| 中文摘要: |
| 跨河倒虹吸采用围堰方案施工，不仅投资大进度慢，且涉及基坑排水、度汛等施工难题，往往成为工程实施的制约点.上饶市城市供水引水工程城西支线跨信江倒虹吸，全长582.00m 倒虹吸钢管采用沉管法一次性下沉安装成功，为工程节省了大量投资并缩短了工期，可为内陆地区类似跨河管道的设计及施工提供借鉴. |
| 英文摘要: |
| The cross-river inverted siphon is constructed by the cofferdam scheme，not only has a large investment and a slow progress，but also involves the construction problems of foundation pit drainage and flood season，which often becomes the restriction point for the implementation of the project.The inverted siphon across the Xinjiang river in the west branch of Shangrao city water supply and diversion project was successfully installed by sinking the 582m inverted siphon steel pipe in one time，which saved a lot of investment and time for the project，and provided valuable reference for the design and construction of similar river-crossing pipelines in inland areas. |
