REINFORCING STRUCTURE FOR BEDROCK SLOPE WITH LONG-TERM DURABILITY AND CONSTRUCTION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a reinforcing structure and a construction method thereof capable of not only ensuring a long-term durability by preventing toppling failures of a bedrock slope and landslides of a bedrock but reducing construction cost as using pressure plates is not needed.SOLUTION: A reinforcing structure is constructed by: arranging one or a plurality of reinforcing members 2 through one hole 1 or a plurality of holes 1 drilled across from a slope S to a moving bedrock region Gand immovable bedrock region G, each of which is longer than 5 m and equal to or less than 100 m; filling grout material 7 around the reinforcing member 2 in the drilled hole 1; and forming an anchoring zone for the reinforcing member 2 in both of the regions by curing the grout material 7.SELECTED DRAWING: Figure 1
【課題】岩盤斜面のトップリング崩壊や岩盤地ずべりを抑止して長期耐久性を確保することが可能で、また、受圧板を不要として施工コストの低減を図ることが可能な補強構造とその施工方法を提供する。【解決手段】斜面Ｓから移動岩盤区域Ｇ１および不動岩盤区域Ｇ２にかけて穿孔した１または複数の穴１に両区域に跨る長さ５ｍ超１００ｍ以下の長尺な補強材２を配置し、補強材２の周囲で穿孔した穴１にグラウト材７を充填し、グラウト材７の硬化により、両方の区域に補強材２の定着部を形成する。【選択図】図１
