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.
