AI Technical Summary
Existing steel cofferdam construction methods suffer from high construction difficulty, high cost, and poor stability in deep water and soft soil conditions. In particular, the steel pipe pile interlocking joint is prone to deformation, the steel sheet pile length is limited, and the steel sheet pile driving construction has high requirements, making them unsuitable for deep water environments.
The construction method of steel caissons to steel cofferdams is adopted, which optimizes the steel caisson structure into a driven steel cofferdam. The design head difference is reduced by water retention and pressure reduction, the bending strength requirement of the cofferdam wall is reduced, the number of walers is reduced, and a steel platform is erected on the steel platform to form a dry construction platform. The underwater concrete strip and the steel platform form an integral load-bearing structure.
It improves the applicability and efficiency of cofferdam construction in deep water and soft soil conditions, reduces construction costs, enhances structural stability and construction safety, and meets the requirements of green and environmentally friendly construction.
