Manufacturing technology for pile shoe of ocean platform

Abstract

The invention discloses a manufacturing technology for a pile shoe of an ocean platform. The manufacturing technology comprises the steps that lower base plates and an intermediate stand column are spliced and welded, and then inner rib plates, lower base plate inner T row plates and lower base plate outer T row plates are sequentially assembled; secondly, outer upper base plate assemblies are reversely buckled, and the lower base plate outer T row plates are sequentially welded to the outer upper base plate assemblies and the lower base plates; then intermediate partition plates are arranged in an inserted mode; the inner rib plates, the lower base plate T row plates, the intermediate partition plates and the lower base plates are sequentially welded, and then vertical angle welding is carried out on the inner rib plates and the intermediate stand column; then diffusion welding is carried out on upper base plate inner sectional materials; finally three inner upper base plates are sealed; and when three intermediate splicing plates are welded, one side edges of the three intermediate splicing plates are firstly welded to the corresponding edges of three side cover plates, then heating and heat preservation are carried out, the other side edges of two intermediate splicing plates are welded to the corresponding edges of two side cover plates, then heating and heat preservation are carried out, finally, the other side edge of the rest one intermediate splicing plate is welded to the corresponding edge of the rest one side cover plate, and then heating and heat preservation are carried out. According to the manufacturing technology, the staged manufacturing efficiency can be improved.

Description

technical field [0001] The invention relates to a manufacturing process of a spud can of an ocean platform. Background technique [0002] Offshore platforms are structures that provide production and living facilities for activities such as drilling, oil production, transportation, observation, navigation, and construction at sea. The lower part of the offshore platform is directly supported by piles, expanded footings or other structures and fixed to the seabed. The spud cans of the offshore platform are triangular and include a central column with a hexagonal upper tire at the lower end, three lower bottom plates fixed on the edge of the upper tire of the central column, six vertical spuds fixed on the lower bottom plate with the inner ends facing the central column Internal ribs, multiple internal T-rows of the lower base plate fixed inside the lower base plate, three intermediate partitions vertically fixed on the lower base plate and surrounded by six internal ribs to ...

AI Technical Summary

Problems solved by technology

[0005] 2) The six internal ribs 31 and 32 are designed asymmetrically at an interval of 60°, which makes it more difficult to control the verticality of the middle column 1 during the welding process;

[0008] 5) Excessive structural deformation of the lower base plate 2 will cause difficulties in the assembly and construction of the outer upper base plate assembly 7, and after the outer upper base plate assembly 7 is fastened, the working environment inside the middle partition plate 5 will form a closed and narrow space , which increases the risk of the operation
