Pilot Tube Guided Boring - Pilot Tube Method - Installation of Pilot Tubes On Line and Grade

Описание: The Pilot Tube Method (PTM) is one of the most popular and versatile techniques available to an underground contractor for the gravity flow sewer industry. Pilot tubes are first installed with a high degree of accuracy while integrating features of other trenchless technologies like microtunneling, auger boring, pipe ramming, and horizontal directional drilling to install a variety of product pipe.

The first step of the PTM method requires the accurate installation of pilot tubes. In most cases, the dual‐walled pilot tube displaces the ground while the operator makes any steering corrections through real‐time feedback of the theodolite guidance system. As the leading manufacturer of pilot tube technology, Akkerman is continually making advancements to achieve longer distances for diverse ground conditions.

With pilot tubes accurately installed across the full drive length, a series of upsizing tooling is used to match the final product pipe. The upsizing method is dependent on factors like ground conditions, product pipe, drive length, and shaft constraints.
