[0028] It is known that offshore floating bodies are engineering structures floating on the sea surface or submerged in seawater, which realize stable floating through the principle of buoyancy, and their design integrates fluid mechanics, material science and ocean engineering, and they are widely used in energy development, transportation logistics, scientific observation and national defense security fields. The following analyzes from four dimensions of technical principle, structure type, application scene and development trend: According to Archimedes' principle, the weight of the floating body displaces the weight of the sea water equal to its own gravity, so as to realize floating. For example, the ten-thousand-ton cargo ship reduces the overall density through the hollow structure design, so that the weight of the water displaced is equal to the total weight of the ship body, forming a buoyancy balance.

[0029] Stability design: the center of gravity is collinear with the center of buoyancy: when the floating body is tilted, if the metacenter (the intersection of the action line of buoyancy) is higher than the center of gravity, the gravity and the tilted buoyancy form a restoring moment, so that the floating body automatically returns to normal. Wind and wave resistance: offshore floating bodies need to withstand dynamic loads such as wind, waves, and currents. For example, the OFPV system in the North Sea area connects the modules through hinges, so that the floating platform can maintain structural integrity in storm surges (wave height 9~10 meters, wind speed exceeding 30.56 meters / second).

[0030] Material innovation: corrosion resistance: using alloy steel, glass steel or high-density polyethylene (HDPE) and other materials, and coating the surface with a corrosion-resistant coating to prolong the service life. For example, the offshore pipeline floating body is filled with polystyrene foam plastic inside and the outer layer is medium-density polyethylene, which can resist low-temperature attack and seawater corrosion. Lightweight and strength balance: steel materials achieve lightweight through reasonable structural design while meeting the load demand. For example, the super-large floating body module adopts a steel semi-submersible structure with a displacement of 500~200,000 tons, which can be assembled into an offshore airport or a floating logistics base.

[0034] A recess 21 is arranged at the center position of the upper surface of the concrete floating body 2, the lower end of the embedded steel barrel 1 is inserted into the recess 21, and a plurality of first stiffening ribs 11 are arranged on the outer wall of the lower end of the embedded steel barrel 1, each first stiffening rib 11 is inserted into the concrete floating body 2, preferably, the cross section of the embedded steel barrel 1 is a circular structure, each first stiffening rib 11 is uniformly distributed along the circumference, and the height of the first stiffening rib 11 is less than the height of the embedded steel barrel 1, so that the contact area between the embedded steel barrel 1 and the concrete floating body 2 can be increased by the first stiffening rib 11, and the stress can be better provided.

[0035] The prism mold 23 is provided with a second stiffening rib, it should be noted that the prism mold 23 is a standard part made of composite material, which improves the strength of the prism mold 23. During the pouring process of the concrete floating body 2, the prism mold 23 is placed at the designed position and can be used as a formwork inside the concrete floating body 2, so that a honeycomb can be formed inside the concrete floating body 2, the amount of concrete floating body 2 can be saved, and the prism mold 23 does not need to be taken out after pouring, which improves the processing efficiency of the concrete floating body 2.
