Description

Technical Field

[0001] This invention relates to the field of slope restoration technology, specifically to an ecological blanket for slope revegetation and a revegetation method. Background Technology

[0002] With increasing awareness of ecological and environmental protection, slope revegetation has become an important ecological project. Traditional slope protection methods, such as concrete slope protection, are not only expensive but also have poor ecological effects and are difficult to integrate with the surrounding environment. Therefore, ecological revegetation blankets for slopes have emerged as a new type of environmentally friendly and economical slope protection material.

[0003] There are various types of ecological blankets for slope revegetation, such as vegetation blankets, slope protection ecological blankets, and plant fiber blankets. These ecological blankets are usually made of natural plant fibers (such as coconut fiber, straw, etc.), geotextiles, grass seeds (optional), and nutrients. Their structure is generally multi-layered, including a net layer, a fiber layer, a seed-vegetated layer (such as with grass seeds), and a bottom net.

[0004] However, the slope protection effect of ecological carpets depends on the growth and reproduction of plant roots. Plants have a long growth cycle and require time to form a dense vegetation layer, so they cannot be effective in a short period. Furthermore, since ecological carpets are laid directly on the slope, it's impossible to ensure a tight bond between the carpet and the slope surface during installation. This restricts root growth and fails to achieve the desired slope protection. Moreover, during the vegetation formation process, rainfall can easily cause soil erosion beneath the ecological carpet, further exacerbating the separation between the carpet and the slope, preventing plants from taking root. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an ecological blanket for slope revegetation and a revegetation method, which solves the problem that the ecological blanket is not firmly fixed to the slope surface in existing technologies, and even causes soil erosion that prevents plants from growing on the slope.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention discloses an ecological blanket for slope revegetation. The ecological blanket consists of a reinforcement layer, a water storage layer, a matrix layer and a surface layer from bottom to top. The ecological blanket is fixed by wrapping with a wire mesh. The thickness of the water storage layer and the matrix layer is 1-3 cm. The ecological blanket is made and cut using an ecological blanket making device.

[0010] Preferably, the ecological blanket making device includes a making groove with a top opening. An adjusting plate is vertically arranged on one side of the making groove along its length. An adjusting rod is rotatably connected to one side of the adjusting plate. One end of the adjusting rod extends out of the side wall of the making groove. A positioning strip is arranged in the making groove and the area enclosed by the making groove and the adjusting plate. Several positioning posts are arranged through the positioning strip. A pressing strip is fixed above the positioning strip through the positioning posts. The positioning strip and the pressing strip press and fix the edge of the ecological blanket.

[0011] Preferably, the positioning post is a tube open at both ends, and a baffle is provided on one end of the positioning post in the circumferential direction. Multiple frustum-shaped locking platforms are provided equidistantly along the axial direction of the positioning post in the circumferential direction. The large diameter end of the locking platform is facing the baffle. The positioning post passes through the bottom of the positioning strip so that the baffle contacts the positioning strip.

[0012] Preferably, after the positioning strip and the clamping strip are fixed, a fixing pile is inserted from the top of the positioning column, and a pressure plate is provided on the top of the fixing pile. Multiple frustum-shaped limiting platforms are equidistantly arranged on the circumference of the fixing pile along its axial direction, and the large diameter end of the limiting platform faces the pressure plate.

[0013] Preferably, the top of the manufacturing groove is provided with parallel slide rails along its width direction, a slider is provided on the slide rail, a guide rod is provided between two sliders, a sliding sleeve is provided on the guide rod, a support plate is provided on both sides of the sliding sleeve, a loading groove is provided on the sliding sleeve and the support plate, an arched groove adapted to the sliding sleeve is provided at the bottom of the loading groove, and a discharge pipe is provided on at least one side of the loading groove, the discharge pipe is oriented towards the width direction of the manufacturing groove.

[0014] Preferably, the loading trough is provided with a guide plate that is inclined toward the connection between the feeding pipe and the loading trough. When the feeding pipe is located on both sides of the loading trough, the guide plate is in the shape of "∧". The guide plate is provided with a notch to accommodate the arch groove.

[0015] Preferably, telescopic members are provided on both sides of the sliding sleeve, below the support plate, and the other end of the telescopic members extends to the top of the groove and the top of the adjustment plate, respectively, and a roller is provided at the bottom.

[0016] And / or, two spacer bars perpendicular to the positioning bars are arranged side by side between adjacent positioning bars in the length direction of the groove, and positioning posts are also provided on the spacer bars; two positioning posts are respectively provided on the positioning bars and near the ends of the spacer bars.

[0017] Correspondingly, one method for revegetating slopes involves soaking the aforementioned ecological blanket in water, ensuring the water depth does not exceed the water storage layer. After the water storage layer has absorbed the water, the ecological blanket is maintained for 1-2 months. Then, a trench is dug on the slope requiring revegetation, the ecological blanket is placed in the trench, and the ecological blanket is fixed in the trench using anchoring stakes.

[0018] The present invention has the following beneficial effects:

[0019] This invention utilizes materials in varying proportions to create a water-retaining layer, which, combined with a plant fiber blanket, maximizes moisture retention to support plant growth. Simultaneously, an ecological blanket manufacturing device allows for the production of ecological blankets of different sizes to meet diverse needs. This invention employs a method of pre-cultivating the ecological blanket, allowing plants to grow before laying it on the slope, thereby increasing the survival rate of plants on the ecological blanket and the degree of revegetation. During the ecological blanket manufacturing process, positioning strips, positioning posts, and clamping strips are used to fix the edges of the ecological blanket. When laying the ecological blanket, fixing stakes are used to secure it to the slope surface, effectively fixing the ecological blanket, strengthening the contact between the ecological blanket and the slope, increasing the fixation strength, and solving the problem of loose fixation between the ecological blanket and the slope surface.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Unless otherwise specified, the technical means used in the implementation examples are conventional means well known to those skilled in the art.

[0030] This invention discloses an ecological blanket for slope revegetation. The ecological blanket comprises, from bottom to top, a reinforcement layer, a water-retaining layer, a matrix layer, and a surface layer. The ecological blanket is secured by a wire mesh. The thickness of the water-retaining layer and the matrix layer are both 1-3 cm. The ecological blanket is manufactured using an ecological blanket manufacturing device and cut to the required size. To prevent leakage of the water-retaining layer and matrix layer after cutting, the perimeter of the ecological blanket is sealed and secured. The manufacturing device disclosed in this invention can secure the perimeter of the ecological blanket and can produce different sizes to meet various needs. The wire mesh is made of straw fiber.

[0031] Furthermore, the reinforcement layer is a plant fiber blanket, which can absorb and retain water, maintain soil stability, and also strengthen and fix the water storage layer to prevent leakage from the mesh of the wire mesh. The surface layer is Selaginella tamariscina, specifically a mat-shaped Selaginella tamariscina with divided plants, which is laid on the substrate layer. The size of the ecological blanket is 30×30cm, and the number of mat-shaped Selaginella tamariscina plants is set at 1 to 3. The water storage layer includes sponge, diatomaceous earth, vermiculite, perlite, sawdust, polyacrylate superabsorbent resin, cellulose, carrageenan, and potassium alginate. The substrate layer includes garden soil, peat moss, mixed gibberellin solution, and organic fertilizer. Organic fertilizer can be locally composted brewer's lees, straw, etc. Native plant seeds are mixed into the substrate layer. The amount of seeds, organic fertilizer, and mixed gibberellin solution can be selected according to the prescribed dosage. Finally, the water storage layer and the substrate layer are mixed evenly and then laid on the plant fiber blanket, which is placed on the wire mesh.

[0032] Furthermore, by weight, the water storage layer comprises 0.1–10 parts sponge, 10–50 parts diatomaceous earth, 10–20 parts vermiculite, 10–20 parts perlite, 5–15 parts sawdust, 20–30 parts polyacrylate superabsorbent resin, 5–10 parts cellulose, 6–10 parts carrageenan, and 5–20 parts potassium alginate; the mass ratio of garden soil to peat soil is 3:2, and the concentration of the mixed gibberellin solution is 50–100 mg / L. The proportions of the raw materials in the water storage layer determine the overall water storage and retention capacity of the water storage layer. The process involved breaking sponges into 3-7cm pieces of any shape, mixing them evenly with other raw materials, and then fixing them together with other layers to form an ecological blanket. After this, a water-absorbing treatment was performed: the water-retaining layer was mixed evenly, compacted, and then completely submerged in water for 30-1 hour, followed by draining until no more water dripped. Plant fiber blankets were treated in the same way, with a control group (no plant fiber blankets used). Water retention performance was tested under local natural conditions (no rain and temperature between 15-28℃). The results are shown in Table 1. Table 1 shows that groups 1-3 had higher humidity and better water retention; however, materials such as sawdust showed signs of mold growth, which tended to persist over time. Control groups 1 and 2, lacking plant fiber blankets, experienced faster moisture loss. Therefore, groups 4 and 5 had more suitable humidity levels.

[0034]

[0035]

[0036] In practical use, the prepared ecological blanket is soaked in water (30-1 hour), with the water depth not exceeding the water storage layer. After the water storage layer has absorbed water, water is sprayed onto the surface of the ecological blanket until water droplets appear on the surface of the Selaginella. After the ecological blanket has been maintained for 1-2 months, trenches are dug on the slope requiring revegetation, the ecological blanket is placed in the trenches, and fixed in the trenches with anchoring stakes. The edges of the trenches can be covered with soil or stones depending on the condition of the edges, allowing for natural growth. The slope revegetation method disclosed in this invention eliminates the need to wait for plants to germinate and grow on the slope, reducing plant death and germination failure. After the ecological blanket is laid on the slope, the plant roots can take root on the slope more quickly than seeds germinate directly on the slope, achieving rapid slope revegetation and effectively preventing soil erosion. It should be noted that in order to ensure the early growth of plants, after the ecological blanket is maintained, water should be added to the water storage layer and the plant fiber blanket to keep the humidity of the water storage layer at 60-80% to meet the needs of plant growth, so that it can grow rapidly and take root on the slope.

[0037] refer to Figures 1-7As shown, the ecological carpet making device disclosed in this invention includes a making groove 1 with an open top. The making groove is rectangular. An adjusting plate 2 is vertically arranged on one side of the making groove 1 along its length direction. The adjusting plate can move along the width direction of the making groove, thereby adjusting the width of the ecological carpet. Specifically, an adjusting rod 3 is rotatably connected to one side of the adjusting plate 2. The adjusting rod and the adjusting plate are fixed together by a bearing. One end of the adjusting rod 3 extends out of the side wall of the making groove 1. The adjusting rod and the side wall of the making groove are connected by a thread. A turntable is fixed to the end of the adjusting rod extending out of the making groove. By rotating the turntable, the adjusting rod rotates, causing the adjusting plate to move towards the inside of the making groove, thereby controlling the distance between the adjusting plate and the side wall of the making groove.

[0038] Furthermore, to ensure the stability of the adjusting plate during adjustment, telescopic sleeves 27 are installed on the side wall of the manufacturing groove corresponding to the adjusting plate. These telescopic sleeves are positioned near both ends of the adjusting plate and are located on the same side as the adjusting rod. The telescopic sleeves penetrate the side wall of the manufacturing groove, with the larger diameter section fixed to the outer wall of the groove and the smaller diameter section fixed to the side wall of the adjusting plate. Springs can be installed inside the telescopic sleeves as needed.

[0039] Furthermore, positioning strips 4 are provided within the production trough 1 and the area enclosed by the production trough 1 and the adjusting plate 2. The number and arrangement of the positioning strips are determined according to actual needs. Taking a width of 30cm for the ecological blanket as an example, the distance between the adjusting plate and the side wall of the production trough is controlled at 30cm by adjusting the adjusting plate, allowing for a certain degree of error. As one embodiment, see reference... Figure 1 As shown, the positioning strip 4 is positioned close to the side wall of the manufacturing groove 1 and the adjusting plate 2, that is, the positioning strip is arranged in a circle along the side wall of the manufacturing groove and the adjusting plate. Several positioning posts 5 are arranged through the positioning strip 4, and a pressing strip 6 is fixed above the positioning strip 4 through the positioning posts 5. The positioning strip 4 and the pressing strip 6 press and fix the edge of the ecological blanket.

[0040] Furthermore, the positioning post 5 is a tubular shape with openings at both ends. A baffle 7 is provided circumferentially at one end of the positioning post 5; the baffle can be annular. Multiple frustum-shaped locking platforms 8 are equidistantly arranged along the axial direction of the positioning post 5, meaning the positioning post passes through the axis of the locking platform. The larger diameter end of the locking platform 8 faces the baffle 7. The positioning post 5 passes through the bottom of the positioning strip 4, causing the baffle 7 to contact the positioning strip 4, preventing separation between the positioning post and the positioning strip. In actual use, the positioning post is first passed through the bottom of the positioning strip. To prevent the positioning post from tipping over with the positioning strip, a limiting groove 28 is provided at the bottom of the manufacturing groove, allowing the baffle to engage within the limiting groove, thus fixing the positioning post and the positioning strip. The limiting groove is located in the width direction of the manufacturing groove and at the bottom of the side corresponding to the adjusting plate. Of course, under the action of the adjusting plate, the positioning strip near the adjusting plate can be squeezed. Under the action of the positioning strip set in the width direction, the positioning strip on this side will press against the positioning strip in the width direction and press against the positioning strip in the length direction on the other side, forming a tight "mouth" shaped structure.

[0041] Furthermore, after the positioning strip 4 and the clamping strip 6 are fixed, a fixing pile 9 is inserted from the top of the positioning column 5. A pressure plate 10 is installed at the top of the fixing pile 9, with one end being a pointed tip. The surface of the pressure plate is larger than the outer diameter of the top surface of the positioning column. Multiple frustum-shaped limiting platforms 11 are equidistantly arranged along the axial direction of the fixing pile 9, with the larger diameter end of each limiting platform 11 facing the pressure plate 10. It should be noted that the fixing pile can be directly inserted into the positioning column during use; it can be inserted into the soil layer of the slope by stepping on it. The locking platforms not only prevent the positioning column from separating from the positioning strip but also fix the clamping strip to the positioning column. Multiple locking platforms allow for flexible adjustment of the clamping strip's position on the positioning column according to the thickness of the ecological blanket. To avoid environmental pollution, the positioning column, positioning strip, clamping strip, and fixing pile are all made of wood, bamboo, biodegradable plastics, etc. These materials have a certain degree of deformation capability and can be degraded over time, thus not causing environmental pollution and requiring no manual removal. When the positioning post passes through the positioning strip and the clamping strip, force is required, which restricts the clamping platform on the clamping strip and the positioning strip. Similarly, the same applies to the fixing pile. The setting of the upper limit platform on the fixing pile not only enhances the fixation with the positioning post, but also increases the fixing pile's grip on the slope, that is, better fixes the ecological blanket on the slope.

[0042] Furthermore, parallel slide rails 12 are provided on the top of the fabrication tank 1 along its width, with both ends of the slide rails fixed by bases. Slider blocks 13 are mounted on the slide rails 12, moving along the slide rails. A guide rod 14 is provided between the two sliders 13, adjusting the position of the guide rod on the fabrication tank via the sliders and slide rails. Both ends of the guide rod are also fixed to the top of the sliders by bases. A sliding sleeve 15 is provided on the guide rod 14, with support plates 16 corresponding to both sides of the sliding sleeve 15. A loading trough 17 is provided on the sliding sleeve 15 and the support plates 16. An arched groove 18 adapted to the sliding sleeve 15 is provided at the bottom of the loading trough 17, and a discharge pipe 19 is provided on at least one side of the loading trough 17, facing the width direction of the fabrication tank 1. It should be noted that the loading trough moves along the guide rod, sequentially spreading the materials of the water storage layer and the matrix layer into the fabrication tank through the discharge pipe. When the width of the eco-mat being produced is small, a filling trough can be omitted, and manual operation can be performed directly. In this case, the guide rod can be moved aside via a slide rail. In practical applications, the guide rod and sliding sleeve can be square, as can the arched groove. However, when square, the friction between the sliding sleeve and the guide rod is relatively large; therefore, a cylindrical shape is preferred. The guide rod can be a screw rod, and the sliding sleeve can be a threaded sleeve. A motor is installed at one end of the guide rod, driving the filling trough to move along the guide rod, thereby achieving the laying of each layer of material.

[0043] Furthermore, to increase the stability of the loading trough on the sliding sleeve and support plate, telescopic members 22 are provided on both sides of the sliding sleeve 15, below the support plate 16. The other end of the telescopic member 22 extends to the top of the production trough 1 along its length and the top of the adjusting plate 2, respectively, and a roller 23 is provided at the bottom. When the loading trough moves along the guide rod, the roller slides on the top of the production trough and the adjusting plate, reducing the friction between the telescopic member and its top, while also ensuring the balance of the loading trough and supporting it. Of course, through holes can be provided on the support plate, and the loading trough can be fixed to the support plate by a pin, which can better increase the stability of both. However, compared with placing the loading trough directly on the support plate, the operability is poor.

[0044] Furthermore, to ensure the material is evenly distributed within the manufacturing trough via the loading trough, two feeding pipes are installed on each side of the loading trough, angled downwards and positioned on either side of the guide rod. A feeding trough 25 is installed at the outlet of each of the two feeding pipes on each side. The downward-facing side of the feeding trough 25 is open, and the outlet end of the feeding pipe is inserted into and fixed to the side wall of the feeding trough corresponding to the open side, such as using L-shaped connecting pieces and screws. The feeding trough is located below the guide rod. Figure 5 As shown. A baffle plate 26 is installed at the connection between the feeding pipe and the loading trough, and the opening and closing of the feeding pipe is controlled by the baffle plate.

[0045] Furthermore, to reduce material accumulation in the loading trough, a guide plate 20 inclined towards the connection between the discharge pipe 19 and the loading trough 17 is provided inside the loading trough 17. When the discharge pipe 19 is located on one side of the loading trough 17, the guide plate can be a straight plate inclined. When the discharge pipe 19 is located on both sides of the loading trough 17, the guide plate 20 is in the shape of a "∧", causing the material to move towards the inlet of the discharge pipe on both sides, making it easier for the material to enter the discharge pipe; the guide plate 20 is provided with a notch 21 for accommodating the arched groove 18.

[0046] Furthermore, when the required length of the ecological blanket is specified, two spacer strips 24 perpendicular to the positioning strips 4 are arranged side-by-side between adjacent positioning strips 4 along the length direction of the manufacturing groove 1. Once the ecological blanket is manufactured, it can be cut between the two spacer strips. Positioning posts 5 are also provided on the spacer strips 24; two positioning posts 5 are respectively provided on the positioning strips 4 near the ends of the spacer strips 24, as shown in the following configuration. Figure 1 As shown.

[0047] When using the ecological blanket making device of the present invention, prepare a certain number of spacer strips according to the size and needs, and adjust the size using an adjusting plate. Drill holes in the spacer strips and positioning strips according to the number of spacer strips, and insert positioning posts. Place the spacer strips and positioning strips in the making groove, and tighten them using the adjusting plate to fix them to the bottom of the making groove. Then lay the wire mesh, with the positioning posts passing through it, allowing the mesh to hang on it. A portion of the wire mesh's length can be reserved around the edges to wrap the ecological blanket. Next, lay the plant fiber blanket, with the positioning posts also passing through it. The plant fiber blanket can be cut to a specified size and placed within a single area enclosed by the spacer strips and positioning strips; alternatively, it can be laid directly within the area enclosed by the positioning strips. Then, pour the water storage layer material into the filling trough, move the filling trough, open the insert plate, and allow the material to fall into the making groove through the discharge pipe. Manually smooth the material. Then, pour in the substrate layer material and repeat the above operations.

[0048] Remove the filling trough, move the guide rail to the side, and lay the resurrection plant. Cover the surface of the resurrection plant with any excess mesh along the edges. Throughout the laying process, the positioning posts must pass through each layer of material. After the mesh is covered, fix the clamping strips to the positioning posts to tighten and secure the edges of the ecological blanket. Simultaneously, fix the clamping strips at the locations with spacers to divide the ecological blanket into squares of the required size. Loosen the adjusting plate, remove the ecological blanket, and cut it from the gap between two parallel spacers to obtain the specified size. During the cutting process, because the spacers are tightened and secured, and because the material above the spacers can be manually cut away when laying each layer, less material leaks after cutting. Alternatively, after the ecological blanket has been cured, it can be cut on the slope; any leaked material will remain on the slope, preventing waste. This also facilitates centralized curing and transportation, reducing labor intensity.

[0049] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0050] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
