ABSTRACT:
A number of slot filling-compressing members are inserted from a framework into and across a slot-shaped excavation at ahead of a frontal face of a continuous, compacted slot filling being formed along the slot, and moved with a drive means connected to the members for intermittently forcing portions of the members against the filling to compress the filling adjacent to the members longitudinally against the face. The compacted filling is in this way formed by longitudinal pressure. The members can be mounted for forward or reciprocating movement in directions along and across the face.
