Problems solved by technology

[0004] A large number of pile leg designs are used in the structural setting of the offshore windmill installation ship. Large pile legs are an important guarantee for the stability of the offshore windmill installation ship. However, due to their large volume during the manufacturing process of the pile legs, they can only be constructed in sections The method first divides the pile leg into sections, and then assembles each section. In the assembly process, due to the imperfect transfer process, the structural strength of the pile leg is far less than the theoretical value, and affects the production efficiency.

Abstract

The invention discloses a pile leg segmented construction method. A pile leg body is of an octagon plate frame structure, and a pile leg is divided into seven subsections from bottom to top. The method comprises the steps of steel plate blanking, jig frame manufacturing, support plate using, subsection assembling, whole section forming by folding middle group three-dimensional subsections in advance and assembling according to given assembly sequence. Assembly is conducted by combining traditional large equipment, strict management and control can be achieved in the data mode in the pile leg construction process, setting is conducted on related technological steps through reasonable technological parameters, and according to actual production verification, the pile leg segmented construction method can effectively improve the production efficiency.

Description
