南线东段输送干管是白龙港片区最后1条输送干管,干管总长约26.1km,雨季输送流量约43.71m3/s。通过多方案比较,确定采用2根DN4000污水干管、全线不设倒虹深顶管的技术方案,既降低了污水输送能耗,又可每年节电约150万度。工程的实施,为今后污水长距离输送及超大口径顶管的设计施工积累了经验。
In the eastern section of the South Line, the main trunk pipe is the last trunk of the Bailonggang section, with a total length of about 26.1km and a transport flow of about 43.71m3 / s in the rainy season. Through multi-program comparison, it is determined that two DN4000 sewer pipelines will be adopted. There is no technical scheme for inverting the deep-seated pipelines in the whole line, which not only reduces the energy consumption of sewage transportation, but also saves about 1.5 million kilowatt-hours annually. The implementation of the project has accumulated experience in the design and construction of large-diameter sewage pipe jacking and long-distance sewage transmission in the future.
