Document Type and Number:
Japanese Patent JP2022113540
Kind Code:
A
Abstract:
To provide a cofferdam structure which can shorten assembly time of a cofferdam structure, and can prevent water leakage from a connection part between blocks.SOLUTION: A cofferdam structure includes a plurality of blocks 21 detachably connected to each other in a horizontal direction, and a vertical seal part 26 for covering a connection part 27 of the two blocks 21 adjacent to each other in the horizontal direction among the plurality of blocks 21 from one side of outside and inside, and water tightly sealing the connection part 27. The vertical seal part 26 includes two vertical seal fixing parts 262 which are detachably fixed to a side face on the one side of each of the two blocks 21 adjacent in the horizontal direction, and a vertical seal central part 263 which is continuous to the two vertical seal fixing parts 262 between the two vertical seal fixing parts 262, extends in a vertical direction and covers the connection part 27 from the one side, and has flexibility.SELECTED DRAWING: Figure 4
