Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, in particular to a protection net for green ecological restoration of mines. Background Art

[0002] For the high and steep slopes on both sides of the roads in the mining area, if engineering measures are not taken, it will be difficult for the plant growth matrix to attach to the slope surface and the plants will not be able to grow. Therefore, vegetation slope protection technology must be a combination of plant measures and engineering measures to effectively solve the problems of slope engineering protection and ecological environment protection, which not only ensures the stability of the slope, but also achieves the rapid recovery of slope vegetation.

[0003] In the restoration of the green ecological environment of the mine slope, the stability of the soil on the slope must be ensured to avoid excessive loss in order to ensure the stable growth of vegetation. At present, in the protection of slope soil and vegetation, more protection nets are used to cover the slope for protection, and they are single-layer protection nets. In this way, the protection net only covers the surface of the slope and is easy to fall off the slope, causing the protection net to lose the protection of the slope and the green ecological environment. Therefore, it is necessary to design a protection net for mine green ecological restoration. Utility Model Content

[0004] The purpose of the utility model is to provide a protective net for green ecological restoration of mines in order to solve the above problems.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] See also Figure 1-2 A protective net for green ecological restoration of mines, comprising a bottom strip protective net 1 and a top strip protective net 2, both of which are unfolded along the slope surface of the slope and fixed on the slope, which is equivalent to laying one end of the bottom strip protective net 1 and the top strip protective net 2 from the top of the slope to the bottom of the slope, and horizontally, the bottom strip protective net 1 and the top strip protective net 2 are continuously spliced ​​to fully cover the direction of the slope;

[0024] The bottom belt-shaped protection net 1 is arranged below the top belt-shaped protection net 2;

[0025] The bottom strip protection net 1 is pre-buried under the soil layer on the slope surface and extends in a wave shape;

[0026] The top layer of belt-shaped protection net 2 is laid on the surface of the slope and is extended in a wave shape symmetrical to the bottom layer of belt-shaped protection net 1;

[0027] The bottom strip protection net 1 and the top strip protection net 2 are symmetrically distributed to form a continuous space for wrapping the soil layer on the surface of the slope, and then the wrapped soil has a suppressing effect on the bottom strip protection net 1, preventing the protection net from falling off the slope, and thus better preventing soil erosion on the slope, so as to better carry out green ecological restoration of the mine.

[0028] Furthermore, the wavy structures of the bottom belt protection net 1 and the top belt protection net 2 both have crests and troughs. The crests of the bottom belt protection net 1 face downward and the troughs face upward, while the crests of the top belt protection net 2 face upward and the troughs face downward, which are mirror-symmetrical to the bottom belt protection net 1. This makes the troughs of the bottom belt protection net 1 contact with the troughs of the top belt protection net 2, and the soil pressed on the bottom belt protection net 1 is equivalent to backfilling above the crests of the bottom belt protection net 1, thereby suppressing the bottom belt protection net 1.

[0029] Furthermore, the trough position where the bottom belt protection net 1 and the top belt protection net 2 contact each other is fixed on the slope by setting a first anchor nail 3. The first anchor nail 3 passes through the bottom belt protection net 1 and the top belt protection net 2 and is nailed under the surface of the slope, thereby fixing the bottom belt protection net 1 and the top belt protection net 2 at the same time through the first anchor nail 3.

[0030] Furthermore, a second anchor nail 4 is provided at the crest position of the bottom belt protection net 1, and the second anchor nail 4 is nailed into the slope to press the bottom belt protection net 1 against the slope. While the second anchor nail 4 fixes the bottom belt protection net 1, it also plays a better role in maintaining and fixing the shape of the crest position of the bottom belt protection net 1 due to its fixed position.

[0031] Furthermore, an extension rod 5 is coaxially connected to the end of the second anchor nail 4 opposite to the end that is nailed into the slope, and a support plate 6 is provided on the end of the extension rod 5 opposite to the second anchor nail 4 to lift the top layer of belt protection net 2 upwards and separate it from the bottom layer of belt protection net 1, so as to maintain the space formed between the top layer of belt protection net 2 and the bottom layer of belt protection net 1, so as to better load backfill soil to suppress and fix the bottom layer of belt protection net 1.

[0032] To sum up, the device sets two layers of protection nets, a bottom strip protection net and a top strip protection net, on the slope, and covers the bottom strip protection net with backfill soil, then covers the surface of the slope with the top strip protection net, and fixes the two layers of protection nets on the slope. This structure not only ensures the stability of the protection net on the slope and prevents the protection net from falling off the slope, but also further protects the soil and vegetation on the slope, better avoids soil erosion and the resulting damage to green vegetation, and thus can better implement the restoration of the green ecology of the mine.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
