<P>PROBLEM TO BE SOLVED: To provide a grounding method using a grounding rod, which facilitates the installation of the grounding rod as well as saves the amount of a resistance reduction material. <P>SOLUTION: The grounding method comprises: a supply process for supplying a resistance reduction material S to a pre-drilled installation hole H; and an installation process for installing a grounding rod 1, formed in a long shape in one direction to be installed into the earth so as to allow a ground current to escape therein, through the bottom of the installation hole H into the earth. In the installation process, the grounding rod 1 whose surface is provided with a recess part 103 is installed into the earth in a manner that at least a part of the recess part 103 is covered with soil. When using a grounding rod 1 whose surface has a recess part 103 continuously formed in the longitudinal direction, the order of the supply process and the installation process may be reversed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
