REPAIR METHOD FOR EXISTING SPRAYED SLOPE
To provide a repair method for an existing sprayed slope that can suppress the generation of a large amount of industrial waste and shorten the construction period without the need to install a large-scale temporary protective wall, and can reduce the possibility of re-construction even if damage such as peeling/collapse or cracking of the spray surface due to deterioration or aging due to weathering, or due to natural disasters occurs.SOLUTION: A repair method for an existing sprayed slope comprises: a cleaning step S20 for cleaning the damaged existing sprayed slope; a spraying step S30 for constructing a sprayed slope by spraying an adhesive mortar on the existing sprayed slope after cleaning; a placing step S40 for placing reinforcing bars at predetermined locations on the sprayed slope; and a lining step S50 for covering a surface of the sprayed slope with a wire mesh body via the placed reinforcing bar, and then, holding the wire mesh body with a wire rope.SELECTED DRAWING: Figure 1
【課題】大掛かりな仮設防護壁の設置を必要とすることなく、大量の産業廃棄物の発生を抑えるとともに工期の短縮化が可能であり、風化に伴う劣化若しくは老朽化又は自然災害によって吹付面の剥離・崩落や、亀裂といった損壊が生じたとしても、再施工の可能性を低減することが可能な既設吹付法面に対する補修工法を提供する。【解決手段】損壊した既設吹付法面を洗浄する洗浄工程Ｓ２０と、洗浄後の前記既設吹付法面に対して接着モルタルを吹付けることで吹付法面を施工する吹付工程Ｓ３０と、吹付法面の所定箇所に補強鉄筋を打設する打設工程Ｓ４０と、打設した補強鉄筋を介し、吹付法面の表面を金網体で覆った後、ワイヤーロープにて金網体を拘持する覆設工程Ｓ５０とを備えた既設吹付法面に対する補修工法。【選択図】図１
