Abstract:
A tubular piling driving apparatus for securing an upright tubular piling into the bottom of a body of water comprising:an elongated pressurized fluid actuator having a longitudinally extending shaft extending from an upper end thereof;said actuator including a first inlet for receiving pressurized fluid which causes said shaft to extend longitudinally from said actuator to a first position and a second inlet for receiving pressurized fluid which causes said shaft to withdraw longitudinally into said actuator to a second position;a collar sized for supportively fitting over an upper end of the tubular piling, said collar having a central support for supportively receiving said actuator substantially in longitudinal alignment within the piling;a weight support connected to a distal end of said shaft and a weight supportable atop said weight support;said weight alternately positioned above said collar when said shaft is in said first position and against said collar when in said second position whereby, when pressurized fluid is transferred from said first inlet to said second inlet, said weight impacts downwardly against said collar to drive the piling into the bottom.
