Application of Composite Geomembranes in Dry Construction Cofferdam Project in Sea Area

The seepage prevention is the important and difficulty point in the design of dry construction cofferdam in sea area.At present,the large seepage prevention structure of cofferdam is usually constructed at land and the cost is high and construction period is long.The first successful application of composite geomembranes in large cofferdam shortens the construction period and reduces the project cost because it can be constructed under water together with the cofferdam structure.Which can be referred by the similar project.
