Detailed implementation manners

[0015] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings. This embodiment does not constitute a limitation to the present invention. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of this application.

[0016] A fish tank aquaculture platform in a marine ranch, as Figure 1 shown, includes a fish tank main body with a total length of 53.00 m and a molded breadth of 24.00 m. The fish tank main body is composed of four platform structures with elevations of 3.5 m, 12 m, 15 m, and 21 m connected and combined with each other. Each platform structure mainly consists of structural panels, longitudinal girders, sectional panel frames, deck structures, equipment and foundation pads, outfitting parts, etc. Each platform structure includes several sectional structures, and the sectional structures are connected to each other.

[0017] In this embodiment, the four platform structures are in sequence as Figure 2 shown, the first layer is the T0 area (bottom floating tank layer). The bottom floating tank layer is arranged in a surrounding manner (in a "day" shape) and divided into 7 sections: BS1C / BS2C / BS3C / BS1P / BS1S / BS3P / BS3S. BS1C and BS3C are two pairs of ballast tanks at the head and tail ends, BS2C is a pair of pump rooms in the middle (which can be equipped with fire pumps, ballast pumps, seawater lift pumps, seawater tanks, etc.), and BS1P, BS1S, BS3P, and BS3S are symmetrically arranged ballast tanks (and empty tanks). Each section is constructed in an inverted manner, and the equipment of each section is hoisted before the layered closure; as Figure 3 shown, the second layer is the M0 area (middle empty tank layer), divided into 7 sections: BT2C / BT2P / BT2S / BT1P / BT1S / BT3P / BT3S. BT2C is an empty tank at the central position, and BT1P, BT3P, BT1S, and BT3S are four groups of ballast tanks and / or empty tanks at the four corner positions respectively. BT2P and BT2S are empty tanks on both sides of BT2C, which can be equipped with water pumps and used as daily fresh water or domestic sewage tanks. The middle empty tank layer also has emergency towing points on the side; Each section is constructed in a side-erection manner, and the equipment of each section is hoisted before the layered closure; as Figure 4As shown in the figure, the third layer is the B0 area (top floating box layer). The top floating box layer is arranged in a surrounding manner (in a shape like the Chinese character 'Ri'), divided into 7 segments: BD1C / BD2C / BD3C / BD1P / BD1S / BD3P / BD3S. BD2C is located in the middle, with auxiliary rooms and switch rooms etc. set inside, and the rest are empty cabins. Feed rooms or feeding equipment rooms can also be set in some of the empty cabins for putting fish feed. Each segment is constructed in the normal building method, and the equipment of each segment is hoisted before the layered closure. As Figure 5 shown in the figure, the fourth layer is the D0 area (superstructure area layer / upper living and working area), divided into 2 segments: TD1C / TD2C (the living area and equipment area arranged vertically), used for configuring battery rooms, centralized control rooms, rest rooms and some outfitting parts etc. The segments are constructed in the reverse building method, and the equipment of each segment is hoisted before the layered closure.

[0018] As Figure 1 shown in the figure, the middle empty cabin layer also includes isolation components. The segmented structures of the middle empty cabin layer are arranged at intervals, and the isolation components are connected between the adjacent segmented structures of the middle empty cabin layer, separating the breeding space inside the middle empty cabin layer; The isolation components include a steel frame structure composed of several columns and crossbeams, and a net installed in the steel frame structure. The left and right sides of the steel frame structure are connected to the adjacent segmented structures of the middle empty cabin layer, and the upper and lower sides are respectively connected to the bottom floating box layer and the top floating box layer.

[0019] The segmented structures in the bottom floating box layer and the top floating box layer include positioning segments and surplus segments. The positioning segments are cut and built without surplus, and a surplus (30mm) is pre-set at the butt joint of the surplus segment and the corresponding positioning segment, and the surplus is cut off during the closure connection; The positioning segments in the bottom floating box layer and the top floating box layer include the left positioning segment, the middle positioning segment and the right positioning segment arranged along the ship width (such as the BS1C, BS2C, BS3C segments of the bottom floating box layer), and the corresponding surplus segments are arranged along the ship length direction; The upper and lower ends of each segmented structure of the middle empty cabin layer are respectively connected to the surplus segments of the bottom floating box layer and the top floating box layer. A surplus (30mm) is pre-set at the butt joint of the surplus segments of the bottom floating box layer and the top floating box layer and the corresponding middle empty cabin layer, and the surplus is cut off during the closure connection; In addition, for the column part of the isolation components connecting the bottom floating box layer and the top floating box layer, a 30mm closure surplus can also be added at the lower end. After the segment is formed and the segment completion accuracy measurement is carried out, it is cut first and then the large closure is carried out; a 30mm surplus is added at the lower end of the TD1C and TD2C segments of the superstructure area layer, which can be reserved during the segment construction and closure stages for leveling during the large closure (also pay attention to the floor height during the interior fitting-out). This embodiment also discloses a method for constructing a marine ranch fish box culture platform, such as Figure 6 As shown, the following steps are included: S10, prefabricate the various segmented structures in the bottom pontoon layer, fold and connect them to form the bottom pontoon layer, hoist the bottom pontoon layer, position it and adjust its level (after aligning it with the ground sample line, adjust the level, and after confirming that the positioning is correct, it can be positioned and fixed with the tire frame); S20, pre-fabricate each segment structure in the middle void layer, then hoist the corresponding segment structure, and position and weld it with the bottom pontoon layer (hoisting sequence ①BT2C, ②BT2S / BT2P, ③BT1S / BT3S, ④BT1P / BT2P); Then, the columns, beams and outfitting parts are hoisted and welded to the bottom pontoon layer and the middle empty tank layer; S30, prefabricate each segment structure in the top pontoon layer, fold and connect them to form the top pontoon layer, hoist the top pontoon layer and position weld it to the middle empty cabin layer, and finally weld it to the columns, etc.; S40, hoist the upper construction layer and weld it to the top pontoon layer; finally, complete the platform outfitting parts and peripheral life-saving equipment, etc.; S50, since the thickness of the constructed fish box body is relatively thin, it is connected to the embedded lifting lugs by partial replacement and excavation. There are 16 lifting lugs (80 tons), and then the fish box body is hoisted into the water as a whole. The estimated weight of the fish box body is 1260 tons. In this implementation, a 3600-ton gantry crane is used to hoist it into the water as a whole.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be deemed to fall within the protection scope of the technical solution of the present invention.
