- Abstract:
- Different from the conventional river sinking pipeline, the offshore sinking pipes are affected by the ebb and flow as well as waves at deep water and torrent. Especially when multiple pipes need to be sinked at the same time, the application process of more accurate positioning, as well as stable, fast and reliable operation is required. Double pipes and long-distance sinking pipeline technology were adopted in the temporary artificial island pipeline project at Zhuhai-Macao port of the Hong Kong-Zhuhai-Macao Bridge(HZMB). Comprehensive analysis and process control were made from pipe material selection, floating transportation and hoisting, trench excavation and backfilling. Finally, PE pipes were selected as sinking pipeline, and water test was completed on schedule, realizing the function of stable operation, which can provide reference for similar projects.
