PURPOSE:To mechanize the leveling operation for rubble-mound by a method in which a truck is movably supported on a body leg frame with expandible legs provided in the longitudinal direction of the rectangular frame and a raker and a tamping roller are also provided. CONSTITUTION:Two legs 6 each are expandibly provided to both sides in the longitudinal direction of the body leg frame of rectangular form, and a walking frame 12 is slidably coupled between the upper and medium stage side frames 5a and 5b of the frame 5. A rectangular frame 11 having similar arms 6 on its four corners is slidably coupled with the frames 12 and 5. Then, a raker 26 and a tamping roller 27 are provided to the front and rear sides of a truck 15 movably attached to the medium and lower stage side frames 5b and 5c of the frame 5 in such a way as to enable them to go up and down. Float tanks 34 are also provided to the front and rear sides of the frame 5 so that it can be towed and settled. Thereby, leveling work can be attained by turning the frame 5 horizontally at a given place and using the raker 26 and the tamping roller 27. |
