Installation Instructions

 

The connection modes of HDPE double-wall bellows and B and C tubes encompass both mechanical and thermal fusion procedures. Key modes of connection include butt fusion, electrical fusion, socket fusion, flange adapter connection, and compression connection, ensuring secure and reliable joints.

1. The pipeline shall be based on an earth arc foundation. For general soil quality, a 100mm thick layer of medium coarse sand should be laid on either the undisturbed soil foundation or a foundation with backfill compaction below the pipe's bottom. If the soil quality is poor, a sand gravel base layer at least 200mm thick can be used. This can be layered with the lower layer comprising 100-150mm thick gravel (particle size 5-32mm) and the upper layer being coarse sand with a thickness of at least 50mm. The base density must comply with Table 2 provisions. In cases of soft soil foundation, if the foundation's bearing capacity is less than design requirements, or if construction precipitation disturbs the bearing capacity, the foundation must be strengthened first. Once the specified bearing capacity is achieved, the medium coarse sand foundation layer is laid.

2. The axillary corner within the supporting angle range of the designed earth arc foundation for the pipeline must be backfilled with medium coarse sand or gravel soil. The backfilling range should be no less than the supporting angle 2α plus 30, and the backfilling compactness must comply with technical regulation provisions.
 

 

3. The grooves in the socket interface and sleeve connection within the pipeline foundation should be dug simultaneously with the pipeline laying process. The groove's length, width, and depth should be determined based on the pipe joint size. Once the joint is completed, the density should be backfilled with medium coarse sand immediately.

4. For sections where longitudinal uneven settlement of the pipeline may occur due to factors such as pipeline load and soil changes, the foundation should be reinforced prior to laying the pipeline.
Sand pile, stone pile, and other composite foundation treatment methods should be employed for the foundation treatment of polyethylene drainage pipes. Rigid foundation treatment measures such as driven piles, concrete pads, and concrete strip foundations are not recommended.
