A method and apparatus for lengthening or shortening a pole supporting lines, such as electric power and telephone lines. The method includes the providing of a stub adapted to be joined in abutting end-to-end relationship with the lower end of the pole to form a lower extension and support for the pole. The pole is raised vertically until its lowermost end portion is clear of the ground so that a lower end portion of the pole can be sized, as necessary, for reception by a mechanism joining the pole and stub. If necessary, the length of the pole is also shortened to provide a desired combined length. After the lower end has been sized, the pole and stub are joined to each other so that they constitute, in effect, a substantially rigid continuation of each other. The pole and stub are then vertically lowered into the ground to a required depth and the ground is consolidated around the base of the stub. The apparatus includes appropriate structure for accomplishing the preceding method.
A method of attaching a stub to a pole partially embedded in the ground, said method comprising:
A method as claimed in any one of the preceding claims wherein the stub is of a material resistant to pole-strength deterioration.
