Abstract
The invention is concerned with a method for continuous slide-casting of large-size concrete objects or corresponding elements for compacting high-viscosity casting mix. The slide-casting mould (33) comprises a bottom plane (34), side walls (38, 39) of the mould, as well as means (37) for pressurizing the casting mix mechanically. According to the invention, before the parallel side walls (44, 54) at the outlet end of the slide-casting mould (33), within the casting line concerned, walls or wall portions (40 to 43, 50 to 53) are provided as fitted to each other or to their corresponding portions, provided as pairs, as pivotable always in the same direction around substantially vertical shafts (45 to 49, 55 to 59) included in their planes. The moving parts of the side walls (38, 39) may be displaced in pairs in the lateral direction, relative the casting direction, e.g., by means of cylinder-piston devices (61 to 63). Thereat, repeated parallel dislocations back and forth are produced in the various regional zones of the mechanically pressurized high-viscosity casting mix (35) present in the slide-casting mould (33), and in particular in parallel dislocation planes of casting mix (3…
