PROBLEM TO BE SOLVED: To easily carry out the construction of a pier foundation or the like of a multi-support foundation type.;SOLUTION: In the construction of the pier foundation, a pile anchoring unit 3 which has a casing 3a having an inner diameter insertable into a foundation pile 2 with a space from the outer periphery of the pile, and a tube 5 which is inflatable inward of the casing, and arranged in a tube storage member 3b at the lower edge of the casing 3a is fitted to the outer periphery of the foundation pile 2, and a footing form is formed on the pile anchoring unit 3. Then the footing form inclusive of the pile anchoring units 3 is moved to an anchoring location, and each tube 5 is brought into intimate-contact with the entire outer periphery of the foundation pile 2, and grout is filled into a gap enclosed by the inner periphery of the casing 3a, the outer periphery of the foundation pile 2, and the tube 5, and then hardened, to thereby anchor the footing form to the outer periphery of the foundation pile 2.;COPYRIGHT: (C)2008,JPO&INPIT
