PURPOSE:To control slipper resistance, and to obtain vibration-free effect as well as destruction preventing effect by separating the bottom part of a construction into a base side bottom and into a main body side bottom, the periphery between which is sealed, and by providing contact pressure adjustment ability in the gap of the contact surface. CONSTITUTION:In the center of a construction main body 1, a dry partition 4 is provided, and a water ballast 5 and a sand ballast 6 are impregnated or put into the outside thereof. Outer peripheries of a base side bottom 2 and of a main body side bottom 3 are sealed, and hydraulic pressure is applied to the gap of a contact surface. On a periphery of the base side bottom 2, an upright wall 9 is provided so as to form a certain gap between it and the main body 1, and an antishock device 11 is provided if necessary. A constant water level measure 51 is provided in the dry partition 4 of the main body 1, so as to control hydraulic pressure that works on the contact of both of the bottom 2, 3, via a heater pipe 52. The amount of leakage is supplied by a supply pump 53 through a supply pipe 54 to the constant water level measure 51, so as to maintain the water level, while the excessive water passing a dam 55 is sent back to the sea by an exhaust pit 56 through an exhaust pipe 58.
