Abstract

PURPOSE: To simply and quickly level the surface of rubble layer over a wide range by a method in which a leveller weight placed on the surface of rubbele layer under water is vertically vibrated while moving it horizontally and the inclined angle and depth of the leveller weight are detected so as to control them constantly and also to maintain horizontal attitude at the bottom.
CONSTITUTION: A vibration type underwater rubble layer leveller 7 is hung down, and a leveller weight 8 is placed on the surface of a rubble layer 3 under water. When a driving motor is operated to vertically vibrate the leveller weight 8, the leveller weight 8 moves horizontally but the undulatory upside of the rubble layer 3 is inclined or changed in depth. The variations in the inclination and depth are detected from the inclined angle and projected amount of the projected portion out of the water surface of a manhole-like body 16. Then, the moving rate of the weight 12 and a tension acting on a wire 4 are controlled to control the depth and attitude of the weight 12.
