Combined type composite offshore wind power pile and installation method thereof

Abstract

The invention provides a combined type composite offshore wind power pile. The wind power pile comprises a pile body, the pile body comprises a plurality of circular arc plates, a first cavity is arranged on the inside of each circular arc plate, both ends of the circular arc plates are provided with a connecting member, and two circular arc plates are fixed by the connecting members to form a whole. When two circular arc plates are fixed to form a whole, a second cavity is formed between two adjacent connecting members. The pile body has the characteristics of high corrosion resistance, longservice life and low weight, can lower the requirements for floating crane, and, compared with a steel pile, is longer in service life, lower in production cost and higher in economic benefits. The combined type composite offshore wind power pile has a simple and convenient installation method, and is convenient to operate and easy to popularize.

Description

technical field [0001] The invention relates to the field of infrastructure construction of offshore wind power plants, in particular to a combined composite material offshore wind power pile and an installation method thereof. Background technique [0002] Composite piles for offshore wind power are mainly used in offshore wind power and other fields. The existing offshore wind power piles are mainly steel pipe piles. Steel pipe piles are eroded by marine microorganisms, wind waves, seawater salt, etc., and are prone to rust, which greatly reduces the service life of the piles. The design life is only 20 years. Most of them are made of composite materials, with a service life of more than 70 years. The short service life of steel piles greatly increases the maintenance and replacement costs of fans. Furthermore, steel pipe piles are heavy, requiring high requirements for the installation of lifting ships, and the construction period is long. The offshore wind power steel p...

Problems solved by technology

The existing offshore wind power piles are mainly steel pipe piles. Steel pipe piles are eroded by marine microorganisms, wind waves, seawater salt, etc., and are prone to rust, which greatly reduces the service life of the piles. The design life is only 20 years. Most of them are made of composite materials, with a service life of more than 70 years. The short service life of steel piles greatly increases the maintenance and replacement costs of fans

Furthermore, steel pipe piles are heavy, requiring high requirements for the installation of lifting ships, and the construction period is long. The offshore wind power steel pile structure itself has shortcomings such as short life, easy corrosion, heavy weight, and environmental pollution, and the installation and construction costs are high.
