Guided Boring Machine (GBM) Systems

Guided Boring Systems Akkerman began manufacturing Guided Boring Machine (GBM) systems in 2001 Using pilot tubes, our method installs 4-48” (102 – 1,219 mm) OD pipe with grade and alignment precision A GBM system combines the spoil removal process of the auger boring machine with the accuracy of a microtunneling system in various ground conditions for gravity flow installations Equipment systems feature lots of versatility with many accessory options to maximize the customer’s investment Systems can be quickly set-up and moved for the next drive Installs: reinforced concrete, steel casing, fiberglass,...

Guided Boring Systems

Akkerman GBM Jacking Frames offer unmatched versatility and advanced engineering GBM Model Max. PipeOD Min. Shaft Frame Type

Every jacking frame needs hydraulic power, Akkerman Power Packs provide the right match Pump Unit Model Power Level Hyd. Pumps

GBM Guidance System The theodolite based guidance system provides extremely accurate line and grade installations of ¼” (6 mm) at unprecedented drive lengths

GBM Pilot Tubes Akkerman’s unique dual-walled pilot tubes allow liquid lubrication to be distributed throughout installation, thus minimizing jacking forces and rotational torque for expedited pilot tube installation

GBM Eliminator The eliminator cutter head is used in nondisplaceable soils, in a two-step method, eliminating the pilot tube step The 16” (406 mm) OD cutter head features conical bullet bits and jetting nozzles to increase cutting performance Hollow augers and casing are paired with this unit for the guidance system’s line of sight to the target The eliminator works with all sizes of GBM jacking frames

The Powered Cutter Head (PCH) is an upsizing tool for a variety of ground conditions Frame Type

The Powered Reaming Head (PRH) kit is a hydraulically-driven, upsizing tool that can install 14-20” (350-500 mm) OD final product pipe The PRH allows customers to bore multiple pipe diameters with 11” (279 mm) casings and augers

GBM Accessories – Cutter Head The cutter head with integral swivel is an upsizing tool used between the pilot tube adapter and lead casing for hard ground conditions The bearing swivel allows the pilot tubes to remain stationary while the cutting teeth rotate through the ground

GBM Accessories – Auger Boring Guiding an auger boring rig with a GBM jacking frame and pilot tubes results in: improved accuracy longer drive potential smaller casing diameters faster installations ability to find hidden obstacles

GBM Accessories – Auger Boring Weld-on reaming heads are available from 12-72” (305-1,829 mm) OD to match steel casing pipe diameter A pilot guide rod swivel is used in place of a weld-on reaming head to reduce thrust at the face of the bore The universal auger bore rig adapter fits 30-72” (762-1,829 mm) auger bore rig track

GBM vs. Slurry Microtunneling Guided Boring Machine (GBM) Slurry Microtunneling The GBM system offers a low cost of operation, a small work area and minimal crew training, can use pilot tubes for obstacle detection Slurry microtunneling requires a higher initial investment, experienced crew is necessary, use is diameter dependent, water tight shaft with pit seals Diameter Range Guidance System Active, laser Minimum Shaft Size Auger/dirt bucket system Spoil Management Slurry separation equipment Displaceable with pilot tubes, nondisplaceable with use of eliminator tooling, non-pressurized soils...

Tunnel Boring Machine (TBMs) & Excavator Shield Systems

TBMs & Excavators Akkerman began manufacturing tunnel boring and excavator shield systems in 1973 Diameters from 48-168” OD (1.2-4.3 m) Ideal in ground conditions where personnel entry is permitted Both systems are passive laser guided and manually controlled for accuracy TBMs have a rotating drum and feature interchangeable cutter heads for various soil conditions Excavator shields extract spoil with a digging type machine Both systems use conveyors and haul units for spoil removal Installs: reinforced concrete, steel casing, fiberglass, centrifugally cast fiberglass reinforced polymer mortar,...

Pipe Jacking Options

TBM TBMs direct install pipe from 48-114” (1,219 – 2,896 mm) OD The system is laser guided with a selfleveling, passive laser and steering joints to ensure line and grade accuracy for gravity flow installations TBMs have interchangeable cutter heads for various soil conditions with a rotating drum An optional closed face cutter face is available for unstable ground conditions An optional mixed face cutter face is available for non-displaceable spoils for the Series II TBMs

Excavator Shields Excavator Shields install pipes from 100-168” OD (2,540 – 4,267 mm) Spoils are excavated with a backhoe type excavator Differs from the TBM in that they do not have a cutter head or rotating drum Used for traditional pipe jacking, liner plate and ring-beam and lagging installations Hydraulically powered and features a passive laser guidance system The operator controls the excavator’s movement with a joystick and foot controls while mindful of the grade
