Construction method of aquaculture cage based on the multi-pile cap foundation of offshore wind power that has been built

Abstract

The invention belongs to the field of offshore wind power engineering, and specifically relates to a construction method for aquaculture net cages based on the multi-pile cap foundation of offshore wind power that has been built, comprising the following steps: installing the first hoop on the pile leg; Install the fixing piece on the first hoop; install the other hoops on the pile legs along the fixing piece; install the anchor chain ring of the net with the hoop, tie the edge of the net to the fixing piece, and complete the installation of the net . The beneficial effects of the present invention are as follows: the construction method of installing the net clothing through the hoop and the fixing parts is low in difficulty, no underwater welding operation is required, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of offshore wind power engineering, and in particular relates to a construction method for aquaculture net cages based on the built multi-pile cap foundation of offshore wind power. Background technique [0002] As a renewable energy source, offshore wind power has developed rapidly in recent years. Among them, high pile caps are used in many places in our country. The foundation structure of the high pile cap includes a concrete cap above sea level and a group of steel pipe piles at the bottom of the cap. It is connected with the wind power tower through the flange, so that the wind turbine and the foundation are integrated. [0003] For my country's marine fishery cage culture, it began in the late 1970s and developed rapidly in the 1990s, and the number of cultured species is also increasing day by day. However, due to the harsh marine environment and frequent extreme weather, this is a great challenge to the ma...

Problems solved by technology

However, due to the harsh marine environment and frequent extreme weather, this is a great challenge to the material, structure, wind and wave resistance of the cages and the mooring system of the cages. Inner Gulf or inshore farming

[0004] Nowadays, offshore wind power is also concentrated in offshore areas, which conflicts with the sea used for marine aquaculture. Based on this, some people propose to combine high pile cap foundations for offshore wind power with offshore fishery cage culture. However, the existing technology is not suitable for aquaculture cages How to proceed with the construction has never given a convincing solution
