Windbreak and construction method of windbreak

Abstract

The invention belongs to the technical field of wind and sand control, and discloses a windbreak and a construction method of the windbreak. Straw materials are made into small bundles of 10 centimeters thick and thin, straw roots are buried upwards to prevent from being bitten and torn by livestock, and the ideal windbreak effect is ensured; the buried height is 50-70 cm; or tree branch materialsare adopted, and the buried height being 70-100 cm is suitable; or wood pile sieving pieces are adopted, and the buried height is 1.1-1.3 m; according to the above functions, the wind speed can be slowed down or a wind direction can be forced to change, the degree of the surface damage caused by wind raging can be reduced, the maturation of the nutrient earth surface required by plants is facilitated, and it is ensured that the growth of the plants is facilitated; and a sandy land in which no grass or seedlings ever grow for many years is hopeful due to the fact that crops can be grown. According to the windbreak and the construction method of the windbreak, the sand control effect is remarkable due to the ingenious use of the windbreak; and the windbreak plays a positive role in ecological protection and agricultural production, and has been extensively imitated and applied.

Description

technical field [0001] The invention belongs to the technical field of wind and sand control, and in particular relates to a windbreak wall and a construction method. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] As early as the 90s of last century, there used to be three or four winds that filled the sky with yellow sand. After the wind passed, the original soil disappeared. In some places, deep pits and ditches were blown out, and people lived in places slightly leeward. Lots of "uninvited guests". Such an ecological environment not only affects the growth and harvest of crops, but also brings a lot of troubles to production and life. To change this situation, we have repeatedly tried the effect of windbreak and sand fixation for many years. [0004] The movement of sand particles in wind-blown sand flow includes creep, jump and suspension. Among them, creep is the movement form of sand particl...

AI Technical Summary

Problems solved by technology

[0007] In the prior art, the effect of windbreak and sand fixation is poor

[0008] The existing technology cannot measure the distribution law of the falling sand particles with height in the aeolian layer

[0009] However, due to the unstable change of wind direction in windy and sandy areas, the application effect of existing windproof structures is limited
