RIPRAP LEVELING DEVICE
To provide a riprap leveling device which can efficiently press riprap in the water without displacing a construction position.SOLUTION: A riprap leveling device includes a guide shaft 10, and a leveling weight 20 which has a through hole 28 for inserting the guide shaft 10 therethrough and is movable in a longitudinal direction of the guide shaft 10. From states where an end E on a lower side of the guide shaft 10 hung by a first wire W1 of a crane is arranged at a position in contact with riprap S in the water and a lower surface 22A of the leveling weight 20 hung by a second wire W2 of the crane is arranged on an upper position of the riprap S, the second wire W2 is loosened, the leveling weight 20 is lowered along the guide shaft 10 by the gravity, and the lower surface 22A comes in contact with and presses the riprap S in the periphery of the guide shaft 10.SELECTED DRAWING: Figure 1
【課題】施工位置がずれることなく効率的に水中の捨石を押圧することができる捨石均し装置を提供する。【解決手段】ガイド軸１０と、ガイド軸１０が挿通された貫通穴２８を有し、ガイド軸１０の長手方向に沿って移動可能な均しウエイト２０と、を備え、クレーンの第１のワイヤＷ１で吊り下げられたガイド軸１０の下側の端部Ｅが水中の捨石Ｓと接する位置に配置され、クレーンの第２のワイヤＷ２で吊り下げられた均しウエイト２０の下面２２Ａが捨石Ｓより上方の位置に配置された状態から、第２のワイヤＷ２が緩められて、均しウエイト２０が重力によりガイド軸１０に沿って降下して、下面２２Ａがガイド軸１０の周囲の捨石Ｓに当たって押圧する。【選択図】図１
