Added liquid supply near cutting teeth provides mixture of soil and liquid for easy penetration. At a short distance cutting teeth are a number of soil mixing teeth welded on which penetrate inside hollow drill tube. The standard mobile pile driving machine (15), has rotary table (16) and frame (17) sliding in reciprocating mode over telescopic mast (18) which is supported on mobile frame (19).
