Abstract:
The present disclosure relates to a grouting and welding combined connection joint and an offshore installation method thereof, characterized in that: it comprises a set of grouting systems disposed inside of the annular space formed by an inner shell of the central pore canal of a column with large cross section and an outer wall of a column with small cross section, as well as a group of brackets welded on a top deck of a column with small cross section and an inner shell of the central pore canal of the column with large cross section. The grouting and welding combined connection joint provided by the present disclosure has advantages of being able to adapt to the connection of different dimensions of columns, and having simple offshore installation, highly reliable structural safety and low cost.
