Reference numeral 60 is a mooring device such as a chain with an anchor attached to the base, and is used to moor the semi-submerged leisure facility E at a predetermined position.

Next, the floating and sinking process of the semi-submerged leisure facility E will be briefly explained with reference to FIGS. 3 and 4.

(a) Sedimentation process First, the base of the above-described floating body-attached supply and exhaust hose 70 is attached to the supply and exhaust valve 13 protruding from the upper surface of the upper structure 30, and then the floating body-attached supply and exhaust hose 70 is Valve 7
3 and the supply/exhaust valve 13 is opened, and the submerged body 10 is opened.
Open the water supply and drainage valve 12. Then, water is supplied from this water supply/drainage valve 12 into the airtight chamber 11 of the submerged body 10, and along with this water supply, the air that had been pressurized into the airtight chamber 11 of the submerged body 10 is passed through the supply/discharge valve 13. Hose 72 of the supply and exhaust hose 70 with floating body. Supply and exhaust valve 73. The submerged body 10 gradually loses its buoyancy and the half-submerged leisure facility E sinks.

Note that even if the top surface of the upper structure 30 is submerged due to the progress of sedimentation,
The supply/exhaust valve 73 of the supply/exhaust hose 70 with the floating body can be always positioned on the water surface by the floating body 71.

Of course, if this degree of subsidence is to control the stuttering of the semi-submerged leisure facility E, there is no need to attach the floating supply/exhaust bow 70 to the exhaust valve I3.

(b) Levitation process First, the free end of a hose (not shown) that communicates with a compressor (not shown) installed on land or on a ship is connected to the supply/exhaust valve 73 of the supply/exhaust hose 70 attached to the floating body. Supply and exhaust valve 7 of supply and exhaust hose 70 with floating body
3. Confirm that the supply/exhaust valve 13 is open, and also confirm that the supply/discharge valve 12 of the submerged body 10 is open. Thereafter, the compressor (not shown) is operated to forcefully send pressurized air (10) into the airtight chamber 11 of the submerged body 10. Then, the water in the submerged body 10 is drained by this pressurized air through the water supply and drainage valve 12, and the submerged body 10 gradually gains its buoyancy, and the semi-submerged leisure facility E floats up.

When the water in the semi-submerged leisure facility E reaches a predetermined position, the supply and exhaust valve 73 of the supply and exhaust hose 70 with the floating body
．． Said supply/exhaust valve 13. The water supply and drainage valve 12 of the submerged body 10 is tightened, and the free end of the hose communicating with the compressor is removed from the supply and discharge valve 73.

〔Effect of the invention〕

As described above, the present invention includes a submerged body, a support cylinder erected at intervals on the submerged body, and an upper structure attached to the support cylinder, and the submerged body has an internal structure. An airtight chamber is formed in the airtight chamber, and a water supply and drainage valve communicating with this airtight chamber is provided to enable water supply and drainage, and a swimming space that opens upward and downward is formed inside the upper structure, so that the sea,
By simply mooring this semi-submerged leisure facility to a lake or river, it can be used as a leisure facility such as a swimming facility, a fishing pier, or a fish farming facility, and also has the following effects. In other words, (1) As mentioned above, this semi-submerged leisure facility is constructed by attaching the upper structure to the top of support cylinders that are erected at intervals on the submerged body. When the type leisure facility is floated so that the upper structure is exposed above the water surface, the water-swallowing part can be made into a support cylinder erected at a distance from the submerged body.

As a result, the flood area can be significantly reduced compared to the superstructure, and the shaking of the semi-submerged leisure facility due to waves can be greatly alleviated. Because the wave transmitting structure consists of a body, the influence of currents such as tidal currents can be greatly alleviated.

(2) The submerged body of the half-submerged leisure facility has an airtight chamber inside, and a water supply and drainage valve communicating with this airtight chamber is installed to enable water supply and drainage. By supplying water or draining the supplied water, this semi-submerged leisure facility can be made to float or sink freely. As a result, not only can the water line be adjusted as necessary, but also the half-submerged leisure facility can be submerged underwater during stormy weather, and the half-submerged leisure facility can be moved away from its construction site. It can be easily towed to a floating location.
