Pile leg shell section butt joint method

Abstract

The invention discloses a pile leg shell section butt joint method, and relates to the technical field of offshore wind power installation boats. The pile leg shell section butt joint method comprisesthe following steps that roller carriers are installed; star-shaped supports are arranged in pile leg shell sections; the two pile leg shell sections are connected and folded through connecting devices and inserting shell sections; the pile leg shell sections are leveled; butt joint welding is conducted; stress is eliminated; a pile leg falls back. The pile leg shell section butt joint method hasthe advantages that the star-shaped supports are arranged in the pile leg shell sections to prevent the butt joint pile leg shell sections from deforming, the two pile leg shell sections are connected and folded through the connecting devices and the inserting shell sections, the butt joint pile leg shell sections are firmer in structure, the pile leg shell sections are convenient to weld throughinstallation of the roller carriers, the overall straightness is good, and the welding quality is good; stress relief is conducted through beam supporting after welding, the structure is stable, thestress relief treatment effect is good, cracks and deformation are not prone to occurring, the pile leg shell section butt joint method can be used for butt joint of large shell sections, and straightness and opening precision are guaranteed.

Description

technical field [0001] The invention relates to the technical field of offshore wind power installation ships, in particular to a butt joint method of pile legs and barrel joints. Background technique [0002] The development and utilization of offshore wind energy has become a highlight in the world's new energy development. The wind power installation ship is a brand-new marine engineering ship, mainly used for the transportation and hoisting of offshore wind power equipment. It integrates the functions of a transport ship, an offshore operation platform, a crane ship and a living supply ship, and can be completed independently. The transportation and installation work mentioned above. Its working principle is: the hull extends the legs into the seabed through the lifting system. When the legs reach the seabed, it can lift the hull a certain distance from the water surface to bear the weight of the hull, providing a stable working platform for the installation of offshore...
