Installation Instructions

 

The connection methods for HDPE double-wall bellows and b and c tubes encompass advanced mechanical connection techniques and a series of sophisticated thermal fusion processes. These premier methods include butt fusion, electrical fusion, socket fusion, flange adapter connection, and compression connection, ensuring seamless integration and unmatched durability.

1. The pipeline must be supported by an earth arc. For standard soil quality, a foundational layer of medium coarse sand, with a thickness of 100mm, should be laid on the undisturbed soil base or a backfilled, compacted foundation beneath the pipe's base. If the soil quality is subpar, a sand gravel base layer, no less than 200mm thick, is recommended. This can be constructed in two layers: the lower layer, consisting of 100-150mm thick gravel with a particle size of 5-32mm, and the upper layer, a coarse sand layer at least 50mm thick. The base density must adhere to the specifications outlined in Table 2. For soft soil foundations, if the bearing capacity is insufficient to meet design requirements, or if construction precipitation disturbs the original soil, thus compromising its bearing capacity, the foundation must be fortified. Once the specified bearing capacity is achieved, the medium coarse sand foundation layer can be laid.

2. The auxiliary corner within the support angle range of the designed earth arc foundation of the pipeline must be backfilled with medium coarse sand or gravel soil. The backfill region should extend at least the support angle 2α plus 30 degrees, with compaction adhering to technical regulation standards.
 

 

3. Grooves for the socket interface and sleeve connections in the pipeline foundation should be excavated concurrently with the pipeline laying process. The groove's dimensions-length, width, and depth-should correspond to the pipe joint size. After joint completion, promptly backfill the area with medium coarse sand to ensure optimal density.

4. In sections where longitudinal uneven settlement of the pipeline may occur due to factors such as pipeline load and soil changes, it is essential to reinforce the foundation before laying the pipeline.
For the foundation treatment of polyethylene drainage pipes, composite methods such as sand pile and stone pile should be employed. Rigid methods like driven pile, concrete pad, and concrete strip foundation are not suitable and should be avoided.
