Press-in pile driving machines provide an
alternative method for installing pre-formed tubular
or sheet piles. These machines use hydraulic rams to
press piles into the ground using the negative shaft
friction of previously-driven piles to provide
reaction force (fig. 1.1). This technique eliminates
the vibration, hammering and noise pollution
associated with dynamic installation methods. Table
1.1 compares the noise created during installation of
steel sheet piles using dynamic and press-in
methods
