摘要： A jacket pile cleanout device for cleaning in situ the interior of an offshore piling including a fluid accumulation jetting chamber for accumulating and jetting a fluid against debris within the interior of a pile casing and a pumping chamber connected with the accumulation chamber. The pumping chamber is fashioned with a fluid inlet and fluid exit with a means for introducing pressurized gas into the interior of the pumping chamber between the fluid inlet and the fluid exit. The pump serves to lift fluid and fragmented matter within the piling to the surface by a gas lift.

摘要： A method of reinforcing, in situ, a piling comprising the steps of: gaining access into the pile casing, cleaning mud and debris from the interior of the casing and simultaneously removing the debris, inserting stiffening or reinforcing material into the casing and sealing the pile casing access opening. The step of simultaneously cleaning and removing is essentially performed by a pile cleanout device comprising a fluid jetting portion operable to dislodge and fragment sediment and other debris within the jacket pile casing, and a gas lift portion integral therewith to remove the fragmented matter from the interior of the pile casing.
