Method for Assembling Decreasing Section Concrete Towers for Wind Turbines and Associated Wind Turbines

摘要

The present invention relates to a method for assembling concrete towers with a decreasing sector for wind turbines which comprises a phase of pre-assembly of concrete tower sections which allows to reduce the space required during the stage of pre-assembly of the different tower section prior to lifting and the civil work associated to set said space up wherein, during the pre-assembly phase, a first annular section is confined at least partially within the inner space defined by a second annular section, the invention also relating to the wind turbine associated to said method of assembly.

1. Method for assembling decreasing section concrete towers for wind turbines which comprises:
a pre-assembly phase of concrete tower sections,
wherein the tower comprises at least two stackable annular sections, a first stackable annular section and a second stackable annular section with a greater section than the first stackable annular section, wherein the stackable annular sections comprise in turn at least two precast concrete segments and, wherein the pre-assembly phase is carried out in at least one pre-assembly zone near to the base of the tower and comprises stages of joining the at least two precast concrete segments of a stackable annular section carried out for at least the first stackable annular section and the second stackable annular section, and wherein during the pre-assembly phase the at least two precast concrete segments of the first stackable annular section are confined at least partially within the inner space defined by the at least two precast concrete segments of the second stackable annular section.
