Intelligent Sensing and Analysis Technology for Geological Hazards with "Cloud-Edge-End" Collaboration is provided by the Beijing Municipal Engineering Research Institute. Aiming at the major demand for leakage control of existing subway structures caused by complex environments such as the continuous rise of groundwater level in Beijing, and relying on special projects of the Beijing Municipal Science and Technology Commission and subway operation companies, this achievement has systematically developed key technologies for leakage disease control of subway structures with international advanced level. This technology breaks through the bottlenecks of traditional methods such as weak pertinence, repeated leakage and limited construction window, constructs a three-dimensional waterproof system of "occurrence environment improvement - structural performance enhancement - internal boundary reinforcement", forms a complete technical system covering 23 basic processes and 6 special processes, and realizes the collaborative improvement of detailed and accurate repair and overall waterproof performance. It effectively overcomes the on-site implementation difficulties such as the short "window period" and the interference of train vibration. This achievement has reached the international advanced level, and has been applied on a large scale in Beijing, Nanjing and many other places, with significant economic and safety guarantee benefits.
