What is the Horizontal urger boring?

Since the conventional micro tunneling method by pipe jacking has been proven to be too costly for the construction of small diameter and short length tunnels, the Auger Boring method has been developed in recent years as a simple and easy-to-use trenchless alternative.

The Auger Boring Technique consists is a three-step method. At the first stage, a pilot hole is bored to define the tunnel alignment, after this the pusher /cutter head and screw ushers are jaked through the pilot hole, reaming it to the muck out. Finally, the tunnel lining pipes are pushed through in the last step.  The Auger Boring Method is suitable for Connecting sewer tunnels that comprise a short distance of up to 100m in length and soil with SPT ( standard penetration test ) value N <30.
