Sand Compaction Method

Vibro Hammer for Sand Compaction Pile Methods (SCP method)
Vibro Hammer for Sand-Drain Pile Methods (SD method)

Vibro Hammer for Ground Improvement with both unprecedented powerfulness and quietness



Feature

Sand Drain Methods (SD methods) and Sand Compaction Pile Methods (SCP methods) are used for the construction of ground stabilization and preventing liquefaction for the soft ground in the deep area of ports. And recently the casing pipes become more longer and bigger diameter.
Because of this, Vibro hammers, which are used for driving and extracting the casing pipes, are required to be more bigger and to have higher performance.
CV series are low frequency vibration hammers having both bigger amplitude and centrifugal force.
Also CV series are very much reliable due to the special high performance and durability in the site both in the sea and on the land and recognized as the main machines of ground improvement.

  1. High Performance
    Combined the absorber to the Vibro itself,acheaved high driving force to the top resistance of the ground.

  2. Low noise level
    Acheaved low noise by the design knowhow from the long experience and latest manufacturing technology.

  3. Durability
    Available of high performance works coming from the ideas of structure and design performing long time operation.
