Abstract: An improved pile driving method is disclosed, which is particularly applicable in piling into a hard rock bed widely in the construction of buildings, bridges, harbor facilities, piers and so forth, and in which a high-pressure water guide pipe is attached to a pile to be driven, in a manner of being movable within a certain limit, and while effecting a removal of rock pieces produced by crushing by the pile driving, through jetting a water supplied under pressure through the guide pipe, driving of the pile is worked by a vibration pile driver. This method employs a reduced amount and suppressed pressure of water to be jetted in comparison to conventional methods.
