AI Technical Summary

Technical Problem

The foundation of offshore wind power single pile is easily damaged by erosion, and existing bottom protection protection measures are difficult to effectively isolate the water flow around the pile, resulting in poor erosion protection effect.

Method used

The honeycomb anti-shrink structure is adopted, and the soil around the pile is directly covered by the shell structure and the honeycomb unit, the water flow direction is adjusted, and the anchors and bionic grass materials are used to deposit sediment inside the honeycomb unit to enhance the protection effect.

Benefits of technology

Effectively prevent water flow from eroding the soil around the pile, reduce construction costs and environmental impacts, and improve the stability and service life of single pile foundations.

Abstract

The invention relates to an offshore wind power single pile foundation honeycomb type anti-scouring structure and a mounting and anchoring method, and belongs to the technical field of offshore wind power single pile foundation protection. The invention discloses a honeycomb type anti-scouring structure of an offshore wind power single pile foundation. The honeycomb type anti-scouring structure comprises a shell type structure, honeycomb units and anchoring parts. The honeycomb type anti-scouring structure takes the single pile foundation as the center and is arranged at the bottom of the single pile foundation; honeycomb units formed by splicing a plurality of cells are laid on the shell type structure; the honeycomb units comprise anchoring parts; the shell type structure covers the soil body around the single pile foundation, and the anchoring part is inserted into the soil body around the single pile foundation. Rock, sand bags and the like do not need to be transported, so that the construction cost and the influence on the environment are reduced; according to the bionic grass, the soft fabric material is adopted as the main body strip, and the bionic grass has the advantages of being simple in process, good in durability and high in stability after being fixed.
