HORIZONTAL AUGER BORING
Horizontal Augering is a steerable, trenchless method which uses a small excavation to install a variety of pipes, conduits and cables underground. From utility installation to fluid movement to flood abatement, this method is used to minimize traffic disruption, ground disturbance, & environmental impact. This is extremely important in areas of high population density, existing utility installations, and sensitive environmental areas.
- There are 4 main equipment components in an auger boring operation; the rotating cutting head, the auger, jacking equipment and entrance and exit pits.
- The rotating cutting head cuts through the ground at the bore face at the front casing. The cutting head normally sits just in front of or just inside the casing. As spoil is created through the cutting action, it falls into the casing onto the auger, which is a rotating screw with helical fluted coils. It is located inside the pipe casing.
- As the auger rotates, the spoil is drawn along the coils towards the entrance pit where it is removed. Spoil can be removed from the entrance pit via a conveyer, manually or with mechanical equipment.
