Abstract
A reinforced gabion comprising two adjacent walls with a common edge manufactured using a single sheet of double twisted metal mesh fabric formed from metal wires which have two different diameters respectively corresponding to the two walls. Preferably the metal mesh fabric has a mesh with at least one twisted side formed from at least two metal wires woven together in which each twisted side is aligned in the direction of the common edge between the two walls.
Claims8
A reinforced gabion having a box structure capable of containing inert material, comprising two adjacent walls with a common edge made using a single sheet of double twisted metal mesh fabric formed of metal wires whose diameters differ from each other in the two walls.
A process for manufacturing a double twisted metal mesh fabric for the manufacture of a reinforced gabion comprising the stages of:
- placing a plurality of metal wires comprising at least one first group of wires having a first diameter and a second group of wires having a second diameter alongside each other in a frame;
- and
- weaving together pairs of adjacent wires to form a single double twisted metal mesh fabric having at least a first portion formed of wires of a first diameter and at least a second portion formed of wires of a second diameter woven together.
A process for manufacturing a reinforced gabion having a box structure capable of containing inert material, the box structure comprising two adjacent walls with a common edge made using a single sheet of double twisted metal mesh fabric formed of metal wires whose diameters differ from each other in the two walls, comprising the stages of:

- placing a plurality of metal wires comprising at least one first group of wires having a first diameter and a second group of wires having a second diameter alongside each other in a frame,
- weaving together pairs of adjacent wires to form a single double twisted metal mesh fabric having at least a first portion formed of wires of a first diameter and at least a second portion formed of wires of a second diameter woven together,
- folding the single sheet of metal mesh fabric to form two adjacent walls of the reinforced gabion with a common edge formed respectively from metal wires having two different respective diameters, and
- forming the remaining walls of the box-structure reinforced gabion with double twisted metal mesh fabric.
