Submergible pile driving method and apparatus for continuous operation
A submergible pile driving apparatus is suspended from a string of rigid tubes to minimize twisting during operation, and the tubes also carry conduits for transmitting hydraulic, pneumatic and electrical power to the apparatus. The upper connections to the conduits are via flexible hoses through a coupling piece inserted in the string below its point of suspension at eye, and the lengths of the hoses are adapted to the length of the pile to be driven, whereby continuous operation is possible. That is, locking beams 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.
