| description | The invention belongs to the technical field of buildings and relates to a high-pressure injection grouting expanded-base inlaid-type pile and a preparation method, in particular to an improved expanded-base pile structure and a preparation method. The upper section of a pile body is one of a concrete grouting pile, a reinforcement cage concrete grouting pile, a precast pile, a precast tubular pile and a steel tube pile, the lower section of the pile body is a high-pressure injection grouting reinforced body with the diameter larger than that of the upper section of the pile body and the lower end of the upper section of the pile body is embedded into a reinforced body of the lower section. According to the high-pressure injection grouting expanded-base inlaid-type pile and the preparation method, the pile body structure is simple, construction cost is low, the technology is simple, the size and quality of the expanded-base section are easy to accurately control according to design requirements, the pile body |
