[0002] Under natural conditions in cold and arid areas, the plant production cycle is short and the growth is slow. After the excavation of the artificial slope is completed, it is difficult to achieve the protection goal in the short term by using the conventional method of spraying grass seeds (including TBS) for greening. After being washed away by heavy rain during the growth period of the plants, it is very easy to cause the loss of surface water, soil and grass seeds, further reducing the protection effect of spraying grass. However, the use of artificial turf for transplantation has an immediate effect.

[0003] At present, the ordinary artificial turf on the market has harsh maintenance conditions and poor adaptability. The artificially planted grass that simulates the growth under local climatic conditions needs many years of growth to form a turf shape with a certain integrity. Therefore, it is more difficult to manufacture protective greening turf. Summary of the invention

[0004] In order to improve the above-mentioned problem that the common artificial turf currently on the market has harsh maintenance conditions and poor adaptability, and the artificially planted grass that simulates the growth under local climatic conditions needs many years of growth to form a turf shape with a certain integrity, and therefore it is difficult to manufacture the protective greening turf, the present invention provides an artificial slope greening turf protective layer in cold and arid areas and an implementation method thereof.

[0005] The present invention provides an artificial slope greening turf protective layer in cold and arid areas and an implementation method thereof, which adopts the following technical scheme:

[0006] An artificial slope greening turf protective layer in cold and arid areas comprises an artificial slope and a grid beam. The grid beam is fixed on the artificial slope by arranging node anchor rods, and an artificial turf protective layer is arranged in the grid beam.

[0007] Optionally, in the above-mentioned artificial turf protective layer for greening slopes in cold and arid areas, the artificial turf protective layer includes a nutrient base layer and a planting blanket, the nutrient base layer is arranged on the inner bottom wall of the grid beam, and the planting blanket is arranged on the top of the nutrient base layer.

[0008] Optionally, in the above-mentioned artificial slope greening turf protection layer in cold and arid areas, the planting blanket includes a fine-mesh geogrid, which is arranged on the top of the nutrient base layer, and two layers of three-dimensional geonets are arranged on the fine-mesh geogrid, and nutrient soil is laid between the two three-dimensional geonets.

[0009] Optionally, in the above-mentioned artificial slope greening turf protective layer in cold and arid areas, the fine-mesh geogrid and the side edges of the top three-dimensional geonet are sealed and tied with nylon ropes.

[0010] Optionally, in the above-mentioned artificial turf protective layer for greening slopes in cold and arid regions, the artificial turf protective layer is cut according to the internal size of the grid beam, and after cutting, the artificial turf protective layer is edge-sealed and tied around with nylon ropes.

[0011] Optionally, in the above-mentioned artificial slope greening turf protective layer in cold and arid areas, the nutrient base layer is sprayed inside the grid beam using the TBS process.

[0012] Optionally, in the above-mentioned artificial slope greening turf protective layer for cold and arid regions, the planting blanket is connected to the grid beam by arranging U-shaped nails.

[0013] Another technical solution proposed by the present invention is a method for implementing an artificial slope greening turf protective layer in cold and arid areas, comprising the following steps:

[0014] S101: Turf planting;

[0015] A. Build a turf maintenance shed and turf maintenance rack. The bottom of the maintenance rack should be permeable to water. Then cover the maintenance rack with a layer of river sand with a thickness of 10 cm.

[0016] B. Fine-mesh geogrids and three-dimensional geonets are laid on the upper part of the river sand layer, and nutrient soil is laid to cover the three-dimensional geonets. During the laying process, ensure that the three-dimensional geonets are filled completely without cavities;

[0017] C. Lay the top three-dimensional geonet, and then use nylon rope to tie the bottom fine-mesh geogrid and the top three-dimensional geonet at a spacing of 50 cm to form a planting blanket, and the total thickness of the planting blanket is 5 cm;

[0018] D. Spread the top nutrient soil to half the thickness of the top three-dimensional geonet, then sow grass seeds, and then cover with a layer of 0.5-1cm river sand;

[0019] E. Maintain according to local climatic conditions and appropriately control temperature, humidity and light;

In addition, the turf planted on the project site is more adapted to the local climate conditions and has a high survival rate.

[0027] By artificially simulating local ecological conditions, artificial turf is planted in a centralized manner, and transplanted as a whole when climatic conditions are suitable. A three-dimensional geonet is used to form a planting blanket with certain integrity and impact resistance, which can be arbitrarily cut according to the laying shape. Grass seeds are sown on the planting blanket to form artificially planted turf. Due to the integrity of the planting blanket, the overall transplantation can be achieved in the early stage of turf survival. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-3 The present invention is described in further detail.

[0033] Please refer to the attached figure in the instruction manual Figure 1-3 An embodiment of the present invention is: an artificial slope greening turf protection layer in cold and arid areas, including an artificial slope and a grid beam 1. It should be noted that the grid beam 1 serves as a partition and fixing structure for the slope support structure and the turf protection, and is used to improve the stability and scour resistance of the artificial slope. The grid beam 1 has various forms and can be selected according to the shape and aesthetic requirements of the slope protection.

[0034] The grid beam 1 is fixed on the artificial slope by setting the node anchor rod 2. After the excavation of the artificial slope is completed, the node anchor rod 2 and the grid beam 1 are set according to the slope stability requirements. The grid beam 1 is arranged close to the slope or a groove is excavated according to 1 / 3-1 / 2 of the height of the grid beam 1. The grid beam 1 protrudes from the surface of the slope and the height is not less than 20cm.

[0035] An artificial turf protective layer 3 is arranged inside the grid beam 1. The artificial turf protective layer 3 is cut according to the internal size of the grid beam 1, and after cutting, the artificial turf protective layer 3 is edge-sealed and tied with nylon ropes around the edges.

[0036] The artificial turf protective layer 3 includes a nutrient base layer 4 and a planting blanket 5. The nutrient base layer 4 is arranged on the inner bottom wall of the grid beam 1. It should be noted that the nutrient base layer 4 is sprayed inside the grid beam 1 using the TBS process, and the planting blanket 5 is arranged on the top of the nutrient base layer 4. Before covering the planting blanket 5, the TBS process is used to spray the nutrient base layer 4 with a thickness of 10 cm on the space inside the grid beam 1.

[0037] The planting blanket 5 is connected to the grid beam 1 by setting U-shaped nails 11. The length of the U-shaped nails 11 is greater than or equal to 30 cm, and the spacing is about 50 cm-100 cm, which is selected according to the slope of the slope. When the slope is steeper than 1:1, a small spacing is used, and when the slope is gentler than 1:1, a sparse spacing can be used.

[0038] The planting blanket 5 includes a fine-mesh geogrid 8, which is arranged on the top of the nutrient base layer 4. Two layers of three-dimensional geonet 9 are arranged on the fine-mesh geogrid 8. The sides of the fine-mesh geogrid 8 and the top three-dimensional geonet 9 are sealed and tied with nylon ropes to form an integral mesh, and the spacing between the nylon rope tying positions is 50 cm.

[0039] Nutrient soil 10 is laid between the two three-dimensional geonets 9, and the sowing of grass seeds is facilitated by the nutrient soil 10.

[0040] It should be noted that the inside and upper part of the bottom three-dimensional geonet 9 are covered with nutrient soil 10 with a total thickness of 5 cm. After the top three-dimensional geonet 9 is covered on the nutrient soil 10, the nutrient soil 10 continues to be covered to half the thickness of the geonet 9. After sowing grass seeds suitable for local growth, it is covered with river sand 7 with a thickness of no more than 1 cm. According to local climatic conditions, temperature, water and light are properly controlled for maintenance. The planting blanket 5 uses fine-mesh geogrids 8 and double-layer three-dimensional geonets 9 to form a multi-layer structure with certain integrity and impact resistance, and can be arbitrarily cut according to the laying shape.

[0041] By artificially simulating local ecological conditions, artificial turf is planted in a centralized manner, and transplanted as a whole when climatic conditions are suitable. A three-dimensional geonet 9 is used to form a planting blanket 5 with certain integrity and impact resistance, which can be arbitrarily cut according to the laying shape. Grass seeds are sown on the planting blanket 5 to form artificially planted turf. Due to the integrity of the planting blanket 5, the overall transplantation can be achieved in the early stage of turf survival.

[0042] In summary: first, cover the inside and upper part of the bottom three-dimensional geonet 9 with nutrient soil 10, cover the top three-dimensional geonet 9 on the nutrient soil 10, and then continue to cover the nutrient soil 10 to half the thickness of the geonet 9, sow grass seeds suitable for local growth, and then cover it with river sand 7. The thickness of the river sand 7 shall not exceed 1 cm, and according to local climatic conditions, appropriately control temperature, water, light, etc. for maintenance, and then use nylon rope to seal the edges and tie them to form a planting blanket 5. Then, before covering the planting blanket 5, the TBS process is used to spray a nutrient base layer 4 with a thickness of 10 cm on the space inside the grid beam 1 to form an artificial turf protective layer 3, and the artificial turf protective layer 3 is cut into a size corresponding to the inside of the grid beam 1, and then the artificial turf protective layer 3 is installed in the grid beam 1.

[0043] In order to better demonstrate an artificial slope greening turf protective layer in cold and arid areas, this embodiment now proposes an implementation method thereof, including the following steps:

[0044] Step 1: Planting turf;

[0045] A. Set up a turf maintenance shed and a turf maintenance frame 6, the bottom of the maintenance frame 6 is permeable, and then cover the maintenance frame 6 with a layer of river sand 7 with a thickness of 10 cm;
