Description

Technical Field

[0001] The invention relates to the field of slope engineering protection and ecological restoration, and in particular to a slope ecological restoration system based on a vegetation hole environmental protection sleeve and an operation method. Background Art

[0002] During the rapid development of social economy, a large number of engineering construction projects have destroyed the original structure of mountain slopes, reduced the stability of slopes, and caused vegetation damage and soil erosion. The existing slope protection and ecological restoration technologies have solved the safety, stability and vegetation restoration problems of conventional slopes (such as soil slopes, soil-rock mixed slopes, and broken soft rock slopes) to a certain extent. However, for hard slopes with difficult habitat conditions, especially complete hard rock slopes and existing artificial hardened slopes (such as concrete slopes and mortar-laid stone slopes), there are still deficiencies in how to achieve the storage and connection of slope water and nutrients and create a sustainable habitat, which leads to low plant survival rate, slow growth, and unsustainable vegetation restoration.

[0003] For example, the authorization announcement number CN222263746U discloses a greening device for mine management, which uses greening planting boxes to fix the soil for planting vegetation, solving the problem of nutrient supply for early plant growth, but lacks consideration for the continuous supply of nutrients and water in the later stage. The authorization announcement number CN118895774B discloses a slope greening device, which creates a habitat through ecological bags and anchoring devices, but does not solve the problem of nutrient and water connectivity in vegetation bags; the authorization announcement number CN219491025U sets planting holes on the surface of a steep and complete rock slope, 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, which is difficult to achieve sustainability.

[0004] Although the above technical solution solves the problem of fixation on steep slopes and hard rock slopes and the supply of nutrients in the early stage of plant growth, it does not consider the connection of nutrients and water and the sustainable supply of nutrients and water in the later stage of ecological restoration, which leads to low plant survival rate, slow growth rate and unsustainable ecological restoration. Therefore, it is necessary to design a slope ecological restoration system and operation method based on a vegetation hole environmental protection sleeve to solve the above problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a slope ecological restoration system and operation method based on a vegetation hole environmental protection sleeve. The solution aims to solve the problems of poor water and nutrient connectivity, unsustainable supply, low plant survival rate and slow growth rate in the prior art. The system is compact and easy to use. The materials used can be naturally degraded to protect the environment and provide nutrients for plant growth. The vegetation hole of the device is connected to the vegetation bag, and the vegetation bag is connected to the external water tank. While ensuring the automatic storage and continuous supply of slope water and nutrients, it can also realize the connection, exchange and regulation of water, nutrients, air and other material energies, thereby improving plant survival rate and promoting plant growth, and thus realizing the sustainability of slope ecological restoration.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: A slope ecological restoration system based on a vegetation hole environmental protection sleeve, comprising a degradable sleeve assembly, the degradable sleeve assembly consisting of an outer cylinder A, a middle cylinder B and an inner cylinder C, the outer cylinder A, the middle cylinder B and the inner cylinder C are nested and connected in sequence; a vegetation bag assembly is connected to the degradable sleeve assembly, and is used to transport nutrients and water to the vegetation hole; the bottom of the outer cylinder A is a conical water collecting bucket, which is filled with coconut bran, hydrophobic material and water-absorbing material, and a circular hollow first PVC pipe is arranged in the center, and the outer wall of the pipe is provided with eight holes, which are divided into two groups, four in each group, for connection with the middle cylinder B and air circulation in the vegetation hole; The middle tube B is a bottomless structure, with a second PVC tube in the center; a telescopic control structure composed of a spring, a support rod and a buckle made of PVC material is arranged inside the middle tube B, and the telescopic control structure is connected to the second PVC tube for controlling telescopic and fixing; a cross bar pressed by sawdust material is connected inside the outer tube A and the middle tube B to fix the first PVC tube and the second PVC tube located in the center of the A tube and the B tube; a track structure is arranged outside the first PVC tube, and the telescopic control structure slides up and down along the track, and the telescopic control structure is pressed by sawdust, wherein the outer protrusion encounters a hole on the first PVC tube and can extend outward for fixing, and a groove is arranged inside the support rod structure, so that the outer protrusion can be retracted inward and slide on the track, and the spring is compressed during the track sliding process, and when the outer protrusion slides to the next hole, the spring is released to expand the outer protrusion; The inner tube C has an open bottom structure, and the inner layer is made of loofah material. There are gaps at the upper and lower parts of the inner tube C around the tube body for placing the cross bars of the outer tube A and the middle tube B, which plays a limiting role. A square hollow tube is arranged in the center of the inner tube C, which can be connected with the first PVC tube and the second PVC tube of the outer tube A and the middle tube B to form an air duct for the plant.

[0007] Furthermore, when laying the base layer, the outer cylinder A can serve as an elevation. When the base layer is laid to the top of the outer cylinder A, it stops. At this time, the spring buckle structure inside the middle cylinder B is pressed. The spring is made of PVC material and can move the middle cylinder B and the inner cylinder C upward to a certain height until the spring buckle structure is clamped again. At this time, the middle cylinder B can provide an elevation, and when the surface layer is laid to the top of the middle cylinder B, it stops.

[0008] Furthermore, when the surface layer construction reaches the height of the middle tube B, the surface layer spraying stops, the inner tube C can be pulled upward and filled with soil and plants inside, then the upper bottom is converted to the lower bottom, and the inwardly curved loofah layer is fully unfolded and loaded into the vegetation hole; the sawdust material on the lower side of the middle tube B is relatively fragile, and when the inner tube C is filled with soil and placed in the middle tube B, the raised structure below the middle tube B can be destroyed to ensure that the vegetation hole is filled with soil.

[0009] Preferably, the bottom of the outer tube 3 extends inward by 1-2 cm, and cooperates with the outer tube below the middle tube B to shrink inward by 1-2 cm. The two tubes are nested to form a space for storing nutrients. When the base layer is sprayed, the middle tube B is lifted upward, and the space is released, and the nutrients in it fall to the bottom, providing nutrients for the early growth of plants.

[0010] Preferably, the outer side of the outer tube A is provided with an outwardly extending square structure, which can be connected to the wooden panel of the vegetation bag to achieve the connection of nutrients and water. The square structure is fixed to the wooden panel of the vegetation bag by buckles or rivets.

[0011] Preferably, the second PVC tube in the center of the middle tube B is circular at the bottom and square at the top, and respectively cooperates with the first PVC tube of the outer tube A and the square hollow tube of the inner tube C to form an integral air guide tube structure. The air guide tube has holes evenly arranged on the tube body to increase the oxygen content in the soil in the vegetation hole.

[0012] Preferably, a circular hole is arranged at the upper bottom of the inner tube C to facilitate workers to extract upwards during construction. The upper and lower parts of the inner tube C are pressed from sawdust material, and the middle part is a compressible area combining non-woven fabric and loofah pulp. When filling with soil, this area is stretched so that the C tube, which was originally smaller than the overall vegetation hole, becomes longer after filling with soil so that the vegetation hole can be filled with soil. The material used in the compressible area can effectively absorb water to maximize the nutrients from the vegetation bag and keep the nutrients in the area to provide for plant growth.

[0013] Furthermore, the compression structure is made of a water-absorbing material, which can effectively receive the nutrient-rich water from the planting bag and retain the nutrients in the area for easy absorption by the growing plants.

There is a snap-on structure inside the cover plate, which can limit the opening range of the cover plate and provide a foothold for workers on the construction site to facilitate their work on the slope. When the cover plate is closed, it is flush with the surface layer, providing a working space for workers on the slope. Hooks are arranged around the bottom of the wooden panel of the vegetation bag assembly of the vegetation bag feed port railing, which can be combined with a galvanized mesh to fix the vegetation bag to the hard slope. The hooks are connected to the galvanized mesh by snaps or rivets to ensure the stability of the vegetation bag on the hard slope.

[0015] Furthermore, hooks are arranged around the bottom of the vegetation bag feed port railing to fix the movable 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, providing working space for workers on the slope.

[0016] Preferably, gears are arranged at both ends of the vegetation bag, including an outer gear, an inner cylinder half wheel and a telescopic device gear. The entire vegetation bag is rotated by the inner cylinder half wheel driving other gears. The outer gear cooperates with the inner cylinder half wheel to make the gear of the telescopic device 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 is an arc-shaped strip structure. Under the alternating rotation of the upper baffle, the telescopic rod can be telescoped back and forth along the slide groove. The telescopic movement of the telescopic rod can squeeze the material and the inner wall, thereby improving the grinding efficiency.

[0017] Preferably, a soft water pipe is arranged above the vegetation bag structure to serve as a water storage unit. When the water storage unit on the upper side of the vegetation bag stores enough water, the water is drained through the water pipe to rotate the turbine fan inside the cylinder. There are two cylinders with cylindrical protrusions on the back of the vegetation bag. A turbine structure with a diameter slightly smaller than the diameter of the cylinder is arranged inside the cylinder. There is a rotor. When the upper water flow impacts, it can drive the turbine below to rotate. The turbine fan below can engage with the small cylindrical protrusion cylinder on the inner cylinder to rotate the inner cylinder for grinding, and finally the nutrient-rich water flows into the vegetation bag again.

[0018] Preferably, the vegetation bag assemblies can be connected in series, and each vegetation bag is connected by a rod and a bite piece. A water outlet is arranged on the rod to realize the penetration of water flow. The rod and the bite piece are connected by a snap buckle to ensure that the connection between each vegetation bag is firm and the water flow is smooth; the first section structure of the vegetation bag assembly is provided with a motor output inlet, which respectively controls the turbine wheel and the circular tube passing through the vegetation bag, and a micro motor is placed therein to provide power to drive the water flow and the grinding device to work. The turbine wheel and the circular tube are driven by gears to ensure the efficient operation of the water flow and the grinding device.

[0019] Furthermore, the vegetation bag structures are connected in series, and each vegetation bag structure consists of three rotating rods to prevent transmission problems caused by inconsistent heights of the vegetation bags during actual construction. A motor output inlet is provided at the end of each row of vegetation bags, and the interior of the inlet controls the turbine wheel and the circular tube penetrating the vegetation bag respectively. Workers can start the micro motor to rotate the turbofan and the lateral gear. The rotation of the turbofan can increase the flow rate of water in the water pipe, and the lateral gear can drive the circular tube penetrating the vegetation bag to provide power for the grinding device of the vegetation bag. Workers can put an electric screwdriver motor into it to provide power. The turbine wheel can increase the flow rate of the inward water flow and control the rotation of the circular tube.

[0020] Furthermore, an outer panel is provided on the outer shell of the vegetation bag which can be connected with the vegetation hole, and both sections of the outer shell are provided with gears and three fixed gears, which can ensure the safe rotation of the inner cylinder.

[0021] Furthermore, there are multiple groups of telescopic devices inside the vegetation bag structure, and the rotation is controlled by a round tube that runs through the whole bag. While the inner tube of the structure rotates, the telescopic structure below is alternately expanded to squeeze the material and the inner wall grinding structure to improve the grinding efficiency. A stirring rod is arranged in the middle for primary crushing, and then the auger devices on both sides transport the material to the telescopic structures on both sides for fine grinding.

[0022] Furthermore, the top of the cover of the vegetation bag structure can be lifted up to add materials for long-term use. When not opened, the cover is flush with the surface layer. The cover can be lifted up, and there is a snap-fit ​​structure inside the cover to limit the opening range of the cover, providing a foothold for workers working on the slope, which is convenient for workers to construct. When the cover is closed, it is flush with the surface layer; hooks are arranged around the bottom of the vegetation bag feed port railing, and there is a snap-fit ​​structure inside the cover to fix the movable size of the cover to provide working space for workers; hooks are arranged around the square bottom of the vegetation tube to be fixed in combination with the galvanized mesh.

[0023] Furthermore, the vegetation bags are connected in series, with rods and bite plates between each pair of vegetation bags. Water outlets are arranged on the rods to achieve water flow, and then circular plates are fixed on both sides of the vegetation bags to achieve rotation of the end to drive the next rotation. The connection is protected by a soft thin tube to prevent soil from entering and affecting the transmission efficiency.

[0024] Furthermore, after the vegetation bags are connected in series, they are connected to the water pipe at the end, and are provided with an inlet of a micro motor, a turbofan and a lateral gear. When the valve is opened, water flows from the water pipe to the vegetation bag. The output port of the micro motor is placed in the inlet of the end, and the micro motor is started and the electric screwdriver is inserted into the screwdriver inlet for rotation. One side drives the turbofan to increase the water flow rate, and the other side drives the lateral gear to rotate, thereby driving the grinding of the penetrating circular hole and the subsequent vegetation bag.

[0025] Preferably, the operation method of the slope ecological restoration system based on the vegetation hole environmental protection sleeve comprises the following steps: S1, setting a planting hole on a hard slope, filling the planting hole with a degradable sleeve assembly; connecting the planting bag to the degradable sleeve assembly through a wooden panel, and fixing the other side to the hard slope with rivets; connecting the planting bags in series and protecting the connection with a hose, spraying the base layer on the hard slope, and controlling the height of the base layer spraying to be at the top of the outer cylinder A; S2, fix the galvanized mesh to the hook on the upper part of the planting bag, then lift the middle tube B, and perform the surface spraying operation until the height reaches the top of the middle tube B; S3, taking out the C tube, turning it over, filling the inside of the C tube with soil and plants, and then placing the C tube in the planting hole; S4, after fixing the vegetation bag and the degradable sleeve assembly on the slope, start the water pump to let water flow into the vegetation bag through the pipe, open the valves at the ports of each row of vegetation bags in turn, 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 vegetation bag and start the grinding device inside the vegetation bag to work.

[0026] Furthermore, after the vegetation bags and the degradable sleeve assembly are fixed on the slope, the water pump under the slope is started to transmit water upward, and then an electric screwdriver is inserted into the starting point of each vegetation bag. The electric screwdriver is used to drive the water flow into the vegetation bag and start the grinding device inside the vegetation bag to work.

[0027] The beneficial effects of the present invention are: 1. The plant fibers of the sponge gourd layer and the sawdust layer are bonded to form a cup-walled (cylindrical) sleeve structure that fits the planting hole. The construction operation is convenient, and the extrusion force generated by the filling of the base material in the sleeve and the expansion force generated by the swelling of the sponge gourd layer when it encounters water continuously squeeze the hole wall, while fixing the sleeve, the overall stability of the slope is improved. At the same time, the degradation and utilization of the sawdust layer provides a source of nutrition for the plant in the later stage. The implementation of the present invention is conducive to the outward seepage of excess water in the planting hole, reducing the root rot of the plant caused by excessive water in the hole, and when the base material is in a water-deficient state, the water-absorbing material and the sleeve can absorb and store part of the water to alleviate the water shortage of the plant.

[0028] 2. The sleeve structure of the vegetation hole of the present invention can provide elevation indication for workers during spraying. The base layer and the surface layer are laid to a certain height and then stopped. During the spraying of the base layer and the surface layer, the vegetation hole is in a closed state. After the surface layer construction is completed, the soil filled in the cylinder is turned over to prevent the sprayed material from entering the vegetation hole during the spraying operation. The machine and labor costs are reduced when the inner cylinder C is filled with soil and turned over to put into the vegetation hole.

[0029] 3. The present invention provides nutrients in the vegetation 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 world. Water with nutrients from the outside flows into the vegetation hole. The non-woven fabric and loofah in the inner tube C closest to the plant can take on most of the nutrients to supply the plant, thereby improving the survival rate of plants at all stages.

[0030] 4. The vegetation bag structure of the present invention arranges the opening on the surface layer so that it can be added and supplemented according to the material usage, thereby realizing long-term maintenance of ecological restoration. In addition, the opening plate can limit the opening range, providing a standing point for workers working on the slope, ensuring the safety of the workers and improving work efficiency.

[0031] 5. The vegetation bag structure of the present invention can be ground autonomously by water flow in an unmanned state, and the water flow containing nutrients can be directed to the vegetation holes. Workers can also use a handheld screwdriver drill to provide power to introduce external water sources for irrigation, which reduces the investment in labor costs. The water flow inside the pipeline is sent into the vegetation holes through the pump body, which reduces water evaporation and improves water utilization.

[0032] 6. The present invention can autonomously impact the turbine located at the back of the vegetation bag through the accumulated water, and the kinetic energy of the downward flow of water can rotate the turbine and the turbine fan, thereby driving the rotation of the inner tube of the vegetation bag to start the grinding device inside the vegetation bag and guide the water containing nutrients to the vegetation hole. The number of grinding and irrigation of plants in the vegetation hole can also be increased manually. The worker starts the water pump and the micro motor at the end of the vegetation bag to drive the water flow in and the start of the grinding device, which reduces the investment in labor costs and sends the water flow in the pipeline into the vegetation hole through the pump body, reducing water evaporation and improving water utilization rate.

DETAILED DESCRIPTION

[0034] Embodiment 1: like Figure 1~Figure 3As shown, a slope ecological restoration system based on an environmentally friendly sleeve of a vegetation hole 41 includes a degradable sleeve assembly, which is composed of an outer cylinder A3, a middle cylinder B6 and an inner cylinder 25C9, and the outer cylinder A3, the middle cylinder B6 and the inner cylinder 25C9 are nested and connected in sequence; the vegetation bag 54 assembly is connected to the degradable sleeve assembly for transporting nutrients and water to the vegetation hole 41.

[0035] like Figure 4 As shown, the bottom of the outer cylinder A3 is a conical water collecting bucket 4, which is filled with coconut bran, hydrophobic material and absorbent material. A circular hollow first PVC tube 2 is arranged in the center. The outer wall of the tube is provided with eight holes, which are divided into two groups, four in each group, for connection with the middle cylinder B6 and air circulation in the vegetation hole 41.

[0036] like Figure 5 As shown, the middle tube B6 is a bottomless structure, with a second PVC tube 5 arranged in the center; a telescopic control structure composed of a spring 16 of PVC material, a support rod 15 and a buckle is arranged inside the middle tube B6, and the telescopic control structure is connected to the second PVC tube 5 for controlling telescopic and fixing; a cross bar 1 pressed by sawdust material is connected inside the outer tube A3 and the middle tube B6 to fix the first PVC tube 2 and the second PVC tube 5 located at the center of the A tube and the B tube; a track 13 structure is arranged outside the first PVC tube 2, and the telescopic control structure slides up and down along the track 13, and the telescopic control structure is pressed by sawdust, wherein the outer protrusion 14 encounters a hole on the first PVC tube 2 and can extend outward for fixing, and a groove is provided in the support rod 15 structure to realize the outer protrusion 14 to be retracted inward and slide on the track 13, and the spring 16 is compressed during the sliding process of the track 13, and when the outer protrusion 14 slides to the next hole, the spring 16 is released to expand the outer protrusion 14.

[0037] like Figure 6~Figure 8 As shown, the inner tube 25C9 is a bottom-opening structure, and the inner layer is made of loofah material. The inner tube 25C9 has gaps at the upper and lower parts around the tube body for placing the cross bars 1 of the outer tube A3 and the middle tube B6, which plays a limiting role; a square hollow tube 10 is arranged in the center of the inner tube 25C9, which can be connected with the first PVC tube 2 and the second PVC tube 5 of the outer tube A3 and the middle tube B6 to form an air duct for the plant.

[0038] Furthermore, when laying the base layer 38, the outer cylinder A3 can serve as an elevation. When the base layer 38 is laid to the top of the outer cylinder A3, it 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 move the middle cylinder B6 and the inner cylinder 25C9 upward to a certain height until the spring 16 buckle structure is clamped again. At this time, the middle cylinder B6 can provide an elevation. When the surface layer 39 is laid to the top of the middle cylinder B6, it stops.

[0039] Furthermore, when the construction of the surface layer 39 reaches the height of the middle tube B6, the surface layer 39 stops spraying, and the inner tube 25C9 can be pulled upward and filled with soil and plants inside. At this time, the upper bottom is converted to the lower bottom, and the inwardly curved loofah layer is fully unfolded and loaded into the vegetation hole 41; the sawdust material on the lower side of the middle tube B6 is relatively fragile. When the inner tube 25C9 is loaded with soil and placed in the middle tube B6, the raised structure below the middle tube B6 can be destroyed to ensure that the vegetation hole 41 is filled with soil.

[0040] Preferably, the bottom of the outer tube 3 extends inward by 1~2 cm, and cooperates with the outer tube below the middle tube B6 to shrink inward by 1~2 cm. The two tubes are nested to form a space for storing nutrients. When the base layer 38 is sprayed, the middle tube B6 is lifted upward, and the space is released, and the nutrients in it fall to the bottom, providing nutrients for the early growth of plants.

[0041] Preferably, the outer side of the outer tube A3 is provided with an outwardly extending square structure, which can be connected to the wooden panel 52 of the vegetation bag 54 to achieve the connection of nutrients and water. The square structure is fixed to the wooden panel 52 of the vegetation bag 54 by buckles or rivets.

[0042] Preferably, the second PVC tube 5 in the center of the middle tube B6 is circular at the bottom and square at the top, and respectively cooperates with the first PVC tube 2 of the outer tube A3 and the square hollow tube 10 of the inner tube 25C9 to form an integral air guide tube structure. The air guide tube has holes evenly arranged on the tube body to increase the oxygen content in the soil in the vegetation hole 41.

[0043] Preferably, a circular hole 8 is arranged at the upper bottom of the inner tube 25C9 to facilitate workers to extract upwards during construction. The upper and lower parts of the inner tube 25C9 are pressed from sawdust material, and the middle part is a compressible area 11 combining non-woven fabric and loofah pulp. When filling with soil, this area is stretched so that the C tube, which was originally smaller than the overall vegetation hole 41, becomes longer after filling with soil so that the vegetation hole 41 can be filled with soil. The material used in the compressible area 11 can effectively absorb water to maximize the nutrients from the vegetation bag 54 and keep the nutrients in the area to provide for plant growth.

[0044] Furthermore, the compression structure is made of a water-absorbing material, which can effectively receive the nutrient-rich water from the vegetation bag 54 and retain the nutrients in the area for easy absorption by plant growth.

[0045] like Figure 9~Figure 16As shown, the vegetation bag 54 assembly includes an inner cylinder 25 and an outer cylinder. Both the inner and outer surfaces of the inner cylinder 25 are frosted. Two small cylindrical protrusions 53 are evenly arranged on the outer side of the inner cylinder 25 and are connected to the inner cylinder 25 as a whole to achieve synchronous rotation. A telescopic device is provided inside the cylinder to improve the nutrient dissolution rate by squeezing the material for grinding; a penetrating round rod that penetrates the vegetation bag 54 is provided in the center of the inner cylinder 25 and the outer cylinder, and holes are evenly arranged on the surface of the penetrating round rod, so that water can flow out after water is injected, and an auger 22 and a stirring rod 23 are also arranged, and the penetrating round rod can drive the auger 22 and the stirring rod 23 to rotate; the stirring rod 23 is arranged below the feed port to initially crush the material, and then the material is transmitted to the telescopic devices on both sides through the auger 22 for fine grinding.

[0046] Preferably, a cover plate 40 is provided on the top of the vegetation bag 54 assembly, which can be lifted up to add materials. A snap-fit ​​structure is provided inside the cover plate 40, which can limit the opening range of the cover plate and form a footing platform on the slope for workers to step on and work. The cover plate 40 is flush with the surface layer 39, which can provide a working space for workers on the slope; hooks are arranged around the bottom of the vegetation bag feed port guardrail 7 of the vegetation bag 54 assembly, which can be combined with a galvanized mesh to fix the vegetation bag 54 to the hard slope 37. The hooks are connected to the galvanized mesh by snaps or rivets to ensure the stability of the vegetation bag 54 on the hard slope 37.

[0047] Preferably, gears are arranged at both ends of the vegetation bag 54, including an outer gear 20, an inner cylinder 25 half wheel 19 and a telescopic device gear 21. The entire vegetation bag 54 is driven by the inner cylinder 25 half wheel 19 to drive other gears to rotate. The outer gear 20 cooperates with the inner cylinder 25 half wheel 19 to make the gear of the telescopic device rotate alternately counterclockwise and clockwise. Under the alternating rotation of the telescopic device gear 21, the upper baffle plate 26 is driven to rotate alternately. The upper baffle plate 26 is an arc-shaped strip structure. Under the alternating rotation of the upper baffle plate 26, the telescopic rod 28 can be telescoped back and forth along the slide groove 27. The telescopic movement of the telescopic rod 28 can squeeze the material and the inner wall, thereby improving the grinding efficiency.

[0048] Preferably, a soft water pipe is arranged above the vegetation bag 54 structure to serve as a water storage unit. When the water storage unit on the upper side of the vegetation bag 54 stores enough water and then drains the water through the water pipe, the turbine 31 inside the cylinder 30 rotates. There are two cylindrical protrusions on the back 5 of the vegetation bag 54. A turbine 31 with a diameter slightly smaller than that of the cylinder 30 is arranged inside the cylinder 30. When the upper water flow impacts, it can drive the lower turbine 31 to rotate. The lower turbine fan 31 engages with the small cylindrical protrusion 31 on the inner cylinder 25. The rotation of the turbine will drive the inner cylinder 25 to rotate, causing the inner cylinder 25 to rotate for grinding, and finally the nutrient-rich water will flow into the vegetation hole 41.

[0051] Furthermore, there are multiple groups of telescopic devices inside the vegetation bag 54 structure, and the rotation is controlled by a round tube that runs through the whole. While the inner cylinder 25 of the structure rotates, the telescopic structure below is alternately expanded to squeeze the material and the inner wall grinding structure to increase the grinding efficiency. A stirring rod 23 is arranged in the middle for primary crushing, and then the auger 22 devices on both sides transport the material to the telescopic structures on both sides for fine grinding.

[0056] Furthermore, after the vegetation bags and the degradable sleeve assembly are fixed on the slope, the water pump under the slope is started to transmit water upward, and then an electric screwdriver is inserted into the starting point of each vegetation bag. The electric screwdriver is used to drive the water flow into the vegetation bag and start the grinding device inside the vegetation bag to work.

[0057] Embodiment three: The present embodiment provides an environmentally friendly sleeve device for the construction of slope vegetation holes 41, which is connected by multiple environmentally friendly sleeves, namely, tube A, tube B, and tube C. Tube A and tube B are both compressed from sawdust materials. The interior of tube C is a loofah structure, and the upper and lower parts are compressed from sawdust materials. The inner and outer layers are bonded in parallel with plant cellulose adhesive. There is a conical water collecting bucket 4 at the bottom of the outer tube A3, which is filled with coconut bran. The first two types of materials, hydrophobic materials and water storage materials, can filter excess water in the vegetation hole 41 to prevent impurities in the water flow from clogging the capillary below. The water storage material at the bottom retains a certain amount of water for the hole, and the water level above the catheter will be discharged. The bottom of the outer tube A3 extends inward by 1-2 cm, and in the unexpanded stage, it can be combined with the part of the middle tube B6 that shrinks inward to form a space for storing nutrients. The height of the space is close to the height of the surface layer 39. When the base layer 38 is sprayed and the middle tube B6 is lifted upward, the space is released, and the nutrients in it fall to the bottom to provide nutrients for the early plant growth.

[0058] In the present invention, a slide groove 27 is arranged inside the central circular tube of the outer cylinder A3, and eight holes are arranged on the outer wall, with four holes in each group. The distance between the upper and lower groups is the height of the surface layer 39. A controllable retractable spring 16 structure is arranged below the central tube of the middle cylinder B6, which is composed of a spring 16 (non-metallic material can be PVC material), an external buckle, and a slide groove 27. When not deployed, the structure is located in the first group of holes. 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, the buckle is pressed and pulled up, and it can automatically extend out for fixation when it encounters the second group of holes. At this time, the height of the raised middle cylinder B6 is the thickness of the surface layer 39 to be laid, and the worker only needs to lay the surface layer 39 to the top of the middle cylinder B6.

[0059] In the present invention, the inner cylinder C9 is a structure in which the top and bottom are hollow. When the slope is sprayed, the structure can protect the base layer 38 material and the surface layer 39 material from entering the vegetation hole 41, thereby reducing damage to the vegetation hole 41. After the surface layer 39 spraying operation is completed, the inner cylinder C can be taken out. There are gaps above and below the inner cylinder C for placing the outer cylinder A3. The cross bar 1 in the middle cylinder B6 has a limiting function. There is a circular hole 8 with a diameter of 1.5 cm and a depth of more than 3 cm on the bottom of the inner cylinder C, which is convenient for workers to extract by hand. After filling the inner cylinder with soil and plants, it is placed in the vegetation hole 41 without the need for machine spraying again, which can reduce labor costs. After the inner cylinder C is filled with soil and turned over, the loofah material inside the inner cylinder C and the non-woven fabric in the middle can receive nutrients from the vegetation bag 9 to supply plant growth.

[0060] In the present invention, the empty tube in the center of the tubes A, B, and C can be integrated into one. The material of the empty tube is a non-degradable material, and holes are evenly arranged in the tube body. The empty tube can serve as an air duct for the plant after the tube is fully opened while being fixed to the tube, thereby increasing the oxygen content of the soil in the planting hole 41.

[0061] Preferably, the vegetation substrate layer is filled with a vegetation substrate suitable for plant growth; the components of the vegetation substrate are calculated by weight: 100 parts of improved sediment, 4-6 parts of ecological modification agent, 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.

[0062] The improved sediment is dry riverbed sediment obtained by dehydration and passing through a 2 cm sieve, and its water content is less than 5%.

[0063] Furthermore, the ecological modification agent is provided by the Slope Protection and Ecological Restoration Research Center of Three Gorges University, and is a patent transfer product of Three Gorges University, and the patent publication number of this product is: CN 110256149 A. Among them, the ecological modification agent: on the one hand, can adjust the pH value of the substrate, promote the activation of the substrate soil, maintain the moisture and nutrients of the substrate, and promote the germination and survival of plants; on the other hand, it can improve the physical and chemical properties of the substrate, adjust the microstructure of the substrate, aggregate the particle structure, and enhance the freeze-thaw characteristics of the substrate. In addition, the bacterial agents and microorganisms stored in the ecological modification agent can also adjust the characteristics of the substrate microorganisms, ensure the continuous circulation and release of nutrients, and improve the microenvironment of the soil.

[0064] The plant fiber is a mixture of one or more of corn straw, cotton straw and bamboo fiber, wherein the plant fiber can play a reinforcing role on the base material, improve the soil structure, increase the organic matter content, enhance the water and fertilizer retention capacity, and promote microbial activity. It disperses the stress in the soil, reduces stress concentration, reduces soil deformation, reduces the crack width and inhibits the development of cracks.

[0065] Furthermore, the organic material is a mixture of one or more of bagasse, rice husk and sawdust. The organic material can improve the pore structure of the substrate in the early stage, improve the water and air permeability of the substrate, and provide some nutrients for plant growth after humus decomposition in the later stage.

[0066] Furthermore, the organic matter content of the organic fertilizer is ≥45%. Organic fertilizer: provides nutrients for the initial growth of plants.

[0067] Furthermore, the ratio of nitrogen, phosphorus and potassium in the long-acting compound fertilizer is 1-2:1-2:2-3.

The water retaining agent is a water absorbing resin, and the water absorption multiple is greater than 300 times. The water retaining agent: enhances the water holding and water retention of the substrate.

[0069] In this embodiment, a soft water pipe is provided above the vegetation bag 54 structure 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 hose receives the water flow from the vegetation hole 41 above. The water hose can discharge the received water to provide sufficient power for the turbine device below.

[0070] In this embodiment, there are two cylindrical protrusions of the cylinder 30 on the back 5 of the vegetation bag 54. A turbine 31 with a diameter slightly smaller than the diameter of the cylinder 30 is arranged in the cylinder 30. When the upper water flow impacts, it can drive the lower turbine 31 to rotate. The lower turbine fan 31 engages with the small cylindrical protrusion 31 on the inner cylinder 25. The rotation of the turbine drives the inner cylinder 25 to rotate, causing the inner cylinder 25 to rotate and grind, and finally the nutrient-rich water flows into the vegetation hole 41. In this embodiment, there are multiple groups of telescopic devices in the inner cylinder 25 of the vegetation bag 54 structure. The telescopic devices are arranged in groups of three and rotate alternately. The rotation is controlled by a round tube that runs through the whole structure. While the inner cylinder 25 of the structure rotates, the telescopic structure below is alternately expanded to squeeze the material so that the material fits the frosted layer of the inner cylinder 25 for fine grinding to improve the grinding efficiency. There is a material feed port in the upper middle part and a stirring rod 23 is arranged below it to perform initial crushing on the material. The auger 22 devices on both sides then rotate to transport the material to the telescopic structures on both sides for fine grinding.

[0071] In this embodiment, the vegetation bag 54 structure can be connected in series, and a retractable PVC hose is provided between the connections of each vegetation bag 54 to protect its transmission device from being stuck by the soil. A connecting rod rotating shaft device is provided at the connection of each vegetation bag 54. In the process of realizing the power transmission of each independent vegetation bag, the transmission effect caused by the two interfaces being not on the same horizontal line due to construction reasons can also be solved. At the end of each row of vegetation bags, the micro motor is switched on and off, and the motor output inlet 43 controls the turbofan 44 and the lateral gear 45 respectively, thereby increasing the flow rate of the water flowing into the vegetation bag and the rotation of the round tube 24 passing through the vegetation bag 54. The worker can put an electric screwdriver motor into it to provide power. One side of the screwdriver motor drives the vortex turbine 31 to increase the flow rate of the inward water flow, and the other side drives the rotation of the central round tube.
