Abstract

The invention discloses a temporary construction platform for a rock-socketed single-pile foundation for an offshore fan, which is a jacket structure formed by connecting four auxiliary pipe piles (2) and struts (6). The pile distance between the pipe piles (2) is 18m, and the height of the jacket platform is 20m; platform two (5) and platform one (4) are respectively set at 5m and 2m from the top of the jacket structure, and platform two ( 5) A jack is installed on both platform one (4) to adjust the verticality of the steel casing (1); an anti-sinking plate (3) is arranged at the bottom of the jacket structure; a limiter is set on platform one (4). Positioning member, the corbel rests on the limiting member, and the tissue steel casing sinks. It effectively solves the problem of shallow rock bed and seabed in the surface residual layer and the construction of rock-socketed single-pile foundation for offshore wind turbines, provides strong support for the introduction of rock-socketed single-pile foundation technology for offshore wind turbines in the offshore wind power industry, and reduces engineering costs.

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...
