FIELD: civil engineering; production of construction mixes. SUBSTANCE: installation consists of movable frame with unbalance vibrators installed on bed frame on flexible supports. Main and additional guide columns are secured on bed frame posts. Guide columns are rigidly connected to each other in upper part. Main dispensing device for dry construction mix and additional dispensing device for spacing neutral separating mix are installed opposite to each other on bed frame. Vertically movable crossmember is installed on guide columns over replaceable formwork box. Crossmember is provided with forming device in form of cassette of holders lowered into formwork box through ports of driven rotary shutters engaging with upper end face of formwork box. Cross-section and height of each holder are equal to aperture of port one of shutters coaxial with holder and to height of wall of replaceable formwork box, respectively. Distance between holders and inner surfaces of walls of formwork box is 10-30 fold less than width of holders. EFFECT: increased capacity, reduced labour input and specific power intensity. 2 cl, 4 dwg
