Abstract:
1. An apparatus for constructing an underground compacted, continuous filling wall and stratum structure in a slot excavation, the apparatus comprising: a chassis for transporting a means for constructing an underground compacted filling wall and stratum structure, the chassis movable along the length of a structure line in an intended advancing direction over the ground to form the structure which extends in that direction in a section of the slot excavation; a transportable framework mounted on the chassis and adapted to connect the chassis to the constructing means, support, dispose, and move the constructing means in the direction to form the structure; the constructing means comprising: where each of the number of the blades is capable of being forced into interaction with a filling of the section and with a front working face of the filling structure being formed in the section to force the filling and the face in a generally backward compressing direction that being opposite to the advancing direction, and to urge the rod digger in the advancing direction; where each of the number of the blades has a compacted filling structure-forming portion for forcing the filling in the generally backward direction and includes opposite cutting edge portions, a backward and toward the face-oriented ridge portion, and opposite gabble roof slopes—shaping, compressing slider facet portions; where the edge portions are operable to excavate the ground and the facet portions are operable to move the excavated ground earth in the generally backward direction, and to move the rod digger, with the blades, in the advancing direction relative to the filling being forced by the activating drive means capable of forcing the edge portions against a front working wall of the section and forcing the facet portions against the filling; so that the cutter bits and the edge portions excavate the ground, form the slot section, and fill the section with the excavated ground earth, and the opposite slope facet portions alternately compress the earth filling in the generally backward direction toward and on the face of the soil structure being formed in the advancing direction, and the rod is forced with the blades in the advancing direction by the resistance of the face to compression to assist the chassis and the framework to form a further section of the slot excavation being formed as the framework is transported in the advancing direction.
