摘要： PROBLEM TO BE SOLVED: To extend design freedom by expanding a range wherein an angle of inclination of an excavating bit can be adjusted.
SOLUTION: A pile pit widening device 1 is used by being mounted on a body of rotation, so as to widen a pile pit for a cast-in-place concrete pile. The device 1 comprises a pair of excavating bits 8 and 14 which are provided symmetrically to each other by making a rotating shaft of the body of rotation serve as the center of symmetry and which can be each horizontally oscillated on positions symmetrical to each other by making the rotating shaft serve as the center of symmetry, and actuators 19 and 24 for oscillating the pair of excavating bits 8 and 14. The oscillating angles of both the excavating bits 8 and 14 are adjusted by the actuators 19 and 24, and both the excavating bits 8 and 14 are rotated with the body of rotation by setting a widening radius and an angle of inclination depending on the oscillating angle. This enables an inner wall surface of the pile pit to be widened and excavated at a predetermined depth and a predetermined angle of inclination.

摘要： PROBLEM TO BE SOLVED: To provide an cast-in-place pile construction method which reduces a concrete amount, and reduces a soil amount discharged from a site.
SOLUTION: A pile hole 20 is drilled, a soil generated by the drilling is stored in a plurality of bag bodies 21, a reinforcement cage 10 is inserted into the drilled pile hole 20, and the plurality of bag bodies 21 is fed inside the reinforcement cage 10. The concrete amount equal to a volume of a fed soil amount is reduced by feeding the soil produced by the drilling inside the reinforcement cage 10. Then, a material cost and a placing cost are reduced regarding concrete. The soil amount discharged from the site is also reduced by the fed soil amount. A treatment cost and a loading cost are reduced as well. A working cost required for constructing the cast-in-place pile 1 is remarkably reduced by this manner.
