Choosing the right equipment is key to the economic and technical success

of any vibration driving job. Parameters such as the size and drive output

of the vibrator must be matched to the length and weight of the pile and the

soil conditions.

In particular MÜLLER-vibrators with resonance-free starting and infinitely variable amplitudeas well as “two-in-one” vibrators (HHF series)with stepwise variable amplitude and frequencyare suitable for virtually all applications. Forstraightforward jobs, these two model series arecomplemented by vibrators with fixed eccentricmoment.

Diesel-hydraulic power packs with moderncontrol and operating systems are available invarious output classes to match vibrator sizeand driving requirements.

To ensure a secure connection between pileand vibrator, MÜLLER supplies a wide range ofclamping devices and adapter plates for allapplications.

For smaller jobs, MÜLLER offers powerful yetcompact vibrators with fixed and variable ampli-tude for attachment to hydraulic excavators.Leader-mounted vibrators with variable ampli-tude are specially designed for attachment totelescopic leaders.

MÜLLER also provides related accessoriessuch as data logging systems, adapter platesand drill drives for preparatory drilling.

Their ease of operation, low maintenance re-quirements and long service life make MÜLLER-vibrators both economic and dependable.

How MÜLLER-vibrators work.

MÜLLER-vibrators with fixed eccentric moment (H series)The vibrators are fitted with eccentrics which generate a fixedeccentric moment of 25 or 50 kgm. For continuous use or usein extreme climatic conditions, vibrators can be equipped witha forced lubrication system including oil cooling (H3 series).

High-frequency MÜLLER-vibrators with stepwise variableeccentric moment (HHF series)The vibrators in the HHF series are suitable for a broad range ofapplications. The eccentric moment can be increased or reducedin steps by adding/removing additional weights, allowing onevibrator to achieve different amplitudes and frequencies. Eccentricmoments of up to 190 kgm can be generated.

High-frequency MÜLLER-vibrators with variable eccentricmoment (HFV series)When starting these vibrators, the eccentrics are arranged in suchas way as to mutually balance out the centrifugal forces theygenerate and thus prevent any vibration. Once the required fre-quency has been reached, the eccentrics are turned counter toeach other so that the centrifugal forces act in the same directionand generate vibration. This makes it possible to avoid passingthrough the resonance frequency of the soil (approx. 10 to 25 Hzdepending on soil type) during starting and stopping. At present,the eccentric moment of models in this series can be variedbetween 0 and 62 kgm.

EEcccceennttrriicc mmoommeenntt MM [[kkggmm]] MM == GG ·· rrThe eccentric moment is the measure ofunbalance. As a determining factor foramplitude it is a key parameter for drivingoperations.

SSppeeeedd ((ffrreeqquueennccyy)) nn [[rrppmm]]The speed dictates the vibration frequencyof the system. The vibrations are trans-ferred via the pile to the surroundingsoil, significantly reducing the surfacefriction between pile and soil. High fre-quencies counter the unwanted spreadof vibrations in the soil.

The centrifugal force must be highenough to overcome surface frictionbetween pile and soil. Centrifugal forceplays a major part in reducing surfacefriction and provides impact force toovercome tip resistance.

Together with centrifugal force, amplitudeis a measure of driving performance.A large “stroke” and high “impact force”ensure good driving progress. Whendriving and extracting in cohesive soils,the elastic connection between pile andsoil can only be broken if the amplitudeis high enough.

Transmission of the pile acceleration tothe surrounding soil causes the displace-ment of the particle structure and re-duces particle friction and soil resistance.Acceleration is indicated as the ratio ofacceleration to gravity:

This ratio corresponds to:

The value can lie between 10 and 30.

DDrriivvee oouuttppuutt PP [[kkWW]]The drive unit must be powerful enoughto generate the moment needed to main-tain the centrifugal force of the vibrator,even in difficult ground. The drive outputshould be 2 kW per 10 kN centrifugalforce.

Vibrator selection

The graphic provides help in determining the required centrifugalforce or in selecting the right vibrator based on soil conditions,pile weight and driving depth (see above). Mark a point on theleft-hand side of the table representing the maximum driving depth,and another point on the right-hand side marking the maximumpile weight. At the point where this line crosses the soil data linefor your project, draw a vertical line to the vibrator models.This provides an overview of the units which can be consideredfor your requirements. To determine the exact model, we canoffer competent advice taking account of site-specific, geologicaland technical requirements.

Importent details

• For high-frequency vibrator applications, the centrifugal forces determined in this way should be 30% higher.

• Use of additional aids such as flushing pipes or preparatory drilling can significantly increase the driving performance ofa vibrator.

Key vibration technology data

Choosing the right vibrator for the job mainly depends on pile size,driving depth and soil conditions. The greater the driving depthand the harder or more compact the soil, the higher the centrifugalforce and amplitude required. Centrifugal force and amplitudeneed to be high enough to overcome the surface friction and tipresistance between the pile and the surrounding soil. Key vibratordata in this context are shown in the following descriptions andformulae.

MÜLLER-vibrators. HHF series with stepwisevariable eccentric moment.

The vibrator can be adapted quickly to differentsoil conditions by a simple system of adding orremoving weights, allowing the eccentric momentto be varied. For example, if high frequency isrequired for work in loose sand, the additionalweights can be removed simply on site to achievehigh frequencies with the same centrifugal force.

MÜLLER-attachment vibrators.Powerful, compact, easy-to-use, safe.

Selection, mounting and handling

The vibrator is attached to the stick of the exca-vator and powered by the excavator’s hydraulicsystem. A stick tilting section is needed to operateand control the vibrator. The special design of thepush head allows additional static force to beapplied to the pile by the excavator boom, whichcan greatly enhance driving performance. Thechoice of vibrator depends on the available enginepower, oil flow rate and pressure as well as thesoil conditions.

Using MÜLLER-leader-mounted vibrators

MÜLLER-leader-mounted vibrators in combinationwith proven variable moment control are idealfor driving and extracting steel sections such aspipes, sheet piles and beams and for use in foun-dation work such as the construction of compac-ted gravel or sand piles etc. They are slim enoughto drive and extract small single piles and to work

in tight conditions. Resonance-free starting andstopping protects both the surrounding area andthe carrier from damaging vibrations and emis-sions.

Logging parameters such as frequency, pressure,depth etc. is of great importance in civil and spe-cial engineering work. These data are frequentlythe only way of identifying obstacles or variancesfrom the expected structure of the subsoil.

Various sensors for measuring depth, flow rate,vibrations etc. can be connected directly to adata logger and the registered data printed outas a record of vibration work.

14 15 Special applications.Custom solutions.

Vibration and tamping system:

A wide variety of systems and processes canbe used to improve the subsoil for constructionwork. One simple and particularly effectivemethod is soil improvement through self-com-paction or the addition of suitable materials.The MÜLLER vibration and tamping system isideal for this. Depending on the material added,it can be used to produce vibrated concretepiles, compacted gravel piles and stone/mortarpiles. The material runs from the hopper via theinner pipe to the outer pipe, and from there intothe cavity in the soil created by vibration driving.This method produces homogeneous stone orconcrete piles with a very high level of compac-tion. Ground improvements can also be madein loose, non-cohesive soils by vibration (self com-paction).

MRC system:

Loose to medium-dense gravel and sand canbe effectively compacted by displacement toimprove load-bearing capacity. Non-cohesiveground such as this can be compacted usingthe MRC (Müller Resonance Compaction) pro-cess. This process is based on transmitting thevibrations generated by the MÜLLER-vibrator tothe ground via a compacting pile, thus settingup resonance vibrations in the soil. All importantcompaction readings as well as performancedata are registered and directly displayed tothe machine operator. In this way, the variable-frequency vibrator can be adjusted to matchthe ground conditions.

Driving direction0.5 m to 1.0 m


Thin diaphragm wall:

Thin diaphragm walls are an economical way ofproviding vertical sealing in hydraulic and foun-dation engineering. This method is mainly usedin dikes, dams, landfills and to contain subsoilcontamination.

To produce a thin diaphragm wall, a steel beamwith a wider bottom end is driven into the gro-und to be sealed using a MÜLLER-vibrator. Thesteel beam is equipped with flushing or slurrypipes. In this way, the gap created and part ofthe surrounding soil is filled/mixed with slurry.A roughly 50 cm deep flow trench in the narrowwall axis takes up excess slurry and compen-sates for slurry losses. By vibration driving thesteel beam with an overlap, a narrow sealingelement is created. Depending on the soil quali-ty, wall depths of up to 30 meters are possible.

DYSTAFIT© :

Expensive ground improvement measuresand maintenance costs for rail track structurescan be reduced if the long-term dynamic stabili-ty of their subsoil/substructures can be verified.To provide this in-situ verification, ARCADISTrischler und Partner in collaboration with Thyssen-Krupp GfT Tiefbautechnik, Alsfeld developed thepatented mobile test unit DYSTAFIT© on behalfof PBDE, Leipzig. Using the MÜLLER-vibrator, thesubsoil/substructure can be subjected to dynam-ic loads in a frequency range between 5 and45 Hz. This test set-up allows stability levels tobe measured in any ground which is susceptibleto settling, sinking or shifting. DYSTAFIT© canalso be used to test the effects of increasedspeeds on lines modified for high-speed trains.In practical testing, up to 3 million load cycleswere performed for each test cross section incontinuous operation.
