Abstract

Aiming at the problem of quality control of a deep mixing pile in construction process, this paper introduces a novel digital construction cloud platform incorporated in the equipment minor-disturbance four-axial soil mixing pile, realizing the real-time tracking and feedback in construction process. After inputting the parameter related to different strata into the platform, the variation of parameter is automatically controlled in construction. After inputting the threshold of underground pressure, the minor-disturbance to subsoil is realized with a measured soil lateral displacement and upheaving in millimeter scale. With a measurement of verticality of drill rod in real time, the pile verticality can be controlled to 1/250. The management cloud platform realizes a dynamic management of quality control for all parties in the construction. This practical results are beneficial to completely improve the construction quality of the deep mixing pile and digital construction level of soft soil.
