PROBLEM TO BE SOLVED: To increase the horizontal strength of a pile, and to prevent the cracks of pile-body concrete by constructing the cast-in-place concrete pile of reinforced concrete and introducing prestress by utilizing a steel frame between a front bearing section and a head-section bearing disk. ;SOLUTION: Jigs for introducing prestress and jacks are installed to the head-section bearing disk 11 of the upper end face section of a steel encased reinforced concrete construction and an exposed section in the upper section of a pile body of a steel frame 6 after placed concrete 5 displays specified strength, and prestress is introduced to the pile body between the head-section bearing section 11 and a front bearing section 4 by these jigs and jacks. A footing beam 15 is built at the upper end section of the pile body 5. Accordingly, the steel frame 6 such as a permanent structural column is arranged in approximately overall length in the axial direction of the central section of the reinforced-concrete constructed pile body 5, and the cast-in-place SRC pile resisting drawing and compressive force is built.;COPYRIGHT: (C)1998,JPO
