ADW Steel Pile

POSCO – South Korea

• Recently, as the number of construction projects in downtown areas increases, mitigating noise and vibration in pile driving operations is becoming more important than ever.
• ADW pile is a type of rotary pile designed with a helical blade, so that it is can minimise noise, vibration, and dust during construction process.
• Since the bit is attached to the pile tip, it can penetrate even in hard ground, and high bearing capacity
  can be demonstrated due to the large diameter of pile shaft.

Characteristics

• No noise
  By penetrating the ground using
  pile rotation, this method can minimise noise.
• No waste
  Since there is no discharge of soil,
  it is possible to maintain a clean site.
• No vibration
  Since pile driver and vibratory hammers are not used for the penetration of piles, vibration can be minimized during construction.
• No dust
  Dust can be minimized because of no excavation process
