A high pile cap foundation structure

Abstract

The invention discloses a high pile cap foundation structure, which comprises a concrete cap higher than sea level, and a group of steel pipe piles arranged at the bottom of the concrete cap for supporting the cap, and the upper part of the steel pipe pile is embedded in the bottom of the cap , the group of steel pipe piles is distributed at the bottom of the cap in a frustum-cone shape, and a climbing ladder for climbing up the cap is provided on one side of the cap. There are anti-collision poles, anode active metals and wiring pipes are arranged on the steel pipe pile, an outwardly extending platform is arranged on the cap platform, and a crane and more than one container are arranged on the cap platform or the platform. In the high pile cap foundation structure of the present invention, since connecting rods are arranged between adjacent steel pipe piles, the overall rigidity and strength of the high pile cap foundation structure can be improved, and the anti-collision rods arranged on the connecting rods can prevent The operation and maintenance ship directly hits the steel pipe pile; the setting of the platform expands the usable area on the cap; containers and cranes can be set on the platform to facilitate the operation, maintenance and work 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.
