Example Embodiment

[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples, and detailed descriptions are as follows with accompanying drawings:

[0025] Such as Figure 1 to Figure 3 As shown, this embodiment discloses a large-scale cylindrical foundation structure suitable for marine wind power, including large-sized cylindrical foundation 7, inverted eaves 6, ring beam 4, section steel column 3, section steel beam 2 and node connections Piece 1.

[0026] The cylindrical foundation 7 is a cylindrical steel structure foundation with a closed top and an open bottom. The outer diameter is 30m, the height of the cylinder is 10m, the wall thickness is 30mm, and the top cover thickness is 50mm. Its interior is divided into multiple compartments by installing subdivision plates. . The diameter of the cylindrical foundation 7 is usually 20-40m, and the height is usually 8-15m; the material can be reinforced concrete...

Abstract

The invention discloses a large-scale bucket foundation structure suitable for ocean wind electricity. An upwards-extending reverse eaves is arranged along the outer edge of the top cover of a bucket foundation; the middle of the top cover of the bucket foundation is provided with a ring beam; the top of the ring beam is provided with a plurality of section steel columns evenly distributed along the ring direction; a node connecting piece is arranged just above the center of the bucket foundation; a section steel beam is connected between the node connecting piece and the top of each section steel column; each section steel beam is downwards inclined from the end part on which the section steel beam is connected with the corresponding node connecting piece, to the end part on which the section steel beam is connected with the corresponding section steel column. According to the large-scale bucket foundation structure suitable for the ocean wind electricity, which is disclosed by the invention, large bending moment transferred from an upper part structure can be effectively similarly converted into tensile force and pressure on the bucket foundation by the section steel beams and the section steel columns so as to perform the largest bearing force of the bucket foundation; subdivisions can be formed by stiffening ribs between the reverse eaves and the ring beam so as to apply ballast to the bucket foundation; the capability of the bucket foundation on bearing the horizontal load and the bending moment is improved.

Description

technical field [0001] The invention relates to the field of basic structures of ports, oceans, water conservancy and bridge engineering, and in particular relates to a basic structure in which a new type of force transmission structure system is adopted on the upper part of a cylindrical foundation to optimize the force of the cylindrical foundation. Background technique [0002] At present, in the field of marine engineering such as offshore wind power projects, the foundation structures usually have pile foundations, gravity foundations, jacket foundations, negative pressure foundations and floating platforms, etc. These foundation structures usually require large machines for transportation and installation , resulting in higher construction costs and longer construction periods. Compared with the traditional foundation structure, the cylindrical foundation is widely used in marine engineering due to its low cost, convenient construction, safe and reliable use, and recyc...
