Abstract
A method for levelling and filling a ditch is described, where a levelled layer of fine material is provided together with a contiguous layer of coarse material. A box-shaped device is described, having a height-adjustable rear end which when raised and lowered will determine the levelling height of the fine material which is in the box-shaped frame and exits therefrom below the raiseable and lowerable end wall when the box-shaped frame is moved through a ditch. Lateral projections on the end wall bring about a simultaneous dispensing/apportioning of coarse material along the side of the levelled layer of fine material. Whilst the box-shaped frame is moved forward and dispenses the layer of fine material, the side projections will deal with the dispensing/levelling of coarse material thrown thereon. The box-shaped frame has a roof having crossfall, which will guide the coarse material down to the side.The roof can be opened to allow the box-shaped frame to be filled with fine material.
