What Does Steerable Auger Boring Mean?
Steerable auger boring is the process of trenchless construction where a product pipe is installed underground with an auger machine that has the capability of adjusting its direction to maintain the desired path through the ground. Steering can be carried out by using a pilot tube or by using a steerable head. Steerable auger boring can be used where it is important for the pipe to be laid on a defined path.
Trenchlesspedia Explains Steerable Auger Boring
Steerable auger boring controls the line and grade of the pipe being installed. This can be accomplished through a pilot tube where a small gauge pipe is bored which makes it easier to adjust when the direction is moving off the defined path. Once the pilot tube is bored, the larger diameter bore can be augered directly along the pilot tube trajectory. A steerable head, on the other hand uses hydraulic deflection panels welded to the lead pipe push against the soil thus changing the direction of the cutting head and lead pipe.
