What is the production process of the reinforced concrete groove drainage pipe?
What is the production process of the reinforced concrete groove drainage pipe? The production process uses core mold oscillation. This process uses semi-dry rigid concrete. The vertical fabric inner mold oscillates and is radially kneaded. After molding, the inner mold oscillation force and amplitude are adjusted to compact the concrete with good oscillation force. Then, C50 high-strength pipe body concrete is obtained, which makes the pipeline's anti-load capacity and impermeability better than that of centrifugal and suspension roll processes. Together, the steel pipe reinforcement mesh of this process has a uniform protective layer, and the centrifugation and suspension roll process will not cause the displacement, jump bars, parallel bars, and loose bars of the reinforced wire network, which ensures the service life of the pipe for 50 years.
Because the vertical core mold oscillating tube manufacturing process uses two internal and external tube molds, the mold rigidity is very good and it is not easy to deform, and only one set of mold is required for one specification. Therefore, the roundness and tube diameter of the formed stern tube are standardized. There is no closing seam, and the smoothness of the inner wall of the tube has been significantly improved compared with the centrifugal process and the suspension roll process. In addition, the vertical core-mold oscillating pipe-making process re-rotates and kneads the concrete in the axial direction after the end of the concrete feeding, which more effectively increases the strength and straightness of the nozzle, and the construction device is smooth.
