Problems solved by technology

However, the existing reinforced concrete cylindrical foundation structures often have problems such as large local stress and complicated construction, which cannot achieve the optimal state of no cracks in the concrete structure in marine engineering. Once cracks appear in the structure, seawater will corrode the internal steel bars of the structure. , eventually leading to the destruction of the entire fan structure

Embodiment Construction

[0016] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0017] as attached figure 1 and 2 As shown, a prestressed concrete cylindrical foundation with oblique supports is composed of a cylindrical foundation 1, an oblique support 3 and a foundation transition tower section 2. The cylindrical foundation 1 is a reinforced concrete cylindrical foundation with a sealed roof The top cover is equipped with two rows of prestressed steel bars in the shape of a well; the oblique supports 3 are concrete structures, and the number of them can be arranged according to the actual situation. 10-16 can be arranged. Above, with the foundation transition tower section 2 as the center of the circle, it is evenly distributed in the radial direction; the foundation transition tower section 2 is a prestressed concrete structure that increases linearly from the upper end to the lower end, and its upper end is connected to ...

Abstract

The invention discloses a prestressed concrete cylindrical foundation with oblique supports. The prestressed concrete cylindrical foundation with the oblique supports is composed of a concrete cylindrical foundation, the concrete oblique supports, a concrete transition section and prestressed steel bars. The top cover of the concrete cylindrical foundation, the concrete oblique supports and the concrete transition section are poured as a whole. The concrete transition section is a hollow cylinder with linearly-changed diameter and thickness from the top to the bottom. The prestressed steel bars are evenly arranged in the ring direction on the wall of the transition tower section. The concrete oblique supports are evenly and radially arranged at the bottom of the transition section, and the prestressed steel bars are arranged inside the concrete oblique supports obliquely. A flange plate is embedded into the top of the transition section, and the transition section is connected with a wind turbine tower through the flange plate. The prestressed concrete cylindrical foundation with the oblique supports can improve prestressing condition of the structure, enable the structure to have no crack in the construction and the operation, enhances the durability and the stability of the structure, and is simple in improved structure, easy to construct and wide in application.

Description

technical field [0001] The invention belongs to the field of foundation structures in offshore wind power, ports, ocean and water conservancy projects, and more specifically relates to a prestressed concrete cylindrical foundation structure system with oblique supports. Background technique [0002] The wind turbine foundation is an important part of offshore wind power construction, and its structural stress and stability affect the safety of the entire wind turbine structure, and it also occupies a large proportion in the construction cost. At present, the foundations of offshore wind turbines that are widely used include gravity foundations, pile foundations, jackets and barrel foundations. As a new type of foundation, the cylindrical foundation has the following significant advantages: wide application conditions; saving steel consumption and cost; adopting negative pressure construction, the construction speed is fast, and it is convenient for gap construction in severe...
