Technical Field

[0001] The utility model relates to the field of offshore wind power, and in particular to a fast-operating underwater 3D printing system based on an offshore wind power pile foundation. Background Art

[0002] Due to factors such as ocean currents, waves and seabed topography, a terrain called "pits" will form around the foundation piles of offshore wind power. These pits will reduce the bearing capacity of the offshore wind power foundation, and in severe cases will even cause the foundation piles to sink, increase the instability of the structure, and thus affect the stability and performance of the wind turbine. Not only that, the pits will change the terrain, increase the wear and tear on the submarine cables, and seriously affect the efficiency of power transmission.
