This paper introduces digital minor-disturbance deep mixing technique consisting of a rig frame platform, a mixing system, a digital construction system, an air supply system and an automatic slurry plant. The construction process is controlled by the digital construction system, and the construction data is uploaded in real time to the cloud platform. This novel techniques involve triple-channel hexagon-shaped rod, variable binder content mixing and inner stratum pressure control, leading to mitigating construction impact on the surrounding soil and enhancing installation efficiency and quality. A field test was conducted to verify the performance of this technology. The recorded construction parameters, including slurry flow rate, drilling speed, air pressure, and inner stratum pressure, were consistent with the required values. The measured soil lateral displacements and ground heaving, influenced by the pile construction, remained below 5 mm. The unconfined compressive strengths were uniform at approximately 1.1 MPa along the pile shaft.
