Wind turbine tower and method of production thereof

摘要

A wind turbine tower is made of reinforced concrete with fiber rovings as reinforcements, wherein the fiber rovings are basalt fiber rovings. In one embodiment, the basalt fiber rovings may include, for example, a bundle of multiple parallel oriented basalt fibers forming a thin rope. In one embodiment, the tower is produced in a slip forming process or slip molding process, wherein the basalt fiber rovings are embedded in the concrete during the slip forming process.

1. A slip-formed wind turbine tower comprising,
a reinforced concrete hollow structure with fibre rovings as reinforcements, wherein the fibre rovings are basalt fibre rovings, and wherein the basalt fibre rovings are embedded in the concrete during the slip forming process, wherein each of the basalt fibre rovings are embodied as a bundle of multiple parallel oriented basalt fibers, and wherein at a top portion of the tower, the tower adapts to a yaw-construction, and the basalt fibre rovings are placed in paths that deviate from the parallel path orientation found in a portion of the tower below the top portion in order to cope with the intensive tensions and stresses which act on this part of the tower.
