Ascolumn Method

※Ascolumn : Applicable Soil Cement Column
Ascolumn method is to build the stabilized soil cement column in the ground by applying slurry cement stabilizer in-situ and mixing and agitating soil and stabilizer by using a forward-reverse rotating agitator, then pulling out the rod after having reached the specific depth while continuing the agitation.

Features of Ascolumn Method
  • Soil mass "stick and rotate together" , which had been a typical problem of this method, was resolved by rotating the inner and outer rod forward and reverse at high speed to shear soil mass by force.
  • By rotating the rod forward and reverse at high speed, excellent mixing efficiency and high-strength improvement are achieved.
  • Adjustable rotation rate of the mixing blade and the strong mixing head can be applied to various soil types such as sand gravel, sandy soil and cohesive soil.
  • High vertical accuracy and balance can be obtained from the forward and reverse rotation of dual rod.
  • Soil waste can be reduced largely since soil cement column is constructed using soil in the ground.
  • Low noise and low vibration.
  • Machine can be selected from 15 ton to 120 ton according to working condition.
