Abstract:

Beijing underground rail transit work, which is located in the downtown area of Beijing, mainly crosses waterrich and sandy cobble stratum. The construction of the project is difficult and full of risks. An integrated allround 3D realtime construction information feedback system is adopted by using videolized information feedback system, which consists of videolized warning system, videolized monitoring system, entrance guard system, shield boring parameter control system and information feedback system. Realtime, accurate and videolized information feed back is achieved and the construction safety is guaranteed.

Key words: rail transit, Beijing underground rail transit work, videolized information feedback system, videolized warning, videolized monitoring, entrance guard system, shield boring parameter control system
