The formation defect of corrugated pipe is mainly that the cement slurry is not filled with the entire corrugated pipe, resulting in a large crescent-shaped gap at the top of the corrugated tube, and even a phenomenon of dew. Another phenomenon is that the strength of the slurry is not enough to make the slurry, steel winch, and concrete
