TUNNEL EXCAVATING METHOD HAVING BUILDING STEP COMMUNICATION LINES FOR REAL TIME OBSERVATING AND MONITORING A TUNNEL WORKING FACE

摘要

The present invention relates to a construction method and a system capable of monitoring the tunnel excavation situation and the state of the excavation tunnel in real time by observing in real time the information collected on the excavation tunnel's membrane scene as well as the field observer and the remote center supervisor. More specifically, after the blasting for tunnel excavation, the communication line is extended to a non-communication area, and a vehicle-based multi-sensor measuring system (MMS) is entered into the excavation tunnel's end face to close the end of the excavation tunnel. A tunnel excavation method and an observation system of a communication line construction method for real-time observation and monitoring that collects information on a surface and enables communication and monitoring in real time, the tunnel excavation step; A reinforcement step in which an internal structure is extended to the excavation tunnel to a length corresponding to the excavation depth of the tunnel; A communication line extension step in which a communication line between a communication repeater and a setup box is additionally extended along an internal structure so that wireless communication is possible in a closed section of the tunnel; An MMS setup step in which a multi-sensor measuring system (MMS) mounted in a vehicle enters the closet section, and a control mobile of a field observer and the MMS access and communicate with a remote server via a communication repeater; A membrane scene surveying step in which the MMS surveys the membrane scene of the excavation tunnel and transmits the collected survey data to a remote server, and the control mobile receives the survey data; It includes a; MMS withdrawal step of withdrawing the MMS from the closest section for subsequent excavation of the excavation tunnel.
