to construction of the gabion wall. Foundation soil shall meet the minimum bearing
requirement of 2,000 psf.
5) ASSEMBLY AND PLACEMENT
The assembly and placement of gabions shall be in accordance with the following
procedures:
Assembly. Rotate the gabion panels into position and join the vertical edges with fasteners
for gabion assembly. Where lacing wire is used, wrap the wire with alternating single and
double half hitches at intervals between four (4) to five (5) inches. Where spiral fasteners
are used trim the ends to secure the spirals in lace. Where ring alternate fasteners
P P P 9 type
are used for basket assembly, install the fasteners at a maximum spacing of 6 inches. Use
the same fastening procedures to install interior diaphragms where they are required.
Interior diaphragms will be required where any inside dimension exceeds three (3) feet for
gabion baskets thicker than 12". Diaphragms will be installed to assure that no open
intervals are present that exceeds three (3) feet. For baskets 12" or less rectangular cells
are allowed with dimensions 36" in one direction and not to exceed 72" in the perpendicular
direction.
Placement. Piece the empty gabion on the foundation and interconnect the adjacent
gabions along the top, bottom, and vertical edges using lacing wire or spirals. Wrap the
wire with alternatingsingle and double half hitches at intervals between four 4 to six 6
9 O ( )
inches. Spiral fasteners are commonly used for the assembly and interconnection of
welded mesh gabions. Spirals are screwed down at the connecting edges then each end
of the spiral is crimped to secure it in place. Lacing may be used as needed to supplement
the interconnection of welded mesh gabions, and the closing of lids.
Interconnect each layer of gabions to the underlying layer of gabions along the front, back,
and sides. Stagger the vertical joints between the gabions of adjacent rows and layers b
99 J 9 I ce Y y
at least one-half of a cell length.
5) FILLING OPERATION
After adjacent empty wire gabion units are set to line and grade and common sides properly
connected, they shall be placed in straight-line tension to gain a uniform alignment. Staking
of the gabions may be done to maintain the established proper alignment prior to the
placement of rock. No temporary stakes shall be placed through geotextile material.
Connecting lacing wire and other fasteners (as allowed) shall be attached during the filling
operation to preserve the strength and shape of the structure.
Internal connecting cross -tile wires shall be placed in each unrestrained gabion cell greater
than 18 inches in height, including gabion cells left temporarily unrestrained. Two internal
connecting wires shall be placed concurrently with rock placement, at each 12-inch interval
of depth.
In welded mesh gabions these crossties or stiffeners will be placed across the corners of
the gabions (at 12 inches from the corners) providing diagonal bracing. Lacing wire or
preformed wire stiffeners may be used.
The gabions shall be careful) filled with rock b hand methods ensuring alignment, g y y u g g ment,
avoidingbulges, and providing a compact mass that minimizes voids. At no point in the
a
9e P 9 P
filling process may rock be mechanically placed from a height of over 36" from machine to
fill area. Machine placement will require supplementing with handwork to ensure the desired
P q PP 9
results. The cells in any row shall be filled in stages so that the depth of rock placed in any
one cell does not exceed the depth of rock in any adjoining cell by more than 12 inches.
Along the exposed faces, the outer layer of stone shall be carefully placed and arranged by
hand to ensure a neat, compact placement with a uniform appearance.
The last layer of rock shall be uniformly leveled to the top edges of the gabions. Lids shall
be placed over the rock filling using only approved lid closing tools as necessary. The use
of crowbars or other single point leverage bars for lid closing is prohibited due to the
potential for damage to the baskets.
The gabion lid shall then be secured to the sides, ends, and diaphragms with spiral
binders approved alternate fasteners or lacing wire wrapped with alternating single and
PP 9 Pp 9 9
double half-hitches in the mesh openings.
Any damage to the wire or coatings during assembly, placement and filling shall be
repaired promptly in accordance with the manufacturer's recommendations or replaced
with undamaged gabion baskets.
