Stop-water Structure Design of Shandong Haiyang Nuclear Power Plant Maritime Project

The stop-water design guarantees the construction quality and safety of dry construction cofferdam in the maritime project.The dry construction cofferdam of Shandong Haiyang Nuclear Power Plant maritime project is determined to apply the stop-water structure which combines the flexible diaphragm wall with high-pressure curtain grouting method.The above stop-water design is adopted firstly in the construction of a large maritime project,which play an important role in decreasing construction difficulty,shortening construction period and reducing cost.The project experiences may provide references for similar projects.
