The gabion net is made of low-carbon steel wire with high corrosion resistance, high strength, and ductility, or steel wire coated with PVC, which is mechanically woven. The box structure made from this net is called a gabion net box. According to ASTM and EN standards, the diameter of low-carbon steel wire used varies according to engineering design requirements. Generally between 2.0-4.0mm, the tensile strength of the gabion mesh steel wire is not less than 38kg/m2, the weight of the metal coating is generally higher than 245g/m2, and the diameter of the edge line of the gabion mesh is generally larger than the diameter of the mesh line. The length of the double stranded part shall not be less than 50mm to ensure that the metal coating and PVC coating of the stranded steel wire are not damaged.
The ecological stone cage net cage technology has four advantages:
One is that the construction is simple, and the ecological stone cage net cage process only requires sealing the stones into the cage, without the need for special technology or water and electricity.
Secondly, the cost is low, with ecological gabion cages costing only 15 yuan per square meter.
Thirdly, the landscape and protection effects are good. The combination of engineering measures and plant measures adopted in the ecological stone cage net cage technology can effectively prevent soil erosion, resulting in faster and more natural landscape effects.
Fourthly, it has a long service life. The ecological stone cage cage technology has a lifespan of several decades and generally does not require maintenance. It is precisely because of this that this process has been adopted in the dike protection project of the Huangshi section of the Yangtze River, the the Taihu Lake Lake flood control dike protection project, and the Three Gorges Sanduping revetment project.
Application of gabion box
Stone cage net can be used for slope support, foundation pit support, mountain rock surface hanging net spraying, slope vegetation (greening), railway and highway isolation and blocking net. It can also be made into box cages and mesh pads, used for anti erosion protection of rivers, embankments, and seawalls, as well as net cages for reservoir and river interception. The most serious disaster in rivers is the erosion of the riverbank by water flow, which causes flooding, resulting in significant loss of life and property, as well as significant soil erosion. Therefore, when dealing with the above problems, the application of this ecological grid structure becomes one of the good solutions, which can provide long-term protection for the riverbed and riverbank.
● Control and guide rivers and floods
The most serious disaster of a river is the erosion of its banks by water flow, which leads to flooding, causing significant loss of life and property, as well as significant soil erosion. Therefore, when dealing with the above problems, the application of the ecological grid structure has become one of the good solutions, which can provide long-term protection for the riverbed and riverbank.
● Channel Canal Bed
The construction of channels involves the stability of slopes and riverbed. Therefore, choosing an ecological grid structure has been the main method used in many natural river renovations and artificial channel excavations over the past century. It can effectively protect the riverbank or riverbed, and it also has the function of controlling water flow and preventing water loss, especially in environmental protection and water quality maintenance, which has good effects.
● Bank and slope protection
The application of ecological grid structure in river bank protection and slope toe protection is a very successful example, which fully utilizes the advantages of ecological grid and achieves ideal effects that cannot be achieved by other methods.
