Embodiment 1

[0032] refer to Figure 1-3 , the present invention provides an anti-corrosion shell structure of an ocean engineering platform, comprising: four support columns 1 inserted into the seabed, a connection block 2 is fixedly connected to the top surface of the support column 1, and several connection columns are fixedly connected to the top surface of the connection block 2 3. The top surface of the connection block 2 is provided with a load-bearing plate 4, and the bottom surface of the load-bearing plate 4 is provided with a number of connecting grooves that match the connecting columns 3. The connecting columns 3 are plugged into the connecting grooves, and the top surface of the load-bearing plate 4 is provided with a protective plate 5 , the top surface of the protective plate 5 is fixedly connected with a protective cover 6, the protective cover 6 is provided with a filter device, the bottom surface of the filter device is fixedly connected with a water-proof layer 7, the bo...

Embodiment 2

[0055] refer to Figure 4 , because the support column 1 of the offshore platform has no protective device, it is easily corroded by seawater, and its service life is very short. Therefore, in this embodiment, a heating film 26 is arranged on the outer wall of the support column 1. The heating film 26 provided is the prior art, so it is not enough For more details, the heating film 26 is fixed to the inner concrete layer 27, and the inner concrete layer 27 is embedded with a conductive coil 28. The conductive coil 28 is electrically connected to the heating film 26, and the conductive coil 28 is externally connected to a power supply. The outer wall is fixed with an insulating layer 30, and an anti-corrosion shell 31 is arranged outside the insulating layer 30, and the heating film 26 is powered through the conductive coil 28, and finally the heating film 26 is heated to generate heat, which generates heat around the support column 1, preventing the support column 1 from contac...

Embodiment 3

[0057] refer to Figure 5 , in order to reduce the self-weight of the support column 1 as a whole, enhance plasticity, improve the seismic performance of the structure, and facilitate construction, the support column 1 in this embodiment is made of steel column material, and the outer concrete layer 32 is poured on the outside of the support column 1. At the same time, steel bars 29 are spirally embedded in the outer concrete layer 32 to increase the bearing capacity, durability and safety of the support column 1 .

Abstract

The invention discloses an anti-corrosion shell structure and a construction method of an ocean engineering platform, comprising: four support columns inserted into the seabed, a connection block is fixedly connected to the top surface of the support column, and a plurality of connection columns are fixedly connected to the top surface of the connection block. The top surface of the block is provided with a load-bearing plate, and the bottom surface of the load-bearing plate is provided with a number of connecting grooves that are compatible with the connecting columns. The connecting columns are plugged into the connecting grooves. , the protective cover is provided with a filter device, the bottom surface of the filter device is fixed with a water-proof layer, the bottom surface of the water-proof layer is fixed with the top surface of the protective plate, and the two opposite sides of the protective plate are respectively provided with a number of water holes, which are respectively located in the A number of water holes on both sides of the protective plate are respectively connected one by one. A number of communication holes are opened on the top surface of the protective plate, and the bottom of some communication holes are connected with the water holes. The top of the hole is connected, and the four peripheral surfaces of the load-bearing plate are respectively equipped with salt scraping devices.

Description

technical field [0001] The invention relates to the technical field of ocean engineering, in particular to an anti-corrosion shell structure and construction method of an ocean engineering platform. Background technique [0002] Ocean engineering refers to new construction, reconstruction, and expansion projects for the purpose of developing, utilizing, protecting, and restoring marine resources, and the main body of the project is located on the seaward side of the coastline.
