PURPOSE: A water barrier structure for constructing an underwater construction is provided to safely and conveniently define a work space for construction and to recycle the water barrier structure by blocking gaps on a duplex laminated structure. CONSTITUTION: A water barrier structure for constructing an underwater construction comprises a water barrier body(20), a bottom watertight sheet(30), and a connection watertight maintaining device(40). The water barrier body is composed by a lower water barrier frame(21) and an upper water barrier frame(22). The lower barrier frame is arranged on the underwater bottom. The upper water barrier frame is laminated and arranged on the lower water barrier frame by a connection frame(23). The bottom watertight sheet is installed on the lower water barrier frame and prevents water from flowing into a gap between the underwater bottom and the lower water barrier frame. The connection watertight maintaining device is installed on the water barrier body to preventing the water from flowing into a gap between the lower water barrier frame and the upper water barrier frame. |
