Floating pile driver for jetty support beams - has parallel pontoons connected to give beam width spacing with pile driver movable on decks

摘要

The arrangement is for a pile driving pontoon to drive piles (15) for support beams for a jetty, particularly in a marina. It makes use of two pontoons (1, 2) which are connected (6, 7, 8) in parallel at a distance (3) equal to the width of the jetty support beams. The piles are driven in by a pile driving installation (9) which is movable along the deck (4, 5) of the pontoons. The distance between the pontoons may be adjustable. Pairs of guides (11-14) may be provided on the pontoon sides facing one another, which guides are spaced to assist in positioning the piles.
