Construction technology of gabion net

The popularization and application of gabion network structure has been gradually carried out in China. It is summarized that the structure has nine advantages. High strength. Deformation ability, good habit of foundation deformation. Flexible structure, not easy to crack. Durability and economy. It can effectively resist the impact of earthquake. Water permeability. The predetermined value of the supply roughness coefficient (m). Supply vegetation beautification; Natural landscape environment. The introduction of the theory of ecological environment can effectively reduce the impact on the environment.

As the technical process of the new structure, in order to meet the requirements of planning and construction, the construction specifications for gabion mattress and Gabion gabion are as follows: PVC aluminized zinc steel wire gabion mesh is made of low-carbon steel wire, and the surface is coated with plastic.

Bevel difference: >12mm mesh length and width tolerance: ± 35mm galvanizing amount: not less than 250g/m2 (specification gb/t183993). The gabion mesh adopts hot-dip galvanized low-carbon steel wire and twisted hexagonal steel wire mesh formed by machine weaving. The process is hot-dip aluminizing and zinc coating before weaving. Type lw90 × 90(±5mm)。 Mesh 90mm × 90mm(±3mm)。 The wire diameter of the mesh body is ￠ 2.6mm, and the edge wire diameter is ￠ 3.2mm

Mesh limit error: ± 5% 3. Gabion pad: used for various slope protection projects. With a thickness of 0.15~0.50m, it can be made into gabion pads of various specifications. Pad (2~3m in specification × 1m × 0.25m as an example) it is formed by connecting the grid body of the above grid data. Gabion steel wire is used for connecting materials. The cage body and the edge of the cage body are combined to form a whole structure.

Gabion: used for various retaining wall structures. The specification is 2~6m long, 1m wide and 0.5~1m high. Gabion pad: it is necessary to select solid stone with good weathering resistance and durability as filling material. (doghead stone, gravel and pebble are all acceptable) its block diameter is 10cm~20cm
