Guided Auger Boring in Harlow, Essex

How It Works

  • The Guided Auger Boring machine is positioned between thrust walls in the launch pit and the line and grade is set.
  • Pilot rods are pushed through the ground and kept on course via a steering head, which is monitored by a theodolite camera.
  • When the steering head reaches the reception pit the pilot rods are used to keep the auger flights on course.
  • Finally, clay jacking pipes are pushed through the bore.
