HDPE二重壁コルゲートパイプ設置ガイドライン

HDPE Double-Wall Corrugated Pipes Installation Guidelines

1. Trench Requirements

Prepare a trench that is wider than the pipe diameter and deep enough to provide adequate cover. The bottom should be level and free of sharp objects.

2. Pipe Inspection

Inspect the pipes for any visible damage before installation. Check for cracks, deformations, or any irregularities that could affect performance.

3. Pipe Placement

Carefully place the pipes in the trench, ensuring they are not dropped or dragged. Maintain proper alignment to facilitate seamless flow and prevent blockages.

4. Proper Backfilling

After placing the pipe, backfill with suitable material in layers. Compact each layer properly to prevent settling and ensure the stability of the pipe.

5. Final Checks

Once installation is complete, conduct a final inspection to ensure all joints are secure and the pipe is properly aligned. Test the system if necessary to confirm there are no leaks.
