Embodiment Construction
[0037] like Figure 1-Figure 8 Among them, an offshore wind power monopile-friction wing composite foundation, which includes a single pile 1 and a friction wing 2; The outer wall of the force tube 21 is connected, and the ring wing 23 is located outside the force transmission tube 21 and connected with the side wing 22; the side wing 22, the inner side of the ring wing 23 and the outer wall of the force transmission tube 21 form an axial through structure. The conical transition section 11 of the single pile 1 goes deep into the bearing layer of the seabed, and the force transmission tube 21 of the friction wing 2 located in the bearing layer is in close contact with the conical transition section 11 of the single pile 1, and the friction wing 2 is axially Through the structure, it is convenient to embed the bearing layer of the seabed. The structural form of the side wings 22 and ring wings 23 of the friction wing 2 increases the interaction area between the composite founda...

The invention discloses an offshore wind power single pile-friction wing composite foundation and a construction method thereof. The offshore wind power single pile-friction wing composite foundation comprises a single pile and a friction wing, wherein the friction wing is connected to the single pile through a force transmission pipe, a conical transition section of the single pile goes deep into a seabed bearing stratum, and the force transmission pipe of the friction wing located in the bearing stratum is in close contact with the conical transition section of the single pile; a side wing of the friction wing is connected to the outer wall of the force transmission pipe, and a ring wing is arranged in a side wing included angle. According to the offshore wind power single pile-friction wing composite foundation, the friction wing is of a through structure in the axial direction, so that the friction wing can conveniently penetrate through a seabed sludge layer to be embedded into the bearing stratum; the side wing, the ring wing and the force transmission pipe support each other, so that the structural stability of the friction wing is kept, a soil arching effect is generated between the side wing and the ring wings by a soil body, the resistance of the soil body is remarkably improved, the interaction area of the structure and the soil body is increased by the friction wing, and the bearing capacity of the single pile-friction wing composite foundation is improved.
Description
technical field [0001] The invention belongs to the technical field of offshore wind power foundation and construction, and relates to an offshore wind power single pile-friction wing composite foundation and a construction method thereof. Background technique [0002] Domestic offshore wind power foundation structures are mainly based on single pile foundations, jacket foundations, high pile cap foundations, and barrel foundations. The single pile foundation is a 6-10m steel pipe pile, which has the advantages of clear structural force, simple manufacturing and construction process, and short construction period. It is the most commonly used foundation type for offshore wind farms with a water depth of less than 30m. The basic type accounts for more than 80%. However, for the sea areas of Fujian and Guangdong, the clay and sand covering layers at some aircraft sites are relatively shallow, and the anchorage depth of conventional single pile foundations often cannot meet th...
