SHEATH
To provide a sheath which has high positional degree of freedom when injecting a grout, less components, and preferable workability.SOLUTION: A sheath includes: a hollow cylindrical sheath body 10 in which a through hole 11 penetrating from an inner face to an outer face is formed on a peripheral face; and a tubular member 20 which is inserted into the through hole 11 and has one end 21 engaged with an inner edge of the through hole 11. Alternatively, a sheath includes: a hollow cylindrical sheath body 10 in which a through hole 11 penetrating from an inner face to an outer face is formed on a peripheral face; and a tubular member 20 inserted into the through hole 11, in which one end of the tubular member 20 has an enlarged diameter portion 23 which is enlarged outward in a radial direction and which is engaged with an inner edge of the through hole 11.SELECTED DRAWING: Figure 1
【課題】グラウトを注入する際の位置的自由度が高く、かつ、部品点数が少なく作業性が良好なシースを提供する。【解決手段】内面から外面に貫通する貫通孔１１が周面に形成された中空筒状のシース本体１０と、貫通孔１１に挿し込まれ、一端２１が貫通孔１１の内縁に嵌合する管状の管状部材２０と、を有する、あるいは、内面から外面に貫通する貫通孔１１が周面に形成された中空筒状のシース本体１０と、貫通孔１１に挿し込まれる管状部材２０と、を有し、管状部材２０の一端が、径方向外向きに拡径して貫通孔１１の内縁に嵌合する拡径部２３を有する構成とする。【選択図】図１
