Summary:A construction method for a large-diameter onshore four-shaft mixing pile is discloses. The relation between the designed embedded layer top elevation and the drilling current and change characteristics of a mixing pile machine is established through trial insertion, and the actual embedded layer top elevation is judged by referring to the designed embedded layer top elevation and the drilling current value in the construction process; the influence of factors such as the thickness of an embedded soil layer, the length of a slurry conveying pipeline, a stirring drill bit and the cutting frequency of a pile bottom on the construction process is considered, and slurry in the slurry conveying pipeline is fully utilized; and the construction technology provides improvement measures and reinforcement measures for weak quality positions such as the upper and lower guniting lap joint position, the pile bottom and the pile top of the mixing pile. The scheme has the advantages of being high in construction speed, good
