1) 200kN Stand Alone penetrometer
GeoMil's 200 kN Stand Alone Penetrometer is a versatile unit designed to
be used in a wide range of applications. The special mounting beam
allows for placing the penetrometer on any base, varying from a steel
skid to a truck platform, or an excavator to a jack-up platform or
barge. Please see some
mounting options
to gain an impression of different combinations of penetrometer and
base.
Optionally, the penetrometer can be equipped with an integrated
hydraulic catching clamp in the sounding beam. If the overall weight of
the base is sufficient, i.e. in the range of 21 to 22 tonnes - and by
selecting the appropriate location of the penetrometer in combination
with proper balancing of the weight - the setup will result in 200 kN
pushing capacity.
The penetrometer is hydraulically powered by a seperate powerpack,
driven by a Hatz Silentpack diesel engine. The complete unit is built-in
in a heavy duty framework, providing a robust unit and allowing easy
transport by crane or forklift
Penetrometer and powerpack are connected by means of a set of hydraulic
hoses with quick-couplings.
Alternatively, an electrically driven (400 V, three-phase) powerpack can
be supplied.
2) 150kN Modular Portable Penetrometer
Goods Code : 9015 8019
The requirement to carry out CPT soundings in areas with limited access,
restricted head clearance or simply confined working space is becoming
more and more common.
With the MPP 150© GeoMil now provides a small but powerful
twin ram 150 kN portable penetrometer system.If
it cannot be rolled in place on its small wheel set, the modular design
allows for all components to be hand carried with the weight of the
heaviest items - the hydraulic cylinders - less than 38 kg or 84 lbs.
And assembly and disassembly of the pusher and all its components can be
done in no more than 5 minutes!
With a building height (w/o handles attached) of only 1100 mm and a free
stroke of 550 mm, the pusher is still suitable for 1 m tubes when the
GeoMil push-/pull clamp 3655 is used.
The control valve assembly can be attached to the pusher or placed
separately on a special support.
When soil anchoring becomes necessary, the GeoMil hydraulic anchoring
device "Hygand" can be applied. For locking the MPP 150 to concrete
floors we recommend Dywidag Gewi® soil nails.
The separate power pack provides a wheel-set and strong lifting bars. It
can be connected to the pusher with long hoses (up to 12 m or 40 ft)
provided with leakage free flat couplings. So there is no need to
position it at the CPT site itself.
3) 100kN Stand Alone Penetrometer
Goods Code : 9015 8019
GeoMil's 100 kN Stand Alone Penetrometer is an economic solution for
carrying out CPT soundings where access for larger units is limited or
when only a few CPT operations per project have to be carried out.
To ensure for the appropriate reaction force the unit needs to be
anchored in the ground by means of 2 or 4 anchor screws, locked to the
respective anchoring beams. The anchor screws can be driven by the
hydraulically actuated and hand held anchoring gear
"Hygand".
Like
the 200kN stand alone it can also be mounted permanently onto any stable
base providing sufficient ballast and thus reaction force. Then
anchoring is obsolete.
Optionally, the penetrometer can be equipped with a rotatable all wether
protection box for housing the data acquisition system and notebook-PC.
The penetrometer as well as the anchoring gear is hydraulically powered
by a seperate powerpack with a 5.9 kW 1 cylinder Honda engine, mounted
on a wheel base.
A set of hydraulic hoses with leakage free flat-couplings guarantee for
safe and flexible operation.The 100kN stand alone can be transported in
a van, on a pick-up or trailer and then manoevered by hand since its
mounted on a trolley for easy handling.
4) 50kN Stand Alone Penetrometer
Goods Code : 9015 8019
The
newly designed 50kN stand alone penetrometer forms the consequently
improved "low budget" version of a light and portable pushing unit.
Having its roots in the old
Gouda 2 ton
manual penetrometer, later replaced by a single ram and hydraulically
actuated 50kN penetrometer, it now provides a twin ram construction
allowing for the deployment of all accessory devices for mechanical and
electrical CPT soundings.
The 50kN stand alone provides a perfect solution for all CPT tests in
confined areas such as building basements and tiny back yards or gardens
or if the budget does not allow for a higher investment. Transportation
can be done with any station wagon, pick-up or small trailer and due to
the modular design all components can also be carried or pulled by hand.
Due to the low investment costs but while feasible for all CPT sounding
methods the 50kN stand alone also forms an ideal solution for
educational purposes and will thus provide a versatile and valuable tool
for Universities and research institutes.
The power pack consists of a Honda 1 cylinder 4 stroke engine driving
the hydraulic pump for actuating both, the pusher itself and the
hydraulic anchoring device.
The twin ram construction supports all GeoMil push-/pull devices for
mechanical or electrical CPT and although the stroke is limited to 700mm
the yoke in combination with the
push-/pull clamp 3655
allows for the use of 1m rods as well (electrical CPT only).

Easy to use
Operating under Windows 95/98, the RAS-24 system software has a
familiar point and click interface which is easy to learn and
operate. With buttons, scroll bars and single key commands for
commonly used functions, the RAS-24 user interface is designed to
allow direct access to important system functions.
And setting up the RAS-24 couldn’t be easier. Select the type of
survey you want to perform - refraction, 2D reflection with roll, or
3D - and the RAS-24 configures itself. And when you’re back in the
office, you can review the observers log and view, pick and print
records on your office system using the same software that you ran
in the field.
Expandable
Because the RAS-24 is a distributed system, it provides a unique
flexibility not found in any other engineering seismograph. Connect
one RAS-24 to a laptop and you have a very portable 24-channel (or
optionally 12 channels) refraction seismograph. Connect ten units
together in a line and you have a 240-channel, 2D reflection
seismograph complete with roll. Rearrange those same ten units and
you have a ten line, 24 channel/line 3D system. And no special
hardware is required for any of these configurations. The system
software manages the roll for 2D and the active portion of the
spread for 3D operation so no roll switches or CDP cables are
required. The ability to add channels to fit the job at hand ensures
that RAS-24 will be able to handle all your future exploration
requirements.
Highlights:
-
Expandable in inexpensive 24-channel units. Just add another RAS-24 and the system automatically recognizes it.
-
No roll switch for reflection shooting. Roll is controlled by the system software.
-
No heavy, expensive CDP cables. Uses 12-channel spread cables for all configurations.
-
Integrated 3D operation. The RAS-24 system software manages each line as an independent entity.
-
All testing functions are built in and controlled by the operator from the laptop using the RAS-24 system software. The performance of the entire system may be verified in the field with just two clicks of the mouse.
-
Since the RAS-24 acquisition unit is separate from the controller (the laptop), the controller may be easily upgraded to faster, more capable models as they become available.

TEST DESCRIPTION
A pressuremeter test is an in-situ stress controlled loading test performed on the wall of a borehole using a cylindrical probe which can expand radially. From the test readings, a stressstrain curve can be obtained which yields :
· the Menard pressuremeter modulus
· the creep pressure
· the Menard limit pressure once the volume and pressure calibrations have been performed to allow data reduction.
EQUIPMENT
·THE MONITORING UNIT
Equipped with devices to precisely regulate the pressure applied to the probe and to read its volume changes with pressure increments and time. A gas cylinder provides the pressure source. The box stands on a tripod. It includes a 800 cm3 volumeter with a sight tube, a main pressure regulator, a differential pressure regulator, pressure auges 0-2.5 and 0-6 MPa for the measuring and the guard cells (0.06 and 10 MPa as options for soft soil and weak rock tests), and the necessary valves and couplings.
·THE PLASTIC TUBING
This coaxial or twin tubing, flexible and of high resistance, connects the probe to the monitoring box with minimum Deformations.
·THE 3-CELL PROBE
It includes a central measuring cell, filled with water. Its volume changes are read on the monitoring box volumeter. The probe is totally protected by a rubber cover which is inflated by the gas to form the 2 guard cells. Pressure applied to the borehole walls are kept constant along the 3 cells through the differential pressure regulator to ensure a true cylindrical deformation along the measuring cell.
TEST PROCEDURE
The borehole is drilled so as to minimize wall disturbance and keep a cavity diameter compatible with the probe size. The probe is lowered into the borehole to the required test depth and the pressure is applied by equal increments. Pressure and volume readings are taken on the monitoring box. In gravely soils under water table where the borehole would cave-in, the probe can be inserted in a specially designed slotted tube which is hammered or vibrodriven into the soil. Specially fitted probes can also be part of a string of pipes to be forced into soft soils, sometimes together with a static cone penetration device.
DATA LOGGER GEOSPAD
The GEOSPAD is a computerized system designed for automatic data logging of pressuremeter test readings. It is a field device, ruggedly built, compact and reliable. It can be used with most of the Menard-type pressuremeters, which keep their full performance range, whether or not they are used with the GEOSPAD. Quality of reading is improved, thanks to recordings which are exactly carried out at 1, 15, 30 and 60 seconds with better accuracy : 1 cm3 on the volumes and 1 kPa on the pressures. is one of the main points fixing the quality of a test. GEOSPAD checks the pressure balance between measuring cell and guard cells at all time and displays its actual value, which can be compared to the required value. It conforms to the standards NF P 94-110-1 and ASTM D-4719-87, and provides the perfect mean to check the test conformity.
GEOSPAD prints all tests curves and data, and records them on a memory card. Data can be processed on a PC, with the XPressio software, that also allows treatment of manually input data. It processes the pressuremeter test data to obtain the Menard E-Modulus and the Menard limit pressure, either automatically or manually (AFNOR or ASTM standard). It also displays and prints out quality graphs for pressuremeter stress strain curves.
