Dredged Soil Texture
Dredging mud, clay, fine silty sand, medium fine
sand, coarse sand ,gravel and pebble:
Clay: Ip>17 Fine silty sand: d50%=0.0lmrn, density
(volume-weight)= 1.86 t/m3
Medium fine sand: d10%=0.31mm, d50%=0.23mrn,
d90%=0.16mrn, without mud
density (volume-weight)= 1.95 t/m3 (the sand pores are
filled with water) Coarse sand: d50%=0.50mrn
Gravel and pebble: d50%=20mm
Loading
1 The dredged soil texture is medium fine sand: the calculated
effective loading time is about 90 minutes when the two drag
heads dredge down to 20m.This loading time is calculated
on the basis that both the two inboard dredge pumps are put into use,
the average density of the soil into the hopper is 1,300kg/m3,
and the average overflow ratio is 8%
2 The dredged soil texture is medium fine sand: the calculated
effective loading time is about 70 minutes when the two drag
heads dredge down to 40m.This loading time is calculated
on the basis that both the two under water pumps are put into use,
the average density of the soil into the hopper is 1,320kg/m3,
and the average overflow ratio is 8%.
3 The dredged soil texture is medium fine sand: the calculated
effective loading time is about 90 minutes when the two drag
heads dredge down to 40m.This loading time is calculated
on the basis that both the two under water pumps are put into use,
the average density of the soil into the hopper is 1,270kg/m3,
and the average overflow ratio is 8%.
4 The dredged soil texture is medium fine sand: the calculated
effective loading time is about 140 minutes when the single drag
head dredge down to 115m.This loading time is calculated
on the basis that single dredge head, the starboard under
water pumps are put into use, the average density of the soil into
the hopper is 1,270kg/m3, and the average overflow ratio is 8%.
Pumping ashore
When discharging above described mixture through a pipeline
of 4000 m length (not including discharge line on board) by
both inboard pumps working in series, the unloading time
for 26000 m3 of sand is calculated at approx. 14 7 minutes.
This time is based on a discharge pipeline diameter of 1000 mm,
a geodetic height of 6 m, and the ashore density is 1350 kg/m3.
In this case the power for the inboard dredge pumps can reach to
5800 kW each.
When both inboard pumps working in series, the ashore distance
can reach 5000m.
