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
The present invention relates to a kind of method of defending and controlling sand, particularly a kind of plastics found net wind blocking and sand desertification prevention method.
Background technology
China is one of the most serious country of desertification harm in the world, 1,740,000 square kilometres of the existing desertification lands in the whole nation, account for 18.1% of area, the economic loss that causes every year because of desertification reaches more than 500 hundred million yuan, influences the production and the life of nearly 400,000,000 populations.In order to prevent and treat desertification, mainly take vegetation and two kinds of methods of machinery to defend and control sand at present, desert vegetation is subjected to many such environmental effects, must there be householder method could progressively recover desert vegetation, householder method mainly contains and builds sand-proof wall at present, makes sand-protecting barrier with plank, reed, straw checkerboard barrier, nylon wire etc.The sand-proof wall construction is big; Reed, straw checkerboard barrier construction maintenance trouble, the life-span is short; Nylon wire cost height, mesh easily is offset; The wind prevention and sand resistance effect is all undesirable, and China's task of defending and controlling sand is very arduous.
Summary of the invention
Technical problem to be solved by this invention provides a kind of M plastic through netting wind blocking and sand desertification prevention method.This method constructing operation standard is simple, and cost is relatively low, and wind blocking and sand ends unconcerned effective.
This M plastic is such through netting wind blocking and sand desertification prevention method: wind direction and landform according to this desert area select to beat the spud pile position, it is characterized in that spud pile moves towards to be provided with for the 120-150 degree by M shape obtuse angle and undulate extends, about 5 meters interior settings of every section straight length of M shape are no less than three spud piles, the two ends up and down of spud pile respectively are provided with antilift wire and connect the adjacent fixed stake, plastic wire launches to set up net and is connected and fixed stake, both sides connect antilift wire up and down up and down, plastic wire is through flat inlaid thread chaining structure, net height 1.2-1.5 rice, the dictyosome rate 25-50% that lets in air.Use the inventive method, because the upright net undulate of plastics extends, it is long-pending to have increased the antiwind resistance Shamian Island, effectively stop multi-direction stream infringement, more effectively upset air stream, the energy of wind is reduced, the carrying amount descends, and forms two deceleration areas in M shape fence front and back, has more effectively blocked the desert reach.Use job specfication of the present invention convenient, long service life, relative cost is lower, the wind blocking and sand better effects if.

The specific embodiment
Embodiment one:
Referring to Fig. 1, wind direction and landform according to this desert area select to beat the spud pile position, spud pile 2 is that 150 degree move towards to be provided with and undulate extends by M shape obtuse angle, in about 5 meters of every section straight lengths of M shape three spud piles are set, the two ends up and down of spud pile respectively are provided with antilift wire 3,4 and connect the adjacent fixed stake, plastic wire 1 launches to set up net and is connected and fixed stake, both sides connect antilift wire up and down up and down, plastic wire is formed through flat inlaid thread chaining structure braiding by three pins by the weather-proof modification PEF of height monofilament, 1.5 meters of plastic warp net heights, the dictyosome rate 45% of letting in air.
Embodiment two:
Referring to Fig. 2, wind direction and landform according to this desert area select to beat the spud pile position, spud pile 2 is that 120 degree move towards to be provided with and undulate extends by M shape obtuse angle, in about 5 meters of every section straight lengths of M shape three spud piles are set, the two ends up and down of spud pile respectively are provided with antilift wire 3,4 and connect the adjacent fixed stake, plastic wire 1 launches to set up net and is connected and fixed stake, both sides connect antilift wire up and down up and down, plastic wire is formed through flat inlaid thread chaining structure braiding by three pins by the weather-proof modification PEF of height monofilament, 1.2 meters of plastic warp net heights, the dictyosome rate 30% of letting in air.At a distance of about 10 meters the plastic warp net of identical trend together is set through netting with this M plastic again, the straightway of two plastic warp net correspondences is parallel.
Claims (3)
1, the M plastic is through netting wind blocking and sand desertification prevention method, wind direction and landform according to this desert area select to beat the spud pile position, it is characterized in that spud pile (2) moves towards to be provided with for the 120-150 degree by M shape obtuse angle and undulate extends, about 5 meters interior settings of every section straight length of M shape are no less than three spud piles, the two ends up and down of spud pile respectively are provided with antilift wire (3,4) and connect the adjacent fixed stake, plastic wire (1) launches to set up net and is connected and fixed stake, both sides connect antilift wire up and down up and down, plastics net height 1.2-1.5 rice, the dictyosome rate 25-50% that lets in air.
2, M plastic according to claim 1 is through netting wind blocking and sand desertification prevention method, and its feature also is at a distance of about 10 meters the plastic warp net of identical trend together to be set through netting with this M plastic again, and the straightway of two plastic wire correspondences is parallel.
3, M plastic according to claim 1 is through netting wind blocking and sand desertification prevention method, and its feature is that also plastic wire is formed through flat inlaid thread chaining structure braiding by three pins by the weather-proof modification PEF of height monofilament.
