1. Strictly control the quality of the raw materials of the corrugated culvert. The corrugated pipes entering the site should be stacked neatly, and workers are not allowed to step on the corrugated pipes.
2. The corrugated pipe culvert should be cut straight, and it is strictly forbidden to cut it into an oblique mouth.
3. The positioning of the corrugated pipe culvert should be accurate, especially near the joint. The spacing of the corrugated pipe culvert positioning steel bars is 0.5m, and none of them can be missing.
4. The method of connecting the corrugated pipe culvert: The corrugated pipe culvert joint is wrapped with a 0.3-meter-long large corrugated pipe, half-twisted at both ends, and there is no gap in the middle.
5. When the welded steel bar is close to the corrugated pipe culvert, measures should be taken to keep the corrugated pipe from being burned. If you are not careful, the burned area should be tightly wrapped with tape.
6. The corrugated pipe culvert should be covered and maintained to avoid premature aging due to wind and rain.
7. Considering the gradual decrease in the number of corrugated pipe culverts on the roof, all parts that conflict with the corrugated pipe culvert should avoid the corrugated pipe.
