PURPOSE:To easily bury the title difficulty soluble galvanic electrode by using an assembling structure spiral-provided tubular hand auger as the housing tube, burying a difficulty soluble electrode in the tube, and packing a backfill in the tube. CONSTITUTION:A soil crushing bit 14 is provided at the front drill part 13 of the spiral-provided tubular hand auger 11, a backfill 15 is packed in the tube, and a difficulty soluble electrode 16 having a terminal device 17 is buried in the backfill 15. A lead wire 19 is connected to the base end of the electrode 16 through a lead wire connection 18. The ground surface is bored by this structure, the electrode-contg. auger 11 is set in the hole, rotation is provided while connecting a joint pipe 21 with a joint 20, and the auger is moved up and down and driven. When the auger reaches a specified depth at which the electrode is set, boring is stopped, and the lead wire 19 is connected to the external power source device. Consequently, the difficultly soluble electrode 16 can be set without being disturbed by the environment, site, etc. |
