Temporary construction platform of rock-socketed single pile foundation of offshore wind turbine

Abstract

The invention discloses a temporary construction platform of a rock-socketed single pile foundation of an offshore wind turbine. The temporary construction platform of the rock-socketed single pile foundation of the offshore wind turbine is a jacket structure formed by connecting four auxiliary tubular piles (2) and stay bars (6), and is characterized in that pile distances among the four auxiliary tubular piles (2) are 18 m, and the height of a jacket platform is 20 m; a second platform (5) and a first platform (4) are respectively arranged at positions which are distant from the top end of the jacket structure by 5 m and 2 m, and jacks are respectively mounted on the second platform (5) and the first platform (4) and are used for adjusting perpendicularity of a steel casing (1); a mudmat (3) is arranged at the bottom of the jacket structure; and a limiting component is arranged on the first platform (4), and brackets are shelved on the limiting component and stop the steel casing against sinking. By the temporary construction platform of the rock-socketed single pile foundation of the offshore wind turbine, the problem that the rock-socketed single pile foundation of the offshore wind turbine is difficult to construct on a rock supported sea floor with a shallow surface residual overburden is solved effectively, a powerful support is provided for introduction of an offshore wind turbine rock-socketed single pile foundation technology to the offshore wind powder industry, and project cost is reduced.

Description

technical field [0001] The invention relates to the technical field of wind turbine foundation construction in the offshore wind power industry, in particular to a temporary construction platform for offshore wind turbine rock-socketed single pile foundations. Background technique [0002] The biggest difference between offshore wind power generation and onshore wind power generation lies in the different locations of the two. Since the foundation of the offshore wind turbine is at sea, many additional loads and uncertain factors are added, so the design is more complicated, and the structural form is also different due to the The sea conditions are diverse. There are two most commonly used fixed foundations for rock-based seabed offshore wind turbines, rock-socketed monopile and gravity type. Gravity foundations require the use of large "centipede vehicles" for prefabricated on-site transportation, as well as large floating cranes and other equipment, but such equipment is...

AI Technical Summary

Problems solved by technology

Gravity foundations require the use of large "centipede trucks" for prefabricated in-site transportation, as well as large floating cranes and other equipment, but such equipment is lacking in China. At present, there is no precedent for the construction of rock-socketed single piles for offshore wind turbine foundations in China.
