Installation Instructions

The HDPE double-wall bellows, along with b and c tubes, offer versatile connectivity options. These include a variety of mechanical connections and advanced thermal fusion techniques. The predominant connection methods encompass butt fusion, electrical fusion, socket fusion, flange adapter connection, and compression connection, ensuring a robust, leak-resistant join every time.

1. For the pipeline installation to achieve optimal stability, it should rest upon an earth arc base. In instances of typical soil conditions, a medium coarse sand base layer, 100mm thick, is recommended atop either undisturbed soil or compacted backfill beneath the pipe's base. Should the soil quality be subpar, a comprehensive sand gravel base layer, no less than 200mm thick, is advisable. This can be layered as follows: the lower layer consists of gravel, particle size ranging from 5 to 32mm, with a thickness between 100 and 150mm, topped by an upper layer of coarse sand at least 50mm in thickness. Base density must align with Table 2's standards. For foundations of soft soil where bearing capacity falls short of design requisites—due to factors like construction precipitation leading to soil disruption—it's paramount to consolidate the foundation. Once the specified bearing capacity is achieved, proceed to lay the medium coarse sand foundation layer seamlessly.

2. In constructing the designed earth arc foundation, any axillary corners within the supporting angle range must be meticulously backfilled using medium coarse sand or gravel soil. The backfill zone should extend beyond the supporting angle 2α by at least 30, and its compactness must adhere strictly to the technical regulations, ensuring structural integrity and longevity.

3. As part of the pipeline foundation process, grooves for socket interfaces and sleeve connections should be precisely excavated concurrent with pipeline laying. The dimensions of these grooves—length, width, and depth—should be tailored to the specific pipe joint size. Upon joint completion, it's crucial to backfill the density with medium coarse sand promptly to maintain the integrity and stability of the joint.

4. In areas where pipeline installation may encounter longitudinal uneven settlement due to variables like pipeline load and shifting ground soil, it is essential to reinforce the foundation prior to pipeline placement. This proactive measure ensures continued durability and functionality of the drainage system.
For the treatment of foundations supporting polyethylene drainage pipes, composite methods such as sand pile or stone pile are recommended. Rigid foundation treatments, including driven piles, concrete pads, and concrete strip foundations, should be avoided to maintain the flexible yet sturdy nature of the installation.
