[0038] The building body 1 of the embodiment of the present application is fixed on the pile foundation 3 and will not be affected by the ocean current, thereby improving the stability of the building body 1. The pile foundation 3 has low requirements on water depth and geological strength, thereby reducing the dependence of the building body 1 on seabed conditions. The building body 1 is connected to the pile foundation 3 through the movable connection component 22 and the clamping component 23 to achieve the fixation of the building body 1, making the building body 1 more stable.

[0039] In one embodiment, in order to realize the movable connection between the movable connection component 22 and the pile foundation 3, the movable connection component 22 of this embodiment is sleeved on the pile foundation 3. A roller 221 is provided on the inner wall of the movable connection component 22, and the movable connection component 22 is movably connected to the pile foundation 3 through the roller 221, and the roller 221 rolls up or down along the pile foundation 3.

[0041] In one embodiment, after the building body 1 is moved to a predetermined position, in order to fix the building body 1, the clamping assembly 23 includes a clamping claw 231, which is rotatably connected to the connector body 21, and the limiting assembly 4 includes a limiting protrusion 41, and the limiting clamping claw 231 is clamped with the limiting protrusion 41. Specifically, one end of the clamping claw 231 can be rotatably connected to the connector body 21 through a bearing, and the clamping claw 231 can rotate around the bearing.

[0042] In one embodiment, in order to drive the claw 231 to move so that the claw 231 is engaged with the limiting protrusion 41, the engaging assembly 23 further includes a driving member 232 and a driving ring plate 233. The driving member 232 is connected to the driving ring plate 233, and the driving member 232 drives the driving ring plate 233 to move up and down, and the driving ring plate 233 is hinged to the claw 231. In one embodiment, the driving ring plate 233 and the claw 231 can be hinged through a fisheye joint. In the process of the driving member 232 driving the driving ring plate 233 to move downward, the driving ring plate 233 drives the claw 231 to rotate around the connection between it and the connector body 21. Preferably, the driving member 232 can be a hydraulic cylinder, and the driving shaft of the hydraulic cylinder is connected to the driving ring plate 233.

[0043] After the claw 231 is engaged with the limiting protrusion 41, in order to achieve the locking of the claw 231, a first fixing hole is provided on the driving ring plate 233, and the claw 231 is provided with a first fixing hole, and the driving ring plate 233 is detachably connected to the claw 231 through the first fixing hole and the second fixing hole.

[0044] In one embodiment, in order to achieve a sealed connection between the claw 231 and the limiting protrusion 41, a first sealing member 235 is provided on the claw 231, and the claw 231 is sealedly connected to the limiting protrusion 41 through the first sealing member 235. Preferably, the first sealing member 235 is a metal sealing ring, which contacts the limiting protrusion 41 through the metal sealing ring, thereby achieving sealing between the claw 231 and the limiting protrusion 41.

[0045] In order to achieve a sealed connection between the connector body 21 and the limiting protrusion 41, a second sealing member 236 is provided on the connector body 21, and the connector body 21 is sealed and connected to the limiting protrusion 41 through the second sealing member 236. Preferably, the second sealing member 236 is a rubber sealing ring. After the claw 231 is engaged with the limiting protrusion 41, the second sealing member 236 is squeezed, and the connector body 21 contacts the limiting protrusion 41 through the second sealing member 236 to achieve sealing.

[0046] In one embodiment, after the movable connection assembly 22 is sleeved on the pile foundation 3, the lowering of the building body 1 is achieved by ballasting. Therefore, a ballast tank 11 is provided at the bottom of the building body 1, and a water inlet 12 is opened on the building body 1, and the water inlet 12 is connected to the inside of the ballast tank 11.

[0047] Specifically, a plurality of ballast tanks 11 may be provided at the bottom of the building body 1, and the plurality of ballast tanks 11 are connected to each other through through holes 13, and the water inlet hole 12 provided on the building body 1 is connected to one of the ballast tanks 11. Seawater enters or is discharged from the ballast tank 11 through the water inlet hole 12. After the movable connection assembly 22 is sleeved on the pile foundation 3, the water inlet hole 12 and the through hole 13 may be opened to allow seawater to enter the ballast tank 11 through the water inlet hole 12. With the entry of seawater, the building body 1 slowly descends until it descends to the top of the limiting protrusion 41.

[0048] The building body 1 can be a double-layer structure, wherein the upper layer is the water traffic layer 14, and the lower layer is the underwater main layer 15, the water traffic layer 14 is connected to the underwater main layer 15, the water traffic layer 14 is located on the sea surface, and the underwater main layer 15 is located below the sea surface. The water traffic layer 14 and the underwater main layer 15 can be connected through elevators and stairs. The underwater main layer 15 can be used to build a submarine residence, including a bedroom, a dining room, a living room, and a bathroom. A material warehouse 141 and an equipment room 151 can be built on the water traffic layer 14.

[0049] In one embodiment, the underwater building further includes a helipad 5 and a pier 6, which are respectively located on the sides of the building body 1, and the helipad 5 and the pier 6 are both located on the sea surface. The water traffic layer 14 is connected to the helipad 5 and the pier 6, and the underwater building can be entered by helicopter or boat.

[0050] The construction method of the underwater building of this embodiment is:

[0051] First, the building body 1, connector 2, pile foundation 3, helipad 5 and pier 6 are prefabricated, and the connector 2 is connected to the outside of the building body 1. The connector body 21 can be a steel connector 2. Then, piles are driven on the seabed to erect the pile foundation 3 on the seabed. There can be multiple pile foundations 3, and the multiple pile foundations 3 are respectively erected at predetermined positions on the seabed, and the building body 1 is located between the multiple pile foundations 3. There can also be multiple connectors 2, and the multiple connectors 2 are respectively connected to the building body 1. Then, the movable connection component 22 of the connector 2 is sleeved on the pile foundation 3, the water inlet hole 12 is opened, and the building body 1 is lowered by ballasting. When the building body 1 is lowered, the roller 221 on the movable connection component 22 rolls along the pile foundation 3. When the connector 2 descends to the limit convex portion 41, it stops descending.

[0052] In the initial state, the claw 231 is in a horizontal state and is located below the driving ring plate 233. Then the driving member 232 is started, and the driving member 232 drives the driving ring plate 233 to move downward. The driving ring plate 233 drives the other end of the claw 231 to move downward, so that the claw 231 rotates around the bearing until the claw 231 is clamped on the limiting protrusion 41. The fixing of the building body 1 is achieved by the clamping of the claw 231 and the limiting protrusion 41 to prevent the displacement of the building body 1. After the claw 231 is clamped with the limiting protrusion 41, the driving ring plate 233 and the claw 231 are fixed by bolts 234, so that the driving ring plate 233 and the claw 231 are fixed together to achieve secondary locking. At this time, the building body 1 is fixed on the pile foundation 3 through the movable connection component 22, the claw 231 and the bolt 234.

[0053] Then, the pile cap is cast on the water traffic layer 14 and the pile foundation 3, and the prefabricated longitudinal beams, cross beams and panels are installed to complete the construction of the main building 1 and the traffic passages of the helipad 5 and the pier 6. Finally, the prefabricated helipad 5 and the pier 6 are transported to the site, the helipad 5 and the pier 6 are connected to the traffic passage, and concrete is poured at the connection to form a complete structure.

[0054] When the connector 2 needs to be repaired, the bolt 234 on the driving ring plate 233 is first removed, and then the driving member 232 is started, and the driving member 232 drives the hydraulic cylinder to move upward, and the claw 231 can be restored to a free state along the bearing. At this time, the connector 2 is restored to a temporary fixed state, which is convenient for underwater maintenance.

[0055] In one embodiment, a plurality of snap-fit ​​components 23 may be provided on each connector 2 , and snap-fitting is achieved through the plurality of snap-fit ​​components 23 and the limiting protrusion 41 .

[0056] The underwater buildings of the present application can be used in the fields of scientific research, tourism and energy development. In view of the defects of the anchoring method in that the geological conditions of the seabed are high and the building stability is poor, the present application fixes the building body 1 on the pile foundation 3, which will not be affected by the ocean current. At the same time, the pile foundation 3 has low requirements for water depth and geological strength. The construction conditions only need to meet the flat bottom, and can be built from shallow sea to island lagoon. In view of the defects of the gravity foundation method in that the ecological environment is affected, the underwater buildings based on the pile foundation 3 can be installed at any depth of water without sinking to the seabed, and have less impact on the seabed ecological environment.

Then, the driving member 232 is started, and the driving member 232 drives the driving ring plate 233 to move downward, and the driving ring plate 233 drives the claw 231 to move downward until the claw 231 is engaged with the limiting protrusion 41, and then the bolt 234 is used to fix the driving ring plate 233 and the claw 231.
