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.
