To utilize a land effectively by forming a unit on artificial ground which is supported on a center core formed of an inner tube and an outer tube provided coaxially on the center core to construct a living block.
Many screw jack devices 32 provided with a plurality of screw rods 31 on a body of a foundation part 30 are installed to lift a steel pipe column 33 by rotating the screw rods 31. A truss is provided between the steel columns 33 which come out of the screw rods 31 in accordance with the rise of the steel pipe columns 33 to use it as a super column, and concrete is filled in the inside of the steel pipe column 33 to prepare a steel pipe concrete column. Next, the steel pipe columns 33 in the longitudinal direction are constituted into steel pipe concrete column sequentially, and artificial ground 18 is formed on an outer tube 14 and a center core 11 of an inner tube sequentially to form a unit 19 in its upper part so that a living block 17 is constructed. Consequently, it is possible to utilize a land effectively and form a large-scale collective artificial space.
