Abstract: A method of repairing a utility pole in place. The method comprises excavating soil from around the utility pole to expose a portion of the pole surface below the ground line, and adhering a plurality of prefabricated sleeve segments to the surface of the utility pole to form a circumferential sleeve. The plurality of sleeve segments are positioned to extend above and below the ground line and have side edges that each overlap an edge of an adjacent sleeve segment. The hole around the pole is then filled, such as with a slurry of soil, water and sodium silicate. This method may be beneficially used on wooden utility poles that have experienced decay, in order to restore strength to the pole.

Abstract: Placement of a conductive polymer composition grounding material at frequent points in an integrated electric transmission and distribution system to minimize transmission of harmonics and the resulting electrical losses is described.

Abstract: A conductive polymer backfill composition and method of use for setting or resetting utility poles is described. The backfill material is effective in simultaneously reinforcing and electrically grounding the utility pole.

Abstract: A method of abandoning an underground storage tank including the steps of: removing residuals, if any, from the tank and filling the tank with a mixture which includes water, sand, a binding agent and a material for promoting uniform mixing of said mixture. In one embodiment of the invention, a surfactant is added to reduce the amount of water required by the mixture.

Abstract: A method of abandoning an underground storage tank including the steps of: removing residuals, if any, from the tank; washing the tank with a detergent solution; removing the washing solution; and filling the tank with a mixture which includes water, sand, a binding agent and a material for enhancing the flowability of the mixture.

Abstract: This invention provides a method for repair for poles which have been damaged by environmental effects, which is easily transportable, simple to install, and easily adaptable to many classes of poles. The method involves excavating around the pole, cleaning the surface of the pole, pumping a fumigant into the pole, applying a bonding agent to the clean surface, and then applying strips of a composite fiberglass mat and resin to the pole in a controlled manner until a desired casement thickness has been achieved. The repair is completed by application of an ultraviolet resistant coating to the pole.

Abstract: An improvement in the known method of setting or resetting poles in the ground with foamed polyurethane resins formed in-situ from polyisocyanate and resin reactive therewith, is described. Ground water is often encountered in pole setting and affects polyurethane foam formation by undesirably reacting with polyisocyanate to give a foam of insufficient density and strength. This improvement comprises extending polyurethane components with a nonvolatile water-immiscible material (e.g. hydrocarbon oil) which inhibits the undesired reaction of water and polyisocyanate and reduces the unit cost of the polyurethane foam. The addition to the polyurethane composition of termite repellant materials and preservative agents for the pole is also described.
