Offshore wind power multi-pile foundation integral berthing anti-collision structure and construction method

Abstract

The invention provides an offshore wind power multi-pile foundation integral berthing anti-collision structure and a construction method. The offshore wind power multi-pile foundation integral berthing anti-collision structure comprises a berthing anti-collision component, a grouting fixing component and an inclined pile; the berthing anti-collision component is used for berthing a ship and plays a buffering role to prevent a berthing ship body from directly colliding with a pile body; the side, close to the inclined pile, of the berthing anti-collision component is fixed to the inclined pile through the grouting fixing component; the inclined pile is sleeved with the grouting fixing component, and the outer side wall of the grouting fixing component is connected with the berthing anti-collision component; and the inner side of the grouting fixing component and the inclined pile are fixed through grouting. According to the offshore wind power multi-pile foundation integral berthing anti-collision structure and the construction method, the berthing anti-collision component and the grouting fixing component are integrated, installation can be completed only through one-time hoisting, finally, fixing is conducted through grouting between the grouting fixing component and the pile body, and field welding and splicing are not needed. The integrated berthing anti-collision structure is high in integrity, good in stress performance, few in offshore construction procedure, short in construction time, small in field operation amount and short in ship machine equipment occupation time.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power, and in particular relates to an integral anti-collision structure and construction method for a multi-pile foundation of offshore wind power against ships. Background technique [0002] Multi-pile foundation is a commonly used foundation form for offshore wind power. It has a large number of applications in shallow water areas in the southeastern coastal areas of China, and is often used as the foundation form for offshore wind power. The multi-pile foundation generally uses several inclined piles, and the inclined piles are poured together through the cap to form a unified whole. The upper part of the cap is connected to the tower of the offshore wind turbine. [0003] In actual engineering, the offshore wind power foundation needs to be equipped with a ship berthing anti-collision system for berthing of the hull and landing of personnel. The traditional anti-collision system for be...

Problems solved by technology

The traditional anti-collision system for berths requires on-site welding at sea, and the individual berthing components need to be welded on the pile body after piling is completed. The site workload is heavy, the construction quality is not reliable, and it needs long-term occupancy of ships for hoisting and fixing. operations, therefore, increasing the difficulty and cost of construction, resulting in a waste of resources
