Submerged stacked and secured brush weed bundles - are held between grids by tie wires with anchoring rods

摘要

The sunk fascines or bundles of brushwood are stacked in crossed layers to form a submerged stack in water. This stack is prepared relatively fast and secured together. The submerged stack is made by placing crossed fascines in layers on a grid on the support bank. The completed stack is covered with another grid and the support and covering grid are tied together by wires passed through fascine layers. A hollow needle (7) is inserted from above through the top wire grid (6) and the fascines (5) and through the lower grid. This hollow needle guides the tie wire (8) on whose lower end is tied a transverse short rod (9). The rod, held at its middle, forms an anchor on the stack underside and the tie wire is pulled tight for retention.
