Vertical vibrating pre-forming production process for large-diameter reinforced concrete drainage pipe

Abstract

The invention discloses a vertical vibrating pre-forming production process for a large-diameter reinforced concrete drainage pipe. A wet production process is adopted, pipe dies comprising a bottom die, an internal die and an external die are vertically stood on a ground or in a maintenance kiln, and an inserted vibration rod or an attached vibrator vibrates a concrete mixture in the pipe dies to pre-form the drainage pipe. The process comprises the steps of: manufacturing a reinforcement cage, mounting the reinforcement cage, cleaning the pipe dies, painting with a separant, assembling the pipe dies, stirring concrete, concreting, maintaining, de-molding and stacking. According to the production process, construction is facilitated, natural maintenance can be realized, energy sources can be saved, and industrial waste residues air-granulated steel slag can be used instead of yellow sand to reduce the discharge of the waste residues. Moreover, only about a half of equipment of a centrifugal process and a roller suspension process is adopted, so that more than a half of investment can be saved.
