Gabion Quality Process:
Examined Wire
Before weaving mesh,all of wires must be tested.
1)Tensile tsting: 350-575 Newton /square millimeter, accordance with south africa SANS675:1997 Standard.
2) Extended Range: equal or greater than 10%,accordance with European EN 10223-3?test specimens are equal or greater than 25 centimeter.
3) zinc coating Standard: galvanized wire circles round central axis six rounds,repeating 4times. accordance with SANS675:1997 Standard No zinc deposit Chek wrinkle, shedding phenomenon.
4) Scalability:when Tesing,wire winds each other on a per-minute rate of 15, and then reverse direction to the same speed winding, galvanized coat and the wire will not be broken,accordance with SANS675:1997 Standard.
Gabions connected technology by tie wire. All of tie wire is also used heavy galvanized or stainless steel wire, with specialized tools (simple tools can be) operation. General tied wire’s diameter is three millimeters, It’s tensile strength is 156-178 kg/mm2
Galvanized Coated hexagonal wire mesh
All of the following tests must be prior to weaving Gabion mesh:
1) All of steel wire (contains manufacturing gabion mesh,tie wire ) tensile strength is greater than or equal to 515MPa.
2) elongation rate: tested sample is 30 centimeters long at least,and elongation rate is is greater than or equal to 12%
3) Galvanized wire dimension error and galvanization amount’s requirement is in the following table.

2) 200%?elongation rate is greater than or equal to 200%
Gabion mesh:
1) tensile strength is greater than or equal to 4213kN /m.
2) Anti-punching shearsis greater than or equal to 2316kN /m
3) Sliver connection strength is greater than or equal to 1715kN /m.

installation requirement
1) Place Gabion in the leveling ground and pressure-redundant creases.
2) Front-back face-plate panels, and floor clapboard legislation plays a certain position in a box shape.
3) adjacent mesh cage group from top to bottom 4 corner connect together; borders or broken line from top to bottom, each 25 cm Bangzha an interval, using fixed-wire spiral Twist to tighten the connection.
4) several pieces of space Gabion placed on the ground, connected together. Mesh Cage in a lower group, tied up the upper mesh cage group adjacent box at the edge of the bottom line must be below the surface of the mesh cage group borders binded together, fixed togther with screw wire
5) with the appropriate size of the stones filled Gebin network, must be uniform to a group of Gebin net pad of the grid, fill in stone.
6) stone can be filled with a high degree of filling, filling gaps with small gravel, should take appropriate measures Ramming is to ensure that Xiang Tinei the density of filler. Filled to the top of the stone above the appropriate Hudian. Bulk density of the stone must be filled equalingor greater than 1.70 T/M3.
7) bare filled with stone, the surface must build artificial barrier leveling, stone community should overlap each other.
8) mesh cover will be built down packs, and pull in place before the board sides and clapboard strands together.
maintenance and repair
Gabion of life depends on the quality of the grid,stone's durability and stability of the more long-term fill material.
Plastic galvanized review / Gore plated steel is unlike any retaining wall and general will not be subject to chemical erosion.
During the installation process or open the circumstances, review of the plastic may be due to external factors partial damage. Signs from the site and test data show that this damage is only partial, would not lead to the provisional grid with some of the integrity , Nor the collapse of a row. Steel mesh grid is not used for the design and structure of the overall design of the grid strength, partial damage will not affect the structural integrity.
Gabion is retaining structure in its own role under the weight of the installation. With this move, the density of the structure will gradually increase, but have not filled the space will be reduced. When Gebin on soft soil, you can install some more .
Gabion wall will allow vegetation growth and structure of vegetation can maintain the integrity and maintain the natural state
