Telecommunication sector is one of the fastest developing sector of Bangladesh, now linking no less than 50 million active subscribers. In a flat riverine country like Bangladesh, the mobile telecommunication operators have chosen steel-lattice towers as a plausible option to mount antennas for the backbone network. The foundation for such lattice structures are usually rested on tension piles. To this end, use of spun-prestressed predrilled nonspliced concrete piles up to 12m in length is a viable option in most of teh soil conditions of Bangladesh. The conventional spun-prestressed concrete pole factories can be modified for manufacturing of these piles. These factory manufactured piles give the possibility of faster construction with assured quality.
We checked the design and tested the Uplift capacities of spun-prestressed predrilled nonspliced precast hollow piles for use in founding antenna support structures. The piles have been successfully used in supporting telecommunication towers up to 90m in height at different locations of Bangladesh.
