Problems solved by technology

[0003] At present, the anti-scour design concepts of offshore wind turbine foundations can be divided into two categories: one is that no anti-scour measures are taken, and the depth of scour pits is only determined according to calculations or models, and the supporting role of this part of the soil layer is not considered in foundation design , this method will inevitably greatly increase the pile length, which is neither economical nor conducive to construction; another concept is to adopt anti-scouring measures.

Embodiment Construction

[0020] The present invention will be further described below with reference to the drawings and specific embodiments.

[0021] Such as Figure 1-2 As shown, a cage-type anti-scouring structure includes an anti-scouring member sheathed at the bottom of a pile foundation, the anti-scouring member is a geobag in a ring shape, or the anti-scouring member is surrounded by a plurality of geobags. It is a mesh with a certain width and is a water-permeable geosynthetic material made of synthetic fibers through needle punching or weaving, and has strong corrosion resistance. Each geobag can be formed by tying, tying, consolidating, etc. An annular structure, for example, adjacent geo-bags are tied by ropes, and a number of anti-scouring units are placed in the geo-bags. The anti-scouring units are surrounded by four tires in a cone shape. The tires are corrosion-resistant and rigid rubber materials. It can be a high molecular polymer such as polypropylene and polyvinyl chloride. The adja...

Abstract

The invention relates to a cage type anti-scouring structure and a construction method. The structure comprises an anti-scouring piece sleeving the bottom of a pile foundation. The anti-scouring pieceis an annular soil bag, or the anti-scouring piece is in an annular shape formed by a plurality of soil bags, the adjacent soil bags are bound and connected through ropes, a plurality of anti-scouring units are placed into the soil bags, each anti-scouring unit is in a conical shape formed by four tires, the adjacent tires are connected through one or more bolts, and bag openings of the soil bagsare bound and sealed by ropes. The anti-scouring structure is reasonable in design, abundant in material source, convenient to construct, economical and reasonable in manufacturing cost and remarkable in anti-scouring effect, the foundation seabed stability is enhanced, the anti-scouring capability of structures is greatly improved, and the anti-scouring structure is applicable to all water depthranges.

Description

[0001] The invention relates to a cage type anti-scouring structure. Background technique [0002] In recent years, my country's offshore wind power has developed rapidly, gradually developing in the direction of deep sea and open sea. As the water depth and marine environment continue to change, the pile diameter of the wind turbine foundation increases, and the sea conditions become more complicated. The seabed scour will have a serious impact on the overall stability of the wind turbine foundation and has become a part of the overall stability analysis of the wind turbine that cannot be ignored. . [0003] At present, the anti-scouring design concept of the foundation of offshore wind turbines can be divided into two categories: one is that no anti-scouring measures are taken, and the depth of the scouring pit is determined only based on calculations or models, and the supporting role of this part of the soil layer is not considered in the foundation design. This method will in...
