Description

Technical Field

[0002] Slope engineering is one of the most common types of engineering in the field of geotechnical engineering. Slope support is a retaining, reinforcement and protection measure taken for slopes to ensure the safety of slopes and their environment. For rock high slopes, the form of anchor (lock) lattice beams is often used. Before the lattice beams, the rock surface is exposed. To meet the requirements of ecological greening, various slope surface ecological protection means are adopted for the exposed rock surface, such as soil spraying technology, ecological bag paving and greening technology, vegetation blanket protection technology, net spraying technology, etc. The soil spraying technology has obvious advantages and is widely used, but the sprayed soil is easily washed away by rainwater, resulting in serious loss of slope surface soil and poor slope surface greening effect. The soil on the slope surface of soil spraying is seriously lost, and the growth condition of plants is not good.

[0003] Therefore, an ecological slope protection structure for the slope surface of lattice beam slopes that can solve the above problems is needed. Summary of the Invention

[0024] Embodiment: As Figures 1 to 5As shown in the figure, this embodiment relates to an ecological protection structure for the slope surface of a lattice beam revetment, which mainly includes a lattice beam revetment and a slope surface 2 of sowing and spraying soil. There is a lattice beam 1 on the slope surface 3 of the lattice beam revetment. The slope surface 2 of sowing and spraying soil is arranged on the slope surface within the lattice formed by the lattice beam 1 of the lattice beam revetment. Vegetation 4 is planted on the slope surface 2 of sowing and spraying soil, and the slope surface 2 of sowing and spraying soil can ensure the good growth of the vegetation 4.

[0025] As Figures 1 to 5 shown, the slope surface 2 of sowing and spraying soil includes short anchor rods 21, a steel mesh 22, straw mats, a fixing mesh 25 and soil for sowing and spraying 26. The short anchor rods 21 are vertically anchored on the slope surface 3 of the lattice beam revetment. 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. And because the intersection of the short anchor rods 21 and the steel bars of the steel mesh 22 is fixed, the fixing of the steel mesh 22 to the straw mat can be realized. The fixing mesh 25 is connected to the steel mesh 22 by steel wires. The soil for sowing and spraying 26 wraps the short anchor rods 21, the steel mesh 22, the straw mat and the fixing mesh 25, thus forming the slope surface 2 of sowing and spraying soil. The mesh holes of the fixing mesh 25 are arranged in a diamond shape on the slope surface 3 of the lattice beam revetment. The mesh holes of the steel mesh 22 are arranged in a square shape on the slope surface 3 of the lattice beam revetment, which is convenient for stabilizing the soil for sowing and spraying 26 and beneficial to the growth of the vegetation 4. In addition, at the intersection of the lattice beams 1, there are anchor rods 12 (or anchor locks). The inner end of the anchor rod 12 (or anchor lock) extends into the lattice beam revetment, and the outer end of the anchor rod 12 (or anchor lock) is locked and fixed by an anchor rod lock head 11 (or an anchor lock lock head).

[0026] As Figures 1 to 5 shown, this embodiment also has a construction method. After the slope surface 3 is leveled, the ecological protection structure for the slope surface of the lattice beam revetment is constructed, and its construction steps are specifically as follows:

[0030] 4. Construct the steel mesh 22. The steel mesh 22 is made of 10# steel bars, with an interval of 35 - 40 cm. The intersection position of the steel mesh 22 is firmly fixed to the short anchor rods 21. At the same time, the steel mesh 22 firmly fixes the horizontal straw mat 23 and the vertical straw mat 24 on the slope surface 3. Then, the fixing mesh 25 is firmly fixed to the steel mesh 22 with steel wires.

[0031] 5. Produce the imported soil 26, which includes a general base material mixture and a base material mixture containing grass seeds. First, spray 8 cm of the general base material mixture, and then spray 2 cm thick of the base material mixture containing grass seeds.

[0032] 6. Maintain and spray the slope surface 2 of the imported soil. Eventually, vegetation 4 grows on the slope surface 2 of the sprayed imported soil.

[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 grid beam slope surfaces.

[0037] 4. Both the fixing net and the straw mats can stabilize the imported soil, enabling the imported soil to be better retained on the slope surface.
