Abstract
The invention relates to a thin-walled centrifugal concrete pole manufacture method, which includes the steps: manufacturing a reinforcing rib framework, placing the reinforcing rib framework and stirred concrete into a centrifugal mould, rotating a centrifuge so that the concrete is uniformly distributed on the inner wall of the centrifugal mould to form a thin-walled centrifugal concrete pole wet green, taking the centrifugal mould down from the centrifuge, and solidifying the thin-walled centrifugal concrete pole wet green prior to steam curing and cooling demoulding. The method is characterized in that solidification of the thin-walled centrifugal concrete pole wet green is realized by leading a soft pressurizing membrane longer than the thin-walled centrifugal concrete pole wet green, made of plastics or rubber and provided with a media injection port into a central hollow cavity of the concrete pole wet green, adding pressurizing media so that the soft pressurizing membrane forms a closed cavity, keeping pressure of the pressurizing media until the concrete is solidified, emptying the pressurizing media, and taking the soft pressurizing membrane out prior to steam curing and cooling demoulding. The thin-walled centrifugal concrete pole manufacture method effectively avoids possibility of micro-cracks generated due to contraction distortion of the concrete for manufacturing a thin-walled concrete pole during solidification, so that the integral strength of the thin-walled concrete pole is improved.
