Problems solved by technology

The technology of the above-mentioned related erosion protection measures is relatively mature, and there are a large number of engineering examples. However, the protection principle embodied in the pile foundation erosion protection measures is to use the protective layer to protect the soil around the pile foundation to resist water erosion, and it cannot slow down the wave. Flow velocity to fundamentally control the effect of pile foundation scour

Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0022] As shown in the figure, an anti-scour sleeve for offshore wind power monopile foundations includes an anti-arc section sleeve, a soil-entry section sleeve, a first annular reinforcement rib and a second annular reinforcement rib, and the anti-arc section sleeve is trumpet-shaped , with the larger opening facing downwards, the lower end of the anti-arc section sleeve is connected to the soil-entry section sleeve by welding, the soil-entry section sleeve is a hollow cylinder, and the inside of the anti-arc section sleeve is provided with a first annular reinforcing rib and a second The ring-shaped reinforcing rib, the inner diameter of the lower edge of the anti-arc segment sleeve is equal to the inner diameter of the soil-entry segment sleeve.

[0023] The inner diameter of the upper edge of the anti-arc segment sleeve is larger than the o...

Abstract

The invention discloses an offshore wind power single pile foundation scour prevention sleeve. The offshore wind power single pile foundation scour prevention sleeve comprises a reverse arc section sleeve, an embedded section sleeve, a first annular stiffening rib and a second annular stiffening rib. According to the offshore wind power single pile foundation scour prevention sleeve, the arc structure of the reverse arc section sleeve is used for adjusting water flow direction and flow rate, and the erosion degree of soil around the pile is reduced by the reducing of erosion energy of a pile foundation; the offshore wind power single pile foundation scour prevention sleeve is simple in structure, and can achieve land prefabrication; the installation steps are easy, after the installation of the pile foundation, the scour prevention sleeve is sleeved on a pile head directly and is sunk in to the soil by self weight, the construction is convenient, and the construction cost of pile foundation scour prevention is greatly saved.

Description

technical field [0001] The invention relates to an anti-scouring sleeve for offshore wind power single pile foundations, in particular to an anti-scouring device for offshore pile foundations which utilizes the anti-arc structure of the anti-arc segment sleeve to protect the soil around the pile and reduce the flow rate of water flow, belonging to marine engineering technology field. Background technique [0002] Energy is the core resource for the development of modern society. With the depletion of traditional energy, the development of new energy is imminent. Among them, wind power, as a clean and renewable new energy, is more and more widely used in the form of wind power in the development of modern society. By the end of 2009, the global cumulative installed capacity had reached 159 million kilowatts. The new installed capacity exceeded 30 million kilowatts, an increase of 31.9%. In my country, by the end of 2012, a total of 389.6MW of offshore wind power projects ha...
