Abstract
A soil excavating and utility pole securing sleeve is disclosed which will, when rotated around a standing utility pole, excavate an annulus of soil between the pole and the interior of the sleeve. The excavating sleeve defines an elongated hollow cylinder having teeth and inwardly bent excavating doors or flaps at one end which moves the soil between the utility pole and the sleeve out the door or flap and compacts the soil into the earth surrounding the sleeve. The sleeve is rotated into the ground around the utility pole for half its length, left there, and the evacuated annulus of soil then filled with a mixture of epoxy, resin, fungicide, and aggregate, allowed to cure and harden in order that the utility pole, the filling, and the sleeve become one single structure with a strength greater than that possessed by the original utility pole when new.
