[0028] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0029] like Figures 1 to 6 As shown, the utility model provides a desert roadbed sand prevention system and emergency device, including a roadbed 1, and also including: two groups of high vertical sand barriers 2 arranged on one side of the roadbed 1 along the wind direction in sequence, the high vertical sand barrier 2 including a vertical pole 22 and a second sand net 21, the second sand net 21 is fixed between the two vertical poles 22, a plurality of emergency sand barriers 3 are installed between the high vertical sand barrier 2 and the roadbed 1, the emergency sand barrier 3 includes a first vertical plate 31 and a first inclined plate 32 obliquely arranged on the top of the first vertical plate 31, a first sand net 33 is installed between two adjacent first inclined plates 32, the first sand net 33 can block wind and sand while reducing the weight of the top of the first vertical plate 31 to prevent it from tipping over, and a grass grid 4 is installed between the emergency sand barrier 3 and the high vertical sand barrier 2.

[0030] By setting up two groups of high vertical sand barriers 2 with a height of 2m, two blocking barriers can be formed to block the wind and sand on the windward side of the roadbed 1. A small part of the wind and sand that passes over the high vertical sand barriers 2 is first blocked by the grass grids 4 to prevent the sand and dust from migrating to the roadbed 1. At the same time, a first vertical plate 31 and a first inclined plate 32 are set between the grass grids 4 and the roadbed 1. The first inclined plate 32 is inclined on the first vertical plate 31, which can block the wind and sand again while forming a backflow of the wind and sand and guiding it to the grass grids 4 again, so as to more efficiently block the wind and sand in front of the first vertical plate 31.

[0031] On the other side of the subgrade 1, there is a second vertical plate 5. At the top of the second vertical plate 5, there is a second inclined plate 51. The heights of both the second vertical plate 5 and the second inclined plate 51 are less than those of the first vertical plate 31 and the first inclined plate 32. Among them, part of the windblown sand that passes through or leaks above the high vertical sand barrier 2 crosses the subgrade 1 and forms a backflow on the other side, which is intercepted by the second vertical plate 5 and the second inclined plate 51 of the latter group that are lower than the first vertical plate 31 and the first inclined plate 32, preventing the accumulation of windblown sand on the other side of the subgrade 1. And a second inclined plate can be separately arranged on the other side of the second vertical plate to further block the windblown sand.

[0032] A clamping groove 34 is formed in the middle of the first inclined plate 32. At the top of the clamping groove 34, there is a clamping slot 35. A number of through holes 36 are formed in the first inclined plate 32. At the top of the first sand net 33, there is a clamping block 37. The clamping block 37 is in a cross shape and is used to be clamped in the cross hole formed by the clamping slot 35 and the clamping groove 34. On one side of the clamping block 37, there is a fixed plate 38, and through holes 36 are formed in the fixed plate 38.

[0033] When fixing between the first sand net 33 and the first inclined plate 32, the first sand net 33 can be directly tied or clamped and fixed between two first inclined plates 32, or by arranging a number of clamping blocks 37 on the first sand net 33 and forming a clamping slot 35 and a clamping groove 34 on the first inclined plate 32. When installing the first sand net 33, a number of clamping blocks 37 are directly clamped in the cross hole formed by the clamping slot 35 and the clamping groove 34, and then the clamping blocks 37 are fixed on the first inclined plate 32 by inserting bolts or inserting rods into the through holes 36 on the fixed plate 38 and the first inclined plate 32. At the same time, the first sand net 33 is fixed in the clamping groove in turn with bolts or inserting rods, improving the installation efficiency of the first sand net 33.

[0034] Reinforcing rods 39 are arranged at the inclined part between the first vertical plate 31 and the first inclined plate 32, which can prevent the bending between the first vertical plate 31 and the first inclined plate 32.

[0035] The included angle between the first vertical plate 31 and the first inclined plate 32 is 120° - 150°. The height of the first vertical plate 31 is 1 m, and the height of the second vertical plate 5 is 0.4 - 0.6 m, and the best height is 0.4 m.

[0036] When the included angle between the first vertical plate 31 and the first inclined plate 32 is set to 135°, the sand prevention effect is the best.

[0037] Based on the ideal embodiments of the present invention as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
