Problems solved by technology

[0005] The object of the present invention is to provide an underwater anti-scouring protection method and device to solve the problem that the underwater anti-scouring measures in the prior art are prone to scour due to covering the edge of the shelter area, and when coverings such as riprap and sandbags are covered by the seabed The technical problem that the seabed foundation will be seriously affected by erosion after the water flow breaks away from the design protection range of the seabed

Abstract

The invention discloses an underwater scour protection method and a device, and relates to the technical field of offshore wind turbine foundation scour prevention. The underwater scour prevention method defined in the invention comprises the steps of overlapping and fixing the bottoms of a plurality of artificial seaweeds to strings, and forming artificial seaweed units; connecting the strings vertically and horizontally to a string net; connecting the string net to a ballast or an anchoring device to form the underwater scour protection device; sinking one or more underwater scour protection devices to corresponding positions around a seabed foundation. In the invention, the technical problems are solved that the scour phenomenon easily occurs in underwater scour protection measures due to covering of protection range edges in the prior art, and the seabed foundation is affected by scour severely after ripraps, sandbags and other coverings are rushed out of the seabed design protection range by subsea current.

Description

technical field [0001] The invention relates to the technical field of anti-scouring technology for offshore fan foundations, in particular to an underwater anti-scouring protection method and device. Background technique [0002] The foundation of offshore wind turbines is located in a very complex environment. Under the action of ocean dynamics, seabed sediments are easily carried away by seabed currents, forming scour pits around the foundation. The scouring effect reduces the buried depth of the foundation, and seriously affects the bearing capacity of the foundation and the stability of the superstructure. Traditional anti-scouring measures for offshore wind turbine foundations, such as riprap and sandbag methods, are passive defense measures that protect the soil particles around the seabed foundation from being carried away by water flow by covering and covering. [0003] However, the inventors of the present application found that the traditional anti-scouring measu...
