PROBLEM TO BE SOLVED: To provide a water cut-off liquid mixing injection system which can reduce clogging of a member composing the water cut-off liquid mixing injection system with a cured material and which allows easy removal and cleaning of the cured material even when the clogging occurs.SOLUTION: A water cut-off liquid mixing injection system comprises: two tanks Tand Tfor storing two respective water cut-off liquids; high-pressure pumps Pand Pconnected to the respective tanks, for supplying the two respective water cut-off liquids; an injection tool 10A for causing the two water cut-off liquids supplied from the high-pressure pumps to join and injecting them; and a water cut-off liquid mixing injection plug 34 for agitating and mixing the water cut-off liquids caused to join by the injection tool and injecting them into a water leakage part in a cement-based composition body structure. The injection tool 10A has a junction head 11 for causing the two water cut-off liquids to join. A mixer for agitating and mixing the two water cut-off liquids is built into the water cut-off liquid mixing injection plug 34. The junction head 11 of the injection tool is connected by connection means which can separate the water cut-off liquid mixing injection plug 34 while leaving it in the water leakage part.SELECTED DRAWING: Figure 1 【課題】止水液混合注入システムを構成する部材に硬化物が詰まるのを軽減し、詰まっても簡単に除去及び清掃ができる止水液混合注入システムを提供する。【解決手段】二止水液をそれぞれ貯留する二つのタンクＴ１、Ｔ２と、各タンクに接続されて二止水液をそれぞれ供給する高圧ポンプＰ１、Ｐ２と、高圧ポンプから供給された二止水液を合流させて注入する注入具１０Ａと、注入具で合流された止水液を撹拌・混合してセメント系組成体構造物の漏水箇所へ注入する止水液混合注入プラグ３２を備え、注入具１０Ａは、二止水液を合流させる合流ヘッド１１を有し、止水液混合注入プラグ３４は、内部に二止水液を撹拌・混合するミキサーが内蔵されており、注入具の合流ヘッド１１は、止水液混合注入プラグ３４を漏水箇所に残したまま分離可能な結合手段で結合されている。【選択図】図１
