Gabions

 

The modern Yuanxi gabion is a rectangular woven wire mesh box. Its strength lies in its double twisted hexagonal mesh of steel wire which is reinforced by selvedges of heavier wire running along the edges and by transverse diaphragms.
The protective coating is typically either:

  • heavily zinc galvanised wire
  • as above PLUS heavy duty PVC coating
  • galmac (galfan) coated with a 95%Zinc + 5% Aluminium Mischmetal Alloy
  • as above PLUS heavy duty PVC coating

Galmac (or Galfan) wire units offer enhanced durability, and are available upon request. This coating type is the most durable wire coating available internationally and is being increasingly used within Australia to ensure gabion structures achieve a longer design life (2 to 3 times more durable than zinc coatings of the same mass), thereby significantly reducing the life-cycle cost of the structure.
Yuanxi Gabions have significant advantages as retaining wall structures, including C

  • Permeability of the front face, ensuring drainage of backfill and no hydrostatic pressures behind the wall
  • Flexibility, ensures the woven mesh gabions accommodate different setlements unlike rigid systems eg. welded mesh cages
  • Ease of construction
  • One of the most economical retaining systems on the market
  • Incorporation as required of vegetation throughout the structure
  • Versatility, as the structure can be formed with a vertical, battered or stepped front face as required.

Yuanxi also provide additional tools and services to assist in the design and installation of Yuanxi Gabion structures, including C
Design support

  • Free preliminary design assistance or review (including free design software, drawings, etc) to ensure the design of the structure is the most appropriate and cost-effective solution to your problem
  • Provision of product and installation specification to assist in the tender preparation process
  • Free training seminars or presentations held at your offices
  • Free software for design or support, including an Architectural CD designed specifically for landscape architects or other professionals working with the built environment.

Gabions Installation support

  • Pneumatic lacing tools and high-strength lacing rings, which dramatically reduce the labour time and effort required in installing the gabion units
  • Gabion closing tools to assist in the installation process
  • Specialist non-standard sizes to ensure supply costs are reduced for a specific gabion structure, on-site installation training for major projects for either installers or site supervisors (including quality checklists)
  • Tensioning tools to assist in achieving a high quality finish in the installed structure
  • Preformed braces to assist with achieving a high standard

Heavy hexagonal mesh, also called big type hexagonal mesh. This mesh enjoys wide application. Heavy type hexagonal wire mesh can be made into gabion box which can used in control and guide of water or flood, flood bank or guiding bank, proventing of rock breaking, water and soil protection, bridge protection, strengthening structure of soil, protection engineering of seaside area, seaport engineering, isolation walls, protection of road, etc.
Galvanized Hexagonal Wire Mesh Heavy Type: Made with high quality low-carbon steel wire to weave, steel wire tensile strength is 38kg/M2. The wire diameter may reach 2.0mm-4.0mm. The steel wire is usually galvanized. And the galvanizing layer thickness can be made according to the customers request. Max. galvanizing quantity can be 300g/ M2.
PVC Coated Hexagonal Wire Mesh Heavy Type: PVC coated hexagonal Mesh is made of pvc coated wire that offers longer service life and better anticorrosion property.

Gabions Disadvantages/Problems:
Gabions are sometimes criticized as being unsightly. They can be made more attractive by use of attractive facing stone toward the front of the wall and by establishing vegetation in the spaces between the rocks.
• Low habitat value.
Gabions are more expensive than either vegetated slopes or riprap.
• The wire baskets used for gabions may be subject to heavy wear and tear due to wire abrasion by bedload movement in streams with high velocity flow.
• Difficult to install, requiring large equipment.

Gabions Maintenance:
Gabion should be inspected on a regular basis and after every large storm event.
• All temporary and permanent erosion and sediment control practices shall be maintained and repaired as needed to assure continued performance of their intended function.
• All maintenance and repair shall be conducted in accordance with an approved manual.
