Inner Mongolia River Channel Management Project to use the most to the number of grid cage, that is, high corrosion resistance, high strength and ductility of low carbon steel wire or steel wire covered with PVC using mechanical braiding of the stone-loaded metal cage
Gebin network for river regulation in Inner Mongolia is mainly used for river flood control, flood control and flood control embankment, river canal drainage Gufang dam
Gebin cages can be roughly divided into two types: one is the Gebin cages with a height of 0.4-1m, which are mainly used to reinforce the banks of the river and increase the flood discharge of the river to prevent scour at the foot of the river foundation dike; The other is the gabion mat with a height of 0.15-0.3 meters, as long as it is used for river slope protection, dike protection, canal lining, riverbed bottom protection and siltation promotion
The diameters of low carbon steel wire used in Gabriel cage conforming to ASTM A 975 and EN 10223 standards vary according to engineering design requirements Generally between 2.0-4.0 mm, the tensile strength of steel wire is not less than 38kg/m2, the weight of metal coating is generally higher than 245g/m2, and the edge wire diameter of gabion mesh is generally larger than the mesh wire diameter The length of the twisted part of the double wire shall not be less than 50mm. To ensure that the metal coating and PVC coating of the twisted part of the steel wire are not damaged
The mesh structure of the grid cage is similar to the honeycomb, which accords with the mechanics principle. It is a huge block structure with the same property, and has the function of bearing tension and absorbing unknown pressure
Gabinrenault pad has strong resistance to natural disasters, bad weather, corrosion resistance, acid and alkali resistance, oxidation resistance and other characteristics. There will be certain gaps between the stones of Gabinrenault pad. On the one hand, these gaps play a role in infiltration. When the river hits the green waterfront pad, the river will flow to the surface along the gaps to help the river and surface water form a good cycle; On the other hand, some silt will accumulate in the crevices with the passage of time, which provides a good environment for the growth of vegetation. Green vegetation will grow on the surface of the embankment slope, which will make the river have certain ornamental value. At the same time, these vegetation will also be of great help to adjust the ecological balance, protect the natural environment and purify the river
Gebin cage protection technology can better realize the organic combination of engineering structure and ecological environment
