Application of screen nets

Mine sieving mesh in landscape engineering, highway slope, dike revetment and steep mountain green complex has been a headache for the engineering and technical personnel problems. Over the years, they have been exploring a process that can meet the requirements of the mountain, the stability of the beach, and can achieve the effect of green environment, but also economic and convenient. In recent years, this process began to surface, it is the application process of the ecological stone cage net.

According to the experts, the application process of the ecological stone cage net is made of high strength galvanized steel wire braided into different sizes of rectangular cages, cages filled with stone structure. After the structure is applied to slope protection, under the dual role of the natural and man-made factors, the gap between the stones continue to be filling soil. The soil seed gradually between the stones in the sprout, grow, root firmly fixed rocks and mud. So that the slope can achieve the purpose of protection and greening, improve the ecological, to maintain the effect of water and soil is also very significant.

The stone cage nets ecological process has four advantages. Is construction Jane griddle net, ecological gabion boxes process only needs the stone into cage sealing can be, do not need special technology, is not in need of hydroelectric power. The two is a low cost, ecological gabion boxes per square meter cost only 15 yuan. Three is the landscape and the protection effect is good. Combination of engineering and plant measures of ecological gabion boxes is used in the process, can effectively prevent soil erosion, quick effects of landscape, landscape effect is more natural, more abundant. The four is a long life, ecological stone cage nets process of life for decades, and generally do not repair. It is because of this, Huangshi Yangtze River dike dam project, Taihu Lake flood control embankment protection project, the Three Gorges Sandouping bank revetment projects use this technology.

The use of two engineering examples more intuitive description. One is in Beijing Huairou nianziwan channel regulation project in which they did not use the any plant technical measures, Ren infiltration stone cage cage in the soil to plant the seeds of natural growth, results in the formation of is completely natural landscape. In Beijing Miaofeng Shan Tao to govern, they in the two river ecological gabion boxes process using different measures of plant technology, a spread on the drought resistant grass seeds, on both sides of the river results less than two months can't see the stone cage net the eyeful are green. Another section is planting a small shrub, griddle net such as pepper and other economic crops, increase the income of the local farmers.

The key technology of the ecological stone cage is the stone cage net, because it is a flexible structure, even though the ground subsidence, collapse, landslide, and so on, can also rely on their own deformation ability to resist. The material and the knitting technique of the stone cage is very particular. The steel wire used in the woven wire mesh is a high strength low carbon steel wire. The surface is coated with plastic polymer. Its anti corrosion, wear resistance, erosion resistance, and anti fracture ability is very strong. The knitting method using twisted pair grid technology, stone cage net machine woven pairs twisted hexagonal network, twisted pair will wire tied together to form a network, even one or two broken wires, mesh will not unlock, abnormal firm.
