Vibratory pile hammers contain a system of counter-rotating eccentric weights, powered by hydraulic motors, and designed so that horizontal vibrations cancel out, while vertical vibrations are transmitted into the pile. The pile driving machine positioned over the pile with an excavator or crane, and is fastened to the pile by a clamp and/or bolts.
The pile hammer was a construction that allowed a heavy weight to fall on the top of the pile. Each pile wore a "pile shoe" tip made of iron. A group so hammered was called a "straddle" and atop as well as surrounding the straddle was a pile supported platform called a "starling" which was filled with rubble before the pier and bridge deck were ...

Splicing timber piles is still quite common and is the easiest of all the piling materials to splice. The normal method for splicing is by driving the leader pile first, driving a steel tube (normally 60–100 cm long, with an internal diameter no smaller than the minimum toe diameter) half its length onto the end of the leader 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]
dolphins are made of piles driven into the river bottom in a group, with space in between sometimes filled with rocks and capped with concrete. The collision is absorbed via deformations of the structure; [8] pile-supported systems on dedicated piles that are driven into the bottom either vertically or at an angle ("batter piles").
