[0055] Please refer to Figure 1-Figure 6 , the present embodiment provides a highway sand protection system 100 suitable for sandbags passing through shrubs, which includes a sand-blocking fence 110, an edge-sealing fence 120, a sand-fixing grid group 130, and a slope protection structure 140.

[0056] Further, the sand blocking fence 110 is arranged on both sides of the road 150 along the extending direction of the road 150 . It is arranged on both sides of the highway 150 along the extension direction of the highway 150; the sand-blocking fence 110 includes multiple sections, and each section of the sand-blocking fence 110 is arranged between two adjacent shrub sandbags 151, and each section of the sand-blocking fence 110 is adjacent to each other. The two shrub sandbags 151 are V-shaped, and the V-shaped angle is 130°-150°. Further, on the windward side of the highway 150 , the top angle of each section of the sand-blocking fence 110 faces away from the road 150 , and on ...

[0094] This embodiment provides a road sand protection system suitable for crossing bush sandbags, which has the same basic structure as the road sand protection system for crossing bush sandbags provided in the first embodiment, except that the The road wind and sand protection system suitable for crossing sandbags in bushes also includes psammophytes. Wherein the psammophytes are planted in the sandy soil accumulated near the sand-blocking fence.

[0095] Optionally, the above-mentioned psammophytes are selected from Haloxylon.

[0096] Specifically, after the sand accumulation near the sand-blocking fence and the sand-fixing grid area, combined with biological sand control measures to plant psammophytes such as Haloxylon, and artificial watering and other measures to form biological sand control, as the plants grow, the applicable The comprehensive wind and sand protection effect of the road wind and sand protection system that passes through the sandbags in the shrub will...

[0098] This embodiment provides a method for constructing a road sand protection system suitable for passing through sandbags in shrubs, including:

[0099] On both sides of the road, after setting up sand-blocking fences along the road extension direction and edge-sealing fences along the intersecting road extension direction, set sand-fixing grids so that they are located in the protection area formed by the edge-sealing fence, sand-blocking fence and road enclosure ; Wherein, the sand-blocking fence includes multiple sections, and each section of the sand-blocking fence is set between two adjacent bush sandbags, and each section of the sand-blocking fence is V-shaped between two adjacent bush sandbags, V The included angle of the font is 130°-150°.

[0100] On both sides of the road, the slope protection structure is set up by spraying and curing chemical curing agent.

[0101] Specifically, first set up the sand-blocking fence at the front of the windward side from the ou...

Abstract

The invention relates to the field of gobi strong-wind area sand storm protection, in particular to a highway sand storm protection system suitable for crossing shrubbery sandbags and a construction method of the highway sand storm protection system. The system comprises sand stop fences, edge sealing fences and sand stabilization checks. Each sand stop fence comprises multiple sections, each sandstop fence section is arranged between two adjacent shrubbery sandbags in a V shape, and the edge sealing fences are arranged on the two sides of a highway in the direction intersecting with the highway extending direction; and the sand stabilization checks are located in regions defined by the edge sealing fences, the sand stop fences and the highway. Plenty of sand matter is interrupted by thesand stop fences, a sand source is controlled, the wind speed of the position close to the highway is reduced, the sand stabilization checks close to a roadbed of the highway protect and fix the ground surface near the highway and also reduce the near-surface wind speed of the position close to the highway, and through arrangement of the checks, the sand matter in the checks cannot move again, andtherefore it is guaranteed that the sand matter cannot move to the roadbed of the highway.

Description

technical field [0001] The invention relates to the field of protection against wind and sand in sandbag areas in shrubs, in particular to a sandstorm protection system for roads passing through sandbags in shrubs and a construction method thereof. Background technique [0002] Wind and sand disasters are one of the main factors affecting the construction and safe operation of railways and highways in the Gobi Desert. For traditional desert areas, desert areas have long been typified by the sand control of the Shapotou section of the Baolan Railway and the Tarim Petroleum Highway, and the effect of wind and sand control is also the most obvious. The main plant sand control is the main measure, and engineering sand control is the supplementary measure. More and more railways and roads are being built in the desert Gobi area, especially in the construction and modification of high-grade highways in recent years, and there are more and more reports on sand damage on high-grade...
