Gabion Woven Wire Basket, SZ. 9' x 3' x 3' - Galvanized

Product Description:

Gabions are defined as double-twisted, hexagonal, woven galvanized steel wire mesh baskets with a rectangular box shape. Gabion baskets come in various sizes and dimensions. Gabions are used in civil engineering, road building, military applications and architectural decorations.

Gabion baskets are commonly used for various applications including, but not limited to, retaining walls, steep slopes, rock fall areas to trap sediment, mechanically stabilized soil retaining structures, stream bank protection, slope paving, outfall structures, weirs, drop structures, etc. The purpose of rock gabions is to prevent undercutting and/or scouring at the base of steep slopes. Vegetation may be incorporated into the gabion by placing cuttings between the gabion layers. The cuttings will take root in the gabions and the soil behind the structure. The vegetation provides additional stability once the root structure has developed.

The compartments or cells of the Gabion Baskets are of equal size and dimension and are formed by internal diaphragms being placed within the basket. The compartments or cells are filled with natural stone and the diaphragms minimize stone migration within the basket providing even distribution of the stone fill throughout the basket, even after structural movement. Gabion Baskets feature a rigid structure, durable life and greater strength for civil engineering construction, road building, military applications and architectural decorations.

The selvedges of the gabion baskets are the thicker perimeter and edge wires to which the wire mesh is secured as to withstand sudden or gradual stress from any direction. Reinforcing wires are the thicker wires incorporated into the netting during fabrication. The internal diaphragms are the internal wire mesh partitions which divide the gabions into cells. Lacing or tie wire is used to assemble and join the gabion units. Connecting wires are the internal wire used to prevent the gabions from bulging. Alternative wire fasteners are ASTM approved wire fasteners used in lieu of lacing.

Fabrication of Double Twisted Hexagonal Steel Wire Mesh Galvanized Gabions

Gabions are fabricated in such a manner that the sides, ends, lid and diaphragms can be assembled at the construction site into rectangular baskets of the sizes specified and shown in the drawing. Gabions are of a single unit construction, in which the base, lid, ends, and sides are either woven into a single unit or the edge of these members connect to the base section of the gabion in such a manner that strength and flexibility at the connecting point does not compromise the engineered structural design of the gabion. Where the length of the gabion exceeds one half its horizontal width, the gabion shall be divided by diaphragms of the same mesh and gauge as the body of the gabion, into cells whose length does not exceed the horizontal width. The gabion shall be furnished with the necessary diaphragms secured in proper position on the base in such a manner that no additional tying is required at this juncture.

Mesh Formation:

The double twisted hexagonal wire mesh shall have deformability sufficient to permit minimum of mesh elongation equivalent to 10% of the unstretched length of the mesh test section without reducing the gauge or the tensile strength of the individual wire strands to values less than those for similar wire, one gauge smaller in diameter.

Non-Raveling:

The double twisted hexagonal wire mesh is to be fabricated in such a manner as to be non-raveling. This is defined as the ability to resist pulling apart at any of the twists or connections forming the mesh when a single wire strand in a section of mesh is cut or broken.

Gabion Fill:

The stone fill material used for filling the gabion units shall be clean, hard stone with pieces ranging from 4 – 8 inches on the greatest dimensions. Stone filling shall not exceed 24-inch vertical drop above the gabion basket. All efforts shall be made to ensure that the stone fill material utilized in the design of the structure match the stone fill used in constructing the gabion structure.

Assembling and Placing:

a) Each gabion unit shall be assembled by tying or fastening all connecting seams. The binding wire shall be tightly looped around every other mesh opening along the seams in such a manner that single and double loops are alternated. An alternative wire fastener may be used in lieu of lacing wire. The alternative wire fasteners shall be applied at approximately 4” – 6” intervals on all vertical and horizontal seams. No less than 3 fasteners per one foot on any given seam.

b) A line of empty gabions shall be placed into position according to the contract binding wire or alternative wire fasteners shall be used to secure each unit to the adjoining one along the vertical reinforced edges and the top selvedges. An approved corner closure tool shall be used to adjoin adjacent gabions to insure a tight, neat seam and minimize gabion wired or fastened to the latter at front and back. The lid shall be secured with an approved closure tool to insure proper closure without excessive mesh deformation.

c) To achieve optimum alignment and finish for retaining walls, a minimum amount of stretching may be required.

d) Connecting wire shall be inserted during the filling operation as follows: The connecting wires shall be installed according to manufacturer’s instructions every 1’ vertical lift of the gabion unit.
