Description

Technical Field

[0001] The present invention relates to a comprehensive platform, in particular to a construction process for a large floating deep - sea and far - sea aquaculture and power generation comprehensive platform. Background Art

[0002] The construction of a deep - sea and far - sea aquaculture and power generation comprehensive platform is an interdisciplinary project integrating ocean engineering, new energy technology, and intelligent aquaculture, aiming to achieve the coordinated development of "offshore granary + green energy". The deep - sea and far - sea aquaculture and power generation comprehensive platform needs to break through three core problems: structural design, energy coordination, and ecological compatibility. Through cross - field technology integration (such as floating wind power + intelligent aquaculture), it can achieve a win - win situation in economic and ecological benefits.

[0003] Chinese Patent with application number CN202410710639.2, an integrated platform for deep - sea aquaculture and thin - film photovoltaic power generation, combines an oscillating float - type wave energy power generation device and a pendulum - type wave energy power generation device and arranges them at the front end of the photovoltaic power generation platform. It is connected to an external turret mooring system and a deep - sea aquaculture cage through a rigid connecting rod. This layout design method effectively reduces the wave impact force directly acting on the photovoltaic platform while reducing the gap between power generation devices without affecting the power generation efficiency of the wave energy device. However, this comprehensive platform has the following defects:

[0004] 1. The weight of the deep - sea and far - sea aquaculture and power generation comprehensive platform is lighter than that of general offshore floating steel structures, but it occupies a larger assembly site. The traditional construction and assembly method has a large number of docking joints at the assembly joint, takes a long time to occupy the site, and has a low site turnover rate, making it difficult to construct in batches and rhythmically, and the economy is poor;

[0005] 2. It is difficult to position the assembly at the nodes where multi - dimensional pipe structures intersect, and it is difficult to guarantee the construction quality, which in turn affects the construction period and economy;

[0006] 3. Due to the circumferential shape of the construction surface of the cylindrical pipe structure segments, there is a situation of overhead welding in the conventional construction method, and the construction difficulty is large;

[0007] 4. When the platform is assembled, there are many cylindrical docking nodes, the assembly positioning difficulty is large, and the construction period is long;

[0008] 5. When the vertical pipe structure segments are assembled, they are prone to overturning, and the safety is poor;

[0009] 6. It is difficult to guarantee the construction accuracy of the platform mainly composed of pipe structures. Summary of the Invention

[0010] The main purpose of the present invention is to provide a construction process for a large floating deep - sea and far - sea aquaculture and power generation comprehensive platform to solve the problems raised in the related technology.

The lower layer node part includes a lower layer central pipe node 11 and several lower layer peripheral pipe nodes 12, 13. The lower layer column pipe part includes several lower layer radial pipes 14 and several lower layer horizontal pipes 15. The lower layer peripheral pipe nodes 12 and 13 are alternately fixedly connected through the lower layer horizontal pipes 15. One end of each lower layer radial pipe 14 is fixedly connected to the outer ring of the lower layer central pipe node 11, and the other end is fixedly connected to the lower layer peripheral pipe nodes 12, 13.

[0086] The lower layer peripheral pipe node 12 is not connected to the vertical bracing pipe 18, the lower layer peripheral pipe node 13 is connected to the vertical bracing pipe 18, the upper layer peripheral pipe node 22 is connected to the vertical bracing pipe 18, the upper layer peripheral pipe node 23 is not connected to the vertical bracing pipe 18.

The two ends of the vertical bracing pipe 18 are respectively fixedly connected to the lower layer peripheral pipe nodes 12, 13 and the upper layer peripheral pipe nodes 22, 23.

[0089] As Figure 1 shown in the figure, the fan foundation pipe 3 is fixedly arranged at the top end of the upper layer central pipe node 21, and the fan 4 is fixedly arranged at the top end of the fan foundation pipe 3.

[0090] In S2, as Figure 3 shown in the figure, on the roller-type special tire rack 51, the riser pipes, horizontal pipes and other cylindrical segments 52 are constructed. After the components below are installed, the construction surface of the cylindrical segment 52 is replaced by rotating the electric roller 53.

[0091] In S3, the prefabrication site line includes a lower layer ground wire group and an upper layer ground wire group. As Figure 4As shown in the figure, the lower ground wire group includes the center ground wire 61 of the lower layer platform of the prefabrication yard, several lower layer radiation ground wires 62 of the prefabrication yard, several lower layer peripheral contour ground wires 63 of the prefabrication yard, and several center ground wires 64 of the lower layer peripheral columns of the prefabrication yard, as Figure 6 shown, the upper ground wire group includes the center ground wire 81 of the upper layer platform of the prefabrication yard and several upper layer radiation ground wires 82 of the prefabrication yard.

[0092] In S4, as Figure 7 shown, according to the closed ground wire, first position the lower layer center pipe node 11, then sequentially position each lower layer peripheral pipe node 12 and each lower layer peripheral pipe node 13, and then install each lower layer horizontal pipe 15 and each lower layer radiation pipe 14 to form the lower layer segmented part 1.

[0094] In S6, as Figure 9 shown, according to the upper ground wire group surveyed and marked during the prefabrication of the upper layer segments, first position the upper layer center pipe node 21, and then sequentially install each upper layer radiation pipe 24 to form the upper layer segmented part 2.

[0095] In S7, as Figure 10 shown, mark the closed ground wire on the closed ground. The closed ground wire includes the center column ground wire 91 of the closed ground platform, several closed ground radiation ground wires 92, several closed ground outer column ground wires 93, and several closed ground pier position lines 94.

[0096] In S8, as Figure 11 shown, set several closed piers 10 on the closed ground according to the layout of the lower layer structure of the platform.

[0097] In S9, as Figure 12 shown, position the lower layer segmented part 1 of the closed platform. After positioning, weld and seal the lower layer segmented part 1 with the ground embedded iron using channel steel or the like.

[0098] In S10, as Figure 13As shown in the figure, before positioning and closing, weld 3 root fixing plates 111 on the central column 16 at a height approximately 2 / 3 from the ground, and at the same time connect 3 steel wire ropes 112 to the root fixing plates 111. After the central column 16 is positioned and closed, fix the other ends of the steel wire ropes 112 to the ground to prevent the central column 16 from falling down. Before positioning and closing, install 3 positioning plates 113 at the end of the central column 16 at the lower-layer segmented part 1 to assist in positioning and guiding the central column 16 and achieve quick closing in place. After the positioning of the central column 16 is completed, weld and seal the central column 16 to the lower-layer segmented part 1 using the positioning plates 113.

[0099] When prefabricating the "door"-shaped segment 121, it is necessary to mark the axis group of the "door"-shaped segment, as Figure 5 shown. The axis group of the "door"-shaped segment includes the center line 71 of the upper-layer horizontal pipe, the center lines 72 of the two vertical pipes, and the center line 73 of the vertical support pipe.

[0100] According to the axis group of the "door"-shaped segment, first position and install the upper-layer outer pipe nodes 23 and the upper-layer outer pipe nodes 22, and then sequentially position and install the outer vertical pipes 17, the upper-layer horizontal pipe 25, and the vertical support pipe 18 to form the "door"-shaped segment 121.

[0102] In S11, as Figure 14 shown, before positioning and closing, weld 3 root fixing plates 131 at approximately 2 / 3 height from the ground on each of the two outer vertical pipes 17 of the "door"-shaped segment 121, and at the same time connect 3 steel wire ropes 132 to the root fixing plates 131. After the "door"-shaped segment 121 is positioned and closed, fix the other ends of the steel wire ropes 132 to the ground to prevent the "door"-shaped segment 121 from falling down. Before positioning and closing, install 3 positioning plates 133 at the end of the outer vertical pipes 17 of the lower-layer segmented part 1 to assist in positioning and guiding the "door"-shaped segment 121 and achieve quick closing in place. After the positioning of the "door"-shaped segment 121 is completed, weld and seal the "door"-shaped segment 121 using the positioning plates 133.

[0103] In S12, as Figure 15 shown, use a method similar to the eleventh step to install positioning plates 133 at the ends of the upper-layer horizontal pipe 25 and the vertical support pipe 18 of the already closed lower-layer segmented part 1 and the "door"-shaped segment 121 to assist in quickly positioning and closing the remaining upper-layer horizontal pipe 25 and the vertical support pipe 18. After positioning is completed, weld and seal the upper-layer horizontal pipe 25 and the vertical support pipe 18 using the positioning plates 133.

[0104] In S3, as Figure 16As shown in the figure, use a method similar to the eleventh step to install the positioning horse plate 133 at the end of the upper radiation tube 24 of the "gate"-shaped segment 121 that has been closed, assist the upper segment part 2, and after positioning, use the positioning horse plate 133 to weld and seal the upper segment part 2.
