HDD is a steerable tunneling method and is a two-stage process i.e. the pilot bore and the back reaming process, and can be used for small and large diameter pipelines. The. . HAB utilizes a casing system fitted with a cutting head and rotating auger that is jacked into the earth from the launching shaft. As the auger proceeds, it transmits torque to the cutting head. The soil cuttings generated from the cutting head are transmitted back. . Pipe ramming is carried out by using a percussive hammer attached to the end of the pipe or casing that pushes it into the soil. The leading. . Also known as the compression method, the installation is carried out by pushing or pulling the pipe through the borehole created by a mole. The mole is a streamlined tool in. [pdf]
