(a) Various splices are available to connect concrete piles. The splice will provide the tensile strength required during driving when the resistance to driving is low. Figure 1-2a illustrates the cement-dowel splice. Refer to “Foundations” (Pile Buck Inc. 1992) for additional splices.
(b) Special steel points can be attached to precast precast piles during casting of the piles and include steel H-pile tips or cast steel shoes (Figure 1-2).
