Tank allowing dry work for underwater framework for bridge construction and method of construction using that

摘要

The present invention is configured in a cylindrical shape, and is connected to a side wall composed of a predetermined height and a lower side of the side wall to be pivotable, and one side is connected to the side wall to pivot a plurality of sealing portions and sealing portions provided in a circumferential direction along the side wall. And, the other side includes a plurality of driving parts connected to one side of the sealing portion, the sealing portion is configured to be pivotable between the deployed position and the sealed position, and is configured to allow the foundation pile to pass inward from the deployed position, in the sealing position It relates to a lifting tank configured so that one side is in close contact with the outer surface of the foundation pile and the foundation method of the underwater bridge using the same. The underwater tank foundation construction method according to the present invention and the underwater bridge foundation construction method using the same are easy to install and remove on the foundation pile, and can be automatically ordered, thereby dramatically reducing the time and cost of creating the crane state can do. In addition, there is an effect to increase efficiency by minimizing underwater work when connecting between PC houses.
