DEVICE OF HORIZONTAL ANODE EARTHING IN SOILS WITH HIGH ELECTRIC RESISTANCE Russian patent published in 2010 - IPC C23F13/06 

FIELD: electricity.

SUBSTANCE: device of horizontal anode earthing in soils with high electrical resistance includes trench, stands on trench bottom, electrodes of anode earthing on stands, instrumentation column, cables for connection of electrodes and instrumentation column, bentonite clayey mortar thickened to cream-like condition and used in wells drilling to coat electrodes and stands, well from surface to clayey mortar, carpet over well and gas exhaust pipes. Distance in any direction from electrodes of anode earthing filled with bentonite clayey mortar used in drilling of wells to soil with high electric resistance makes at least 0.5 m. Depth of trench is assigned provided that clayey mortar is arranged below depth of frost zone.

EFFECT: invention provides for earthing in soils with high electric resistance, possibility of dismantling and repair of earthing.
