TEMPORARY COFFERDAM BODY, AND FORMING METHOD FOR CLOSED TYPE TEMPORARY COFFERDAM BODY

Japanese Patent JP2023159697

A

To provide a temporary cofferdam body and a forming method for a closed type temporary cofferdam body that enable both complete and partial closure of the surroundings of a weir and transmit an axial force caused by water pressure when closed and internally drained, in the circumferential direction.SOLUTION: In temporary cofferdam bodies 100, 200 constructed around a weir pillar 10, an upstream box body 20 and a downstream box body 30 are arranged around the weir pillar 10, there is a first gap 10a at a lateral side of the weir pillar 10, and the upstream box body 20 and the downstream box body 30 respectively comprise an upstream wall body 40 and a downstream wall body 50. By closing the wall bodies 40, 50, a closed type temporary cofferdam body 200 is formed. When the first gap 10a is closed, ends 42, 52 of the wall bodies 40, 50 are connected by a continuing member 80, and an axial force N caused by water pressure P acting on the temporary cofferdam body 200 by draining water between the temporary cofferdam body 200 and the weir pillar 10 is transmitted in the circumferential direction of the temporary cofferdam body 200 via the continuing member 80.SELECTED DRAWING: Figure 8B
