Abstract
An apparatus for forming embankments comprising a trapezium-shaped shield open at top and bottom and rearwardly. Material for the embankment is introduced into the top of the shield in slurry form and the difference in level between the slurry contained by the shield and the water outside the shield results in a force on the end wall of the shield. This causes the shield to travel end-wall first along the surface on which it is supported. As it moves forward, the shield will leave behind it an embankment formed to the same trapezium-shape as the shield itself. So that a layered form of embankment may be constructed, the shield may be fitted with a number of hoppers each associated with the formation of a particular layer.
