Description

Technical Field

[0001] The utility model relates to the field of slope greening, in particular to a greening structure applicable to the space between frames on high-steep rocky slopes. Background Art

[0002] Rocky slopes have environmental characteristics such as high steepness, aridity, and infertility, which together make it difficult to establish and maintain a long-term effective greening structure on rocky slopes.

[0003] Currently, traditional slopes often adopt two greening methods:

[0004] Firstly, the slope is greened by using the technology of soil spraying and seeding. Although this greening method can cover the slope surface in the short term, its soil matrix is unstable, and the rooting effect of green plants is not ideal, so it is impossible to form a stable and lasting greening structure on rocky slopes.

[0005] Secondly, vegetation concrete is filled on the slope. Although this greening method can provide a growth basis for plants, due to the large self-weight of the vegetation concrete, it is difficult to construct on steep rocky slopes, and the construction method of the vegetation concrete is complex and the production cost is high, which is not conducive to cost control. Summary of the Invention

[0006] The purpose of the utility model is to provide a greening structure applicable to the space between frames on high-steep rocky slopes, which has remarkable greening effects and good long-term stability, and is fast in construction and low in construction cost.

[0007] The purpose of the utility model is realized through the following technical solutions:

[0008] A greening structure applicable to the space between frames on high-steep rocky slopes, which comprises a concrete grid beam poured along the slope surface of the steep slope, and the concrete grid beam comprises several grid units;

[0009] The soil area corresponding to the hollowed position of each grid unit is covered with a base mesh, and a grass seed mixed substrate is sprayed on the base mesh;

[0010] A number of support rods arranged in a rectangular array or horizontally linearly are inserted on the base mesh, and a vegetation rod is also erected on the support rods at the same height.

[0011] Compared with the prior art, the advantages of the utility model are as follows:

[0012] 1. By arranging support rods, a base mesh and a grass seed mixed substrate in the grid unit, the greening vegetation has a stable growth matrix on the rocky slope and can take root well, realizing remarkable greening of the high-steep rocky slope;

[0013] 2. Through the cooperation of the vegetation planting rods and the support rods, the grid units are divided into multiple spaces with the vegetation planting rods as the boundaries, effectively preventing the loss of the grass seed mixed substrate due to gravity and erosion. Moreover, the vegetation planting rods can also serve as the attachment points for the early growth of the grass seed mixed substrate, effectively improving the success rate of the grass seed mixed substrate growing into green plants and enhancing the stability of the overall greening structure.
