Gabion Unit Form: Box Gabions
BOX GABIONS MADE OF HOT –DIP GALVANIZED WIRE MESH is a popular type of box gabions in corrosion resisting bank works.
Standard cell sizes:
Dimensions (LXWXH) in meters
3 X 1 X 1
2 X 1 X 1
1,5 X 1 X 1
1 X 1 X 1
2 X 1 X 0,5
The standard type box gabion shall be made from flexible hot dip galvanized wire mesh.
Mesh Form: Twist Weave Wire Mesh
The mesh shall be hexagonal woven mesh of the type 8 X 10 cm with the Joins formed by twisting each pair of wires through three half turns.
The wire used in the fabrication of the gabions and in the wiring operation during, construction shall be in accordance with BS 1052:1980 “Mild steel wire” having an average tensile strength of 360-520 N/mm². These values refer to the wire before fabrication of the netting. The diameter of the wire used in the fabrication of the netting shall not be less than 2.7 mm.
All wires used in the fabrication of the gabions and in the wiring operation during construction shall be galvanized in accordance with CYS EN 10244 – 2:2009. The minimum zinc coating on wire 2.7 mm in diameter shall not be less than 245 gr/m². In case the diameter of the wire used in the fabrication of the netting is greater than the value specified, then the thickness of the zinc coating shall be in accordance with CYS EN 10244-2:2009.
The adhesion of the zinc coating to the wire shall be such that when the wire is wrapped six turns round on a cylindrical mandrel having four times the diameter of the wire it does not flake or crack when rubbing it with the bare fingers.
All edges of the standard gabions including end panels and the diaphragms shall be mechanically selvedged in such a way as to prevent reveling of the mesh and to develop the full strength of the mesh. The wire used for the selvedge shall have a diameter equal to or greater than 3.4 mm. The zinc coating of these wires shall be in accordance with CYS EN 10244-2:2009.
Sufficient lacing and connecting wire shall be supplied with the gabions for all the wiring operations to be carried out in the construction of the gabions work. The quantity of such wire is estimated to be about 5 per cent approx. of the gabion weight supplied. The diameter of the lacing wire shall be 2.2 mm and the minimum mass of zinc coating shall be as given CYS EN 10244 – 2:2009.
Tolerances on diameter of zinc coated round wire shall be as given in table 2 of BS1052:1980.
