PURPOSE:To construct the foundation which is excellent in a support force and an earthquake resistant force, by a method wherein foundation piles, which are continuously connected with each other, are simultaneously driven by means of a 3-shaft agitating rod by the use of an improved hardener, the foundation piles are continuously connected in a lattice shape, and intersection parts and corner parts are filled with a core body. CONSTITUTION:By means of a 3-shaft rod 9 having agitating vanes 12 and injection holes 13, which is located at the lower end of a driving machine 7 having a 3-shaft swivel 8, triplex foundation piles 2 are simultaneously driven in a ground, where foundation is intended to be constructed, by the use of an improved hardener. The foundation piles 2 are continuously driven, in order, to construct a latticed wall 6, and the intersection parts and corner parts of the foundation piles 2 are filled with a core body 3, such as steel pipes, and are cured to construct a foundation. This enables a total foundation to be integrally constructed, and enables provision of the foundation which is high in a supporting strength, earthquake resistant force, and horizontality. |
