- Title:
- Design and Research on Sinking Pipeline Technology of Artificial Island at Zhuhai-Macao Port of HZMB
- 摘要:
- 区别于常规内河沉管，海上沉管受涨落潮及风浪影响，流急水深，尤其是需要同时沉放多根管道时，要求采用定位准确、稳定快速、运行可靠的敷管工艺。港珠澳大桥珠澳口岸人工岛临时管线上岛工程采用双管道、长距离沉管技术，从管材选择、浮运吊装、沟槽开挖及回填方面进行了较为全面的论证分析和过程控制，最终选择PE管作为沉管管材，并按计划完成了通水试验，实现了稳定运行，可为同类工程提供借鉴。
- 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.
