Javeler was awarded the contract to dredge
32,000 cubic yards of contaminated sediment using the
Toyo submersible agitator dredge pump system due to the
limited turbidity created when dredging as well as the
high solids content when submerged in material. The
material is being pumped 2,000 feet to a treatment/
dewatering process.
Exact dredge
positioning was obtained with a Trimble GPS system
mounted on the end of the crane and a depth sensor.
A magnetic flow meter/density meter provided flow rates,
percent solids and production numbers.
An electronic tide gauge corrected for the 12’ tides.All information was sent to a laptop
computer in the operators cab.
A Trimble dredge software package receives the data and
displayed live readouts/contours/3D visualizations.
Javeler Construction provided both
equipment and personnel necessary to perform maintenance dredging for a
neighborhood association. Javeler removed sediment from certain areas of the
lake and transported said sediment to a central disposal area within the lake.
The project was a success and both parties were very pleased. The association
was a pleasure to work with.
Javeler
used a simple dredge system to excavate 25,000 cubic yards of silt along 900’ of
dock frontage. A 40 ton crane mounted on a 65' x 35' barge with 60' spuds
supported a 10" Toyo submersible agitator pump, which dredged the silt and sand
to grade at minus 40'. A 300 kW generator mounted on the back of the crane
provided power to the 150 hp dredge pump. Material was pumped through 100' of 10
inch floating hose to a diesel driven booster pump on the barge, then through
7,000’ 12" HDPE pipe to the Corps disposal site.
