Embodiment Construction

[0061] like figure 1 As shown, a self-supporting prestressed concrete steel composite tower for wind turbines includes a wind turbine foundation 1 and a steel tower section 4 above the wind turbine foundation 1, and also includes a prefabricated concrete tower section 2 and a prefabricated concrete conversion section 3 , the fan foundation 1 , the precast concrete tower section 2 , the precast concrete conversion section 3 , and the steel tower section 4 are connected by prestressed anchor beams 54 sequentially from bottom to top. In this embodiment, part of the tower section is replaced with concrete for the steel tower, which can effectively reduce the cost.

[0062] from figure 1 , 2 , 3, 4, it can be seen that the bottom of the steel tower section 4 is provided with a T-shaped or L-shaped flange 5, and holes are reserved on the flange 5, and the prestressed anchor beam 54 includes the internal prestressed anchor beam 19 and The external prestressed anchor bundle 36, the...

Abstract

The invention belongs to a prestressed concrete and steel combined tower on which a self-support wind generator set can be assembled and an anchoring method of the prestressed concrete and steel combined tower. The prestressed concrete and steel combined tower comprises a fan foundation and a steel tower cylinder section above the fan foundation and further comprises a prefabricated concrete tower cylinder section and a prefabricated concrete conversion section, and the fan foundation, the prefabricated concrete tower cylinder section, the prefabricated concrete conversion section and the steel tower cylinder section are sequentially connected through prestress anchor sheaves in the sequence from bottom to top. According to the prestressed concrete and steel combined tower on which the self-support wind generator set can be assembled and the anchoring method of the prestressed concrete and steel combined tower, a tower used for the wind generator set is divided into the concrete part and the steel part which are connected through the prefabricated concrete conversion section, and concrete is in a pre-compression state through tensioning of the internal and external prestress anchor sheaves. The concrete tower cylinder section is divided into a plurality of sections according to an actual project and formed by prefabricating and splicing in the sequence of ring pieces-ring sections-segments. The prestressed concrete and steel combined tower has the advantages of being good in quality, low in manufacturing cost, convenient to maintain and the like, the construction method is simple, and the construction speed is high.

Description

technical field [0001] The invention belongs to the field of wind power generation towers, and relates to a self-supporting wind power generation unit prestressed concrete steel composite tower and an anchoring method thereof. Background technique [0002] The global energy shortage and severe environmental and climate problems have prompted countries to pay more and more attention to the development and utilization of renewable energy such as wind energy, solar energy, and biomass energy. Wind power research started early and the technology is mature, and it has become a reusable way of renewable energy utilization. Especially in recent years, the installed capacity of wind power has achieved rapid growth. my country's wind energy is rich, of which 253 million kilowatts at a height of 10 m on land, which can be doubled at a height of 50 m; 750 million kilowatts at a height of 10 m offshore, and about 1.5 billion kilowatts at a height of 50 m. As of 2010, my country's wind ...
