INJECTION OUTER PIPE AND CHEMICAL FEEDING METHOD
To provide an injection outer pipe and a chemical feeding method capable of suppressing shrinkage of a packer.SOLUTION: An injection outer pipe includes a cylindrical body, a plurality of packers attached to an outer peripheral surface of the body, an injection port provided between the adjacent packers of the body so as to communicate an inside and an outside of the body, a filling port provided in a portion attached with the packer of the body so as to communicate the inside and the outside of the body, and a clamping unit for clamping an end of the packer to the body. The clamping unit includes a first clamping member, and a second clamping member located closer to a center in an axial direction of the packer than the first clamping member and having a width narrower than that of the first clamping member. A gap exists between the first clamping member and the second clamping member.SELECTED DRAWING: Figure 2
【課題】パッカーの収縮を抑制できる注入外管及び薬液注入工法を提供すること。【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を備える。前記かしめユニットは、第１のかしめ部材と、前記１のかしめ部材よりも、前記パッカーの軸方向における中央寄りに位置し、前記第１のかしめ部材よりも幅が狭い第２のかしめ部材と、を備え、前記第１のかしめ部材と前記第２のかしめ部材との間に隙間が存在する。【選択図】図２
