[0057] Please refer to Figure 1-Figure 5 , the present embodiment provides a road sand protection system 100 suitable for quicksand areas, which includes a sand-blocking fence group 110 , a sand-fixing grid group 120 and a grass grid group 130 .

[0058] Further, the sand blocking fence group 110 is arranged on both sides of the road 150 along the extending direction of the road 150 .

[0059] In the quicksand area, there are often many sand dunes on both sides of Highway 150. The sand barrier group 110 includes a first sand barrier group 114 and a second sand barrier group 115 . Wherein, the first sand-blocking fence group 114 is located at the foot of the sand dunes on both sides of the road 150 ; the second sand-blocking fence group 115 is located at the top of the sand dunes on both sides of the road 150 .

[0060] Furthermore, the sand blocking fence group 110 is the outermost barrier of the entire road sand protection system 100 suitable for quicksand areas. The sand...

[0091] This embodiment provides a road sand protection system suitable for quicksand areas, which has the same basic structure as the road sand protection system for quicksand areas provided in the first embodiment, the difference is that this system is suitable for quick sand areas The road sand protection system also includes psammophytes. Among them, the psammophytes are planted in the sand piled up near the sand blocking fence and on the sand dunes.

[0092] Specifically, the sand-fixing grid group on the windward side of the dunes and the inter-dune area between the dunes are artificially planted with psammophytes, such as Artemisia orbiscus, etc. by sowing. On the grass grid on the leeward slope of the dune, artificially plant psammophytes, such as Artemisia annus, Amygrhiza sativa, etc., by sowing. Artificially plant sandy shrubs in the blank central position of the grass grid, such as: Haloxylon, poplar, caragana, flower sticks, Nitraria, japonica, red willow, etc. T...

[0098] This embodiment provides a method for constructing a road sand protection system suitable for quicksand areas, including:

[0099] On both sides of the road, set up sand-blocking fences, sand-fixing grid groups and grass grid groups;

[0100] Set up sand-blocking fences along the extension direction of the road, and set the sand-blocking fences at the foot and top of the sand dunes on both sides of the road;

[0101] Lay the sand-fixing grid set from the windward slope foot of the dune to the top of the dune slope;

[0102] Lay the grass grid group from the top of the leeward slope of the dune to the foot of the dune; and control the height of the sand-fixing grid group and the grass grid group to be lower than the height of the sand-blocking fence.

[0103] Specifically, in the protected area, from the windward side to the farthest from the road, gradually approaching the road, set up sand-blocking fence groups, sand-fixing grid groups, and grass grid groups in sequen...

Abstract

The invention relates to the field of sand storm prevention and control, in particular to a road sand storm protection system suitable for an area of shifting sand and a construction method of the road sand storm protection system. The system comprises sand stopping fence groups, a sand fixing gridding group and a grass square group. The sand stopping fence groups comprise a first sand stopping fence group and a second sand stopping fence group; the first sand stopping fence group is positioned at slope toes of sand dunes on two sides of a road; and the second sand stopping fence groups are positioned at tops of slopes of sand dunes on two sides of the road. The sand fixing gridding group is laid from windward sides of the sand dunes to the tops of the slopes of the sand dunes. The grass square group is laid to feet of the sand dunes from the tops of slopes of leeward sides of the sand dunes; and the heights of the sand fixing gridding group and the grass square group are smaller thanthe heights of the sand stopping fence groups. By arrangement of the high sand stopping fence groups, sand substances can be stopped from entering the system, the sand fixing gridding group and the grass square group are arranged on the sand dunes, the sand substances of the sand dunes can be fixed effectively, and then a road and a roadbed in the system can be protected effectively.

Description

technical field [0001] The invention relates to the field of sandstorm prevention and control, in particular to a road sandstorm protection system suitable for quicksand areas and a construction method thereof. Background technique [0002] The research on desert science in our country started from the wind and sand control project, which was also the social development demand at that time. It started with the sand control project on the Lanzhou-Yinchuan section of the Baolan Railway that crossed the Tengger Desert section six times. Before that, a series of Major sand control projects for railways and roads, such as more than ten desert railway lines such as Lanxin, Jier, and Ganwu, among which the construction and research results of the "five belts in one" railway sand control system were proposed for the Shapotou section of the Baolan Railway. The 50km-long section of the Dacaotan-Junkeng section of the Lanzhou-Xinjiang Line, which is seriously damaged by sand, has estab...
