Protection engineering of seaside area
Stone Filled Gabion Box Advantage:
Flexibility: Flexibility is an important benefit of any gabion structure. The
double-twist hexagonal mesh construction permits it to tolerate
differential settlement without fracture. This property is
especially important when a structure is on unstable soil
conditions or in areas where scour from wave action or currents can
undermine the toe of the structure and cause structural settlement.
Durability: Gabions support plant growth which provides a live coating for the
wire mesh and stones, adding to their durability. Generally, the
wire mesh is needed for the first few years of the structure’s
life; later the void between the stones is filled with soil, silt,
and plant roots which act as a bonding agent for the stones.
Strength: Steel wire hexagonal mesh has strength and flexibility to
withstand forces generated by water and earth masses, and the
pervious nature of the gabion allows it to absorb and dissipate
much of that energy. This is evident on coast protection
installations where gabion structures remain effective long after a
massive rigid structure fails. Additionally, the double twisted
hexagonal mesh won’t unravel if cut.
Permeability: Gabion walls are previous to water and stabilize slopes by the
combined action of draining
and retaining, precluding the development of hydrostatic pressure
behind the gabion wall. Drainage is accomplished by gravity, as
well as evaporation as the porous structure permits air circulation
through it. As plant growth develops within the structure, the
process of transpiration assists in removing moisture from the
backfill – a much more efficient system than weep holes in standard
masonry walls.
Low cost: Gabion systems are more economical than rigid or semi-rigid
structures for the following reasons:
• It requires little maintenance
• Its installations does not require skilled labor and stone fill
is available on site or from nearby quarries,
• It requires little or no foundation preparation, as the surface
needs to be only reasonably level and smooth.
• Gabions are porous, requiring no costly drainage provision
Ecology: Gabions is an environmentally sensitive solution to slope
stabilization. It has already been mentioned that stone fill is
done with natural stones making the gabions, naturally porous
allowing interaction between the land and the water table and also
persuades deposition of soil in the smaller voids between the stone
fill during drainage that again promote vegetation growth.
Aesthetics: Gabions supporting vegetation has already been discussed; in some
case the vegetation growth is so intense, making the gabion
structure invisible, and pleasant to look at. Again if additional
effort is given during construction, the gabion can create really
pleasing structure with or without vegetation. Unlike other types
of materials such a modular block walls the gabion stones do not
discolor due to drainage.
Stone Filled Gabion Box Installation Process:
1. Ends,diaphragms,front and back panels are placed upright on the bottom section of wire mesh
2. Secure panels by screwing sprial binders through the mesh openings in adjacent panels
3. Stiffeners shall be placed across the corners, at 300mm from the corner. Providing a diagonal bracing,and crimped
4. Box gabion filled with graded stone by hand or with a shovel.
5. After filling,close the lid and secure with sprial binders at the diaphragms,ends,front and back.
6. When stacking tiers of the weled gabion,the lid of the lower tier may serve as base of the upper tier.Secure with sprial binders and add pre-formed stiffeners to exterior cells before filling with graded stones.
