[0002] Slope engineering is one of the most common types of engineering in the field of geotechnical engineering. Slope support refers to the retaining, reinforcement and protection measures taken for slopes to ensure the safety of slopes and their environments. For rocky slopes, due to good slope stability, natural slope forms are often adopted. To meet the requirements of ecological greening, various slope ecological protection means are adopted for the exposed rock surfaces formed by natural slopes, such as soil spraying on slope surface with vegetation soil technology, ecological bag paving and greening technology, vegetation blanket protection technology, net spraying technology, etc. The soil spraying on slope surface with vegetation soil technology has obvious advantages and is widely used, but the sprayed vegetation soil is easily washed away by rainwater, resulting in serious loss of vegetation soil on the slope surface, and then poor greening effect on the slope surface. Especially for rocky slopes with large slopes, the applicability of soil spraying on slope surface with vegetation soil is poor. The loss of soil on the slope surface of soil spraying on slope surface with vegetation soil is serious, and the growth condition of plants is not good.

[0007] The end of the steel mesh extends into the drainage ditch to form a steel mesh anchorage section; the end of the fixing net extends into the drainage ditch to form a fixing net anchorage section.

[0021] The features of the present utility model and other related features will be further described in detail below with reference to the accompanying drawings through embodiments for the understanding of those skilled in the same industry:

[0024] Embodiment: As Figures 1 to 5As shown in the figure, this embodiment relates to a slope protection structure for soil spraying, which mainly includes a slope, a drainage ditch 11, and a soil spraying slope 1. The slope is stepped. The drainage ditch 11 is arranged on the flat surface of the slope for drainage. The soil spraying slope 1 is arranged on the excavated surface 3 of the slope to ensure the good growth of plants.
[0025] As Figures 1 to 5 shown, the soil spraying slope 1 includes short anchor bolts 21, a steel mesh 22, a straw mat, a fixing mesh 25, and soil 26. The short anchor bolts 21 are vertically anchored on the excavated surface 3 of the slope. The straw mat is composed of a horizontal straw mat 23 and a vertical straw mat 24. A grid is formed between the horizontal straw mat 23 and the vertical straw mat 24. The fixing mesh 25 is installed in the grid. The steel mesh 22 covers the straw mat. Since the intersection of the steel bars of the short anchor bolts 21 and the steel mesh 22 is fixed, the steel mesh 22 can fix the straw mat. The fixing mesh 25 is connected to the steel mesh 22 by steel wires. The soil 26 wraps the short anchor bolts 21, the steel mesh 22, the straw mat, and the fixing mesh 25. The mesh holes of the fixing mesh 25 are arranged in a diamond shape on the excavated surface 3 of the slope, and the mesh holes of the steel mesh 22 are arranged in a square shape on the excavated surface 3 of the slope, which is convenient for stabilizing the soil 26 and beneficial to the growth of plants. In addition, the end of the steel mesh 22 extends into the drainage ditch 11 to form a steel mesh anchorage section 221; the end of the fixing mesh 25 extends into the drainage ditch 11 to form a fixing mesh anchorage section 251.
[0026] As Figures 1 to 5 shown, this embodiment also has a construction method. After the excavated surface 3 is leveled, the slope protection structure for soil spraying is constructed. The specific construction steps are as follows:
[0027] To construct the soil spraying slope 1, first drill holes on the excavated surface 3 and construct the short anchor bolts 21, and the short anchor bolts 21 are perpendicular to the excavated surface 3.
[0028] Lay the vertical straw mat 24, the vertical straw mat 24 is 5 cm thick, 10 cm wide, and arranged at an interval of 1 m; then lay the horizontal straw mat 23, the horizontal straw mat 23 is 8 cm thick, 15 - 20 cm wide, and arranged at an interval of 1 m.
[0029] Lay the fixing mesh 25 between the straw mats. The fixing mesh 25 is made of 8# galvanized iron wire mesh, with mesh holes of 5 cm × 5 cm. The mesh holes are arranged in a diamond shape on the excavated surface 3. The fixing mesh 25 should extend into the drainage ditch 11 to form an anchorage section, and the length of the fixing mesh anchorage section 251 is 10 cm.
[0030] Construct the steel mesh 22. The steel mesh 22 is made of 10# steel bars with a spacing of 35 - 40 cm. The intersection positions of the steel mesh 22 are firmly fixed to the short anchor bolts 21. At the same time, the steel mesh 22 firmly fixes the horizontal straw mats 23 and the vertical straw mats 24 to the excavation surface 3. Then, the fixing net 25 is firmly fixed to the steel mesh 22 with steel wires. The steel mesh 22 should extend into the drainage ditch 11 to form an anchorage section, and the length of the steel mesh anchorage section 221 is 15 cm.
[0031] Produce the vegetative soil 26. The vegetative soil 26 includes a common base material mixture and a base material mixture containing grass seeds. First, spray the common base material mixture with a thickness of 8 cm, and then spray the base material mixture containing grass seeds with a thickness of 2 cm.
[0032] Maintain the slope surface 1 of the vegetative soil spraying. Eventually, vegetation grows on the slope surface 1 of the vegetative soil spraying.
[0033] The beneficial technical effects of this embodiment are as follows:
[0034] 1. The use of horizontal straw mats and vertical straw mats can effectively improve the situation of vegetative soil loss on steep rock slope surfaces and ensure good growth of plants.
[0035] 2. The straw mats are cheap, made of natural rice straws, environmentally friendly, and will not cause pollution to the environment.
[0036] 3. The structural form is simple, the materials are convenient to purchase, the construction is fast, and it can be widely applied to the ecological protection of natural slope surfaces.
[0037] 4. Both the fixing net and the straw mats can stabilize the vegetative soil, enabling the vegetative soil to be better retained on the slope surface.
[0038] Although the above embodiments have detailed the concept and implementation of the purpose of the present invention with reference to the drawings, those of ordinary skill in the art can recognize that various improvements and transformations can still be made to the present invention without departing from the scope defined by the claims.
