Introduce Lubrication Using Pilot Tube Guided Boring System and Dual Wall Pilot Tubes

Guided Auger Boring (GAB) is a popular and cost‐effective trenchless method to accurately install steel casing for underground utilities, water lines, and sanitary sewers. The method combines pinpoint accuracy with a pilot tube installation to control line and grade and the excavation process of horizontal auger boring.
During the pilot tube installation, the soil is displaced by a slant‐bill steering head while thrust and rotation pressures are monitored in the launch shaft. Monitoring pilot tube installation data allows the contractor to probe the ground for potential obstructions. At the same time, the soil’s in‐situ properties return to their natural state if a pilot tube pull‐back is necessary.
Pilot Tube lubrication plays a pivotal role in the success of the trenchless method by reducing frictional forces along the pilot tube exterior.
Akkerman produces a complete family of lubrication/mud pumps suited for the trenchless industry’s rigorous demands. High‐pressure lubrication pumps are the perfect complement to extend distances during pilot tube installations.
