[0002] Ecological restoration is a process that promotes the self-restoration and regeneration of damaged ecosystems through artificial intervention. This method aims to help those ecosystems that have been damaged by natural disasters, human activities or environmental changes to gradually restore to their original healthy state or a state close to nature through a series of scientific, reasonable and targeted measures. Side slope ecological restoration net is an engineering technical measure specially designed for side slope protection and ecological restoration, which fixes plant seeds, soil conditioners and necessary nutrients on a specially designed net structure, and then lays it on the damaged side slope to promote the rapid growth of vegetation and the stabilizing effect of root system. This method not only helps to prevent soil erosion, but also gradually restores the ecological function of the side slope.

The upper hanging net body 2, the vegetation layer 4 and the bottom hanging net body 5 are fixed on the slope body 3 through a plurality of fixed mechanisms 1.

[0020] The upper hanging net body 2 includes an upper layer hanging net 202, which is a bag-shaped structure. The top and bottom surfaces of the upper layer hanging net 202 are provided with a plurality of fixed holes 201, and the inside is fixedly filled with first water-absorbing cotton 203.

[0021] The bottom hanging net body 5 includes a bottom layer hanging net 504, which is also a bag-shaped structure. The top and bottom surfaces of the bottom layer hanging net 504 are provided with a plurality of mesh holes 502, and the inside is fixedly filled with second water-absorbing cotton 503.

[0022] Specifically, the first water-absorbing cotton 203 is fixed inside the upper layer hanging net 202, which is used to keep the moisture and provide additional water supply for the vegetation. The fixed holes 201 on the outside have good air permeability, and the fixed holes 201 allow air to circulate, which is conducive to promoting the healthy growth of plants. The second water-absorbing cotton 503 inside the bottom layer hanging net 504 can absorb and store rainwater, and then slowly release it to the vegetation layer 4 through the mesh holes 502, promoting the growth of vegetation. In addition, the plants in the vegetation layer 4 can grow through the mesh holes 502, and their root systems can penetrate through the mesh holes 502 into the soil, enhancing the stability of the slope body 3. The first water-absorbing cotton 203 and the second water-absorbing cotton 503 can uniformly distribute and penetrate water into the vegetation layer 4, without the need for separate installation of water-absorbing and blocking devices, thereby improving the water retention and drought resistance of the vegetation layer 4, forming stable vegetation coverage, and further reinforcing the mountain slope and reducing the risk of erosion as the vegetation root system develops. Not only does it achieve the stability of the slope body 3, but also promotes the growth of vegetation through water management, providing strong support for the ecological restoration of the slope.

[0023] Preferably, the fixing mechanism 1 comprises a fixing column 101, a bolt 104 and two fixing blocks 103, the fixing column 101 is a hollow structure with an open top end, two through holes for the fixing blocks 103 to pass outwards are oppositely arranged on the side wall of the fixing column 101, the two fixing blocks 103 are slidingly arranged in the two through holes respectively and are connected to the fixing column 101 through the springs 102 respectively, the fixing column 101 is inserted into the bottom hanging net body 5 and the slope body 3, the rod of the bolt 104 passes through the upper hanging net body 2 and the vegetation layer 4 from top to bottom in sequence and is threadedly connected to the inside of the fixing column 101, and the front end of the rod of the bolt 104 is in inclined surface cooperation with the two fixing blocks 103, when the bolt is screwed to move downwards, the bolt 104 can extrude the two fixing blocks 103 to the two sides, so that the two fixing blocks 103 move outwards respectively and are embedded in the inside of the slope body 3.

[0024] Preferably, the bottom of the fixing column 101 is conically arranged, and the top of the fixing column 101 is provided with a flange for abutting against the top surface of the vegetation layer 4.

[0025] Preferably, the spring 102 is sleeved on the fixing block 103, the outer end of the spring 102 is fixed to the inner wall of the fixing column 101, and the inner end of the spring 102 is fixed to the fixing block 103.

[0026] Specifically, in the process of ecological restoration of the mountain slope, the slope body 3 is cleaned first, then the bottom hanging net body 5 is laid on the cleaned slope body 3 to ensure that it is closely attached to the slope surface, then the bottom hanging net body 5 is fixed on the slope body 3 by the fixing column 101 to achieve preliminary stability, then the vegetation layer 4 is laid above the bottom hanging net body 5, and the upper hanging net body 2 is covered thereon to protect the vegetation layer 4, when the bolt 104 moves in the fixing column 101, the lower end of the bolt 104 will push the fixing block 103 to make the fixing block 103 slide outwards, the spring 102 plays a connecting role, the outward sliding of the fixing block 103 will compress the spring 102 to make it shrink in the fixing column 101, and the outward sliding of the fixing block 103 will be closely embedded in the slope body 3, so that the whole restoration net is firmly fixed on the slope body 3, the overall stability is improved, the water and soil loss is effectively reduced, and the surrounding ecological environment is positively improved.

[0027] Preferably, the top surface and the bottom surface of the bottom hanging net 504 are both fixedly provided with a row of barbs 501 outwards, the row of barbs 501 on the bottom surface is clamped in the slope body 3, and the row of barbs 501 on the top surface is clamped in the vegetation layer 4. The bottom hanging net body 5 further increases the friction with the slope body 3 through the plurality of barbs 501, and can prevent the soil in the vegetation layer 4 from sliding down due to gravity or external force, thereby maintaining the integrity and stability of the slope body 3.

[0028] Working principle: when repairing the ecology of the mountainous slope, first, the slope body 3 is cleaned, then the bottom hanging net body 5 is laid on the slope body 3, then it is fixed on the slope body 3 through the fixed column 101, then the vegetation layer 4 and the upper hanging net body 2 are laid, then they are threadedly connected with the fixed column 101 through the bolt 104, when the bolt 104 moves inside the fixed column 101, it will gradually push the fixed block 103 to move outward (here, it refers to the direction perpendicular to the bolt 104), the outward movement of the fixed block 103 will gradually embed into the slope body 3, thus firmly fixing the whole slope repairing structure on the slope body 3;

[0029] Secondly, when it rains, the rainwater can be absorbed by the first water-absorbing cotton 203 and then slowly released, providing a continuous water supply for the plants in the vegetation layer 4, the barbs 501 of the bottom layer hanging net 504 play a fixing role, can fix the bottom hanging net body 5 on the slope body 3, at the same time, can prevent the soil in the vegetation layer 4 from sliding downward under the action of gravity or external force, the mesh holes 502 in the bottom layer hanging net 504 can not only allow part of the soil particles in the slope body 3 to exchange materials with the vegetation layer 4, but also can block the loss of larger particles to a certain extent, the second water-absorbing cotton 503 in it can absorb the water in the slope body 3 and then provide water for the vegetation layer 4 when needed, especially in the area with higher water content in the slope body 3 to the vegetation layer 4.
