AI Technical Summary
When mixing cement slurry and soil, the existing cement-spraying pile mixer has poor mixing effect and poor ease, resulting in uneven mixing and uncompromising, which in turn affects the quality of the foundation.
A four-axis cement-spraying pile mixer is adopted. By combining the four-axis of the grouting rotor shaft and the gas injection rotor shaft, combining the high and low arrangement of the first nozzle and the second nozzle, and the up and down rotation of the first stirring leaf and the second stirring leaf, the uniform mixing and compact filling of the soil and cement slurry are achieved.
Through the combined action of high-pressure jetting and stirring leaves, the soil and cement slurry are increased, forming a slurry-soil-soil-soil-soil-combination. The cement slurry and soil are mixed more uniformly and densely, significantly improving the stability and reliability of the foundation.
