In general, the increase of the capacity of a single machine of a wind turbine generator can lead to the increase of the basic size of a wind turbine, but the preliminary material preparation work of low-capacity wind turbine basic steel is finished due to the longer development period of offshore wind power. Therefore, in order to meet the needs of the owners, the modification of the existing single-pile foundation type to meet the operation requirements of the high-capacity wind turbine generator system becomes a problem which is currently concerned by many owners.

At present, single-pile foundations in the field of offshore wind power are divided into two types according to construction processes, wherein one type is an embedded rock single pile, and the other type is a non-embedded rock single pile. The construction process includes drilling hole, implanting single pile foundation and injecting high strength grouting material into the annular space between the side of the single pile foundation and the drilled hole.
Therefore, a simple offshore wind power rock-socketed single pile reinforcing structure is needed.
