Abstract:
1. A process for producing precast concrete pylon wall segments for a wind power installation pylon, each concrete pylon wall segment having a first end and a second end opposite the first end, the process comprising: casting concrete into a casting mold that has a planar floor to produce a concrete pylon wall segment having a planar underside at the first end; hardening the concrete to a predetermined minimum strength to obtain a precast concrete part having the predetermined minimum strength; applying an equalization layer to a join surface at the second end of the precast concrete pylon wall segment that is opposite to the planar underside of the precast concrete pylon wall segment at the first end; placing the precast concrete pylon wall segment of predetermined minimum strength on a horizontal plane; and removing at least a portion of the equalization layer on the second end of the concrete pylon wall segment until the second end of the concrete pylon wall segment is plane-parallel to the first end so that the first and second ends of the concrete pylon wall segment are plane-parallel to each other.
