High-pile bearing platform foundation structure

Abstract

The invention discloses a high-pile bearing platform foundation structure. The high-pile bearing platform foundation structure comprises a concrete bearing platform which is higher than the sea level and a steel pipe pile set which is arranged at the bottom of the concrete bearing platform and used for supporting the concrete bearing platform. The upper portions of steel pipe piles are embedded in the bottom of the bearing platform. The steel pipe piles are distributed at the bottom of the bearing platform in a frustum shape. A crawling ladder is arranged on one side of the bearing platform, wherein a person can climb up the bearing platform through the crawling ladder. Connecting rods are arranged between adjacent steel pipe piles. The connecting rods which are located on one side of the crawling ladder are provided with bumper bars. The steel pipe piles are further provided with anode reactive metal and wiring pipes. A platform which extends outward is arranged on the bearing platform. The bearing platform or the platform is provided with a crane and one or more containers. According to the high-pile bearing platform foundation structure, the connecting rods are arranged between adjacent steel pipe piles, and therefore the overall stiffness and strength of the high-pile bearing platform foundation structure can be improved; the bumper bars arranged on the connecting rods can prevent an operation and maintenance ship from directly impacting the steel pipe piles; the arrangement of the platform enables serviceable area on the bearing platform to be enlarged; the container and the crane can be arranged on the platform, which brings convenience to operation and maintenance as well as work and rest of technicians.

Description

technical field [0001] The invention relates to offshore wind farm foundations, in particular to a high pile cap foundation for offshore wind farms. Background technique [0002] At present, most of the development of offshore wind farms is concentrated in Denmark, Germany, the Netherlands, the United Kingdom, Sweden, Ireland and other countries in Europe. The foundation forms are dominated by single pile foundations, accounting for 74%, followed by jacket foundations, and other foundations such as gravity foundations, tripod foundations, suction foundations, portal foundations, negative pressure foundations, and floating foundations are relatively more widely used. few. It started relatively late in China, and the offshore wind turbine foundation platform was developed from the offshore oil production platform in the oil and gas industry. One of its applications is the foundation of high pile caps. [0003] The patent number is 200920198988.1, and the utility model patent...

AI Technical Summary

Problems solved by technology

[0004] The patent number is 201220297967.7, and the utility model patent titled "A High Pile Cap Foundation for an Offshore Wind Farm" discloses a high pile cap foundation for an offshore wind farm, including a cap and multiple piles, each pile The upper end of each pile is embedded in the cap, and the part of each pile embedded in the cap is fixed with a reinforcing ring. The utility model effectively solves the problem that cracks are easily generated on the contact surface between the foundation pile and the concrete of the existing high pile cap in the offshore wind farm. leading to problems with compromised infrastructure

[0005] Although the existing high-pile cap foundation structure has its own advantages, it lacks auxiliary equipment and devices such as operation and maintenance and berthing as a whole, and lacks functions such as cable routing and personnel work and rest space.
