ABSTRACT:
A mobile cofferdam for use in the construction of elongated structures win a body of water is characterized by a water-tight rectangular shell which is guided and supported off the previously constructed segment of the sill or wall structure being built. The mobile cofferdam shell is floated into place, sunk, dewatered, and used as a cofferdam during construction of the sill. The mobile cofferdam is guided and supported off the previous placed concrete sill or wall and proceeds in a horizontal slip-form fashion. The walls of the mobile cofferdam are designed as spaced truss structures with skin plate on the inner, outer, top and bottom surface thereof to define a chamber which can be filled or evacuated with water to float the shell structure. The trailing end of the shell conforms to the sill or wall under construction and includes seals along the contact area for mating with the previously constructed sill portion.
