possibility of using irrigation water if precipitation was scant during the fall and
early winter, but this was not necessary.
Conclusion
A GWFV wall system was selected to construct bridge-approach embankments
for a culvert-elimination fisheries project
in Pend Oreille County in northeastern
Washington state. Suitable structural fill
soil and topsoil were located at nearby borrow sources, and large construction equipment (such as dozers, trackhoes, large
side-dump trucks and vibratory roller
compactors) could be used effectively due
to ready access from the existing roadway. Compaction control was monitored
regularly throughout embankment construction using a nuclear moisture-density
gauge per project specifications.
After the construction crew had been
trained and gained some experience with
the wall system, installation rates typically ranged from 25 to 40 square feet
(2.3 to 3.7 m2) of wall face per hour. For
project sites with more difficult access or
limited to smaller construction equipment, the installation rate likely could
be reduced by 50 to 75 percent. Figure
10 shows the completed west embankment with excellent vegetation cover 22
months after wall completion.
