INJECTION OUTER PIPE AND CHEMICAL FEEDING METHOD
PROBLEM TO BE SOLVED: To provide an injection outer pipe capable of being prevented from coming out, when an unimproved area on a ground side with respect to an area constructed by a chemical feeding method is excavated by construction machinery such as a backhoe, and the chemical feeding method.SOLUTION: In an injection outer pipe (1) of the present invention for use in a chemical feeding method, a part (1-2) (of the injection outer pipe) embedded and left in an unimproved area (R2) is made of a material (e.g. paper: a material with shear strength low enough to be cut with a bucket cutting edge of a backhoe).SELECTED DRAWING: Figure 6
【課題】薬液注入工法を施工した領域よりも地上側の未改良領域をバックホウ等の建設機械で掘削した際に、注入外管が抜け出してしまうことを防止することが出来る注入外管及び薬液注入工法の提供。【解決手段】本発明の注入外管（１）は、薬液注入工法で使用される注入外管において、未改良領域（Ｒ２）に埋め殺される（注入外管の）部分（１−２）をせん断強度が小さい材料（例えば紙：バックホウのバケット刃先で切断される程度のせん断強度の材料）で構成した。【選択図】図６
