Maritime foundation base

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...

AI Technical Summary

Problems solved by technology

The gravity foundation is generally a reinforced concrete structure or a mixed structure of reinforced concrete and ballast, which has high requirements for the load-bearing foundation and requires seabed preparation in advance; due to its large volume and weight, it is very inconvenient to install and is greatly affected by the climate. higher cost

[0003] Using the above traditional offshore foundations, the foundation construction and offshore construction costs are expensive, resulting in a substantial increase in the investment cost of offshore foundations compared with onshore wind turbine foundations, thus limiting the development of offshore wind power

For the cylindrical foundation, at present, all-steel cylindrical foundations have been adopted in foreign countries, and the structural types adopted include single-tube and multi-tube types, but the cost is very high
