An Emeca mechanical pile splice. The rebar on the back side will be cast into the end of a concrete pile.

A pile splice joins two segments of a driven pile, using either a weld (typical for H beams), grout or mechanical means (typical for precast concrete piles). Pile splices enable the use of shorter segments, which allows for driving piles in low-headroom situations such as under bridges or inside buildings.[1] Reducing length of pile segments to under ~65 feet long also means the trailers that haul them to job sites can stay within state length limits.[2]

With splices cast into the end of each segment of concrete pile, the pile driving crew just 1) lines up the segments; 2) connects the splice and 3) drives in the locking pins.
