FIG. 1 is a layout diagram of a mesh service;

FIG. 2 is a schematic view of the first anchor and planting pit;

fig. 3 is a schematic view of the second anchor and planting pit.

Detailed Description

The vegetation restoration system for the large-gradient land as shown in figure 1 comprises a net-shaped enclosure 1 laid on the surface of a slope. The net-shaped enclosure 1 comprises net wires 2 which enclose polygonal meshes which can be rectangular meshes, parallelogram meshes or triangular meshes. Each end point forming each mesh is respectively connected with an anchor rod, each anchor rod is respectively anchored on planting pits 3 with different slope bodies, and soil is filled in each planting pit 3. These planting holes 3 are dug in advance on the slope body, and are used for planting grass seeds.

In an embodiment, the anchor rods have a plurality of anchor rods, each anchor rod comprises a first anchor rod and a second anchor rod which are arranged in a staggered mode, the first anchor rod is provided with a water transfer structure, and the water transfer direction of the water transfer structure is from a deep layer of the slope body to the surface of the slope body. The water transfer structure can lead out the moisture in the deep layer of the slope body to the surface, so that the moisture is supplemented to the surface of the slope body and the soil close to the surface of the slope body, and the normal growth of grass seeds is guaranteed.

Specifically, referring to fig. 2, the first anchor rod includes a hollow rod body 4 and a plurality of water permeable holes 5 formed in the surface of the rod body 4, the hollow portion in the rod body 4 is filled with a water absorbing material 6, the water permeable holes 5 are communicated with the water absorbing material 6, and the water permeable holes 5 are arranged along the length direction of the rod body 4. The water body firstly enters the water permeable holes 5 from the deep layer of the slope body and is absorbed by the water absorbing material 6, then is transferred to the surface of the slope body through the water absorbing material 6, and then the relatively dry soil body on the surface of the slope body or close to the surface of the slope body absorbs water from the water absorbing material 6 for the growth of grass seeds. The water absorbing material 6 may be sawdust.

Further preferably, referring to fig. 2 and 3, the soil body comprises organic soil 7 and covering soil 8 which are stacked from the deep layer of the slope body to the surface of the slope body, and the covering soil 8 is mainly used for covering grass seeds. The first anchor rod penetrates through the covering soil 8 and the organic soil 7 in sequence and is connected to the deep layer of the slope body. The water permeable holes 5 of the first anchor rod correspond to the positions of the soil cover 8, the organic soil 7 and the deep layer of the slope body respectively, so that the organic soil 7 and the soil cover 8 can absorb water from the deep layer. The top of the first anchor rod is exposed from the surface of the slope body and is used for connecting the mesh wire 2.

Preferably, the second anchor rod is a solid anchor rod, and the structural strength of the second anchor rod is high.

In one embodiment, the first anchor rods and the second anchor rods are arranged in a staggered mode along the inclination direction of the slope body, namely the first anchor rods are arranged in the first row, the second anchor rods are arranged in the second row, the first anchor rods are arranged in the third row, and the like.

In another embodiment, the first anchor rods and the second anchor rods are staggered along the inclination direction of the slope body and the width direction of the slope body. The first anchor rod is adjacent to the second anchor rod in front of, behind, on the left and on the right, so that the uniformity of water absorption is ensured.

Further preferably, the net wire 2 is made of degradable material, and can be automatically degraded after the vegetation is restored without manual treatment.

Further preferably, referring to fig. 3, the second anchor rod includes a locking rod 9, an openable non-return side wing 10 is hinged to an outer wall of the locking rod 9, an opening direction of the non-return side wing 10 is toward a surface of the slope body, an elastic component 11 is connected to a middle portion of the non-return side wing 10, the elastic component 11 is connected to the outer wall of the locking rod 9, and the elastic component 11 is a spring. When the second anchor rod is driven into the planting pit 3, the non-return side wing 10 is folded due to resistance, after the anchoring is in place, the non-return side wing 10 is slowly opened, the rock soil body above the non-return side wing generates downward pressure on the non-return side wing 10, the friction force of the non-return side wing 10 is matched, the second anchor rod is not easy to be separated upwards, and the anchoring stability is greatly improved.

In an embodiment not shown, the second anchor may also be an expansion screw.

The above description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.
