Abstract
A device configured to bore out a section of underground pipe or an interior liner therein without the need to dig out the section of pipe can include a plurality of arms extending radially outwardly from a central shaft. The central shaft can be configured to attach to a tool or a robot. The device can also at least one cutting device extending radially outwardly from the central shaft. The at least one cutting device can be configured to move in unison with the central shaft. rotation of the central shaft can cause the at least one cutting device to contact and cut an interior surface of the underground pipe or the interior liner thereof.
Claims20
A device configured to cut or bore out underground pipe or an interior liner thereof, the device comprising:
- a central shaft having a proximal end, an opposing distal end, and a central axis extending therebetween, the central axis being configured to extend along a longitudinal axis of at least a section of an underground pipe or an interior liner thereof, the proximal end of the central shaft being attachable to a tool or robot, the central shaft being configured to be rotated by the tool or robot around the central axis thereof;
- a plurality of arms extending radially outwardly from the central shaft, each of the plurality of arms between positioned along the central shaft between the proximal and distal ends thereof;
- and
- at least one cutting device extending radially outwardly from the distal end of the central shaft, the at least one cutting device being configured to rotate with the central shaft, rotation of the central shaft causing the at least one cutting device to contact and cut an interior surface of the underground pipe or the interior liner thereof.
A method of reducing or removing one or more lifts from an interior liner of a section of underground pipe, the method comprising:
- inserting a device into the interior liner of the underground pipe, a proximal end of a central shaft of the device being attached to a tool or robot configured to rotate the central shaft about its central axis;
- aligning the central shaft of the device with a longitudinal axis of the underground pipe;
- and
- causing the tool or robot to rotate the central shaft, thereby causing at least one blade attached to or near a distal end of the central shaft to rotate within the underground pipe or the interior liner thereof to reduce or remove one or more lifts.
