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.

Abstract: A method for installing an underground pipe using a ground piercing tool comprises the steps of: fitting an expander onto a front nose of the tool, securing the pipe to the expander so that the ground piercing tool is disposed inside of the pipe, operating the tool in forward mode over a run to pull the pipe into the ground, removing the ground piercing tool from the expander and pipe by moving it in a rearward direction through the newly installed pipe, and leaving the expander in the ground, preferably to form the front end of the newly installed pipe. It is not required that each of the foregoing steps be conducted in the order recited. For example, the expander could be secured to the pipe after which the expander and pipe could be fitted over the tool.

Abstract: An apparatus for cleaning a culvert includes a rod pushing and pulling machine, a rod string made from a series of extension rods coupled end to end, which rod string is mounted at a proximal end to the rod pushing and pulling machine. A debris removal tool is mounted on a distal end of the rod string. The debris removal tool may comprises a rod having a center longitudinal axis, a proximal end, and a distal end, the rod having a coupling at its proximal end. A bucket is mounted at the distal end of the rod, which bucket has an end opening positioned so that movement of the bucket along the culvert scoops debris into the bucket.

Abstract: A tool for cleaning a drainage structure comprises a rod having a center longitudinal axis, a barrel housing having a proximal opening and a distal opening, the barrel housing having a center longitudinal axis and coupled coaxially to the rod, the barrel housing having an outside dimension that can be accommodated within the drainage structure, the distal opening of the barrel housing having a sinusoidal tearing contour. The tool further comprises a plurality of cutting implements radially coupled to and between the rod and the barrel housing, the cutting implements having a distal cutting edge and being angularly oriented to facilitate sweeping debris in a selected direction, and the barrel housing and cutting implements operable to rotate about the center longitudinal axis of the rod to dislodge and loosen debris inside the drainage structure.

Abstract: A tool for cleaning a culvert comprises a rod having a center longitudinal axis, a housing having a center longitudinal axis and coupled coaxially to the rod, the housing having an interior chamber, the housing has an outside dimension that can be accommodated within the culvert, and at least one paddle operable to rotate about the center longitudinal axis of the rod inside the interior chamber of the housing, the at least one paddle operable to dislodge and loosen debris inside the culvert.
