To provide a masonry reinforcement method for filling grout without adding a grout injection pressure to stacked stones of a masonry construction when injecting the grout.SOLUTION: In an association portion where joints between stacked stones of a masonry construction associate, an injection hole penetrating a joint end of each stacked stone being in contact with the association portion is drilled. In a joint back filling step, a flexible nozzle tube is inserted from the injection hole along an association joint without sealing the association joint, grout is injected into a joint back from a tip of the nozzle tube to fill the grout into a joint back space, the tip of the nozzle tube is gradually moved backward, and the grout is filled along the joint to the vicinity of the injection hole. The joint back filling step is performed to all of the association joints that are connected with the injection hole. Then, in an entrance filling step, the grout is injected into a space around an entrance of the injection hole to fill and the nozzle tube is pulled out. The above works are sequentially performed to all of the drilled injection holes.SELECTED DRAWING: Figure 1
【課題】グラウト注入時に石積み工の積石にグラウト注入圧が加わることなく充填を行う石積み補強工法の提供。【解決手段】石積み工の各積石の間の目地が会合する会合部に、該会合部に接する各積石の合端を貫通する注入孔を穿孔する。そして、注入孔に対し、会合目地をシールぜず注入孔から会合目地に沿って可撓性のノズルチューブを挿入し、ノズルチューブ先端から目地裏にグラウトを注入し目地裏空間にグラウトを充填しつつ、ノズルチューブの先端を漸次後退させ、注入孔近傍まで目地に沿ってグラウトを充填する目地裏充填工程を、該注入孔に接続するすべての前記会合目地に対して行い、その後、該注入孔の入口周囲の空間にグラウトを注入し充填し、ノズルチューブを抜脱する入口充填工程を行う、という作業を、穿孔されたすべての注入孔に対し順次行う。【選択図】図１
