うことができる。That is, the present invention allows a multi-broken anchor bolt installed in hydroxyl to be placed in a floating position underwater via a buoyant tank at the top of four keys, and is housed in this underwater structure. Using the attached underwater TV camera, we confirmed the relative position of the bolt hole drilled in the water jet 4 and the anchor bolt, and confirmed that the underwater 1st construction iC was located at the jet no X''.
Correct the position of the skin by the action of ~ and correct the horizontal force position by the action of the jacking device installed at the base.
When the bolt hole is connected to the anchor bolt, it is underwater.
This provides a method for installing J relics underwater, which involves lowering the relics, and then attaching a nut that fits the anchor points (1#c4). According to this construction method, the relative position of the anchor bolt and the bolt hole is always checked using an underwater television camera, and it is possible to adjust the slight positional deviation in the horizontal direction and circumferential direction and attach the sub-position. Compared to the conventional method of suspending with a 70-inch crane, it is possible to carry out sub-attaching in a safer and more efficient manner.
