To provide a jack cover with an excellent function of preventing deformation of a jack, which includes a function of adjusting an inner space dimension vertically.SOLUTION: The jack cover of the present invention is a jack cover protecting a jack that interposes between two strut materials supporting lateral pressure of earth-retaining walls facing each other in an earth-retaining structure, the jack cover comprising an upper cover and a lower cover. The upper cover has an upper base part whose bottom surface contacts the upper surfaces of the two strut materials, and upper side parts extending downward from both sides of the upper base part. The lower cover has a lower base part whose upper surface contacts the bottom surfaces of the two strut materials, and lower side parts extending upward from both sides of the lower base part. An inner space dimension in the vertical direction is defined between the bottom surface of the upper base part and the upper surface of the lower base part, and it is possible to adjust the inner space dimension in the vertical direction by fastening the upper side parts and the lower side parts with fastenings.SELECTED DRAWING: Figure 1

    【課題】鉛直方向の内空寸法調整機能を備えた、ジャッキの変形防止機能が高いジャッキカバーを提供すること。【解決手段】本発明のジャッキカバーは、山留構造において、対向する土留め壁の側圧を支持する2本の切梁材の間に介在するジャッキを保護するジャッキカバーであって、上カバーと下カバーとを備え、上カバーは、底面で2本の切梁材の上面に当接する上ベース部と上ベース部の両側から下方に延出する上サイド部とを有し、下カバーは、上面で2本の切梁材の底面に当接する下ベース部と下ベース部の両側から上方に延出する下サイド部とを有し、上ベース部の底面と下ベース部の上面の間に鉛直方向の内空寸法を定義し、上サイド部と下サイド部とを締結具で締結することで鉛直方向の内空寸法を調整可能であることを特徴とする。【選択図】図1
