Steel cylinder foundation structure and equipment and construction method of steel cylinder foundation structure

The invention discloses a steel cylinder foundation structure and equipment and a construction method of the steel cylinder foundation structure. A steel cylinder foundation comprises a steel cylinder (3) which is used for being connected with a tower drum (1) of a wind driven generator. The connection part between the steel cylinder (3) and the tower drum (1) is provided with long circular holes. The steel cylinder (3) and the tower drum (1) are connected through high-strength fastening pieces (2) penetrating through the long circular holes. According to the steel cylinder foundation structure, the perpendicularity of a tower is finely adjusted through the long circular holes in the connection part between the steel cylinder foundation and a tower body, inclination of the foundation is corrected within an allowed range, the steel cylinder foundation and the tower body are spliced through high-strength bolts in a double-shear mode, no weld joint exists, the anti-fatigue performance is good, and the structure is simplified; by means of the construction method of the steel cylinder foundation, the problem existing in leveling due to perpendicularity deviation caused by piling is solved simply and feasibly, and meanwhile no adverse influence is imposed on stress in later normal operation.
