Description

Technical Field

[0001] This utility model relates to the field of mobile sand dune control technology. Specifically, it is a sand control structure that integrates sand barriers and biological measures. Background Technology

[0002] Mobile sand dunes move with the wind and have low surface vegetation cover. When managing mobile sand dunes, sand barriers are typically placed on the dune surface to prevent wind erosion and reduce dune mobility. Subsequently, grass seeds or saplings are planted on the dune surface at an appropriate time. However, because wind speeds and humidity vary across different parts of the dune, placing the same sand barriers everywhere, while achieving the same sand-fixing effect, will result in differences in efficiency and cost. Similarly, vegetation survival rates vary in different locations on the dune. Therefore, it is necessary to use different management methods at different locations on the dune through a well-designed approach to maximize the effectiveness of sand control. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to provide a sand control structure that combines sand barriers and biological measures to maximize the sand control effect and balance cost and efficiency by using different sand control methods for different locations of sand dunes.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sand control structure integrating sand barriers and biological measures, wherein strip sand barriers and grid sand barriers are set from 2 / 3 of the windward slope of a moving sand dune to the bottom of the slope. The strip sand barriers are arranged at the bottom of the slope, and the grid sand barriers are arranged on the slope surface and connected to the strip sand barriers. Cuttings are planted on the ground on the leeward side of the strip sand barriers, and grass seeds are sown in the ground on the leeward side of the grid of the grid sand barriers.

[0005] In the aforementioned integrated sand control structure combining sand barriers and biological measures, the extension direction of each of the strip sand barriers is perpendicular to or intersects with the wind direction, and adjacent strip sand barriers are arranged parallel to each other.

[0006] In the aforementioned integrated sand control structure combining sand barriers and biological measures, the top of the cutting is lower than the height of the strip sand barrier, and the distance between the cutting and the strip sand barrier is less than the length of the strip sand barrier above the ground.

[0007] In the aforementioned integrated sand control structure combining sand barriers and biological measures, a water-proof sleeve is fitted over the middle of the cutting, and a water-absorbing tube is installed between the water-proof sleeve and the cutting.

[0008] The above-mentioned sand control structure combining sand barriers and biological measures includes a moisture-guiding pipe installed inside the waterproof sleeve. The other end of the moisture-guiding pipe extends underground. Guide plates are staggered on the inner wall of the moisture-guiding pipe. The guide plates are inclined upwards. One edge of the guide plate is fixedly connected to the inner wall of the moisture-guiding pipe. The top end of the moisture-guiding pipe is inserted into the water-absorbing cylinder.

[0009] In the aforementioned integrated sand control structure combining sand barriers and biological measures, the bottom end of the waterproof sleeve is inserted into the ground, and the top end of the waterproof sleeve is level with or below the ground.

[0010] The aforementioned integrated sand control structure combining sand barriers and biological measures includes a grid sand barrier comprising two or more first strips and two or more second strips, wherein the first strips and the second strips are intersected and form multiple rectangular areas.

[0011] In the aforementioned integrated sand control structure combining sand barriers and biological measures, the extension directions of the first and second barriers both intersect with the wind direction, and one corner of the rectangle formed by the intersection of the first and second barriers is positioned facing the wind.

[0012] In the aforementioned integrated sand control structure combining sand barriers and biological measures, a mesh is provided along the length of the first and second barriers at their edges below the ground, and grass seeds are placed between the mesh and the first or second barrier.

[0013] In the aforementioned integrated sand control structure combining sand barriers and biological measures, the density of the cuttings gradually decreases from the bottom of the slope upwards.

[0014] The technical solution of this utility model has achieved the following beneficial technical effects:

[0015] By setting up strip sand barriers at the bottom of the slope, where the wind speed is low, the strip sand barriers can meet the needs of windbreak and sand fixation. At the same time, the strip sand barriers are low in cost, highly efficient in deployment, and the high humidity at the bottom of the slope ensures the survival rate of cuttings and facilitates the rapid formation of vegetation cover. By setting up grid sand barriers on the slope, the windbreak and sand fixation effect is maximized, and by sowing grass seeds, vegetation gradually forms on the slope, achieving comprehensive desertification control.

[0021] The integrated sand control structure combining sand barriers and biological measures in this embodiment, such as Figure 1 As shown, strip sand barriers 1 and grid sand barriers 2 are set up from 2 / 3 of the way up the windward slope of the mobile sand dune to the bottom of the slope. Strip sand barriers 1 are placed at the bottom of the slope, and grid sand barriers 2 are placed on the slope surface and connected to strip sand barriers 1. The length of strip sand barriers 1 on the sand dune is slightly shorter than the length of grid sand barriers 2. Since the wind speed on the slope is low, strip sand barriers 1 are sufficient to achieve the effect of windbreak and sand fixation. Strip sand barriers 1 have relatively low cost and high deployment efficiency. Each strip sand barrier 1 is set perpendicular to or intersects the wind direction, and adjacent strip sand barriers 1 are set parallel to each other to block wind and sand. The use of grid sand barriers 2 on the slope surface can maximize the effect of windbreak and sand fixation. In addition, no sand barriers are set at the top 1 / 3 of the windward slope, so that the wind force can be used to flatten the top of the sand dune and reduce the height of the sand dune. After the strip sand barrier 1 is set up, cuttings 3 are planted on the ground on the leeward side of the strip sand barrier 1. The density of the cuttings 3 gradually decreases from the bottom of the slope upwards. Grass seeds 6 are sown in the ground on the leeward side of the grid sand barrier 2. Specifically, a mesh 7 is set along the length of the edge of the grid sand barrier 2 below the ground. The mesh 7 is fixed to the bottom edge of the grid sand barrier 2 by sewing or other fixing methods. A channel is formed between the mesh 7 and the grid sand barrier 2. The channel contains grass seeds 6. After one end of the grid sand barrier 2 is pressed into the sand, sowing is carried out simultaneously.

[0022] The water content at the bottom of the sand dune slope is higher than that at the top and top. Using cuttings 3 at the bottom of the slope can ensure a high survival rate. At the same time, taking advantage of the rapid growth of cuttings 3, sand-fixing vegetation can be quickly formed at the bottom of the slope. Grass seeds 6 are used on the slope. After germination, grass seeds have strong vitality and better stability, gradually forming vegetation on the slope.

[0023] like Figure 3 As shown, the top of the cutting 3 is lower than the strip sand barrier 1, and the distance between the cutting 3 and the strip sand barrier 1 is less than the length of the strip sand barrier 1 above the ground. The strip sand barrier 1 is used to protect the cutting 3, reduce the damage of wind and sand to the cutting 3, and improve the survival rate of the cutting 3.

[0024] like Figure 3As shown, a water-proof sleeve 4 is fitted over the middle of the cutting 3. A water-absorbing cylinder 5 is installed between the water-proof sleeve 4 and the cutting 3. The bottom end of the water-proof sleeve 4 is inserted into the ground, and the top end of the water-proof sleeve 4 is flush with or below the ground. A waterproof membrane can be covered on the top end of the water-proof sleeve 4. The waterproof membrane is fixed around the water-proof sleeve 4. The middle of the waterproof membrane is concave to form an inward concave cone. The cutting 3 passes through the center of the inward concave cone and there is a gap between the two. A moisture-guiding tube 8 is installed inside the water-proof sleeve 4. The other end of the moisture-guiding tube 8 extends into the ground. Guide plates 9 are staggered on the inner wall of the moisture-guiding tube 8. The guide plates 9 are inclined upward. One edge of the guide plate 9 is fixedly connected to the inner wall of the moisture-guiding tube 8. The top end of the moisture-guiding tube 8 is inserted into the water-absorbing cylinder 5. By setting up the moisture-guiding pipe 8, the humid air underground can be guided upward to the water-absorbing cylinder 5. The water-absorbing cylinder 5 helps to evenly distribute the water, allowing the cuttings 3 to absorb more water. At the same time, the guide plate 9 is inclinedly connected to the inside of the moisture-guiding pipe 8, and the guide plate 9 and the inner wall of the moisture-guiding pipe 8 form a small water storage space. When the condensate on the wall of the moisture-guiding pipe 8 flows downward, or when rainwater or dew from the ground flows downward into the moisture-guiding pipe 8, the water is stored in the water storage space.

[0025] like Figure 2 As shown, the grid sand barrier 2 includes two or more first baffles 21 and two or more second baffles 22. The first baffles 21 and the second baffles 22 are intersected and form multiple rectangular areas. The extension directions of the first baffles 21 and the second baffles 22 are all intersecting the wind direction. One corner of the rectangle formed by the intersection of the first baffles 21 and the second baffles 22 is set to face the wind. By utilizing the windward angle, the wind force is dispersed, the wind direction forms a dispersed flow, the wind speed is greatly reduced, and the sand fixation effect is improved.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
