Jacket offshore wind turbine foundation with brackets and construction method thereof

Abstract

The invention discloses a jacket offshore wind turbine foundation with brackets. The jacket offshore wind turbine foundation with the brackets comprises a jacket, foundation piles, bracket flanges and the construction brackets, wherein the foundation piles are arranged in guide pipes of the jacket and extend to be embedded into a foundation; the bracket flanges are arranged on the guide pipes; and the construction brackets are connected with the guide pipes through the bracket flanges. According to the jacket offshore wind turbine foundation with the brackets, a temporary supporting system is formed through auxiliary piles constructed in advance, the jacket is placed on the supporting system in a suspended mode through the construction brackets, then the guide pipes of the jacket serve as a positioning guiding device so that the foundation piles can be piled, and finally grouting connection is conducted on the foundation piles and the guide pipes. By the adoption of the jacket offshore wind turbine foundation with the brackets, structure fixing and stabilizing of the suspended jacket during the construction period are achieved; positioning, guiding, pile clamping and the like of offshore construction of the foundation piles are achieved; and in addition, the height of the jacket can be reduced, and steel materials are saved. The structure is easy and convenient to construct, good in feasibility and suitable for areas with large water depths and thick covering layers and has broad application prospects in offshore wind power projects. The invention further discloses a construction method of the jacket offshore wind turbine foundation with the brackets.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power engineering, and in particular relates to a jacket offshore wind turbine foundation with corbels and a construction method thereof. Background technique [0002] Due to the offshore construction, the working conditions are relatively harsh, and it is greatly affected by natural conditions. The operating time is short and the construction is difficult. [0003] The jacket is currently one of the most commonly used types of marine engineering infrastructure. Due to its advantages of high overall rigidity, small wave force, and small structural deformation, it is suitable for sea areas with various water depths. Therefore, it is widely used in the fields of offshore oil and offshore wind power. The application is more extensive. The conventional jacket construction method is to place the structure on the mud surface of the seabed, and the steel cylinder at the lower end is connected to t...

AI Technical Summary

Problems solved by technology

It solves the problem of fixing and stabilizing the structure of the suspended jacket during the construction period; secondly, it solves the problems of positioning, guiding, and clamping piles in offshore construction of foundation piles. The quality of grouting can be inspected by dry method, and the height of the jacket can be reduced, saving Steel, the structure is easy to construct, the construction period is short, and the implementability is good. It is suitable for areas with large water depths and thick covering layers.
