Bottle Unit Item No. MAK-012
The Bottle Unit／ROCK BAG（NET GABION） is a double-layer raschel net structure bag material made by polyester fibers. It can be used with filling materials such as boulders, gravels, rubbles and concrete lumps that can be sourced at site. The bag has the soft adequate shape to follow changes in the river bottom, which is required for the revetment foundation consolidation work, and also the ability to fit into gaps, which is required for space filling work.
According to the amounts of filling materials, selection can be made from four types of bags containing 1, 2, 3 and 4t.

Characteristics
●During installation, the mouth closing part (knot part) does not protrude, so that when installed in rivers the bag shape will not easily become caught up by flotsam.
●The bags have outstanding weather resistance, chemical resistance, resistance to cold and heat, and shock resistance.
●Due to the double structure net and the 25mm mesh spacing, even if ruptures occur in a number of locations, the structure will prevent the filling materials from escaping.
●Because mechanical installation is mainly used both in the filling work and in the placement work, it will be possible to shorten the construction period.
●By using underwater lifting jigs, underwater installation will also be simple.
