Pipe slitting apparatus
An apparatus for replacing an existing pipe. The apparatus comprises a slitter and expander which surround a wire rope. The wire rope is attached to the expander, and the expander abuts either the slitter or a separation tube disposed between the expander and slitter, such that the slitter and expander are pivotable relative to each other. The apparatus is placed in a pipe to be replaced and pulled. While being pulled, blades on the slitter slit the pipe, while a sloped surface of the expander moves the slit sections apart into surrounding soil. A replacement pipe may be pulled by a pipe putter attached to the expander. A beacon may also be disposed within the apparatus to emit a signal for locating the apparatus white underground.
