[0057] Please refer to Figure 1-Figure 6 , this embodiment provides a highway sand protection system 100 suitable for Gobi windy areas, which includes a sand barrier fence 110 , an edge fence 120 , a sand-fixing grid group 130 and a slope protection structure 140 .

[0058] Further, the sand blocking fence 110 is arranged on both sides of the highway 150 along the extension direction of the highway 150 , and is parallel to the direction of the highway 150 . The sand-blocking fence 110 is the outermost barrier of the whole highway sand protection system 100 suitable for the Gobi windy area. The sand-blocking fence 110 can suppress wind and sand, reduce the wind energy entering the road wind-sand protection system 100 suitable for the Gobi windy area, and block sand materials at the same time, so that the sand materials are accumulated near the sand-blocking fence 110, thereby protecting the sand-fixing grid group 130 , road 150, roadbed and slope protection structure 140.

[0091] This embodiment provides a road sand protection system suitable for the Gobi windy area, which has the same basic structure as the road sand protection system for the Gobi windy area provided in the first embodiment. The highway sand protection system in the Gobi windy area also includes psammophytes. Wherein the psammophytes are planted in the sandy soil accumulated near the sand-blocking fence.

[0092] Optionally, the above-mentioned psammophytes are selected from Haloxylon.

[0093] Specifically, after sand accumulation near the sand-blocking fence and in the area of ​​the Shage Formation, 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 in the Gobi windy area will become better and better, and eventually the plants and sand ...

[0095] This embodiment provides a method for constructing a highway sand protection system suitable for Gobi windy areas, including:

[0096] On both sides of the road, set up sand-blocking fences along the extension direction of the road, and set up edge-sealing fences along the intersecting road extension direction, and set up sand-fixing grid groups so that they are located in the area enclosed by the edge-sealing fences, sand-blocking fences, and roads;

[0097] On both sides of the road, the slope protection structure is set up by spraying and curing chemical curing agent.

[0098] Specifically, first set up the sand-blocking fence at the front of the windward side from the outside to the inside in sequence; then set up the edge sealing and locking of the windward side; then install the sand-blocking fence at the front of the leeward side; Set up the sand-fixing grid group on the windward side; then set up the sand-fixing grid group on the leeward side; then set up the sa...

Abstract

The invention relates to the field of Gobi strong-wind area sandstorm protection, in particular to a highway sandstorm protection system suitable for a Gobi strong-wind area and a construction methodof the highway sandstorm protection system. The system comprises sand stop fences, edge sealing fences and sand stabilization check sets. The sand stop fences are arranged in the highway extending direction, the edge sealing fences are arranged in the direction intersecting with the highway extending direction, and multiple independent protection regions are defined by the edge sealing fences, thesand stop fences and a highway; the sand stabilization check sets are located in the protection regions; each protection region is internally provided with at least one sand stabilization check set;and the height of the sand stop fences and the height of the edge sealing fences are both larger than the height of the sand stabilization check sets. Plenty of sand matter is interrupted by the sandstop fences and the edge sealing fences, a sand source is controlled, the wind speed of the position near the highway is reduced, on the one hand, the sand stabilization check sets protect and fix theground surface near the highway, on the other hand, the sand stabilization check sets reduce the near-surface wind speed of the position near the highway, the sand matter entering the sand stabilization check sets cannot be blown up again, and therefore it is guaranteed that the sand matter cannot move to a roadbed of the highway.

Description

technical field [0001] The invention relates to the field of wind and sand protection in the Gobi windy area, in particular to a highway sand blowing protection system suitable for the Gobi windy area 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 a long time, the desert Gobi region has been typified by 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. Its main plant sand control is the main measure, and engineering sand control is the supplementary measure. With the in-depth development of the Belt and Road Initiative and the Northwest Development Strategy, more and more high-grade highways have begun to be constructed in the Gobi desert area, and there are more and more reports on sand damage on high-grade highways, esp...
