ABSTRACT:
The invention relates to a tool for preventing the vortex effect, comprising three corrugated tubes which extend helically from the upper end (2) of the tower (3), such as to cover only the upper part thereof. The helix pitch defined by the corrugated tube (1) along the length of the tower (3) is fixed using cords (5) which are attached at each revolution of the tube. The corrugated tube (1) is lifted with a cathead (6) which is disposed on the structure that is used to anchor (4) the tool to the tower (3), the structure comprising three T-shaped sections which form an X having sectors (9) fixed to the ends thereof. In addition, four legs (14) are welded to the aforementioned sectors and the tubes are wound around said legs.
