ABSTRACT This invention relates to a method and a device for installing a ground wire in the ground. Conventional ground wires often consist of copper-plated steel tube sections, which are successively driven into the ground and jointed, whereby a great number of joints are obtained which reduce the conductivity of the ground wire assembly. Moreover, during the driving oper- ation, the copper plating of the steel tube sections is also subject to damage. In the present invention, the ground wire is provided in the form of a coherent metal wire of copper or the like and is installed by means of a driven member, which is con- nected to the lower end of the wire and is driven through a succession of driven extension elements. The device is installed in the ground with the wire running along the outside of the extensions. In this manner, a continuous ground wire of high, uninterrupted conductivity is obtained, whilst preserving the advantages of relatively simple installation through the medium of a rigid driven system.
