Description

Technical Field

[0001] The invention relates to the technical field of slope restoration, and in particular to an ecological blanket for slope restoration and a restoration method. Background Art

[0002] With the increasing awareness of ecological protection, slope greening 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, slope greening ecological blankets have emerged as a new, environmentally friendly and economical slope protection material.

[0003] There are many types of slope greening ecological blankets, such as vegetation blankets, slope protection ecological blankets, plant fiber blankets, etc. These ecological blankets are usually made of natural plant fibers (such as coconut fiber, straw, etc.), geotextiles, grass seeds (optional) and nutrients. The structure is generally a multi-layer design, including an upper net, a fiber layer, a seed vegetation layer (such as with grass seeds) and a lower net.

[0004] However, the slope protection effect of the ecological blanket depends on the growth and reproduction of plant roots. However, the growth cycle of plants is long, and it takes a certain amount of time to form a dense vegetation layer. Therefore, it cannot be effective in a short period of time. Moreover, the ecological blanket is laid directly on the slope. During the laying process, it is impossible to ensure that the ecological blanket is closely integrated with the slope surface. Therefore, the growth of plant roots is restricted and the slope protection effect cannot be achieved. Moreover, during the period when the vegetation forms the vegetation layer, in the case of rainfall, the soil layer under the ecological blanket is prone to loss, which in turn aggravates the separation between the ecological blanket and the slope surface, making it impossible for plants to take root on the slope surface. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

[0030] The present invention discloses an ecological blanket for slope greening, wherein the ecological blanket comprises a reinforcement layer, an aquifer, a matrix layer and a surface layer from bottom to top, and the ecological blanket is wrapped and fixed by a wire net, and the thickness of the aquifer and the matrix layer are both 1 to 3 cm. The ecological blanket is made by an ecological blanket making device and cut to the required size. In order to prevent the aquifer and the matrix layer inside the ecological blanket from leaking after cutting, the periphery of the ecological blanket is sealed and fixed, that is, the making device disclosed by the present invention is used to fix the periphery of the ecological blanket, and at the same time, different sizes can be made as needed to meet different needs. The wire net 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 at the same time, strengthen and fix the aquifer to prevent the aquifer from leaking from the mesh of the wire net; the surface layer is Selaginella, specifically the mat-shaped Selaginella with good plants, which is laid on the matrix layer. The size of the ecological blanket is 30×30cm, and the number of mat-shaped Selaginella is set to 1 to 3 plants; the aquifer includes sponge, diatomaceous earth, vermiculite, perlite, sawdust, polyacrylic acid salt superabsorbent resin, cellulose, carrageenan and potassium alginate, and the matrix layer includes garden soil, peat soil, mixed gibberellin solution and organic fertilizer. Organic fertilizer can be fertilized by local fermented beer dregs, straw, etc.; native plant seeds are mixed into the matrix layer, and the amount of seeds, organic fertilizers and mixed gibberellin solution can be selected according to the prescribed amount. Finally, the aquifer and the matrix layer are mixed evenly and laid on the plant fiber blanket in turn, and the plant fiber blanket is placed on the wire net.

[0032] Furthermore, the aquifer includes 0.1-10 parts of sponge, 10-50 parts of diatomaceous earth, 10-20 parts of vermiculite, 10-20 parts of perlite, 5-15 parts of sawdust, 20-30 parts of polyacrylic acid salt superabsorbent resin, 5-10 parts of cellulose, 6-10 parts of carrageenan and 5-20 parts of potassium alginate in terms of weight; the mass ratio of the garden soil to the peat soil is 3:2, and the concentration of the mixed gibberellin solution is 50-100 mg / L. The ratio of the raw materials in the aquifer determines the water storage and water retention capacity of the entire aquifer. Among them, the sponge is broken into pieces of any shape with a size of 3 to 7 cm, mixed evenly with other raw materials, fixed with other layers to make an ecological blanket, and then treated with water absorption. The water storage layer is mixed evenly and compacted, and it is completely immersed in water for 30 to 1 hour, and then drained until no water drips; the plant fiber blanket is treated in the same way, and the control group is not used. The water retention performance is tested under the local natural environment (no rain, and the temperature is 15 to 28 ° C). The results are shown in Table 1 below. As can be seen from Table 1, Groups 1 to 3 have higher humidity and better water retention, but the sawdust and other materials therein are moldy, and there is a tendency to mold over time. Control Groups 1 and 2 lose water faster because there is no plant fiber blanket. Therefore, the humidity of Groups 4 and 5 is more appropriate.

[0033] Table 1 Water retention performance of aquifer (parts by weight)

[0034]

[0035]

[0036] In actual use, the prepared ecological blanket is soaked in water (30 to 1 hour), and the depth of the water does not exceed the aquifer. After the aquifer has finished absorbing water, water is sprayed on the surface of the ecological blanket until there are water droplets on the surface of the Selaginella. After the ecological blanket is maintained for 1 to 2 months, a groove is made on the slope that needs to be regreened, and the ecological blanket is placed in the groove. The ecological blanket is fixed in the groove by fixing piles. The edge of the groove can be covered with soil or stones according to the situation of the groove edge, and it is allowed to grow naturally. The slope regreening method disclosed in the present invention does not 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 root system of the plant can take root in the slope faster than directly germinating seeds on the slope, achieving rapid regreening of the slope and effectively preventing soil erosion on the slope. It should be noted that in order to ensure the early growth of plants, after the maintenance of the ecological blanket is completed, water is added to the aquifer and the plant fiber blanket to keep the humidity of the aquifer at 60-80% to meet the needs of plant growth, allowing them to grow rapidly and take root on the slope.

[0037] refer to Figure 1-Figure 7As shown, the ecological blanket production device disclosed in the present invention includes a production groove 1 with an opening at the top, and the production groove is selected to be rectangular. An adjustment plate 2 is vertically arranged on one side of the length direction of the production groove 1, and the adjustment plate can move along the width direction of the production groove, so as to adjust the width of the ecological blanket. Specifically: an adjustment rod 3 is rotatably connected to one side of the adjustment plate 2, and the adjustment rod and the adjustment plate can be fixed by a bearing. One end of the adjustment rod 3 extends out of the side wall of the production groove 1, and the adjustment rod and the side wall of the production groove can be connected by a thread. A turntable is fixed to the end of the adjustment rod extending out of the production groove. By rotating the turntable, the adjustment rod rotates, so that the adjustment plate moves toward the production groove, so as to control the distance between the adjustment plate and the side wall of the production groove.

[0038] Furthermore, in order to achieve stability of the adjustment plate during the adjustment process, a telescopic sleeve 27 is provided on the side wall of the production groove corresponding to the adjustment plate. The telescopic sleeves are respectively provided at positions close to both ends of the adjustment plate and are provided on the same side as the adjustment rod. The telescopic sleeve passes through the side wall of the production groove, and its large diameter section is fixed on the outer wall of the production groove, and the small diameter section is fixed on the side wall of the adjustment plate. A spring can be provided in the telescopic sleeve as required.

[0039] Furthermore, positioning strips 4 are arranged in the production groove 1 and in the area enclosed by the production groove 1 and the adjustment plate 2. The number and arrangement of the positioning strips are set according to actual needs. For example, the width of the ecological blanket is 30 cm. By adjusting the adjustment plate, the distance between the adjustment plate and the side wall of the production groove is controlled at 30 cm, and a certain error is allowed. As one embodiment, refer to Figure 1 As shown, the positioning strip 4 is arranged close to the side wall of the production groove 1 and the adjustment plate 2, that is, the positioning strip is arranged along the side wall of the production groove and the adjustment plate. A plurality of 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 column 5 is in the shape of a tube with openings at both ends, and a baffle 7 is provided on one end of the positioning column 5 in the circumferential direction, and the baffle may be annular, and a plurality of truncated cone-shaped clamping platforms 8 are provided equidistantly along the axial direction of the positioning column 5 in the circumferential direction, that is, the positioning column is provided through the axis of the clamping platform, and the large diameter end of the clamping platform 8 is provided toward the baffle 7, and the positioning column 5 passes through the bottom of the positioning bar 4, so that the baffle 7 contacts the positioning bar 4, and the positioning column and the positioning bar are prevented from being separated. In actual use, the positioning column is first passed through the positioning bar from the bottom of the positioning bar, and in order to prevent the positioning column from tipping over with the positioning bar, a limiting groove 28 is provided at the bottom of the manufacturing groove, so that the baffle is clamped into the limiting groove to fix the positioning column and the positioning bar; the limiting groove is provided in the width direction of the manufacturing groove and at the bottom of the side corresponding to the adjustment plate. Of course, under the action of the adjustment plate, the positioning strip close to the adjustment plate can be squeezed, and under the action of the positioning strip set in the width direction, the positioning strip on this side will press the positioning strip in the width direction tightly, and press the positioning strip in the length direction on the other side tightly, forming a tight "mouth" shaped structure.

[0041] Further, after the positioning strip 4 and the pressing strip 6 are fixed, a fixing pile 9 is inserted from the top of the positioning column 5, and a pressing plate 10 is arranged on the top of the fixing pile 9, and the other end is a pointed end, and the plate surface of the pressing plate is larger than the outer diameter of the top surface of the positioning column. A plurality of truncated cone-shaped limiting platforms 11 are arranged equidistantly along the axial direction of the fixing pile 9, and the large diameter end of the limiting platform 11 is arranged toward the pressing plate 10. It should be noted that when the fixing pile is in use, it can be directly inserted into the positioning column, and can be inserted into the soil layer of the slope through the positioning column by stepping on it. The setting of the card platform not only avoids the separation of the positioning column and the positioning strip, but also enables the pressing strip to be fixed on the positioning column, and the setting of multiple card platforms can flexibly adjust the position of the pressing strip fixed on the positioning column according to the thickness of the ecological blanket. In order to avoid environmental pollution, the positioning column, the positioning strip, the pressing strip and the fixing pile are all made of wood materials, bamboo, degradable plastics, etc. These materials have a certain degree of deformation ability, and can be degraded over time, will not cause environmental pollution, and do not need to be manually removed. When the positioning column passes through the positioning strip and the compression strip, force is required, so that the clamping platform restricts the compression strip and the positioning strip. Similarly, the same is true for the fixed pile. The setting of the upper limit platform on the fixed pile can not only enhance the fixation with the positioning column, but also increase the grip of the fixed pile on the slope, that is, better fix the ecological blanket on the slope.

[0042] Furthermore, the top of the production tank 1 is provided with mutually parallel slide rails 12 along its width direction, and the two ends of the slide rails are fixed by a base. The slide rail 12 is provided with a slider 13, and the slider moves along the slide rail. A guide rod 14 is provided between the two sliders 13, and the position of the guide rod on the production tank is adjusted by the slider and the slide rail. The two ends of the guide rod are also fixed to the top of the slider through the base. A sliding sleeve 15 is provided on the guide rod 14, and support plates 16 are provided on both sides of the sliding sleeve 15, respectively. A loading trough 17 is provided on the sliding sleeve 15 and the support plate 16, and an arch groove 18 adapted to the sliding sleeve 15 is provided at the bottom of the loading trough 17, and a feeding pipe 19 is provided on at least one side of the loading trough 17, and the feeding pipe 19 is arranged in the width direction of the production tank 1. It should be noted that the loading trough moves along the guide rod, and the materials of the water storage layer and the matrix layer are spread in the production tank in sequence through the feeding pipe. When the width of the ecological blanket is small, the loading trough can be omitted and manual operation can be performed directly. In this case, the guide rod can be moved to the side through the slide rail. In actual application, the guide rod and the sliding sleeve can be square, and the arch groove can also be square. However, when it is square, the friction between the sliding sleeve and the guide rod is large, so it can be preferably cylindrical. The guide rod can be a screw rod, and the sliding sleeve can be a screw sleeve. A motor is set at one end of the guide rod, and the motor drives the loading trough to move along the guide rod, thereby realizing the laying of each layer of material.

[0043] Furthermore, in order to increase the stability of the loading trough on the sliding sleeve and the support plate, telescopic parts 22 are provided on both sides of the sliding sleeve 15 and below the support plate 16. The other ends of the telescopic parts 22 extend to the top of the length direction of the production trough 1 and the top of the adjustment plate 2, respectively, and rollers 23 are provided at the bottom. When the loading trough moves along the guide rod, the rollers slide on the top of the production trough and the adjustment plate to reduce the friction between the telescopic parts and the top of the telescopic parts. At the same time, the balance of the loading trough is ensured and the loading trough is supported. Of course, through holes can be provided on the support plate, and the loading trough and the support plate are fixed by pins, which can better increase the stability of the two. However, compared with directly placing the loading trough on the support plate, the operability is poor.

[0044] Furthermore, in order to make the material pass through the loading trough and be laid in the production trough more evenly, the feed pipes are arranged on both sides of the loading trough, and two are arranged on each side, which are arranged tilted downward and located on both sides of the guide rod. A feed trough 25 is arranged at the outlet of the two feed pipes on each side, and the feed trough 25 is open on one side facing downward. The outlet end of the feed pipe is inserted into the side wall corresponding to the open side of the feed trough and fixed, such as by an L-shaped connecting piece and screws. The feed trough is located below the guide rod, such as Figure 5 A plug plate 26 is provided at the connection between the feeding pipe and the charging trough, and the opening and closing of the feeding pipe is controlled by the plug plate.

[0045] Furthermore, in order to reduce the accumulation of materials in the charging trough, a guide plate 20 is provided in the charging trough 17, which is inclined toward the connection port between the feeding tube 19 and the charging trough 17. When the feeding tube 19 is provided on one side of the charging trough 17, the guide plate can be a straight plate inclined. When the feeding tube 19 is provided on both sides of the charging trough 17, the guide plate 20 is in a "∧" shape, so that the materials move toward the inlets of the feeding tubes on both sides, and the materials are more easily entered into the feeding tubes; the guide plate 20 is provided with a notch 21 for accommodating the arch groove 18.

[0046] Furthermore, when the length of the ecological blanket is required, two spacer bars 24 perpendicular to the positioning bars 4 are arranged side by side between adjacent positioning bars 4 in the length direction of the production groove 1. When the ecological blanket is completed, it can be cut from between the two spacer bars. The spacer bar 24 is also provided with positioning posts 5; two positioning posts 5 are respectively arranged on the positioning bar 4 and at the ends close to the spacer bar 24. The arrangement is as follows: Figure 1 shown.

[0047] When using the ecological blanket making device of the present invention, a certain number of spacers are prepared according to the size and needs, and the size is adjusted by the adjustment plate; holes are drilled on the spacers and positioning bars according to the number of spacers, and positioning columns are inserted, and then the spacers and positioning bars are placed in the making groove, and the positioning bars and spacers are fixed to the bottom of the making groove by the adjustment plate. Then the wire net is laid, and the positioning columns pass through the wire net so that the wire net is hung on it. A part of the length around the wire net can be reserved to wrap the edge of the ecological blanket. Then the plant fiber blanket is laid, and the positioning columns also pass through the plant fiber blanket; the plant fiber blanket can be cut into a specified size and placed in a single area surrounded by the spacers and positioning bars; it can also be directly laid in the area surrounded by the positioning bars. Then, the aquifer material is poured into the loading trough, the loading trough is moved, the plug board is opened, and the material falls into the making trough through the feeding pipe, and the material is manually arranged and leveled; then, the matrix layer material is poured, and the above operation is repeated.

[0048] Remove the loading chute, move the guide rail to the side, lay the Selaginella, and cover the surface of the Selaginella with the excess wire mesh on the edge. During the entire laying process, the positioning column needs to pass through each layer of material. After the wire mesh is covered, fix the compression strip on the positioning column, and press and fix the edge of the ecological blanket. At the same time, the compression strip is also fixed at the position where the spacer is set, and the ecological blanket is divided into squares of required size. Loosen the adjustment plate, take out the ecological blanket, and cut the ecological blanket from the gap between the two parallel isolation strips to obtain an ecological blanket of specified size. During the cutting process, since the position of the spacer is pressed and fixed, at the same time, when laying each layer of material, the material above the spacer can be manually planed open. After cutting, less material leaks. Another way is that after the ecological blanket is maintained, it is cut on the slope, and the leaked material is on the slope without waste. At the same time, it is also convenient for centralized maintenance and transportation, reducing labor intensity.

[0050] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
