Since inception, Akkerman has grown with the evolution of industry demands. We offer pipe jacking, microtunneling, guided boring and earth pressure balance systems to address each project’s ground conditions, pipe specifications and complexities. Our equipment matches pipe diameters from 4-inches (102 mm) through 14-feet (4.3 m) in numerous lengths. When we present equipment solutions, we include everything you need to tackle the whole project including: power systems, spoil removal, pipe increase tooling, and storage and versatility packages to keep your equipment relevant to industry requisites project after project.
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. >> more
Microtunnel Boring Machines (MTBMs) install gravity flow pipelines that require precise line and grade in poor soil. Microtunneling is a remote controlled, continuously supported pipe jacking method. Standard center drive and face access, peripheral drive MTBMs are sized in the 30-114-in. (762-2,896 mm) OD range. Soil excavation takes place by infusing the soil with slurry at the face of the bore and cuttings are forced into slurry inlet holes in the MTBM’s crushing cone for circulation to and from a separation plant through a closed system. >> more
Tunnel Boring Machines (TBMs) and Boring Shields 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 for disposal from the launch shaft. The Boring Shield system excavates soil with a backhoe-type excavator at the face of the bore and is removed in the same manner as the TBMs. >> more
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. >> more
