[0002] The pipe segment is a prefabricated concrete steel bar with a certain curvature, which is mainly used in the construction of subways and highway tunnels. The pipe segment is cast by concrete in the production mold. Since concrete has a certain degree of collapse, the surface of the pipe segment is often uneven after the concrete is poured, so it is necessary to smooth the surface of the pipe segment after the mold is opened.

[0003] Before smoothing, the pipe segment needs to be cleaned of residual cement slurry on the edge of the mold; remove bubbles and impurities on the outer arc surface to ensure that the arc surface is flush with the arc edge of the mold side plate without large protrusions and depressions.
