。Conventionally, concrete utility poles have been made by making a cage of pre-swaged reinforcing bars, fixing this cage of reinforcing bars in a tubular formwork, and pouring concrete while rotating the formwork horizontally, applying a strong centrifugal force to form a dense pipe. It has a bottom shape. With this type of conventional concrete pole bottom shape, it is extremely time-consuming to make the reinforcing bar cage, and the nuts for embedding the scaffolding bolts must be fixed to the reinforcing bar cage so that they do not move during the rotation of the formwork. There is a problem in that it takes a lot of time and effort to do so.
