Over 400,000 linear feet of NO-DIG pipe has been installed on more than two hundred projects in the U.S. since 1992.
Install the pilot tube precisely on
line and grade. The existing soil is
displaced during advancement of the
pilot tube. The hollow stem of the tube provides an optical path for the theodolite and camera to display the head position and steering orientation on a monitor screen.
Follow the guided path of the pilot
tube with a reaming head and auger
casings. The displaced soil around the
pilot tube enters the reaming head and
is transported to the jacking shaft for
removal via auger casings. As the auger casings are installed, the pilot tubes are advanced into the reception shaft for removal.
Install the NO-DIG Pipe once the
reaming head reaches the reception
shaft. The reaming head and auger
casings are advanced into the reception shaft by the NO-DIG pipe and removed.
The completed result is a pipeline installation with the same guided accuracy as the
