Abstract
The utility model discloses a honeycomb type erosion-proof and siltation-promoting structure for offshore wind power single pile foundation, which comprises a honeycomb device and an anchoring system, wherein the honeycomb device is a flexible structure formed by a plurality of honeycomb cells through ultrasonic welding, and the side surface of each honeycomb cell is provided with a hole; when in use, the honeycomb device is expanded to a grid state around the offshore wind power single-pile foundation by applying tension to the honeycomb device through the anchoring system.
Description
Technical Field
The utility model relates to an offshore wind power engineering technical field especially relates to a honeycomb formula scour protection short silt structure for marine wind power single pile basis.
Background
In recent years, offshore wind power has become a research hotspot in the direction of developing clean energy in various countries, the coastline of China is long, islands are numerous, and China also divides offshore wind power into important components of strategic emerging industries. But the complex marine environment can have adverse effect on the stability of the offshore wind power pile foundation, and further cause huge damage to the offshore wind turbine. Especially, the single pile foundation which is most widely applied is extremely easy to be washed by water flow and waves, and the stability of the fan is seriously threatened.
The commonly used riprap protection at present easily produces the secondary and erodes, and the portion that is closer to the pile footpath erodes deepening. Therefore, a novel erosion-preventing and silt-promoting structure for protecting the surrounding bed of the offshore wind power single-pile foundation, preventing the surrounding bed from being locally scoured under the action of wave current and promoting the sedimentation and siltation of the ocean current carrying sand is urgently needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough among the prior art, provide a can protect offshore wind power single pile basis bed on every side, prevent that it from taking place the part under the wave current effect and erode to can promote the structure of the sedimentation siltation that the ocean current was taken sand.
The utility model aims at realizing through the following technical scheme:
a honeycomb type erosion-resistant and siltation-promoting structure for an offshore wind power single-pile foundation comprises a honeycomb device and an anchoring system, wherein the honeycomb device is a flexible structure formed by welding a plurality of honeycomb cells through ultrasonic waves, and the side surface of each honeycomb cell is provided with a hole; when in use, the honeycomb device is expanded to a grid state around the offshore wind power single-pile foundation by applying tension to the honeycomb device through the anchoring system.
Furthermore, the coverage area of the honeycomb device is larger than that of the local scouring pit, and is 5 times of the diameter of the single pile.
Furthermore, the holes arranged in the honeycomb device have water permeability, and are beneficial to the biological activity and the material transportation in the seabed soil layer.
Further, the mooring lines of the anchoring system are connected at one end to the honeycomb device and at the other end to an anchoring device which is fixed in the seabed.
Further, the cable and the anchoring device of the anchoring system are both subjected to corrosion resistant treatment.
Compared with the prior art, the utility model discloses a beneficial effect that technical scheme brought is:
the seabed roughness can be effectively increased, the flow of the water body at the bottom layer is slowed down, so that the silt carried by the water body falls off and is gradually accumulated among the honeycomb cells, the effect of protecting the seabed around the pile foundation to prevent scouring and promote sedimentation is realized, and the secondary scouring phenomenon can be effectively weakened; the influence on the biological activity and the material transportation in the seabed is small, and the balance of a seabed ecosystem is maintained; the structure is simple, and the structure has the advantages of better integrity and durability, small construction and maintenance engineering amount and the like.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 to 2, a honeycomb erosion-proof and siltation-promoting structure for offshore wind power single pile foundation is composed of a honeycomb device 1 and an anchoring system 2. The honeycomb device is formed by hot pressing high polymer materials, through holes 11 are arranged on honeycomb cells, and adjacent honeycomb cells are tightly connected through ultrasonic welding seams 12 to form a whole. The honeycomb device forms a flexible net structure through the tension action of the anchoring system 2 and is fixed on the seabed surface near the offshore wind power single pile foundation. The coverage area of the honeycomb device is slightly larger than the range of the local scouring pit, and is about 5 times of the diameter of the single pile. The honeycomb type erosion-proof silt-promoting structure greatly increases the roughness of the seabed after completion, and makes the bottom water flow slow down, so that silt carried by the water falls off and gradually deposits between the honeycomb cells, and the effect of protecting the seabed around a pile foundation, preventing scouring and promoting deposition is realized.
The present invention is not limited to the above-described embodiments. The above description of the embodiments is intended to describe and illustrate the technical solutions of the present invention, and the above embodiments are merely illustrative and not restrictive. Without departing from the spirit of the invention and the scope of the appended claims, the person skilled in the art can make many changes in form and detail within the teaching of the invention.
