Title: Foundation soil improving technique for building
Inventor: MINAMI KAZUO
IPC: E02D5/18
Filed: 1994-03-29
Abstract: PURPOSE: To increase the rigidity of a cylindrical body by overlapping it on the foundation ground for a building and receiving an external force by the entire surface of the formed cylindrical body. CONSTITUTION: Cement milk is filled into the ground and agitated by the agitating device of a single- or multi-spindle excavator so as to work cylindrical bodies 1.
