Windbreak and construction method of windbreak

A construction method and technology of windbreak walls, applied in basic structure engineering, soil protection, construction, etc., can solve the problems of inability to measure the distribution of sand grains in the sand transition layer with height, the limitation of the application effect of windbreak structures, and the wind direction in windy sand areas Unstable changes and other problems, to achieve the effect of good wind and sand prevention, simple structure, and time-saving maintenance and repair

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

example 1

[0066] Example 1: In 2010, Xihetao, No. 2 Community, Xika Village, Liujiaguan Town, had a management area of ​​17.4 hectares, and the soil was sandy loam. Known by the locals as White Beach, the birthplace of wind and sand. After three years of surface wind protection, a total of more than 2,000 meters of wind protection walls have been set up. Now it is the production base of a large-scale pastoral crop - Huanggu Niang, with a listed output of more than 20,000 catties per hectare. many benefits.

example 2

[0067] Example 2: In 2015, the Lvhai Southwest Mountain in Linhai Town contracted a 25-square-meter sloping farmland through intensive management. After contracting, two windbreak walls with a length of more than 300 meters were erected in the upwind direction. Through such technical measures to check and balance, not only the crops were planted as scheduled, but also the conditions were quite good. Moreover, the sowing done by the mechanical operation of no-tillage technology, which others said was impossible, was used, and the local people were completely conquered.

example 3

[0068] Example 3: Heiniu Mountain, Liujiaguan Town, the implementation plot of intensive management in 2015, with an area of ​​25 hectares. This land has been cultivated in rotation for many years, and no one has grown "good crops". Even if the seedlings emerge, they will not be blown to the sky by the wind, but they will also be killed by the wind and sand. They can only belong to the paradise of wormwood. The violent and ravaging wind makes people have no "spectacle". Such geographical conditions have been governed by the Fengwang people, and the windbreak wall has made the raging wind bow down. Not only have good seedlings been obtained, but the harvest after autumn is also good. Let the nearby villagers are very recognized. After such governance, the original wind and sand have become as stable as roots.

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...
