Jetting Platform
Jetting Platform
The jetting assistance is used during the
installing of sheet piles, vibrating beams and
pipes.
It is a successful method of reducing the end
bearing in the pile foot, the skin friction as
well as the friction in the interlocks. And it
loosens the soil. The jetting assistance per-
mits a reduction in the vibrating times; the
vibrated material is largely protected from
deformation; equipment overload is prevented;
and soil vibration is reduced to a minimum.
The Jetting Platform Model 2 – 8 consists of
the following components:
• Water storage container with a capacity of
approx. 8 m³, with manhole, level regulating
device via pressure sensor.
• 2 centrifugal pumps, each with a pumping
capacity of 20 m³, and a maximum
pumping pressure of 25 bar, driven by
30 kW electric motors.
• 2 fequency converters to adjust the
frequency of the pumps.
• Piston compressor, capacity max. 1319 l/min,
max. pressure 15 bar.
• Compressed air reservoir capacity 250 l.
• Electrical switch cabinet with connecting
socket in accordance with protective sys-
tem IP 54 according to VDE, triangular star
switch, safety device and fuses for the cen-
trifugal pumps, completely wired, CEE cir-
cular connection 125 ampere.
• Separate power connection for loading
pump with control via level regulator in con-
tainer.
• Inlet valve with intermediate flange valve
and electrical drive 220. V
• 4 connections for water flushing hoses with
flow controls and pressure gauges.
• Connection for compressed air.
• Radio remote control with control of all
functions and display.
• The entire jetting unit is installed in a 20-ft.
container.
• Measurements: 6055 x 2438 x 2591 mm.
• Weight: approx. 5100 kg.
