SLOPE SPRAYING METHOD AND SLOPE REINFORCEMENT CEMENT-BASED HARDENED LAYER PROTECTIVE AGENT
To provide a slope spraying method that can sufficiently suppress damage such as cracking of a hardened cement layer provided for slope reinforcement.SOLUTION: The present invention provides a slope spraying method includes (1) (A) a step of spraying a cement-based spraying material after treating a surface of a target slope with a protective liquid ((A1) a pre-treatment step of the target slope with the protective liquid, and (A2) a step of spraying the cement-based spraying material on the surface after the pre-treatment may be included), and (B) a step of treating and curing a sprayed surface with a protective liquid to form a cement-based hardened layer, or a step comprising the steps (A1) and (A2); and a slope reinforcement cement-based hardened layer protective agent containing microfibrillar cellulose.SELECTED DRAWING: None
【課題】本発明は、法面補強のために設けられるセメント系硬化層のひび割れ等の破損を十分に抑制できる法面吹付工法を提供することを目的とする。【解決手段】本発明は、（１）（Ａ）対象法面の表面を保護液で処理後、セメント系吹付材を吹き付ける工程（（Ａ１）保護液による対象法面の前処理工程、及び（Ａ２）前処理後の表面にセメント系吹付材を吹き付ける工程を含んでもよい）、及び（Ｂ）吹付面を保護液で処理して養生しセメント系硬化層を形成する工程を含むか、又は、前記工程（Ａ１）及び（Ａ２）からなる工程を含む、法面吹付工法、及び、ミクロフィブリルセルロースを含む、法面補強セメント系硬化層用保護剤を提供する。【選択図】なし
