To provide a water bottom leveling device using a grab bucket and a leveling tool as a weight while being connected to each other, which quickly adapts an inclination angle of a bottom surface of the leveling tool to the gradient of a leveling surface of an underwater riprap foundation, and can smoothly and quickly perform consolidation leveling work of the underwater riprap foundation.SOLUTION: A water bottom leveling device is configured to connect and integrate a grab bucket 3 which is suspended by a first suspending wire 25 and opens/closes a grab 9 with an opening/closing wire 31, and a leveling tool 4 having a bottom plate 43 having a flat lower surface, using a connection tool 42. The suspension posture of the water bottom leveling device suspended by the first suspending wire 25 can be changed between a horizontal posture in which the bottom plate 43 is horizontal and an inclined posture in which the bottom plate 43 is inclined to horizontal, with the connection part between the grab bucket 3 and the first suspending wire 25 as a supporting point. A support frame 41 of the leveling tool 4 is provided with a wire connection part 71 to which a second suspending wire 70 for changing the suspension posture is connected.SELECTED DRAWING: Figure 1
【課題】グラブバケットと均し具とを連結して重錘として使用する水底均し装置において、均し具の底面の傾斜角度を水中捨石基礎の均し面の勾配に素早く対応させて、水中捨石基礎の圧密均し作業をスムーズかつ迅速に行うことができるようにする。【解決手段】本発明の水底均し装置は、第１吊持ワイヤ２５で吊持され開閉ワイヤ３１でグラブ９が開閉されるグラブバケット３と、下面が平坦な底板４３とを備える均し具４とを連結具４２で連結して一体化することにより構成される。第１吊持ワイヤ２５で吊持された水底均し装置は、グラブバケット３と第１吊持ワイヤ２５の連結部分を支点にして、底板４３が水平となる水平姿勢と、底板４３が水平に対して傾く傾斜姿勢との間で吊持姿勢が変更できるようになっている。そして、均し具４の支持枠４１に、吊持姿勢を変更するための第２吊持ワイヤ７０が連結されるワイヤ連結部７１が設けられている。【選択図】図１
