体構造物の建造方法を提來するものである。When roading a large floating structure that cannot be built at a dock, it is generally possible to first construct multiple floating structures, and connect each floating structure to 11 points on the water surface. The dose line is the connection between the two floating bodies below the water surface. Therefore, in the past, it was unthinkable to install a trunk to cover the pan of the abutting part under the water.
ca? In the configuration, the trunk is very long (for example, 1@
Qjll ~ 16Qjll), which makes it expensive, and because it is long, it is difficult to handle.
If an accident occurs in the trunk, there is a possibility that it will be difficult for the worker to escape. 5. Therefore, the present invention proposes a method of constructing a large floating structure that eliminates this problem at one point.
