CONSTRUCTION APPARATUS FOR OFFSHORE WIND-POWER GENERATION TOWER AND CONSTRUCTION METHOD THEREOF

摘要

The present invention relates to a construction apparatus for an offshore wind-power generation tower and a construction method thereof. More specifically, the present invention relates to an apparatus for constructing an offshore wind-power generation tower, comprising: a tower formed by installing a plurality of columns in multiple stages, wherein lower and upper columns adjacent to each other, among the columns, are coupled at the upper end and the lower end thereof, respectively; a retractable cylinder standing inside the lower column; a lower-column coupling means for coupling and releasing the lower portion of the cylinder and the lower column; an upper-column coupling means for coupling and releasing the upper portion of the cylinder and the upper column; and a column coupling means for coupling and releasing the upper column and the lower column, and a construction method thereof. Therefore, the present invention does not use lifting equipment equipped with a large crane, thereby solving difficulty in construction, and reducing construction cost and time.
