FIELD: technological processes.
SUBSTANCE: invention relates to apparatus (1) for casting a concrete article in a mould. Apparatus (1) comprises container (2) for a concrete mixture, nozzle (3) and shutter member (4). Container (2) movably mounted above the mould. Nozzle (3) is attached to the bottom of said container (2) and is intended to feed the concrete mixture from said container (2) into the mould. Shutter member (4) can move vertically and can pass through said container (2) into said nozzle (3). Width of said nozzle (3) in a first horizontal direction is much larger than the width of the nozzle in a second horizontal direction. Said second direction is perpendicular to said first direction. Said container (2) for concrete mixture is pivotable about its vertical central axis to change the nozzle orientation during the casting process.
EFFECT: higher efficiency of filling narrow gaps that remain in the mould, while maintaining capacity and constant filling speed.
