Guided Auger Boring

Guided Auger Boring is a process used for the accurate trenchless installation of clay or concrete sewers.

The method involves creating a pilot bore between launch and reception pits by pushing a series of hollow rods behind a drill head. The drill head is kept on target by monitoring it's alignment through the hollow rods using digital camera equipment.

On completion of the bore, a series of temporary steel casings containing auger flights are pipe jacked along the the path of the rods to excavate the soil and create a tunnel. The helical augers transfer spoil backwards into the launch pit where it is removed.

When the tunnel is complete, the auger flights are removed from the casings. The casing can be left in place to form a duct. Clay or concrete pipes are then jacked from the launch pit, simultaneously displacing the steel casings into the reception pit, until the pipeline is complete.

A.E. Yates operate an advanced guided-auger system capable of installing pipes to sewer tolerances.
