Vibro Compaction & Vibro Replacement
VIBRO COMPACTION
2 / www.omsvibro.de Stone Column Equipment
OMS Pile Driving Equipment GmbH. provides a large selection of soil
improvement equipment such as “vibro compaction”, “vibro replacement”
and “vertical drain” depending on the project requirements.
Ground engineering plays an increasingly important role in social and industrial development, especially in connection
with major construction projects such as power stations or the expansion of infrastructure systems (railways, harbours,
airports etc.). The objectives of deep vibro compaction and vibro replacement are to improve the strength and deformation
characteristics of granular soils to a certain degree, so that structures can be supported safely and economically on or below
the improved ground surface.
Vibro compaction and vibro replacement can be another option as technical methods which is used for unfavourable soil
conditions that provide a transition between deep foundation and soil stabilisation. These methods increase the strength of
the weak layer and utilises the benefit of the improved resistance.
At this point, the OMS provides the right soil improvement equipment as a solution for its customers. The vibro compaction
and vibro replacement (stone columns) combined with vertical drain (wick drain) equipment of OMS plays a crucial role in
the market from Germany to Middle East, South East Asia and America Lands.
SOIL IMPROVEMENT METHODS
USING WITH OMS VIBROFLOTS
Vibrocompactionmethodismostlyusedinfinegranularsoilsthatarein
seismic risk and thus, the method itself is suitable for land reclamation
projects to mitigate the risk of liquefaction. This technique is for
densifying sand-like soils on site by means of an OMS Vibroflotation
probe. With the simultaneous vibration and saturation impact, loose
sand particles are repacked into a more compact state and lateral
confining pressure within the sand mass is increased.
Vibro compaction technique is most suitable for medium to coarse-
grained sand with a silt content. Cohesive soils consisting of silt and
clay material does not respond to vibratory compaction. The following
illustration explains the operation:

in land reclamation projects up to 20 - 25 m depth. The quality of
compaction/stone column can be monitored with a data logger supplied
byOMS.Hence,thedepth,compactionrate,timerelatedcompactionand

Single Free Hanging
The single free hanging vibroflotation probe comprises of the same
interchangeable parts as the tandem set. The depth of compaction
or stone column can be deeper, therefore projects that are medium
to small scale are suitable for to be executed with single free
hanging system. Compared to tandem system, crane capacity of
the vibroflotation probe is slightly smaller. On the other hand, just
like tandem system, the quality of compaction/stone column can be
monitored with a “data logger” so that, depth, compaction rate, time
related compaction and withdrawals as well as gravel volume can be
measured and monitored.

VIBRO REPLACEMENT
(Bottom Feed System)
Vibro replacement stone column is a soil improvement system by which
vertical columns of compacted gravel are placed into soil. This is a
technique that builds load-bearing columns made out of gravel or crushed
stones in cohesive soil and granular soil with high fines content.
Vibro replacement stone columns have been used to improve a wide range
of soil from very soft clays and peat to materials marginally suitable for
the vibro compaction method. The equipment used for the vibro
replacement method is (other than for the vibro displacement method)
identical to the one used in the vibro compaction method.
For the operation of vibro replacement columns (stone/gravel columns)
“the bottom feed” process which feeds gravel to the end of the
vibroflotation probe with the aid of pressurised air. For the optimum
performance of this process, OMS has developed the vibroflotation probe
and gravel hooper with pressure chamber. This OMS vibroflotation probes
can be mounted on a existing drill rig or leader, crane or an excavator.

The OMS vibroflotation probe (bottom feed system) with gravel
hooper can be easily mounted on existing drill rig or a leader with a
supervisor from OMS technical team. This particular configuration is
advantageous since the drill rig or leader equipped with a pull-down
system, thus, allows additional pull-down pressure to be exerted
during penetration and compaction.

This configuration is rather easy to mount on a customers’ excavator
by the help of OMS supervision team. It is also easy to operate and
cost friendly, however it comes with stone columns of limited depth.

  • 5. 8 / www.omsvibro.de Stone Column Equipment Single Free Hanging The single free hanging vibroflotation probe comprises of the same interchangeable parts as the tandem set. The depth of compaction or stone column can be deeper, therefore projects that are medium to small scale are suitable for to be executed with single free hanging system. Compared to tandem system, crane capacity of the vibroflotation probe is slightly smaller. On the other hand, just like tandem system, the quality of compaction/stone column can be monitored with a “data logger” so that, depth, compaction rate, time related compaction and withdrawals as well as gravel volume can be measured and monitored.
  • 6. 10 / www.omsvibro.de Stone Column Equipment VIBRO REPLACEMENT (Bottom Feed System) Vibro replacement stone column is a soil improvement system by which vertical columns of compacted gravel are placed into soil. This is a technique that builds load-bearing columns made out of gravel or crushed stones in cohesive soil and granular soil with high fines content. Vibro replacement stone columns have been used to improve a wide range of soil from very soft clays and peat to materials marginally suitable for the vibro compaction method. The equipment used for the vibro replacement method is (other than for the vibro displacement method) identical to the one used in the vibro compaction method. For the operation of vibro replacement columns (stone/gravel columns) “the bottom feed” process which feeds gravel to the end of the vibroflotation probe with the aid of pressurised air. For the optimum performance of this process, OMS has developed the vibroflotation probe and gravel hooper with pressure chamber. This OMS vibroflotation probes can be mounted on a existing drill rig or leader, crane or an excavator.
