In landscape engineering , road slope , embankment dams and steep mountains green complex engineering and technical personnel has been a headache problem. Over the years, they have been exploring a process that meets the mountain, Beaching protection requirements, but also achieve the effect of greening the environment , but also economical and convenient . In recent years , this process began to emerge , it is the ecological gabions application process .
According to experts, the ecological gabion application process is a high-strength galvanized steel wire woven into different specifications rectangular cages , filling stone structure inside the cage. After this structure is applied to the slope protection, in the dual role of anthropogenic and natural factors, the gap between the stones continue to be filled with dirt . Plant seeds in the soil gradually rock between root, thrive , roots firmly fixed stones and soil. So that you can achieve on the slope protection and greening purposes, improve the ecological , soil and water effects are very significant.
Ecological gabion cages process has the advantage in four areas:
First, the construction is simple, eco gabion cages craft Just a stone into the cage seal , do not need special skills , do not need water and electricity .
Second, low-cost , eco gabion cages cost only 15 yuan per square meter .
Three is a good landscape and protective effect. Engineering measures and plant measures of ecological gabion cages process uses a combination of methods , can effectively prevent soil erosion, landscape quick, visual effects and more natural, more abundant.
Fourth, long life, the life processes of ecological gabion cages for decades , and generally do not repair. It is precisely because of this, Huangshi Yangtze River berm project , Taihu flood levee protection project , the Three Gorges sandouping revetment , adopted this process .
Projects using two more intuitive explanation .
First, Beijing Huairou Nianziwan river training works , they did not use any plant technical measures , either gabion cages into plant seeds grow naturally in the soil , resulting in the formation of a completely natural landscape. In Beijing Miaofengshan river regulation , they use technology in ecological gabion cages in two different river plant technical measures , some sprinkled with drought-tolerant grasses , the results of both sides of the river will not see less than two months gabion up , eyes are green. Another section is planting small shrubs, such as pepper and other crops for local farmers to increase the economic income .
Ecological processes gabion gabion key technologies that , because it is flexible structure , even in the face of land subsidence , avalanches , landslides , etc., can also be relying on their ability to resist deformation .
Gabion materials and weaving techniques very particular weave gabion wire is used in high-strength low carbon galvanized steel wire , coated with a plastic polymer to optimize the appearance of a resin mold , its anti- corrosion , wear resistance, anti-erosion , anti- breaking ability.
Its weaving method using twisted grid technology is the use of gabion machine twisted hexagonal mesh woven , twisted way tied together to form the wire mesh , even twelve wire breaks, the mesh also will not unravel , abnormal firm.
