The application of Steel-concrete combined cofferdam in complex construction environment

摘要

Steel-concrete combined cofferdam is a new type of cofferdam, which combines the characteristics of steel cofferdam and concrete cofferdam, and has many advantages, such as higher construction speed, lower cost, etc. In this paper, the application of Steel-concrete combined cofferdam in the foundation construction of a bridge in Nanjing was introduced. The construction experience of this cofferdam in complex environment can provide useful reference to similar engineering.
