PROBLEM TO BE SOLVED: To provide a grout hose by which a small caliber drill pipe can be used and an execution cost can be reduced and provide an execution method of an anchor cable and the anchor cable using the hose. SOLUTION: The execution method is provided with a tendon, a sheath 22 covering the outer periphery of the tendon and constituting a free length part, a cutoff part formed in the boundary between the length part and the anchor length part where the tendon is exposed from the sheath 22, and a grout hose 30 bound with the tendon outside the sheath. The sectional shape of the ground hose 30 is made flat. By making the sectional shape of the grout hose 30 flat, the grout hose can be housed into a gap between the drill pipe 10 and the sheath 22. By using a small caliber drill pipe 10, a drilling diameter can be made small and the execution cost can be reduced. COPYRIGHT: (C)2004,JPO
