Description

Technical Field

[0001] The utility model relates to the technical field of sand prevention and blocking, in particular to a sand barrier for preventing and blocking sand on a road of a wind farm in a desert area. Background Art

[0002] In recent years, large-scale wind power projects in desert areas have developed rapidly. However, the raging sandstorms have brought many inconveniences to the construction and subsequent operation and maintenance of wind farms, especially the roads in the plant area. According to statistics, most wind farms located in desert areas have their maintenance roads buried by sand to varying degrees after one to two years of operation and maintenance, which in turn affects the smooth progress of operation and maintenance. At present, the most commonly used sand barriers in the engineering field in my country are flat sand barriers or vertical sand barriers. Flat sand barriers are to lay grass grids or stone grids on the sand surface on both sides of the road and plant drought-resistant plants in them, but a large area needs to be laid to be effective; vertical sand barriers are vertical steel pipes buried on both sides of the road, and iron mesh is installed between the steel pipes. After years of weathering, they still need to be manually recovered. The above-mentioned sand barriers not only consume a lot of manpower and material resources, but also increase the cost of the project, which puts a lot of pressure on the budget of wind farm roads. Utility Model Content

[0003] The utility model aims to provide a sand barrier for preventing and blocking sand on wind farm roads in desert areas, thereby solving the above-mentioned problems existing in the prior art.

It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0023] Embodiment 1

[0024] like Figures 1 to 5 As shown, in this embodiment, a sand barrier for preventing and blocking sand for a road 4 in a wind farm in a desert area is provided, comprising a triangular column array 1 parallel to the road 4, a flat sand barrier 2 and drought-resistant plants 3; a plurality of triangular column arrays 1 in a triangular shape are arranged adjacent to each other in sequence along the length direction on both sides of the road 4, and the triangular column array 1 comprises a plurality of staggered triangular prisms 8; a near-road side 6 of the flat sand barrier 2 extends between two adjacent triangular column arrays 1, and a far-road side 5 of the flat sand barrier 2 extends a distance away from the road 4; the drought-resistant plants 3 are arranged in the flat sand barrier 2.

[0025] The triangular column array 1, the flat sand barrier 2 and the drought-tolerant plants 3 are all arranged parallel to the road 4 on both sides of the road 4, and the length and width of the arrangement on the windward side are twice that on the leeward side. The triangular column arrays 1 are arranged along the length of the road 4, adjacent to each other, and the triangular prisms 8 at both ends of the first row of the near-road side 6 of the triangular column array 1 are connected to the triangular prisms 8 at the corresponding positions of the next triangular column array 1. The near-road side 6 of the flat sand barrier 2 is laid flat on the sand surface 7 between two adjacent triangular column arrays 1, and extends outward from the last row of triangular prisms 8 on the far-road side 5 of the triangular column array 1 for 10 to 20 meters. The drought-tolerant plants 3 are planted in the flat sand barrier 2 to form a plant barrier.

[0026] In this embodiment, the triangular column array 1 includes multiple rows of triangular prisms 8 arranged parallel to the road 4, and the number of triangular prisms 8 in each row gradually decreases from the near road side 6 to the far road side 5, until there is only one triangular prism 8 on the far road side 5 of the triangular column array 1; two adjacent rows of triangular prisms 8 are arranged alternately; when the triangular prisms 8 are arranged, the top angle side 9 faces the wind and the back side 10 faces the road 4. The flat sand barrier 2 is composed of multiple adjacent prismatic grids 12, and the drought-resistant plants 3 are arranged in the prismatic grids 12.

[0027] The flat sand barrier 2 is the first to come into contact with the wind and sand. The plant barrier can block part of the wind and sand and reduce the wind speed at the same time. After the remaining wind and sand enters the triangular column array 1, the triangular prism 8 on the far road side 5 is the first to block the wind and sand. The triangular prism 8 separates the wind and sand with two inclined surfaces and blocks part of the sand. The separated wind and sand enters the penultimate row of triangular prisms 8 on the far road side 5, and continues to separate the wind and sand and block part of the sand, and so on, until the first row of triangular prisms 8 on the near road side 6, which has the effect of blocking wind and sand.

[0028] In this embodiment, each row of triangular prisms 8 is arranged at different heights. When arranged row by row from the near road side 6 to the far road side 5 at a certain distance, the height of the triangular prisms 8 exposed from the sand surface 7 decreases row by row, and the entire triangular prism array 1 is in the shape of a triangular slope when viewed from above. The higher the height of the triangular prisms 8 exposed from the sand surface 7, the deeper the buried depth.

[0029] In this embodiment, a row of the triangular prism array 1 on the near road side 6 includes 6 to 9 triangular prisms 8; the specific number can be selected according to actual conditions.

[0030] In this embodiment, the height of the triangular prism 8 is 0.8 to 3 m; the height of the part of the triangular prism 8 exposed from the sand surface 7 is 0.3 to 1.5 m; the triangle of the bottom surface 11 of the triangular prism 8 is 0.3 to 0.6 m long and 0.1 to 0.3 m high; the relevant data can be selected according to actual conditions.

[0032] In this embodiment, the side length of the prismatic grid 12 is 0.8-1.2 m, the thickness is 0.1-0.2 m, and the height is 0.1-0.2 m; the relevant data can be selected according to actual conditions.

[0033] In this embodiment, the prismatic grids 12 and the triangular prisms 8 are both prefabricated from red mud-based polymer materials.

[0034] In this embodiment, the drought-tolerant plants 3 include Nitraria tangutorum, Hippophae rhamnoides, and Haloxylon ammodendron.

[0036] In this embodiment, the triangular column array 1 is composed of 28 prefabricated triangular prisms 88 of different lengths, the bottom surface 11 of the triangular prism 8 is 0.4m long and 0.15m high. First, 7 triangular prisms 8 are arranged parallel to the road 4 from the near road side 66, with a spacing of 0.5m between each prism, which is the first row; then 6 are arranged 0.5m away from the first row towards the far road side 5, each of which is arranged at the interval of the previous row of triangular prisms 8, which is the second row; thereafter, the left and right spacing of each row of triangular prisms 8 and the front and rear spacing of each row are 0.5m, and the number of triangular prisms 8 in each row decreases by one row until the last row has one triangular prism 8; the top angle side 9 of the triangular prism 8 faces the wind, and the back side 10 of the triangular prism 8 faces the road. The number of triangular prisms 8 in each row, the height of the sand surface 7 part and the buried depth are shown in the following table:

[0037]

[0038] The prismatic grid 12 of the flat sand barrier 2 has a side length of 1m, a thickness and a height of 0.1m, and is laid flat on the open space between the triangular column arrays 1, with a burial depth of 0.1m. No flat sand barrier 2 is set in the triangular column array 1. The flat sand barrier 2 is made of a plurality of prefabricated red mud-based polymer prismatic grids 12, which are laid flat on the sand surface 7 between each triangular column array 1, and start from the last row of triangular prisms 8 on the far road side 5 of the triangular column array 1, and extend outward by 10m. At the same time, Haloxylon ammodendron is planted in each prismatic grid 12 to form a plant barrier.

[0039] The triangular column array 1, the flat sand barrier 2 and the drought-resistant plants 3 are combined to form a sand barrier for preventing sand and consolidating sand on the road 4 of a wind farm in a desert area.
