Abstract (en)
[origin: EP0263967A1] The submersible pile hammer has a striking element which can move in a hammer casing and, in operation, is suspended on a flexible supporting element which can hang down essentially vertically. The hammer has at least one positioning device (15), arranged on itself or on a drive unit connected to it for submersing together, the positioning device serving for transverse movement and/or turning of the pile hammer hanging on the supporting element. Each positioning device has at least one rotatable propeller and/or at least one jet nozzle for producing a flow directed essentially transversely to the longitudinal axis of the hammer casing and each propeller is connected to a drive motor and each jet nozzle is connected to a compressed gas space or a combustion chamber for producing a compressed gas jet, which can be operated by control devices from above the surface of the water. <IMAGE>
