ASSEMBLY METHOD OF SUBSURFACE ANODIC GROUND WIRE, QUICKLY ASSEMBLED DEVICE FOR ITS IMPLEMENTATION; GROUND WIRE ELECTRODE Russian patent published in 2013 - IPC C23F13/08 

FIELD: metallurgy.

SUBSTANCE: method involves garland assembly of electrodes by means of connection devices, filling of the space between electrodes; mating surfaces of parts of connection device are fixed on threaded ends of electrodes, coated with a layer of current-conducting paste, joint to a fixed coupling by supply of compressed air to the connection device, the external surfaces of which are coated with mastic layer, adhesive tape is wound in 2-3 layers, and closed with cylindrical form with assembly foam. Ground wire includes a garland of electrodes assembled by means of connection devices; at that, connection device includes a coupling, a collet with an expanding head, which are fixed on threaded ends of mating electrodes, a puncheon with a piston and a cone, which is retained in initial position with a shear membrane in a pneumatic chamber, a threaded lock, and a compressed air or gas source. Electrode includes a central bar, a protective cover concentric to it, side bars welded to the central one; at that, cover is formed with a layer of activating agent of cylindrical shape, and side bars envelope the central bar within angle β of not less than 30°.

EFFECT: simpler assembly; higher labour productivity.
