Cage cage
The gabion cage is divided into several cells by a partition board (double twisted hexagon metal mesh) with an interval of 1 meter. In order to strengthen the strength of the gabion cage structure, all the side ends of the face mesh plate are made of steel wire with a larger diameter. Control and guide rockfall protection of river, flood discharge dam and diversion dam to prevent water and soil erosion; protect the road protection of retaining wall of the coastal defense project of the soil retaining structure of the bridge.
Defining information
Net cage refers to the box type net cage made of heavy hexagonal net, so it is called "gabion net or gabion net cage". In Europe, it is also called gabion net or gabion net cage. The gabion cage is filled with stones at the construction site to form a structure with flexibility, water permeability and integrity, such as the erosion prevention works of retaining wall, river lining, weir and other supports.
Gabion net (gabion net) is a cage made of angular net (hexagonal net) woven by metal wire. The wire diameter used is different according to the size of hexagon. In case of hexagon of metal wire with metal coating, metal wire with wire diameter of 2.0mm to 4.0mm shall be used. In case of hexagon net woven by PVC coated metal wire, PVC (metal) wire with outer diameter of 3.0mm to 4.5mm shall be used. The wire at the edge of outer frame shall be one size thicker than that of hexagon net [1].
Characteristic
(1) Economy. Just put the stone into the cage and seal it.
(2) The construction is simple and does not need special technology.
(3) It has a strong ability to resist natural damage, corrosion and adverse weather.
(4) It can withstand large-scale deformation without collapse.
(5) The silt between the gaps of cage stones is conducive to plant production and can be melted into one with the surrounding natural environment.
(6) It has good permeability and can prevent damage caused by hydrostatics.
(7) Save transportation costs. It can be folded up for transportation and assembled on site.
(8) Environmental protection. Cadmium (CD) < 10ppm, lead (PB) < 50ppm, and other harmful substances such as mercury (Hg), hexavalent chromium (Cr6 +, PBB, PBDE) were not detected, which fully met the environmental protection standards of Rosh.
