PURPOSE: To eliminate useless boring and consumption of a material, by a method wherein a boring for a core-inserted pile is conducted down to a sufficient depth to allow the support of a wall body, and a boring for coreless pile is made down to only a depth being necessary to cut-off.
CONSTITUTION: In a stratum containing a water impermeable layer around a pit excavation bottom, a boring for a core inserted pile 1 serving as a core is conducted down to a given depth from a pit excavation bottom level, and a boring for a coreless pile 2 serving as a wall part is made down to a depth to allow the slight touch of it to a water impermeable layer present around the pit excavating bottom. This enables boring of only a core part, supporting a wall body, down to a sufficient depth which results in enabling building of a rational soil sheathing wall matching a soil constitution and in eliminating an useless boring and consumption of a material.
