GABIONS – DEFINITION, ADVANTAGES, USES & EXAMPLES

a gabion There is a wire mesh box (Figure 1) filled with composite material – consistent with the size of the mesh mesh – serving as gravity Units forming the retaining structure.

It provides a means to contain aggregates of small and varied sizes that cannot be used to build masonry type gravity retaining walls. When such materials are put together and ‘contained’, they are made to perform their gravity role efficiently and economically.

Large Steel Wire Mesh Boxes (line drawing number 2), usually rectangular in shape, but variable in size, filled with low grade or waste stone – Financially sourced on site. Gabion units can be controlled as building blocks, To erect structures with unique flexible characteristics that enable them to be used curve And Desirous alignment. its underlying FLEXIBILITY There is an important feature that enables it to adapt itself to changes in size without any hassle. It will adapt to any Earth movement, and in the process of undergoing deformation, still remains structurally healthy. This is clearly a feature with distinct technical advantages over a conventional rigid or semi-rigid structure – particularly on sites where heavy settlements are anticipated.

The modern look of the gabion was developed by the Italian firm MACCAFERRI which is the world leader in this field.

The major characteristics of gabion structure can be cited as: Tolerance, FLEXIBILITY And vulnerability, With regard to durability, over the period of time when the trap begins to deteriorate, silt and vegetation combine with the rock filling to form a permanent structure that can remain intact even if the trap disappears completely. The internal feature of gabions has already been mentioned FLEXIBILITY Which enables it to adapt to any in-situ soil profile.

What sets Gabion apart from dry stone wall is that wire mesh is extremely strong under tension, the gabion structure can withstand stress to an extent that is quite impossible with dry stone wall. In this connection it should be emphasized that the wire mesh shell is not just a frame for holding stones; it works as reinforcement for the whole structure.

The high permeability of the gabion fill ensures automatic drainage, eliminating the need for measures such as the provision of weep holes.

Apart from everything else, gabion are enough Cheap Compared to their more traditional alternatives, both in terms of material and labor.

gabions are used

1) maintaining structures, from retaining walls, revetment and tow walls to embankments and cuttings,

2) anti-corrosion structures, such as sea walls, river banks, canal banks, dams, dams, streams and for protection of reservoirs and lakes.

Examples of gabion usage

Some of the uses of gabions are shown in the following figure.
