Inflation transportation water-pressing-pile fixing type foundation of offshore wind power tower

Abstract

The invention discloses an inflation transportation water-pressing-pile fixing type foundation of an offshore wind power tower. The foundation comprises a cavity and multi-stage water pressing piles arranged in the cavity. Multiple air inlet valves and multiple water inlet valves are arranged on the surface of the cavity. Each multi-stage water pressing pile comprises a U-shaped cylinder and multi-stage hollow piston rods nested sequentially. Air is injected into the cavity after the cavity and the wind power tower are assembled, and the cavity and the wind power tower are dragged to a wind power plant construction site; the interior of the cavity is filled with water till the cavity sinks to the seabed; then high-pressure sea water is pressed into the U-shaped cylinders to push all stages of the hollow piston rods to be drilled into gravel holes stage by stage till limit positions; and water is pumped out, concrete is poured into the multi-stage water pressing piles, and the permanent foundation of the wind power tower is formed after the concrete is solidified. According to the foundation, the foundation is reasonable in structure and convenient to manufacture, transport and mount; the work amount of manufacturing and the work amount of mounting are reduced, the construction period is shortened, and it is guaranteed that a wind power plant is combined to the grid and generates power as soon as possible; the foundation of the offshore wind power tower has great economic benefits.

Description

technical field [0001] The invention belongs to the technical field of wind power equipment, and relates to an offshore wind power tower foundation fixed by an inflatable transportation hydraulic pile. Background technique [0002] As the world's energy becomes increasingly tense, wind power generation, as a source of new energy, is valued by countries all over the world. my country's vast sea area contains abundant wind energy resources, especially the development of wind power in offshore areas has huge economic value. [0003] Offshore wind power is different from inland wind power in that the construction of its tower foundation is difficult and is easily affected by the weather environment. At the same time, the existing offshore wind power has problems such as long manufacturing and installation cycle and difficult fixing. At present, the commonly used method is to manufacture wind power towers and their foundations inland, assemble the wind power towers and foundati...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the problems of high offshore construction and installation costs of the traditional wind power tower foundation and the large amount of installation work, the present invention proposes an offshore wind power tower foundation fixed by inflatable transport hydraulic piles, which makes the offshore wind power tower foundation convenient to manufacture , and convenient for transportation and installation, thereby reducing the construction period and cost
