Embodiment 1

[0008] Referring to Figure 1, the location of the fixed piles is selected according to the wind direction and terrain of the desert area. The fixed piles 2 are arranged according to the direction of the M-shaped obtuse angle of 150 degrees and extend in a wave shape. Pile, the upper and lower ends of the fixed pile are respectively provided with fixed cables 3 and 4 to connect adjacent fixed piles, the plastic net 1 is unfolded to form a net to connect the fixed piles, the upper and lower sides are connected to the upper and lower fixed cables, and the plastic mesh is made of high weather resistance modified polyethylene monofilament It is woven according to the three-needle warp-interleaved and weft-knitted chain structure. The plastic warp-knitted net is 1.5 meters high and the ventilation rate of the net is 45%.

Embodiment 2

[0010] Referring to Figure 2, the location of the fixed piles is selected according to the wind direction and terrain of the desert area. The fixed piles 2 are arranged according to the direction of the M-shaped obtuse angle of 120 degrees and extend in a wave shape. Pile, the upper and lower ends of the fixed pile are respectively provided with fixed cables 3 and 4 to connect adjacent fixed piles, the plastic net 1 is unfolded to form a net to connect the fixed piles, the upper and lower sides are connected to the upper and lower fixed cables, and the plastic mesh is made of high weather resistance modified polyethylene monofilament It is woven according to the three-needle warp-interleaved and weft-knitted chain structure. The plastic warp-knitted net is 1.2 meters high, and the ventilation rate of the net body is 30%. Set another plastic warp knitted net in the same direction at a distance of about 10 meters from the M-shaped plastic warp knitted net, and the corresponding s...

Abstract

The wind blocking and sand fixing method with M-type warp knitted plastic net includes: fixing piles in the places determined based on the wind direction and landform of the desert, connecting the upper and lower ends of adjacent piles with ropes, and spreading warp knitted plastic net and fixing with the piles and ropes. The warp knitted plastic net is in the height of 1.2-1.5 m and wind penetrating rate of 25-50 %. The present invention can block wind, fix sand and promote desert plant growth, and the knitted plastic net has long service life and relatively low cost.

Description

technical field [0001] The invention relates to a method for preventing and controlling sand, in particular to a method for preventing wind and desert with a plastic vertical net. Background technique [0002] my country is one of the countries with the most serious land desertification hazards in the world. There are 1.74 million square kilometers of desertified land in the country, accounting for 18.1% of the country's land area. The annual economic loss due to land desertification is more than 50 billion yuan, affecting nearly 400 million people. production and life. In order to prevent and control desertification, vegetation and mechanical methods are currently used to prevent and control sand. Desert vegetation is affected by many environmental factors, and auxiliary methods must be used to gradually restore desert vegetation. At present, the auxiliary methods mainly include building anti-sand walls and using wooden boards. , reeds, grass squares...
