Fig. 5.6 Detail of junction between topmost concrete segment and steel adapter
Each segment is supported and aligned at three points.
The joints between the segments take the form of filled joints with spacer blocks.
Sealing rings prevent the grout from seeping into the ducts for the prestressing tendons.
The joints are prepared with a layer of high-strength mortar and filled completely after
each segment has been aligned.
Figure 5.6 shows the junction between the topmost concrete segment and the steel
adapter to which the rotor mounting is attached. The steel adapter is fixed and aligned
by means of four site bolts. Only after all segments have been erected are the
prestressing tendons threaded through from the top. Figure 5.7 shows the junction
between the bottommost segment and the foundation with its stressing point in a space
within the foundation.
