PROBLEM TO BE SOLVED: To improve the work efficiency for pile head treatment when constructing a cast-in-place concrete pile.;SOLUTION: By fixing annularly a pile head treatment bag of a columnar shape inflated with the air along a hoop reinforcement in a gap between the hoop reinforcement at the pile head and a holding reinforcement on the inner side of the hoop reinforcement and then casting concrete, weld overlay around an inner side of a reinforcement cage may be removed when the pile head treatment bag is removed. This eliminates the need to crush the weld overlay around an inner side of a reinforcement cage with a drill or other equipment, which has caused a decline in the work efficiency for pile head treatment, thereby enhances the work efficiency for pile head treatment.;COPYRIGHT: (C)2015,JPO&INPIT
