Abstract

A sand control method using warp-webbing grid net is provided, which comprises preparing a warp-knitted net from plastic monofilaments and fixing piles in desert. The method is characterized in that the upper end of the fixed pile has an opening, each warp-knitted net is embedded vertically in the opening to form a vertical net, the vertical nets are conducted in Z-shaped arrangement (90 DEG angle), all the fixed piles are shared by two adjacent warp-knitted nets except the boarder piles, and the adjacent warp-knitted nets are combined to form a meshed sand barrier. The warp-knitted net is made of weather-resistant modified polyethylene monofilaments by warp flat lining and weft chain knitting, and has an air-permeability of 30-45percent and a height of 20-40 cm. The invention helps for sand control and has the advantages of reduced consumption of raw material, low processing cost, easy construction and maintenance, firm fixation, high strength of net, good wind-breaking and sand-fixing effect, and restore of natural growth of desert vegetation.

Description

A kind of warp-flat lattice-shape net sand damage prevention and cure method

Technical field

The present invention relates to a kind of method of defending and controlling sand, particularly a kind of utilization prevents and treats method through the sand damage of flat lattice-shape net.

Background technology

The living space of the Chinese nation in the desertification serious threat, is seriously restricting continuous development of society economy.There are 889 counties, flag, the differentiations in 30 provinces to be furnished with 173.97 ten thousand square kilometres of desertification lands in the whole nation, account for 18.12% of area, at present also cause the sandstorm in areas such as NORTHWEST CHINA and Beijing-Tianjin to take place frequently, having a strong impact on the production and the life of China's 400,000,000 populations.Defending and controlling sand is a complicated system engineering, on measures for sand prevention, is based on biological control measure, and engineering measure and biological control measure organically combine, and be multi-pronged, comprehensive regulation desertification.Present engineering measure mainly is to build sand-proof wall, or buries into sand-protecting barrier with reed, straw, careless class, though sand-fixing effect is arranged, it is big to build the sand-proof wall engineering quantity, the plant volume is big, transportation difficulty, resource-constrained, and perishable, it is big to bury the maintenance engineering amount underground, can't large-area applications promote.

Summary of the invention

Technical problem to be solved by this invention provides a kind of warp-flat lattice-shape net sand damage prevention and cure method, and this method can be fixed the sand by choke, promotes the dust storm deposition, can progressively recover the self-sow of desert vegetation again.

The inventive method is such: adopt plastic monofilament through netting, at ground, desert spud pile, it is characterized in that the spud pile upper end open, open height is with highly suitable through netting, insert sand ground to opening part, press 80-150 centimetre of square distribution of 80-150 cm x according to the stream intensity of this area, every embeds the spud pile opening part through netting and sets up net, come the inflection row to extend by an angle of 90 degrees, outside flash trimming is capable, all spud piles are shared through netting by adjacent two, and adjacent just forms many grid-like sand-protecting barriers through netting, and the spud pile open top end is fastening.Described through netting be by the weather-proof modification PEF of height monofilament constitute through flat inlaid thread chaining structure, the dictyosome rate 30-45% that lets in air, the high 20-40 of dictyosome centimetre.

Carry out the sand damage control by this method, can effectively increase the roughness on the face of land, desert, upset air stream, weaken wind speed, force stream to form concavo-convex stable deposition, sleet and wild plant seed are retained, form the desert skinning cortex, promote the growth recovery progressively naturally of desert vegetation.

By this method the trellis sand-protecting barrier is set, owing to adopted monolayer plastic through netting, raw material and processing charges are saved, the easy standard of construction maintenance, and fixation, dictyosome intensity height can repeatedly reclaim usefulness again, and use cost is lower relatively, and the sand damage prevention effect is remarkable.

The specific embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, the embodiment of the invention is such: adopt bamboo wood or plastics to make high 50-70 centimetre stake 1, open a high 26-41 centimetre in the upper end of stake, can be for the opening 3 of two layers of dictyosomes embedding, at ground, desert spud pile, press 80-150 centimetre of square distribution of 80-150 cm x according to the stream intensity of this area, stake is inserted sand ground to opening part, every embeds the spud pile opening part through netting 2 and sets up net, come the inflection row to extend by an angle of 90 degrees, outside flash trimming is capable, all spud piles are shared through netting by adjacent two, and adjacent just forms many grid-like sand-protecting barriers through netting, and the spud pile open top end is fixing again with iron wire or pile protection.The described employing through flat inlaid thread chaining structure braiding by the weather-proof modification PEF of height monofilament through netting forms, the dictyosome rate 30-45% that lets in air, the high 20-40 of dictyosome centimetre.

Claims

1. warp-flat lattice-shape net sand damage prevention and cure method, adopt plastic monofilament through netting, at ground, desert spud pile, it is characterized in that the spud pile upper end open, open height is with highly suitable through netting, insert sand ground to opening part, press 80-150 centimetre of square distribution of 80-150 cm x according to the stream intensity of this area, every embeds the spud pile opening part through netting and sets up net, comes the inflection row to extend by an angle of 90 degrees, outside flash trimming is capable, all spud piles are shared through netting by adjacent two, adjacent just forms many grid-like sand-protecting barriers through netting, the dictyosome rate 30-45% that lets in air, the high 20-40 of dictyosome centimetre.
