Abstract
A submersible pile driving support and guide apparatus includes a tripod-like frame 8 having vertically adjustable foot pads 16, 17, a lower guide ring 21 horizontally positionable by pivotally mounted hydraulic cylinders 19, upper guiding and clamping rods 23 fully retractable into cylinders 22, and a floodable ballast tank 18. The pile 7 may be positioned vertically or at an angle by suitably adjusting the foot pads, the lower guide ring and the rods. Once it is driven down to the top of the apparatus the rods 23 are retracted into their cylinders, and the driving head 26 thereafter reciprocates within the vertical posts 9 of the frame to complete the driving.
