Definition - What does Track Bore mean?
A track bore is a hole created using the track boring method of trenchless construction. The use of a track within an entrance pit offers stability and ease of movement for the boring machines when placed upon and attached to the tracks. Auger boring machines are typically mounted on track assemblies that are anchored to the ground.
Trenchlesspedia explains Track Bore
The track boring machine used in trenchless construction must be safely installed within the insertion pit. A short piece of track is laid for the boring machine. Following safety guidelines is essential. The track itself may be 10-15 feet long and 4-7 feet wide. The dimensions vary with the manufacturer. Extension tracks are available.
The machines normally associated with track boring are auger boring machines. The machine runs along a track until it completes a track length of boring. It is then returned to its starting place along the track. This process is repeated until the boring job is completed.
