A two-ring grouted single pile foundation is a foundation which is made up of hard components of an internal ring and an external ring. Part areas of the internal and external rings are connected by grouting. The foundation can provide great horizontal resistance and basic stiffness, and is suitable for basic fields of wind power generation, ports, offshore platforms and the like. On the basis of a behavior of a laterally loaded pile under load and making full use of material properties of steel and concrete, two rings or steel pipes with different inner and outer diameters are adopted. The internal and external rings are successively sunk into foundation soil in various ways (excavating and placing, driving, pressing and shocking). The foundation soil of the area which is close to the ground (soil surface) between the internal and external rings is excavated and materials such as concrete are grouted. If necessary, a reinforcing body can be inserted. Thus, the two-ring grouted single pile foundation is formed. The foundation makes full use of the concrete compressive property and the steel tensile property, and compared with a large-diameter steel pipe pile can effectively reduce an outer diameter of the pile foundation and steel consumption. When in water environment such as in the sea, an environmental load on the foundation is greatly reduced and construction difficulty is correspondingly reduced. The foundation can provide great horizontal resistance and basic stiffness, and can be applied to situations of bearing great horizontal load or passive earth pressure by using the foundation and can be applied to basic designs of onshore wind power generation, offshore wind power generation, ports, and offshore oil platforms.
