Installation Instructions

 

The connection modes of the HDPE double-wall bellows, as well as B and C tubes, are available in both mechanical and thermal fusion procedures. The primary connection techniques include butt fusion, electrical fusion, socket fusion, flange adapter connection, and compression connection. Each method ensures a robust and durable linkage, tailored for various installation requirements.

1. The pipeline should be based on an earth arc foundation. For standard soil quality, lay a 100mm thick medium coarse sand base layer on the undisturbed soil foundation or over a compacted backfilled foundation below the pipe base. If the foundation soil quality is inadequate, use a sand gravel base layer with a minimum thickness of 200mm. This can be laid in two layers: the lower layer comprises gravel with a particle size of 5~32mm and a thickness of 100~150mm, while the upper layer should be coarse sand with a thickness not less than 50mm. The base density must meet Table 2's specifications. For soft soil foundations where the bearing capacity is below design requirements, or if construction activities like precipitation disturb the original soil, strengthening the foundation first is essential. Once the required bearing capacity is achieved, lay the medium coarse sand foundation layer.

2. The axillary corner within the supporting angle range of the designed earth arc foundation must be backfilled with medium coarse sand or gravel soil. The backfill range should be no less than the supporting angle 2α plus 30 degrees, ensuring backfilling compactness meets technical regulations.
 

 

3. The grooves for the socket interface and sleeve connection in the pipeline foundation should be excavated concurrently with the pipeline installation. Determine the groove's length, width, and depth according to the pipe joint size. Upon joint completion, immediately backfill with medium coarse sand to ensure adequate density.

4. For sections where longitudinal uneven settlement may occur due to pipeline load and ground soil changes, reinforce the foundation prior to pipeline installation. This preemptive measure will mitigate potential settlement issues.
Opt for composite foundation treatment methods, such as sand piles or stone piles, for the polyethylene drainage pipe foundation. Avoid rigid foundation treatments like driven piles, concrete pads, and concrete strip foundations, as they are unsuitable for this application.
