Jacket manufactured in factory and spliced by bolts on site and construction method

Abstract

The invention relates to a jacket manufactured in factory and spliced by bolts and a construction method. The jacket manufactured in factory and spliced by bolts comprises jacket columns (1), jacket diagonal rods (2) and jacket cross rods (3), the jacket columns (1) are of segmented spliced structures, adjacent segments are spliced and fixed through bolt splicing pieces to form tower column splicing points (6), a connector used for connecting the jacket inclined rod (2) and the jacket cross rod (3) is pre-arranged on the outer side of the jacket column (1), the jacket inclined rod (2) is obliquely arranged, and the jacket cross rod (3) is horizontally arranged. The two ends of the jacket inclined rods (2) and the two ends of the jacket cross rods (3) are respectively spliced and fixed with corresponding connectors on the jacket columns (1) through the bolt splicing pieces to form web member splicing points (4). Compared with the prior art, the jacket has the advantages of being rapid and efficient to build, long in service life and the like.

Description

technical field [0001] The invention relates to the technical field of connection of offshore wind power structures or other offshore steel structures in structural engineering, and in particular relates to a jacket and a construction method manufactured in a factory and spliced ​​with bolts on site. Background technique [0002] At present, the country is developing large-scale offshore wind farms, and the development of offshore wind power steel structures is large and wide-ranging. The power of a single wind turbine has increased, and the structural volume has also increased. The development of offshore wind turbines to remote sea areas and the increase of water depth have brought new challenges to the construction of traditional offshore jackets. [0003] The construction of the traditional offshore jacket is carried out at the seaside assembly site. The high-altitude operation process is cumbersome, the construction period is long, the cost is high, the weld quality can...
