Abstract

The invention relates to a construction method of an auxiliary platform. The auxiliary platform is installed beside a fan bearing platform, the construction method comprises the steps that firstly, jackets are fabricated and assembled into a whole, and then the jackets are hoisted; secondly, four auxiliary piles are vertically inserted at four corner points of each jacket, and the four auxiliary piles are fixed in the corresponding jacket; and finally, the remained auxiliary piles are hoisted and piled, and the remained auxiliary piles are fixed on sleeves of the corresponding jacket. The construction method of the auxiliary platform is simple in construction procedure, and influence of wind and waves on construction of the fan bearing platform is effectively reduced, and the working efficiency of construction of the bearing platform is improved.

Description

[0001] This application is a divisional application filed against the prior invention application, wherein the invention name of the prior application is: construction method for separate installation of offshore wind turbines, the application date is: 2017.7.26, and the application number is: 2017106188520. technical field [0002] The invention relates to the technical field of wind power generation, in particular to a construction method of an auxiliary platform. Background technique [0003] my country has a vast sea area and abundant offshore wind energy resources. The potential of sea wind wind power generation is huge. In recent years, with the development and application of new wind power technologies, new materials and new processes, offshore wind power with the characteristics of high power density and stable capacity is entering the large Scale building climax. [0004] As a new type of energy, offshore wind power is currently selected as an offshore environment th...
