STONE WALL OR MASONRY WALL REINFORCING METHOD AND REINFORCING STRUCTURE
To provide a stone wall or masonry wall reinforcing method and reinforcing structure, which can exert a sufficient aseismatic reinforcing property by securely forming a cylindrical solidified layer body that is a uniform and high-quality reinforcing material without including an excavation process (without forming a borehole) even if a cobble stone layer consists of small gravels mixed with fine sediment.SOLUTION: A stone wall or masonry wall reinforcing method includes: a step to insert and position a hollow rod-like reinforcing member 1 on which a plurality of discharge holes 1a are provided in an axial direction into a joint part of a stone mounting layer 21 and remove a sediment component 13 on a circumference of the reinforcing member 1 by a water injecting means or an air blowing means that make use of the discharge holes 1a; a step to slide and set a cylindrical water permeable sheet 2 to the inside of the reinforcing member 1; and a step to form a cylindrical solidified layer body 9 to reinforce on a circumference of the reinforcing member 1 by injecting a solidification material 8 into the water permeable sheet 2 and oozing substantially uniformly the solidification material 8 oozed from the water permeable sheet 2 to the inside of the reinforcing member 1 to the outside through the discharge holes 1a.SELECTED DRAWING: Figure 3
【課題】栗石層が細かい土砂混じりの石礫で構成されている場合であっても、掘削工程を含まない（削孔を形成しない）で、均一で高品質な補強材である筒状固化層体を確実に形成することにより、十分な耐震補強性能を発揮することができる、石垣又は石積み壁の補強工法及び補強構造を提供する。【解決手段】軸方向に複数の排出孔１ａが設けられた中空棒状補強部材１を築石層２１の目地部に挿入して位置決めすると共に、排出孔１ａを利用して行う注水手段又はエアブロー手段により前記補強部材１の外周の土砂成分１３を除去する工程と、前記補強部材１の内部に筒状の透水性シート２を摺動させてセットする工程と、前記透水性シート２内に固化材８を注入し、前記透水性シート２から前記補強部材１の内側へ染み出した固化材８を排出孔１ａを通じて外部へ略均等に染み出させることにより、前記補強部材１の外周に筒状固化層体９を形成して補強する工程とを有する。【選択図】図３
