The costs of this operation are orders of magnitude cheaper than microtunneling or directional drilling. As mentioned, no drilling fluids are used other than for lubricating the pipe casings and auger, therefore, reducing the potential impact on surrounding soil.
As the casing is installed at the same time as the auger operation continues, the surrounding soil is held in place by the casing and there is limited opportunity for soil collapse or damage to roads, rail tracks on the surface.
Although the directional steering is limited, the grade of the bore can be accurately set through the alignment of the equipment in the entrance pit. The operation of the horizontal auger boring machine is relatively simple compared to more technological trenchless methods.
This means that less training is required, and the system can be used in developing countries where skilled resources aren't easily available.
Some of the disadvantages of there is very limited ability to steer a horizontal auger boring machine, hence the alignment in the entrance pit is critical to ensure the correct path to the desired exit. Also, horizontal auger boring is not suitable for wet running ground or ground where there is a high frequency of boulders.
Horizontal auger boring is one of the oldest and most successful methods of trenchless construction. Although some newer technologies offer specific advantages in certain ground conditions and in steering ability, horizontal auger boring remains a low cost and highly effective method for many applications.
As this technology continues to advance and improvements made to the steering ability of auger machines, the auger boring machine will remain one of the common methods of trenchless construction for the foreseeable future.
