Detailed Description of the Preferred Embodiments
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment 1:
[0024] Please refer to Figures 1 to 2 , a cutting slope protection structure in this embodiment includes two tops of the cutting 1, and a protection structure is arranged between the two tops of the cutting 1. The protection structure includes a concrete slab 2 fixedly connected to the opposite sides of the two tops of the cutting 1, a slope platform 10 fixedly connected between the two concrete slabs 2, a plurality of wire mesh anchor rods 7 vertically inserted into the inside of the slope platform 10, a plurality of plastic pipes 9 inserted into the slope platform 10 on the side close to the wire mesh anchor rods 7, a plurality of galvanized irons 14 attached to the front end surface of the slope platform 10, a galvanized wire mesh edge 15 tied and connected between adjacent galvanized irons 14, and a base material 6 laid on the side of the slope platform 10 close to the galvanized iron 14.
[0025] Among them, slope drainage holes 8 are provided inside the slope platform 10 on the side close to the plastic pipe 9. One side of the top of the cutting 1 away from the concrete slab 2 is fixedly connected with a concrete retaining wall 4. The side of the concrete retaining wall 4 away from the top of the cutting 1 is fixedly connected with a side ditch 5. The other side of the top of the cutting 1 away from the concrete slab 2 is fixedly connected with a concrete skeleton 3. The top of the cutting 1 and the concrete slab 2 are fixedly connected by concrete. The plastic pipe 9 is inserted into the slope drainage hole 8. The inner diameter of the slope drainage hole 8 is 50 mm. A plurality of wire mesh anchor rods 7 are arranged at equal intervals inside the slope platform 10. The outside of the wire mesh anchor rod 7 is wrapped with cement mortar. One side of the galvanized wire mesh edge 15 is fixed on the outer surface of the slope platform 10. The outside of the plastic pipe 9 is wrapped with an industrial polyester transition cloth.
[0026] It should be noted that the polyester transition cloth can separate liquid and solid during rainy days and can also be used for dust collection treatment of high-temperature gases, such as gas filtration in high-temperature environments of cement plants, iron-making plants, and iron-carbon plants. The mesh of the flower-shaped wire mesh is arranged in a 3×3 cm plum blossom pattern with a diameter of 5 mm. When selecting grass seeds, it is necessary to select perennial grass seeds with developed roots, short stems and lush leaves, and suitable for growth in this area, and the content of grass seeds sprayed per square meter is not less than 25 grams. During the spraying period, continuous feeding is required, and the air pressure of the spraying machine should be kept stable during operation. When the operation is completed or interrupted, the accumulated materials in the spraying machine and the feeding pipe should be removed. The grass seeds need to be watered and cured for no less than 20 days to ensure that the surface of the slope platform 10 always has sufficient moisture to promote the germination and growth of grass seeds.
[0027] Embodiment 2:
[0028] Please refer to Figures 2 to 4 , on the basis of Embodiment 1, a drainage and filtration device is provided on the left side of the slope platform 10. The drainage and filtration device includes a fixing plate 12 sleeved on the left side of the slope platform 10, a plurality of through holes 13 opened inside the fixing plate 12, a drainage groove 11 opened inside the left side of the slope platform 10, a plurality of filter mesh plates 17 fixedly connected to the slope platform 10 on the side close to the drainage groove 11, an electric push rod 16 fixedly installed inside the slope platform 10 near the upper end of the filter mesh plate 17, a baffle 18 fixedly connected to the output end of the electric push rod 16, and a left spring 19 fixedly connected to the upper side of the baffle 18.
[0029] By adopting the above technical solution, when the telescopic end of the electric push rod 16 extends, it can push the baffle 18 to move linearly on the filter mesh plate 17. During rainy days, rainwater enters the drainage groove 11 through the through holes 13 opened in the fixing plate 12. The filter mesh plate 17 filters out impurities to reduce the blockage in the drainage groove 11. At the same time, the output end of the electric push rod 16 pushes the baffle 18 to move regularly, pushing the filtered impurities to accumulate on one side surface of the fixing plate 12, reducing the blockage of the holes of the filter mesh plate 17 by the filtered impurities and improving the drainage fluidity.
[0030] The working principle of the above embodiment is:
[0031] Drill holes at the designed positions. The drilling direction should be perpendicular to the slope platform 10. Tighten the galvanized iron 14 and use wire to connect and fix the galvanized iron 14 to the edge 15 of the galvanized wire mesh. Then fix the column galvanized iron 14 with the wire mesh anchor 7. Open a drainage groove 11 on the surface of the slope platform 10, build a side ditch 5 and fix it at the bottom position. At the same time, insert a plastic pipe 9 into the slope drainage hole 8 for later drainage. Meanwhile, trim the slope platform 10, fill in the grooves and potholes, and prepare the spraying and planting mixture. The mixture should be sprayed immediately after mixing. Accurately measure the weight of the sown grass seeds and mix them fully with the base material 6 in the mixing device. Then control the spraying pressure to avoid damaging the surface of the rock bed and ensure uniform and stable spraying on the surface of the slope platform 10. Construction can be carried out in appropriate sections according to the project length, slope height and site conditions to achieve the purpose of slope reinforcement and greening.

The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed electrical connection technologies are not described in detail in the text.
