Float above the sea or above the water, and tow it to the buried position in this floating state. Then the lid 70
Is gradually opened and seawater or water is introduced into the completed stepped cylinder 80, and the completed stepped cylinder 80 is sunk and buried in a predetermined position. In such a case, when the seabed or lake bottom is a relatively hard ground, the completed stepped cylinder 80 can be used in a state of being sunk to the seabed or lake bottom.

However, since this connecting cylinder overlaps the completed cylinder 60, the strength as a tunnel can be ensured. Therefore, in the illustrated example, only the connecting small cylinder 33 can be used if the strength at the time of transportation can be ensured.
