The stone cage is a kind of iron wire or polymer screen pattern made of fixed stone filling. The wire cage is made of wire woven weaves or welded structures. These two kinds of structures can be plated, and the woven wire boxes can be coated with PVC. Using weathered solid stone as filler, it will not break quickly in the stone box or stone cage sinking. Cages with different types of blocks have different characteristics. The stone blocks with many corners can be well interlocked with each other, and the stone cages filled with them are not easy to deform. In landscape engineering, highway slope protection, embankment revetment and hill slope greening have always been a headache for engineers and technicians. Over the years, they have been exploring a technology that not only satisfies the protection needs of mountain and beach stability, but also achieves the effect of beautifying the environment, which is economical and fast. Gradually, this technology began to emerge, which is the application technology of ecological cage net. Ward Hardware Screen Products Factory of Anping County has developed into a comprehensive company which integrates production, processing and sale of stone cage mesh. Its stone cage mesh products are mainly used in embankment slope protection, retaining wall, bridge protection, River protection, highway subgrade protection, slope protection, ecological river bank slope regulation and other projects. . The application technology of ecological stone cage net is to weave high-strength galvanized steel wire into rectangular cages with different specifications and fill the cages with stones. After the structure is applied to the bank slope protection, the cracks between the rocks are filled with soil under the effect of artificial and natural factors. Plant seeds gradually rooted and germinated in the soil between the stones, growing vigorously, and roots firmly fixed the stones and soil. In this way, the intention of slope protection and landscaping can be completed, and the effect of improving ecology and insisting on Soil and water is also very obvious. Eco-cage cage technology has four advantages: first, the construction is concise, eco-cage cage technology only needs to put stones into the cage sealed, does not need special technology, also does not need water and electricity. Two, the cost is low, and the cost of the ecological cage is only 15 yuan per square meter. Three is the phenomenon and protection effect is good. The combination of the engineering method and the plant method selected by the ecological cage cage technology can effectively prevent soil erosion, and the phenomena are more natural and abundant. The four is to use life long and ecological cage technology for decades, and generally do not need to be repaired. It is precisely because of this that this technology is adopted in the Yellow Stone Section of the Yangtze River, the Taihu Lake flood control levee protection project and the Sandouping revetment project of the Three Gorges Project.
