Offshore wind turbine foundation and construction mechanism thereof

Abstract

The invention discloses an offshore wind turbine foundation which is fixed into pipe columns with openings. The offshore wind turbine foundation comprises a first body, a connecting plate and a second body which are sequentially arranged from top to bottom. One side of the connecting plate is connected with the first body, and the other side of the connecting plate is connected with the second body. The ends, away from the connecting plate, of the second body extend into the openings and are connected with the pipe columns. When the pipe columns are deflected from the preset installation position and the deflection of the pipe columns exceeds the permitted construction error, the second body can be deflected from the connecting plate by a certain degree so that the second body can be smoothly inserted and fixed into the pipe columns. The offshore wind turbine foundation is simple in structure and high in operability, the situation that the deflection permitted column sinking error is large can be rapidly remedied, the smooth installation of the offshore wind turbine foundation can be ensured, and the offshore construction installation efficiency and reliability are improved; the pipe columns which are large in construction error do not need to be specially processed, and the economic benefits of the offshore wind turbine foundation are good.

Description

technical field [0001] The invention relates to the technical field of offshore wind turbine foundations, in particular to an offshore wind turbine foundation and a construction method thereof. Background technique [0002] In the current wind turbine foundation forms such as jacket, underwater three-pile and above-water three-pile, the construction sequence of laying pipe piles first, and then installing the wind turbine foundation is adopted. Due to errors in the construction of pipe piles, when the error exceeds the specified range, it will be It will affect the smooth construction of fan foundation. For example, when the construction position of the pipe pile deviates from the predetermined installation position by a large distance, the wind turbine foundation cannot be smoothly inserted into the pipe pile. At this time, the pile will be re-drilled or other special offshore treatment will be carried out, which will seriously affect the construction efficiency and increas...

[0002] In the current wind turbine foundation forms such as jacket, underwater three-pile and above-water three-pile, the construction sequence of laying pipe piles first, and then installing the wind turbine foundation is adopted. Due to errors in the construction of pipe piles, when the error exceeds the specified range, it will be Will affect the smooth construction of fan foundation

For example, when the construction position of the pipe pile deviates from the predetermined installation position by a large distance, the wind turbine foundation cannot be smoothly inserted into the pipe pile. At this time, the pile will be re-drilled or other special offshore treatment will be carried out, which will seriously affect the construction efficiency and increase the construction cost.

In addition, when large-scale construction is carried out, it is difficult to avoid the phenomenon that the pipe pile deviates from the allowable construction error range
