摘要
Provided are a prefabricated steel cofferdam with a single structure and a cofferdam construction method using the same. The prefabricated steel cofferdam includes: a lowermost cofferdam to which a plurality of lower caisson members having buoyancy bags mounted temporarily are assembled on the water; and upper cofferdams of one or two stages or more to which a plurality of upper caisson members are assembled on the water. The prefabricated steel cofferdam with a single structure and the cofferdam construction method using the same according to the present invention are easy to install and reinforce a structure, and can reduce a construction period of time, enhance safety and quality due to a precise construction not only on a solid ground but also on a weak ground, and enhance quality of the structure.
