2. Introduction
How does Sonic Drilling work?
Sonic drilling is a soil penetration technique that strongly reduces friction on the drill string and drill bit due to
liquefaction, inertia effects and a temporary reduction of porosity of the soil. The combination makes penetrating
a large range of soils easy for our Sonic rigs and tooling.
Liquefaction
When you use a sonic drill head, the entire drill string is brought to a vibration frequency of up to 150 Hz. This
causes a very thin layer of soil particles directly surrounding the drill string and bit to loose structure. Instead
of a stiff mass, the soil behaves like a fluid powder or paste. This fluidization, or liquefaction, extremely reduces
friction.
The SmallRotoSonic 2x7 drill head

The SmallRotoSonic 2x7 drill head uses vibration combined with rotation and is a soil displacement drilling
method suitable for most soils and geological conditions. In certain cases the drill method can be assisted with
simultaneous water or air injection by a swivel.
The casing allows equipment to be installed into the ground: explosives for seismological research; 1-inch and
2-inch monitoring wells, multilevel wells or geo-sensors.
SmartWells and seismic explosives are all installed with parallel repair of impermeable layers that have been
drilled through. We supply pre-shaped bentonite products with diameters compatible with our GP63, GP88 and
GP100 casing for use with our SmartWells and seismic material. In approximately 120 hours they swell and plug
the hole when the casing has been pulled up.
2.1 User limitations
Please take note of the following user limitations.
Operate the SmallRotoSonic head only with Eijkelkamp SonicSampDrill supplied and/or approved
drill rigs.
Drilling in soft/medium/hard formations only use Eijkelkamp SonicSampDrill supplied and/or approved
tooling.
Vertical drilling for inclined drilling max. 45°from vertical in same direction as head tilt, and only while
using an appropriate centralizer to secure proper alignment of drill string with foot clamp.
3. Description Sonic Drill head SRS 2x7
The Sonic Drill module consists of a high-frequency vibration unit / oscillator block, which is mounted in a
frame with vibration isolators. The standard SmallRotoSonic 2x7 drill head unit has two vibration isolators
(silent blocks) on each side (four in total). A separate hydraulic motor enables rotation during vibration or for
mounting and breaking casing.

5.2 Noise production
Noise measurements have been carried out at several distances of the drilling module. The derived A-weighted
sound power level (LWA) of the Sonic drilling module, excluding the contribution of the hydraulic power unit,
is 104 dB(A). In table 1 the sound power level is given in octave bands and in dB(A).
Table 1. Sound power level (LWA) of the Sonic drilling module (P1.27-2); excluding hydraulic power unit
Centre frequency octave band 63 125 250 500 1000 2000 4000 8000 Hz
LWA in dB (re 10-12 watts) 74 96 86 94 97 100 95 92 dB
LWA in dB (re 10-12 watts) 104 dB (A)
The equivalent sound pressure level (Leq) at 10 m distance from the drilling module, excluding the contribution
of the hydraulic power unit, is 75 dB (A).
The noise level at the operating panel of the drilling machine, excluding the contribution of the hydraulic power
unit, will be between 89-94 dB (A) (corresponding with the levels measured respectively 1 and 2 m distance from
the heart of the drilling module).
* Expressed in a formula: Lw=Lp+Dgeo+Dground

with: Dgeo = geometrical/spherical attenuation (in this case: 10 log 4.π.r2)
Dground = ground reflection (in this case: -2 dB)
6. Functioning
You must have read the safety instructions before you start drilling. The applied drilling techniques
are powerful. Using it in an impatient manner is dangerous. Respect safety instructions and take care
to follow all instructions in the manuals.
6.1 Warming up the drill head
Moderate to warm season:

Prior to full operation, warm up the drill head for a few minutes or so, with 25 rpm rotation. Then (with) a few
seconds of gentle vibration and 50 rpm rotation. Also operate the other hydraulic powered functions (mast
pul-up/down, etc.).
Extend to a total of five minutes if temperatures are between 5...10 °C.
Cold season (drill head/oil temperature below 5 °C):

Repeat the above described sequence but continue rotation until warming up of the oil is noticed. Only then
continue with rotation (5 minutes). Finish with a few seconds of gentle vibration to check the correct operation.
When the drill head is to be used under arctic conditions the use of Aerohydraulic 520 oil (or similar) is indicated.
 Contact the technical department of Eijkelkamp SonicSampDrill before operating in temperatures of

-15 °C.
6.2 Free movement of the drill head
The vibration + rotary unit is suspended between vibration isolators and can move 70 mm up and 70 mm down.
The vibrated spindle can simultaneously be rotated by the rotary motor on top of the vibratory unit; clockwise
only. The vibration unit has a stop both at the top and bottom. This stop is reached at a pulling force of more
than 55 kN.
 During vibration the vibratory unit should never touch the drill head frame. If this happens a loud
metallic sound is produced, but this should be avoided at all times.
6.3 Switching from rotary drilling to vibration and visa versa
During drilling operations, the rotation and vibration functions of the SmallRotoSonic 2x7 drill head can be
activated at all times; separate from each other or simultaneously. The rotation function is also used to make
or break threaded connections. Never use the vibration function then!
 To prevent high wear of casing threading it is important to neutralize the position of the vibratory
block within the frame. When unscrewing a casing the drill head should be allowed to move up. When
connecting a casing it should be allowed to move down. While tightening or un-tightening screw
connections of rods, slowly move the running carriage down (tightening) or up (un-tightening). In this
way the stops will not be reached. It will also increase the life time of your casing threads. If present
on the rig use the weight compensation function, otherwise you may consider mounting one to prolong
the longevity of casing threading.
6.4 Feed force information
The maximum feed force can be applied to a drill string if the drill string is pulled without the use of
rotary and/or vibration functions. Pulling up the drill string with maximum force will result in a physical
contact between the vibration block and the stops in the sonic frame. This is allowed.
6.5 Overheating
Warning:
During intensive use eccentric housings may overheat. As a rule, keep in mind never to exceed a
continuous vibration time of 15 minutes.
This time may be shorter in case of heavy drilling circumstances or high rpm’s of the eccentrics (slow down the
vibration intensity if this is not required!!). Check temperatures of eccentric housings and casing connections.
When too hot, activate clockwise rotation for some 10-20 minutes. Then allow all components (oil, cooler, drill
head) to cool for 30 minutes during a complete standstill of the rig.
Consider creating another borehole or start the drilling process with more patience (slow down). When the
problem persists consider skipping to another drilling technique.
Keep the radiator(s) clean.
7. Safety
 Not all tools can withstand high-frequency vibrations. Only use the tools supplied or tools that have
been approved by Eijkelkamp SonicSampDrill.
Avoid unauthorized people coming any closer to the rig than 10 metres.
Work clothing. Always wear safety shoes or safety boots, a safety helmet and a pair of sturdy gloves.
Do not wear loose-fitting clothing or jewellery or items of clothing that hang loose.
Always wear ear protection. This applies to the operator as well as the assistant operator (everybody
within a range of approx. 7 metres from the noise source).
Do not start drilling unless the assistant operator is at least 2 metres away from the drilling mast.
 Check joints according to the maintenance schedule or more often if the equipment is used under severe
conditions (if jumping appears-drilling in very hard formations). Use locking techniques according to
the instructions later in this manual. Use a torque wrench and the torques specified in the table at
the end of this manual. Any strange noise is an alarm to check all joints!
Stop drilling immediately if one of the following is detected:

- Oil leak(s).
- Unusual noise.
- Violent horizontal shaking of the oscillating drill head (broken casing, broken or jumped
synchronisation belt, sheared off/broken rubber buffer).
Do not touch vibrating parts. Although hardly visible, the frequency and amplitude will cause injury.
Use the oscillating drill head only with tools approved by the manufacturer.
When drilling is started the lower end of the casing needs to be guided to prevent any sideways
movement. Use of a guide sleeve or centralizer flaps is recommended. This may be done by partially
closing the foot clamp and then carefully exerting pressure and/or making gentle rotations for the
first 50 cm
Do not use the vibratory unit to warm up the hydraulics! Use the rotation function for this. (See 5.1
Warming up the Drill Head for warm up procedure)
When in doubt about any aspect of the drill head use, please contact your supplier.
8. Trouble shooting
All hydraulic functions refuse to act
• The hydraulic circuit is not running or no electricity for the sensors.
• The emergency button (e.g. of a hydraulic power pack) has been pressed.
Oscillating drill head shakes instead of vibrating purely up-and-down

• Check if the synchronization belt is visibly intact (rear of the drill head unit). If the belt is broken replace
immediately following the instructions in the separate manual.
• Check correct timing of belt.
• Check the rubber buffers. They should have the same age and level of wear. Check on cracks in rubber.
Replace left and right isolators simultaneously when in doubt.
Oscillating drill head will not start properly

Check if pump motor set on drill head is running. Lubricating pressure has low and high pressure limit. Disconnect
the drill head from the drill string. Rotate the drill head clockwise 1-2 minutes. The oil is now drained from the
eccentric housings and the sonic head should function properly again. Then try the vibration function. In cold
conditions (0 to -35°C) this needs to be increased to 10-20 minutes. If frequent malfunctioning at starts occurs,
check the oil drain pumps. If lube pressure exceeds operating range Sonic vibrations will not start and or cuts
down automatically.
Strong increase in noise
The drill string touches the foot clamp of the drilling machine
In hard layers of soil or rubble and with high force is exerted some drilling machines will drift away easily. The
drill string can also drift away underground in layers containing rubble. Try to avoid this situation at all times
since it may be very difficult or impossible to correct this situation. If possible, reposition the drilling machine
above the drill string. Prevent the rig from drifting away from the casing by constantly monitoring the vertical
movement of the mast compared to the soil. When reaching a layer with boulders or rock severely slow down
lowering speed and, if mounted, activate the float function. If the problem persists install the machine elsewhere.
The drill casing in the string have loosened themselves

This can occur when the casing has not been tightened sufficiently. Fasten the whole string again. Replace worn
casing in time ! Use a lubricant (bio-grease for non-monitoring wells or a special non-interfering lubricant for
the installation of environmental monitoring (sampling) well).
 Contact your supplier if you are unable to find a cause for your problem.
9. Regular maintenance and lubrication
9.1 Inspection
 Check according to the maintenance schedule:
• Loosening of screw connections. Where necessary, fix screw connections with safety nut or self-locking
material (see further on). It may still be possible for screw connections to loosen, especially during heavy-
duty work like penetrating layers of hard soil.
• Condition of hydraulic hoses and clamps keeping hydraulic hoses separated from each other.
• Check if the synchronisation belt (see rear of drill head) is intact and has the right tension using the
tensioning checking tool (see separate synchronization belt manual).
9.2 Cleaning
• Keep case of the synchronisation belt clean. Particles that come loose may damage or even break the
belt. A broken belt may cause the eccenters to rotate out of tune which will create a vigorous shaking of
the drill head and severe stress on spindle and casing.
• If cleaning the drill head with a high pressure cleaner do NOT direct the water jet towards seals, runners,
sealed or unsealed bearings or sleeve bearings.
9.3 Annual inspection
For a thorough inspection and warrantee reasons it is recommended to have the oscillating drill head checked
by the manufacturer or a B-level Eijkelkamp SonicSampDrill certified distributor every year or after 100 Sonic
head hours of vibration.

Before starting replacements or repairs, please take notice of the following points.
Only trained personnel may work on the hydraulic installation.
When replacing hoses use the exact length and specifications of hose.
Use identical couplings when replacing hoses.
The vibration unit has several factory settings. Do not dismantle the vibration unit. If repairs are
necessary please refer to the supplier.
Bolt connections should come with safety nuts and should be fixed with the correct fasteners.
When Nord-Lock washers are used always replace when reassembling.
Synchronisation belt
For all checks and repairs of the synchronisation belt refer to the separate manual supplied.
Disassembling the vibration unit

• Disconnect and cap all hoses from the vibration unit. Mark the hoses to prevent any errors during
assembly.
• Remove lower rubber buffers by the windows (see drawing in earlier chapter in this manual)
• Remove bolts of both upper rubber buffers and take out the vibration unit using a hoist.
Never try to repair anything on the vibration unit. Always contact the manufacturer. The vibration unit
must be sent to the manufacturer for repair.
Replacement of hoses
Always observe local construction and industrial manufacturing safety requirements when replacing hoses.
Hoses must be able to withstand a 4-fold operating pressure. Replace with hose of same length.

(Threebond 1374 medium strength), SDHM00064 (Threebond 1346B hydraulic fittings) as locking agent. You
will also need activator SDHM00251 (Threebond 3095C) and degreaser SDHM00180 (Threebond 2890B).
• Materials to be locked must be totally degreased and cleaned. Use degreaser SDHM00180 (Threebond
2890B).
• Most suitable degreaser is a degreaser that leaves no residues.
• Never work at operating temperatures below 5 °C. At low temperatures hardening time is slowed down
considerably. Warming parts may be considered. Use a hair dryer to be sure to stay below 50 °C.
• Pre-tensioning of the parts is necessary for optimal locking.
• Make sure that the parts to be locked are smeared completely with the locking agent.
• Screw the parts smoothly by hand driven wrenches (not shocking, as with a pneumatic wrench).
• Be sure that the locking agent can cure well enough in a vibration free environment.
• Note that stainless steel shows longer curing times than Ferro iron.
• Store locking agents in a cool environment, do not use when thickened.
