Abstract RU 2292262 C1

FIELD: construction.

SUBSTANCE: line comprises at least one concrete-placing machine and formwork made of pad and sides combined in a single chute system to form at least two adjacent long moulding spaces for construction articles. The concrete-placing machine has drive, receiving hopper mounted on the movable frame, control desk, and at least two feeders that underlay the outlet ports. Each of the feeders is provided with screw mounted in the housing provided with the slot overlapped by means of the pad in operation position. The length of the zone of additional mixing of the feeder screw is l = (1.5-5.0)L, where L is the maximum size of the cross-section of the receiving hopper in the direction of feeding of concrete mixture.
