The baskets arc tilled on site ~.+~itti <br />clean-hard stones. <br />b) The selvedges of the gabions are the thicker perimeter and edge <br />wires to which the wire mesh is securely tied to withstand sudden <br />or gradual stress from any clircction. <br />c) Reinforcing wires are the thicker wires incorporated into the <br />netting during fabrication. <br />• d) The diaphragms are internal wire mesh partitions which di.v.i.de <br />the gabion into eyual-sized cells. <br />e) Lacing or binding wire is the wire used to assemble and join <br />the gabion units. <br />f) Connecting wires are the internal.cair.es used to prevent the <br />gabions from bulging. <br />FABRICATION <br />Galvanized Steel Clire Mesh Gabions. Gabions sha.l.l be Fabricated in <br />such a manner that the sides, ends, lid, and diaphrayms can be <br />assembled at the construction site into rectangular basE:ets of the <br />sizes specified and shown on the dra~:~ings. Gabions shall be of single <br />unit construction; the base, lid, ends, and sides stlall be either <br />woven into a single unit or one edge of. these manbers connected to <br />the base section of the gabion in such a manner that strength and <br />fle::ibility at the connecting point is at ].east equal to that of <br />the mesh. there the length of the gabion c::cceds oni: raid one-half <br />its horizontal width, the gabion shall be equally divided by diaphragms <br />of the same oaesh a!id gauge as the body of the gabions, into cells <br />• whose length does not exceed the horizontal. width. 'I'lie gabion shall <br />be Furnished with the necessary diaphragms secured in proper position <br />on the base in such ~ manner that nu additional Lying i.s rcq~iircd at <br />this juncture. <br />-4- <br />
