Description

Technical Field

[0001] The utility model relates to the technical field of soil and water conservation in wind farms, in particular to a soil and water conservation ecological slope protection. Background Art

[0002] A wind farm, also known as a wind power plant, refers to the installation of multiple grid-connected wind turbines in a site with good wind resources. Generally speaking, the steeper and more open the terrain, the stronger the wind. At the same time, it is necessary to select a place with sufficient wind speed and stable wind direction. Steep mountains rarely have flat land suitable for the installation of wind turbines, so land leveling and infrastructure construction are required, and soil and water conservation construction is also required at the site of the wind farm.

[0003] The existing soil and water conservation ecological slope protection only installs frames, slope protection bricks or nets on the land surface, which cannot effectively guide surface runoff and significantly reduce the soil and water loss caused by surface runoff. The retaining structure at the bottom of the slope is simple and cannot effectively discharge the accumulated surface runoff. At the same time, the artificial traces are obvious, which is not conducive to ecological restoration. In view of the above problems, an innovative design is carried out on the basis of the original soil and water conservation ecological slope protection. Utility Model Content

[0009] Preferably, the front view cross-section of the platform drainage ditch is a "concave" shape, and the platform drainage ditch is symmetrically distributed about the center of the side drainage ditch.

[0010] Preferably, the mortar-laid stone slag retaining walls are densely distributed at equal intervals, the front view cross-sectional shape of the upper middle portion of the mortar-laid stone slag retaining wall is a right-angled trapezoid, and the bottom surface of the mortar-laid stone slag retaining wall is set as an inclined surface.

At the same time, the drainage pipes and filter layers densely arranged at equal intervals on the mortar-made stone slag retaining walls are used to discharge the accumulated surface runoff and prevent soil loss.

[0029] See also Figure 1-4 The utility model provides a technical solution: a soil and water conservation ecological slope protection, including an original soil layer 1, a construction slag body 2, a compacted slope surface 3, a planting covering soil 4, a protective net 5, a platform drainage ditch 6, a side drainage ditch 7, a bottom step 8, a mortar-laid stone slag retaining wall 9, a bottom anchor 10, a drainage pipe 11, an inverted filter layer 12, a top drainage ditch 13, a top covering soil 14 and a mortar-laid stone drainage ditch 15, the original soil layer 1 is covered with the construction slag body 2, a compacted slope surface 3 is arranged on the top of the construction slag body 2, a planting covering soil 4, a platform drainage ditch 6 and a side drainage ditch 7 are arranged on the surface of the compacted slope surface 3, and a protective net 5 is fixedly installed on the surface of the planting covering soil 4;

[0030] The end of the platform drainage ditch 6 is connected to the side of the side drainage ditch 7. A bottom step 8 is provided on the inner bottom surface of the side drainage ditch 7. A mortar-laid stone slag retaining wall 9 is provided at the bottom end of the side drainage ditch 7 and the construction slag body 2. A bottom anchor 10 is provided at the bottom end of the mortar-laid stone slag retaining wall 9. The bottom anchor 10 is connected to the original soil layer 1. A drainage pipe 11 is fixedly passed through the middle of the mortar-laid stone slag retaining wall 9. A filter layer 12 is installed near the end of the drainage pipe 11 near the construction slag body 2.

[0031] The top of the compacted slope 3 is connected to one side of the top drainage ditch 13 , and a top covering soil 14 is arranged on the surface of the construction residue body 2 on the other side of the top drainage ditch 13 , and a mortar-laid stone drainage ditch 15 is installed at the end of the top covering soil 14 .

[0032] In this example, the planting covering soil 4 and the platform drainage ditch 6 are distributed at intervals on the surface of the compacted slope 3, and the compacted slope 3 is in a segmented stepped shape. The above structural design can prevent the continuous flow and convergence of surface runoff along the hillside, and intercept and guide the surface runoff through the platform drainage ditch 6.

[0033] The platform drainage ditch 6 in this example has a concave cross-section when viewed from the front, and is symmetrically distributed about the center of the side drainage ditch 7. The above structural design enables the platform drainage ditch 6 to guide the cut-off slope surface runoff to the side drainage ditch 7 for centralized discharge.

[0034] The mortar-made stone slag retaining wall 9 in this example is densely distributed with equal intervals, the front view cross-section of the upper and middle parts of the mortar-made stone slag retaining wall 9 is a right-angled trapezoid, and the bottom surface of the mortar-made stone slag retaining wall 9 is set as an inclined surface. The above-mentioned structural design ensures the blocking effect of the mortar-made stone slag retaining wall 9, so that the mortar-made stone slag retaining wall 9 will not collapse.

[0035] In this example, bottom anchors 10 are fixed at equal intervals at the bottom end of the mortar-made stone slag retaining wall 9, and the length of the bottom anchors 10 is not less than 1 / 5 of the overall height of the mortar-made stone slag retaining wall 9. The above-mentioned structural design further ensures the stability of the mortar-made stone slag retaining wall 9 during installation, allowing the mortar-made stone slag retaining wall 9 to work stably for a long time.

[0036] The drainage pipe 11 and the filter layer 12 in this example are both horizontally evenly spaced. The filter layer 12 is higher than the bottom of the protective net 5 connected to the mortar-made stone slag retaining wall 9. The above-mentioned structural design can discharge the rainwater accumulated in the mortar-made stone slag retaining wall 9 and prevent the soil from being discharged along with the rainwater.

[0037] Working principle: During construction, a layer of soft soil on the surface of the original soil layer 1 is first stripped off and piled up in a temporary soil covering place to be used as planting soil 4 and top soil 14. Then, the surface of the original soil layer 1 is compacted, and the construction slag 2 generated during construction is covered on the surface of the original soil layer 1, and the surface of the construction slag 2 is compacted to Figure 1 As shown in the stepped shape, the inclined part is sprinkled with planting soil 4, and the platform drainage ditch 6 is set in the horizontal part, and Figure 2 As shown in the figure, side drainage ditches 7 are set on both sides of the planting covering soil 4 and the platform drainage ditch 6, and the surface of the planting covering soil 4 is covered with a protective net 5 and grass and shrub seeds are sown for greening. Then, a mortar-stone slag retaining wall 9 is installed at the bottom of the compacted slope 3, and a platform at the top of the compacted slope 3 is installed as shown in the figure. Figure 1 As shown, a top drainage ditch 13, a top covering soil 14 and a mortar-laid stone drainage ditch 15 are sequentially arranged;

[0038] When it rains, the top drainage ditch 13 and the mortar-stone drainage ditch 15 guide and drain away most of the rainwater falling on the top covering soil 14, preventing the top rainwater from flowing onto the planting covering soil 4. The rainwater falling on the slope to form surface runoff is intercepted and collected by the platform drainage ditch 6 arranged at intervals during the downward flow, preventing the surface runoff formed by the rainwater from gathering on the planting covering soil 4 and continuously flowing away the planting covering soil 4. The intercepted rainwater enters the side drainage ditch 7 and flows downward in a concentrated manner.

[0039] The rainwater collected at the mortar-laid stone slag retaining wall 9 at the bottom of the compacted slope 3 is discharged through the drainage pipe 11 to avoid accumulation. The filter layer 12 installed at the end of the drainage pipe 11 can prevent the discharge of a small amount of soil carried in the rainwater, thereby preventing soil loss.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
