Abstract
Conventional soil–cement columns fail to fully consider the layered structure of foundation soil, resulting in cement waste. Owing to the concealment of the installation site, soil–cement mixing column installation is labor-intensive, and its quality is considerably affected by the skills and experience of the laborers and operators. In this study, soil–cement mixing column installation technology and quality control were investigated by improving the automation and intelligent ability of installation equipment based on the Internet of Things (IoT) technology. An intelligent soil–cement mixing column driver was developed. Field test and engineering application results showed that frequency grouting, installation quality assessment, and on-site and remote monitoring can be implemented. The intelligent soil–cement mixing column driver improved the installation capacity and quality, reduced the cost, and simplified the construction management. The intelligent soil–cement mixing column driver has great potential for engineering applications and development. In the future, a wider range of applications and further intelligent upgrades will be investigated.
