摘要
A complete reinforcement cage is placed on the prodn. line, the concrete is poured, and the shutters are struck. The shutter assembly includes panels forming the internal (42) and external (51) wall faces. The reinforcement cage (10) is now rolled into position and the external end shutter is positioned. The unit is then pivoted to bring the open end (A) into a horizontal position. Once the initial concrete set has taken place the unit is pivoted back to the horizontal, the shutters are struck, and the precast box is rolled to the succeeding prodn. line station.
