Embodiment Construction

[0030] Such as figure 1 As shown, the leveling structure of the offshore wind turbine foundation 20 according to the present invention includes two or more pipe piles 10, and the pipe piles 10 are respectively fixed and installed on the seabed, and the pipe piles 10 are connected to the wind turbine foundation 20 Each fan foundation 20 is fixedly connected with a foundation support plate 40 , and an adjustment pad 30 is provided between the foundation support plate 40 and the pipe pile 10 .

[0031] Using the leveling structure of the offshore wind turbine foundation 20 of the present invention, each wind turbine foundation 20 is inserted into each pipe pile 10 correspondingly, so as to install and fix each wind turbine foundation 20 . And between the fan foundation 20 and the pipe pile 10, an adjustment pad 30 is set, and the deviation between the fan foundation 20 and the pipe pile 10 is offset by changing the thickness of the adjustment pad 30, so as to ensure the foundatio...

Abstract

The invention relates to a leveling structure and leveling method for sea fan foundations. The leveling structure for the fan foundations comprises two or more than two pipe piles, wherein the pipe piles are fixedly mounted at the bottom of the sea, the pipe piles are connected with the fan foundations, each fan foundation is fixedly connected with a foundation supporting plate, and adjusting cushion blocks are arranged between the foundation supporting plates and the pipe piles. Through the adoption of the leveling structure for the sea fan foundations, each fan foundation is correspondingly inserted into each pipe pile so as to mount and fix each fan foundation. Besides, the adjusting cushion blocks are arranged between the fan foundations and the pipe piles, deviation between the fan foundations and the pipe piles is counteracted by changing the thickness of the adjusting cushion blocks, so that the foundation supporting plates of each fan foundation are ensured to be positioned on the same plane, and better flatness is supplied to sea fans and anemometer towers. As known, the method disclosed by the invention replaces an existing method which uses a hydraulic lifting system to improve the flatness of the fan foundations. Compared with the prior art, the leveling structure disclosed by the invention has the advantages of simpler structure, stronger operability, and higher cost performance.

Description

technical field [0001] The invention relates to the technical field of offshore wind turbine foundations, in particular to a leveling structure and a leveling method for offshore wind turbine foundations. Background technique [0002] Offshore wind power has developed rapidly in the field of new energy due to its advantages of cleanliness, safety, and high development efficiency, and the basic design of offshore wind turbines and wind measuring towers is an important part of it. The foundations of various wind turbines, such as jackets, underwater three piles and above water three piles are gradually widely used. However, considering the safety and durability of fan operation, people have very strict requirements on the control of the installation error of the fan foundation. How to ensure that the verticality error of the fan foundation is controlled within the specified range during foundation installation is very important. The verticality error of the fan foundation is ...
