The connection techniques for HDPE double-wall bellows and b and c tubes are multi-faceted, offering both mechanical connections and an array of sophisticated thermal fusion processes. Key techniques include the precision of butt fusion, the innovation of electrical fusion, the simplicity of socket fusion, the robustness of flange adapter connection, and the reliability of compression connection.
2. Within the support angle range of the designed earth arc foundation, the axillary corners must be filled with medium-coarse sand or gravel soil. This backfilling should extend beyond the support angle 2α by 30, ensuring compaction consistency as stipulated by technical regulations.
4. For pipeline sections susceptible to longitudinal uneven settlement due to load variations or ground soil changes, it is crucial to reinforce the foundation prior to laying the pipeline. This preemptive strengthening ensures durability and stability of the installation.
When treating the foundation of polyethylene drainage pipes, employ composite methods like sand or stone piles. Avoid rigid methods such as driven piles, concrete pads, or strip foundations to maintain flexibility and integrity.
