However, when using this method, it is often difficult to coat the concrete on the outer wall of the corrugated pipe, making the production very troublesome. Moreover, the corrugated pipe is also difficult to fix, easily resulting in uneven distribution of the concrete on the outer wall of the corrugated pipe. To solve the deficiencies of the existing technology, we propose a concrete coating device for corrugated drain pipes. Summary of the Utility Model

A connecting hose 15 is arranged between the concrete injection port 8 and the upper coating mold 5. The connecting hose 15 can deform with the movement of the upper end of the upper coating mold 5. The connecting hose 15 connects the concrete injection port 8 and the upper coating mold 5. Two support columns 9 are also arranged between the top plate 6 and the base 1. The support columns 9 are used to support the top plate 6. Place the corrugated pipe on the upper end of the bottom coating mold 3. Then the upper coating mold 5 at the upper end moves downward through the cylinder 13. The upper coating mold 5 will be combined with the bottom coating mold 3. Then pour concrete into the concrete injection port 8. The concrete will enter between the upper coating mold 5 and the bottom coating mold 3 through the connecting hose 15 and coat the outer wall of the corrugated pipe. After the coating is completed, the cylinder 13 drives the upper coating mold 5 to move upward, and then the concrete drainage pipe can be demolded.

[0022] As Figures 1-4As shown, a core column 12 is provided at the front end of the side wall of the side plate 4. The corrugated pipe is sleeved and fixed on the outer wall of the core column 12.
