Problems solved by technology

However, there are strong winds and waves at sea, and it is difficult to fill the concrete slurry underwater, and a large amount of concrete slurry is wasted, which increases the construction cost.
Therefore, it will seriously affect the installation of the foundation support structure of offshore wind turbines.

Abstract

The invention discloses a jacket support structure capable of being connected through grouting. A plurality of hollow steel piles are driven into a sea floor and fixed, grouting guide pipes are welded on jacket support legs, the upper end of the grouting guide pipe is arranged on a jacket platform, tail ends of jacket support legs are inserted in ports at the upper ends of the steel piles to form connection gaps, tail ends of grouting guide pipes are inserted into the connection gaps, constructors can guide concrete slurry into the connection gaps of the jacket support legs and the steel piles on the jacket platform by using the grouting guide pipes, reliable connection of the jacket support legs with the steel piles can be guaranteed, and the jacket support structure has the advantages of being low in construction cost, low in construction difficulty and convenient to operate.

Description

【Technical field】 [0001] The invention relates to a jacket support structure of an offshore wind power generator, in particular to a jacket support structure that can be connected by grouting. 【Background technique】 [0002] With the application and promotion of offshore wind turbines, especially the rapid development of high-power wind turbines and deep-water offshore wind farms, jackets that are light in weight, easy to transport and install are usually used as the basic support structure of offshore wind turbines. When installing the steel pile, first drive the steel pile into the seabed and fix it, then insert the end of the jacket support leg into the upper port of the steel pile, and then fill the gap between the jacket support leg and the steel pile with concrete slurry to make the connection reliable. However, there are strong winds and waves at sea, and the construction operation of filling concrete slurry underwater is difficult, and a large amount of concrete slur...
