PROBLEM TO BE SOLVED: To provide a securing method for a pile head reinforcing bar insertion space in a foundation pile with a hollow section which can accurately form and secure the pile head reinforcing bar insertion space, does not require the wasteful removing work of a cement milk hardened body, and can accurately prevent a drop accident of a worker into the hollow section. SOLUTION: A mesh 2 is provided at the upper end of a foundation pile 1, a mesh 4 is provided below the mesh 2, by the height for burying pile head reinforcing bars 3, and a protective plate 5 is fitted to the upper mesh 2. After the foundation pile 1 is executed and a pit excavation is made around the pile head, the upper mesh 2 is cut, the protective plate 5 is moved onto the lower mesh 4, and the pile head reinforcing bars 3 are buried on it and connected to an upper mount structure, or an area injection doughnut body may be inflated and inserted into the upper end of the hollow section of the foundation pile 1.
