Introduction of the method

This method involves ground stabilization. Forming improve ground in all ranges; soft to hard by an injection
of mixing cement and water. Through this method, ground can obtain a better bearing capability of the
buildings or any other structures.

Hard Soil Layers D.C.M is the implemented method which overcomes weak points of the existing method.
Through upgrading of the agitator and excavating bit, our new method has improved the problem of low
velocity and quality in the hard ground.

Weak Point

• · DCM is not easy to perform in more than N'15 ground floor, because of drilling speed slowdowns.
• · The problems as agitation of cement was to be seen at clay ground which has high adhesion.
• · The very low quality could be happened by original ground and agitation bit tangle status.
      Arise overload of auger caused decreasing of construction speed.
