Title:
APPARATUS AND METHOD FOR REINFORCING AND RECTIFYING OFFSHORE WIND TURBINE MONOPILE FOUNDATION
Document Type and Number:
WIPO Patent Application WO/2024/007618
Kind Code:
A1
Abstract:
An apparatus and method for reinforcing and rectifying an offshore wind turbine monopile foundation. The apparatus comprises a steel casing (11) fixedly sleeved on the wind turbine monopile foundation, and a plurality of steel frame structures (12) are uniformly fixed on the steel casing (11) in the circumferential direction; a composite foundation (4) is provided around the wind turbine monopile foundation, and the composite foundation (4) is formed by injecting cement into a soil body and performing stirring and reinforcement; a plurality of precast piles (3) used as ground anchors are provided in the composite foundation (4), and the plurality of precast piles (3) are annularly and uniformly arranged by using the wind turbine monopile foundation as a center; the steel frame structures (12) are connected to the precast piles (3) by means of anchor cables (2). During operation, the specific anchor cables (2) are tensioned in a graded manner to apply an external pulling force to the wind turbine monopile foundation, thereby realizing deviation rectification. The apparatus can solve the problems that a local scouring pit is enlarged and the mechanical property of a soil body is weakened, and can also realize comprehensive improvement of the vertical, horizontal and torsional bearing capacity of an original wind turbine monopile foundation.
