Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration, and in particular to a structure for ecological restoration of slopes of pumped-storage power stations in arid areas. Background Art

[0002] Slope ecological restoration structure is a comprehensive technical discipline that integrates geotechnical engineering, botany, soil science, fertilizer science, polymer chemistry, and environmental ecology. It is a protective structural system that combines traditional slope protection with ecological restoration. Due to the steep slope of high and steep rock slopes, it is impossible to use spray seeding to plant plants during the ecological restoration process. Therefore, during the ecological restoration process, planting holes are usually excavated in the rock wall of the slope and trees are planted in the planting holes. To resist erosion of the slope surface, reduce soil erosion, and achieve the purpose of protecting the environment, most artificial slope projects usually require slope surface protection. For example, laying blocks and planting vegetation in the blocks, using the combined effect of vegetation and slope protection blocks to reduce water erosion on the slope surface, thereby effectively preventing soil erosion and ensuring the ecological effect of the surrounding environment.

[0003] The bottom surface of the blocks currently in use contacts the slope. Although the bottom surface of the blocks has anti-slip grooves, they are still unstable under the impact of large water flows and are easily washed away by water, and cannot play a good role in slope protection.

[0004] After searching, the patent with the authorization announcement number CN115419086B discloses a vegetation slope protection and soil and water conservation device that is easy to assemble, including a retaining frame body and side plates. The retaining frame body includes a plurality of connecting bars, one side of the connecting bar is fixedly connected to a first positioning bar, the bottom of the connecting bar is fixedly connected to a second positioning bar, the top of the connecting bar is provided with a first positioning groove, one side of the connecting bar is provided with a second positioning groove, the first positioning bar and the second positioning bar of one connecting bar are respectively engaged with the first positioning groove and the second positioning groove of another connecting bar, one side of the connecting bar is fixedly connected to a connecting plate, one side of the connecting plate is provided with a through hole, one side of the connecting plate is provided with an inclined surface, and every four connecting plates are combined to form a through opening. The present invention can quickly install the vegetation slope protection and soil and water conservation device, and can reduce the accumulation of rainwater in the retaining frame body to avoid corrosion to the prepared slope protection and soil and water conservation device.

[0005] However, after the trees are planted, the soil needs to be watered to increase the survival rate of the plants. In arid areas, slope ecological restoration structures have poor water retention, making it difficult for the slope ecological restoration structure layer to firmly adhere to the slope surface, which is unfavorable for vegetation growth.

[0033] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0034] like Figure 1 As shown, the present invention provides a structure for ecological restoration of slopes of pumped-storage power stations in arid areas.

[0035] It includes a slope body 1, on which a holding device 2 distributed in a matrix is ​​provided; the holding device 2 includes an outer frame 3 and a plurality of holding frames 4 distributed in a matrix within the outer frame 3;

[0036] A plant planting hole 5 is provided in the middle of the retaining frame 4, and a water passage cavity 6 is provided inside the retaining frame 4. A water storage cavity 7 is provided on the side of the water passage cavity 6 close to the plant planting hole 5. Several infiltration tubes 8 are provided on the side wall of the water storage cavity 7 close to the plant planting hole 5. An opening is provided at the top of the water storage cavity 7 to connect the water storage cavity 7 with the water passage cavity 6; a water inlet hole 9 is provided at the top of the retaining frame 4, and the water inlet hole 9 is connected to the water passage cavity 6. A water outlet hole 10 is provided at the bottom of the retaining frame 4, and the water outlet hole 10 is connected to the water passage cavity 6.

[0037] The retaining frame 4 is arranged inside the outer frame 3, forming a solid and orderly structure. A plant planting hole 5 is provided in the middle part of each retaining frame 4, which makes it possible to green the slope. During rainfall, rainwater enters the water cavity 6 inside the retaining frame 4 from the water inlet hole 9, and flows into the water storage cavity 7 through the opening. When the rainwater in the water storage cavity 7 is full, the excess water overflows from the opening and flows into the water cavity 6, flows downward along the water cavity 6, and flows from the water outlet hole 10 into the water inlet hole 9 of the retaining frame 4 below. The rainwater continues to be injected into the water storage cavity 7 inside the retaining frame 4 below; the water in the water storage cavity 7 supplies moisture to the plant planting hole 5 through the infiltration tube 8, thereby ensuring that the plant soil has sufficient moisture in dry weather.

[0038] The top of the retainer 4 is provided with positioning strips 11 on either side of the water inlet 9, and the bottom of the retainer 4 is provided with positioning grooves 12 on either side of the water outlet 10, corresponding to the positioning strips 11. This facilitates the alignment of the upper and lower retainers 4, allowing the water outlet 10 to align with the water inlet 9, ensuring that rainwater from above can be drained from top to bottom, preventing rainwater from affecting the slope ecology.

[0039] The outer frame 3 is provided with through holes 13 at the top and bottom, corresponding to the water inlet 9 and the water outlet, respectively. Multiple retaining devices 2 are evenly distributed on the slope. Through the through holes 13 between the retaining devices 2, excess rainwater from the upper portion flows into the retaining devices 2 below, and then flows out of the slope from the lowest retaining device 2.

[0040] The retaining frame 4 is provided with a seepage hole 14, which connects the plant planting hole 5 with the water passage chamber 6. During rainfall, rainwater will fall into the plant planting hole 5. When the rain is too heavy and the soil is too wet, rainwater can flow from the seepage hole 14 into the water passage chamber 6 and then into the retaining frame 4 below. This not only prevents the soil from being washed away by the rainwater, but also ensures that the water storage chamber 7 in the retaining frame 4 below can store sufficient rainwater. To prevent soil from blocking the passage inside the retaining frame 4, a filter is provided at the entrance of the seepage hole 14 to prevent sand from entering the retaining frame 4.

[0041] In order to facilitate the installation between the retaining devices 2, a connecting rod 15 is provided between the retaining devices 2 of each row. The upper and lower ends of the connecting rod 15 are provided with a card slot 16. During installation, the outer frame 3 of the upper and lower retaining devices 2 is snapped into the card slot 16, which improves the installation efficiency. A water collection trough 17 is provided on the front of the connecting rod 15. Rainwater on the surface of the upper retaining device 2 flows downward along the surface of the retaining device 2 and falls into the water collection trough 17. Drain ports 18 connected to the card slot 16 are provided above and below the water collection trough 17. The drain ports 18 correspond to the through holes 13. The rainwater in the water collection trough 17 flows into the retaining device 2 below through the drain ports 18, and the rainwater overflowing from the upper retaining device 2 flows into the water collection trough 17 through the through holes 13 and the drain ports 18, and then flows into the retaining device 2 below through the drain ports 18, thereby preventing excessive rainwater from flowing into the plant planting holes 5.

[0042] In order to ensure that rainwater in the upper retaining device 2 can flow into the lower retaining device 2, the through hole 13 and the drain outlet 18 of the retaining device 2 need to be aligned. Therefore, a fixing hole 19 is provided on the front of the connecting rod 15, and a positioning hole 20 corresponding to the fixing hole 19 is provided on the retaining frame 4. An insertion rod 21 is inserted into the fixing hole 19 and the positioning hole 20. After the retaining device 2 is inserted into the slot 16, the retaining device 2 is moved to align the fixing hole 19 and the positioning hole 20, that is, the through hole 13 and the drain outlet 18 are also aligned, and then the retaining device 2 is fixed by inserting the rod through the fixing hole 19 and the positioning hole 20.

[0043] Among them, the upper and lower sides of the water collecting trough 17 are provided with upward inclined guide plates 22. The upper guide plate 22 can receive rainwater flowing down from the surface of the upper retaining device 2, and the received rainwater flows into the water collecting trough 17 through the drain outlet 23 set at the bottom of the guide plate 22. The inclined surface of the upper guide plate 22 can also expand the rainwater receiving area to ensure that sufficient rainwater falls into the water collecting trough 17, so that enough rainwater can be stored in the water storage chamber 7. The lower guide plate 22 can prevent rainwater from overflowing from the water collecting trough 17.

[0044] A water reservoir 24 is provided above the slope surface of the slope body 1 and is connected to the through hole 13 on the uppermost outer frame 3 via a water delivery pipe 25. When the water in the water storage chamber 7 is exhausted, the water in the water reservoir 24 is delivered to the through hole 13 on the outer frame 3 of the uppermost retaining device 2 via the water delivery pipe 25, replenishing the water storage chamber 7 from top to bottom.

[0045] The water reservoir 24 is buried within the slope body 1. Several drainage holes 26 are provided at the top of the water reservoir 24 along its length. A water retaining plate 27 is provided on one side of the drainage holes 26. Overflow holes 28 are provided on the sidewalls of the water reservoir 24. These overflow holes 28 are connected to the water delivery pipe 25 via an overflow pipe 29. When rainwater flows downward from the top of the slope, it is blocked by the water retaining plate 27 and flows from the drainage holes 26 into the water reservoir 24. Once the water reservoir 24 is full, the overflowing water is discharged from the overflow holes 28 through the overflow pipe 29 into the water delivery pipe 25. The overflowing water is then discharged through the water delivery pipe 25 into the water passage 6 within the retaining device 2, preventing a large amount of rainwater from the top of the slope from flowing into the slope and eroding the soil.

[0046] Working principle:

[0047] The retaining frames 4 are connected to each other through the cooperation of the positioning strips 11 and the positioning grooves 12, so that the water inlet hole 9 and the water outlet hole 10 are aligned, and then installed in the outer frame 3, so that the water inlet hole 9 and the water outlet hole 10 are aligned with the through hole 13 to form a retaining device 2, and then the retaining device 2 is connected and installed with other retaining devices 2 through the connecting rod 15. The through hole 13 of the topmost retaining device 2 is connected to the water reservoir 24 through a conveying pipe. When it rains, the water reservoir 24 will store rainwater. The rainwater on the surface of the retaining device 2 flows downward along the surface, flows into the water collection trough 17, and then flows into the water passage cavity 6 in the retaining frame 4 to replenish the water storage cavity 7. The water overflowing from the water storage cavity 7 flows through the water passage cavity 6 to the retaining frame 4 below, thereby pushing inward. When all the water storage cavities 7 are filled with water, the rainwater flows out from the through hole 13 of the bottom outer frame 3.

Those skilled in the art will appreciate that various modifications or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
