Embodiment Construction

[0006] see figure 1 , the present embodiment is like this: at first according to the year-round wind direction of this area and topography setting fixed stake 1, plastic net adopts single flat wire three needle warp-lined weft all over chain net, plastic net is expanded and established net 2, one by one and fixed stake Fixedly connected, fixed cables 3 are arranged on the lower sides of the vertical net, and the fixed cables are fixedly connected to the fixed piles. The upper and lower sides of the vertical net are connected with the upper and lower fixed cables by plastic net buckles, and a liner cable 4 is diagonally pulled on each side of the plastic vertical net. The height of the plastic vertical net is 1.3 meters, the void ratio of the net is 35%, and the distance between each fixed pile is 5 meters.

Abstract

A method for preventing wind and sand by a plastic warp knitting high standing net is to set and fix piles according to the conventional wind direction and topography in its are characterizing in spreading the plastic warp knitted nets to standing nets to connect with the fixed piles one by one, fixed cables are set at the up and down edges of the net connected with the fixed piles, the up and down edges are fixedly connected with the cables, the voide rate of the net is 30%-45%.

Description

technical field [0001] The invention relates to a method for preventing wind and sand, in particular to a method for preventing wind and sand by using plastic warp knitted vertical nets. Background technique [0002] Land desertification affects a quarter of the world's land area and nearly one billion people in the world. The desertification area of ​​chieftains in my country is expanding at a rate of 2,460 kilometers per year, and the direct economic losses caused by desertification disasters in my country reach 54 billion yuan each year. A big confidant. It seriously affects the sustainable development of our country's economy and society. In order to prevent the continuous migration of desertification, vegetation method and mechanical method are mainly used for prevention and control. Desert vegetation is affected by many restrictive factors, and auxiliary methods are needed to restore vegetation; mechanical methods currently include building an...
