摘要
PURPOSE: A prefabricated cofferdam block for river construction and a construction method of a cofferdam using the same are provided to repetitively use a cofferdam by easily separating the cofferdam. CONSTITUTION: A prefabricated cofferdam block(10) for river construction comprises a base block(110), a vertical block(120), a protrusion(121), a coupling groove(122), end protrusions(112), and inlets(111,123). The vertical blocks are vertically extended from the top surface of the base block. The protrusion and the coupling groove are formed in the vertical block. The end protrusions are formed on the bottom surface of the base block. The inlets fill a space formed inside the vertical block and the base block with water.
