GUIDED BORING SYSTEMS

The Akkerman Guided Boring Machine (GBM) system
offers customers accurate and extended drive lengths
in various ground conditions for 4-48-in. (102 - 1,219
mm) OD pipe installations. The GBM provides the spoil
removal process of the auger boring machine and the
same level of accuracy as traditional microtunneling—
all in one compact, multifaceted system. The pipe
installation involves a multi-step process where launch
and reception shafts are strategically located to minimize
surface disruption using pilot tubes, casing and augers
and ancillary tooling in advance of the pipe. Our complete
line-up of GBM jacking frames, power packs, increase
tooling and ancillary equipment provides contractors
with the versatility they need for a wide range of soil
conditions, pipe diameters and project applications.

GUIDED BORING SYSTEMS | GBM GUIDANCE SYSTEM

The GBM Guidance System provides line and grade accuracy for the GBM system to within a ¼-in. (6 mm) at 400-
ft. (122 m). During operation, an LED target is placed in the lead pilot tube’s steering head. The theodolite’s
cross hairs are aligned to the drive’s line and grade and the camera relays this data to the computer-controlled
digital monitor, mounted to the GBM jacking frame. The operator assesses the target’s position from the
monitor and makes line and grade adjustments as necessary. The Guidance System assembly consists of
a theodolite with remote focus, illuminated LED target, camera, computer-controlled digital monitor, lateral
slide and elevator column assemblies, counterweight, alignment holder, bore sight laser and protective cases.

GUIDED BORING SYSTEMS | PIPE INCREASE TOOLING

Powered Cutter Heads (PCHs) increase the bore to match the pipe diameter and features two independent hydraulic
drive systems for the cutter bit and augers for conveying soil to the reception shaft. Lubrication sources for the cutter bit
and exterior of the pipe, work together to reduce jacking forces and increase advancement rates. Standard PCHs are avail-
able in sizes 20-44-in. (508-1,118 mm) OD with increase kits for 22.5-48-in. (572-1,219 mm) OD. The Powered Reaming
Head (PRH) Kit includes a base unit of 14 or 30-in. (356 or 762 mm) OD with increase kits to up-size to 20 or 48-in. (508
or 1,219 mm) OD. The PRH increases the bore diameter and reverses the augers and casing to force soil to the reception
shaft. The 16-in. (406 mm) Eliminator is used in non-displaceable soil in a two-step process to perform guided boring
without the use of pilot tubes and coupled with hollow center augers for target site path. The Cutter Head Integral Swivel
matches an 11 or 16-in. (279, 406 mm) pipe diameter, and is applicable for ground conditions above 35 blow count. It is
placed in front of the lead casing and auger and functions to keep the pilot tubes stationary while the cutter bit rotates.

GUIDED BORING SYSTEMS | GUIDED AUGER BORING TOOLING

The Universal Auger Bore Rig Adapter includes mounting hardware to connect the GBM 240A jacking frame to auger bore
rigs with rail widths from 33-60-in. (838-1,524 mm). Weld-On Reaming Heads (WORHs) up-size the bore in single and
two stages, and feature arms that are flush with the ID of the steeling casing to allow soil to be removed from the pipeline
with the auger bore rig. WORHs up-size from the pilot tube adapter to steel casing in one or two steps from 12-72-in. (305-
1,829 mm) OD. The Pilot Tube Guide Rod Swivel is used in-between the pilot tubes and the cutter bit/auger for ground
conditions too hard to advance a WORH. The Pilot Tube Guided Rod Swivel connects with a 3-in. (76 mm) hex core, and
functions to guide the cutter bit/auger on line and grade of the pilot tube’s course while preventing rotation of the pilot tubes.

valve on the tank’s outlets. The compact 1325G Pilot Tube Lubrication Pump provides a lubrication source during the pilot
tube and guided auger boring operations. The 1325G offers enough fluid capacity for an average 400-ft. (122 m) bore and can
be filled with liquid based polymers to supply lubrication to the pilot tube string or with water for pressure cleaning operations.

MICROTUNNELING SYSTEMS

Microtunnel Boring Machines (MTBMs) install gravity
flow pipelines requiring precise line and grade in
poor soil. Microtunneling is a non-manned, remote
controlled, continuously supported pipe jacking method.
Standard MTBMs are sized in the 30-96-in. (762-2,438
mm) OD range. Soil excavation takes place by way
of infusing the soil with slurry at the face of the bore
where cuttings are forced into slurry inlet holes in the
MTBMs crushing cone for circulation to and from a
separation plant through a closed system. A complete
slurry microtunneling system is comprised of a pipe
specific MTBM, control container, remote hydraulic
power pack, jacking frame, a series of pumps, laser,
water cooling tank, slurry trunk and additional lines, and
a slurry separation plant. The launch shaft is outfitted
with a pit seal to prevent flooding of the shaft and a
project specific thrust block to distribute jacking force.
Microtunneling operations are managed by an operator in
an above ground control container alongside of the shaft.

MICROTUNNELING SYSTEMS | MICROTUNNEL BORING MACHINES

Microtunnel Boring Machines (MTBMs) in standard sizes of 30-96-in. (762-2,438 mm) OD, accurately install
pipe in virtually any ground condition, especially in high levels of ground water. MTBMs feature high pressure
jetting nozzles, an articulated steering joint with three-point steering control, and hydraulically activated dirt
wings to minimize MTBM roll. The guidance system relays all critical operation data to the control container using
a proprietary Akkerman Machine Control Software Program. Additional MTBM attributes include a live, one-way
audio system and camera allowing for system monitoring during operation, gas detector and submersible pump.
Standard MTBMs can be outfitted with increase kits for adaptability. The soft ground and mixed ground cutter
heads and crushing cones are hard faced to withstand wear and can be customized for specific ground conditions.

PIPE JACKING & TUNNELING SYSTEMS

Tunnel Boring Machines (TBMs) and Boring Shields (BSs)
are used to install 48-93-in. (1,219-2,362 mm) and 96-
168-in. (2,438-4,267 mm) OD jacking pipe. Both systems
are interiorly controlled by an operator. TBMs excavate
soil at the face of the bore when hydraulic motors
rotate the inner drum; the cutter head excavates and
soil is transported via conveyor and haul unit system for
disposal in the launch shaft. The BS system excavates
soil with a backhoe-type excavator at the face of the
bore and is removed in the same manner as the TBMs.
With both systems, a passive pipe laser in the launch
shaft projects a laser point on the cutter face for the
operator to monitor and make steering corrections as
necessary. The all-in-one Tunnel Boring System easily
adapts to any jacking pipe with an appropriately sized
TBM, yoke and skid section(s). A complete all-in-one
Tunnel Boring System is comprised of a TBM, pump unit,
yoke, skid, haul unit, conveyors, a pipe laser and often
a bentonite pump. A Boring Shield (BS) system contains
a boring shield with excavator, conveyors, haul unit,
power pack or pump unit, pipe laser and jacking frame.

PIPE JACKING SYSTEMS | TUNNEL BORING MACHINES

Tunnel Boring Machines (TBMs) range in common pipe diameters from 48-93-in. (1,219-2,362 mm) and are suitable
for standard pipe jacking applications. The Series II TBM has a sealed steering joint that allows for bidirectional, full
articulation at the face of the bore. The operator controls steering, maintains line and grade and monitors the spoil
removal process from an interior control station. As soil is excavated, dirt paddles propel it onto the belt or screw conveyor
for transport to the haul unit. TBMs are equipped with a bi-directional, open-face or custom configuration cutter head.

The 5200 Pump Unit, a component of the all-in-one Tunnel Boring System, is positioned behind a skid section and
yoke in the launch shaft. The operator, safely located on the pump unit’s platform, engages controls to extend jacking
cylinders to advance the yoke and TBM and pipe along the skid base. The 5200 Series Pump Unit features independent
hydraulic jacking and TBM supply functions with pressure compensated capabilities. Various configurations of 30, 60,
90 and 120 GPM (L/min) are selected to match boring head and auxiliary requirements. Skid Base Sections allow
for various shaft configurations with the Tunnel Boring System. Thrust Yokes match the pipe diameter and provide
a 360-degree surface to minimize point pressure on the pipe and transfer thrust from the pump unit to the pipe.

PIPE JACKING ACCESSORIES | PIPE JACKING AND MICROTUNNELING ACCESSORIES

Keyhole Jacking Frames offer a high capacity jacking frame from a 16-24-ft. (4.87–7.3 m) shaft. They
feature 800-1,200 tons (726-1,089 mt) of thrust capacity to advance pipe with a maximum 102-in. (2,591
mm) OD in 10-ft. (3 m) lengths. Smaller pipe can be used with a thrust adapter. Keyhole jacking frames are
configured with and without a dirt bucket bay for pipe jacking and microtunneling applications. Keyed blocks
on the hydraulic jacking cylinders continuously advance the MTBM or TBM and a winch is used to retract the
cylinders. The EH2250 Bentonite Pump is used to lubricate pipe to ease thrust loads when jacking pipe.

PIPE JACKING ACCESSORIES | PIPE JACKING AND MICROTUNNELING ACCESSORIES

The electric P600 Power Pack powers the keyhole jacking frame and is operated with an in-shaft pendant. The P600
features a 600 gallon (2,271 L) hydraulic reservoir with three interchangeable pump and motor modules in high and
low pressure configurations. Belt and Screw Conveyors transport soil from the face of the bore to the dirt bucket.
Haul Units are positioned on track in the tunnel, and an operator engages the unit to transport the full dirt bucket
from the back of the conveyor to the launch shaft for disposal. Haul units are electrically powered with a removable
battery pack and equipped with disc brakes. Dirt Buckets are sized to match TBM and haul units to most efficiently
transport soil during the pipe jacking. Intermediate Jacking Stations (IJSs) distribute thrust load to facilitate
longer drives. IJSs are encased in a steel housing that is non-recoverable. The Laser Stand is positioned behind
the pump unit and cradles the pipe laser at the correct height for sight-down the tunnel onto the TBM or BS head.

EARTH PRESSURE BALANCE SYSTEMS

Earth Pressure Balance Machine (EPBMs) Systems
install pipe by pipe jacking or segment erecting methods.
EPBMs excavate soil while balancing machine and soil
pressures to minimize ground settlement. With both
methods, soil from the EPBM cutter chamber is injected
with foam and slurry to balance the face pressure
then removed through screw conveyors and a haul unit
system. The operator guides the EPBM and monitors
targeting data, pressures, position, speed, torque and
flow from a control console to pilot an accurate course
and achieve maximum productivity rates. A series of
back-up cars follow along behind the EPBM, each with
a special function. A power container distributes power
to EPBM operations and foam and slurry plants provide
additives which aid in soil removal. The EPBM cutter
head design and power source can be configured to
best meet geological and performance requirements.

EARTH PRESSURE BALANCE SYSTEMS

Earth Pressure Balance Machine (EPBM) systems are complex in design and performance and are
custom built to suit project parameters. EPBMs are capable of curves and extended lengths with extreme
accuracy using a specialized guidance system. The Pipe Jacking EPBM and pipe sections are advanced
by a hydraulic jacking frame in the launch shaft. The Segment Erecting EPBM positions segments to form
a ring to build the tunnel. The EPBM advances itself off the previously built ring with hydraulic cylinders.
