Abstract: Since cement grouting project is a hidden work, it is difficult to check and control the grouting quality directly. Automatic monitoring of the grouting parameters is thus very crucial. In this paper we made a review on the technological progresses and the process of developing automatic grouting recorder, and expounded the development of digital grouting monitoring system. Also we looked into the future of intelligent grouting recorder, intelligent monitoring cloud platform, anti-counterfeiting of online monitoring data, as well as BIM+GIS-based monitoring system integrating latest achievements of modern electronic technology, Internet of Things technology, big data technology, and blockchain technology. The intelligent monitoring systems are beneficial for the safety and quality of hydropower projects, and will reduce cost and promote the management of project construction.

Key words: grouting works, grouting recorder, automatic monitoring, grouting equipment, Internet of Things technology, big data technology
