Installation Instructions

The connection modes of HDPE double-wall bellows and b and c tubes encompass both mechanical and thermal fusion techniques. Key methods include butt fusion, which ensures seamless joints, electrical fusion for precision connectivity, socket fusion for swift assembly, flange adapter connection for robust setups, and compression connection, ensuring secure and leak-proof installations.

1. The pipeline should rest on an earthen arc. For general soil conditions, a medium coarse sand layer, 100mm thick, needs to be laid on undisturbed or compacted soil below the pipe base. In areas with poor soil quality, opt for a sand gravel base of at least 200mm thickness, potentially in two layers: the lower consisting of gravel (5~32mm particle size) 100~150mm thick, and the top layer being coarse sand of at least 50mm. The density must adhere to Table 2. In soft soil scenarios, where the foundation's bearing capacity is inadequate or disturbed, it is crucial to reinforce the foundation first. Once the target bearing capacity is achieved, lay the medium coarse sand foundation layer.

2. The axillary corners within the pipeline's designed earth arc foundation's support angle range must be backfilled with medium coarse sand or gravel soil. This backfill should not be less than the support angle 2α plus 30, ensuring the compactness aligns with the technical regulations.

3. As the pipeline is laid, dig grooves at the socket interface and sleeve connections in the foundation. These groove dimensions (length, width, depth) should match the pipe joint size for precision. After joint completion, promptly backfill with medium coarse sand for optimal density.

4. For areas prone to longitudinal uneven settlement due to load or soil changes, reinforce the foundation prior to laying the pipeline to ensure stability.
Employ composite foundation treatment methods like sand pile and stone pile for polyethylene drainage pipe foundations. Avoid rigid measures such as driven piles, concrete pads, or strip foundations to maintain flexibility and integrity.
