Three-barrel-foundation suction pile supporting box girder anemometer tower and construction method

Abstract

The invention discloses a three-barrel-foundation suction pile supporting box girder anemometer tower and a construction method. The three-barrel-foundation suction pile supporting box girder anemometer tower comprises suction piles, stand columns, a box girder platform, a tower frame and a lifting device, wherein the box girder platform is of a Y-shaped solid structure, the lifting device is connected with the box girder platform through steel strands, the stand columns penetrate through constraint holes of the box girder platform, bottom ends of the stand columns are welded to top ends of the suction piles, top ends of the stand columns are welded to bottom ends of the lifting devices, and the triangular supporting structures at the bottom of the tower are welded to three branches of the box girder platform correspondingly. The three-barrel-foundation suction pile supporting box girder anemometer tower is advantaged in that a suction pile of an anemometer tower enters mud through self weight, the box girder platform is lifted through the lifting device after the suction pile penetrates in place, use of a floating crane and a large barge is avoided, the anemometer tower structure can be applied to sea areas with different depths and different environments only by changing the length and the radius of the stand column and the suction pile, the application range is wide, construction cost is reduced for offshore safety operation, and meanwhile convenience is provided for providing wind characteristic data.

Description

technical field [0001] The invention relates to an anemometer tower and a construction method, in particular to an anemometer tower supported by a three-tube foundation suction pile supporting a box girder and a construction method, and belongs to the technical field of offshore wind power. Background technique [0002] The development of renewable energy is the key to coping with climate change, optimizing the energy structure, and solving energy and environmental problems. my country has huge reserves of wind energy resources, and wind power is a kind of clean energy. The development of wind power is one of the ways to sustainable energy development.

Problems solved by technology

[0003] At present, steel pipe pile foundations are mostly used as the foundation structure for offshore wind measuring towers. However, due to the harsh offshore environment, the construction period of wind measuring towers is long and difficult, and the efficiency of pile driving is low, resulting in high construction costs. Therefore, it is reasonable to choose offshore wind towers. The construction foundation and construction technology of the wind measuring tower have become a serious consideration in offshore engineering. A wind measuring tower foundation with economical safety, simple structure and short construction period has become the key to solving the problem
