PURPOSE:To accurately divide not-yet-cured concrete at an expected dividing position, by fixing a cartridge filled with a dividing agent having an expansive hydration in a vessel at bearing rods arranged in expected positions of a cast-in- place pile to place readymixed concrete. CONSTITUTION:A dividing agent 2 with expansive hydration is filled in a vessel 1 made from net-bags extrusively molded and shape-formation parts 3 are pressed with pressure in the radial direction and sealing parts 4 having heat-seal lines are formed at specified positions to enclose the dividing agent 2 and to constitute a cartridge 5 made of compartments 1b-1n in turns. This cartridge is divided and fixed horizontally by steel wires at the bearing rods 8 arranged as a sharp-form in the expected dividing positions 7 of a cast-in-place pile 6. And readymixed concrete is placed to form a not-yet-cured concrete pile 9 and the concrete pile 9 is cut horizontally after about 15 days. In this way, the sealed position can be adjusted and the not-yet-cured concrete can be cut horizontally from the expected dividing place.
