Specific embodiments

[0018] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] Example 1, as shown in Figure 1-2 shown, an ecological protection device for slope drainage and revegetation includes a drainage ditch 1. A grid plate 2 is provided on the upper side of the inner cavity of the drainage ditch 1. A limit frame 3 is provided at the rear end of the drainage ditch 1. A permeable geotextile 5 is provided in the inner cavity of the limit frame 3. A permeable pipe 4 is provided in the inner cavity of the permeable geotextile 5. The rear side of the upper end of the limit frame 3 is fixedly connected to a frame mechanism 6. Two water retention and soil fixation mechanisms 7 are provided in the middle and lower parts of the frame mechanism 6. Diamond-shaped grids two 8 and vegetation nets two 9 are provided on the left and right sides of the upper side of the frame mechanism 6, and the diamond-shaped grid two 8 on the same side is located on the upper side of the surface of the vegetation net two 9.

[0020] First, the construction workers first trim the slope to ensure its stability, remove the floating stones, loose soil blocks, vegetation roots and other sundries that may affect the slope stability on the slope, and level and compact the slope, so that the slope can reach the slope ratio and flatness required by the design, creating good conditions for the subsequent protection construction. Then, through construction, the frame mechanism 6 is placed at a suitable position on the slope. Then, the vegetation net two 9 is laid in the frame mechanism 6 from top to bottom, and then the diamond-shaped grid two 8 is laid. And the water-retaining and soil-fixing mechanism 7 is laid in the middle and lower parts of the frame mechanism 6. After the laying is completed, a groove adapted to the limit frame 3 is excavated on the lower side of the slope. Then, the permeable geotextile 5 is laid in the groove, so that the permeable geotextile 5 fits with the groove. Then, the drain pipe 4 is placed into the permeable geotextile 5. Then, gravel is added to the permeable geotextile 5 for backfilling to a suitable height, and the permeable geotextile 5 on the upper side of the gravel is covered to wrap the backfilled gravel. Then, a layer of gravel parallel to the ground is laid on the upper side of the permeable geotextile 5. A groove adapted to the drainage ditch 1 is excavated again in front of the drain pipe 4 for placing the drainage ditch 1. After the drainage ditch 1 is laid, the grid plate 2 is covered on the drainage ditch 1. Finally, a mixture of plant seeds and auxiliary materials is sprayed in the water-retaining and soil-fixing mechanism 7, the diamond-shaped grid two 8 and the vegetation net two 9. The auxiliary materials include substances such as soil improvers, fertilizers, water retainers, adhesives and fiber coverings, so that the plant seeds can germinate and grow normally, completing the revegetation operation. When it rains, the rainwater falls on the frame mechanism 6, the water-retaining and soil-fixing mechanism 7, the diamond-shaped grid two 8 and the vegetation net two 9, and the vegetation net two 9 is composed of a multi-layer plastic concave-convex net and a high-strength flat net, forming a net-like three-dimensional structure. The three-dimensional structure enables the plant roots to penetrate through it and firmly combine with the soil, thereby enhancing the attachment ability of the plants to the slope. Through the growth of the vegetation and the soil-fixing effect of the roots, the vegetation net two 9 can effectively prevent soil erosion on the slope. Some soil will also be intercepted in the diamond-shaped grid two 8. The rainwater then flows onto the first layer of gravel and sequentially penetrates through the permeable geotextile 5 and the backfilled gravel and drains away along the drain pipe 4, discharging the groundwater or surface water accumulation inside the slope, avoiding the accumulation of water inside the slope, reducing the water content of the slope, and reducing the softening, scouring and erosion effects of water on the slope soil, thereby improving the stability of the slope. In addition, the excess rainwater can also be drained away through the drainage ditch 1.

[0021] No electrical equipment is installed in the whole device, which reduces the manufacturing cost while achieving the expected effect, making the device suitable for large-scale promotion, especially in slope drainage and revegetation projects such as mines and barren mountains. In addition, in the hydroseeding revegetation project, hydroseeding vegetation seeds and auxiliary materials are used to form a substrate layer suitable for plant growth. The auxiliary materials include auxiliary materials, fertilizers, water retainers, adhesives, and fiber coverings. Among them, the soil conditioner is used to improve the soil structure, enhance soil fertility and water retention capacity, and provide a good soil environment for plant growth. Fertilizers can provide the nutrients required for plant growth, promoting the rapid growth and development of plants. Water retainers can absorb and store a large amount of water and slowly release it during dry periods to ensure the water supply required for plant growth. Adhesives can help adhere the hydroseeding materials to the slope surface, prevent soil erosion, and ensure the stability of the hydroseeding layer. Fiber coverings such as wood fibers and pulp can increase the thickness and stability of the hydroseeding layer and provide the organic matter required for plant growth at the same time.

[0022] To achieve slope drainage and revegetation, as Figure 3 , Figure 4 and Figure 5 shown, the frame mechanism 6 includes a frame body 61. A drainage groove 62 is jointly opened at the upper end of the frame body 61 and the inclined surface. Four arched placement grooves 63 are opened on the inclined surface of the frame body 61. Symmetrically arranged placement grooves one 65 are opened on the upper side of the inclined surface of the frame body 61. Four water permeable grooves 64 are opened in the middle and upper parts on the side of the frame body 61 away from the drainage groove 62. Four mounting holes 66 are opened on the lower side of the inner cavity bottom wall of the drainage groove 62. Drainage groups 67 are provided in the inner cavities of the four mounting holes 66. The lower side of the outer surface of the frame body 61 is fixedly connected to the rear side of the upper end of the limit frame 3. The rear sides of the inner cavities of the two placement grooves one 65 are respectively attached to the two vegetation nets two 9. The front sides of the inner cavities of the two placement grooves one 65 are respectively attached to the two diamond-shaped grilles two 8.

[0023] First of all, a drainage groove 62 is opened on the surface of the frame body 61. In rainy days, rainwater can flow along the drainage groove 62 into the permeable pipe 4 or the drainage ditch 1. By opening the arched placement grooves 63 and the placement grooves one 65, it is used to place the water retention and soil fixation mechanism 7, as well as the diamond-shaped grille two 8 and the vegetation net two 9. The revegetation operation is completed by hydroseeding a mixture of plant seeds and auxiliary materials on the water retention and soil fixation mechanism 7, the diamond-shaped grille two 8, and the vegetation net two 9. Moreover, the mounting holes 66 opened at the bottom of the drainage groove 62 are used to install the drainage groups 67, so that the drainage groups 67 penetrate the mounting holes 66 and are inserted into the soil of the slope. In rainy days, the water inside the slope can be discharged into the drainage groove 62 through the drainage groups 67 and flow out along the drainage groove 62, and the soil will not be lost, ultimately achieving the purpose of slope drainage and revegetation.

[0024] Furthermore, as Figure 6As shown in the figure, the four drainage groups 67 each include a drain pipe 671. Threaded grooves 672 are provided on the front sides of the inner cavities of the four drain pipes 671. Threaded caps 674 are engaged and connected to the inner cavities of the four threaded grooves 672. Clamping plates 673 are fixedly connected to the upper sides of the front ends of the four threaded caps 674. Drainage holes 675 are provided in the lower parts of the front ends of the four threaded caps 674. Drainage inner pipes 676 are fixedly connected to the front walls of the inner cavities of the four threaded caps 674. Conical scraping pieces 677 are fixedly connected to the rear sides of the outer surfaces of the four drainage inner pipes 676. The outer surfaces of the four conical scraping pieces 677 are respectively slidably connected to the inner cavities of the four drain pipes 671. The outer surfaces of the four drain pipes 671 are respectively slidably connected to the inner cavities of the four mounting holes 66.

[0025] Specifically, in rainy days, the water inside the slope can pass through the drain pipe 671 and the drainage inner pipe 676, and the excess water accumulates in the inner cavities of the drain pipe 671 and the drainage inner pipe 676. The accumulated water can be discharged into the drainage groove 62 through the drainage holes 675 and then discharged through the drainage groove 62. A small amount of soil may penetrate into the drain pipe 671 and be blocked by the drainage inner pipe 676. When a certain amount is reached, the threaded cap 674 is driven to rotate in the inner cavity of the threaded groove 672 by the clamping plate 673, so that the threaded cap 674 pulls the drainage inner pipe 676 out of the inner cavity of the drain pipe 671. At the same time, the conical scraping piece 677 will be driven to scrape out the soil that has penetrated into the drain pipe 671, so that the drainage group 67 can discharge the excess rainwater while retaining the soil.

[0026] Embodiment 2. On the basis of Embodiment 1, the operation of slope revegetation is completed, as Figure 7 、 Figure 8 and Figure 9 shown in the figure. The water and soil conservation mechanism 7 on the same side includes a diamond-shaped grille 71. A vegetation net 72 is provided on the rear side of the outer surface of the diamond-shaped grille 71. A water storage group 74 is provided behind the vegetation net 72. A number of drainage holes 73 are provided in the inner cavity of the vegetation net 72. The rear sides of the inner cavities of the four arched placement grooves 63 are respectively in contact with the four vegetation nets 72. The front sides of the inner cavities of the four arched placement grooves 63 are respectively in contact with the four diamond-shaped grilles 71.

[0027] After the vegetation net II 9 and the diamond grille II 8 are sequentially laid in the inner cavity of the placement groove I 65, then the water storage group 74 is laid in a suitable position in the arched placement groove 63, so that the inner cavities of the two water permeable grooves 64 in the inner cavity of the arched placement groove 63 on the same side are respectively aligned with the left and right sides of the water storage group 74, enabling the excess rainwater within the range of the placement groove I 65 during rainy days to pass through the water permeable grooves 64 and enter the water storage group 74 in the middle. And when the excess rainwater within the range of the middle arched placement groove 63 can also enter the water storage group 74 at the lower side through the water permeable groove 64 in the middle. After the laying of the water storage group 74 is completed, the vegetation net I 72 and the diamond grille I 71 are sequentially laid. Moreover, the vegetation net I 72 is the same as the vegetation net II 9, and the diamond grille I 71 is the same as the diamond grille II 8. And drainage holes II 73 are provided in each diamond space of the diamond grille I 71, enabling the excess rainwater in each diamond space to flow out along the drainage holes II 73, achieving the purpose of discharging excess rainwater. And after a certain amount of rainwater is stored by the water storage group 74, the excess rainwater can be discharged, and the stored rainwater can provide moisture for the vegetation on the vegetation net I 72 during dry weather, playing the role of discharging the excess rainwater on the slope, and at the same time achieving the purpose of retaining part of the rainwater to provide water sources for the vegetation during the dry period.

[0028] In addition, the vegetation net II 9 and the vegetation net I 72 are used to plant vegetation through the spray seeding and revegetation project. The spray seeding and revegetation project usually adopts a mechanized operation method, using special spray seeding equipment to evenly spray seeds and auxiliary materials. This method has high efficiency, low cost, and can ensure the uniformity and coverage rate of spray seeding. And the spray seeding and revegetation project is applicable to various terrain and soil conditions, including steep slopes, bare rock surfaces, and areas with poor soil fertility, etc. Through the spray seeding and revegetation project, large-area vegetation coverage can be achieved in a short time, effectively preventing soil erosion and ecological degradation. At the same time, as the plants grow and develop, it can gradually improve the soil structure, increase soil fertility, and promote the restoration and reconstruction of the ecosystem. When used in conjunction with this device, it can more conveniently complete the revegetation and drainage protection operations of the slope, further improving the promotion of the device.

[0029] Further explanation, such as Figure 10 and Figure 11As shown, the water storage group 74 on the same side includes a water collecting box 742, and a left-right symmetrical drainage groove 743 is opened on the front side of the outer surface of the water collecting box 742, a cover plate 744 is slidably connected to the upper side of the inner cavity of the water collecting box 742, and a sleeve 754 is connected to the inner cavity of the water collecting box 742, and a left-right symmetrical through hole 746 is opened on the rear side of the outer surface of the water collecting box 742. One end of the columnar cotton 745 away from the through hole 746 penetrates the cover plate 744 and is fixedly connected to a grid cotton cloth 741, and the front sides of the outer surfaces of the four grid cotton cloths 741 are respectively fitted with four vegetation nets 72, and the outer surfaces of the four grid cotton cloths 741 are respectively sleeved on the rear sides of the inner cavities of the four arched placement grooves 63, and the inner cavities of the eight drainage grooves 743 are respectively communicated with the lower sides of the inner cavities of the eight permeable grooves 64.

[0030] In detail, the columnar cotton 745 and the grid cotton cloth 741 are both made of non-woven fabrics, which can have good moisture retention ability in the underground environment, and can gradually release moisture to plants to promote the growth of seeds or plant roots. When laying the water collection box 742, it is necessary to align the lower sides of the inner cavities of the two permeable grooves 64 on the same side with the inner cavities of the drainage grooves 743 on the left and right sides, so that excess rainwater can pass through the inner cavities of the permeable grooves 64 and the drainage grooves 743 into the inner cavity of the water collection box 742, and absorb rainwater through the columnar cotton 745. When the amount of rainwater reaches the through hole 746, the excess water will be discharged from the inner cavity of the water collection box 742 through the through hole 746, and the grid cotton cloth 741 can also absorb rainwater on rainy days. In dry periods, rainwater in the inner cavity of the water collection box 742 can provide water for the vegetation on the vegetation net 72 through the columnar cotton 745 and the grid cotton cloth 741.
