AI Technical Summary

Technical Problem

Traditional wind turbine foundations are complex in structure, require a large amount of steel reinforcement, have a long construction period, are expensive, and are prone to breakage, which hinders the development of the wind power industry.

Method used

The steel-reinforced concrete prestressed wind turbine foundation consists of a steel frame structure and a prestressing system. It is composed of steel components, vertical reinforcing bars, connecting sleeves, and prestressed anchor bolts, which optimizes the wind turbine foundation structure and reduces the density of steel bars and the amount of concrete used.

Benefits of technology

It effectively reduced the amount of steel bars and concrete used, reduced construction difficulty and time, lowered costs, and improved the load-bearing capacity and structural simplicity of the wind turbine foundation.

Abstract

The utility model relates to the technical field of wind power generation, in particular to a steel reinforced concrete prestressed fan foundation, which is optimally designed on the basis of the traditional gravity expansion type foundation, and provides a novel structure from the structural form, and the structure comprises an original fan foundation, a steel reinforced structure and a prestressed system. A foundation stand and a foundation circular truncated cone are arranged on the top of an original fan foundation, and a base plate of the foundation is arranged on the lowest portion of the foundation. The steel rib structure is composed of a profile steel component arranged in the foundation stand, a connecting sleeve connected to profile steel and a vertical erecting steel bar used for fixing the profile steel, and meanwhile corresponding stiffening ribs are arranged at the position of the connecting sleeve. The prestress system is composed of vertically-arranged anchor rods, anchor plates, anchor bolts and circumferential prestress steel bars, and the bearing capacity of the fan foundation can be effectively enhanced. The structure can effectively reduce the use amount of concrete and steel bars, and the steel ribs are high in bearing capacity and replace a large number of steel bars, so that the work amount is reduced, the construction period is shortened and the manufacturing cost is reduced.
