<p>PROBLEM TO BE SOLVED: To increase a degree-of-freedom of design of a dam body with a precast wall body higher than before.SOLUTION: A dam body includes a wall body connecting steel material 20 for connecting a precast wall body 16 and a footing 14. The footing 14 has an upper opening hole 14X, a protruding sheath pipe 14A is provided on an inner surface of the upper opening hole 14X, and the footing 14 has lower opening holes 14Y at a spacing in a direction substantially orthogonal to the normal direction of the precast wall body 16 with respect to the upper opening hole 14X. A sheath pipe 14B for a pile is provided on an inner surface of each of the lower opening holes 14Y, and a protruding sheath pipe 14A is inserted into a wall body sheath pipe 16A of the precast wall body 16. The wall body connecting steel material 20 is inserted into and integrated with the protruding sheath pipe 14A, and a steel pipe pile 12 is inserted into and integrated with each of the sheath pipes 14B for the piles. Moreover, orthonormal connection steel materials 14C, 14D for connecting the protruding sheath pipe 14A and the sheath pipes 14B for the piles to each other are provided in the footing 14.</p> |
