Abstract

PURPOSE: To continue a regulated grounding resistance value as a grounding electrode for a long time by filling highly permeable sand while blowing out a reducing agent through a number of nozzles of the grounding electrode inserted into a vertical hole drilled in the ground. CONSTITUTION: A vertical hole 6 having prescribed depth and diameter is formed in the ground 5. A copper pipe grounding electrode 7 having a hollowed pipe form having a number of exhaust nozzles 10 bored on the circumferential wall is inserted to the center of the hole 6 until the lower end part gets close to the bottom part of the hole 6, and the upper end side is connected to the discharge side of a compressor 8 through a connecting hose 9. While a reducing agent for reducing the grounding resistance value such as sodium silicate or urea resin is pressure-injected from the exhaust nozzles 10 into the hole 6 through the electrode 7 by the pressure of the compressor 8, highly premeable sand 11 is filled from the upper side of the electrode 7 to form a homogeneous reducing agent distributed part 12 around the electrode 7. The hose 9 is then removed, and a lead wire is pressure-connected to form the grounding electrode.
