Abstract
A method for constructing a tubular pile foundation in soft soil formations comprises agitating the soft soil to form an agitated region like a tube with single annular section or tubes with conjugated annular section at a time, injecting chemical hardener and mixing it with the soft soil to solidify the agitated region in situ into a tubular pile or conjugated tubular piles. By repeating the foregoing steps, the structural wall of piles is constructed to provide bearing capacity with the soft soil formations.
