The device of the terrain, which is soluble in the investigation of sub - surface electrical prospecting

摘要

A leaktight sleeve ribbon 10 is made of two strips of a polyurethane-impregnated glass fabric, which houses in its central zone a sheet of conductors 11. Leaktight conducting crosspieces 12 are mounted substantially evenly spaced along the length of the sleeve ribbon 10. They may receive various types of ground electrodes. The conductors 11 extend to one end 101 of the ribbon, which may be wound on a drum 13. Switching means are housed inside this drum which allow any desired configuration of the electrodes in quadrupole to be produced for electrical subsurface prospecting. IMAGE
