Method that improves the noise of existing S.C.P.

1. Method overview

1) The existing vibration compaction pile method forms piles using the strong vibration force of a hammer and high-pressure AIR during construction, so it generates large vibration and noise during work, which causes complaints from surrounding areas, deformation and damage to structures, ground subsidence and cracks, and collapse. This is a compaction pile method that minimizes vibration and noise, which are the biggest problems of existing methods.

2) A method that excavates the ground using the rotational force of an auger and its own weight (auger + casing), and then compacts the material injected into the casing through extraction and re-penetration to form a pile. 

3) Prevents liquefaction, increases horizontal resistance, reduces and promotes ground compaction, increases shear strength and bearing capacity, and suppresses lateral displacement. 

2. Method characteristics

1) Eco-friendly method

  ① The vibration and noise levels are below the environmental regulation standards, so they have little effect on the surrounding areas. ② Noise separation distance 10M: 70.0dB(A) or less

  ③ Vibration separation distance 10M: 55.0dB(A) or less

    (Refer to the service report of the Korea Noise and Vibration Research Institute)

2) Diversity of materials used 

  ① The selection of materials used is free, and sand, crushed stone, recycled aggregate, slag, etc. can be used depending on the site conditions

3) Ease of quality control 

  ① Construction is possible through real-time monitoring by an automated system, enabling the creation of high-quality compaction piles

4) Diversity of applicable ground 

  ① Excellent applicability to sandy soil, clayey soil, weathered soil, etc. as penetration is achieved through auger drilling
