Installation Instructions

The connection techniques for HDPE double-wall bellows, together with b and c tubes, offer versatility with mechanical connections and a variety of thermal fusion methods. Among the primary options are butt fusion, electrical fusion, socket fusion, flange adapter connection, and compression connection, each ensuring robust and reliable joints tailored to your specific application needs.

1. For an earth arc-based pipeline setup, ensure stability with an appropriate base layer. Generally, a 100mm medium coarse sand layer should be placed on an undisturbed or compacted soil foundation. If the foundation soil is subpar, a two-layer sand gravel base of at least 200mm is recommended. The lower layer comprises 100-150mm gravel with a particle size between 5~32mm, topped by a coarse sand layer of at least 50mm. The base density must align with Table 2 standards. For soft soils, especially where foundation bearing capacity falls short of design requirements or is compromised by factors like construction precipitation, strengthen the foundation before proceeding. Once the specified bearing capacity is achieved, lay the medium coarse sand foundation layer to ensure enduring stability.

2. In the earth arc foundation's supporting angle zone, proper backfilling with medium coarse sand or gravel soil is crucial. Ensure the backfilling range covers the supporting angle 2α plus 30 degrees, adhering strictly to technical regulations on compactness to guarantee enhanced support and reliability.

3. As you lay the pipeline, dig grooves for the socket interfaces and sleeve connections accordingly. Adjust the groove's length, width, and depth to fit the pipe joint dimensions accurately. After completing the joint, promptly backfill with medium coarse sand to maintain structural integrity and long-term performance.

4. For pipeline sections susceptible to longitudinal uneven settlement, caused by shifts in pipeline load or ground soil changes, pre-emptively reinforce the foundation to avert potential issues and ensure a smooth, consistent pipeline installation.
In treating the foundation for polyethylene drainage pipes, opt for composite methods like sand pile or stone pile solutions. Avoid using rigid foundation treatments such as driven piles, concrete pads, or strip foundations to preserve flexibility and adaptability in your pipeline system.
