Problems solved by technology

[0006] For this reason, the technical problem to be solved by the present invention is that the anti-scouring construction method of the existing offshore wind power single pile foundation leads to a large amount of rock riprap, serious damage to the single pipe pile by gravel, and poor controllability of the support stability of the wind turbine In order to provide an anti-scouring construction method for offshore wind power monopile foundations that is suitable for various harsh geological conditions and has a small amount of riprap and high support structure stability

Abstract

The invention discloses an anti-scouring construction method for a single-pile foundation of offshore wind power and belongs to the field of the construction process of offshore wind power plants. The method comprises the steps: determining an anti-scouring scope according to the installation positions of single pipe piles; paving an anti-scouring material layer in the anti-scouring scope; and installing single pipe piles on the anti-scouring material layer. The construction method solves the technical problems that the riprap project quantity is larger, the single pipe piles are seriously damaged by broken stone and the supporting stability and controllability of wind turbine generators are worse in the present construction method. And the construction method is particularly applicable to the construction of the wind power plants under the geological conditions based on sludge and powdered sandy soil.

Description

technical field [0001] The invention relates to an anti-scouring construction method for an offshore wind power single pile foundation, and belongs to the technical field of offshore wind power construction. Background technique [0002] With the rapid development of my country's economy, the demand for electricity in the whole society is increasing. The traditional power generation mode is to use coal to generate electricity, and the environmental pollution caused by coal power generation has become an important part of the haze control project in North China, East China and even the whole of China. Therefore, choosing clean electric energy has become an important issue to be solved. [0003] As a clean, renewable, and large energy storage energy, wind energy has attracted the attention of researchers in the field of power generation, thus opening the chapter of wind power generation. In wind power generation, offshore wind power is currently the most concerned. Judging f...
