Abstract: The present invention relates to pile foundations and provides an intelligent construction control method and system for jet grouting piles based on stratum information inversion. This method integrates multi-source sensing components and local transmission to perceive real-time drilling information to a data integration terminal. Using engineering soil layer data as training samples, a machine learning algorithm correlates perception information with geological conditions, judging and outputting stratum conditions in real time. An XGBoost model quickly and accurately identifies soil layers at the site. Based on big data matching of a cloud platform, an optimal construction parameter database is established, and the optimal combination of parameters is acquired through algorithm matching. A variable-frequency and variable-speed pressure adjusting device links a piling machine intelligent control system with other subsystems to achieve intelligent control, reducing material consumption and improving pile quality and efficiency.
