Introduction
Within the last few years, various so-called
”one-step” rock bolt systems have been
developed. This is a result of steadily
increasing demands on rock bolting
procedures in underground Mining
and Tunneling and the ensuing higher
demand for self-drilling rock bolts.
The self-drilling rock bolt product family
has now been extended by providing an
expansion element for the
DYWI® Drill Hollow Bar System.
The key factor for the success of this
rock bolt is the combination of the longterm proven DYWI® Drill Hollow Bar
with a robust and innovative expansion
element. The DYWI® Drill Expansion Bolt
is installed self-drilling; borehole drilling
and bolt installation are accomplished
in one operational step. The system’s
adaptability to changing rock and ground
conditions is an important feature of the
DYWI® Drill Expansion Bolt.
Immediately after the self-drilling
installation, an activation of the
expansion element leads to immediate
load-bearing capacity.
The DYWI® Drill Expansion Bolt can
be optionally tensioned following the
fixation of plate and nut. Subsequent
grouting, de-coupled from the actual
installation procedure, permits further
optimization of installation cycle times.
The DYWI® Drill Expansion Bolt is
available in two different versions.
Type M is mainly used for systematic
rock bolting in underground Mining (see
separate brochure). Type T is used for
rock bolting in hanging wall areas and in
applications that require an extension of
bolts using couplings.

Introduction
The DYWI® Drill Hollow Bar System is a
self-drilling reinforcement element used
in Civil Engineering and underground
construction. The broad field of
application ranges from soil nails and
anchors to micropiles and rock bolts.
Neither difficult ground conditions nor
unstable boreholes are limiting factors
for the application of the DYWI® Drill
Hollow Bar System. In addition to the
applications mentioned above, the
DYWI® Drill Hollow Bar System is also
used as a forepoling element (spile)
or as an injection lance for ground
improvement or cavity filling.
DYWI® Drill Sealing Couplings, Lock
Couplings and Post-Injection Couplings
complete the range of premium quality
system accessories and supplement the
DYWI® Drill standard coupling.
The DYWI® Drill Expansion Shell permits
an immediate and secure anchorage
of hollow bar tension members in
pre-drilled boreholes. For challenging
and demanding rock bolt procedures,
DSI also offers the DYWI® Drill S-D
Expansion Bolt (see separate brochure).
Angle compensation plates allow a
safe anchorage even in large angular
deviation. Spacers and drill bit
adapters are additional accessories for
installation.
21
DYWI® Drill Sealing Coupling
The DYWI® Drill Sealing Coupling allows
an optimized installation procedure with
regards to the leak tightness of the drill
string.
This advantage is especially significant
for simultaneous drilling and injection
operations.
Specifications
Technical Features
Accessories
■■ Available for series R32, R38 and R51
■■ Handling during installation is the
same as for standard couplings
■■ See DYWI® Drill Hollow Bar System
leaflet
■■ A sealing ring inside the coupling and
chamfered hollow bar ends ensure
optimum leak tightness
■■ Mortar-Mixing and injection pumps
Due to the design of conventional
couplings for standard applications, the
absolute leak tightness of the couplings
cannot be warranted when applying
standard flushing pressures.
■■ Suitable for all standard DYWI® Drill
system applications
■■ Simultaneous drilling and grouting
using rotary injection adapters
(flushing heads)
■■ Drilling operations with increased
demands in terms of occupational
safety and cleanliness
Main Advantages
■■ Targeted and safe injection of the
flushing and/or injection medium
■■ DYWI® Drill Sealing Couplings ensure
leak tightness when applying standard
flushing pressures
■■ Easy application; same operating
principle as for standard couplings
■■ Designed for the highest load-bearing
capacities

■■ Flushing heads
DYWI® Drill Lock Coupling
When using standard couplings for
installation, couplings inside the
borehole may loosen due to hammer
strokes applied in the course of drill
string extension. There may be no
external signs for this failure.
Faulty installation may be caused by
worn out coupling adapters, damaged
or missing clamping jaws, or loose
couplings if non system-conform
components have been used.
The DYWI® Drill Lock Coupling prevents
a loosening of couplings inside the
borehole – the hollow bar is installed
continuously in one piece.
Main Advantages
System Description
■■ Suitable for all standard DYWI® Drill
system applications
■■ The DYWI® Drill Lock Coupling does
not detach itself during a clockwise
rotation of the drill string
The standard coupling is replaced by a
DYWI® Drill Lock Coupling.
■■ Trouble-free extension or de-coupling
of the drill string
During the counter-clockwise rotation
of the drill string, the inside locking
mechanism (toothed gear with radial and
longitudinal teeth) cuts transverse ribs
onto the hollow bar. Thus, the hollow
bar coupling is locked against clockwise
rotation and loosening.
■■ Rotary-percussive installation (drilling
direction: counter-clockwise)
■■ Longer hollow bar members with more
than one coupling
■■ Structures with increased demands in
terms of occupational and structural
safety
■■ Installation of the DYWI® Drill Hollow
Bar System using drill booms without
clamping devices
■■ Especially suitable for free length
sections
■■ Controlled removal of defined hollow
bar sections by the selective use of
standard couplings and lock couplings
The DYWI® Drill Lock Coupling is
optionally available with a one-sided or
double locking mechanism.
■■ Rehabilitation and re-working of old
drifts and tunnels

DYWI® Drill Post-Injection Coupling
By default, the annular gap between
hollow bar and ground is grouted via
the outlet port at the drill bit to achieve
improved load transmission.
The DYWI® Drill Post-Injection Coupling
allows the targeted post-injection
through the cleaned inner hole of the
hollow bar using different injection
media.
These injections can be carried out
for ground improvement, sealing, or
compensating grouting.

is achieved by an activation of the

Introduction
Anchors and rock bolts, which are
commonly assigned the general
term ”rock bolts”, are used for rock
reinforcement in Mining and Tunneling.
Rock bolts limit the loosening of
blocks out of the rock mass and shear
displacements. Furthermore, the
frictional force between individual rock
layers is increased.
GEWI® Mining Anchors and Mechanical
Anchors Type ALWAG are wellestablished systems with variable anchor
lengths. The maximum load-bearing
capacity of these mechanical anchors is
mainly determined by the stability of the
borehole (ground characteristics), the
amount of the pre-tensioning, and the
design of the expansion shell.
Anchors with a variable anchor length
enable pre-tensioning and thus an active
force transmission.
Rock bolts such as SN-Anchors or
the DYWIDAG THREADBAR® are fully
grouted over the whole length and are
usually installed untensioned.
Generally, this does not apply to resin
rock bolts, which can be actively pretensioned using resin cartridges with
different curing times.
Which rock bolt system is the best one
to use depends on a variety of factors,
which have to be considered in each
individual case. DYWIDAG-Systems
International has longtime experience in
the development, production and supply
of mechanical anchors and rock bolts.

SN-Anchors
SN-Anchors, also known as mortar
embedded concrete reinforcement
steel anchors or Store-Norfors-Anchors
(named after the first place of installation),
are used for rock reinforcement in
underground Mining and Tunneling.
For special requirements in Tunneling,
especially rock reinforcement in squeezing
ground and large displacements directly
after bolt installation, DSI also offers
SN-Anchors with ALWAGRIP special rib
geometry for an increased load-bearing

ALWAGRIP Special Rib Geometry
■■ According to the guideline RVS 8T,
Federal Minstry for Transport,
Innovation and Technology, Austria
■■ The rib geometry of conventional
SN-Anchors is in accordance with
the regulations of concrete steel
reinforcement
■■ Ground deformations in Tunneling
usually occur immediately after the
installation of SN-Anchors, which is
why the requirements for bond strength
development differs from reinforced
concrete construction
■■ Development of ALWAGRIP special
rib geometry in accordance with
the requirements for SN-Anchors in
Tunneling, especially in squeezing
ground conditions
■■ Obtained rib area between 0.02 and 0.04
(cf. RVS 8T, Federal Ministry for Transport,
Innovation and Technology, Austria)
■■ Material characteristics of SN-Anchors
with ALWAGRIP special rib geometry
are considerably better than for similar
anchors and rock bolts with concrete
reinforcement ribbing
■■ The advantages of using a steel grade
with higher yield strength are observable
after a curing time of 12 hours
■■ Examination of the inner bond for two
different anchor steel types depending
on curing time
■■ Results of pull-out tests after
12 hours curing time, bond length

Introduction
Friction Stabilizers are mainly used
for rock reinforcement in underground
Mining. The shaft of the Friction
Stabilizer consists of a metal strip
which is folded to form a slotted tube.
The bolt is installed into a borehole by
applying impact energy. The borehole
features a slightly smaller diameter than
the outer diameter of the bolt tube.
The principle of this anchor system
is based on the bond between the
borehole and the tubular bolt shaft,
caused by applying a force onto the
borehole wall, which generates a
frictional resistance in axial direction.
The main field of application of this rock
bolt is underground metal ore or hard
rock Mining. Recently, a self-drilling
friction bolt system, the POWER-SET
Self-Drilling Friction Bolt, has been
developed in addition to conventional
Friction Stabilizers.

Introduction
The AT - Pipe Umbrella System is a
pre-support measure used in weak
ground conditions in conventional as
well as mechanized Tunneling. Pipe
umbrella pipes increase the stability in
the working area by transferring loads in
the longitudinal direction and decrease
excavation induced deformations.
The system increases safety in the
working area.
Beside this standard usage, the system
is often applied to increase stability in
portal sections and for the re-excavation
of collapsed sections in underground
construction. Another application area is
ground improvement and waterproofing
in combination with all tunnel construction
methods.

Technical Features
■■ Quick length adjustment of the
AT - Pipe Umbrella System facilitated
by piecewise installation
■■ Simple connection of extension tubes
even in restricted space
■■ High drilling accuracy of pipe
umbrella drills
■■ Special pipe coupling types for
different static requirements
■■ The use of the AT - Pipe Umbrella
Automation Unit increases the drilling
progress, minimizes over-excavation
(saw tooth profile), and increases
personnel safety
■■ Application of preventers possible
■■ Recording and control of the grouting
process using a flow-pressure meter
AT - Drilling System
The drilling energy is transferred via
drill rods and an inside adapter onto
the single-use drill bit of the AT - Starter
Unit. The cooling and flushing medium is
immediately transported from the drill bit
front backward inside the umbrella pipes.
After completion of the installation, the
single-use drill bit remains at the toe of
the borehole; adapter and drill rods are
removed and re-used for consecutive
pipe installations.
■■ Loss or blocking of a drill bit is
impossible because it is fixed
within the starter unit
■■ A single-use drill bit ensures the same
high quality for each drilling process
■■ Application of a single-use drill bit
provides optimum pre-conditions to
achieve the total drilling depth every
time
■■ The drill bit type can be adapted to
given geological conditions
■■ Stable drilling direction due to stable
drill bit orientation
■■ Disconnecting and reconnecting of
drill rods is possible at any time
■■ Small overcutting ensures the lowest
possible stress relaxation
73
AT - Pipe Couplings
The AT - Pipe Umbrella System is installed
with conventional drilling machines.
Single pipes are installed piecewise at a
length that fits the drill boom length.
Type and quality of the pipe coupling
are decisive factors for the maximum
achievable load-bearing capacity of the
support system.
For this reason, three different types of
couplings are available for the AT - Pipe
Umbrella System.
Standard Thread Connection
When using a standard thread connection, an outside and inside
thread is cut into the ends of the pipe umbrella pipes. This type of
coupling reduces the cross-section of the pipe at the area of the
thread connection. Thereby, the section modulus is decreased
as well. Besides the geometrical conditions of the thread, the
overall quality of the pipes is a major concern for the maximum
load-bearing capacity. In general, calibrated tubes reach a higher
resistance against bending than non-calibrated ones.
This connection type can be recommended for the installation
of measurement instrumentations and for ground-improving
injection works.
■■ Simplest connection type
■■ Installed tubes show a constant inner diameter
■■ The stiffness of the connection is considerably lower than
the stiffness of the standard pipes
■■ The rupture load of the connections is comparable to the
design load of standard pipes; it is clearly lower for
non-calibrated tubes
■■ Further decrease of the load-bearing capacity if mistakes
occur during screwing or grouting of the pipes
■■ A lower load-bearing capacity can only be compensated by
a higher number of pipes
■■ Dislocation of the coupling positions in the longitudinal
direction does not increase the load-bearing capacity
■■ Installation can be accomplished with or without an
AT - Pipe Umbrella Automation Unit
Squeezed Connection
A squeezed connection consists of a reduced pipe end which is
force-fitted with its counter piece. In the coupling area, the cross
section stays constant and the section modulus is decreased.
■■ The ultimate load of this connection is higher than the elastic
design load of a normal pipe (> 1.5)
■■ Transition from elastic to plastic material behavior begins at
approximately ¾ of the elastic design load (standard pipe)
■■ Reduction of the inner diameter in the connection area
■■ Reduction of the stiffness against bending in the connection
area
■■ Installation can only be accomplished with an AT - Pipe
Umbrella Automation Unit incorporating a squeezing unit
74
Usage of this connection type can be recommended for all
advances where a pipe umbrella is installed because of its
static load-bearing capacity.
AT - Pipe Couplings
Nipple Coupling
Nipple couplings are an additional steel nipple where a thread
connection is pressed and welded into both ends of the extension
tubes. This ensures that the section modulus at the coupling is
never lower than the section modulus of the standard pipe.
Usage of this connection type can be recommended for advances
where the static load-bearing capacity is required to achieve stable
conditions and settlement limitations are part of the design.
■■ The elastic design load is equal to the one of a
standard pipe
■■ Stiffness in the elastic range is comparable to the one
of a standard pipe
■■ Reduction of the inner cross-section
■■ Installation can be accomplished with or without an

Introduction
The AT - TUBESPILETM forms part of the
POWER SET product family. It qualifies
perfectly as a pre-support system in
conventional Tunneling and is classified
as a spile.
The application of the AT - TUBESPILETM
permits the stabilization of local
instabilities in the excavation area and the
prevention of ground loosening induced
by installation. In poor ground conditions,
this system is a sound alternative to
conventional ram spiles, rebar spiles, or
IBO - Self-Drilling Spiles.

Introduction
Spiles and forepoling boards are used
as temporary pre-support system for the
working area. They ensure the stability of
the perimeter of the open span until the
primary lining is installed.
Depending on the foundation soil
characteristics, different spile types
are used in order to achieve the best
technical solution for each project.
The products range from rebar spiles,
IBO - Self-Drilling Spiles or the
AT - TUBESPILETM to forepoling boards,
which permit driving in non-cohesive
ground.
85
Rebar Spiles
Rebar spiles and tube spiles are
universally applicable as pre-support.
They can be installed into pre-drilled,
stable boreholes in blocky foundation
soil as well as rammed into soft,
homogenous foundation soil.
■■ Tunnel driving in blocky and jointed
rock mass
■■ Tunnel driving in soft, homogenous
foundation soil conditions
Main Advantages
■■ Practice-proven spile system
■■ Secure and simple installation
■■ Universally applicable
■■ Installation using conventional drilling
machines
System Description
Rebar spiles consist of smooth or ribbed
steel bars that are pointed on one side.
They are installed in pre-drilled grouted
or ungrouted spile holes or are rammed
into the foundation soil. Pre-drilled
rebar spiles are installed in jointed and
blocky rock mass as pre-support against
falling blocks; ram spiles are installed in
homogenous, soft foundation soil.
By ramming, a loosening of the
foundation soil is prevented, and an
optimum initial condition for arching
between the spiles is achieved. Following
driving, the load of the foundation soil
is transferred on the bearings by the
resisting torque of the spiles. These are
the ground ahead of the face and the
support arch in the already supported
excavation area.

is optionally provided with a welded ram
top. The installation is carried out with
conventional drilling machines. The tube
spiles are either installed into pre-drilled
spile holes or rammed directly into the
foundation soil. Pre-drilled tube spiles
are used for jointed and blocky rock
mass as pre-support against falling rock
mass, whereas ram spiles are applied in
homogenous, soft foundation soil.
By ramming, a loosening of the
foundation soil is prevented, and an
optimum initial condition for arching
between the spiles is achieved. Following
driving, the load of the foundation soil is
transferred to the bearings by the spiles.
These are the ground ahead of the face
and the primary lining.

Introduction
PANTEX Lattice Girders have been
developed for special demands in the
field of Tunneling. The PANTEX system
has been extensively tested and used
successfully for numerous tunnel projects
throughout the world.
PANTEX Lattice Girders ensure an
immediate support in the open span area.
Contrary to standard solid-web girders,
PANTEX Lattice Girders are entirely
integrated in the shotcrete lining; porous
zones and shotcrete spray shadows are
avoided.
The load-bearing capacity of PANTEX
Lattice Girders has been investigated with
various loading tests and by numerical
analysis. Flexibility regarding geometry
and bearing capacity characterizes this
passive support system for underground
applications.

Introduction
TH Profiles, HEB Profiles, and UNP
Profiles are successfully used as passive
ground control elements in underground
construction.
Although the importance of conventional
steel support has recently decreased,
it is still successfully used in deep-level
underground coal Mining as well as for
special support in Tunneling and cavern
construction.
Rock bolt straps and mats are used in
combination with rock bolts for securing
the excavation surface. In hard rock
Mining, rock bolt straps are preferably
used, whereas soft rock and coal Mining
prefer flexible rock bolt mats or mesh.

Introduction
Lining Stress Controllers (LSCTM) have
been developed as special supporting
measure for highly squeezing rock mass
conditions. The primary tunnel lining
is divided into several segments by
longitudinal construction joints.
The purpose of this segmentation is
the ability to absorb large deformations
occurring during tunnel driving in weak
ground.
LSCTM steel elements are installed into
these deformation joints. The elements
have a defined workload during
compression so the primary lining is not
damaged.
DYWIDAG-Systems International (DSI)
has long-time experience in the
application of LSCTM elements, which
have been successfully used for many
projects.
113
System Description
■■ Weak ground combined with
high overburden
Compared to the strength of the primary
lining, the load-bearing resistance of
LSCTM Elements is dimensioned at a
lower level. Thus, large deformations
can be absorbed by LSCTM Elements
before the tunnel lining is damaged. The
optimum supporting effect is created by
selecting the best suited LSCTM Elements
and the proper number of compression
bodies which determine the overall loadbearing resistance characteristics.
■■ Fault zones (large displacements)
■■ Swelling ground
■■ Squeezing ground
Main Advantages
■■ Maintenance of supporting forces and
optimum utilization of the load-bearing
capacity of the primary lining
■■ Controlled stress release and
deformability
■■ Steady increase of support resistance
while undergoing large deformations
■■ Rapid increase of support resistance
in slowly increasing deformations
■■ Avoidance of excessive tunnel liner
overstressing
■■ Custom-specific adaptation of the
deformation characteristics of
LSCTM Elements in accordance with
project requirements
■■ The most effective Lining Stress
Controller currently used in Tunneling
114
Single yielding elements are aligned
between base plates. These plates fix
the position of the yielding elements
and limit LSCTM Elements towards the
tunnel lining. Each yielding element
has a factory-set imperfection where
controlled deformations start in case
of excessive loading.

Introduction
The AT - GRP-Injection System is an
AT-SYSTEM with glass fiber reinforced
casing pipes (GRP) which is installed
self-drilling. This system is mainly used
when steel is not desired in the ground
or where injection pipes are excavated
by a TBM afterwards.
The injection pipes permit an insertion of
any kind of ground influencing injection
media into the ground. These injections
may serve for ground improvement or
waterproofing. The AT - GRP-Injection
System can thus be both installed in
jointed rock as well as in weak ground
conditions.
119

mechanized Tunneling
■■ Waterproofing measures near
openings and excavations
■■ Waterproofing measures in waterbearing fault zones
System Description
The AT - GRP-Injection System is
installed piecewise by rotary-percussive
drilling with conventional drill booms.
The cooling of the drill bit and flushing
of the cuttings take place inside the
GRP tube.

DYWI® Inject Packer and Accessories
■■ Mechanical packers for grouting
structures are anchored in the
borehole by screwing, firmly pressing
the fabric reinforced rubber sleeves to
the borehole wall
■■ This procedure ensures that the
packer remains in the borehole even
at high injection pressures. Smaller
deviations in terms of borehole
shapes or borehole diameters are
compensated to prevent material from
emerging out of the borehole
■■ Inflatable packers for deep boreholes
automatically tension in the
borehole at an opening pressure of
approximately 30-40 [bar]

Introduction
The DYWI® Seal Waterproofing System
is a needle-punched non-woven
impregnated membrane. The membrane
structure comprises water absorbing
and water swelling polymers.
An optional one-side polyethylene film on
top of the needle-punched non-woven
membrane and the self-healing properties
of the DYWI® Seal Waterproofing System
ensure optimum performance for various
water sealing applications.
Bentonite mats, also referred to as
geosynthetic clay liners (GCL’s), are
geosynthetic barriers used for various
sealing and waterproofing applications in
underground Mining and Civil Engineering.
DYWI® Seal Bentonite Mats are a
composite consisting of two layers of
geo-textiles filled with sodium bentonite.
The application range of
DYWI® Seal Bentonite Mats comprises
waterproofing, gas sealing, and usage
as a vapor barrier. Bentonite mats are
a proven and versatile sealing system
that has been used in many construction
projects around the world.

OMEGA-BOLT® High-Pressure Pump
Introduction
OMEGA-BOLT® Expandable Rock Bolts
are preferably installed using the
electrical type 300E high-pressure pump.
This compact high-performance pump
with an 11 [kW] electric motor is designed
for a maximum working pressure of
300 [bar].
The maximum inflation pressure is
adjusted by a spring pressure gauge;
additionally, a pressure limiting valve
prevents overload. The regulation is
effected by a combination switch on/off
and emergency shutdown, respectively.
Protection against dry running ensures a
secure operation of the low-noise and
low-vibration high-pressure aggregate.
Main Advantages
■■ Tough design and easy handling
■■ Fast installation due to high pump
performance
■■ An optimum expansion of the
OMEGA-BOLT® Expandable
Friction Bolt is ensured

High-Pressure Pump Type 300E
After insertion of the OMEGA-BOLT® Expandable Rock Bolt into the borehole, the
setting arm is fitted to the bolt’s head. By operating the valve lever on the setting
arm, the bolt is hydraulically expanded (unfolded) using high-pressure water, which is
induced into the inside of the folded bolt tube. After reaching the defined maximum
setting pressure, the valve lever is released and the setting head is pulled away from
the bolt’s head.

Cement Grout
Introduction
In engineering and underground
construction, cement grout is required
for establishing a force and form fit bond
between a supporting member and the
foundation soil or rock mass.
Depending on the application or the
supporting member type, cement
grout is applied either before or after
the installation using an injection hose.
Mixing and transport of cement grout are
carried out using mortar-mixing pumps,
which are constructed specifically for
the requirements in the construction
industry.
In contrast to customary products, cement
grout features both an excellent overhead
workability as well as early strength.
