摘要： A circular pipe member is penetrated into the seabed by a suction pressure, and a plurality of circular pipe members are vertically stacked thereon and integrated thereto to construct a cofferdam. When dismantling the cofferdam, the circular pipe members are disassembled and dismantled in order by using a lifting wire installed at a newly constructed structure installed in the inner space of the cofferdam.
