A Precast Post-Tensioned Segmental Pole System
The pole system described in this paper can be used in lengths up to 36 m (120 ft) on a standalone basis or as a component in a structure. Service environments for the system include electrical transmission and distribution, lighting, and communications. Criteria for the pole system development involve ease of manufacture and installation, serviceability, appearance, and cost effectiveness. The resulting pole system contains 1 to 4 segments up to 9m (30 ft) in length each with a tapered static precast concrete hexagonal cross section having 64 mm (2½ in) thick walls and a hollow interior that can be filled with pumped concrete or left empty after installation. Post-tensioned prestressing tendons occur inside the wall of the precast concrete. The numbers and distribution of the tendons vary with the pole applications that allow outside diameters across the flats of the hexagonal cross a section from 250 mm (10 in) to 850 mm (34 in) with a taper of 25 mm (1 in) per 3 m (10 ft). Precast forms have been built for this pole system and are being used for prototype manufacture. Some of the pole prototypes will be installed by a variety of construction techniques. This work, along with suggestions for future implementation steps, will be shown in the paper.
