Abstract

The invention discloses a maritime foundation base. The maritime foundation base comprises a barrel-shaped base and a connecting tower barrel; a sealing top cover is arranged on the upper part of the barrel-shaped base; the connecting tower barrel is arranged on the sealing top cover; an inner barrel is sleeved inside the connecting tower barrel; and a soft cushion layer is arranged between the connecting tower barrel and the inner barrel. By adoption of a structural design that the inner barrel is arranged inside the connecting tower barrel and the soft cushion layer is arranged between the connecting tower barrel and the inner barrel, the shock-proof safety of the maritime foundation base is enhanced greatly; meanwhile, the shortcoming that the maritime foundation base uses a large quantity of materials can be avoided; therefore, the cost is reduced and a good stress effect can be achieved.

Description

Technical field

[0001] The invention relates to the technical field of infrastructure in port, ocean, water conservancy and bridge engineering, and in particular to an offshore foundation of a wind turbine. Background technique

[0002] At present, the structural type adopted for offshore foundations of wind turbines is usually single-pile foundation, multi-pile foundation, jacket foundation or gravity foundation. Both single-pile foundation and multi-pile foundation belong to pile-driving support piles, which are greatly restricted by the geological conditions and water depth of the seabed; special equipment (such as drilling equipment, etc.) is required for installation, resulting in high construction and installation costs; Erosion is sensitive and requires special anti-corrosion, strength and toughness requirements. The scope of application of jacket foundation is very narrow. As the water depth increases, the cost increases exponentially. The gravity foundation is generall...
