Gabion mattress operation, the first is to use woven wire gabion mattress. Can also be coated with plating and PVC (polyvinyl chloride), PVC gabion revetment mattress and can be used as toe protection.
Stone Box (box-shaped stone cage)。 Stone cage net is fixed in place so that filling of the wire or wire-mesh polymer material production。 Wire cage is a wire or woven mesh welded structures。 Both structures can be plated, box woven wire coated with an additional PVC。 Woven mesh gabion gabion welding flexible than larger, so to adapt to subsidence and load performance is different, though filled stone materials carefully to ensure that the stone fill is very dense, but sometimes that rigid stone box relatively easy to fill, for non-standard shapes, such as the corner, or you can generate a large subsidence areas, when the woven wire or lattice structure of the polymer deformation, without loss of strength, preferring to use such a structure。
Within the gabion fill with wind of hard stones as filler, it is stone or gabion mattress box will not due to abrasion and quickly broken. Different types of stone with stone cage net have different characteristics. Polygonal blocks of stone to interlock with each other very well, with its stone-filled cage deformation. Thus, a large retaining wall in shear, it is more effective than a round stone, the other side, it is conducive to stone cage connection. The general size of the average packing mesh size of 1.5 times. Single stone mesh size no smaller than the standard (often used in woven gabion size (60mmX80mm ~ 100mmX120mm), generally not more than 200mm standard size. Away from the stone on the fill placed in the cage outside and inside the stone is Sometimes the smallest stone size may relax the requirements.
Mechanical filled faster and generally cheaper, but not as good control of hand-filled。 For the modification of the retaining wall, it should produce a better appearance, and the formation of dense structure。 Both methods, the packing must be completely filled gabion。 Filler must be well filled in order to minimize the gap, good contact between a single block of stone, as much as possible to fill in tight, stone cage to reduce the possibility of moving the stone。 Packing size within the normal range, the polygonal and circular stones can be installed in close, and the other can add some soil。
