[0002] Slope spraying technology is a technology used for ecological restoration and slope greening. It is particularly suitable for slope protection in highway, railway, mine and other infrastructure construction. The main purpose of this technology is to accelerate the growth of vegetation by spraying a mixture containing plant seeds, fertilizers, fiber coverings, etc. (i.e., substrate), thereby achieving the effect of consolidating the soil, beautifying the environment, and reducing soil erosion. Common mine slope greening covering processes include: soil spraying, net spraying, spray-mixed vegetation, etc. These mine slope greening covering processes require the process of slope shaping-netting-anchoring-spraying. Moreover, the final effect of the mine slope greening covering process is strongly related to the stability of the netting, the ratio of the substrate, and the uniformity of the substrate spraying.

[0029] The utility model provides a hanging net assembly structure suitable for slope spraying, such as Figure 1As shown, the net assembly structure includes: a plurality of nets 100 laid on the slope, each of which is in a grid-like structure and connected to each other; a plurality of first assembly structures 200 in the shape of long blocks, each of which has a recessed portion, and the first assembly structures 200 are spaced apart on one side of each of the nets 100, for connecting the adjacent nets 100 of the first assembly structure 200 close to the net 100, and the first assembly structure 200 can also be vertically inserted into the slope. Provide a support point for one side of the hanging net 100; a number of second assembling structures 300 are in the shape of long blocks, each second assembling structure 300 has a protrusion, and the second assembling structures 300 are spaced apart on the other side of each of the hanging nets 100 relative to the first assembling structure 200, and are used to connect another adjacent hanging net 100 of the second assembling structure 300 close to the hanging net 100, and the second assembling structure 300 can also be vertically inserted into the slope to provide a support point for the other side of the hanging net 100.
[0030] The first assembling structure 200 and the second assembling structure 300 are arranged at the same interval.
[0031] The hanging net 100 is an n×n grid. In a specific construction environment, the hanging net 100 has three grid forms, namely, a 9 (3×3) grid type, a 16 (4×4) grid type, and a 36 (6×6) grid type.
[0032] In the specific use of the hanging net assembly structure, it is necessary to determine which mesh form of the hanging net 100 to use according to the amount of the substrate containing plant seeds, fertilizers, and fiber coverings to be sprayed.
[0033] The selection rules are as follows: If the substrate thickness during seeding is less than 8cm, use a 36-mesh hanging net 100; if the substrate thickness is between 10-15cm, use a 16-mesh hanging net 100; if the substrate thickness is greater than 15cm, use a 9-mesh hanging net 100. In other words, the thinner the substrate thickness during seeding, the denser the mesh size, to provide better protection for the newly seeded substrate.
[0034] Preferably, the hanging net 100 is made of galvanized iron mesh or PE (polyethylene) plastic.
[0035] Among them, Figure 2 As shown, the concave portion of the first assembling structure 200 matches the convex portion of the second assembling structure 300, and a mortise and tenon connection structure is formed after being plugged in.
[0036] Furthermore, the connection method between the hanging net 100 and the adjacent hanging net 100 near the first assembly structure 200 is: the recessed portion on the first assembly structure 200 of the hanging net 100 is connected to the protruding portion of the second assembly structure 300 on the adjacent hanging net 100 near the first assembly structure 200; the connection method between the hanging net 100 and another adjacent hanging net 100 near the second assembly structure 300 is: the protruding portion on the second assembly structure 300 of the hanging net 100 is connected to the recessed portion of the first assembly structure 200 on the other adjacent hanging net 100 near the second assembly structure 300.
[0037] Preferably, the first assembly structure 200 and the second assembly structure 300 are both made of PE (polyethylene) plastic.
[0038] In an embodiment of the present invention, the first assembling structure 200 is arranged on the two top corners on one side of the hanging net 100, that is, two first assembling structures 200 are arranged on one side of the hanging net 100; the second assembling structure 300 is arranged on the two top corners on the other side of the hanging net 100, that is, two second assembling structures 300 are arranged on the other side of the hanging net 100.
[0039] In another embodiment of the present invention, the first assembling structure 200 is arranged on the side grid points on one side of the hanging net 100; the second assembling structure 300 is arranged on the side grid points on the other side of the hanging net 100. Specifically, for a 9-grid hanging net 100, four first assembling structures 200 are arranged on the side grid points on one side of the hanging net 100, and four second assembling structures 300 are also arranged on the side grid points on the other side of the hanging net 100; for a 16-grid hanging net 100, five first assembling structures 200 are arranged on the side grid points on one side of the hanging net 100, and five second assembling structures 300 are also arranged on the side grid points on the other side of the hanging net 100; for a 36-grid hanging net 100, seven first assembling structures 200 are arranged on the side grid points on one side of the hanging net 100, and seven second assembling structures 300 are also arranged on the side grid points on the other side of the hanging net 100.
[0040] Further, if Figure 2As shown, the first assembly structure 200 and the second assembly structure 300 are in the shape of long blocks, that is, they have a certain length in the direction of vertical insertion into the slope. In this embodiment, the length of the hanging net 100 is 20 cm. In addition, scale lines are provided on the side walls of the first assembly structure 200 and the second assembly structure 300. The scale lines indicate the depth of insertion of the first assembly structure 200 and the second assembly structure 300 into the slope. By adjusting the depth of insertion of the first assembly structure 200 and the second assembly structure 300 into the slope, the distance of the hanging net 100 from the slope surface is adjusted, and finally a spraying thickness suitable for the actual conditions of the slope is achieved to ensure a good spraying effect. At the same time, the hanging net 100 maintains an appropriate distance from the slope surface, which also ensures the uniformity of the spraying to a certain extent and further improves the spraying effect.
[0041] In addition, the first assembly structure 200 and the second assembly structure 300 of the hanging net assembly structure can partially replace the function of anchor rods, thereby greatly reducing the amount of anchor rods used in slope seeding.
[0042] In a specific embodiment of the present invention, seeding was performed on a slope with a slope gradient of 70°, a slope height of 30m, and a surface rock composed of moderately weathered shale. In this embodiment, the seeding substrate was 18cm thick. Using the 9-grid mesh 100, only 20 main anchor rods and 20 secondary anchor rods were used. Using a conventional mesh would require 55 main anchor rods and 55 secondary anchor rods under these conditions.
[0043] Therefore, the hanging net assembly structure provided by the utility model can save 55% of the anchor rods; in addition, in the sampling test of 10 points in every 10 square meters, after adopting the hanging net assembly structure, the qualified rate of the spraying thickness reached 95%; three months after spraying, the vegetation coverage rate of the sprayed slope reached 75%, and six months after spraying, the vegetation coverage rate of the sprayed slope reached 85%.
[0044] To sum up, the utility model provides a hanging net assembly structure suitable for slope spraying, which improves the uniformity of slope spraying and the hanging net effect of the spraying substrate, and significantly improves the coverage rate of vegetation in the slope environment; at the same time, under the premise of ensuring the stability of the hanging net assembly structure, the use of anchor rods is reduced, that is, the construction cost is reduced.
[0045] Although the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description should not be construed as limiting the present invention. After reading the above description, various modifications and alternatives to the present invention will become readily apparent to those skilled in the art. Therefore, the scope of protection of the present invention shall be defined by the appended claims.
