There are many different types and systems of piles, however the main types are:
(1) Driven precast piles.
(2) Driven cast in situ piles.
(3) Bored piles.
(4) Augered piles.
These piles can also be divided into either displacement or replacement methods dependent on the system of driving, i.e. either removal of material, termed replacement, or wedging apart of material, termed displacement. Typical examples of these types are shown in Fig. 9.35.
