摘要
在临港工业区DN1400供水管道穿越海河工程中,采用牵引沉管技术进行了河底穿越(倒虹管)施工,对钢管进行整体焊接、防腐、拼装后浮运至管槽水面,然后充水下沉安装就位。详细介绍了施工方法及具体技术措施,可供相关工程参考。
In the Haihe River crossing project of DN1 400 water supply pipeline in Lingang Industrial Area, the immersed tube traction technology （ inverted siphon） was used. After welding, anti-corrosion and assembling on the riverside, the steel pipe was floated into over the trench, and water was filled in the pipe to make it sink down to the trench. The construction method and the concrete technical measures are introduced, which can provide a reference for the relevant works.
