Low vibration areas can be serviced
with steel H beam “soldier” posts and treated
pine sleepers.
The post hole is
pre-drilled and the H beam pushed down as far as
possible.
If further depth is
required, small one second bursts of vibration
are applied.
The sleepers are loaded
into the H beams and pushed down as the soil is
removed from the front of the wall. |

Steel sheet piles are
hammered with a vibratory hammer carried by a
2.5m wide 20t excavator.
Vibration is minimized by pre-drilling the sheet
location and a Seismic monitor and alarm are
attached to nearby structures to warn of high
vibration levels.

Sheet Piling
Q-Pile took delivery of a new
sheet pile vibratory hammer
which attaches to either our new narrow 20t
excavator
or our standard 30t excavator.
The photos show a temporary retaining wall being
installed
prior to excavation for a basement.
The sheets will be removed on completion of the
basement.
We use a seismograph to monitor and record the
ground and
nearby building vibrations; and an alarm unit alerts
the operator to excessive vibration.
Low establishment costs make those small jobs
feasible.
Small Jobs Are Now Affordable !
$550 site establishment and
removal charge for a sheet piling
rig on the Sunshine Coast.
That’s all it costs for our narrow 2.5m
wide 20t excavator rig. |

1100t CRANE ON
SCREW PILES
This 1100t crane and load is
balanced on 4 concrete pads
that are sitting on screw piles
down 12m through soft soil onto the sandstone below.
The load is a 82m long, 184t bridge beam.
The concrete pads were monitored by a surveyor for
settlement
during the lift and none was recorded.
Q-Pile was commissioned to urgently design and
install the pads and piers.
This was achieved within 6 days from the initial
phone call
to the completion of the concrete pour.
We had fantastic assistance from Russell Heale
Engineering
and Rymark Engineers, together with on-site
assistance
from the project team’s welders and concreters.

Deep
piers for a 10 level
building in Ann St, Brisbane
Early in 2008, Q-Pile was
contracted to drill deep piers for a
10 level building in Ann St, Brisbane.
Holes up to 6.0m deep and from 600 to 1000 mm in
diameter were
drilled into a siltstone material using a continuous
flight auger driven
by a 50 kNm planetary drive unit mounted on a 30t
excavator.
On hand was our maintenance van with welding
facilities for hardfacing
the auger flights and for removing and replacing
auger teeth.
Support excavators were on hand to remove the spoil
and construct
pads for the drilling excavator to work from.

2000 kN (200t) capacity screw piles
Q-Pile takes delivery of a new and faster
drive unit
that is capable of installing 200t capacity piles.
This unit is coupled with Australia’s first 200 kNm
electronic load cell which accurately monitors
the installation torque which is the indicator
of the pile’s load capacity.
This unit will twist up and snap a 273mm diameter
pile of 6.4mm thickness with ease!
