ABSTRACT:
A device for backfilling a trench from spoil left alongside it comprises a forecarriage (7) and a main frame (10). The former comprises means (12) for positioning it centrally in the trench (3). The latter is located behind the former and carries one or more angled blades (9) and lateral stabilizers (18,19) adapted to contact the ground outside the spoil.
The device is towed rather than pushed and if a long tow-rope is used a pipeline can be trenched and the trench backfilled in a single traverse.
