PROBLEM TO BE SOLVED: To provide anchor structure capable of exhibiting a high extraction yield strength, while restraining an anchor length to a length as short as possible.;SOLUTION: An anchor preparation part is used for fixing earth retaining tension wires S1, S2 in an inside of a ground 10, and is constructed using a bearing pressure restraint tool 1. The bearing pressure restraint tool 1 includes a restraint tool body 2 provided with a delivery port 4A for delivering a grout injected from an injection rod 9, and a bag material F constrained by the restraint tool body 2. The bearing pressure restraint tool 1 is arranged in the inside of the ground 10, and the tension wires S1, S2 are hooked to a tension wire hooking member 52. The anchor preparation part is filled, in the bag material F, with the grout delivered from the delivery port 4A of the bearing pressure restraint tool 1, is diameter-enlarged up to an outside diameter larger than an inside diameter of a drilled hole 13 formed to arrange the bearing pressure restraint tool 1 in the inside of the ground 10, and is integrated with the restraint tool body 2 and the tension wires S1, S2 together with a solidified body of the filled grout.;COPYRIGHT: (C)2011,JPO&INPIT
