Three-leg jacket building technology

Abstract

The invention relates to a three-leg jacket building technology which comprises the following steps: at first, dividing a support seat into three segments distributed from top to bottom, then, manufacturing pipe bodies required by assembling of all components, taking the pipe bodies with different sizes and required by assembling to assemble an X-shaped connecting seat and a connecting sleeve, assembling the X-shaped connecting seat and the pipe bodies to form an X-shaped connecting piece, mounting the connecting sleeve on steel pipe pile segments formed by straight pipe bodies in a sleeving manner, assembling the steel pipe pile segments with the X-shaped connecting piece to form segment support seats, then, manufacturing an upper platform, folding the upper platform and the vertical typeplane of the segment support seat at the uppermost end to form an assembly part A, then, folding the horizontal planes of the rest two segment support seats to form an assembly part B, and finally, folding the assembly part A and the assembly part B to form the three-leg jacket. The three-leg jacket building technology has the following advantages: the support seat is divided to three segments, so that the processing size precision of each segment is conveniently controlled to enable the overall precision to be higher.

Description

technical field [0001] The invention relates to the field of offshore wind power generation, in particular to a construction process for a three-leg jacket. Background technique [0002] In my country, offshore wind power generation is a new type of industry. After 2007, my country began to gradually develop the offshore wind power generation industry. As the installed capacity of offshore wind turbines increases year by year, the basis of offshore wind power is diversified. When other renewable energy sources (such as biomass energy, tidal energy, etc.) are not yet mature, wind energy has become one of the primary choices for alleviating global environmental problems and energy crises. one. At present, among various foundation types of offshore wind turbines, single pile, jacket, underwater three-pile and above-water three-pile foundation types are the most commonly used types. [0003] Among them, the jacket foundation, as a relatively mature foundation type, has been wi...

Problems solved by technology

Due to the closed triangle between the main cylinder of the jacket and the support tube, and the large volume of the jacket, it is difficult to assemble after segmental fabrication, and the length of each segment is difficult to control accurately, resulting in low manufacturing accuracy

At the same time, its disadvantage is that there are many relative nodes, and each node requires special processing, which requires a lot of manpower, material and financial resources, which increases the investment cost of offshore wind power to a certain extent.
