Zusammenfassung:PROBLEM TO BE SOLVED: To provide a pile hole wall stabilizing method for a cast-in-place pile, which is implemented by a simple structure, low in cost, positively stabilizes a pile hole wall, and is applicable even to a narrow construction field. SOLUTION: In the pile hole wall stabilizing method for the cast-in-place pile, shear reinforcements are inserted into pile hole peripheral ground of the cast-in-place pile, concentrically around the pile hole so as to extend along the entire periphery of a concentric circle or to follow the concentric circle at intervals, down to a predetermined depth. In this manner deformation and shear fracture of the cast-in-place pile hole wall can be prevented. COPYRIGHT: (C)2008,JPO&INPIT
