Claim 15:
16. A method of using a hollow boring auger, the hollow boring auger including a first mounting part and a second mounting part connected one to the other and movable between an open state and a closed state enabling the first and second mounting parts to be closed around a pole, encircling the pole, wherein the first mounting part and the second mounting part form an upper portion of the hollow boring auger, the first and second mounting parts attached correspondingly to a first auger part and a second auger part forming in the closed state the hollow boring auger circling the pole and projecting downwardly from the first and second mounting parts, wherein the first auger part and the second auger part form a lower portion of the hollow boring auger, and a first semi-circular attachment plate attachable between the corresponding first mounting part and the first auger part and a second semi-circular attachment plate attachable between the corresponding second mounting part and the second auger part, and once attached the opening and closing of the first mounting part and the first auger part, and the second mounting part and the second auger part is together, so as to create jaws which can be closed about a base of the pole, wherein the upper portion of the hollow boring auger and the lower portion of the hollow boring auger are removably attached to one another by fixings via the first semi-circular attachment plate and the second semi-circular attachment plate, the method including the following steps:
a. positioning the attached first mounting part and first auger part and second mounting part and second auger part close to a base of the pole;
b. closing jaws created by the first mounting part, first auger part, and the attached second mounting part and second auger part, about the base of the pole; and
c. operating a rotation apparatus whereby the first and second auger parts rotate to create a hollow trench, about the base of the pole, wherein the rotation apparatus is housed in the first and second mounting parts, and wherein a cylindrical collar of the hollow boring auger projects upwardly from the first and second mounting parts and is configured to encircle the pole in the closed state, and wherein the collar extends at least 250 millimeters along a length of the pole, in use.
