Abstract
The invention in particular provides a construction method for installing an offshore wind power generation fan, solving the problems that the existing offshore wind power generation fans have high installation costs and the equipment is not easy to rent. The construction method comprises the following steps of: a. erecting support columns with connecting cross beams on a working platform; b. arranging guide columns in the support columns; c. installing winches, arranging support ring beams in the guide columns and arranging hydraulic drive bolts and hydraulic jacks on the inner walls of and below the support ring beams respectively; d. sliding the first section of a tower drum to an installation platform; e. after adopting the winches to hoist the first section of the tower drum to a predetermined height, inserting the hydraulic drive bolts into a ring beam of the first section of the tower drum; f. using the winches to hoist the second section of the tower drum until the hydraulic drive bolts are inserted into a ring beam of the second section of the tower drum and repeating the above steps until tower drum installation is completed; and g. installing vanes and connecting the ring beams of the tower drum with the working platform by reinforcing ropes. The construction method has the following beneficial effects that: the installation cost is reduced while the fan installation requirements are met; and the construction quality is ensured.
