Abstract

The invention belongs to the technical field of offshore wind power, and particularly relates to a sheet body prefabricating process for an offshore wind power jacket, which comprises two procedures of prefabrication of an upper sheet body and prefabrication of a lower sheet body, the prefabrication of the upper sheet body and the prefabrication of the lower sheet body both comprise nine procedures of pattern sheet prefabrication, ground marking, field pier arrangement, profiling tool manufacturing and installation, line returning, hoisting, cross pattern sheet opening trimming, assembling and welding. According to the method, the prefabrication of the sheet body is realized through nine procedures of prefabrication of the pattern sheet, ground scribing, field pier arrangement, profiling tool manufacturing and mounting, line returning, hoisting, opening trimming of the cross pattern sheet, assembling and welding, the whole process is high in accuracy, the construction is simple, the strength of a welded finished product is high, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power, and in particular relates to a sheet body prefabrication process for an offshore wind power jacket. Background technique [0002] At present, the application of cast steel joints in China has just emerged. In the National Stadium (Bird's Nest), the new terminal building of Chongqing Jiangbei International Airport, Harbin Convention and Exhibition Center and other large-span structures, cast steel joints are used for complex joints and have achieved good results. Economic benefits, the domestic jacket horizontal piece prefabrication adopts the traditional direct welding process of tension pipe and node pipe, and cast steel nodes are used for the construction of the jacket. Fields have strong advantages. [0003] In the prefabrication of the sheet, it is difficult to assemble and operate during construction, which may easily lead to low precision and low efficiency of the finished prod...
