Installation Instructions

The sophisticated connection methods for HDPE double-wall bellows, along with B and C tubes, encompass both mechanical linking and a sequence of advanced thermal fusion techniques. The primary modes include butt fusion, electrical fusion, socket fusion, flange adapter connection, and compression connection, ensuring a seamless and secure fit for optimal performance.

1. To establish a firm groundwork, the pipeline should rest on an earth arc. For standard soil quality, lay a foundational layer of medium coarse sand, 100mm thick, atop undisturbed soil or compacted backfill below the pipe's base. For subpar soil quality, consider a sand-gravel base layer at least 200mm thick, which may be layered: gravel at 5~32mm particle size, 100~150mm thick, beneath coarse sand no less than 50mm thick. Adherence to the density specifications of Table 2 is essential. In scenarios with a soft soil foundation, if the foundation's bearing capacity falls short of design expectations or is compromised by construction or precipitation, strengthen the foundation initially. Once the requisite bearing capacity is achieved, apply the medium coarse sand foundation layer.

2. Within the designed supporting angle range of the earth arc foundation, backfill the axillary corner with medium coarse sand or gravel soil. The backfilling area must exceed the supporting angle 2α by an additional 30, ensuring compactness aligns with technical regulation standards.

3. The pipeline foundation's socket interfaces and sleeve connections require precise groove digging as the pipeline is laid. Dimensions of these grooves—length, width, and depth—should align with the pipe joint size. Post-joint completion, promptly backfill with medium coarse sand to maintain appropriate density.

4. In regions susceptible to longitudinal uneven settlement due to pipeline load or ground soil variations, it is crucial to reinforce the foundation prior to pipeline installation, ensuring stability and longevity.
For polyethylene drainage pipe foundation treatment, adopt composite methods such as sand pile or stone pile techniques. Avoid using rigid measures like driven piles, concrete pads, or strip concrete foundations, which are unsuitable for this application.
