Abstract

The invention discloses a jacket wind turbine foundation connecting piece which comprises a jacket, wherein a connecting piece steel pipe is sheathed outside a jacket top steel pipe, a steel block is fixed on the outer wall of the jacket top steel pipe and / or the inner wall of the connecting piece steel pipe, and a grouting material is filled in a clearance between the jacket top steel pipe and the connecting piece steel pipe; and a sealing ring is arranged at the lower end of the connecting piece steel pipe, and a wind turbine tower drum is sheathed outside the connecting piece steel pipe. By adopting the jacket wind turbine foundation connecting piece, accurate leveling of the top of the connecting piece steel pipe is ensured, the hoisting requirement of the upper wind turbine high-rise structure is achieved, and the jacket wind turbine foundation can be popularized and applied in the offshore wind farm field.

Description

technical field [0001] The invention relates to a jacket fan foundation, in particular to a jacket fan foundation connecting piece. Background technique [0002] The jacket foundation has been widely used in the construction of offshore oil platforms and offshore lighthouses. It is understood that my country's offshore oil jackets set up in the Bohai Sea and East Sea waters with a depth of 15m to 80m all use jacket foundations. In the field of offshore wind farm foundation design, when the unit capacity is large and the water depth is deep, the jacket foundation type has obvious advantages in terms of structure type, project cost, and construction progress compared with other types of wind turbine foundations. [0003] At present, the structural type of the jacket fan foundation of the general offshore wind farm is: hoisting and sinking the jacket, driving the pile into the seabed along the rigid casing of the jacket foundation, and between the pile and the rigid casing of ...
