Figure 3. shows the location of
the ropes, posts, laborers and the inflating AquaDam®.
The number of ropes (lines) required by a particular sized AquaDam® is discussed
instable 2 and Figure 3. If ropes are to be used in the installation process,
they should be placed under the AquaDam® before water is added. The ropes are
attached to the base of the metal posts or trees, then run under the structure,
over the top, and back to the starting point. They should be held in a manner
that would allow the rope to be let out as the AquaDam® unrolls across the
stream. The rope should be twice as long as the AquaDam® when inflated, plus an
extra 50 feet.
Standing water or lake installations are much simpler than those using larger
AquaDams® or in live streams. The AquaDam® will unroll itself with a minimum number
of laborers to assist in the installation of the AquaDam®. Ropes can be used to
turn the AquaDam® in places where it is too deep for laborers to stand. Head
pressure from one side of the AquaDam® to the other should stay equal, making it unnecessary to maintain head pressure inside the AquaDam®. Laborers need
to guide it in the right direction.
The rolled AquaDam® should start at the top of the riverbank or berm. The end of
the AquaDam® must be raised higher up the starting bank than the estimated
height of the fully inflated AquaDam®. Gravity keeps the water used to fill the
AquaDam® from flowing back out the elevated end. The start of the AquaDam® must tie into something (like a bank or berm) or water would just pour
around the end.
