Underground Pneumatic Boring

Pneumatic Boring

The tool uses air to pound its way through the ground underneath the obstruction. The tools is cylindrical in shape and ranges from two to five inches in diameter and between three and six feet long.  Compressed air is used to power the tool, The tool works in a way very similar to a jack hammer, inside the cylinder is a piston a valve opens and the air blows into the chamber forcing the piston forward which in turn propels the tool forward. The valve then shuts and the piston is pushed at a slower speed back in the tool, the valve reopens the piston pounds again and the tools moves forward. This process is continually repeated until the bore has run the intended distance. Both the lighter reverse hit of the piston and the friction of the ground surrounding the tool keep it moving forward instead of stopping. The speed of the tool can be controlled by a valve that connects the tools hose to the air supply this valve is outside the tool and remains accessible to the operator. As the tool pounds through the ground it compresses the soil this compaction maintains the same diameter as the tool and leaves the bore hole through which the product is passed .Applications:
