    • The present invention relates to a device and method for levelling an open asphalt structure in hydraulic engineering works. The invention particularly relates to a device which is provided at the rear with a driven, substantially smooth roller (8) as propelling element and provided at the front with one or more driven levelling shafts (3,3') provided with radially placed levelling blades (13,13'). The levelling shafts are provided on the outer ends with a height-adjustable asymmetrical support element (4,5), on one side a rotating element (5) and on the other a sliding element (4). The invention also relates to a method for levelling and open asphalt structure in hydraulic engineering works by means of the described device, wherein adjacent asphalt strips are laid by providing the sliding support element on an already asphalted strip and providing the rotating element on the surface still to be asphalted.
    • 本发明涉及一种在水利工程中对开式沥青结构进行整平的装置和方法。 本发明特别涉及一种在后部设置有驱动的,基本平滑的作为推进元件的滚子(8)并在前面设置有一个或多个驱动的调平轴(3,3')的装置,该驱动的调平轴(3,3')设置有径向放置的调平叶片 (13,13' )。 调平轴设置在外端,高度可调的不对称支撑元件(4,5),一侧是旋转元件(5),另一侧设置有滑动元件(4)。 本发明还涉及一种通过所述装置在水力工程工程中调平和打开沥青结构的方法,其中通过在已经沥青的带上提供滑动支撑元件并在表面上提供旋转元件来铺设相邻的沥青条 要沥青
