Gabion Mesh
The mesh shall be hexagonal woven mesh wherein the joints are formed by twisting each pair of wires through two full turns. The wire used is to be as specified in Specification.

The undisturbed size of the mesh shall be 100 mm by 120 mm (the shorter dimension being taken from centre to centre of the parallel twisted joins and the longer dimension, which is nominal, being between the ends of the coaxial twisted joins). The tightness of the twisted joins shall be such that a force of not less than 1.75 kN pulling on one wire is required to separate it from the other, provided each wire is prevented from turning and the wires and the applied force are all in the same plane.
The wire mesh shall have elasticity sufficient to permit elongation of the mesh equivalent to a minimum of 10% of the length of the section of mesh under test without reducing the diameter or tensile strength of individual wire strands to values less than those for a similar wire 0.3 mm smaller in diameter.

Selvedges
All edges of the gabions, diaphragms and end-panels, except as stated in Sub-clause 1.7 of this Specification, shall be selvedged with a wire of which the core diameter is 3.4mm. Where the selvedge is not woven integrally with the mesh but has to be fastened to the cut ends of the mesh, it shall be attached by binding the cut ends of the mesh about it so that a force of not less than 8.5 kN applied in the same plane as the mesh, at a point on the selvedge of a mesh sample of length one (1) metre is required to separate it from the mesh.

Diaphragms and End-Panels
The diaphragms and end-panels shall be selvedged on the top and vertical sides only. The end panels shall be attached by twisting the cut ends of the mesh wires at the bottom of the panel about the selvedge on the base of the gabions. Similarly, the diaphragms shall be attached by twisting the cut ends of the mesh to the twisted joins of the mesh of the gabions. In each case the force required to separate the panels from the base shall not be less than that required to break the mesh over the same length.

Binding and Connecting Wire
Sufficient binding and connecting wire shall be supplied with the gabions to perform all the wiring operations to be carried out in the construction of the gabion work. The diameter of wire shall be 2.20 millimetres.

Filling Material
Filling material shall consist of hard, durable stone of minimum dimension 100 millimetres and maximum dimension 250 millimetres and shall be tightly packed to give a minimum of voids. The top layer of material shall consist of selected smaller stone of not less than 100 millimetres minimum dimension.

Tolerances ( Wire Diamter, Gabions Dimensions)
A tolerance on the diameters of all wire of + 2½ per cent shall be permitted. The length of the gabions is subject to a tolerance of + 3 per cent and the width of gabions to a tolerance of + 25 millimetres. All other gabion dimensions are subject to a tolerance of + 3 per cent of the sizes stated in this Specification.

Building a Retaining Wall with Box Gabbions

Gabion Boxes for Revetment Infrastructure Project in Ghana of Africa

Description

GABION scope:

Gabion boxes 1 m x 1 m, 2 m x 1 m .

Gabion mattress, thickness 300mm

Stone for rip-rap shall consist of well shaped hard dense durable rock. At least 50% of the pieces shall have a volume greater than 0.03 m3 and not more than 5% shall have a volume of less than 0.01 m3.

The surfaces to receive rip-rap shall be neatly trimmed to line and level, and all loose material compacted. The perimeter of rip-rap areas shall be protected by means of rock filled trenches, walls or other structures as detailed on the Drawings, or directed by the Engineer. Rock fill for perimeter trenches shall be of the same quality and size as that used in the construction of the adjoining rip-rap, but voids shall be filled with smaller stone and the entire backfill compacted.

A filter bed consisting of one or more layers of permeable material shall be placed on the prepared surface to the specified thickness. Care shall be taken not to mix the various grades of filter material, nor to disturb material already placed. If required, a filter fabric of an approved quality and grade shall be placed on the prepared surface or over the filter bed, as specified.

The stones shall be laid with close joints from the bottom of the slope of embankment or existing ground upward, the larger of the stones being laid at the bottom. The surface shall be hand packed, carefully bedded and tightly wedged with suitable spalls to form an even surface. Alternatively the Engineer may direct that the stones arc dumped from above and that the rip-rap is roughly dressed to the dimensions shown on the Drawings or instructed by the Engineer.

Gabions

Gabions shall be galvanized steel-wire-mesh cages, of acknowledged and approved make, packed with rock and used for the construction of retaining walls, channel linings, revetments and other anti-erosion structures. They shall comply with the standard sizes given in Table below, and subdivided into cells by means of diaphragms.

Standard Dimensions for Gabion Boxes and Mattresses

  Length (m) Width (m) Depth (m) Diaphragm Spacing (m) Maximum Mesh Size (mm) Boxes 1.0, 2.0, 3.0 and 4.0 1.0 0.3, 0.5 and 1.0 1.0 100 Mattresses 6.0 2.0 0.2, 0.3, and 0.5 0.6 or 1.0 as specified 80

The cut edges of all mesh used in the construction of gabions shall be selvedged.

Wire used for gabions and for tying during construction shall be in accordance with BS , shall have a tensile strength of at least 380 kN/m2 and shall comply with Table 8.3. Galvanising shall be in accordance with BS EN and shall withstand 220 hours of exposure to salt spray test before failure by rusting.

Wire mesh shall comply with BS EN and the maximum mesh size, measured across the twisted wire flats shall be as indicated in Table 8.3

Gabions of PVC coated mesh and binding wire shall be of an acknowledged make, subject to approval by the Engineer.

Gabions shall be constructed to the shapes and dimensions indicated on the Drawings, Special Specification or as directed by the Engineer.

The surface upon which gabions are to be laid shall be trimmed to line and level and compacted to a minimum dry density of 93% MDD (GHA SI). Where required, a foundation trench shall be excavated along the toe of the revetment or wall, to the dimensions indicated on the Drawings or specified.

The assembly and installation of gabions shall be in accordance with the manufacturer's instructions, subject to the Engineer's approval. Joints shall be stitched together with 600 mm minimum lengths of binder wire, with at least one stitch per 50 mm, and each end of the wire shall be fixed with at least two turns upon itself. Adjacent gabions shall be stitched together with binder wire along all touching edges.

Sufficient connecting wires shall be tensioned between the vertical sides of all the outer visible cells, to prevent the deformation of cages as they are filled with stone. The corners of gabion cages shall be securely tied together to provide a uniform surface, and ensure that the structure does not resemble a series of blocks or panels.

Gabion boxes shall be laid with broken bond throughout to avoid continuous joints both horizontally and vertically.

The alignment of the gabion wall structure shall be correct to within a tolerance of 100 mm of the specified alignment and the level of any course of gabion shall be correct to within a tolerance of 50 mm of the specified level. In addition adjacent gabions shall not vary by more than 25 mm in line and/or level from each other.

Gabion structures, as constructed shall be within a tolerance of ± 5% on the specified height or width and ± 3% on the specified length.

Gabions shall be handpacked with clean, hard, durable, unweathered boulders or broken rock of 150 mm minimum dimensions and 300 mm maximum dimension. The sides shall be packed first in the form of a wall, using the largest pieces, with the majority placed as headers with broken joints to present a neat outside face. The interior of the gabion shall be hand packed with smaller pieces and the top layers shall be finished off with larger pieces. The whole interior and top layers shall be packed tight and hammered into place.

A geotextile of approved quality and grade shall be placed behind gabion faces in contact with existing or backfilled ground. The Contractor shall ensure that the geotextile is not damaged during the construction or backfilling around the gabion works and any damaged or torn material shall be replaced.

At the back face and ends of completed gabion work, the existing soil shall be backfilled, thoroughly compacted against the sides of the gabions and finished flush with the top surface of the gabion.

Masonry for Structures

General

The length of any stone proposed for masonry shall not exceed three times its height. The breadth on the bed shall not be less than 150 mm nor greater than three quarters of the thickness of the wall.

All stratified stone possessing bedding planes shall be laid with its natural bedding plane as nearly as possible at right angles to the direction of load. In the case of arch rings, the natural bedding plane shall be radial.

Facework quoins shall be built to a height not exceeding 900 mm in advance of the main body of the work and adjacent walling stepped down on either side.

Masonry facework between the quoins shall then be built to a height not exceeding 450 mm above the backing, which shall then be brought up to level with the completed facework. At no time shall the backing be built higher than the facework.

Joints
Except for dry rubble walling, all joints shall be sufficiently thick to prevent stone-to-stone contact and shall be completely filled with mortar. Mortar shall be of the type described in the Contract and shall comply with the relevant requirements.

Protection of new work
Newly laid masonry shall be protected against the harmful effects of weather. All visible masonry and any surface below the masonry which will be visible on completion of the works shall be clean and free of damage.

Squared rubble-coursed or broken-coursed
All stones shall be truly squared and dressed on the beds and joints for a distance of at least 125 mm from the exposed face. Bond stones shall be provided at the rate of one to every 0.85 m2 of exposed face, and shall measure not less than 150 by 150 mm on the face, and not less than 450 mm in length or the full thickness of the wall if the latter is less than 450 mm. Sneck stones shall not be less than 75 mm in any dimension.
