Anchor for lightweight mast carrying overhead cable - has screw rod anchor with socket for holding the mast

摘要

The mast has a foundation which includes a screw threaded pile. This foundation is used especially for lightweight masts used for overhead cables. The starting hole (2) diameter is made greater than that of the anchor head socket (2) and this hole is filled with liquid cement mortar (3). Subsequently a screw anchor (4) is screwed into the ground and another similar anchor section (8) is joined on top of this one. On top of the anchor arrangement is connected a rod with the socket for holding the base of the mast. The sections in the ground are connected with screw sleeves (7). The concrete is compacted by the insertion of the section and concrete slurry is carried into the soil by the rotating anchor.
