Description

TECHNICAL FIELD

[0001] The utility model relates to offshore wind power construction technical field especially relates to a geotextile scour protection structure. BACKGROUND

[0002] With a large number of offshore wind power engineering projects put into operation, the scour problem of wind turbine pile foundation is increasingly prominent, which should be fully considered in engineering practice. As for the scour protection technology of offshore wind turbine pile foundation, many scholars at home and abroad have done a lot of theoretical research work. At present, the offshore wind turbine foundation commonly adopts scour protection methods such as riprap, sand blanket and sand bag. However, due to the complex offshore environment, the riprap and sand bag offshore construction period is long, and it is difficult to throw into place, so the construction is difficult to achieve the design intention, which seriously affects the protection effect. Although the sand blanket can save offshore operation time and has relatively fast efficiency, due to the construction and other reasons, there is still a large gap between the pile and the sand blanket in the currently operated offshore wind farm, and the protection effect is still not ideal. A large scour pit has been formed around part of the pile foundation. If the scour protection fails, the horizontal resistance of the wind turbine foundation is reduced, which threatens the safety of the wind turbine. If the scour pit is large, the submarine cable is suspended for a long time, and there is also a risk of submarine cable damage.

[0003] To solve the above problems, we propose a geotextile scour protection structure. CONTENT OF THE UTILITY MODEL

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a geotextile scour protection structure, and the utility model provides the following technical scheme:

[0005] A geotextile scour protection structure is composed of geotextiles arranged in a circle and in a circular structure. The geotextile is an isosceles triangular structure. The geotextile is arranged in a circle and closed structure with the wind turbine as the center in a clockwise direction. The geotextile is uniformly provided with a cylindrical cavity in the transverse direction. The triangular edge of the geotextile is surrounded by a cylindrical cavity. The left and right sides of the geotextile are extended to be provided with a rectangular narrow wing. The narrow wing on one side is provided with the cylindrical cavity, and the cylindrical cavity is provided with barite. The narrow wing provided with the cylindrical cavity on one side of the geotextile is pressed on the upper side of the adjacent geotextile provided with the narrow wing without the cylindrical cavity and is sewn and connected.

[0006] Preferably, the cylindrical cavity is a cylindrical structure sewn on the geotextile.

[0007] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0008] The structure is simple and convenient for construction. Based on the fact that barite has large specific gravity and stable chemical properties, the protection effect is more durable. After the structure is assembled, the overall structure has a large and more uniform area coverage, and the protection effect is more prominent. DRAWINGS
