Specifications
Triple Twisted Hexagonal Mesh Gabion Mattresses are mostly used in projects of Flood
Embankment and intake works. Gabions types are boxes and mattresses. Aerct supplies
quality gabions system for flood protection, with detailed requirements for the
gabion wire, mesh fabric, filter fabric, stones and construction of gabions work as
following.
Technical Requirements of Gabion Mattresses:
Wire Fabric for Gabions
All wire used in the fabrication of gabions (including selvage wire and lacing wire)
and in the wiring operating during construction (including tie wire) shall be
annealed mild steel wire, having an average strength of 38-50 kg/mm2.
The adhesion of the zinc coating to the wire should be such that, when the wire is
wrapped six turns round a mandrel of 4 times the diameter of the wire, it does not
flake or crack to such an extent that any flakes of zinc can be removed by rubbing
with the bare fingers.
Wire mesh fabric shall be hexagonal triple twist mesh. The tightness of the twisted
joints shall be such that a force of not less than 1.7kN is required to pull on one
wire to separate it from the other wire provided that each wire is prevented from
turning and the whole process is done in one plane. Ultimate failure load in the
direction of the weave will be about 43 kN/metre length. Longitudinal elongation of
mesh will not exceed 10%.
The gabion mesh shall be cut, folded and wired together to form joints, angles,
curves or slopes which are not possible to obtain in the structures with the
standard rectangular gabions, the mesh must be cleanly cut, and the surplus mesh cut
completely out, or folded back or on to, and neatly wired to an adjacent gabion
face. The cut edges of the mesh shall be securely laced together with binding wire.
Gabions and mattresses should be laid on a filter fabric.
The filter fabric shall be of a non-woven melted fabric consisting of a mixture of
polypropylene and polythene or other similar materials. The fabric shall be
resistant to ultra violet rays and sunlight.
Where overlapping of fabric is required, the overlap shall not be less than 500 mm
and shall be sewn with a lock type stitch in such a manner that it produce a joint
as durable as the fabric.
The grade of fabric shall weigh not less than 350 gr/m2 and have a thickness of 0.5
mm.
Tensile strength shall be not less than 2kN/m. Permeability (ViH50) shall be not
less than 60l/s*m2.
Storage and handling of the fabric in no case shall be the geotextile be exposed to
direct sunlight, ultra violet rays, temperature greater than 60o C, mud, dirt, dust
and debris, to the extent that its strength, toughness or permeability
characteristics are diminished.
