PROBLEM TO BE SOLVED: To form a deep foundation readily at a reduced cost.SOLUTION: A pair of plate-form molds (31, 51) for a deep foundation is installed in an excavated part (10) facing each other, the molds for a deep foundation including a permanent mold (31) having reinforcing members (41, 42) fitted at top and bottom. Mold-width fasteners (61, 62) are spanned between the molds (31, 51) for a deep foundation for retaining an interval between the molds (31, 51) for a deep foundation, and an edge part of the permanent mold (31) is held by the mold-width fasteners (61, 62) through the reinforcing members (41, 42). Then, soil is refilled in a space outside of the permanent mold (31) in the excavated part. After refilling the soil, concrete is poured between the molds (31, 51) for a deep foundation, thus installing a deep foundation part (21).SELECTED DRAWING: Figure 4 |
