Gabion Overview

Gabions are a structure with stones in the wired bag. The stability is so excellent that even if a certain part of it is cut off, the general structure is never demolished. Gabions are used for a revetment structure to reinforce sides such as enbankment.

Gabion Usages

• •Various revetment structures
• •Temporary walls
• •Gates
• •Benches
• •Walls
• •Interior points
• •Eco-friendly construction materials

Gabion features

◎ Gabions maximize the stability of an embankment by preventing local scour.

◎ Gabions are eco-friendly products that maintain the ecological continuity over enbankment or river areas

◎ Gabions are eco-friendly products that maintain the ecological continuity over enbankment or river areas.

◎ Gabions require less construction costs than other products.

◎ There are no limitations in construction depending on weather or climate conditions. Constructability is excellent since there is no need for mold construction, concrete forming or curing, etc.

Description on tying intervals and joint sections at the bottom and top

The step of connecting gabion mattresses to form a general plane layout is the most important step in the gabion mattress construction process with regard to mattress stability. If the connection between mattresses is faulty, the plate mattress system will lose its functional performance, and the mattress gabion is no longer viewed as one united plate structure.
The most important element in gabion mattress construction is to prevent scour by securing sufficient protective performance and flexibility to possible scour or deformative activities.
The intensity of connection between gabion mattresses needs to be at least the tensile strength per unit length of the used mesh in order to stabilize the united structure's performance. For appropriate connection between mattresses, various joint methods may be used. Basically, the flexibility and plate unity of mattresses need to be secured.

2Hexagonal Gabion Gabion Revetment Construction

Steel wire nets are made of hexagonal meshes with steel wires twisted three times (in general, it is called dual twisting) to prevent loosening. A gabion net is made of hexagonal meshes of steel wires. Gabion nets are cut at intervals of 1m or according to the drawing.
Edges, compartments, and corners of gabions are securely protected to prevent the wire net structure from loosening and to maintain the intensity. Steel wires used at the edges shall be thicker than those used for meshes.
Panels and compartments at a gabion's edge shall be connected to the upper and vertical wires. The last panel shall be connected at the edge of the gabion's ground panel in a way of dual twisting for mechanical steel wire nets.
Compartments are connected to the ground in a screw-shaped connection that goes through gaps of the ground net and compartment panel nets.

3Rectangular Gabion

Galvanized steel wires or stainless steel wires are crossed at right angles geometrically, and the connecting points are welded by means of electric resistance. The produced rectangular gabion is called a welded gabion.
