<P>PROBLEM TO BE SOLVED: To provide an installation method for an anchor device capable of easily and surely installing the anchor device regardless of the ground structure of an installation location. <P>SOLUTION: An anchor device 10 formed of an earth pressure resistance member 12 with a resistance plate 18 attached on an outside surface of a cylindrical body 16 and an anchor 14 which can be inserted inside the cylindrical body 16 is used. First, the earth pressure resistance member 12 is driven into a ground surface layer. Next, the anchor 14 is inserted inside the cylindrical body 16 from the side of a tip 14a and is deeply driven into the ground. Then, a wire is fixed to a wire fixing part 28 provided in a rear end 14c of the anchor 14 and projecting on the ground surface. In a step of driving the anchor, the anchor 14 is made to advance while excavating the ground by an excavation bit 26 provided at the tip 14a of the anchor 14. After the anchor 14 is driven, a clearance between the anchor 14 and an excavation hole 38 is filled with a coagulant 20 and the coagulant is hardened. <P>COPYRIGHT: (C)2013,JPO&INPIT |
