GROUTING-FREE DRY-TYPE PRESTRESSED BOLT SEGMENT-ASSEMBLED PREFABRICATED CONCRETE TOWER
The present invention discloses a grouting-free dry-type prestressed bolt segment-assembled prefabricated concrete tower, comprising a top steel tower tube, a reverse self-balancing steal-concrete transition section, and a prestressed-bolted dry-assembled segmental precast concrete tower with grouting-free dry fast splicing and a gear reinforced wind turbine foundation; the steel tower tube, the steel-concrete transition section, the concrete tower tube and the hollow wind turbine foundation are integrally connected from top to bottom through a prestressed steel strand system to improve the overall bending resistance of the tower; the upper end of the prestressed steel strands is anchored to the steel-concrete transition section, and the lower end is anchored to the bottom face of the wind turbine foundation corbel; the concrete tower tube is composed of a number of segmental tapered precast concrete tower segments, which are grouting free spliced vertically, and the vertical splicing utilizes positioning pins to accurately position the installation position. The prefabricated concrete tower tube segment is formed by a number of circular arc-shaped prefabricated concrete tube segments with circumferential grouting free dry splicing. The segments are spliced into a whole by prestressed bolts and then installed staggered from top to bottom to enhance the shear resistance.
