Problems solved by technology

[0005] Traditional drilling rigs adopt full-section rock-socketing technology. Due to the large drilling area, a large area of ​​core that does not need to be drilled is removed; resulting in low drilling efficiency and high requirements for rock-socketing equipment, and there are huge equipment, equipment low cost, high cost

Abstract

The invention provides an offshore support foundation. The foundation includes a steel pipe pile extending in up and down directions; the steel pipe pile includes an upper supporting section and a lower supporting section; the lower end of the upper supporting section extends to the top surface of the bedrock of seabed; the lower supporting section is embedded in the bedrock; and the upper end ofthe lower supporting section is fixedly connected to the lower end of the upper supporting section. The steel pipe pile includes the upper supporting section and the lower supporting section; the upper supporting section is located in a covering layer above weak weathered rocks; the foundation can be realized by adopting two construction methods which are a pure piling type and a drilling, pile sinking and concrete pouring type; and the lower supporting section is embedded in the bedrock, so that the supporting strength and stability of the steel pipe pile can be effectively enhanced by utilizing the supporting and limiting functions of the bedrock on the lower supporting section, the steel pipe pile can be prevented from generating large translation and shaking, and therefore, the supporting strength and stability of the foundation can be higher.

Description

technical field [0001] The invention relates to a foundation structure, in particular to an offshore support foundation. Background technique [0002] As the renewable energy with the most exploitable value, wind energy has attracted worldwide attention. Offshore wind farms have good prospects for development because of their advantages such as high wind speed, long effective power generation time, no land occupation, and close distance to load centers. my country has a vast territory, long coastline, and abundant offshore wind energy resources. [0003] Offshore wind turbines must be supported on the offshore wind turbine foundation. Due to the complexity of the marine environment, the foundation cost of offshore wind turbines accounts for more than 20% of the cost of offshore wind farms. How to reduce the cost of wind turbine foundation, reduce the construction period of offshore wind turbine foundation, promote wind farms to generate electricity as soon as possible, an...
