ABSTRACT:
A submergible pile driving apparatus is suspended from a string of rigid tubes 12 to minimize twisting during operation, and the tubes also carry conduits 18, 19 for transmitting hydraulic, pneumatic and electrical power to the apparatus. The upper connections to the conduits are via flexible hoses 25, 26 through a coupling piece 20 inserted in the string below its point of suspension at eye 13, and the lengths of the hoses are adapted to the length of the pile 7 to be driven, whereby continuous operation is possible. That is, locking beams 16 may be engaged with a tube flange to take up the weight of the suspended string and apparatus while a further tube is added to the upper end of the string, without interrupting the driving operation.
