Abstract (en)
The invention concerns a method for producing a concrete pillar, said method being based on the shotcreting of an appropriately shaped frame structure of the concrete pillar with concrete, and said frame structure is simultaneously rotated on a rotating shaft (2) attached to the frame structure while being shotcreted with concrete, and said shotcreted concrete surface is shaped after shotcreting with the help of, e.g., a collar (4) having a desired shape. The concrete pillar is allowed to harden while being attached to the rotating shaft (2), and after hardening, the surface of the concrete pillar is ground with a grinding apparatus (5), and the concrete pillar is rotated on its rotating shaft either in the same rotating equipment in which the concrete pillars are shotcreted, or alternatively, in a separate grinding apparatus.
