Abstract

The invention relates to the technical field of marine engineering, and discloses a design method for a single pile fan foundation with ventilation and water-changing functions. The design method comprises the following steps that first, one or more ventilation holes and one or more drain holes are formed in a steel pipe pile, the heights of the ventilation holes are higher than the extreme high water level, and the heights of the drain holes are lower than the high tide level and higher than the low tide level; and second, the steel pipe pile is driven into a seabed and fixed. Through the design method for the single pile fan foundation with the ventilation and water-changing functions provided by the invention, the problems of seawater metamorphism and bad smell emission in a single pilecan be solved.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a design method for a single-pile fan foundation with functions of exchanging air and water. Background technique [0002] With the maturity of offshore wind power generation technology, the way of using offshore wind power generation is gradually favored by people. At present, Hebei, Shandong, Jiangsu, Zhejiang, Shanghai, Guangdong, Fujian and other coastal provinces have successively launched offshore wind power projects. [0003] The monopile foundation is the most widely used foundation form in the field of offshore wind power engineering. It has a simple structure, quick construction, and high cost performance. Generally, steel pipe piles with a length of 4m to 8m are directly driven into the seabed, and the submarine cable is driven from the mud surface. The traction fan foundation is on the outer platform and enters the tower. At present, in wind farms with a ...
