Masaaki Terashi, Masaaki Katagiri, in Ground Improvement Case Histories, 2015. Sand compaction pile method. The equipment of the sand compaction pile (SCP) method resembles that of sand drain installation. When the tip is penetrated to a predetermined depth, the equipment is withdrawn, leaving a loose sand pile of predetermined length through its mandrel.

Sand Compaction Pile Method and Its Applications

高达10%返现 Aug 27, 2019 A unique ground improvement method developed in Japan, the sand compaction pile (SCP) method, improves soft ground by using vibration to install sand or any other similar material into soft ground via a casing pipe and forms sand piles in the ground. The vibratory SCP method is applied to not only cohesive ground, but sandy ground as well and is the most typically

Compozer(Sand compaction pile method)/Fudo Tetra

The composer method uses a vibrating hollow pipe for repeated driving and lifting to create large-diameter, well compacted sand piles in soft ground for ground stabilization. It is the most representative of the sand compaction pile methods and is the most widely used. This method was developed and commercialized by this company as a world-wide first. It has been implemented in all parts of
