ADHESIVE INJECTION METHOD AND ADHESIVE
PROBLEM TO BE SOLVED: To provide an adhesive injection method for injecting an adhesive between a structure and a reinforcement material and adhesive integrating them, capable of being conducted even in ultra low temperature environment at -25°C or lower, and the adhesive used in the injection method.SOLUTION: In an adhesive injection method for injecting an adhesive between a structure and a reinforcement material for reinforcement of the structure and adhesive integrating them, following processes are executed: an ordinary temperature A liquid generation process for stirring mixing a main agent and a curing agent to generate an A liquid containing them under an ordinary temperature environment at 0°C or higher; an ultra low temperature adhesive generation process for mixing the A liquid generated in the previous process and a B liquid containing an accelerator under ultra low temperature environment at -25°C or lower to generate the adhesive having viscosity under the ultra low temperature environment of 3000 mPa s or lower; and an ultra low temperature adhesive injection process for injecting the adhesive generated in the previous process between the structure and the reinforcement material by an injection device such as a pump or a squeeze pump under the ultra low temperature environment.SELECTED DRAWING: Figure 2
【課題】−２５℃以下となる極低温環境でも施工可能な構造物と補強材との間に接着剤を注入して接着一体化する接着剤注入工法及びその注入工法に用いる接着剤を提供する。【解決手段】構造物と、この構造物を補強する補強材とを、これらの間に接着剤を注入して接着一体化する接着剤注入工法において、０℃以上となる常温環境下において、主剤と硬化剤とを撹拌混合してこれらを含有するＡ液を生成する常温Ａ液生成工程と、−２５℃以下となる極低温環境下において、前工程で生成した前記Ａ液と、促進剤を含有するＢ液と、を混合させて、前記極低温環境下で粘度が３０００ｍＰａ・ｓ以下となる前記接着剤を生成する極低温接着剤生成工程と、前記極低温環境下において、前工程で生成した前記接着剤をポンプやスクイースポンプなどの注入装置で前記構造物と前記補強材との間に注入する極低温接着剤注入工程と、を行う。【選択図】図２
