INJECTION OUTER PIPE
To provide an injection outer pipe capable of preventing removal of a caulking member.SOLUTION: An injection outer pipe comprises: a cylindrical main body portion; a plurality of packers attached to an outer peripheral surface of the main body portion; an injection port provided between the neighboring two packers in the main body portion and making an inside communicate with an outside of the main body portion; a filling port provided in a part where the packers are attached in the main body portion and making an inside communicate with an outside of the main body portion; caulking units caulking end portions of the packers to the main body portion; and stoppers. The stoppers are fixed to the outer peripheral surface of the main body portion. The stoppers and the caulking units are arranged side by side in an axial direction of the main body portion.SELECTED DRAWING: Figure 1
【課題】かしめ部材が外れてしまうことを抑制できる注入外管を提供すること。【解決手段】注入外管は、筒状の本体部と、前記本体部の外周面に取り付けられた複数のパッカーと、前記本体部のうち、隣接する２つの前記パッカーの間に設けられ、前記本体部の内側と外側とを連通する注入口と、前記本体部のうち、前記パッカーが取り付けられた部分に設けられ、前記本体部の内側と外側とを連通する充填口と、前記パッカーの端部を前記本体部にかしめるかしめユニットと、ストッパーと、を備える。前記ストッパーは、前記本体部の外周面に固定されている。前記ストッパーは、前記本体部の軸方向において前記かしめユニットと並んでいる。【選択図】図１
