る力が伝達される。Since the through hole of the base plate portion is formed with a taper surface whose diameter is gradually expanded along the axis of the pile, the upper end portion of the pile is easily inserted into the through hole to form the base plate portion. The workability of connecting to the pile can be improved. Since concrete is cast between the through hole and the pile and the base plate portion and the pile are joined, the workability of the retaining wall can be improved. Therefore, the retaining wall can be easily constructed even if the labor force of workers in recent years is insufficient. And press the concrete with the tapered surface,
Since the concrete presses the pile, the force for pressing the pile is transmitted.
