摘要

On the periphery of the support unit (3) are several equally spaced brushes (1,2). Each brush is rigidily fixed to the support unit at its upper end, and projects freely outwards towards the ground surface. The brushes are formed of strong steel wire (9) enclosed in a steel wire-reinforced rubber casing (10). At their lower end, the steel wires extend out of the rubber casing to an extent the length of which corresponds to the depth of intended penetration into the earth surface.
