As described above, the pile foundation structure is used by placing the legs of the gantry on the upper end surface of the foundation pile. Therefore, the upper end surface of the foundation pile and the position of the legs of the gantry must be approximately the same, and the distance between adjacent foundation piles and the distance between the legs of the neighboring gantry must be approximately the same. .
However, in reality, a part of the foundation pile is press-fitted into the ground by applying vibration or pressure to the foundation pile, so that there is a difference between the position of the foundation pile and the position of the legs of the gantry. Therefore, in such a case, it was necessary to adjust the positional relationship using an adjustment tool such as an attachment between the foundation pile and the legs of the gantry. In addition, there is a problem that an extra step of installing an adjusting device such as an attachment is required, and the manufacturing cost increases because the adjusting device such as an attachment is installed.
