Description

Technical Field

[0001] This utility model relates to the field of mine ecological restoration technology, specifically to an ecological greening wall for steep rocky slopes in mines. Background Technology

[0002] During the mining process, open-pit mines will form multiple levels of steep rock slopes. Due to the steepness of the rock walls, it is difficult for soil to support the growth of vegetation during the mine restoration process, which has always been a difficult problem affecting the effectiveness of mine ecological restoration.

[0003] Currently, mine slope restoration mainly employs methods such as hydroseeding, climbing plants, and vegetation trenches (holes). However, existing restoration technologies have several shortcomings: hydroseeding is suitable for gentle slopes, but on steep slopes, soil and seeds are easily washed away by rainwater, resulting in low survival rates; climbing plants grow slowly, have long maintenance cycles, and show results in a short period; vegetation trench (hole) construction is relatively scattered, resulting in a small actual revegetated area and poor overall revegetation effect. Furthermore, existing restoration devices have poor adaptability and cannot be flexibly adjusted according to different slope gradients and soil properties, making it difficult to meet actual needs in terms of restoration effect and efficiency.

[0004] Therefore, there is an urgent need to design an ecological greening wall for steep rocky slopes in mines that takes into account both the stability of the soil covering structure and the effect of ecological restoration, in order to solve the problems existing in the current technology. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an ecological greening wall for steep rocky slopes in mines, which can not only effectively improve the stability of the soil covering structure of the slope, but also quickly realize the ecological greening of the slope. It is also highly adaptable and can be adjusted according to different slope conditions.

[0006] The technical solution provided by this utility model is as follows: an ecological greening wall for steep rock slopes in mines, comprising a crushed stone cushion layer and hollow blocks. The ecological greening wall is constructed by staggered joints of hollow blocks along the crushed stone cushion layer at the foot of the steep slope, with the blocks and the rock walls bonded together by glutinous rice mortar. Each hollow block contains a planting substrate soil, which consists of a fertilizer and water retention layer and a rooting layer for vegetation, from the inside out.

[0007] Furthermore, each hollow block has drainage grooves on its upper and lower surfaces, is filled with vegetation substrate soil, and has a sponge cover on its surface.

[0008] Furthermore, the raised grooves on both sides of the sponge cover are embedded in the drain hole.

[0009] Furthermore, the crushed stone cushion layer is constructed at the toe of the slope using a dry-masonry method, and is trapezoidal in shape. The cushion layer on the side closest to the slope surface remains perpendicular to the slope surface.

[0010] Furthermore, the hollow blocks are made from straw, raw soil, lime, kaolin, silica sol and sodium stearate through raw material mixing, molding and natural drying.

[0011] Furthermore, the glutinous rice mortar is prepared by mixing quicklime and glutinous rice paste in a mass ratio of 6:4.

[0012] Furthermore, the fertilizer-replenishing and water-retaining layer is composed of vermiculite and perlite mixed in a 1:1 mass ratio, with added solid nitrogen, phosphorus, and potassium, and has a thickness of 5-8 cm.

[0013] Furthermore, the root layer of the vegetation is composed of a mixture of nutrient-rich planting soil and grass, shrubs and seeds, with a thickness of 20-25 cm.

[0014] Furthermore, the seeds are selected from herbaceous plants or shrubs suitable for the climate and soil conditions, and are buried in the upper part of the vegetation layer.

[0015] The beneficial effects of this utility model are:

[0016] (1) This utility model builds an ecological wall close to the surface of a rocky steep slope, creating a space for vegetation growth on the steep slope. Compared with traditional methods, it increases the area and effect of greening the rocky steep slope. At the same time, the continuous laying of the retaining wall isolates the rocky slope from further erosion and weathering by wind and rain, which can improve the stability of the slope and avoid geological disasters such as slope collapse.

[0017] (2) The masonry materials selected in this utility model are all biodegradable and pollution-free materials. They will gradually degrade as the vegetation grows, and the final effect of the revegetation is more similar to natural restoration.

[0018] (3) This utility model has a simple structure, is easy to install, and has a low cost after being scaled up. It takes into account both the stability of the slope structure and the ecological restoration effect, and has high practicality and promotion value. Attached Figure Description

[0026] like Figure 1-3 The diagram shows an ecological greening wall on a steep rocky slope in a mine, comprising a crushed stone cushion layer 1 and hollow blocks 2. The ecological greening wall is constructed by gradually assembling the hollow blocks 2 along the crushed stone cushion layer 1 at the foot of the steep slope, with staggered joints. The blocks and the rock walls are bonded together with glutinous rice mortar. Each hollow block 2 contains a vegetation substrate soil 3, which consists of a fertilizer and water retention layer 301 and a vegetation root layer 302 from the inside out.

[0027] Each hollow block 2 has drainage channels 201 on its upper and lower surfaces, and is filled with vegetation substrate soil 3. A sponge cover 4 is provided on the surface of the hollow block 2. The raised grooves on both sides of the sponge cover 4 are embedded in the drainage channels 201 to prevent soil erosion.

[0028] The crushed stone pad 1 is dry-laid at the toe of the slope, forming a trapezoidal shape. The pad layer on the side closest to the slope surface is perpendicular to the slope surface to ensure that the blocks adhere tightly to the steep rock slope surface during construction, providing support for the hollow blocks 2 at the bottom. After the hollow blocks 2 are filled with vegetation substrate soil 3, the protrusions on the upper and lower sides of the sponge cover plate 4 are inserted into the drainage groove holes 201 of the hollow blocks for fixation. After completion, the blocks are laid step by step along the slope until the construction height is reached, thus completing the construction of the ecological revegetation device for the steep rock slope. The adhesive material used between the blocks and between the blocks and the rock walls is glutinous rice mortar (prepared by mixing quicklime and glutinous rice mortar in a mass ratio of 6:4). The blocks are laid with staggered joints between the upper and lower layers.

[0029] The hollow block 2 is made from straw, raw soil, lime, kaolin, silica sol, and sodium stearate through a mixture of raw materials, mold pressing, and natural drying. In a specific embodiment, the mass fractions of each component are as follows: straw 16%-20%, raw soil 30%-34%, lime 18-20%, kaolin 16-20%, silica sol 15-18%, and sodium stearate 0.2-1%.

[0030] The vegetative substrate soil 3 is embedded in the hollow block 2 with a layered structure. From the inside out, it consists of a fertilizer and water retention layer 301 and a vegetation root layer 302. The fertilizer and water retention layer 301 is made of vermiculite and perlite mixed in a 1:1 mass ratio, with 2% solid nitrogen, phosphorus, and potassium added. It is 5-8 cm thick and is laid at the bottom of the hollow block 2. The vegetation root layer 302 is composed of nutrient planting soil mixed with grass, shrub, and seed. The seeds are selected from herbaceous plants (such as alfalfa and bermudagrass) or shrubs (such as purple locust and sea buckthorn) suitable for local climate and soil conditions. The vegetation seeds are buried in the upper part of the layer and are about 20-25 cm thick, laid on top of the fertilizer and water retention layer 301 in the hollow block 2.

[0031] The installation process of this utility model is as follows:

[0032] (1) Fill the hollow block 2 with the vegetative substrate soil 3 layer by layer according to the thickness requirements of the fertilizer and water retention layer 301 and the root layer 302. After flattening and compacting, insert the upper and lower protrusions of the sponge cover plate 4 into the drainage groove hole 201 of the hollow block 2 for fixing, and complete the preparatory work before block construction.

[0033] (2) Before the masonry construction, the steep rock slope is cleaned and the loose rock and soil on the surface is removed;

[0034] (3) Level the slope toe appropriately, and dry-build the crushed stone cushion layer 1 along the slope toe as a whole, and build the ecological green wall by staggering the joints in step by step to fit the slope surface.

[0035] (4) After the masonry is completed, the wall surface is moistened with water and the water leakage between the upper and lower masonry blocks is checked.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
