Dust-proof membranes are provided across both ends of opposite respective divided surfaces defined by halves of wedge guide members. Each membrane has projections formed as an integral unit along the longitudinal side edges thereof. The projections are thrust into longitudinally extending C-shape cross-section grooves formed along the divided surfaces of the wedge guide members. The groove side surfaces are perpendicular to the bottom surface thereof.

Apparatus for mechanically breaking up rock

A paving material extrusion molding apparatus for continuously laying or molding a paving material wherein the paving material supplied into hoppers is conveyed into a molding element by a plurality of screw conveyors, the paving material is compacted or consolidated by screw thrusts equal to the frictional force produced by the dead weight of the extrusion molding apparatus, a reaction force created by the compaction or consolidation is utilized to float off the entire extrusion molding apparatus, and a reaction force created by the conveyance of the paving material being continuously fed serves to move the extrusion molding apparatus along the predetermined path.

Paving material extrusion molding apparatus

The paving material supplied into a hopper is conveyed by screw conveyors into a mold provided in the lower part of the apparatus thereby molding and laying the material. The paving material is densely compacted or consolidated in the mold, and when the paving material is conveyed under pressure further, the mold can be pushed up, and the reaction force of the conveying pressure acts to move the entire apparatus horizontally. Thus, structure having the same sectional shape as that of the mold can be formed and laid continuously on the ground.
