Embodiment Construction

[0015] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] In the embodiment of the present invention, such as figure 1 Shown is the original form of sand control, and produces local wind direction and sand dune direction, and also changes the local topography. The parallel high sand barrier in this design causes the sand dunes to form an included angle of 15° to 30° with the route; after the sand dunes form the included angle with the route, the sand dunes themselves have played the role of sand blocking. A large amount of aeolian sand was brought to bury the high sand barriers and grass squares, and there were flaky sand and tongue-shaped sand in some places, and even the aeolian sand hit the road. The embodiment of the present invention combines figure 1 And the situation that...

Abstract

The invention relates to the field of comprehensive wind-drift sand control and discloses a lap-joint slope wrapping wind prevention and sand fixation method. Control parameters of a sand accumulated road segment, including the dune moving direction, the dune size, the dune length, the size of an included angle between the dune and the route, the bury speed of wind-drift sand, and the frequency of wind, are measured and analyzed, and the sand accumulated road segment is subjected to lap-joint slope wrapping sand prevention treatment according to the control parameters. As the lap-joint slope wrapping sand prevention method is adopted, the durability of a sand prevention system is improved; and through scientific and reasonable selection of the position of a sand barrier, the utilization ratio of the sand barrier is improved, sand accumulation on roads is retarded, such adjunctive jobs as sand cleaning are reduced, and the desert road maintenance cost is lowered.

Description

technical field [0001] The invention relates to the field of comprehensive control of wind and sand, in particular to a method for windbreak and sand fixation of lapped slopes. Background technique [0002] At present, desert roads are mainly protected by using reeds. For routes mainly distributed in the oasis area, desert transition section (k226-k247), and desert hinterland (k247-k367), the protection forms are reed high-sand barrier type I and type II respectively. Type and Type III, the widths of grids on the left side are 15m, 60m, and 80m respectively, and the width of all grids on the right side is 40m. There are at least the following technical shortcomings in the sand barrier sand prevention method of the prior art: [0003] 1. The sand control works are basically arranged in parallel along the route, and the line type changes in a single way. [0004] 2. Part of the sand barrier is severely damaged by wind. [0005] 3. The sand barrier only reflects the characte...
