together in sequence. A planting bag assembly is connected to the biodegradable sleeve assembly and is used to transport nutrients and water into the planting holes. The bottom of the outer sleeve A is a conical water collection hopper, which is filled with coconut coir, hydrophobic material, and water-absorbing material. A circular hollow first PVC pipe is located in the center, and the outer wall of the pipe has eight holes, divided into two groups of four, for connection with the middle sleeve B and for air circulation in the planting holes.

[0008] The middle cylinder B has a bottomless structure with a second PVC pipe in the center. Inside the middle cylinder B, there is a telescopic control structure consisting of a PVC spring, support rod, and buckle. The telescopic control structure is connected to the second PVC pipe and is used to control telescopic movement and fixation. The outer cylinder A is connected to the middle cylinder B by a crossbar made of sawdust material to fix the first and second PVC pipes located at the center of cylinders A and B. A track structure is set on the outside of the first PVC pipe. The telescopic control structure slides up and down along the track. The telescopic control structure is made of wood chips. The outer protrusion can extend outward to fix itself when it encounters a hole on the first PVC pipe. The support rod structure has a groove to allow the outer protrusion to retract inward and slide along the track. During the sliding process, the spring is compressed. When the outer protrusion slides to the next hole, the spring is released to unfold the outer protrusion.

[0009] The inner cylinder C has a bottom-open structure and the inner layer is made of loofah sponge. There are gaps at the top and bottom around the inner cylinder C to accommodate the crossbars of the outer cylinder A and the middle cylinder B, which serve as a limit. A square hollow tube is set in the center of the inner cylinder C, which can be connected to the first PVC pipe and the second PVC pipe of the outer cylinder A and the middle cylinder B to form an air-conducting tube for the plant.

[0010] Furthermore, when laying the base layer, the outer cylinder A can serve as the elevation. When the base layer is laid to the top of the outer cylinder A, the process stops. At this point, press the spring clip structure inside the middle cylinder B. The spring is made of PVC material, which can raise the middle cylinder B and the inner cylinder C together to a certain height until the spring clip structure is locked again. At this point, the middle cylinder B can provide the elevation. When the surface layer is laid to the top of the middle cylinder B, the process stops.

[0011] Furthermore, when the surface layer construction reaches the height of the middle cylinder B, the surface layer spraying is stopped. The inner cylinder C can be lifted upwards and filled with soil and plants. At this time, the upper bottom becomes the lower bottom, and the inwardly curved loofah sponge layer is fully unfolded and inserted into the planting hole. The sawdust material on the lower side of the middle cylinder B is relatively fragile. When the inner cylinder C is filled with soil and placed inside the middle cylinder B, the protruding structure below the middle cylinder B can be destroyed to ensure that the planting hole is filled with soil.

[0012] Preferably, the bottom of the outer cylinder 3 extends inward by 1-2 cm, which matches the lower outer cylinder of the middle cylinder B which contracts inward by 1-2 cm. The two cylinders are nested together to form a space for storing nutrients. When the base layer is sprayed and the middle cylinder B is lifted upward, this space is released, and the nutrients fall to the bottom to provide nutrients for the early growth of the plants.

[0013] Preferably, the outer cylinder A has an outwardly extending square structure on its outer side, which can be connected to the wooden panel of the planting bag to achieve the connection of nutrients and water. The square structure is fixed to the wooden panel of the planting bag by buckles or rivets.

[0014] Preferably, the second PVC pipe at the center of the middle cylinder B is circular at the bottom and square at the top, respectively cooperating with the first PVC pipe of the outer cylinder A and the square hollow pipe of the inner cylinder C to form an integral air-guiding pipe structure. The air-guiding pipe has holes evenly arranged in the pipe body to increase the oxygen content of the soil in the planting holes.

[0015] Preferably, the inner cylinder C has a round hole at its top and bottom to facilitate upward lifting by workers during construction. The upper and lower parts of the inner cylinder C are made of sawdust material, and the middle part is a compressible area combining non-woven fabric and loofah sponge. When filling with soil, this area is stretched, so that the inner cylinder C, which is originally smaller than the overall planting hole, becomes longer after filling with soil, allowing the planting hole to be filled with soil. The material used in the compressible area can effectively absorb water, maximize the absorption of nutrients from the planting bag, and keep the nutrients in this area to supply plant growth.

[0016] Furthermore, the compression structure is made of water-absorbing material, which can effectively catch the nutrient-rich water from the planting bag and retain the nutrients in the area for easy absorption by the plant growth.

[0017] Preferably, the planting bag assembly includes a second inner cylinder and an outer cylinder. The inner and outer surfaces of the second inner cylinder are both frosted. Two small cylindrical protrusions are evenly arranged on the outer side of the second inner cylinder and are tightly connected to the second inner cylinder, allowing them to rotate in unison. An internal telescopic device is provided to improve the nutrient dissolution rate by squeezing the material against the frosted surface. A through-hole rod penetrating the planting bag is provided at the center of the second inner and outer cylinders. Holes are evenly arranged on the surface of the through-hole rod to allow water to flow out after water is injected. An auger and a stirring rod are also provided. The through-hole rod can drive the auger and stirring rod to rotate. The stirring rod is arranged below the feed inlet to initially crush the material, and then the material is transferred to the telescopic devices on both sides for fine grinding by the auger.

[0018] The top of the vegetation bag assembly is equipped with a cover plate, which can be lifted upwards to add materials. The cover plate has a snap-fit ​​structure inside, which can limit the opening range of the cover plate and provide a foothold for workers to work on the slope. When the cover plate is closed, it is flush with the surface layer, providing workers with working space on the slope. Hooks are arranged around the bottom of the wooden panel of the vegetation bag assembly at the vegetation bag inlet, which can be combined with galvanized mesh to fix the vegetation bag to the hard slope. The hooks and galvanized mesh are connected by snaps or rivets to ensure the stability of the vegetation bag on the hard slope.

[0019] Furthermore, hooks are arranged around the bottom of the feed inlet panel of the planting bag to fix the size of the cover plate, making it convenient for workers to step on it to work. The cover plate is flush with the surface layer, which can provide workers with working space on the slope.

[0020] Preferably, both ends of the planting bag are equipped with gears, including an external gear, an inner cylinder half-wheel, and a telescopic device gear. The entire planting bag is driven by the inner cylinder half-wheel to rotate the other gears. The external gear and the inner cylinder half-wheel cooperate to make the telescopic device gear rotate alternately counterclockwise and clockwise. Under the alternating rotation of the telescopic device gear, the upper baffle is driven to rotate alternately. The upper baffle has an arc-shaped strip structure. Under the alternating rotation of the upper baffle, the telescopic rod can extend and retract along the slide groove. The extension and retraction of the telescopic rod can squeeze the material against the inner wall and improve the grinding efficiency.

[0021] Preferably, a soft water pipe is installed above the planting bag structure to serve as a water storage unit. When the water storage unit on the upper side of the planting bag stores enough water, the water is drained through the water pipe to make the turbine fan inside the cylinder rotate. There are two cylindrical protrusions on the back of the planting bag. Inside the cylinder, there is a turbine structure with a diameter slightly smaller than the cylinder diameter, which contains a rotating wheel. When the water flow from the upper part impacts, it can drive the lower turbine to rotate. The lower turbine fan can engage with the small cylindrical protrusions on the inner cylinder to make the second inner cylinder rotate and grind. Finally, the nutrient-rich water flows back into the planting bag.

[0022] Preferably, the planting bag assembly can be connected in series, with each planting bag connected by rods and interlocking plates. The rods are equipped with water outlets to allow water flow. The rods and interlocking plates are connected by snap-fit ​​connections to ensure a secure connection between the planting bags and smooth water flow. The first section of the planting bag assembly is equipped with a motor output inlet, which controls the turbine and the circular tube penetrating the planting bag. A micro motor is placed inside to provide power, driving the water flow and grinding device. The turbine and the circular tube are driven by gears to ensure the efficient operation of the water flow and grinding device.

[0023] Furthermore, the planting bag structures are connected in series. Each planting bag structure consists of three rotating rods to prevent transmission problems caused by inconsistent heights of the planting bags during actual construction. A motor output inlet is provided at the end of each row of planting bags. Through the inlet, the turbine and the through-tube passing through the planting bag are controlled respectively. The worker can start the micro motor to make the turbine fan and the lateral gear rotate. The rotation of the turbine fan can increase the flow rate of water in the water pipe. The lateral gear can drive the through-tube passing through the planting bag, thereby providing power for the grinding device of the planting bag. The worker can put the electric screwdriver motor into it to provide power. The turbine fan can increase the flow rate of water inward and control the rotation of the tube.

[0024] Furthermore, the outer shell of the planting bag has an outer panel that can be connected to the planting hole, and both ends of the outer shell have gears and three fixed gears to ensure the safe rotation of the second inner cylinder.

[0025] Furthermore, there are multiple sets of telescopic devices inside the plant bag structure, which are controlled by a circular tube that runs through the whole structure. While the second inner cylinder of the structure rotates, the telescopic structure below unfolds alternately to squeeze the material and the inner wall abrasive structure to increase the grinding efficiency. A stirring rod is arranged in the middle for initial crushing, and then the auger devices on both sides transport the material to the telescopic structures on both sides for fine grinding.

[0026] Furthermore, the top of the planting bag structure can be lifted upwards to add materials for long-term use. When not in use, the cover is flush with the surface layer. The cover can be lifted upwards, and the internal snap-fit ​​structure of the cover limits the opening range, providing a foothold for workers on the slope and facilitating construction. When closed, the cover is flush with the surface layer. Hooks are arranged around the bottom of the planting bag inlet panel, and the internal snap-fit ​​structure of the cover can fix the size of the cover's movement to provide workers with working space. Hooks are also arranged around the square bottom of the planting tube to be fixed in conjunction with galvanized mesh.

[0027] Furthermore, the planting bags are connected in series, with rods and interlocking plates between each pair of planting bags. Water outlets are arranged on the rods to allow water to flow through. The bags are then fixed to both sides by circular plates, so that the rotation of one end drives the rotation of the next. Soft thin tubes protect the connection points to prevent soil from entering and affecting the transmission efficiency.

[0028] Furthermore, after the planting bags are connected in series, they are connected to a water pipe at the end, where a micro motor inlet, a turbine fan, and a lateral gear are arranged. When the valve is opened, water flows from the water pipe to the planting bag. The output port of the micro motor is placed into the end inlet to start the micro motor electric screwdriver, which is inserted into the screwdriver inlet to rotate. One side drives the turbine fan to increase the water flow rate, and the other side drives the lateral gear to rotate, thereby driving the grinding of the through hole and the subsequent planting bag.

[0029] Preferably, the operation method of the slope ecological restoration system based on the vegetation hole environmental protection sleeve includes the following steps:

[0030] S1, Set the planting holes on the hard slope and fill the planting holes with biodegradable sleeve components; Connect the planting bags to the biodegradable sleeve components through wooden panels, and fix them to the hard slope with rivets on the other side; Connect the planting bags in series and protect the connection with hoses, and carry out base spraying work on the hard slope, controlling the height of base spraying to the top of the outer cylinder A.

[0031] S2, fix the galvanized mesh to the hook at the top of the planting bag, then lift the middle cylinder B and carry out the surface spraying operation until the height reaches the top of the middle cylinder B;

[0032] S3, take out the inner cylinder C, turn it over, fill the inner cylinder C with soil and plants, and then place the inner cylinder C into the planting hole;

[0033] S4. After fixing the planting bags and biodegradable sleeve components on the slope, start the water pump to let the water flow into the planting bags through the pipe. Open the valves at the ports of each row of planting bags in sequence, put the output port of the micro motor into the end inlet, start the micro motor, and use the power of the micro motor to drive the water flow into the planting bags and start the grinding device inside the planting bags to work.

[0034] Furthermore, after fixing the planting bags and biodegradable sleeve components to the slope, the water pump below the slope is started to transport water upwards. Then, an electric screwdriver is used to insert the water into the starting point of each planting bag, and the electric screwdriver drives the water flow into the planting bag and starts the grinding device inside the planting bag.

[0035] The beneficial effects of this invention are as follows:

[0036] 1. By bonding the plant fibers of the loofah sponge layer and the sawdust layer, a cup-shaped (cylindrical) sleeve structure is formed and fits into the planting hole. This method is convenient to construct, and the pressure generated by the filling material inside the sleeve, as well as the expansion force generated by the expansion of the loofah sponge layer upon contact with water, continuously compresses the hole wall. This not only secures the sleeve but also improves the overall stability of the slope. Simultaneously, the degradation and utilization of the sawdust layer provides a source of nutrients for the plants later on. This invention facilitates the outward seepage of excess water from the planting hole, reducing the risk of root rot caused by excessive moisture. Furthermore, when the substrate is dry, the water-absorbing material and the sleeve can absorb and store some water, alleviating water shortage in the plants.

[0037] 2. The planting hole sleeve structure of the present invention can provide workers with elevation indicators during hydroseeding. The base layer and surface layer are laid to a certain height and then stopped. During the spraying of the base layer and surface layer, the planting hole opening is in a closed state. After the surface layer construction is completed, the soil filling in the cylinder is turned over to prevent the sprayed material from entering the planting hole during the hydroseeding operation. The machine and labor costs are reduced when the inner cylinder C is filled and turned over to be placed into the planting hole.

[0038] 3. This invention provides nutrients in the planting hole at the early stage of plant growth. There is a round tube in the plant root system that can exchange oxygen with the outside. Water with nutrients flows into the planting hole from the outside. The non-woven fabric and loofah in the inner cylinder C closest to the plant can receive most of the nutrients to supply the plant, thereby improving the survival rate of the plant at all stages.

[0039] 4. The vegetation bag structure of the present invention has an opening on the surface layer, which can be added and replenished according to the material usage, so as to achieve long-term maintenance of ecological restoration. In addition, the opening plate can limit the opening range, provide a standing point for workers to work on the slope, ensure worker safety and improve work efficiency.

[0040] 5. The planting bag structure of the present invention can perform autonomous grinding by water flow in an unmanned state, and guide the nutrient-containing water flow to the planting hole. In addition, workers can use a hand-held screwdriver to provide power to introduce external water sources for irrigation, reducing labor costs. Furthermore, the water flow inside the pipe is sent into the planting hole through the pump body, reducing water evaporation and improving water utilization.

[0041] 6. This invention can autonomously use the accumulated water to impact the turbine located on the back of the planting bag. The kinetic energy of the downward flow of water causes the turbine and turbine fan to rotate, thereby driving the rotation of the inner cylinder of the planting bag and activating the grinding device inside the planting bag. It also guides the nutrient-containing water to the planting holes. The number of times the grinding and irrigation of the plants in the planting holes can be increased manually. Workers start the water pump and the micro motor at the end of the planting bag to drive the water flow in and start the grinding device. This reduces the input of labor costs and sends the water from inside the pipe into the planting holes through the pump body, reducing water evaporation and improving water utilization.

[0061] Example 1:

[0062] like Figures 1-3 As shown, a slope ecological restoration system based on an environmentally friendly sleeve with a planting hole 41 includes a biodegradable sleeve assembly, which consists of an outer sleeve A3, a middle sleeve B6, and an inner sleeve C9, which are nested together in sequence; a planting bag 54 assembly is connected to the biodegradable sleeve assembly and is used to transport nutrients and water into the planting hole 41.

[0063] like Figure 4 As shown, the bottom of the outer cylinder A3 is a conical water collection hopper 4, which is filled with coconut coir, hydrophobic material and water-absorbing material. The center is provided with a circular hollow first PVC pipe 2. The outer wall of the pipe has eight holes, divided into two groups of four, which are used for connection with the middle cylinder B6 and for air circulation in the planting hole 41.

[0064] like Figure 5As shown, the middle cylinder B6 has a bottomless structure with a second PVC pipe 5 at its center. Inside the middle cylinder B6, there is a telescopic control structure consisting of a PVC spring 16, a support rod 15, and a buckle. The telescopic control structure is connected to the second PVC pipe 5 and is used to control telescopic movement and fixation. The outer cylinder A3 is connected to the middle cylinder B6 by a crossbar 1 made of sawdust material, which is used to fix the first PVC pipe 2 and the second PVC pipe 5 located at the center of cylinders A and B. A track 13 structure is set outside the first PVC pipe 2. The telescopic control structure slides up and down along the track 13. The telescopic control structure is made of wood chips. The outer protrusion 14 can extend outward to fix itself when it encounters a hole on the first PVC pipe 2. The support rod 15 has a groove in its structure, which allows the outer protrusion 14 to retract inward and slide on the track 13. During the sliding process on the track 13, the spring 16 is compressed. When the outer protrusion 14 slides to the next hole, the spring 16 is released, causing the outer protrusion 14 to unfold.

[0065] like Figures 6-8 As shown, the inner cylinder C9 has a bottom-opening structure and the inner layer is made of loofah sponge material. The upper and lower parts of the inner cylinder C9 have gaps around the cylinder body to accommodate the crossbars 1 of the outer cylinder A3 and the middle cylinder B6, which serve as a limiting function. A square hollow tube 10 is set in the center of the inner cylinder C9, which can be connected to the first PVC pipe 2 and the second PVC pipe 5 of the outer cylinder A3 and the middle cylinder B6 to form a gas-conducting tube for the plant.

[0066] Furthermore, when laying the base layer 38, the outer cylinder A3 can serve as the elevation. When the base layer 38 is laid to the top of the outer cylinder A3, the process stops. At this time, the spring 16 buckle structure inside the middle cylinder B6 is pressed. The spring 16 is made of PVC material and can lift the middle cylinder B6 and the inner cylinder C9 together to a certain height until the spring 16 buckle structure is locked again. At this time, the middle cylinder B6 can provide the elevation. The process stops when the surface layer 39 is laid to the top of the middle cylinder B6.

[0067] Furthermore, when the surface layer 39 reaches the height of the middle cylinder B6, the surface layer 39 stops spraying. The inner cylinder C9 can be lifted upwards and filled with soil and plants. At this time, the upper bottom becomes the lower bottom, and the inwardly curved loofah sponge layer is fully unfolded and inserted into the planting hole 41. The sawdust material on the lower side of the middle cylinder B6 is relatively fragile. When the inner cylinder C9 is filled with soil and placed inside the middle cylinder B6, the protruding structure below the middle cylinder B6 can be destroyed to ensure that the planting hole 41 is filled with soil.

[0068] Preferably, the bottom of the outer cylinder 3 extends inward by 1-2 cm, which matches the inner outer cylinder of the middle cylinder B6 which contracts inward by 1-2 cm. The two cylinders are nested together to form a space for storing nutrients. When the base layer 38 is sprayed and the middle cylinder B6 is lifted upward, this space is released, and the nutrients fall to the bottom to provide nutrients for the early growth of the plants.

[0069] Preferably, the outer cylinder A3 has an outwardly extending square structure on its outer side, which can be connected to the wooden panel 52 of the planting bag 54 to achieve the connection of nutrients and water. The square structure is fixed to the wooden panel 52 of the planting bag 54 by buckles or rivets.

[0070] Preferably, the second PVC pipe 5 at the center of the middle cylinder B6 is circular at the bottom and square at the top, respectively cooperating with the first PVC pipe 2 of the outer cylinder A3 and the square hollow pipe 10 of the inner cylinder C9 to form an integral air-guiding pipe structure. The air-guiding pipe has holes evenly arranged in the pipe body to increase the oxygen content of the soil in the planting hole 41.

[0071] Preferably, the inner cylinder C9 has a round hole 8 at its top and bottom, which is convenient for workers to lift it upwards during construction. The upper and lower parts of the inner cylinder C9 are made of sawdust material, and the middle part is a compressible area 11 that combines non-woven fabric and loofah sponge. When filling with soil, this area is stretched, so that the inner cylinder C, which is originally smaller than the overall planting hole 41, becomes longer after filling with soil, so that the planting hole 41 can be filled with soil. The material used in the compressible area 11 can effectively absorb water, maximize the reception of nutrients from the planting bag 54, and keep the nutrients in this area to supply plant growth.

[0072] Furthermore, the compression structure is made of water-absorbing material, which can effectively catch the nutrient-rich water from the planting bag 54 and retain the nutrients in the area for easy absorption by the plant growth.

[0073] like Figures 9-16 As shown, the plant bag 54 assembly includes a second inner cylinder 25 and an outer cylinder. The inner and outer surfaces of the second inner cylinder 25 are frosted. Two small cylindrical protrusions 53 are evenly arranged on the outer side of the second inner cylinder 25 and are connected to the second inner cylinder 25 to achieve synchronous rotation. The cylinder is equipped with a telescopic device, which improves the nutrient dissolution rate by extruding and grinding the material. The second inner cylinder 25 and the outer cylinder are equipped with a through round rod that penetrates the plant bag 54. The surface of the through round rod is evenly arranged with holes, which can allow water to flow out after water is injected. An auger 22 and a stirring rod 23 are also arranged. The through round rod can drive the auger 22 and the stirring rod 23 to rotate. The stirring rod 23 is arranged below the feed inlet to initially crush the material, and then the material is transferred to the telescopic devices on both sides for fine grinding by the auger 22.

[0074] Preferably, the top of the vegetation bag 54 assembly is provided with a cover plate 40, which can be lifted upwards to add materials. The cover plate 40 has a buckle structure inside, which can limit the opening range of the cover plate and form a footing platform on the slope, making it convenient for workers to stand on it for work. The cover plate 40 is flush with the surface layer 39, which can provide workers with working space on the slope. The bottom of the vegetation bag inlet panel 7 of the vegetation bag assembly is provided with hooks around its perimeter, which can be combined with galvanized mesh to fix the vegetation bag 54 to the hard slope 37. The hooks and galvanized mesh are connected by buckles or rivets to ensure the stability of the vegetation bag 54 on the hard slope 37.

[0075] Preferably, both ends of the planting bag 54 are equipped with gears, including an external gear 20, an inner cylinder half-wheel 19, and a telescopic device gear 21. The entire planting bag 54 is driven by the inner cylinder half-wheel 19 to rotate the other gears. The external gear 20 and the inner cylinder half-wheel 19 cooperate to make the telescopic device gear 21 rotate alternately counterclockwise and clockwise. Under the alternating rotation of the telescopic device gear 21, the upper baffle 26 is driven to rotate alternately. The upper baffle 26 has an arc-shaped strip structure. Under the alternating rotation of the upper baffle 26, the telescopic rod 28 can extend and retract along the slide groove 27. The extension and retraction of the telescopic rod 28 can squeeze the material against the inner wall and improve the grinding efficiency.

[0076] Preferably, a soft water pipe is installed above the structure of the planting bag 54 to serve as a water storage unit. When the water storage unit on the upper side of the planting bag 54 stores enough water, the water is drained through the water pipe, causing the turbine 31 inside the cylinder 30 to rotate. There are two cylindrical protrusions on the back 5 of the planting bag 54. A turbine 31 with a diameter slightly smaller than the diameter of the cylinder 30 is arranged inside the cylinder 30. When the water flow from the upper part impacts, it can drive the lower turbine 31 to rotate. The lower turbine fan 31 engages with the small cylindrical protrusion 31 on the second inner cylinder 25. The rotation of the turbine will drive the second inner cylinder 25 to rotate, causing the second inner cylinder 25 to rotate and grind. Finally, the nutrient-rich water flows into the planting hole 41.

[0077] Preferably, the planting bags 54 can be connected in series, with each planting bag 54 connected by a rod 49 and a clamping plate 47. The rod 49 is provided with a water outlet 50 to allow water to flow through. The rod 49 and the clamping plate 47 are connected by a snap fastener. After the planting bags are connected in series, each row of planting bags is provided with a motor output inlet 43 at its end, which controls the turbine 31 and the through-tube that passes through the planting bag 54. The output port of the micro motor is placed in it to provide power to drive the water flow and the grinding device. The turbine 44 and the tube are driven by gears to ensure the efficient operation of the water flow and the grinding device.

[0078] Furthermore, the outer shell of the planting bag 54 has an outer panel 33 that can be connected to the planting hole 41, and both ends of the outer shell have gears and three fixed gears 34 to ensure the safe rotation of the second inner cylinder 25.

[0079] Furthermore, there are multiple sets of telescopic devices inside the plant bag 54 structure, which are controlled by a circular tube that runs through the whole structure. While the second inner cylinder 25 rotates, the telescopic structure below unfolds alternately to squeeze the material and the inner wall abrasive structure to increase the grinding efficiency. A stirring rod 23 is arranged in the middle for initial crushing, and then the auger 22 on both sides transports the material to the telescopic structure on both sides for fine grinding.

[0080] Furthermore, the top of the vegetation bag 54 structure can be lifted upwards to add materials for long-term use. After the surface layer 39 is constructed, the cover plate 40 is flush with the surface layer 39 and can be lifted upwards. The cover plate 40 has a buckle structure inside that can limit the opening range of the cover plate 40, providing a footing platform for workers to improve work efficiency during slope construction. Hooks are arranged around the bottom of the vegetation bag inlet panel 54 to combine the vegetation bag device with the galvanized iron mesh.

[0081] Furthermore, the planting bags 54 are connected in series, with rods 49 and interlocking pieces 47 between each pair of planting bags 54. Water outlets 50 are arranged on the rods 49 to allow water to flow through. The circular plates 46 are fixed to both sides of the planting bags 54, so that the rotation of the end drives the rotation of the next bag. A soft thin tube 51 is used to protect the connection to prevent soil from entering and affecting the transmission efficiency.

[0082] Furthermore, after the planting bags 54 are connected in series, they are connected to a water pipe at the end, and a motor output inlet 43, a turbine fan 44 and a lateral gear 45 are arranged there. When the valve 42 is opened, water flows from the water pipe to the planting bags 54, and the micro motor is started. One side drives the turbine fan 44 to increase the water flow rate, and the other side drives the lateral gear 45 to rotate, thereby driving the grinding of the subsequent planting bags 54.

[0083] Example 2:

[0084] like Figures 17-18 As shown, the operation method of the above-mentioned slope restoration system based on the vegetation hole 41 environmentally friendly sleeve includes the following steps:

[0085] S1, Set the planting holes on the hard slope and fill the planting holes with biodegradable sleeve components; Connect the planting bags to the biodegradable sleeve components through wooden panels, and fix them to the hard slope with rivets on the other side; Connect the planting bags in series and protect the connection with hoses, and carry out base spraying work on the hard slope, controlling the height of base spraying to the top of the outer cylinder A.

[0086] S2, fix the galvanized mesh to the hook at the top of the planting bag, then lift the middle cylinder B and carry out the surface spraying operation until the height reaches the top of the middle cylinder B;

[0087] S3, take out the inner cylinder C, turn it over, fill the inner cylinder C with soil and plants, and then place the inner cylinder C into the planting hole;

[0088] S4. After fixing the planting bags and biodegradable sleeve components on the slope, start the water pump to let the water flow into the planting bags through the pipe. Open the valves at the ports of each row of planting bags in sequence, put the output port of the micro motor into the end inlet, start the micro motor, and use the power of the micro motor to drive the water flow into the planting bags and start the grinding device inside the planting bags to work.

[0089] Furthermore, after fixing the planting bags and biodegradable sleeve components to the slope, the water pump below the slope is started to transport water upwards. Then, an electric screwdriver is used to insert the water into the starting point of each planting bag, and the electric screwdriver drives the water flow into the planting bag and starts the grinding device inside the planting bag.

[0090] Example 3:

[0091] This embodiment provides an environmentally friendly sleeve device for the construction of vegetation holes 41 on slopes. It consists of multiple environmentally friendly sleeves connected together, namely sleeve A, sleeve B, and sleeve C. Sleeve A and sleeve B are both made of compressed sawdust material. The interior of sleeve C has a loofah structure, with the upper and lower parts made of compressed sawdust material. The inner and outer layers are bonded together in parallel using plant cellulose adhesive. At the bottom of the outer sleeve A3, there is a conical water collection hopper 4, which is filled with coconut coir. The first two types of materials, hydrophobic material and water storage material, can filter excess water in the vegetation hole 41 to prevent impurities in the water flow from clogging the thin tube below. At the bottom, there is a water storage material to keep a certain amount of water in the hole, which will be discharged when it is higher than the water level in the conduit. The bottom of the outer sleeve A3 extends inward by 1-2 cm. When it is not unfolded, it can be combined with the inward-retracting part of the middle sleeve B6 to form a space for storing nutrients. The height of this space is similar to the height of the surface layer 39. When the base layer 38 is sprayed and the middle sleeve B6 is lifted upward, this space is released, and the nutrients in it fall to the bottom to provide nutrients for the early growth of plants.

[0092] In this invention, the inner cylinder A3 has a groove 27 inside its central tube, and eight orifices are arranged on its outer wall, with four orifices per group. The distance between the upper and lower groups is the height of the surface layer 39. Below the central tube of the middle cylinder B6, there is a controllable telescopic spring 16 structure, which consists of a spring 16 (non-metallic material, such as PVC), an outer buckle, and the groove 27. When not unfolded, this structure is located in the first group of orifices. When the base layer 38 is sprayed, the height of the outer cylinder A3 is used as a reference. When the base layer 38 reaches the top of the outer cylinder A3, the spraying of the base layer 38 is completed. At this time, the inner cylinder C is taken out, and the buckle is pressed and pulled up. When it encounters the second group of orifices, it can automatically extend to fix it. The height of the middle cylinder B6 raised at this time is the thickness of the surface layer 39 to be laid. The worker only needs to lay the surface layer 39 to the top of the middle cylinder B6.

[0093] In this invention, the inner cylinder C9 has a hollow structure at the top and bottom. When spraying the slope, this structure can protect the base layer 38 material and the surface layer 39 material entering the planting hole 41, reducing damage to the planting hole 41. After the surface layer 39 spraying is completed, the inner cylinder C can be removed. The inner cylinder C has gaps at the top and bottom for placing the outer cylinder A3. The crossbar 1 in the middle cylinder B6 has a limiting function. There is a round hole 8 with a diameter of 1.5cm and a depth of more than 3cm at the bottom of the inner cylinder C, which makes it easy for workers to lift by hand. After filling the inside with soil and plants, it is placed in the planting hole 41 without the need for machine spraying again, which can reduce labor costs. After the soil is filled and turned over in the inner cylinder C, the loofah material inside the inner cylinder C and the non-woven fabric in the middle can receive nutrients from the planting bag 54 to supply plant growth.

[0094] In this invention, the hollow tubes at the center of cylinders A, B, and C can be integrated into one unit. The hollow tube is made of a non-degradable material and has holes evenly arranged in its body. While being fixed to the cylinder, the hollow tube can also act as an air duct for the plant after the cylinder is fully opened, increasing the oxygen content of the soil in the planting hole 41.

[0095] Preferably, the plant substrate layer is filled with a plant substrate suitable for plant growth; the components of the plant substrate are as follows by mass: 100 parts of improved bottom mud, 4-6 parts of ecological modifier, 2-3 parts of plant fiber, 2-3 parts of organic material, 3-4 parts of organic fertilizer, 0.15-0.2 parts of long-acting compound fertilizer, and 0.08-0.1 parts of water-retaining agent.

[0096] The improved sediment is dried riverbed sediment obtained by dewatering and passing it through a 2cm sieve, with a water content of <5%.

[0097] Furthermore, the ecological modifier is provided by the Slope Protection and Ecological Restoration Research Center of Three Gorges University and is a product of the transfer of Three Gorges University's patent achievements. The patent publication number for this product is CN 110256149 A. The ecological modifier can, on the one hand, adjust the pH value of the substrate, promote soil activation, maintain moisture and nutrients in the substrate, and promote plant germination and survival; on the other hand, it can improve the physicochemical properties of the substrate, adjust its microstructure, aggregate particle structure, and enhance its freeze-thaw characteristics. In addition, the bacterial agents and microorganisms stored in the ecological modifier can also regulate the microbial characteristics of the substrate, ensuring the continuous circulation and release of nutrients and improving the soil microenvironment.

[0098] The plant fiber used is one or more of corn stalks, cotton stalks, and bamboo fiber. This plant fiber can reinforce the substrate, improve soil structure, increase organic matter content, enhance water and fertilizer retention capacity, and promote microbial activity. It also disperses stress within the soil, reduces stress concentration, minimizes soil deformation, reduces crack width, and inhibits crack development.

[0099] Furthermore, the organic material is one or more mixtures of sugarcane bagasse, rice husks, and sawdust. Initially, the organic material can improve the pore structure of the substrate and enhance its water and air permeability; later, after decomposition, it can provide some nutrients for plant growth.

[0100] Furthermore, the organic matter content of the organic fertilizer is ≥45%. Organic fertilizer: provides nutrients for the initial growth of plants.

[0101] Furthermore, the ratio of nitrogen, phosphorus, and potassium in the long-acting compound fertilizer is 1-2:1-2:2-3.

[0102] Among them, long-acting compound fertilizer: regulates the sustainable supply of nutrients, creating a favorable environment for plant growth. Furthermore,

[0103] The water-retaining agent is a water-absorbing resin with a water absorption ratio greater than 300 times. Specifically, the water-retaining agent enhances the water retention and water holding properties of the substrate.

[0104] In this embodiment, a flexible water pipe is installed above the structure of the planting bag 54 to serve as a water storage unit. The water tank is laid flat between the base layer 38 and the surface layer 39. The water pipe receives the water flow from the planting hole 41 above and can discharge the received water to provide sufficient power for the turbine device below.

[0105] In this embodiment, there are two cylindrical protrusions 30 on the back 5 of the planting bag 54. A turbine 31 with a diameter slightly smaller than the cylinder 30 is arranged inside each cylinder 30. When the upper water flow impacts the cylinder, it drives the lower turbine 31 to rotate. The lower turbine fan 31 engages with a small cylindrical protrusion 31 on the second inner cylinder 25. The rotation of the turbine drives the second inner cylinder 25 to rotate, causing it to grind the water. Finally, nutrient-rich water flows into the planting hole 41.

[0106] In this embodiment, the second inner cylinder 25 of the planting bag 54 structure has multiple sets of telescopic devices that can be located inside the planting bag 54 structure. The three telescopic devices work alternately in a group, and the rotation is controlled by a circular tube that runs through the whole structure. While the second inner cylinder 25 rotates, the telescopic structure below unfolds alternately to squeeze the material so that the material adheres to the abrasive layer of the second inner cylinder 25 for fine grinding and to improve the grinding efficiency. There is a material inlet in the middle upper part, and a stirring rod 23 is arranged below it to perform initial crushing of the material. Then, the auger 22 on both sides transports the material to the telescopic structure on both sides for fine grinding by rotation.

[0107] In this embodiment, the planting bags 54 can be connected in series. A retractable PVC hose protects the transmission device from being blocked by soil between the connections of each planting bag 54. A connecting rod and rotating shaft device at the connection point of each planting bag 54 not only enables power transmission to each independent planting bag but also solves the problem of poor transmission effect caused by uneven interface heights due to construction reasons. At the ends of each row of planting bags, a micro-motor with a switch controls the turbine fan 44 and the lateral gear 45 via the motor output inlet 43, thereby increasing the flow velocity of water into the planting bag and the rotation of the circular tube 24 penetrating the planting bag 54. An electric screwdriver motor can be inserted to provide power; one side of the screwdriver motor drives the turbine 31 to increase the inward water flow velocity, while the other side drives the rotation of the central circular tube.

[0108] In this embodiment, the top of the vegetation bag structure can be lifted upwards to add materials for long-term use. After the surface layer 39 is constructed, the cover plate 40 is flush with the surface layer 39, and the cover plate 40 can be lifted upwards. The cover plate 40 has a buckle structure inside that can limit the opening range of the cover plate 40, providing a foothold platform for workers on the slope. The buckle structure inside can fix the size of the cover plate 40's movement, making it easy for workers to stand on it and work, thus improving the efficiency of workers on the slope. Hooks are arranged around the bottom of the vegetation bag inlet panel 7 to combine the vegetation bag device with the galvanized iron mesh.
