摘要： PROBLEM TO BE SOLVED: To provide a method for controlling the degree of verticality of a PC hollow pile, which enables the degree of verticality of the PC hollow pile to be controlled by erecting the PC hollow pile with high degree of accuracy in a planned position, while keeping the degree of the verticality of the PC hollow pile within a range of a specified value.
SOLUTION: In this method for controlling the degree of the verticality of the PC hollow pile, when an upper end of the PC hollow pile 2 is fixed by supporting means 14 and 18 which are provided on the earth's surface so that the hollow pile can be erected in a suspended state in an excavated ditch 4, one end of a measurement string 30 is fixedly attached to a locking rod 12, which is provided in the lower part of the PC hollow pile through its axial core part, in such a manner as to be pre-positioned in its axial core part, and the other end thereof is precedently led out upward from the upper end. After the erection of the PC hollow pile, a tower-shaped measurement platform 34 is installed above the PC hollow pile; the other end of the measurement string is fixedly attached to the measurement platform and provided in a stretched state; and the fixedly attached position of the end on the side of the measurement platform is adjusted so that the measurement string can be set vertical while collimation is performed from two directions by a transit 36. After the completion of positioning, a displacement between the axial core position of the upper end of the PC hollow pile and the measurement string is measured, and the degree of the verticality is controlled by correcting the fixed position of the upper end of the PC hollow pile so that the displacement can fall within the range of the specific value.

摘要： PROBLEM TO BE SOLVED: To provide a PC hollow pile for constructing a wall body, which can be erected while keeping the dimensional accuracy of the separation of the PC hollow piles high, when the wall body is constructed by bringing the PC hollow piles into continuous contact with one another, and to provide a construction method for the PC hollow pile.
SOLUTION: In a method for constructing the wall body, an insertion ditch 4 for the PC hollow pile is excavated over a predetermined length along a wall-body constructing line. The PC hollow piles with a rectangular cross-sectional surface are erected in the insertion ditch, fixed by supporting means 14 and 18 which are provided on the earth's surface, put into a suspended state in the insertion ditch, and continuously provided in a line in such a manner as to sequentially adjoin each other. In this case, one engaging piece 10a of an engaging means, which is provided on the lower part of the PC hollow pile on the side of precedent arrangement, is engaged with the other engaging piece 10b of an engaging means, which is provided in the lower part of the precedently arranged PC hollow pile, from above, while the PC hollow pile to be subsequently arranged along the precedently arranged PC hollow pile as a guide is lowered in a suspended state. Self-hardening slurry 24 is pre-infilled as a solidification material into the insertion ditch at the stage of the excavation of the insertion ditch, and the solidification of the slurry makes the solidified slurry fix the PC hollow piles in the state of enclosing the periphery of the PC hollow piles continuously provided in a line.
