Installation Instructions

The connection techniques for our innovative HDPE double-wall bellows and B and C tubes encompass a variety of mechanical and sophisticated thermal fusion procedures. Key methods include butt fusion, electrical fusion, socket fusion, flange adapter connection, and compression connection, ensuring a robust and durable assembly.

1. For optimal pipeline support, utilize an earth arc as the base. In cases of general soil quality, overlay the undisturbed soil foundation or compacted backfill with a medium-coarse sand base layer, 100mm thick, beneath the pipe. Should the foundation soil be suboptimal, employ a sand gravel base layer of no less than 200mm, potentially structured in two layers. The lower layer consists of gravel, sized 5~32mm, with a thickness of 100~150mm, while the upper layer is composed of coarse sand, no less than 50mm thick. Ensure the base density aligns with Table 2 guidelines. In scenarios of soft soil foundations, where bearing capacity falls short of design requirements or is affected by construction precipitation causing disturbance, initial reinforcement of the foundation is mandatory. Once the desired bearing capacity is achieved, proceed with laying the medium coarse sand foundation layer.

2. Within the earth arc's designed support angle, backfill axillary corners with medium coarse sand or gravel soil. The backfill scope should exceed the support angle 2α by at least 30 degrees, ensuring compactness meets technical regulation standards.

3. During pipeline setup, carefully dig grooves at the socket interface and sleeve connection points concurrently with pipeline laying. Determine groove dimensions by the pipe joint size, and once joint work is complete, promptly backfill with medium coarse sand to achieve necessary density.

4. When constructing sections prone to potential longitudinal uneven settlement due to pipeline load or ground soil alterations, fortify the foundation pre-laying to mitigate risks.
For the foundation treatment of polyethylene drainage pipes, employ composite methods like sand pile and stone pile treatments. Avoid rigid techniques such as driven piles, concrete pads, or concrete strip foundations, as they do not suit the flexible nature of this advanced drainage system.
