Paper on Underwater Noise Reduction of Marine Pile Driving 

GeoPrac.net [2017-01-06 01:19:18]  recommend  recommend this post  (2 visits) info
Impact pile driving of steel piles in aquatic environments produces extremely high underwater sound levels. To address this problem, a double-walled pile has been developed to decrease the total noise transmitted into the water and substrate. The double-walled pile consists of two concentric steel pipe piles flexibly connected by a special driving shoe, allowing for an air gap between the two tubes. The double-walled pile is driven into the sediment by using traditional equipment that strikes [...]
