Abstract:
1. An excavator for constructing an underground continuous, compacted filling wall, the excavator comprising: a transporting chassis movable over the ground along the length of a line of the wall in a direction to produce the wall in a trench which extends in that direction; a supporting framework mounted on the chassis and adapted to be transported in the direction to produce the wall; an endless linear motive member and a number of cutter and compactor slider members arranged on the endless member to form a linear digger adapted to extend down into the ground from the framework; a means supporting the motive member on the framework for longitudinal movement in intended and predetermined compacting directions crossing the advancing direction along a front working face of the wall; a drive means for producing the longitudinal movement in the intended and predetermined compacting directions so that wall-compacting facet portions of each of the compactor members compact the filling generally toward and on the face as the framework is transported in the advancing direction.
