CONSTRUCTION METHOD FOR TEMPORARY FLOATING COFFERDAM

WIPO Patent Application WO/2014/156864

A1

A lower-most block (3) is connected on top of a base (5) while the base (5) is floating on water, and then sunk to a predetermined depth. Then, an upper block (3) is connected on top of the lower block (3) using a connecting structure (11) allowing for a predetermined amount of relative movement between the blocks in the horizontal direction and sunk to a predetermined depth, the abovementioned work process being repeated multiple times. Once all the blocks (3) are connected, a U-shaped rubber gasket (21) is set on an end part (17) of the temporary cofferdam structure (1) to form the temporary cofferdam structure (1). Next, the temporary cofferdam structure (1) is floated and towed in an upright state, and set on a wall surface (68) of a dam (69). A flap-type movable lid (6) is disposed on the top end (18) of the temporary cofferdam structure (1). Then, the interior space enclosed by the temporary cofferdam structure (1) and the wall surface (68) of the dam (69) is drained.
