Abstract
A method of installing an underground pipe includes a step of placing a leading end of a pipe section at an entry point for the underground pipe. An arcuate soil shoe is attached to an inside surface of the pipe section at or near the leading end of the pipe section, which soil shoe has a passageway therein with one or more outlets. A conduit is positioned to feed a lubricating liquid into the passageway, which liquid passes through the outlets to enter the inside of the pipe section. A driver such as a pneumatic impact tool is placed at a trailing end of the pipe section and used to drive the pipe section into the earth. A lubricating liquid is supplied through the conduit, which liquid passes into the passageway and through the outlets into the inside of the pipe section.
