Abstract

The invention discloses a concrete tower drum assembly and a stretching method thereof. The concrete tower drum assembly comprises a foundation, a tower drum body, an adapter, a first prestressed tendon and a second prestressed tendon. The foundation is suitable for being arranged below the ground; the tower drum body is arranged on the foundation; the tower drum body comprises a plurality of tower drum sections; the plurality of tower drum sections are sequentially connected along an up-down direction; the plurality of tower drum sections are divided into a first group of the tower drum sections and a second group of the tower drum sections located at the upper ends of the first group of the tower drum sections; the adapter is arranged at the upper end of the tower drum body and connected with the uppermost tower drum section; the first prestressed tendon is arranged in the foundation and the first group of the tower drum sections in a penetrating manner; and the second prestressed tendon is arranged in the foundation, the first group of the tower drum sections, the second group of the tower drum sections and the adapter in a penetrating manner. The concrete tower drum assembly disclosed by the invention is high in stability and reliability; and moreover, the structure of the concrete tower drum assembly is capable of reducing stretching times while ensuring construction safety during a prefabricating process, thus increasing the construction efficiency.

Description

Technical field [0001] The invention relates to the technical field of wind power generation, in particular to a concrete tower tube assembly and a tensioning method thereof. Background technique [0002] As the power generation efficiency of the wind turbine increases, the length of the blade becomes longer and longer, and the height and cross-sectional size of the matched wind turbine tower are also increasing. Steel structure towers are difficult to meet the construction requirements of large cross-section tall towers due to their high cost and difficult transportation. The precast concrete tower can economically build large wind turbines, so it has received widespread attention. Due to transportation conditions and prefab processing conditions, complete concrete towers are often assembled from multiple individual towers on site. [0003] In the related art, due to the structural limitation of the concrete tower assembly itself, in the process of prefabricating the concrete to...
