<p><P>PROBLEM TO BE SOLVED: To provide a levee plastering machine by which the wear of a slope blade plate is reduced while keeping the effects for smoothening the slope of the levee, and in which a levee slope-smoothening body having a strength against the weight is installed. <P>SOLUTION: The figures express partial cross-sections representing positional relationships between contact extension lines Ma, Mb, and Mc, and a ring member 40 at the position from an extension part 22 of the slope blade plate 21 to a lower stage 23. The ring member 40 is positioned on the opposite side of a contact surface MS of the slope blade plate 21 based on the contact extension lines Ma, Mb, and Mc extended from the contact surface MS on the contact side of the slope blade plate 21 with the levee slope surface 70b over the position from the extension part 22 in the arc part 25 of the slope blade plate 21 to the lower stage 23. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
