欠損を生じる。2. Description of the Related Art Conventionally, a method of suspending a pre-assembled reinforced cage at a place where a cast-in-place pile is to be placed on the ground and jointing the reinforced cage into a hole is conventionally performed. However, these conventional methods have the following problems. Depending on the construction site, there is no space for assembling the reinforced cage in advance, nor is there an upper space for installation. The workability is reduced because the steel cage is built in the borehole while jointing. The work floor must be lowered by the amount of space required for the work, and the groundwater level is lowered, which adversely affects the surrounding environment. In order to solve these problems, there is a method using a flexible reinforcing bar, but this method also has the following problems. When attaching the hoop to the flexible reinforcing bar of the main reinforcing bar, it takes a long time to weld the wrap portion of the hoop, resulting in poor work efficiency. Due to the welding operation of the wrap portion of the hoop rebar, the main rebar has a cross-sectional defect.
