PURPOSE:To raise the workability of anchoring work by a method in which a solidifying material is packed into an anchoring pit, an anchor stresser is inserted into a sheath, and they are penetrated into the anchoring pit while charging the solidifying material into the sheath. CONSTITUTION:An outer solidifying material 5, e.g., concrete, etc., is packed into an anchoring pit A. A grout hose 4 and an anchor stresser 1 are inserted into a corrugated sheath 2 and the tip of the sheath 2 is positioned right above the pit A. An inner solidifying material 3, e.g., cement mortar, etc., is packed into the hose 4, during which period the tenser 1 and the sheath 22 are penetrated into the pit A. |
